Description

High-efficient deashing distributor bag cage

Technical Field

The utility model relates to a fitting of a pulse dust collector.

Background

The working principle of the pulse bag type dust collector is as follows: after the dust-containing flue gas entering the pulse bag type dust collector is filtered by the filter bag, dust adsorbed on the surface of the filter bag is blown by high-pressure air and falls off into the dust hopper. In the original conventional standard pulse bag type dust collector, the venturi tube on the bag cage in the filter bag dust collector is only 100 plus 150 mm, and the venturi tube on the bag cage is designed to be too short, so that two defects are caused: firstly, because the high-pressure air (3-5 MPa) used in the ash removal is frequently blown and the verticality center of the nozzle has deviation, the upper section (100 + 600 mm) of the filter bag is frequently blown, the upper part (below the outlet of the venturi tube) of the filter bag can be blown in about 1-2 months, and the damaged filter bag needs to be replaced in time; secondly, when the length of the venturi tube on the bag cage is too short, a high-pressure air source used for cleaning ash cannot reach the lower part of the bag cage, and the ash on each part of the filter bag cannot be cleaned thoroughly, so that the ash is collected seriously on the upper part and the lower part of the filter bag, the service life of the filter bag is shortened, and the dust removal efficiency is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem who solves: how to design an efficient pulse dust collector bag cage.

The technical scheme of the utility model specifically does:

the utility model provides a high-efficient deashing distributor bag cage, includes netted bag cage, the fixed venturi tube 21 of bag cage upper end, the lower extreme of venturi tube 21 is fixed rather than the equal tuber pipe of UNICOM, and equal tuber pipe sets up along the axis of bag cage, extends to the bottom of bag cage, evenly is equipped with the multilayer on the equal tuber pipe and spouts the wind layer, each spouts the spout of a plurality of radial distributions on wind layer.

The bottom end of the air equalizing pipe is fixed with a plug which can prevent high-pressure gas from being sprayed out from the bottom end of the air equalizing pipe, and the ventilation quantity of the nozzle is increased.

Each air-jet layer is uniformly provided with six or eight nozzles.

Compared with the prior art, the technical effect of the utility model is that, the utility model discloses be close to the venturi tube extension in the bag cage for bag cage length, high-pressure gas blows filter bag bottom in-process from bag cage top, progressively evenly from a plurality of jetting mouth blowout to make the dust of cover on the filter bag of bag cage outside can be blown off more effectively. The phenomenon that the middle part and the lower part of the filter bag are not completely cleaned can be greatly reduced, so that the upper part, the middle part and the lower part of the filter bag have very good dust cleaning effect. The bag breaking frequency of the filter bag is reduced, the service life of the filter bag is naturally prolonged, the running cost of the pulse bag type dust collector is reduced, and the dust collection efficiency is improved.

Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In the present invention, it is noted that relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.

When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Furthermore, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like are used herein to indicate orientations or positional relationships based on the drawings, and are used for convenience in describing the present invention, but do not indicate or imply that the device or element so referred to must have this particular orientation, be operated in a particular orientation configuration, and not be construed as limiting the present invention.

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments thereof.

Referring to fig. 1-2, a bag cage of a high-efficiency ash removal distributor comprises a netted bag cage 20, the bag cage 20 is a framework for supporting a filter bag, a venturi tube 21 is fixed at the upper end of the bag cage 20, an air equalizing pipe 22 communicated with the venturi tube 21 is fixed at the lower end of the venturi tube 21, the air equalizing pipe 22 is arranged along the axis of the bag cage 20 and extends to the bottom of the bag cage 20, a plurality of air injection layers are uniformly arranged on the air equalizing pipe 22, and a plurality of nozzles 23 are radially distributed on each air injection layer.

In order to improve the efficiency, a plug 26 is fixed at the bottom end of the air equalizing pipe 22, and the plug can prevent high-pressure air from being sprayed out from the bottom end of the air equalizing pipe 22, so that the ventilation quantity of the nozzle 23 is increased.

For uniform soot blowing, six or eight nozzles 23 are uniformly provided for each of the blowing levels.

The working principle is as follows:

when in use, as in the prior art, the filter bag is sleeved outside the bag cage 20, the inlet (bell mouth) of the venturi 21 is aligned with the air outlet pipe 11 on the high-pressure air pipe 10, and the bag cage 20 is fixed on the card 12.

Through the control of the pulse valve, the high-pressure gas in the high-pressure gas pipe 10 is intermittently sprayed into the venturi 21 and the air equalizing pipe 22, and then is sprayed into the inner surface of the bag cage 20 from the nozzle 23, so that the dust on the filter bag sleeved outside the bag cage 20 is blown off.

This patent application high-efficient deashing distributor bag cage reforms transform the back and is close to the venturi tube extension in the bag cage for bag cage length, and high-pressure gas blows to filter bag bottom in-process from bag cage top, progressively evenly from the blowout of a plurality of jetting mouth to make the dust of cover on the filter bag of bag cage outside can be blown off more effectively. The phenomenon that the middle part and the lower part of the filter bag are not completely cleaned can be greatly reduced, so that the upper part, the middle part and the lower part of the filter bag have very good dust cleaning effect. The bag breaking frequency of the filter bag is reduced, the service life of the filter bag is naturally prolonged, the running cost of the pulse bag type dust collector is reduced, and the dust collection efficiency is improved.
