Definitions

  • the invention relates to a belt drying system for drying bulk material such as sawdust, OSB strands or the like, in which a first, upper drying level for pre-drying comparatively moist bulk material, a second, lower drying level for post-drying of bulk material that has already been pre-dried on the upper drying level and an air duct of warm air is provided, with which warm air is first to be led through the lower drying level and then subsequently through the upper drying level.
  • Out SE 0 900 475 A1 is known a dryer for drying chopped wood material such as sawdust.
  • a first, upper belt is provided, on which a material is passed through a first drying section for pre-drying, and a second, lower belt, on which the material pre-dried on the upper belt is passed through a second drying section for post-drying.
  • an air duct is provided so that the heated dry air flows through first the lower drying section and then subsequently through the upper drying section each has to be guided from top to bottom.
  • a fan is provided in each case for generating negative pressure on the respective dry air.
  • a dryer with the same basic structure is known, which is designed with several modules that extend along an upper and a lower conveyor belt. One fan can be used for two modules.
  • the invention is based on the object of designing a belt drying system of the generic type in such a way that an effective drying of bulk material is still possible with a small footprint.
  • the invention is based on the knowledge that for a space-saving design of a belt drying system it is almost essential to design it with several levels, in particular an upper and a lower drying level.
  • the two drying levels preferably each have a separate, revolving drying belt on which the drying belt to be dried Bulk material is located and by means of which this bulk material passes through the belt drying system.
  • pre-drying is advantageously carried out on the upper drying level and post-drying is carried out on the lower drying level.
  • the advantage here is that the bulk material to be dried, after pre-drying, can flow down from the upper drying level to the lower drying level solely due to its weight and gravity.
  • the invention uses an air duct in which the hot air used to dry the bulk material is conveyed flowing downwards through the bulk material to be dried in the respective drying level.
  • the warm air used must first be passed through the post-drying area and then, when the warm air is already partially humidified, passed through the pre-drying area.
  • the solution according to the invention takes a different route and guides the warm air downwards through the bulk material to be dried.
  • Such air routing is more complex than air routing in which the warm air is routed through the drying levels from bottom to top, but the air routing according to the invention is also more effective.
  • the air duct according to the invention is advantageous when it comes to keeping the dust content in the warm air flowing through the bulk material to be dried low and also to keeping the exhaust air exiting the belt drying system as dust-free as possible.
  • the air flow according to the invention leads to the bulk material to be dried being kept compactly together and not being whirled up by the warm air. Further Dust particles are forced into the bulk material to be dried from above, but can only escape with difficulty due to the conveyor belt located there.
  • suction devices for sucking off the warm air from above downwards are provided as exhaust air under the respective drying level.
  • the suction can be carried out in sections by means of the suction devices. The suction creates a negative pressure in the bulk material to be dried, which further facilitates the evaporation of moisture there into the exhaust air to be discharged.
  • a first heating device for heating the warm air before it is fed to the upper drying level is also preferably provided on the belt drying system according to the invention.
  • the returned warm air can be increased in terms of its temperature level and thus prepared for absorbing further moisture.
  • This first heating device can operate at a comparatively low temperature level and heat recirculated warm air, preferably to a temperature of up to 130.degree. In this way, in particular, the risk of the bulk material to be dried igniting can be kept low.
  • the first heating device can be designed in an energetically favorable manner as a heat exchanger, in particular as a fluid heat exchanger. Process streams that are available from other parts of the plant as a source of residual heat can preferably also be used for the heat exchanger.
  • an admixing device for admixing fresh air with the warm air supplied to the upper drying level is preferably also provided.
  • the admixing device preferably mixes between 10 and 50 Percent by weight, preferably between 20 and 40 percent by weight and particularly preferably between 25 and 35 percent by weight of fresh air to the warm air supplied to the upper drying level.
  • a second heating device is also advantageously provided on the belt drying system according to the invention for heating up only the admixed fresh air before it is supplied to the upper drying level.
  • Such heating of the admixed fresh air alone has the advantage that only a comparatively small amount of air needs to be heated. Furthermore, it is possible to work with high heating temperatures and a high temperature gradient, as a result of which the heating device to be used can be kept comparatively small. At the same time, a high heating temperature can be used for heating up without the risk of ignition in the dust-free, supplied fresh air.
  • the second heating device is preferably designed as a combustion heater, in particular as a fluid burner.
  • the fluid heated or fired in the process is preferably fuel gas, in particular natural gas, or a fuel liquid, in particular crude oil or crude oil derivatives (gasoline, diesel, heating oil) or biofuels.
  • the first and the second heating device can advantageously also be designed as a single heating device. Both the recirculated exhaust air and the fresh air supplied are then heated by this heating device before they are supplied to the upper drying level and passed from top to bottom through the bulk material to be dried there.
