Description

538215 --- 9-1112322_Year month and month Amendment ____ — V. Description of the invention (2) '" _' ~ · Storage: ^ 38, etc.) The incineration ash is removed first. The incineration ash is harmful to the human body and mostly contains dioxin. Therefore, in order to prevent the incineration ash from scattering during the above-mentioned incineration ash removal operation, the incineration ash will be sprayed with water and sprayed water before the operation. The incineration ash attached to the inside of the incinerator device is turned over with a turning tool such as an iron brush. As for the incineration ash accumulated inside the incinerator device, the operator scoops it up with a shovel or the like and puts it into an iron bucket for storage. Inside to remove incineration ash. After the incineration ash in the iron bucket is dried, the iron bucket is covered and stored. [Problems to be Solved by the Invention] However, the previous method for removing incineration ash by spraying or spraying water on the incineration ash will cause the incineration ash to become watery and heavy, which will cause the incineration ash to be clocked and put into storage iron by using a tool such as a shovel. The operation of the barrel became a heavy labor operation. Today, water-containing incineration ash is easily attached to iron brushes, which makes cleaning operations such as iron brushes difficult after the incineration ash removal operation. The water sprayed on the incineration ash may contain dioxin, so it is necessary to set up a device that does not allow the water to flow to the outside, and the spraying ^ not only requires subsequent processing operations, but the subsequent processing operations are quite difficult . Furthermore, as described above, the incineration ash put into the iron bucket for storage contains water, so the incineration ash must be dried. 3 As mentioned above, previous incineration ash removal methods were accompanied by considerable industry and were very difficult.鉴于 In view of the above-mentioned factors, the present invention aims to provide an incineration ash removal method that can easily perform various operations generated when removing ash. ,

[Method to solve the problem] Attachment 荖: Two of the incineration ash removal method of the present invention is to deposit 4 of the incineration ash in the incinerator in the incinerator device. The invention borrows 1 work and ^ β β Ash removal method, this ^ cloth 1 in ^ Shengcheng, that is, before the incineration ash is removed before the incineration ash; μ / month removal of the gas state of the coolant in the mounting project. The Ben Sheming simplifies the operations of removing the cremation ash with the faeces, stubble, sacrifice, and sacrifice, and reducing the incineration ash in the incinerator device. Study on the method of alpha division of Fang Erhua gray ash accumulated in human fire. During the course of the research, the Ming dynasty described that the sprayed water for the purpose of preventing the incineration ash from scattering has made the operations associated with the removal of the incineration ash difficult, and has continued to cause research. It was found that, before disposing incineration ash before dispersing a coolant in a gaseous state in the incineration environment, the situation of incineration ash scattering can be reduced even without using water, which can make the various components generated during the incineration ash removal. The operation is simplified to achieve the purpose of the invention. The thinking method of the incineration ash removal method of the present invention is that if the coolant is dispersed on the incineration before the incineration ash is removed, the gas such as water vapor inside the incineration ash will be liquefied or solidified, which will increase the weight of the incineration ash. And even if the cleaning operation is carried out by flipping and scooping, the incineration ash will not fly away; by dispersing the coolant, the surrounding temperature of the incineration ash removal operation will drop, resulting in a descending airflow, which is also the rise of incineration ash. The reason why the incineration ash is prevented from flying away is hindered; further, because the cooling agent is distributed to reduce the surrounding temperature, the degree of "Brownian motion" of surrounding air molecules will be reduced, making

