Useless denitration catalyst vibrations sweep device

Technical Field

The utility model belongs to denitration catalyst treatment field, specifically speaking relates to a useless denitration catalyst vibrations sweep device.

Background

The denitration catalyst is a catalyst used for a denitration system of a power plant, a reducing agent and nitrogen oxide in smoke are promoted to chemically react at a certain temperature, common denitration catalysts in the market comprise honeycomb type, plate type, corrugated type and other types, wherein the honeycomb type is adopted by most enterprises due to the advantages of large area, high activity, small catalyst volume, more catalytic active substances, reusability and the like.

The denitration catalyst is recycled by removing the deposited ash on the surface of the catalyst and then cleaning the catalyst by using a cleaning solution and an activity supplementing solution.

The flying dust on catalyst surface is blown away to useless denitration catalyst among the prior art adopts compressed air usually, and the device that the comparatively common useless denitration catalyst of being responsible for sweeps the process at present is airtight space at the during operation, and the flying dust can pile up in the device bottom after being blown off denitration catalyst surface, and the dust is piled up too much and can influence the working effect of device, and adopts the manual work to clean comparatively difficult, and the raise dust is big among the clearance process, is unfavorable for staff's healthy.

Therefore, a new design capable of performing a purging work of the spent denitration catalyst and automatically cleaning the fly ash is required.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned problem that prior art exists, the utility model aims to provide a useless denitration catalyst vibrations sweep device.

In order to solve the above problem, the utility model discloses the technical scheme who adopts as follows:

the utility model provides a device is swept in vibrations of useless denitration catalyst, is including sweeping work portion and dust absorption work portion, the work portion that sweeps include the dust removal storehouse, vibrate the bed, sweep the gas pipe, the vibration bed set up in the center part in dust removal storehouse, the one side in dust removal storehouse be equipped with dustproof door, the dust removal storehouse in be equipped with mobilizable sweeping gas pipe, dust absorption work portion including dust removal pipeline and dust shaker, dust removal pipeline set up in dust removal storehouse bottom and link to each other with the dust shaker. Compared with the prior art, the beneficial effects of the utility model are that:

the dust remover is a negative pressure dust collector.

The bottom of the dust removal bin is provided with a cleaning nozzle.

The blowing gas pipe is provided with a plurality of blowing nozzles.

The dustproof door is an electric door.

Dust shaker one side be equipped with the ash hole, the ash hole below is equipped with collects the box.

The vibrating bed is a spring type vibrating screen.

The utility model discloses the work of sweeping of useless denitration catalyst of mainly used, through the vibrations pine of vibrating in the bed with denitration catalyst pore, then blow off the deposition in the pore through sweeping the nozzle, the deposition on clean up denitration catalyst pore surface, then cooperate with the dust removal pipeline that is connected with the negative pressure dust catcher through the clearance nozzle of dust removal storehouse bottom, the deposition that will blow off is collected, then collects to collecting the box from the ash hole of dust shaker. The utility model discloses can carry out automatic collection to the dust of bottom in the dust removal storehouse, prevent piling up the normal work that the bed was vibrated in the influence of dust to saved the link of artifical clearance deposition, reduced operating personnel's work load and also guaranteed that the staff's is healthy simultaneously.

Detailed Description

The present invention will be further described with reference to the following specific embodiments.

As shown in fig. 1 and 2, the present invention mainly includes a blowing operation part and a dust collection operation part.

The main body of the purging working part is a dust removal bin 1, the dust removal bin 1 is designed to be sealed on three sides, a dust-proof door 6 is arranged on the opened side of the dust removal bin 1, and the dust-proof door 6 adopted in the embodiment is an electric door.

The inside two crossbeams that are equipped with of dust removal storehouse 1, the central point of crossbeam puts the department and is equipped with vibrates bed 2, vibrates that bed 2 is built on stilts to be set up in dust removal storehouse 1, vibrates bed 2 in this embodiment for the spring shale shaker, the high dust environment of adaptation during operation that the spring shale shaker can be better. One side that is located dustproof door 6 in the dust removal storehouse 1 is equipped with purge gas pipe 3, and the wall at purge gas pipe 3 both ends is equipped with the removal track that matches with it for purge gas pipe 3 can reciprocate on the track under the control of motor, is equipped with a plurality of nozzles 4 that sweep on purge gas pipe 3 for blow to placing the pending article on shaking bed 2.

The bottom of the dust removal bin 1 is provided with a plurality of cleaning nozzles 5, the cleaning nozzles 5 are only arranged on one side of the left and right connected surfaces of the open surface of the dust removal bin 1, and the bottom of the surface on the opposite side of the cleaning nozzles 5 is provided with a dust removal pipeline 7.

Dust absorption work portion includes dust shaker 8 and dust removal pipeline 7, and the one end of dust removal pipeline 8 links to each other with dust removal storehouse 1 is inside, and the other end directly links to each other with dust remover 8, and dust shaker 8 in this embodiment is the negative pressure dust catcher. The cross section of the dust removal pipeline 7 is a rectangular pipeline, the length of the pipeline is slightly smaller than the width of the side face of the dust removal bin 1, and dust deposited at the bottom of the dust removal bin 1 can be better sucked.

The side of the dust remover 8 is provided with an ash outlet 9 for dust collection, and a movable collecting box 10 is arranged below the ash outlet 9.

Operating personnel uses the utility model discloses the time, earlier open electronic dust damper 6, then place useless denitration catalyst and vibrate bed 2 on, the pore of guaranteeing denitration catalyst this moment closes dust damper 6 towards the direction of sweeping gas pipe 3 after placing the completion. The bed 2 and the pipeline 3 that sweeps are shaken in the start-up, vibrate bed 2 and shake loosely, shake the deposition in the pore, sweep pipeline 3 and then reciprocate under the control of motor, sweep useless denitration catalyst through sweeping nozzle 4 and continuously sweep. Vibrate bed 2 and sweep nozzle 4 stop work after the work of sweeping is accomplished, clearance nozzle 5 and dust shaker 8 begin work, and the deposition that clearance nozzle 5 will blow down is inhaled in dust shaker 8, because vibrate the built on stilts setting on the crossbeam of bed 2, the effect of dust absorption is better. Then, the deposited dust is output from an ash outlet 9 on the side surface of the dust remover 8 and falls into a collecting box 10 to finish the collection of the deposited dust.
