Abstract

The utility model relates to a diameter-variable cover of an activated carbon fixed bed. The diameter-variable cover is of a square barrel structure the lower part of which is coaxial and diameter-variable. The diameter-variable cover comprises a straight barrel section and a diameter-variable barrel section, wherein the straight barrel section arranged at the upper section and the diameter-variable barrel section arranged at the lower part form the diameter-variable cover. The diameter-variable cover is characterized in that a uniform distribution plate is horizontally fixed to the part of the straight barrel section, which is combined with the diameter-variable barrel section, the uniform distribution plate is a middle replicate plate, and multiple through holes are uniformly formed in the plate surface of the uniform distribution plate at interval. The diameter-variable cover provided by the utility model has the advantages that a diameter-variable section of the diameter-variable cover is fixedly provided with a cone-shaped uniform distribution plate, the multiple through holes are uniformly formed in the uniform distribution plate at interval, so that the airflow which enters the activated carbon fixed bed is uniformly distributed in advance and is buffered, a condition that the airflow which comes from a pipeline directly scours the activated carbon is avoided, the service life of the equipment core piece activated carbon is greatly prolonged, the secondary pollution of the activated carbon dust is reduced, and meanwhile, the economic and environment-friendly double doubles are achieved.

Description

A kind of reducing cover of activated carbon and fixed bed

Technical field

The utility model relates to the waste gas purification stage of VOCs charcoal absorption catalytic combustion device, especially a kind of reducing cover of activated carbon and fixed bed.

Background technology

The waste gas purification stage in VOCs charcoal absorption catalytic combustion device, waste gas is because air-flow layout is inhomogeneous, huge to the active carbon scouring force in activated carbon and fixed bed, makes active carbon powder and enters in atmosphere with air-flow, form dust pollution, greatly reduced the service life of active carbon.Tracing it to its cause, is exactly that fixed bed air-flow directly washes away active carbon, causes active carbon powder, has reduced thus the service life of active carbon.

It is equal that utility model content is unkitted air-flow

The purpose of this utility model is to overcome the deficiency existing in above-mentioned technology, and a kind of reducing cover that improves the absorption efficiency of active carbon and the activated carbon and fixed bed in service life is provided.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of reducing cover of activated carbon and fixed bed, for the square cartridge structure of the coaxial reducing in bottom, comprise direct tube section and reducing cylinder section, the reducing cylinder section of the direct tube section of epimere and bottom forms reducing cover, it is characterized in that: with the direct tube section of reducing cylinder section binding site on be laterally fixedly mounted with a uniform board, this uniform board is middle deflector, and on the plate face of uniform board, uniform interval is shaped with multiple through holes.

And the angle of turning back of described uniform board is 150-180 °.

Advantage of the present utility model and beneficial effect are:

1, on the reducer of this reducing cover reducing cover, be fixedly mounted with a taper uniform board, on uniform board, uniform interval is shaped with multiple through holes, the air-flow that enters activated carbon and fixed bed is uniformly distributed in advance, obtain a buffering at this air-flow, avoid directly washing away active carbon by pipeline air-flow out, in the service life of greatly having improved device core part active carbon, reduced the secondary pollution of active carbon dust, reached economy and environmental protection economic benefits and social benefits benefit simultaneously.

2, this reducing cover has been realized air-flow after the through hole of uniform board, can, equably by charcoal absorption, improve the adsorption efficiency of active carbon, has also extended the service life of active carbon.

Detailed description of the invention

Below in conjunction with accompanying drawing, by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

A reducing cover for activated carbon and fixed bed, is the square cartridge structure of the coaxial reducing in bottom, comprises direct tube section 1 and reducing cylinder section 3, and the reducing cylinder section of the direct tube section of epimere and bottom forms reducing cover.

Innovative point of the present utility model is:

With the direct tube section of reducing cylinder section binding site on be laterally fixedly mounted with a uniform board 2, this uniform board is the middle deflector of inverted V-shaped, on the plate face of uniform board, uniform interval is shaped with multiple through holes 4, makes thus vapor stream on uniform board, carry out current stabilization, and evenly upwards carries.

The angle of turning back of uniform board is 150-180 °, and visual concrete condition is carried out angle initialization.

Claims

1. the reducing cover of an activated carbon and fixed bed, for the square cartridge structure of the coaxial reducing in bottom, comprise direct tube section and reducing cylinder section, the reducing cylinder section of the direct tube section of epimere and bottom forms reducing cover, it is characterized in that: with the direct tube section of reducing cylinder section binding site on be laterally fixedly mounted with a uniform board, this uniform board is middle deflector, and on the plate face of uniform board, uniform interval is shaped with multiple through holes.

2. the reducing cover of activated carbon and fixed bed according to claim 1, is characterized in that: the angle of turning back of described uniform board is 150-180 °.
