The coke oven machine side dust collector produced by Jingchuang Environmental Protection Planning mainly processes the flue gas generated during coal loading and coke pushing. Pre spraying equipment is installed in front of the bag filter, and the box is equipped with valves.

Smoke and dust treatment plan for coke oven side dust collector:

1. The flue gas generated from the removal door, pushing coke, cleaning furnace door frame, and coal leveling process involved in the coke oven machine side needs to be mixed with air and captured by the dust cover installed on the pushing coke machine. It enters the dust removal pipeline through the ventilation water tank and is then sent to the pulse dust collector for purification. After purification, the clean gas is discharged into the atmosphere through the ventilation fan and chimney.

2. There are continuous dust emission detection devices installed on the chimney.

3. The ventilation trough is installed on the outer side of the track at the far end of the coke pusher, parallel to the track.

4. Due to the periodic nature of the operation of the coke oven side pushing machine, the dust removal fan is operated using variable frequency speed regulation.

5. To prevent tar from sticking to the dust collector bag in the flue gas, a pre spraying device is installed to evenly adsorb the coke powder onto the dust collector bag with the airflow, and then prevent tar from directly touching the bag in the flue gas

6. To prevent condensation inside the dust collector, the dust collector body and silo are equipped with insulation.

7. Install sound insulation equipment on the casing and front and rear pipelines of the dust removal fan; The inlet and outlet of the fan are equipped with soft connections, and the outlet of the fan is equipped with mufflers to control noise within the standard specifications.

8. Bag filter adopts continuous ash discharge; Filter bag selection of filter material; The dust removal system is equipped with grounding equipment; Bag filters and intermittent high-temperature smoke and dust cooling separation flame arresters are both equipped with explosion relief devices.

9. The above ground dust removal station consists of connecting pipelines, emergency valves, 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.

10. Flexible self collecting dust unloading equipment is selected for ash unloading.

The dust collectors on the side of the coke oven machine can achieve reasonable process, compact installation, land saving, and ultra-low emissions

The process of capturing and purifying the coking flue gas from the dust collector in the coking plant:

1. The capture hood is fixed on the coke blocking machine and moves together with the coke blocking vehicle.

2. Add a mobile ventilation groove on one side of the third track of the coke blocking machine, and the ventilation device for mobile ventilation is set on the frame of the dust removal and exhaust hood.

3. The capture hood and mobile ventilation vent equipment work on the coke blocking machine track on the coke side and the third track outside the operation platform, driven by the coke blocking machine without additional driving equipment. The smoke and dust generated during coke discharge are introduced into the ventilation duct and sucked into the bag filter of the above ground dust removal station for purification treatment.

Process characteristics of coke side dust collector in coking plant:

1. The dust emission concentration at the discharge outlet of the above ground dust removal station is less than 20mg/m3, which can ensure that the processed gas arrives safely and is below the emission standards.

2. The operating system is fully automated and controlled by microcomputers, with high operability.

3. The air duct inlet is equipped with a belt sealing port to prevent rainwater from entering the interior of the duct in summer, and snow can be cleared outside the working track of the belt car in winter, ensuring the normal operation of the belt car.

4. Switching valves are installed on both sides of the outlet pipe of the air duct to reduce air leakage and capture efficiency during dust removal in two coke ovens.

5. The bag filter of the above ground dust removal station adopts offline back blowing method, and the dust removal function of the forward dust collector can be continuously used; And it is equipped with automatic fire-fighting equipment, which can prevent sudden ignition of the bag filter, maintain the integrity of the bag filter, and advance the equipment

6. The bag filter is equipped with a pre spraying system, which hinders the impact of multi edged and sharp dust on the filter bag, and plays a role in maintaining the filter bag and extending its service life.

The above ground dust removal station for coke oven discharge is only planned for the coke discharge dust removal system. The principles followed in this technical solution are as follows:

1. The dust removal equipment produced by our company strictly complies with relevant laws, regulations, planning standards and specifications, ensuring the quality of engineering planning.

2. Advance the level of automation control, optimize operational policies, and ensure stable and long-term production work.

3. Select mature process technology and process path to achieve the level of similar work.

4. The above ground dust removal station should have a reasonable process, compact layout, and save land.

5. Fully pay attention to the comprehensive utilization of energy, reduce energy consumption, lower work costs, and advance economic benefits. When selecting equipment, consideration should be given to suitability, applicability, stability, and regional factors.
