Coking plant special filter adopts domestic advanced coal combustion method, and makes the coal dust collected into coke side dust dry dedusting ground station of coal dust removal technology. It realize the coal dust catcher, roof and transfer station flue gas, flue gas temperature regulation control, integration of flue gas purification and utilization in the process of coke pushing collected in coke powder on the surface of the filter bag to prevent coal smoke contains tar and water vapor in the process of bonding filter bag, ensure the equipment safe and stable operation for a long time.
    Coal dust removal system is composed of two parts, top part with soot dust catcher device, coal car hood by activities, guide tube, flue gas regulating valve, air control valve, safety valve, dust suction system expansion connector, etc. Through the telescopic connector open dust flap valve on the main interface. Coal from flue gas mixed with quantitative air, when the dust to the main and the coke side precipitation is an organic whole to ground stations purification treatment. The other part is pushing coal smoke purification station, one in the ground station with fan, an off-line pulse bag filter, the exhaust machine with hydraulic coupling unit, dust recovery coke powder ash conveying device and the corresponding electrical, instrumentation equipment, such as compressed air and cooling water system.
    Coking plant special filter adopts low-pressure soot cleaning method, filter bag injection procedures and control time is controlled by a PLC electrical system, such as collection of dust can be delivered or pull to the yard. Dust removal system design of air is 60000 m3 / h, in ensuring safe and reliable operation of the dust removal effect and the dust removal system conditions, according to the dust removal system resistance and the running situation of coke oven, determine the best air volume adjustment.
Coking plant dedicated dust catcher：
1, the coal dust by non combustion way against the into a lot of air, make the combustible dust component content is far lower than the lower explosive limit, to ensure the dust into the dust removal system is safe;
2, coke side collected dust removal system is dry gas and coke powder physical effectively absorb the harmful elements in coal dust, tar and moisture, do not need to consider the heat preservation of dust removal equipment, heating and condensation prevention measures;
3, using low pressure tube jet pulse filter greatly improves the dust ash removal ability, bonded to prevent dust filter material, and increase the system resistance;
4, the system design ability to give full play to the purification of ground dust removal equipment, through the special fan and piping system design and control of coal dust and the coke side dust into a system, can greatly save investment.
