Description
Technical field
The utility model relates to a kind of combustion gas pulsed ash disposal filter.
Background technology
Along with the growth requirement that urban modernization is built, the use of natural gas is also more and more extensive, and transfering natural gas from the west to the east, contains abundant natural gas by very long Cemented filling to eastern region western part.Gas transmission and distribution system is similar to electrical power distribution system, i.e. gas supply station boosting-conveying-step-down-user.
Due in very long course of conveying, in conveyance conduit, there is iron rust, the grains of sand, foreign material etc. impurity.Relatively more serious to gas-fired equipment damage, this just needs these contaminant filters to fall.
In gas transmission and distribution process, after the filter core of filter uses a period of time, filter core will adhere to a lot of dust, impurity and filter core blocking is affected the flow of combustion gas in pipeline.After using a period of time, remove dust on filter core 2 will: (1) closes intake valve (stopping the supple of gas or steam) on gas pipeline, (2) displace natural gas in pipe network with nitrogen, the blind plate on filter staving is opened by (3), spins off screw and takes out after filter core cleaning dust above, impurity from newly installing.
Utility model content
Goal of the invention of the present utility model is to provide a kind of combustion gas pulsed ash disposal filter.
It is as follows that the utility model solves the problems of the technologies described above taked technical scheme:
A kind of combustion gas pulsed ash disposal filter, comprising: pulse valve (6), a termination nitrogen cylinder (7), another termination injection tube (4), and pulse valve (6) controls the opening and closing of pulse valve (6) by pulse control instrument (8); The end of injection tube (4) connects Venturi tube (3), and injection tube (4) and Venturi tube (3) are located at again in filter core (3), filter core (3) is connected with filter staving (9) by screw (1), and filter core (3) is located in this filter staving, the lower end of described filter staving (9) connects a blowoff valve (5), upper end connects blind plate (11) by stud (10), and this blind plate (11) is arranged at filter staving upper end, and fits tightly with filter staving upper end.
Further, preferably, the staving two ends of described filter staving (9) are connected with two pipelines, are respectively inlet pipe and go out pipe.
After this invention takes such scheme, control the opening and closing of pulse valve (6) by pulse control instrument (8) by pulse valve (6), injection tube (4) can be impelled to carry out deashing, there is extraordinary technique effect.
Other features and advantages of the utility model will be set forth in the following description, and, partly become apparent from description, or understand by implementing the utility model.The purpose of this utility model and other advantages realize by structure specifically noted in write description, claims and accompanying drawing and obtain.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail, to make above-mentioned advantage of the present utility model definitely.
Fig. 1 is the structural representation of the utility model combustion gas pulsed ash disposal filter.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in detail.
Specifically, the present invention is directed to above defect, overcome the deficiencies in the prior art, provide a kind of and save time, the pulsed ash disposal filter of laborsaving, joint medicine cost.Realizing such scheme is: as shown in the figure: 1 screw; 2 filter cores; 3 Venturi tubes; 4 injection tubes; 5 blowoff valves; 6 pulse valves; 7 nitrogen cylinders; 8 pulse control instruments; 9 filter stavings; 10 studs; 11 blind plates.
Wherein, specifically, a kind of combustion gas pulsed ash disposal filter, comprising: pulse valve 6, a termination nitrogen cylinder 7, another termination injection tube 4, and pulse valve 6 controls the opening and closing of pulse valve 6 by pulse control instrument 8; The end of injection tube 4 connects Venturi tube 3, and injection tube 4 and Venturi tube 3 are located at again in filter core 3, filter core 3 is connected with filter staving 9 by screw 1, and filter core 3 is located in this filter staving, the lower end of described filter staving 9 connects a blowoff valve 5, upper end connects blind plate 11 by stud 10, and this blind plate 11 is arranged at filter staving upper end, and fits tightly with filter staving upper end.
Further, preferably, the staving two ends of described filter staving 9 are connected with two pipelines, are respectively inlet pipe and go out pipe.
After this invention takes such scheme, control the opening and closing of pulse valve 6 by pulse control instrument 8 by pulse valve 6, injection tube 4 can be impelled to carry out deashing, there is extraordinary technique effect.
Operation principle: pulse valve 6 one termination nitrogen cylinder 7 and another termination injection tube 4.Pulse control instrument 8 controls the unlatching of pulse valve 6, and when pulse control instrument no signal exports, the exhaust outlet of pulse valve 6 is closed.When pulse control instrument 8 sends signal, exhaust outlet is opened, nitrogen now in nitrogen cylinder 7 is sprayed through injection tube 4 by pulse valve 6, namely the gas sprayed from injection tube 4 is First air, when high velocity air by Venturi tube 3 induction of the ambient gas being several times as much as First air, be commonly referred to as Secondary Air, enter filter core 2 and cause instantaneous malleation in filter core 2, realize deashing.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
