Abstract
A low-resistance bag type duster comprises a filtering chamber and an air purifying chamber communicated with the filtering chamber, wherein an air distributor and a rectifying passage are disposed inside an air inlet port, a rectifying partitioning plate is disposed inside the filtering chamber, the air purifying chamber is isolated from the filtering chamber via a tube sheet opened with a plurality of pores, a bag cage and a filtering bag positioned inside the filtering chamber are fixed on the tube sheet, an inner blowing tube with a diversion spray nozzle is disposed at the upper end of the tube plate inn the air purifying chamber, blowing holes are opened at the side wall of the air purifying chamber, the inner blowing tube is communicated with an outer blowing tube via the blowing holes, and the outer blowing tube is connected with an air bag. By the utility model, the dusty air is passed through the air distributor and the rectifying passage from the air inlet port, horizontally introduced into the filtering chamber, and filtered by the filtering bag, and the purified flue gas is introduced into the air purifying chamber from the filtering bag and horizontally ducted out of the duster from the air outlet port. The horizontal air inlet/outlet manner has the advantages of short flow path, and smooth and gentle flowing; and is helpful for reducing the structural resistance and running resistance of the bag type duster and reducing energy consumption of air flowing.
Description
Technical field
The utility model relates to a kind of sack cleaner, is specifically related to a kind of lower resistance sack cleaner that big air quantity ash-laden gas purifies that is used for.
Background technology
Along with the further raising of national environmental standard with to SO
2The increasing once more of control dynamics, and expense and requirement that pollutant emission is imposed are more and more higher, cause many efficiency of dust collections in the electrostatic precipitator of using as a servant not reach environmental requirement.Some electrostatic precipitator manufactories have dropped into sizable energy, have taked a lot of measures, join, change power supply etc. as increase electric field, the change utmost point, try hard to electrostatic precipitator equipment is carried out omnibearing transformation, but it are little to take effect; And in flue gas, add NH
3Improve the mode of dust removing effects, can produce very sticking deposit again, cause the vibration dust-cleaning mis-behave; Wash and can cause the corrosion of ESP shell and pole plate with water.In the case, transform electric cleaner as sack cleaner successively.
The influence that the filtration mechanism of sack cleaner has determined it changed by the exhaust gas dust physical property is very little, has efficient and reliable and stable separating power, can satisfy the environmental protection standard requirement of increasingly stringent; Sack cleaner belongs to dry-type dedusting equipment, does not exist wet scrubber mud to silt up and troublesome problem such as water treatment; Along with high temperature resistant, corrosion-resistant, the static that disappears, the exploitation refusing profit, resistance to oxidation, remove specific function filtrates such as gas, and the raising of the design of sack cleaner integral body and accessory, manufacture level, the advantage of sack cleaner appears gradually, and application just constantly enlarges.
Yet, the intake method of sack cleaner and air current composition are still permanent problem, running resistance and life-span of the filter bag that it directly has influence on sack cleaner are that equipment is realized one of long-life key of lower resistance, also whether influence the key factor of the operation of unit.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provide that a kind of resistance is little, volume is little, simple in structure, the operation maintenance is convenient, off-line ash-clearing can be applicable to the lower resistance sack cleaner that big air quantity ash-laden gas purifies.
For achieving the above object, the technical solution adopted in the utility model is: comprise the filter chamber that is provided with air inlet and ash bucket and the air-purifying chamber that is connected with the filter chamber, on air-purifying chamber, offer the gas outlet, be provided with gas distributor and rectification passage in the air inlet, be provided with Partition for realigning water flow in the filter chamber, air-purifying chamber and filter chamber isolate by the card that offers some apertures, the bag cage and the filter bag that are positioned at the filter chamber are fixed on the card, the upper end that is positioned at card in air-purifying chamber is provided with the winding-up pipe that has drainage nozzles, offer injection hole on the sidewall of air-purifying chamber, interior winding-up pipe is connected with outer winding-up pipe by injection hole, and the outer pipe of jetting also links to each other with gas bag.
Also be provided with pulse dust cleaning valve and protective cover on the gas bag of the present utility model; Offer the purging mouth on the sidewall of ash bucket and break the arch mouth, break the arch mouth and be connected with Arch-Breaking Device by the broken ball valve that encircles; Be installed with the location channel-section steel on the air-purifying chamber inwall, interior winding-up pipe is fixedlyed connected with the location channel-section steel by locating piece; Also offer manhole in the filter chamber.
Because the whole filter chamber of the utility model adopts single cell structure, the filter bag grouping is arranged in the filter chamber, dusty gas from air inlet through gas distributor, rectification passage level enters the filter chamber, filter by filter bag, clean coal gas rises up into air-purifying chamber in filter bag, and level flows out deduster from the gas outlet.The gas flow pattern of this level turnover shows short, smooth and easy, the mild characteristics that flow of flow process, is of value to and reduces sack cleaner structural drag and running resistance, reduces the gas flow energy consumption.By gas distributor being set and the rectification passage is reintegrated distribution to air-flow, gas flow rate is slowed down in the multi-faceted filter bag space that enters, and effectively avoids air-flow directly to wash away filter bag, causes regional area filter bag load excessive and erosive wear is serious.
