Description
Technical field
The utility model relates to sack cleaner field, particularly the single valve plate zero leakage bypass valve on a kind of sack cleaner bypass flue.
Background technique
In environmental protection industry (epi), sack cleaner is the capital equipment of the flue gas of generation while processing all kinds of boilers, incinerator burning.Deduster body structure is roughly divided into ash bucket, air intake pipe, raising middle flask, top box, air outlet tube, bypass airduct, injection tube, filtrating equipment etc., its concrete principle is: flue gas is under blower negative pressure, through air intake supervisor and air intake short tube, enter in ash bucket, meal dirt is fallen in ash bucket, fine dust rises in raising middle flask with air-flow, overworks filter cloth in raising middle flask, and air-flow enters upper box through filter cloth, until air outlet tube, dust removal process finishes.
In the flue gas that boiler, incinerator produce while burning, not only contain more dust, sometimes also can contain a large amount of vaporish acidic liquids, surpass the temperature that cloth bag can bear, as directly entered sack cleaner, can cause on the one hand burning bag, stick with paste bag phenomenon, also can cause corrosion or make dust solidify, lump cloth bag on the other hand.Therefore, generally can before flue gas enters deduster, set up bypath system, flue gas can directly enter rear equipment by the by-pass collar between air intake pipe and air outlet tube, carries out the processing of high-temperature acidic flue gas.Will run into like this problem, when flue-gas temperature is not high, when sack cleaner is normally worked, must guarantee the bypass valve zero leakage of by-pass collar, not so can make the smoke spillage that contains acidic liquid, cause secondary air pollution.In order to make bypass valve sealing, guarantee zero leakage, generally adopt two-layer valve plate, or the method for single valve plate increase sealing gasket, but double valve plates can increase maintenance and manufacture cost, and sealing gasket is as for a long time under high temperature and acidic flue gas effect, be easy to be corroded, cause sealing gasket damaged, smoke spillage.Single valve plate zero leakage bypass valve of the present utility model can overcome the above problems well.
Summary of the invention
The utility model provides the bypass valve of the single valve plate zero leakage on a kind of sack cleaner bypass flue, can make bypass valve zero leakage and solid durable, non-maintaining.
The utility model is achieved by the following technical programs:
A sack cleaner single valve plate zero leakage bypass valve, it is arranged in the sack cleaner that internal environment is negative pressure, comprising:
Valve body, it has hollow ventilating chamber;
Valve seat, it is positioned at the suction port place of the hollow ventilating chamber of described valve body, and the middle part of described valve seat has the through hole that connects hollow ventilating chamber and external feed stream pipeline, and outer periphery have connect with atmosphere and with the air vent of described hollow ventilating chamber perforation;
Valve plate, it is positioned at described hollow ventilating chamber, and shutoff is on described through hole and described air vent.
Described bypass valve also comprises:
Valve rod, it is through described valve body hollow ventilating chamber, and upper end connects upper and lower driving mechanism, lower end is connected with described valve plate central vertical, by the upper and lower push-and-pull valve rod of driving mechanism, valve plate is moved up and down in described valve body hollow ventilating chamber, and then control the open and close of described valve seat through-hole;
Atmospheric communicating pipe, it is communicated with atmosphere and air vent, and making air vent internal air pressure is barometric pressure.
Preferably, described upper and lower driving mechanism is motor or cylinder.
Described atmospheric communicating pipe is arranged on described air vent sidepiece.
Described valve seat is telescoping structure.
Described valve plate is made by deformable metal material, in the time of can making like this valve plate shutoff on described valve seat through-hole and described air vent, micro-distortion occurs, and in air vent opening both sides, forms natural gap, makes atmosphere enter bypass valve by this natural gap.
The beneficial effects of the utility model are:
The ingenious duster system inside that utilizes of the utility model single valve plate bypass valve is for suction function; in valve seat outer periphery, the logical air vent of atmosphere is set; this bypass valve is not only simple in structure; manufacture easy for installation; and can guarantee that sack cleaner normally moves time, bypass valve zero leakage, can reduce user's nonrecurring cost and drop into and reduce equipment operation maintenance cost; when protecting cloth bag, can guarantee air again pollution-free.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, to make those skilled in the art can implement according to this with reference to specification word.
A sack cleaner single valve plate zero leakage bypass valve, it is arranged in the sack cleaner that internal environment is negative pressure, comprising:
Valve body (3), it has hollow ventilating chamber; Valve seat (4), it is positioned at the suction port place of the hollow ventilating chamber of described valve body, and the middle part of described valve seat (4) has the through hole that connects hollow ventilating chamber and external feed stream pipeline, and outer periphery have connect with atmosphere and with the air vent (5) of described hollow ventilating chamber perforation; Valve plate (2), it is positioned at described hollow ventilating chamber, and shutoff is on described through hole and described air vent (5).
Described bypass valve also comprises:
Valve rod (1), it is through described valve body (3) hollow ventilating chamber, upper end connects upper and lower driving mechanism, lower end is connected with described valve plate (2) central vertical, by the upper and lower push-and-pull valve rod of driving mechanism (1), valve plate (2) is moved up and down in described valve body (3) hollow ventilating chamber, and then control the open and close of described valve seat (4) through hole; Atmospheric communicating pipe (6), it is arranged on described air vent (5) sidepiece, is communicated with atmosphere and air vent (5).In the present embodiment, atmospheric communicating pipe (6) is made by stainless steel material, and upper and lower driving mechanism is selected motor.
