The dedicated dust collector for coking plants adopts the domestic non combustion method of coal loading, and the collected coal loading dust enters the coal loading dust removal technology of the dry dust removal ground station on the coke side. Industrial dust collectors achieve the capture of coal loading smoke and dust, transfer of flue gas from the furnace top and ground station, temperature regulation and control of flue gas, and integration of flue gas purification. The dedicated dust collector for coking plants uses the coke powder collected on the surface of the filter bag during the pushing process to prevent the smoke and dust from containing tar and water vapor from sticking to the filter bag during the coal loading process, ensuring the long-term safe and stable operation of the equipment.
The coal loading and dust removal system consists of two main parts. The top of the furnace is a dust removal and coal loading vehicle with a smoke and dust collection device. The smoke and dust suction system is composed of a movable hood, smoke guide pipe, smoke control valve, air control valve, safety valve, expansion connector, etc. Open the interface flap valve on the dust collection main pipe through the telescopic connector. The smoke emitted during coal loading is mixed with a certain amount of air and sent through the dust collection main pipe to the integrated dust removal ground station with coke side dust removal for purification treatment. The other part is a ground station that combines pushing coke and coal into one for smoke and dust purification. The ground station is equipped with fans, offline pulse bag filters, smoke exhaust fan units with hydraulic couplings, dust collectors, coke powder recovery and ash conveying devices, as well as corresponding electrical and instrumentation equipment, compressed air and cooling water systems.
The dedicated dust collector for coking plant adopts low-pressure dust cleaning method, and the filter bag spraying program and control time are controlled by the electrical PLC system. The recovered dust can be taken out or transported to the material yard for processing. The dust removal system is designed to handle an air volume of 60000m3/h. Under the condition of ensuring the dust removal effect and safe and reliable operation of the dust removal system, the optimal air volume is adjusted and determined based on the resistance of the dust removal system and the operation of the coke oven.
Advantages of specialized dust collectors for coking plants:
1. Coal loading and dust removal use non combustion methods to mix a large amount of air, so that the combustible component content in the smoke and dust is far below the lower explosive limit, ensuring that the smoke and dust entering the dust removal system is safe;
2. The coke side dust removal system collects dry coke powder and gas, which can effectively absorb harmful components, tar, and moisture in coal loading smoke and dust, without considering measures such as insulation, heating, and anti condensation of dust removal equipment;
3. The use of low-pressure pipe jet pulse dust collector greatly improves the dust cleaning ability of the dust collector, prevents dust from sticking to the filter material, and increases system resistance;
