Abstract
The utility model relates to an air filtering device for a gas turbine engine, in particular to an air filter with a dust removing device. The air filter comprises a housing, a pulse back flushing air pipe and a cylindrical filter element arranged in the housing; one end of the cylindrical filter element is communicated with an air intake cavity of a compressor, and the other end of the cylindrical filter element is communicated with the pulse back flushing air pipe; a dust collection funnel is arranged below the cylindrical filter element; the opening of the dust collection funnel corresponds to the mounting position of the cylindrical filter element; the outlet of the dust collection funnel is formed outside the housing. Through the adoption of the technical scheme of the air filtering device, dust generated by pulse back flushing in the air filter can be discharged out of the housing in time, so that the problem of secondary pollution caused by the reason that the dust can not be discharged is avoided.
Description
Technical field
The utility model relates to a kind of gas turbine air filter, is specifically related to a kind of air filter dust-removing device.
Background technique
For fear of gas turbine inside, be subject to the impact of dust, need to install air filter additional at its air inlet, be provided with tubular element in air filter, filter core is arranged on the wall of compressor air-inlet cavity the suction port as air-inlet cavity.The air consumption of gas turbine is larger, thereby filter core will soon stop up, affect intake efficiency, so be also connected with pulse backblowing tracheae on filter core, by regularly, differential pressure or the mode such as manual control blowback frequency, to remove in time the dust of filter core outer surface, keep the filtering effect of filter core.
Due to the device of special collection dust not being set in air filter, the dust that blowback is got off cannot be discharged air filter, and along with the pumping action of gas compressor, these dusts can be re-attached on filter core, form secondary pollution, thereby affect the effect of pulse backblowing.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of air filter that can discharge in time the dust that pulse backblowing drops.
In order to solve the problems of the technologies described above, the utility model provides a kind of air filter with dust-removing device, include housing, pulse backblowing air duct and be arranged on the tubular element in housing, one end of tubular element is connected with compressor air-inlet cavity, the other end is connected with pulse backblowing air duct, described tubular element below is provided with the grey funnel of collection, collects the opening of grey funnel and the mounting point of tubular element is corresponding, and the outlet that collects grey funnel is arranged on outside housing.
Adopt the air filter with dust-removing device of technique scheme to have advantages of as follows: because tubular element below is provided with the grey funnel of collection, collect the opening of grey funnel and the mounting point of tubular element is corresponding, the outlet that collects grey funnel is arranged on outside housing, like this after pulse backblowing, the dust dropping from tubular element all can fall under gravity into the grey funnel of collection, and then from collecting the outlet of grey funnel, be discharged to the outside of air filter, avoided cannot discharging because of dust the problem that air filter brings.
As preferred version, for the ease of removing the dust in tubular element, reduce to deposit adhesion, described tubular element vertically arranges.
As preferred version, for fear of possible again the flying upward of dust of the grey hopper outlet of collection, the outlet of the grey funnel of described collection is provided with the grey pond of collection, and dust falls into the water and becomes mud, then enters subsequent technique and processes.
Accompanying drawing explanation
Fig. 1 is that the utility model embodiment is with the structural representation of the air filter of dust-removing device.
embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
The utility model provides a kind of air filter with dust-removing device as shown in Figure 1, include housing 1, pulse backblowing air duct 2 and be arranged on the tubular element 3 in housing, tubular element 3 vertically arranges, one end of tubular element 3 is connected with compressor air-inlet cavity, the other end is connected with pulse backblowing air duct 2, described tubular element 3 belows are provided with the grey funnel 4 of collection, collect the opening of grey funnel 4 and the mounting point of tubular element 3 is corresponding up and down, opening area is slightly larger than the area of shape filter core 3 mounting points, the outlet that collects grey funnel 4 is arranged on outside housing 1, the outlet that collects grey funnel 4 is provided with the grey pond 5 of collection, collect grey pond 5 intake pipe and desilting tube are set.
Above-described is only preferred implementation of the present utility model; should be understood that for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (3)
