Description
Technical field
The utility model relates to the flue gas purifying equipment field, is specifically related to a kind of double-layer combined filter cylinder.
Background technology
Filter cylinder belongs to the surface filtration element, and it is that the small ventilative tissue that utilizes surface of filter medium to form stops to fall the particulate matter in air or the liquid.The filtrate of common filter cylinder has wood pulp cellulose filter paper, spun-bond process polyester fiber nonwoven, and woven wire, wherein polyester non-woven fabric can carry out overlay film, grease-proof and waterproof, antistatic is handled.
Granted publication number is used compound filter cylinder for the utility model of CN201240954Y discloses a kind of purifying waste water, comprise the filtration urceolus, water supply connector, in filtering urceolus, inner canister is arranged, inner canister is connected the tube end water supply connector inboard of filtering urceolus by the O RunddichtringO, in inner canister, be filled with the hollow permeable fiber, be positioned at the front portion of inner canister after the hollow port side seal of hollow permeable fiber, rear wall in inner canister has the annular pass-through groove, the annular pass-through groove connects the space of filtering between urceolus and the inner canister, be filled with nonwoven in the space with respect to annular pass-through groove place, be filled with active carbon at the filtration urceolus at middle part and the gap between the inner canister, be filled with the fiber-reactive charcoal at the filtration urceolus in the outside and the gap between the inner canister, at the wall with respect to the fibre active carbon outside that filters urceolus delivery port arranged.
The automatic ash removing mode that filter cylinder is commonly used has gases at high pressure pulse backblowing and mechanical oscillation.The gases at high pressure pulse backblowing is to utilize the controller preset parameters to give signal of magnetic valve, and moment opens and closes the magnetic valve diaphragm, makes gases at high pressure enter the winding-up pipe, utilizes the rapid expansion power of gas to shake off the dust on filter cylinder surface.The mechanical oscillation deashing is usually used in the miniature single-machine filter cartridge dust remover, utilizes the float force that eccentric produces on the bag filter tubesheet to come deashing.
In the prior art, the filter area of the filter cylinder of same size depends primarily on the fold number of fibrous paper, and fold number filter area more at most is more big, but, be subjected to the restriction of processing technology, the fold number can reach bottleneck after reaching some, can not satisfy the demand that continues to increase filter area.
The utility model content
The utility model provides a kind of double-layer combined filter cylinder, can increase on the one hand the filter area of filter cylinder, and on the other hand, the gas pressure drop in the time of can improving the pulse backblowing deashing is conducive to the carrying out of deashing.
A kind of double-layer combined filter cylinder, comprise columnar body, the periphery of this body is air inlet face, body shaft to an end be the gas outlet, described body shaft to the other end be air inlet, the inside of described body is provided with the inner filtration tube of taper, and the big opening end of this inner filtration tube is connected with the edge of described air inlet.
Part flue dust enters in the body via the air inlet face of body, another part flue dust at first via body shaft to air inlet enter the inside of inner filtration tube, enter in the gap between inner filtration tube and the body via the conical surface of inner filtration tube then, two parts flue dust is through after filtering, by body shaft to the gas outlet discharge.
The inner filtration tube is set to taper, during deashing, gas is to purge laying dust on the conical surface with the conical surface of taper direction in a certain angle, and is cylindrical if the inner filtration tube is made as, then the purging direction of gas parallels with the sidewall of columniform inner filtration tube, the laying dust on the sidewall that is difficult for blowing off.
As preferably, described inner filtration tube is 1:1～2 with the ratio of the axial length of body.
Gas pressure drop and circulation of air when the inner filtration tube is used for this kind pulse dust cleaning, therefore, the size of inner filtration tube does not need very big, and further preferred, described inner filtration tube is 1:1.1～1.5 with the ratio of the axial length of body.
The drift angle of inner filtration tube is more big, then during pulse dust cleaning, the angle of the conical surface of gas and taper is more big, more be conducive to the carrying out of deashing process, and the drift angle of taper is more little, then the area of the conical surface of inner filtration tube is more big, be conducive to increase filter area, therefore, take into account this two factors, preferably, the drift angle of described inner filtration tube is 15～45 degree.Further preferred, the drift angle of described inner filtration tube is 15～30 degree.
As preferably, the osculum end of described inner filtration tube has sealing cap.Sealing cap prevents that flue dust from directly being entered in the body by the osculum end of inner filtration tube, makes the clean-up effect variation.
The utility model also provides a kind of flue gas purifying equipment, comprises the housing that has air inlet and air outlet, is furnished with described double-layer combined filter cylinder in the described housing, is provided with air-introduced machine between the gas outlet of double-layer combined filter cylinder and the air outlet of housing.Flue gas under effect, enters enclosure interior at air-introduced machine, and through after the filtration of double-layer combined filter cylinder, purifying air of obtaining discharged by air outlet.
The double-layer combined filter cylinder of the utility model, when increasing the filter cylinder filter area, the gas pressure drop when improving the pulse backblowing deashing is conducive to the carrying out of deashing.
