560m2 Baghouse Dust Collector For Asphalt Plant

product description

The negative pressure airflow generated by the draught fan shall enter into the flow sinking device through the inlet of the dust remover. After the dust particles collide with the guide plate, the large particles will sink first, and the dust mixture containing tiny particles shall be filtered and separated by the separation effect of the filter element in the dust removal chamber. when the dust goes through the filter element, it will be hindered on the surface of the filter element. When the hindered smoke dust constantly deposit on the surface of the filter element, the differeintal pressure between the interior and exterior of the filter element will keep on enlarging. When the differential pressure reaches the preset value, the magnetic valve controlling the compressed air shall be released to eject the compressed air in the air package from the outlet of the ejecting pipe. As induced by the Venturi, the ambient air as much as several times of the primary wind shall be sprayed to the surface of the filter element, under the high pressure airflow, the dust particles deposited on the filter element will break away from the surface of the filter element and fall into the ash drum, so that the surface of the entire filter element can be cleaned.

Techinal parameters

Equipment advantages

1. The cleaning intensity is higher, and the air inlet and outlet are evenly distributed.
2. The dust collection efficiency is higher, up to 99.8%.
3. The service life of the filter bag is effectively extended.

Details

1. The structure of Xinchen XMC sub-chamber pulse bag filter:
△ Box body: bag room, pre-cleaning room, clean air room, perforated plate, filter bag, filter bag frame, the box body is designed to withstand a pressure of 9000Pa, which is greatly improved compared with the conventional bag filter;
△ Injection system: main air pipe, injection pipe, pulse valve, control device, use PLC or special pulse program controller automatic control device, according to the nature of dust and working environment, reasonably adjust the cleaning cycle and pulse spray time to maximize the dust collector Ideal cleaning effect;
△ Ash hopper and ash discharge part: divided into direct connection form, ash hopper is connected with ash discharge valve through conveying equipment;
2. According to the change of working environment, Xinchen XMC sub-chamber pulse bag filter is matched with solenoid valves of different specifications to adapt to a variety of complex dust removal environments. Even in the particularly cold northeast and northwest regions or when the flue gas is below zero, the heat preservation and heating device needs to be added, and the shell only needs to be changed slightly without replacing new equipment, which saves a lot of investment costs for users.
3. Reasonable box structure and automatic control series effectively improve the working efficiency of the XMC sub-chamber pulse bag filter. During the working process, the dust-containing gas enters the expanded ash hopper of the dust collector for pre-collection, and is evenly distributed through the deflector. Between each filter bag, the dust is retained on the outer surface of the filter bag. In order to make the equipment resistance not exceed 1200Pa, the high-pressure gas is pulsed through the solenoid valve, so that the compressed air (0.5~0.7MPa) in the air bag is blown by the hole of the nozzle The sprayed (called primary air) induces several times the surrounding air (called secondary air) through the venturi tube into the filter bag and rapidly expands in an instant, and shakes off the dust along with the opposite direction of the airflow to achieve a clean dust. purpose.
4. The filter bag of Xinchen XMC sub-chamber pulse bag filter is generally made of polyester needled felt, and the allowable temperature can reach 120℃. If the filter bag adopts the high temperature of Metas above the allowable temperature of the filter material, the exhaust gas enters the dust collector. Cooling measures should be taken before. This series of dust collectors has nine specifications: 60-2, 60-3, 60-4, 60-5, 60-6, 70-5, 70-6, 70-7, 70-8. The specific performance parameters are as follows:
