The dust collector at the coke side ground station of the coking plant is mainly used to stop and manage the smoke and dust generated during the coke quenching process. A combined dust removal unit consisting of a thermal storage cooler and an offline pulse type bag filter is installed in front of the bag filter, with a post dust collection rate of over 80%.

technological process

During the consumption process of coke oven in coking plant, the smoke and dust are sucked into the dust removal main pipe through the conduit, and the large particle dust is separated in the regenerative cooling fire extinguisher (gravity dust collector) and directly flows into the ash hopper. After the smaller dust enters the middle box of the bag filter evenly, it adsorbs on the surface of the filter bag. The dust containing gas enters the clean air chamber after being filtered by the filter bag and is discharged into the atmosphere through the exhaust pipe.

Composition of ground dust removal station

It consists of connecting pipelines, coolers, low-pressure pulse bag filters, pre spraying systems, compressed air systems, ash conveying systems, ventilation units, control rooms, distribution rooms, PLC rooms, and chimneys.

Pre spray installation

The bag filter is equipped with pre spray installation, which evenly adsorbs the coke powder onto the dust collector bag along with the airflow, thereby preventing tar in the flue gas from directly contacting the bag; To avoid condensation inside the dust collector of the coking plant, the dust collector body and silo are equipped with insulation; The filter bag adopts filter material; Grounding installation for dust removal system; Bag dust collectors and intermittent high-temperature smoke and dust cooling flame arresters are both equipped with safety explosion-proof installations
