Product Description
DMC Pulse Single Machine Bag Precipitators
I. overview
DMC type pulse single machine bag filter is a small bag filter designed by our company after digesting and absorbing advanced technology of similar products abroad. This kind of filter uses high pressure (0.5-0.7 MPa) high flow pulse valve to spray the bag one by one to clean the dust. Compared with other single machines in China, it has the characteristics of high kinetic energy and high efficiency of cleaning the dust. It has small size, light weight, simple and compact structure, easy installation and easy maintenance (external filter type). It is widely used in the dust-containing gas purification and treatment system of building materials, metallurgy, mining, coal, non-metallic mineral superfine powder processing and other industries. It is an ideal equipment for environmental protection and dust removal.
II. Structure and Working Principle
1. The structure of single bag filter is composed of the following parts:
(1) Box body: including bag chamber, air purification chamber, porous plate, filter bag, filter bag skeleton, overhaul door, box body design pressure 5000Pa.
(2) Injection system: including main pipe, injection pipe, pulse valve and controller.
(3) There are two forms of air intake and ash removal: one is the standard ash bucket type, the other is the open flange type at the top of the reservoir.
2. Working principle:
Dusty gas enters the filter bag chamber through the intake port or through the open flange opening. Dusty gas filters through the filter bag into the clean air chamber, and then passes through the exhaust port of the clean air chamber and is discharged by the fan. Dust accumulates on the outer surface of the re-filter bag and increases continuously, which makes the resistance of the bag filter increase continuously. In order to make the resistance of the equipment not exceed 1200Pa, the bag filter can continue to work, it is necessary to remove the dust on the filter bag regularly. Cleaning ash is a pulse valve which is started by the programmable controller in a regular sequence, so that the compressed air (0.5-0.7 MPa) in the air chamber can be ejected from the nozzle hole (called primary air) and the surrounding air (called secondary air) which is several times larger than primary air can be induced by the Venturi tube into the filter bag and rapidly expands in an instant, accompanied by the reverse direction of the air flow to shake off the dust, so as to achieve the purpose of cleaning ash.
Three. Type selection
1. Model description:
The single machine has 12, 24, 36, 48, 60, 72, 84, 96, 104, 120 specifications, of which each specification is divided into two installation forms to meet the use requirements of different occasions.
2. Type selection parameters and principles:
(1) The main technical parameters of bag filter selection are air flow, gas temperature, dust concentration and humidity. According to the maximum values of air volume, gas temperature and dust concentration in the process design, according to the principle that the values are slightly smaller than those in the technical performance table, the corresponding type of dust collector is the type of dust collector needed.
(2) The air consumption in the table is 1.5 times greater than that in the case of centralized air supply in the factory, such as when air compressors are used alone.
(3) In the column of compressed air consumption, the proposed gas consumption is the maximum gas consumption of this type of equipment.
3. The shape and foundation of the equipment (see the attached figure). Our company can also design the dust collector according to the user's site conditions.
