Abstract
Description
Technical Field
[0001] The invention relates to the technical field of catalyst recovery, and in particular to a brush-type SCR flat-plate denitration catalyst powder removal device. Background Art
[0002] Currently, plate-type catalysts become ineffective after being used for a period of time and need to be regenerated or disposed of. However, catalysts that are severely worn and powdered due to erosion by the boiler wind field cannot be regenerated. These non-regenerable catalysts need to have their powders peeled off from the mesh and then purified. However, separation of powders from meshes has always been a problem, so equipment that can separate powders from meshes is needed. Summary of the invention
[0003] The technical problem to be solved by the present invention is to provide a brush-type SCR flat-plate denitration catalyst powder removal device in view of the above-mentioned technical deficiencies. The non-regenerative plate catalyst is separated from the powder and mesh by mechanical means. This disposal method is a purely mechanical separation method. No reagent is added when separating the powder and mesh, and no secondary pollution is caused to the environment. The collected powder can be refined again to make new catalyst for recycling, and the iron mesh produced can be sold to steel mills to achieve the purpose of recycling.
[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: it includes a frame, a feed belt installed on the left side of the upper part of the frame, a discharge belt installed on the right side of the upper part of the frame, a flattening shaft installed in the center of the upper part of the frame and close to the feed belt side, a brush shaft installed on the frame close to the discharge belt side, and a drag shaft installed on the upper part of the frame and directly below the brush shaft.
[0005] To further optimize the technical solution, a blocking belt is provided on the upper part of the frame, above the discharging belt, and close to the brush shaft.
[0006] To further optimize the technical solution, an ash receiving hopper is provided at the lower part of the frame, between the feed belt and the discharge belt.
[0007] To further optimize the technical solution, the feed belt, discharging belt, flattening shaft and blocking belt are jointly driven by a reduction motor using a chain; the power of the reduction motor is 0.75KW; the conveying speed of the feed belt and the flattening shaft is 50-150mm / s.
[0008] To further optimize the technical solution, the brush shaft is dragged by a 2-stage 5.5KW motor relying on two B-type V-belts and is decelerated by a pulley; the brush shaft rotates at a speed of 1500r / min.
[0009] To further optimize the technical solution, the steps are as follows: manually remove the mesh with powder in the denitrification catalyst with the help of auxiliary tools, and then put the mesh with powder on the upper part of the feed belt at the machine inlet, and the feed belt will transport the mesh to the inside of the machine. The machine first flattens the mesh from the feed belt with two flattening shafts. After passing through the flattening shaft, the mesh will reach the brush shaft. The brush shaft is responsible for brushing the powder on the mesh. Part of the powder falls into the ash hopper at the bottom of the frame by gravity, and the other part of the powder is sucked away and collected by the bag dust collector. The mesh with the powder brushed off slides to the discharge belt through the brush force applied by the brush shaft and the support of the drag shaft. Since the brush force applied by the brush shaft is large, the mesh is prevented from flying by blocking the installation of the belt; the separated powder will be purified or sold, and the mesh will be packaged and sold to the steel plant, thereby realizing the recycling and reuse of the denitrification catalyst.
[0010] Compared with the prior art, the present invention has the following advantages: the patent of the present invention is to separate the powder from the mesh of the non-regenerable plate catalyst by mechanical means. This disposal method is a purely mechanical separation method. No reagent is added when separating the powder from the mesh, and no secondary pollution is caused to the environment. The collected powder can be refined again to make new catalyst for recycling, and the iron mesh produced can be sold to steel mills to achieve the purpose of recycling.

The machine first flattens the mesh from the feed belt 2 by two flattening shafts 4. After passing through the flattening shaft 4, the mesh will reach the brush shaft 5.
