Pulse bag filter

Abstract

The invention discloses a pulse bag filter, mainly solving the technical problems that the existing pulse bag filter has poor dust-removing effect and short service life and easily occur equipment accident when be used under high-temperature working condition and the like. The technical scheme thereof has the following key points: the pulse bag filter consists of a gas-purifying chamber (1), a filter bag (5), a filter bag skeleton (4), a filter bag (6), a blowing device (8), an ash hopper (9), a bracket (10), an inserting board valve (11) and a star-shaped rotating valve (12), wherein the dustremover is internally provided with a Venturi tube; a nozzle tube of the blowing device (8) is coupled with an ultrasonic nozzle in a movable coupling manner; the central line of the ultrasonic nozzle aligns to the central line of a bag hole; and a ladder-type Venturi tube is adopted. By adopting an ultrasonic draining nozzle, the ladder-type Venturi tube and the adjustable sealed rotating valve,the invention greatly improves ash-cleaning effect, prolongs the service life of the filter bags, expands the use range of the pulse bag filter, improves the use reliability, reduces use cost and canbe used under high-temperature working condition.

Description

technical field [0001] The invention relates to a pulse dust collector. Background technique [0002] With the development of modern industry, the pollution of dust to the environment is becoming more and more serious. It has become the consensus of the Chinese people to control the pollution of dust and purify the living environment of human beings. In order to maintain the cleanliness of the production environment, places polluted by dust must be cleaned at any time. At present, most of the cleaning work is done by installing a pulse-jet bag filter. However, during the dust removal process, the pulse-jet bag filter The filter bag of the blown bag filter will slowly bond the upper layer of dust, which will reduce the dust removal efficiency after a long period of time. Therefore, the surface of the filter bag is often cleaned according to different usage conditions in order to restore a good dust removal effect. , the injection system of the pulse-jet bag filter commonly u...

Problems solved by technology

In order to maintain the cleanliness of the production environment, places polluted by dust must be cleaned at any time. At present, most of the cleaning work is done by installing a pulse-jet bag filter. However, during the dust removal process, the pulse-jet bag filter The filter bag of the blown bag filter will slowly stick to the upper layer of dust, which will reduce the dust removal efficiency after a long period of time. Therefore, the surface of the filter bag is often cleaned according to different usage conditions in order to restore a good dust removal effect. , the injection system of the pulse-jet bag filter usually used is to blow the compressed air directly to the inner surface of the filter bag through the nozzle on the injection pipe to clean the outer surface of the filter bag, so that the cleaning effect is poor. , and it is easy to cause the filter bag to be blown out, and it will also have a certain impact on the overall work of the pulse-jet bag filter in the future, and cause dust pollution to the surrounding production environment not to be timely or perfect processing
