Description
Technical field
The utility model relates to field of environment protection equipment, particularly a kind of dedusting pulse valve malfunction elimination device.
Background technology
Action of low-voltage pulse long bag dust collector of jetting is novel, the high-efficiency bag type dust remover of the one that grows up on the basis of summing up various sack cleaner.It adopts off-line action of low-voltage pulse jetting deashing technology, prevents dust attached and out of control problem again, enhances the ash-removal effect of filter bag, improve the rate of filtration, saves the life-span of deashing energy consumption and prolongation filter bag.Deduster adopts PLC programmable controller, automatically controls the overall process of deashing, defeated ash.Therefore, this deduster a kind ofly processes the large-scale cleaner that air quantity is large, ash-removal effect good, efficiency of dust collection is high, reliable, easy to maintenance, floor space is little.
Electromagnetic pulse valve diaphragm is divided into two, front and back air chamber pulse valve, when electromagnetic impulse valve connects cleaning compressed air in pulse pocket type dust catcher deashing system, compressed air is through throttle orifice, enter rear gas chamber, now diaphragm is close to the gas outlet of valve by rear gas chamber's pressure, pulse valve is in closed condition, when receiving pulse signal, pulse valve armature moves, valve rear gas chamber air vent is opened, the rapid decompression of rear gas chamber, move after making diaphragm, compressed air is jetted by the gas outlet of valve, pulse valve is in opening winding-up to start, pulse signal is lost, the electromagnetic pilot title iron of pulse valve resets, rear gas chamber's air vent is closed, rear gas chamber's pressure raises and makes pulse valve diaphragm be close to the gas outlet of valve, pulse valve is in closed condition, winding-up stops.And pulse valve fault directly causes ash-removal effect not good, long-play, causes deduster pressure reduction to increase, and increases the load of dedusting fan.Pulse valve diaphragm damages and also causes a point gas bag pressure drop, and serious causes whole point of gas bag, even multiple points of gas bag insufficient pressures, and pulse valve partly or entirely lost efficacy, and have impact on the normal operation of dedusting.
Current deduster soot cleaning system has widely used pulse backblowing soot cleaning system, and each deduster of large-scale deduster has up to a hundred pulse valves, and owing to working long hours, the large diaphragm of Electrical heads, pulse valve, Small diaphragm-piece are fragile.If diaphragm is bored a hole, then pulse valve steam vent gas leakage; If diaphragm damages but puncherless, leak to deduster body in compressed air.Leak outside visual phenomenon, but which room pulse valve gas leakage is interior leakage phenomenon only can recognize, but cannot judge it is which pulse valve fault concrete.Point of gas bag has tens even tens pulse valves, if check large diaphragm one by one, then checks loaded down with trivial details, wastes time and energy; If closedown lift valve, open access door inspection, then affect the normal operation of deduster.Two kinds of methods are all difficult within very short time, confirm which pulse valve fault, bring very large difficulty to equipment point-detecting work.
Utility model content
The purpose of this utility model is for solving the problem, and provides a kind of dedusting pulse valve malfunction elimination device.
In order to achieve the above object, the utility model provides following technical scheme: a kind of dedusting pulse valve malfunction elimination device, comprise pulse valve, point gas bag and injection tube, a described point gas bag is arranged in injection tube, one end of injection tube is stretched in the casing of deduster, and described injection tube is also provided with an arm, and described arm is arranged between dust collector box body and point gas bag, described arm is also provided with a valve, and described valve is normally off.
Improve as one of the present utility model, described valve is a manually-operated gate.
Beneficial effect:
Dedusting pulse valve malfunction elimination device of the present utility model, structure is simple, easy to operate, can investigate down pulse valve fast, also can the fault type of failure judgement pulse valve, is convenient to line service.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Wherein:
1-pulse valve, 2-divide gas bag, 3-injection tube, 4-arm, 5-valve, 6-steam vent.
Detailed description of the invention
Below with reference to specific embodiment, the technical scheme that the utility model provides is described in detail, following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
A kind of dedusting pulse valve malfunction elimination device as shown in Figure 1, comprise pulse valve 1, point gas bag 2 and injection tube 3, a described point gas bag 2 is arranged in injection tube 3, one end of injection tube 3 is stretched in the casing of deduster, described injection tube 3 is also provided with an arm 4, described arm 4 is arranged between dust collector box body and point gas bag 2, and described arm 4 is also provided with a valve 5, and described valve 5 is normally off.Valve 5 is a manually-operated gate.
The operation principle of this device is: if the large diaphragm perforation of pulse valve, then divide gas bag compressed air to be directly directly disposed to air through breakage, injection tube steam vent, cause and leak; If large diaphragm is puncherless, rubber cushion damages, then large diaphragm cannot be fitted the injection tube mouth of pipe, and also cannot play sealing effectiveness, point gas bag compressed air flows in deduster through the gap of film and the injection tube mouth of pipe, lets out in causing.
Specifically fix a breakdown time, which room fault is the method for employing: according to gas leakage sound, tentatively judge; Check whether pulse valve steam vent 6 leaks gas, if gas leakage, then diaphragm perforation; Otherwise open arm valve, arm leaks gas, then the large diaphragm of pulse valve damages, but puncherless..
Dedusting pulse valve malfunction elimination device of the present utility model, structure is simple, easy to operate, can investigate down pulse valve fast, also can the fault type of failure judgement pulse valve, is convenient to line service.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment; also comprise the technical scheme be made up of above technical characteristic; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