  • the lower drying level of the belt drying system according to the invention is preferably divided into several sections and a lower air discharge is provided, by means of which exhaust air is to be guided as supply air from the lower drying level from at least one section to the upper drying level and by means of which furthermore from at least one other section the lower drying level, in particular the fifth to last section in the flow direction of the bulk material to be dried, exhaust air is to be discharged into the environment.
  • exhaust air is to be guided as supply air from the lower drying level from at least one section to the upper drying level and by means of which furthermore from at least one other section the lower drying level, in particular the fifth to last section in the flow direction of the bulk material to be dried, exhaust air is to be discharged into the environment.
  • the exhaust air discharged into the environment advantageously removes moisture from the bulk material to be dried into the environment. This removal of moisture takes place advantageously in that area of the belt drying system according to the invention in which the dust load in the drying air flowing through the bulk material is still comparatively low.
  • the upper drying level is further divided into several sections and an upper air supply is provided, by means of which exhaust air from the lower drying level is to be guided as supply air to at least one section of the upper drying level and by means of which further to at least one other Section of the upper drying level, in particular the fifth section in the flow direction of the bulk material to be dried, fresh air from the environment is to be supplied.
  • an air supply not all of the exhaust air from the lower drying level is returned to the sectioned upper drying level, but part of the supply air for the upper drying level is taken from the environment. This part of the supply air is fed into the middle area of the entire belt drying system, preferably at the fifth section of the upper drying level.
  • the supply air supplied from the environment has only a very low moisture content and a low level of dust and therefore contributes particularly to the drying of the drying bulk material.
  • This supply of comparatively dry supply air is advantageously carried out in that area of the belt drying system according to the invention in which the bulk material to be dried is still comparatively moist and can therefore give off a lot of moisture at a comparatively low temperature.
  • exhaust air is used as supply air from the last section of the lower drying level in the flow direction of the bulk material to be dried to which the first section of the upper drying level is to be conveyed in the direction of flow of the bulk material to be dried.
  • exhaust air from the second to last section of the lower drying level in the flow direction of the bulk material to be dried is to be conveyed as supply air to the second section of the upper drying level in the flow direction of the bulk material to be dried.
  • exhaust air is also to be conveyed from the third from last section of the lower drying level in the flow direction of the bulk material to be dried as supply air to the third section of the upper drying level in the flow direction of the bulk material to be dried, and / or from the fourth from last section of the lower drying level in the flow direction of the bulk material to be dried Drying level to promote exhaust air as supply air to the fourth section of the upper drying level in the direction of flow of the bulk material to be dried.
  • the discharge and supply sectioned in this way has the advantage that in each case very dry air is allocated to the comparatively moist bulk material and less dry air is allocated to the comparatively less moist bulk material.
  • the sectioned return of exhaust air as supply air takes place specifically in four sections, which has proven to be surprisingly advantageous with regard to the overall energy situation.
  • a belt drying system 10 for drying bulk material 12 in the form of sawdust is designed with a feed device 14, by means of which the bulk material 12 to be dried is to be distributed on an upper drying belt 16.
  • the upper drying belt 16 is an endless belt, by means of which the bulk material 12 applied to it can be transported largely horizontally from left to right through an upper drying area 18, based on the figure.
  • the upper drying area 18 and the upper drying belt 16 thus form an upper drying level 20 which is used to pre-dry the bulk material 12.
  • the bulk material 12 at the right-hand end of the drying belt 16 reaches a lower drying belt 22 due to its weight and gravity.
  • This drying belt 22 extends, based on the figure, from right to left through a lower drying area 24 , whereby a largely horizontal, lower drying plane 26 is formed.
  • the lower drying level 26 serves to post-dry the bulk material 12.
  • the subsequently dried bulk material 12 passes out of the belt drying system 10 by means of a discharge device 28.
  • the upper drying level 20 is divided into five sections 30, 32, 34, 36 and 38, which are successively traversed by the bulk material 12 and of which, accordingly, section 30 has a first upper section, section 32 a second upper section, section 34 a third upper section, section 36 forming a fourth upper section and section 38 forming a fifth upper section.
  • the sections 30, 32, 34, 36 and 38 are separated from one another in such a way that the bulk material 12 can pass through them on the upper drying belt 16, but are otherwise largely separated from one another. This separation applies in particular to warm air which is passed through the bulk material 12 in the sections in order to dry it, as will be explained in more detail below.
  • the lower drying level 26 is also divided into five sections, namely sections 40, 42, 44, 46 and 48. Of these sections, section 40 forms a first lower or fifth from last section, section 42 a second lower or fourth from last section , section 44 a third lower or third from last section, section 46 a fourth lower or second from last section and section 48 a fifth lower or last section.

  • section 42 a second lower or fourth from last section
  • section 44 a third lower or third from last section
  • section 46 a fourth lower or second from last section and section 48 a fifth lower or last section.
  • the order of the sections 30, 32, 34, 36, 38, 40, 42, 44, 46 and 48 relate to a flow direction 50 of the bulk material 12 to be dried on the upper drying level 20 and the lower drying level 26.
