Abstract
The invention discloses a pulse sac deduster which comprises a deduster body and further comprises air chambers symmetrically mounted on two sides of a box of the deduster and an air way communicated with inlets and outlets of the air chambers on the two sides respectively. Each air chamber is of a closed box structure, a partition arranged on the inner side of each air chamber divides the corresponding closed box structure into a turbid air chamber and a purified air chamber which are independent mutually, the portion above each partition is the corresponding purified air chamber while the portion below the same is the corresponding turbid air chamber, each turbid air chamber is communicated with a dedusting chamber inlet of the deduster, and an outlet of a dedusting chamber is communicated with each purified air chamber through an offline valve. The purified chambers and the turbid air chambers are welded on two sides of the deduster box, so that space for air incoming and outgoing between the box on two sides of the deduster is saved. When an electrostatic deduster is modified, various internal parts are removed, and with the exception that a foundation of an original deduster is not moved, a shell, an ash bucket, a dust collection pipeline and an ash conveying device of the original deduster are retained, so that project quantity is reduced, project expense is lowered, and construction time is shortened.
Description
Technical field

For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of pulsed jet cloth filter, including cleaner body, the air chamber that also includes being symmetrically mounted on the casing both sides of cleaner unit and respectively with the air channel of the chamber inlet of both sides and outlet, described air chamber is closed box structure, closed box segmentation of structures is become separate foul smell room and air-purifying chamber by the dividing plate arranged inside it, dividing plate above part is air-purifying chamber, part below dividing plate is foul smell room, described foul smell room connects with the dirt pocket entrance of cleaner unit, the outlet of dirt pocket is connected with air-purifying chamber by off-line valve.
Described air channel includes induction part and outlet gas part, induction part and outlet gas part are symmetrically mounted on the casing both sides of cleaner unit, described induction part includes being fixedly mounted on the import horn mouth outside the casing of cleaner unit and side blast pipe, the big end of import horn mouth seals with the casing lateral surface of cleaner unit and docks, import horn mouth small end is closed and is arranged, side blast pipe is overlapped in the through connection two in import horn mouth both sides, import horn mouth inner chamber connects with foul smell room, described outlet gas part includes outlet loudspeaker mouth and side air-out pipe, described outlet loudspeaker mouth hold greatly with the casing of cleaner unit outside closed and butted, and its inner chamber connects with air-purifying chamber, outlet loudspeaker mouth small end is closed and is arranged, the through installation side discharge pipe in outlet loudspeaker mouth both sides.
Through bottom described foul smell room arranging air intake square tube under four sets, the four lower air intake square tube lower ends of set connect the dirt pocket in cleaner unit, and the often corresponding a set of dirt pocket of set lower blast pipe, often the set dirt pocket port of export connects air-purifying chamber each through Off-line valve.
Described dividing plate is horizontally disposed with.
Described dividing plate is obliquely installed.
Described dividing plate and air-purifying chamber top all seal installation and repairing hole.
Adopt and have the beneficial effects that produced by technique scheme: by air-purifying chamber and foul smell room are welded on dust collector box body both sides, save the space of air inlet/outlet in the middle of cleaner unit two side box body. When Retrofit of Electrostatic Precipitator, removing internal various parts, the ground of former cleaner unit is motionless, retains the shell of former cleaner unit, ash bucket, dust collection pipeline, ash conveying device, therefore makes quantities reduce, reduces engineering cost, shortens the engineering time.
