Abstract

The utility model provides a single side air intake type online pulse cleaning bag deduster which is characterized by comprising a lower box. A filter bag dedusting area formed by arranging filter bags is disposed in the lower box. An upper box is disposed at the top of the lower box. A dust hopper is disposed at the bottom of the lower box. A gas inlet flue is arranged on the sidewall on one side of the lower box and completely covers the sidewall. A gas inlet uniform distribution plate is disposed on the connection of the air inlet flue and the lower box. A dust hopper backmixing preventing device is disposed on the connection of the lower box and the dust hopper. A non-equant spray pipe is disposed in the upper box. One end of the non-equant spray pipe is connected with an air pocket. A plurality of spray nozzles are formed at the other end of the non-equant spray pipe. Each spray nozzle corresponds to a filter bag in the filter bag dedusting area. An exhaust flue is arranged on the upper box. Flues are disposed on one side of the deduster, flue gases enters the filter area through the gas inlet uniform distribution plate from the outer side of the lower box of the deduster, area of air intake is as large as the whole lower box side wall, and accordingly air intake speed is lowered evidently and dust cleaning resistance is reduced.

Description

A kind of one-sided side air admission type line pulse deashing sack cleaner

Technical field

The utility model relates to a kind of one-sided side air admission type line pulse deashing sack cleaner, belongs to the bag type dust removing technology field.

Background technology

At present; The sack cleaner that heating boiler uses is the ash bucket intake method; This structure under the higher operating mode of import wind speed during deashing dust be difficult to be deposited in and form the secondary back-mixing in the ash bucket, make the dust that comes off behind the deashing return the filter bag surface again, cause the deduster running resistance bigger.

Summary of the invention

The purpose of the utility model provides a kind of one-sided side air admission type line pulse deashing sack cleaner, adopts the method that increases dusty gas import air channel area, changes the air current flow mode, reduces the import wind speed, strengthens ash-removal effect, reduces running resistance.

In order to achieve the above object, the technical scheme of the utility model has provided a kind of one-sided side air admission type line pulse deashing sack cleaner, it is characterized in that: comprise lower box; In lower box, be provided with by filter bag and arrange the filter bag dedusting area that forms, be respectively equipped with upper box and ash bucket, on upper box, be provided with exhaust uptake in the top and the bottom of lower box; On the sidewall of lower box one side, be provided with the air inlet flue; The air inlet flue covers this sidewall fully, is provided with the air inlet uniform board in the junction of air inlet flue and lower box, is provided with the anti-back-mixing device of ash bucket in the junction of lower box and ash bucket; In upper box, be provided with non-isometrical winding-up pipe; One end of non-isometrical winding-up pipe connects gas bag, and its other end is formed with a plurality of winding-ups mouths, filter bag in each winding-up mouthful corresponding filter bag dedusting area.

Preferably, be provided with at the top of said upper box and take off cover plate.

Preferably, below said each winding-up mouth, be provided with the filter bag protective device.

Preferably, gradient base plate is adopted in the bottom of said air inlet flue, and the bottom of air inlet flue communicates with said ash bucket.

The utility model is arranged in a side of deduster with flue, and through air inlet uniform board entering filtering area, air-admitting surface is whole lower box side wall surface to flue gas, makes the import wind speed significantly reduce, and has reduced the deashing resistance from the deduster lower box outside; Sidewall air intake air motion direction is not relative with deashing dust falling direction simultaneously, avoids reentrainment of dust; The air inlet flue adopts gradient base plate, is difficult for dust stratification, and the bulky grain dust can get into ash bucket by the set gradient base plate in bottom along base plate and discharge.

The specific embodiment

For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.

Extremely shown in Figure 3 like Fig. 1; A kind of one-sided side air admission type line pulse deashing sack cleaner that the utility model provides; Comprise lower box 10, in lower box 10, be provided with by filter bag 9 and arrange the filter bag dedusting area that forms, be respectively equipped with upper box 12 and ash bucket 11 in the top and the bottom of lower box 10.On the sidewall of lower box 10 1 sides, be provided with air inlet flue 1, air inlet flue 1 covers this sidewall fully, and gradient base plate is adopted in the bottom of air inlet flue 1, and the bottom of air inlet flue 1 communicates with said ash bucket 11.Junction at air inlet flue 1 and lower box 10 is provided with air inlet uniform board 2, is provided with the anti-back-mixing device 3 of ash bucket in the junction of lower box 10 and ash bucket 11.Be provided with at the top of upper box 12 and take off cover plate 5; In upper box 12, be provided with non-isometrical winding-up pipe 8; One end of non-isometrical winding-up pipe 8 connects gas bag 6, and its other end is formed with a plurality of winding-ups mouths, filter bag 9 in each winding-up mouthful corresponding filter bag dedusting area; Below each winding-up mouth, be provided with filter bag protective device 7, on upper box 12, also be provided with exhaust uptake 4.

During work, ash-laden gas gets into deduster by air inlet flue 1, and flue gas passes in and out filter bag zone 9 and carries out dust-filtering after 2 uniform distributions of air inlet uniform board, and the clean gas after the filtration is discharged from exhaust uptake 4 through upper box 12.The dust that accumulates in the filter bag dedusting area forms air wave through winding-up pipe 8 jet gas comes off filter bag 9 rapid expansions and impact shock; Dropping, dust is stoped by the anti-back-mixing device 3 of ash bucket after forming the secondary back-mixing in ash bucket 11, prevents that it from getting into filter bag dedusting area 9 once more.
