Bag filter for coke oven in coking plant

Coking plant dust collector、Bag filter for coke oven in coking plantDesign principles:
Firstly, the system should operate reliably and stably for a long time to avoid faults such as dust accumulation in the air duct and air flow attenuation caused by high resistance of the dust collector bag. The technology used can withstand practical tests and can operate reliably and stably for a long time.
2. Optimize and select various technical parameters of the dust removal system to achieve good smoke and dust capture and purification effects with low investment. Save energy and reduce operating costs.
3. Adopt mature technology and not simply copy other dust removal modes. Taking into account the equipment, factory conditions, and long-term planning goals of the demand side company, comprehensively consider the design scheme to achieve good results.
4. It does not affect the original process and the operation methods of workers, ensuring the long-term stable operation of the dust removal system, meeting the industry's requirements for environmental protection and meeting standards.

Technical parameters related to dust collectors in coking plants and bag filters for coke ovens in coking plants:

1. System design induced draft volume: 160000 m3/h

2. System full pressure: 6000Pa

3. High smoke and dust capture rate

4. High purification efficiency

5. Dust emission concentration: ＜ 10mg/Nm3

6.2 # Furnace and existing ground station connection pipeline: specifications? 1500mm steel pipe wall thickness: 5mm

7. Electric valves: (3 units) Interface: compatible with existing pipelines Drive mode: electric

Installed at the front end of newly added pipelines and existing dust removal stations, the function is to facilitate process switching, allowing the two dust removal ground stations to be used one-on-one or in a one to two manner.

8. Extraordinary valve: (1 unit) Diameter: DN1000mm Drive mode: electric

Installed on the balance valve pipeline at the entrance of the newly built dust removal station, the balance is closed during coal loading or coke pushing work; After loading coal or pushing coke, open the balance valve to suck in air and maintain system pressure balance.

9. Explosion proof bag filter: one unit

Function: Under the action of the fan, it is used to filter and purify the dusty flue gas sucked in from the machine side furnace door vacuum hood to control pollution. The dust collector mainly consists of an upper box, a middle box, an ash hopper, inlet and outlet air ducts, filter bags and blowing devices, ash unloading devices, brackets, platforms, etc.

10. Chimney: 2000mm H=25000mm one

11. Pre spraying device: High pressure air is used to spray clean dust into the inlet pipeline of the bag filter, so that the dust is evenly coated on each filter bag, preventing tar containing coal loading flue gas from adhering to the filter bag, causing the filter bag to lose its filtering ability and cannot be used. The spraying powder shall be sent by Party A into the spraying ash bin.

The overall design concept for the design and manufacturing of the coal loading and pushing coke dust removal system for the renovation of bag filters for coke ovens in coking plants

1. This project adopts a set of ground dust removal stations, namely: 1 # and 2 # furnaces use one set of ground dust removal stations, which can save investment.

To save civil engineering investment, the dust collector should be arranged on the ground, and an electric control room and a fan room should be set up next to the ground dust removal station.

3. The dust collected by the dust removal system does not need to be humidified, and a dust suction port is installed at the ash discharge point. When unloading the ash to the ash truck, there will be no dust generated.

4. The dust removal fan is arranged indoors, and the speed control of the dust removal fan adopts the frequency converter speed control method

5. The dust removal system does not have a separate air compressor. The compressed air used for the dust collector is delivered to the boundary of the dust collector by Party A, and a gas storage tank should be installed in the dust removal area.

6. The smoke guide vehicle for coal loading and dust removal is equipped with a waste gas combustion device, and the coke oven gas pipe for waste gas combustion is constructed by our side for the dust removal system.

7. The dust removal system is equipped with spark extinguishing and cooling devices, as well as pre spraying devices.

8. The dust removal system takes measures to prevent the occurrence of bag blockage in the dust collector.

9. Reliable measures for handling coal loading on the side of the coke oven machine, and the effectiveness of smoke and dust treatment during coke pushing and coal loading.
