Abstract

The utility model discloses a low pressure pulse cloth bag deduster for solving the problem that the existing pulse cloth bag dedusters are poor in dedusting effect and short in service life, and the cloth bag is easily damaged. The low pressure pulse cloth bag deduster comprises an upper box body, a middle box body and a lower box body, wherein the middle box body is internally provided with a filter bag which is coupled with a smoke inlet arranged tangentially along the middle box body. The smoke inlet is provided with a cold air mixer selector valve communicated with a cold air pipeline. The low pressure pulse cloth bag deduster provided by the utility model has the characteristics of good dedusting effect, long service and small occupied area, and the cloth bag is difficultly damaged.

Description

Low pressure pulse bag filter
Technical field
The utility model belongs to the bag-type dust collector field, specifically, relates to a kind of low pressure pulse bag filter.
Background technology
Along with the develop rapidly of modern industry, industrial and mining enterprises all can produce a large amount of dust, and dust is on the rise to the pollution of environment, particularly processing industries such as metallurgy, mine, chemical industry, cement, generating, grain.Administer the pollution of dust, purify living environment, become people's common recognition.At present, mostly be to carry out cleaning by pulse bag formula deduster is installed.
For example Granted publication number discloses a kind of high-voltage pulse sack cleaner for the patent document of CN 201669014 U, comprise upper box, middle casing, blast pipe, ash bucket, blowing device and vertical-lift valve, the top of casing during upper box is located at, be plugged with injection system and vertical-lift valve in the upper box, ash bucket is fixedlyed connected with middle casing, be provided with pillar around the middle casing, blast pipe is connected with middle casing.
For example Granted publication comprises upper box, middle casing, lower box and computer pulse controller number for the patent document of CN 202052427 U discloses a kind of low pressure pulse bag filter again, and upper box comprises loam cake, card and deashing device; Be provided with filter bag in the middle casing, filter bag is fixed on the filter bag fixed mount; The built-in hawk of scraping of lower box, the lower box below arranges scraper plate reducing motor and airlock motor.
Yet existing pulsed jet cloth filter dust removing effects is poor, and cloth bag damages easily, the problem that service life is short.
The utility model content
The utility model is to overcome the problem that existing pulsed jet cloth filter exists, and a kind of low pressure pulse bag filter is provided, and have good dedusting effect, and cloth bag is not easy to damage the characteristics of long service life.
For addressing the above problem, the technical solution adopted in the utility model is:
Low pressure pulse bag filter, comprise upper box, middle casing and lower box, be provided with filter bag in the described middle casing, described filter bag connects with the tangential smoke air inlet that arranges of casing in the edge, it is characterized in that: described smoke air inlet is provided with mixer selector valve, described mixer selector valve and cold air duct UNICOM.
Further, described filter bag top is provided with elastic piston ring, and described elastic piston ring is embedded on the card of middle casing.
Further, described filter bag adopts laminated needled felt to make.
Further, described filter bag length is greater than 6m.
Compared with prior art, the utlity model has following beneficial effect:
One, the utility model comprises upper box, middle casing and lower box; Be provided with filter bag in the middle casing, filter bag connects with the tangential smoke air inlet that arranges of casing in the edge, and smoke air inlet is provided with mixer selector valve, mixer selector valve and cold air duct UNICOM.When the temperature sensor in the deduster detects flue-gas temperature above setting value, open mixer selector valve automatically, sneak into cold air, reduce flue-gas temperature, the protection filter bag, thus improve dust removing effects, the service life of prolongation filter bag.
Two, filter bag of the present utility model top is provided with elastic piston ring, during elastic piston ring is embedded on the card of casing, and dismounting and that filter bag is installed is very convenient, operating personnel change bag in the pure qi (oxygen) case, can not contact with the dirt bag, have improved operating personnel's operating environment.
Three, filter bag of the present utility model adopts laminated needled felt to make, and than the filter bag that other materials are made, dust removing effects is better, improves dust removal performance of the present utility model.
Four, filter bag length of the present utility model is greater than 6m, big quantum jump the long limit of bag of the pulse dust collector that it has been generally acknowledged that, when improving dust removing effects, reduced floor space of the present utility model, improve practicality of the present utility model.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model filter bag;
Mark among the figure: 1, upper box, 2, the flue gas air inlet, 3, mixer selector valve, 4, cold air duct, 5, middle casing, 6, filter bag, 7, lower box, 8, elastic piston ring.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and the specific embodiments.
Low pressure pulse bag filter of the present utility model comprises upper box, middle casing and lower box, is provided with filter bag in the middle casing, and filter bag connects with the tangential smoke air inlet that arranges of casing in the edge, and smoke air inlet is provided with mixer selector valve, mixer selector valve and cold air duct UNICOM.Mixer selector valve of the present utility model belongs to prior art products, mixer selector valve and cold air duct UNICOM.Cold air duct can with cold wind storage container UNICOM, cold air duct also can with air blast UNICOM, perhaps the equipment that other can output cold wind connects.
When the temperature sensor of deduster detects flue-gas temperature above setting value, open mixer selector valve automatically, sneak into cold air, reduce flue-gas temperature, the protection filter bag, thus improve dust removing effects, the service life of prolongation filter bag.
Further, the filter bag top is provided with elastic piston ring, and elastic piston ring is embedded on the card of middle casing, by the mode of this embedding, dismounting and installation filter bag are very convenient, and operating personnel change bag in the pure qi (oxygen) case, can not contact with the dirt bag, improved operating personnel's operating environment.
Filter bag of the present utility model adopts laminated needled felt to make, and than the filter bag that other materials are made, dust removing effects is better, improves dust removal performance of the present utility model.
Further, filter bag length is greater than 6m, big quantum jump the long limit of bag of the pulse dust collector that it has been generally acknowledged that, when improving dust removing effects, reduced floor space of the present utility model, improve practicality of the present utility model.Filter wind scooter 2.7m/min of the present utility model, and Daxing chamber-dividing counter-blowing sack cleaner is generally all below 1.0m/min, the design is according to the dust characteristics, and filtration velocity is got 1.2m/min.Long bag filter bag, the effect of dedusting greatly that data declaration, the utility model adopt.
The utility model adopts straight-through pulse valve, and resistance is low, opens and closes soon, and the deashing ability is strong.The injection system each several part all has good aerodynamic characteristics.It directly utilizes sack to play ejector action, and jetting pressure only needs 0.15~0.25MPa, and the winding-up time shortens to 0.065~0.085s, and operation energy consumption is lower than backblowing cloth-bag dust collector.
In sum, the utility model can improve dust removal performance, and can be good at protecting filter bag, improves service life.
