Description

Pulsed jet cloth filter
Technical field
This utility model relates to exhaust gas dust processing technology field, is specifically related to a kind of pulsed jet cloth filter.
Background technology
Application publication number is that the patent of CN 104324578 A discloses a kind of sack cleaner, including: frame, it is arranged on Air inlet on frame side and the escape pipe being arranged on frame upper end, be provided with sack cleaner in frame, remove at cloth bag The lower end of dirt device is provided with bag-type dust ash bucket, the upper end of sack cleaner is provided with cloth bag dust-removing lifting valve, removes at cloth bag Being provided with air-purifying chamber in the frame of dirt device upper end, air-purifying chamber is connected with escape pipe, and the frame above sack cleaner sets It is equipped with the blowing device mutual with it, the frame of described sack cleaner front end is provided with electric cleaner.
Along with the increase of filtration working time, dust layer progressive additive outside filter bag, the resistance of dust pelletizing system the most gradually adds Greatly, now, cleaner unit need to carry out reverse gas cleaning, after this room completes deashing work, when need to open lifting valve, due to now dedusting The resistance of system is big, and cylinder needs the compressed air of very high pressure just can open, and otherwise promotes valve and does not opens, makes this room to enter Enter and filter duty normally.
Utility model content
The technical problems to be solved in the utility model is to provide the pulsed jet cloth filter that a kind of convenient lifting valve is opened, bag Including casing, support and pulse dust cleaning system, be provided with multiple filter bag in casing, casing is arranged on support, is provided with many below casing Individual ash bucket, is provided with multiple dividing plate that casing is divided into independent filter chamber in casing, filter chamber is provided above a total clean gas Room, the outlet of air-purifying chamber is arranged on casing, and the corresponding ash bucket in each filter chamber, each independent filter chamber is arranged over leading to Disconnected air-purifying chamber and the lifting valve of filter chamber, gas approach is arranged on casing, gas approach by bronchial connect each solely Ash bucket below vertical filter chamber, bronchial is provided with flue gas stop valve.
After being provided with flue gas stop valve at the gas approach of each bin, before deashing, first close flue gas stop valve, make whole Individual filtration bin and air-purifying chamber are under same negative pressure state, so that the on an off promoting valve need not bigger thrust and draws Power, protects cylinder.
As further improvement of the utility model, described filter chamber is additionally provided with a relief valve, and relief valve can after opening So that air-purifying chamber keeps identical with the air pressure of filter chamber.
Further, active carbon powder pay-off, described active carbon powder pay-off it are provided with at described gas approach Discharging opening connection gas approach.A small amount of activity he can carry out filtering area, adsorbing subsequently on filter bag surface with flue gas by powder, Active carbon powder now and flue gas are in the contact area of maximum, can active adsorption two English, when accumulating a certain amount of, activity After reduction, the activated carbon on cloth bag surface can be removed by soot cleaning system, and postorder is by activated carbon new for absorption.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
As depicted in figs. 1 and 2, sack cleaner one pulsed jet cloth filter of the present utility model, including casing 14, props up Frame and pulse dust cleaning system, soot cleaning system includes winding-up gas bag, electromagnetic impulse valve and the peace being arranged in the rain insensitive device of top The winding-up pipeline etc. being contained in upper box, is provided with multiple filter bag 5 in casing 14, casing 14 is arranged on support, sets below casing Having multiple ash bucket 2, each ash bucket is provided with a shake motor 1, is provided with and multiple casing is divided into independent filter chamber in casing 14 Dividing plate 6, filter chamber is provided above a total air-purifying chamber 9, and the outlet of air-purifying chamber 9 is arranged on casing 14, each filter chamber A corresponding ash bucket 2, each independent filter chamber is arranged over the lifting valve 11 of break-make air-purifying chamber 9 and filter chamber, gas approach 7 Being arranged on casing, gas approach 7 connects the ash bucket 2 below each independent filter chamber, in bronchial 4 by bronchial 4 It is provided with flue gas stop valve 3.Filter chamber is additionally provided with a relief valve 10.
Filtration system is made up of porous plate (card), filter bag, cage bone, is cased with a filter bag, the pulse of this type outside each cage bone Sack cleaner filter bag uses matrix arrangements mode in upright arrangement in length and breadth, and this arrangement mode reasonably make use of square casing empty Between.The card of cleaner unit, as dust catcher gas purifying chamber and the separation of filter chamber, is used for hanging filter bay assembly, simultaneously will be as dedusting The inspection platform of device filter bay assembly, relief valve 10 can be arranged on card.
It is provided with tilted-putted baffle plate 12 with gas approach 7 correspondence position, baffle plate 12 and flue gas advance side in casing 14 To in the angle of 40-50 °.When dusty gas is after air inlet enters dust-precipitator, initially strike the inclined clapboard in the middle of air inlet, gas Stream just turns to inflow ash bucket, and air velocity is slack-off simultaneously, due to gravitational settling effect, makes crude particle dust in gas fall directly into Ash bucket, plays the pre-effect gathered dust
Sometimes flue gas can be containing two a small amount of English, and traditional sack cleaner is to arrange activated carbon at gas approach Grain or activated carbon sealing coat adsorb, and are provided with active carbon powder pay-off 13 in this utility model at gas approach 7, Described active carbon powder pay-off 13 discharging opening connection gas approach 7, a small amount of activity he can carry out with flue gas by powder Filter district, can adsorb on filter bag surface subsequently, and active carbon powder now and flue gas are in the contact area of maximum, can active adsorption Two English, when accumulating a certain amount of, after activity reduces, the activated carbon on cloth bag surface can be removed by soot cleaning system, and postorder will absorption New activated carbon.
Coverboard dividing plate is divided into some independent dust chambers, carries out each dust chamber in turn according to given time interval Deashing, each dust chamber, equipped with a lifting valve, promotes valve and closes, cut through the filtered airflow of this dust chamber during deashing, with I.e. pulse valve is opened, and sprays into anhydrous oil-free high pressure cleaning air, to remove the dust on filter bag outer surface in filter bag.Respectively gather dust The pulse jet width of room and cleaning cycle, carried out by special deashing extent control device Automatic continuous.
First closing before each bin deashing and promote valve, deashing opens lifting valve after completing, due to after closing lifting valve Air-purifying chamber is in high negative pressure state so that promotes valve and opens the pulling force that needs are bigger, therefore at the gas approach of each bin After being provided with flue gas stop valve, before deashing, first close flue gas stop valve, make whole filtration bin and air-purifying chamber be in same negative pressure Under state, so that the on an off promoting valve need not bigger thrust and pulling force, protect cylinder, simultaneously convenient can carry out from Line overhauls, it is also possible to improve cleaning efficiency etc..In like manner, relief valve can also play phase same-action, and relief valve can make after opening Air-purifying chamber keeps identical with the air pressure of filter chamber.
