Overview of dmc-312 single bag filter: this single bag filter is a small bag filter designed by our company after digesting and absorbing the technology of similar products. This kind of dust remover adopts the technology of high pressure (0.5 ~ 0.7MPa) and large flow pulse valve to spray and clean the dust one by one. Compared with other single machine in China, it has the characteristics of high dust removal kinetic energy and dust removal.
Dmc-312 single bag filter has the advantages of small volume, light weight, simple and compact structure, easy installation and easy maintenance (external filter type). It is widely used in the purification and treatment system of dust containing gas in building materials, metallurgy, mining, coal, non-metallic mineral powder processing and other industries. It is an ideal equipment for environmental protection and dust removal.
1. The working principle of dmc-312 single bag filter is as follows:
The dust containing gas enters the ash hopper through the air inlet or enters the filter bag room through the open flange port. The dust containing gas is filtered through the filter bag into the clean air chamber, and then is discharged by the fan through the exhaust port of the air purification chamber. The dust accumulates on the outer surface of the re filter bag and increases continuously, which makes the resistance of the bag filter rise continuously. In order to make the resistance of the equipment not exceed 1200 PA, the bag dust collector can continue to work, and it is necessary to filter the dust on the bag regularly. The program controller starts the pulse valve in time and sequence to make the compressed air (0.5 ~ 0.7MPa) in the air bag. The compressed air (called primary air) is ejected from the hole of the blowing pipe. Through the venturi tube, the surrounding air (called secondary air) which is several times as much as the primary air is induced to enter the filter bag, which expands rapidly in an instant, and shakes off the dust with the reverse effect of the air flow to achieve the purpose of dust removal.
2. Structure of single bag filter
The equipment is mainly composed of the following parts:
(1) Box body: including bag chamber, air purification chamber, perforated plate, filter bag, filter bag framework, access door and cabinet, with design pressure of 5000Pa.
(2) Injection system: including main gas pipe, injection pipe, pulse valve and control instrument.
(3) There are two forms of the intake and exhaust part: one is the standard type with ash hopper, the other is the open flange type.
