Product Description

In the process of plate rolling, a large number of fallen iron oxide powder, cooling water vapor and burning ash of lubricating oil are produced, and a large number of harmful smoke and dust are produced between mill stands. The main components of flue gas are FeO, Fe2O3, H2O, lampblack and so on. In order to reduce and eliminate the pollution of these harmful substances to the environment and improve the operating conditions, a smoke and dust removal system is set up on the finishing mill stand, so that all the smoke generated by the rolling mill can be purified by inhaling the plastic-fired plate dust collector in the closed smoke hood. The dust removal system consists of a dust cover, a manual control valve, an air duct, a plastic-fired plate dust collector, a fan, a muffler and a chimney. There are several dust removal points in the exhaust and dust removal system of finishing mill. The designed air volume at each point is 10000-60000. The dust removal system flow is as follows: the dust-containing gases collected from the dust source points by the dust-collecting cover enter the dust collector through the pipeline, and the dust is separated by the plastic-fired filter plate. The purified gas is discharged into the atmosphere through the exhaust chimney after passing through the fan and muffler. The dust adhering to the surface of the plastic burning plate is blown back by the electromagnetic valve and falls into the dust hopper of the dust collector. Then it is discharged by the screw conveyor and the rotary ash discharging valve, which is recycled and treated uniformly. Because the fine dust, especially the dust below 5um, is the most harmful to human health, in this case, a high requirement will be put forward for the dust collector, which requires that the dust collector has the characteristics of high dust collection efficiency, small size, convenient maintenance and long service life. Plastic-fired plate dust collector is a new generation of dust collector developed to meet these requirements. Plastic-fired board dust collector has the unique advantages of small size, high efficiency, convenient maintenance, moisture absorption and high moisture content of dust, oil and fiber dust filtering, which is incomparable with electrostatic precipitator and bag filter. Because the plastic-fired plate dust collector is a kind of dust collector which uses plastic-fired plate instead of bag filter components, it is suitable for the occasion of water and oil in gas. The working principle of bag filter is that the dust-containing gas enters the hopper through the intake port or the filter bag chamber through the open flange opening. The dust-containing gas filters through the filter bag to enter the clean air chamber, and then exhausts 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 dust 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. With the reverse direction of the air flow, the dust will be shaken off to achieve cleaning. The purpose of gray. Principle of type selection (1) The main technical parameters of bag filter type selection are air flow, gas temperature, dust concentration and humidity. According to the maximum value of air volume, gas temperature and dust concentration in process design, and according to the principle that the value is slightly less than that in technical performance table, the corresponding type of dust collector, that is, the type of dust collector needed. (2) The amount of air consumption in the table is the case of centralized air supply in factories, such as when air compressor is used alone, the amount of air consumption in the table. To magnify 1.5 times. (3) In the column of compressed air consumption, the proposed gas consumption is the maximum gas consumption of this type of equipment.