Page 10 538215 V. Description of the invention (4) Incineration ash is not easy. In the state of the cooling body, the medium will turn into aerosol. The incineration ash input after the incineration ash is incinerated ash will be removed. In addition, it is scattered, so there is no need to do it. It is scattered by the cleaning operation, and if the agent is dispersed in the incinerator, it will spread. It will not be cooler than the coolant entered after the storage iron bucket is dry and fluffy. The coolant does not need to be installed. The coolant derived from the present invention is incinerated ash. It should not be incinerated. The state of working labor such as watering, and the like, the bell incineration ash removal prevents the cooling of subsequent processing, the incineration ash removal operation becomes a simple flying removal operation, but the agent is heavy after incineration. In addition, the cleaning agent is easy to adhere, and the method is simple. The reason is that the environmental incineration ash & i is reduced, and the net operation of the shovel will be changed to the outside. The cooling can allow the partner to show the gas cleaning operation. The cloth should be cooled by a shovel and other coolant, making it easier to enter the gas and expand. The equipment's agent drying etc. with the incineration ash [this type 1) part 2) the incineration part ice powder invention implementation form] The following / prediction diagrams explain the implementation form of the present invention in detail. Fig. 1 is a method for removing incineration ash of the present invention, which is twice as high as, 杳 哈 stage 4 I #, and Besch-type evil. This: Γ inside the incinerator device (inside the main body of the incinerator: incineration: inside the ash incinerator device) (The method for the bottom ash of the main body of the incinerator. Just, remove the dry ice scattered on the incineration ash eight = the following is a more detailed description, first spread the age on the incineration ash 10. This #, this dry ice spreading operation uses dry placement to spread out and consists of the following elements:

Page 11 538215 V. Description of the invention (5) ^ ---- Liquid II, carbonization tank U, (2) Power officer 12 extending from the mouth of liquid carbon dioxide tank n, (3) Installed on this hose 12 on-off valve 13 and (4) nozzle 14 and (5) formed on the front end of this on-off valve 13 are installed in the barrel-shaped corner cup (H0RN) 15 of this nozzle. After the front end faces a part of the incineration ash A, the on-off valve 13 is opened; by this action, the dry ice will be ejected from the nozzle 14 through the corner cup 15 and spread on a part of the ash A. Iron When the incineration ash A scattered with dry ice is picked up by a turning tool such as a brush, the incinerated ash A that is lifted up will almost fall without scattering, the reason is that the water vapor and other gases inside the incineration ash partially dispersed with dry ice are scattered. It will liquefy and solidify, which will increase the weight, so when the incineration ash is picked up, it will fall directly without scattering, because the / JHL degree of the periphery of the incineration ash part where the dry ice is scattered will drop, resulting in a downdraft, so that The rise of incineration ash A is hindered, and the spread of coolant will reduce the surrounding temperature, The extent of the air molecules the Brownian motion "will be reduced, so that the incineration ashes A are less likely to scatter it. Then, the above-mentioned spreading of dry ice and the incineration of incineration ash are repeated, and the dispersing and invocation of the entire incineration ash A attached to the inside of the incinerator device is performed. Secondly, dry ice is dispersed in the above manner on (1) incineration ash A that has been accumulated in the incinerator device before the turning operation is started, and (2) a part of the incineration ash A that falls and accumulates during the lifting operation. At this time, the dry ice scattered before the pick-up operation will cause the cold air to drop, and the accumulated incineration ash A has cooled to a certain degree of privacy; as the cold air descends, the accumulated incineration

Page 12 538215 V. Description of the invention (6) The rise of ash A is hindered and it is not easy to scatter. The two used a shovel to disperse the incineration ash A into the storage iron bucket. Part of the incineration ash A from the dry ice was scooped up and thrown away, for the same reasons as the incineration ash A from each of the above inputs would hardly fly out. The operation of the barrel is carried out for the shoveling and throwing of iron by the male government cloth and the incineration ash A. The dispersing, shovel and throwing of the entire incineration ash A in the chemical plant is accumulated. The cremation ash 4 is removed, and the iron bucket is covered. The pressure is set to 1, and the pressure of 1 ^ is usually cleared from the pressure of the operating environment of the incineration ash person: ~ Tali is higher than the temperature when dry ice sublimates. (-70 ° c) =: The powdery dry ice will sublimate during the incineration ash A removal operation and become a mess and spread. With the above implementation mode, even if dry ice is scattered on the incineration ash A, the incineration fire A will not be heavier than in the past when it was sprinkled with water, which can reduce the shovel operation of the incineration ash A and the input operation of the iron bucket. The amount of labor. In addition, unlike in the past, the incineration ash sprayed with dry ice is dry and not attached to tools such as shovel, which makes the cleaning operation of the tool such as shovel after the incineration ash A clearing operation becomes more difficult. easily. Because the dry ice will become gas and diffuse during the removal of incineration ash A, unlike the previous situation of watering, it is not necessary to set up equipment to prevent the outflow of dry ice, nor does it require subsequent treatment of dry ice and the incineration ash A. Drying operation.

