Abstract
The utility model belongs to the technical field of the technique of the compound dust remover of thermal power factory electricity bag and specifically relates to a compound dust remover electricity bag jetting system of thermal power factory electricity bag, sweep the deashing unit including gas tank, solenoid proportional valve, injection pipe, the control unit and four single -row sacks of setting on the gas tank, every single -row sack all be provided with outwardly directed pipeline on sweeping the deashing unit, install the single control valve that the single -row sack of control swept deashing unit switch on the pipeline, the pipeline sweeps deashing unit parallel connection with four single -row sacks. The utility model discloses the solenoid proportional valve that sweeps the deashing unit at one of them the single -row sack back of breaking down stops the work that this single -row sack swept the deashing unit, neither influences the jetting deashing of other unit control systems, has guaranteed the solenoid proportional valve's on the unit gas tank change and maintenance again, has practiced thrift the normal operating that the life who has guaranteed electric bag dust remover with tolerance had guaranteed the unit simultaneously.
Description
Technical field
The utility model relates to the technical field of thermal power plant electric-bag complex dust collector, especially a kind of thermal power plant electric-bag complex dust collector electricity bag injection system.
Background technology
Be applied to the deduster in thermal power plant, by the FE type electric-bag complex dust collector of the F365-4 type electric cleaner of #3 unit-#8 unit, a Ge electricity district is become by original five Ge electricity districts, the electric-bag complex dust collector in four Ge Dai districts, electricity district purge mode adopts the purge mode of top electromagnetic shaking, bag district adopts four gas tank series connection injection method deashings of four groups of female pipe central gas supplies of single-row gas tank, along with unit puts into operation time lengthening, the defect of four gas tank series connection injection methods of four groups of female pipe central gas supplies of single-row gas tank progressively reveals, as: the electromagnetic impulse valve on a gas tank in four gas tank series connection injection methods of the female pipe central gas supply of single-row gas tank breaks down to be failure to actuate or to leak gas and just needs whole unit air feed to cut off to carry out processing or changing electromagnetic impulse valve, cause single-row pneumostatic Shi Dai district gateway pressure reduction to increase and cause electric bag paste bag to reduce the life-span of electric bag, dust collector efficiency reduces simultaneously.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of thermal power plant electric-bag complex dust collector electricity bag injection system.
The utility model solves the technical scheme that its technical problem adopts: a kind of thermal power plant electric-bag complex dust collector electricity bag injection system, comprise gas tank, electromagnetic impulse valve, playpipe, control unit and be arranged on four single-row cloth bags purging deashing unit on gas tank, described each single-row cloth bag purges on deashing unit and is provided with outwardly directed pipeline, pipeline is provided with and controls the single control valve that single-row cloth bag purges deashing unit switch, four single-row cloth bags are purged deashing unit and are connected in parallel by pipeline.
The beneficial effects of the utility model are: after the electromagnetic impulse valve that the utility model single-row cloth bag wherein purges deashing unit breaks down, this single-row cloth bag is stopped to purge the work of deashing unit, neither affect the jetting deashing of other unit control systems, in turn ensure that replacing and the maintenance of the electromagnetic impulse valve on unit gas tank, save gas the normal operation that the service life that ensure that electrostatic fabric filter ensure that unit simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is the structural representation before original cleaner reform.
Fig. 2 is structural representation of the present utility model.
In figure: 1, single-row cloth bag purges deashing unit, 2, pipeline, 3, single control valve.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Thermal power plant electric-bag complex dust collector electricity bag injection system as shown in Figure 2, comprise gas tank, electromagnetic impulse valve, playpipe, control unit and four single-row cloth bags and purge deashing unit 1, each single-row cloth bag purges on deashing unit 1 and is provided with outwardly directed pipeline 2, pipeline 2 is provided with and controls the single control valve 3 that single-row cloth bag purges deashing unit 1 switch, four that are arranged on gas tank single-row cloth bags are purged deashing unit 1 and are connected in parallel by pipeline 2.
After arbitrary single-row cloth bag electromagnetic impulse valve purged on deashing unit 1 on gas tank breaks down, only the single control valve 3 that this single-row cloth bag purges on deashing unit 1 need be closed, just can overhaul electromagnetic impulse valve or change, ensure that other single-row cloth bag purges deashing unit 1 and do not affect by it, can normally work, both ensure that the normal operation of electric-bag complex dust collector, can not impact service life cloth bag simultaneously.
As shown in Figure 1, before transformation, the single control of source of the gas mother pipe, gas phase series operation, only has a control valve, cause the electromagnetic impulse valve in arbitrary group on gas tank to break down or change and overhaul the valve closing that all will will control, cause the single-row cloth bag in whole electric-bag complex dust collector to purge soot cleaning system all out of service, not only affect the normal operation of electric-bag complex dust collector but also affect the maintenance of maintenance defect elimination, service life certain impact is produced to cloth bag simultaneously.
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
