Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of flue gas purification, and in particular relates to a water seal device for adsorption purification. Background Art
[0002] The smoke from the coking plant's coal loading and coke pushing, and the coke-side furnace head passes through the capture hood and dust removal duct, enters the bag dust collector for purification, enters the fan and muffler, and is discharged into the atmosphere through the chimney.
[0003] The coal loading and coke pushing of the coke oven and the flue gas dust removal on the coke side are characterized by high smoke dust temperature, intermittent emission and multiple emission points. At the same time, the dust source is not fixed and the generation point moves along the track with the coke blocking car and coke pushing car.
[0004] The water-sealed trough technology has a low air leakage rate, a simple structure, and requires little daily maintenance. Therefore, the coking coke side and coke pushing dust removal often adopt the process technology route of water-sealed trough + dust removal ground station.
[0005] The flue gas collected during coal loading and coke pushing and on the coke side contains more tar and has a higher temperature. In order to ensure the service life of the filter bags and prevent the filter bags from being damaged by tar sticking or high temperature, it is usually necessary to install a spark arrester, pre-spraying device or other independent devices.
[0006] However, in actual projects, it is often impossible to set up an adsorption device separately due to site limitations, so it is very necessary to transform the original water seal tank.
[0007] Moreover, installing an adsorption device in the original water seal tank can significantly reduce the project cost and save project investment. Summary of the invention
[0008] The utility model aims to provide a water seal device for adsorption purification in view of the shortcomings of the pretreatment process in the existing coking dust removal.
[0009] The technical solution of the utility model is: a water seal device for adsorption purification, comprising a water channel trough body and an air channel trough body, the water channel trough body and the air channel trough body are welded into a whole, the water channel trough body is placed on a slide rail, a movable support is arranged at the lower part of the slide rail, and a pier is arranged at the lower part of the movable support; the movable support and the pier are connected by bolts; a U-shaped elbow is arranged inside the water channel trough body, and coke particles and coke particle chutes are arranged inside the air channel trough body; the U-shaped elbow is fixed to the pipeline on the coke pushing car or the coke intercepting car through a flange connection; the pipeline trough body is inserted into the U-shaped elbow, the pipeline trough body is a closed space surrounded by plates and water, the water channel trough body and the air channel trough body are connected through the pipeline trough body, and the U-shaped elbow is used to introduce the collected flue gas into the air channel trough body.
[0010] According to an embodiment of the utility model, three layers of coke particles and coke particle chutes are arranged inside the airway trough body, and the coke particles and coke particle chutes are connected to the airway trough body through a chute, and the chute can be pulled out from the side of the airway trough body.
[0011] According to an embodiment of the utility model, a mesh cover is arranged above the coke particles and the coke particle chute, and the coke particles and the coke particle chute are connected to the mesh cover by snap-fitting.
[0012] According to the embodiment of the utility model, a sewage hopper is welded below the waterway trough body; a drain valve is connected below the sewage hopper; an airway drain valve is connected below the airway trough body through a pipeline; the drain valve and the airway drain valve are connected to the drain pipe through a flange.
[0013] The coke particles and coke particle chutes are arranged in plurality along the coke oven direction, and supports are provided between the chutes to ensure the strength of the airway trough body.
[0014] A mesh cover is arranged above the coke particles and the coke particle chute, and large coke particles are built in between the two and connected by snap-fits; the large coke particles are spread flat on the chute; tar and dust collide with, are filtered and adsorbed by the large coke particles, and are retained in the honeycomb holes on the surface of the coke particles and the micropores inside the particles, thereby achieving the purpose of adsorbing and purifying the flue gas.
[0015] The coke particle chute can be pulled out from the side of the chute body, and the maintenance personnel only need to open the buckle to take out the mesh cover, thereby realizing the function of regularly replacing the coke particles to maintain the activity of the coke particles and ensure the adsorption effect of the adsorption layer.
[0016] The utility model changes the structure of the water sealing device tank body, adds a coke particle adsorption layer inside the water sealing tank, and replaces the pre-spraying device or adsorption device that needs to be separately set in the original process, thereby achieving the purpose of adsorbing tar impurities and purifying flue gas.
[0017] And because the added adsorption layer uses coke particles with small specific surface area and developed pore size, it can greatly improve its adsorption effect, reduce the tar content in the flue gas, and reduce the risk of bag filter bag sticking in the subsequent dust removal process.
[0018] Moreover, since the original separate adsorption equipment is cancelled and only the air duct of the water seal tank is modified, the project land can be saved, the project cost can be greatly reduced, and the project investment can be saved.
[0019] The utility model has the advantages of being simple and practical. Compared with the traditional water seal device, it has high adsorption efficiency, does not increase the floor space, and is more economical. Only by changing the structure of the airway tank body and adding a coke particle adsorption layer in the airway tank body, the dust and tar in the flue gas are separated from the flue gas, so as to achieve the effect of pre-treatment of the flue gas; at the same time, the water seal device can replace the independent adsorption device in the original process, reduce the project area and reduce the project cost.
