Abstract
The utility model relates to a throttling arrangement of many boxes bag collector, including manual valve, box and intake pipe, a plurality of box fixed connection become the dust remover unit, through intake-tube connection between two symmetry dust remover units, all install manual valve in the intake pipe of every box, all be equipped with throttling arrangement at every box gas outlet. The utility model discloses the amount of wind deviation that gets into each box is steerable below 5%, can effectively reduce the whole loss of pressure of dust remover, improves dust collection efficiency simultaneously.
Description
Technical Field
The utility model belongs to the technical field of the environmental protection and specifically relates to a throttling arrangement of many box bag collector is related to.
Background
The bag type dust collector is the main equipment for treating dust pollution at present, and the dust collection effect and the operation cost are directly influenced by the performance of the bag type dust collector.
The conventional multi-box bag type dust collector comprises a dust hopper, a dust air chamber, a filter bag, a pattern plate, an air purifying chamber, a dust cleaning device, an air inlet pipe, manual valves of box inlets and the like, wherein the dust-containing gas enters each box from the air inlet pipe and is filtered after passing through the manual valves of the box inlets, and the clean gas is discharged out of the dust collector from the air purifying chambers of the boxes.
The inlet calibers and the outlet calibers of all the boxes of the conventional multi-box bag type dust collector are the same at present, and due to the structural characteristics of the multi-box bag type dust collector, the air volume difference of the boxes is large, the air volume of the box in the middle basically reaches the average value of the air volume of each box, but the air volume of the box close to the total air inlet is greatly lower than the average value, and the air volume of the box close to the total air outlet is greatly higher than the average value. Therefore, the pressure loss and the dust removal efficiency of each box body are greatly different, and the pressure loss and the outlet dust concentration of the dust remover are integrally improved.
The main functions of each box inlet manual valve of the multi-box bag type dust collector are as follows: the filter bag can be replaced on line after the valve is closed and the off-line valves at the outlets of the box bodies are closed. The inlet and outlet valves of each box body have the air volume adjusting function, but the valve opening degree is not easy to determine and maintain in actual operation, so that the dust remover does not appear in the market until now.
Disclosure of Invention
The utility model aims at overcoming the not enough above, provide a throttling arrangement of many boxes bag collector, get into the amount of wind of each box, speed deviation is steerable below 5%, can effectively reduce the whole loss of pressure of dust remover, improves dust collection efficiency simultaneously.
The purpose of the utility model is realized through the following technical scheme: the utility model provides a throttling arrangement of many boxes bag collector, includes hand valve, box and intake pipe, and a plurality of box fixed connection become the dust remover unit, through the intake-tube connection between two symmetry dust remover units, all installs hand valve in the intake pipe of every box, all is equipped with throttling arrangement at every box gas outlet.
The utility model discloses a further improvement lies in: the throttling device is a pore plate which is made of a steel plate.
The utility model discloses a further improvement lies in: along the total flow direction of the dust-containing gas, the aperture of the pore plate in each box body is gradually reduced.
The utility model discloses a further improvement lies in: the throttling device is welded on the inner wall of the box body air outlet pipe.
Compared with the prior art, the utility model the advantage that has do: firstly, the air quantity entering each box body is basically uniform, and the speed deviation can be controlled below +/-5%. Secondly, after the air volume entering each box body is basically uniform, the load of each filter bag can be basically uniform, thereby effectively reducing the whole pressure loss of the dust remover and simultaneously improving the dust removal efficiency of all the filter bags.
Description of the drawings:
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural diagram of the throttling device.
Reference numbers in the figures: 1-manual valve; 2-a box body; 3-a throttling device; 4-air inlet pipe.
The specific implementation mode is as follows:
in order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
Fig. 1-2 show an embodiment of the throttling device of the multi-box bag-type dust collector of the present invention: including hand valve 1, box 2 and intake pipe 4, a plurality of box 2 fixed connection become the dust remover unit, connect through intake pipe 4 between two symmetry dust remover units, all install hand valve 1 on the intake pipe 4 of every box 2, all be equipped with throttling arrangement 3 in 2 gas outlets of every box. The throttling device 3 is a pore plate which is made of a steel plate; in the flowing direction of the dust-containing gas, the aperture of the pore plate at the air outlet of each box body 2 is gradually reduced; the throttling device 3 is welded on the inner wall of the box body 2.
When the dust-containing gas passes through the air inlet pipe 4 and the manual valve 1 and enters each box body 2, the throttling device 3 is additionally arranged, so that the air quantity entering each box body 2 is basically uniform.
The utility model discloses the amount of wind that gets into each box is even basically, and speed deviation is steerable below 5%, gets into the amount of wind of each box even back basically, can make each filter bag load even basically to can effectively reduce the whole loss of pressure of dust remover, improve the dust collection efficiency of all filter bags simultaneously.
The applicant further states that the present invention is described by the above embodiments, but the present invention is not limited to the above embodiments, i.e. the present invention is not limited to the above embodiments, and the present invention can be implemented only by relying on the above methods and structures. It should be clear to those skilled in the art that any improvement of the present invention is to the present invention, and the addition of the equivalent replacement of the implementation method and the steps, the selection of the specific mode, etc. all fall within the protection scope and the disclosure scope of the present invention.
The utility model discloses not limited to above-mentioned embodiment, all adopt and the utility model discloses similar structure and method realize the utility model discloses all modes of purpose all are within the protection scope of the utility model.
