One, DMC type pulse single bag filter:
DMC type single pulse bag filter is a small bag precipitator, our company digestion and absorption of foreign advanced technology, the improved designed, the dust catcher is using high pressure large flow valve (0.5~0.7MPa) pulse bag by blowing ash cleaning technology, compared with other domestic stand-alone DMC type single bag dust collector the cleaning pulse has great kinetic energy characteristics of high cleaning efficiency. Light weight and small volume, simple and compact structure, easy installation and convenient maintenance (external type), DMC type single pulse bag filter is widely used in dust gas processing system of building materials, metallurgy, mining, coal, non-metallic mineral powder processing and other industries, is the ideal equipment for environmental protection.
Two. The structure and working principle of DMC type pulse single machine bag filter:
1, single bag filter structure
The equipment is mainly composed of the following parts:
(1): the box comprises a bag chamber, net chamber, porous plate, filter bag, filter bag frame, access door, cabinet design pressure 5000Pa.
(2) injection system including main pipe, nozzle, valve, pulse control instrument.
(3) an ash discharging part has two forms: one is the standard with bucket type, the other is the open flange.
2, DMC type pulse single bag filter working principle:
Dust containing gas from the inlet into the hopper or through the open flange into the filter bag chamber, dust containing gas through the filter bag filter net gas enters a clean air chamber, the air purifying chamber outlet and discharged by blower fans. The outer surface of the bag dust deposition, and increasing the bag dust resistance rising, the resistance of the equipment does not exceed 1200Pa, bag dust remover can continue to work regularly to remove dust on bag. Cleaning is a program controller timing sequence starting pulse valve, the compressed air bag (0.5~0.7MPa), by blowing out holes (called a wind) induced by several times in a wind around the air through the venturi (called two wind) into the bag expands rapidly in an instant, and accompanied by anti air the orientation of shake off the dust, to achieve the purpose of dust cleaning.
Three, DMC type pulse single bag filter
1, model description
The machine has 32, 48, 64, 80, 96, six 112 kinds of specifications, each of which is divided into two kinds of installation, in order to meet the use requirements of different occasions, the specific models are as follows:
　　
2, selection parameters and selection principle
(1) the main technical parameters of bag filter are air volume, gas temperature, dust concentration and humidity. According to the process design of air volume, gas temperature, the highest value of dust concentration, according to the value of the technology performance table is slightly smaller than the principle, the corresponding dust collector model, that is, the required dust collector model.
(2) in the table of the gas consumption for the plant when the gas supply, such as the use of air compressor, the air consumption in the table should be magnified 1.5 times.
(3) compressed air consumption column, the proposed gas consumption for the model equipment, the maximum gas consumption.
3, equipment configuration and basic (see photo), our company can also according to user sites designed to meet the user requirements of the shape of dust collector.
　　
Four, ordering instructions
The products provided by our factory are not part of the dust collector three (air inlet, exhaust port, ash discharge port). Such as the main exhaust fan, non-standard pipe, heat insulation materials, air compressor, transportation equipment, installation and wire and cable, such as the user needs, I plant can be handled.