Page 13 538215 V. Description of the invention (7) In addition, in the past watering method, the operator worked in a state where the whole body was wet, which made the operation difficult, resulting in poor workability and efficiency, and If the operator's feet are wet, they will easily slip and become very dangerous. In view of this situation, during the incineration ash A removal operation described above, the scattered dry ice will become a gas and diffuse, so there is no danger that the conventional workability or work efficiency is reduced, and it is easy to slip. If an iron brush is used to pick up the incineration ash A attached to the inside of the incinerator device, an iron brush as shown in FIG. 2 can be used, that is, the installation base 2 2 made of metal bristles 2 丨 a spray type that sprays dry ice Iron brush 2 〇. The iron brush is embedded with powdery dry ice ejection nozzles 24 at the mounting base 22 of the iron brush, and the on-off valve 13 (see Fig. 1) of the dry ice spreading device 10 is buried at the handle 23 of the iron brush. When using the spray-type iron brush 20, 'the spray-type iron brush 20 can be used to distribute dry ice' and after spraying, the nozzle-type iron brush 20 can be used to lift up the incineration ash A while spraying dry ice. Therefore, incineration ash A is easier to cool, which can reduce the scattering of incineration ash. The operator does not need to use the dry ice spreading device 10 (see Figure 1) and the iron brush separately for the dry ice spreading and the incineration ash A. Only one spray iron brush 2 is required. Carry out this distribution and pick-up operation. In addition, 'this implementation type distributes dry ice', but the objects to be distributed are not limited to dry ice, as long as it is a coolant showing a gaseous sorrow in the environment where the incineration ash A is removed; especially liquid nitrogen (boiling point at 1 atmosphere) (About 196 ° C), liquid oxygen (boiling point is about 1 8 3 ° c at 1 pressure), liquid air (boiling point is about -94 Ό at 1 pressure), etc. are the same as dry ice, which is convenient for industrial use The use of coolant can reduce the scattering of incineration ash A, and can easily carry out the work that accompanies the removal of incineration ash A.

Description of the invention (8) Yue Xiu-When f is used to cool the dry ice and other coolants, and when the incineration ash A is removed, it is best for the operator to wear chemical protective clothing, chemical protective gloves, chemical Protection length and breathing protective gear, etc. At this time, the operator is best not to expose the skin of the pimple, neck, wrists and bare feet, especially the pressure requirements of the protective mask in the form of a full-face mask (PRESSURE-DEMAND ) Type air tube (AIRLINE) face mask (MASK), or full face mask type pressure air respirator is better. > The person will explain the examples and the comparative examples together. . In the laboratory, the incineration ash A was stacked into a cone shape with a diameter of 900 legs and a height of 500 coffee. Secondly, the dry ice was spread using the dry ice spreading device 10 in the manner described above, and then spread Immediately after the measurement: The internal temperature of the cone-shaped incineration ash from the apex of the center line of 300 bandits, Asia will incinerate ash A into a metal bucket with a shovel. During the operation, a certain amount of air was sucked from the open surface of the iron barrel at a height of 3,000 bands ^ * gas, and filtered by the filtration collection method (using the HVC-500 "HIGH VOLUME SAMPLER" filtration Collect the incineration ash by gravimetric method to collect, then measure the collection amount, and then calculate the concentration of scattered incineration ash A from the amount and amount of collection.
