The dust collector at the coal coking ground station adopts a low-pressure dust cleaning method, and the filter bag injection program and control time are controlled by an 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 conditions of dust removal effect and dust removal system operation, the air volume is adjusted and determined based on the resistance of the dust removal system and the operation of the coke oven.

The dust collector of the coal coking ground station adopts the excellent non combustion method of coal loading in China, and the collected coal loading dust enters the coal side dust removal dry dust removal ground station's coal loading dust removal technology. It realizes the capture of coal loading smoke and dust, the transfer of smoke from the furnace top and ground station, the regulation and control of smoke temperature, and the integration of smoke purification. The dust collector of the coal coking ground station 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 long-term 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, 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.

Advantages of dust collectors in coal coking ground stations:

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 is far below the lower explosive limit, and the smoke enters the dust removal system;

2. The coke side dust removal system collects dry coke powder and gas energy to absorb the components of coal dust, tar, and moisture, without considering measures such as insulation, heating, and anti condensation of dust removal equipment;

3. The dust collector at the coal coking ground station adopts a low-pressure pipe jet pulse dust collector to improve the dust cleaning ability of the dust collector, prevent dust from sticking to the filter material, and increase system resistance;

4. The design of the dust collector for the coal coking ground station fully utilizes the purification capacity of the ground dust removal equipment. Through the design and control of the fan and pipeline system, the coal loading dust removal and coke side dust removal are integrated into one system, which can save renovation investment.
