Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a new dry desulfurization tower used for desulfurization of fuel gas and the like.

(Prior art) Generally, there are two types of dry desulfurization equipment for gas: box type and tower type. Among these, the tower type is filled with pellet-like desulfurizing agent and powdered desulfurizing agent. Some types are filled with desulfurizing agents in multiple stages. The present invention is directed to the latter dry desulfurization tower that uses a powdered desulfurization agent.

Conventionally, in the case of using this type of powder desulfurization agent, several layers of porcelain plates were laid inside the tower, and then
There was one in which the desulfurizing agent was placed in a 150 to 450 mm thick box, and another in which the desulfurizing agent was packed in a cylindrical box.

(Problems to be solved by the invention) However, among the conventional devices, first of all, in the case of the former type of oxidation plate, when replacing the used desulfurizing agent with a new one, the operator must The odor is so bad that the work environment is extremely poor, and the work must be continued only after the odor has been sufficiently purged using steam, etc. It was almost impossible to do so, and wearing an airline mask or the like to protect against odors was not appropriate as it significantly impeded work efficiency. In addition, in the case of cylindrical boxes that are stacked in multiple tiers, the rubber used for sealing tends to deteriorate, and it is essential to have a large crane on hand to move them for refilling, etc. It was unsuitable for the desulfurization tower.

The object of the present invention is to provide a desulfurization tower that eliminates the above-mentioned drawbacks.

(Means for solving the problems) The present invention employs the following means to solve the above problems. That is, a. The present invention forms a desulfurizing agent chamber for storing a desulfurizing agent inside a cylindrical and closed column main body, and an inlet for unpurified gas and an outlet for purified gas are attached to the outer surface of the side plate of the main body. b. The desulfurizing agent chamber is divided into a plurality of fan-shaped compartments radially extending from the support center toward the main body side plate, and c. Each fan-shaped compartment is provided with external mechanical lifting means. A fan-shaped box-shaped tray that can be lifted or suspended is accommodated, and each tray is arranged so that a gap is created between the outer surface of each tray, the outer wall surface of the adjacent tray, the inner surface of the side wall of the tower main body, and the outer peripheral surface of the support center. The gist is that the same desulfurizing agent as the desulfurizing agent stored in each tray is filled in the gaps between the trays.

(Example) The present invention will be described below based on an example with reference to the drawings.

FIG. 1 is a partially cutaway plan view of the top of the dry desulfurization tower according to the present invention, showing the tower main body viewed from above.

The tower main body 1 has a cylindrical shape and is covered by a tower top part 1a which can be removed and attached, and is in a sealed state when in use. Inside is a desulfurization agent chamber 2 that stores the desulfurization agent.
is formed. The outer surface of the side plate 3 of the main body is provided with inlets 4a, 4b for unrefined gas, and outlet ports 5a, 5b for purified gas on the opposite side. A support center 6 is established in the center of the desulfurization agent chamber 2, extending from the bottom of the main body (not shown) to the tower top 1a.

In the desulfurization tower of the present invention, the desulfurization agent chamber 2 is divided into a plurality of fan-shaped sections 7, 7, . . . radially extending from the support center 6 toward the main body side plate 3. The division is usually preferably 6 to 16 pieces. In each sector,
A tray 8 as shown in FIG. 2(i), which can be lifted and hung by an external mechanical hanging means such as a racker, houses a desulfurizing agent 9. The tray 8 is provided with an appropriate support member 1 between the support center 6 and the side plate 3.
3 and 14 (see Figure 2(ii)).

Next, in the present invention, each tray is formed so that a gap 10 is created between the outer wall surface of the tray 8 and the outer wall surface of the adjacent tray, as shown in FIG. 2(ii). The gap is preferably about 20 to 300 mm. Also,
As shown in FIG. 3(iii), each tray is formed so that a similar gap is created between the tower main body side plate 3 and the outer circumferential surface of the center pole 6, respectively. This is a characteristic part of the tray according to the present invention, and each gap 10 is filled with a desulfurizing agent 9 as a sealing material. Reference numeral 15 indicates a receiving plate for a desulfurizing agent for sealing material.
The desulfurization agent used as the sealing material is the same as that stored in each tray.

In the desulfurization tower according to the present invention, the inlet 4a or 4b
Unrefined gas flowing from either of the gas distribution chambers 11a or 11b (not shown) built into the main body flows into the desulfurization agent chamber 2 and is desulfurized, and then passes through the slits (not shown) of the gas distribution chambers 12a or 12b. 5) and flows out from either the outlet 5a or 5b.

(Effects of the invention) The present invention is based on the above configuration, and the desulfurizing agent chamber is divided into a plurality of fan-shaped compartments, and the fan-shaped box-shaped tray is accommodated in each compartment.
When refilling the desulfurizing agent, it can be easily lifted or suspended using external mechanical lifting means such as a retcher, and it is also possible to fill the tray with desulfurizing agent outside the tower, improving work efficiency. In addition, each tray is formed so that a gap is created between the outer wall surface of each tray, the outer wall surface of the adjacent tray, the inner surface of the side plate of the tower body, and the outer peripheral surface of the support center, and this portion is also filled with the same desulfurizing agent. Therefore, the raw material gas that enters the desulfurization tower always comes into contact with the desulfurization agent.
It has many advantages such as not causing the inconvenience of being discharged from the outlet without being desulfurized, and in particular, it is an extremely useful device because it easily allows a large-capacity desulfurization tower to be constructed.
