Description

Ash cleaning treatment workshop for SCR denitrification catalyst

technical field

The utility model relates to a dust removal treatment workshop of an SCR denitrification catalyst.

Background technique

During the use of SCR denitrification catalyst in the power plant, due to the process of the power plant, the denitrification process is before dust removal, which makes the SCR denitrification catalyst in the process of use, the catalyst unit (unit box) channel and between the unit body (unit box) will be a lot However, during the regeneration process of the SCR denitration catalyst, the fly ash must not be brought into the regeneration system of the SCR denitration catalyst. The ash inside the catalyst and between the gaps between the unit cells is removed.

Utility model content

The purpose of the utility model is to provide a deashing treatment workshop for SCR denitration catalyst, which can collect fly ash and fly ash produced by deashing treatment of SCR denitration catalyst.

In order to achieve the above object, the technical solution of the utility model is to design a kind of SCR denitrification catalyst cleaning treatment workshop, including:

cleaning room,

The air induction pipe connected through the ash cleaning treatment room,

The cyclone dust collector, bag dust collector and induced draft fan arranged on the induced draft pipe in turn,

The ash collection pit excavated on the ground of the ash cleaning treatment room,

screens on the top of the ash pit,

And the screw conveyor connected through the ash collection pit;

The cyclone dust collector is located between the dust removal treatment chamber and the bag dust collector.

Preferably, the air induction pipe is connected through the top of the ash removal treatment chamber.

Preferably, the feeding end of the screw conveyor is connected through the upper part of the ash collection pit.

Preferably, a stirring device is provided in the ash collecting pit.

Preferably, the stirring device includes: a vertical stirring shaft, and a stirring frame fixed on the stirring shaft.

The utility model has the advantages and beneficial effects of providing a deashing treatment workshop for an SCR denitration catalyst, which can collect fly ash and fly ash produced by the deashing treatment of the SCR denitration catalyst.

The SCR denitrification catalyst is first transported by a forklift to the ash removal treatment workshop, and the dust (fly ash) generated during the ash removal treatment process is drawn into the air duct by the induced draft fan, and the fly ash is collected by the cyclone dust collector and the bag filter , There is an ash collection pit excavated on the ground of the ash removal treatment room, and the fly ash that falls on the ground during the ash removal process can enter the ash collection pit, and the screw conveyor will be opened when the amount of ash in the ash collection pit reaches a certain level Collect the fly ash in the ash pit into big bags.

detailed description

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

The technical scheme of the concrete implementation of the utility model is:

As shown in Figure 1, a dedusting treatment workshop for SCR denitrification catalysts includes:

Cleaning chamber 1,

The air induction pipe 2 connected through the dust removal treatment chamber 1,

The cyclone dust collector 3, the bag filter 4 and the induced draft fan 5 arranged on the induced air pipe 2 in sequence,

The ash collection pit 6 excavated on the ground of the ash removal treatment room 1,

The mesh plate arranged on the top surface of the ash pit 6,

And the screw feeder 7 connected through the ash pit 6;

The cyclone dust collector 3 is located between the dust removal treatment chamber 1 and the bag dust collector 4 .

The air induction pipe 2 is connected through the top of the dust removal treatment chamber 1 .

The feeding end of the screw conveyor 7 is connected through the upper part of the ash collection pit 6 .

A stirring device is provided in the ash collecting pit 6 .

The stirring device includes: a vertical stirring shaft, and a stirring frame fixed on the stirring shaft.

The SCR denitrification catalyst is first transported by a forklift to the ash removal treatment workshop, and the dust (fly ash) generated during the ash removal treatment process is pumped into the air induction pipe 2 by the induced draft fan 5, and the fly ash in it passes through the cyclone dust collector 3 and the cloth bag The dust collector 4 collects, and an ash collection pit 6 is excavated on the ground of the ash removal treatment room 1. The fly ash dropped on the ground during the ash removal process can enter the ash collection pit 6 and wait for the ash collection pit 6 When the amount of internal ash reaches a certain value, the screw feeder 7 is opened to collect the fly ash in the ash collection pit 6 into the big bag.

The above is only the preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made. And retouching should also be regarded as the protection scope of the present utility model.
