Dust removal program of coke plant dust collector


Dust removal plan of coke plant dust collector. The dust removal point of the coke plant ground station dust collector includes the top smoke guide hole, the side of the coal loading truck, the coke blocking door, the coke guide grille, and the top of the coke quenching car. After the dust is collected through the dust collecting hood and pipes, the connected trolley, coal loading coke pusher and coke blocking car are connected to the top smoke guide car, through the ventilation slot, the thermal storage spark trap is introduced, and then the low pressure is passed through the long bag. Pulse bag type dust collector, the purified clean gas is discharged into the atmosphere through the fan and the chimney. The dust collected by the bag type dust collector is transported out of the vehicle through the star ash discharge valve, the embedded scraper, the middle ash bin, and the dust-free loading machine. .


Dust removal program of coke plant dust collector


1. The flue gas discharged from the top smoke guide hole is retained on the coke oven top coke oven side, and is equipped with a movable ventilation slot supported on the coke oven column. A mobile ventilation opening device is installed on the smoke guide car and the ventilation slot The upper belt is matched and driven by the smoke guiding vehicle to direct the flue gas to the outside; the vacuum cleaner does not need additional driving equipment. The explosion-proof valve and manual wild air valve are provided on each branch of the smoke guide pipe. The wild air valve is used for manual Adjust the amount of air mixed in the tuyere to ensure that the gas concentration in the flue gas is within the safe range of the coke oven gas, and no explosion will occur. The role of the explosion-proof valve is to relieve pressure and explosion; in the event of an abnormal explosion, there is exhaust on the gas collection pipe Pipe, the smoke guiding trolley can discharge air when the dust removal system fails. The combustion chamber is set in the design. The flue gas generated by coal loading enters the combustion chamber of the smoke guiding trolley, and after combustion, it no longer contains flocculent flue gas and stickiness Tar flue gas. Therefore, technical problems such as filter bag dust removal and ash hopper dust removal during tamping coke oven dust removal have been completely solved, ensuring long-term effective operation of the tamping coke oven coal dust removal system.


Coking plant dust collector dust removal plan 2. The coke exit flue gas capture hood is fixed and moved on the coke blocker. Together with the coke blocker, a mobile ventilation slot is added on the side of the third track of the coke blocker. Ventilation opening device; on the frame of the dust removal ventilation hood. The dust collection hood and mobile ventilation exhaust device and running platform running on the coke side coke blocker track, the third track outside is driven by the coke blocker without additional The driving equipment introduces the smoke and dust generated during the coking unloading process into the ventilation slot, and pumps the smoke and dust to the baghouse dust collector at the ground dust removal station for purification treatment.


Coking plant dust collector dust removal plan 3. Smoke collection on the machine side furnace door requires designing a separate flue gas collection hood and corresponding extraction device to collect the fume that escapes from the machine side furnace door. Similarly, the mobile ventilation tank can completely solve the problem of dust removal at this kind of mobile dust generation point. At the tail of the coke pusher, parallel to the existing coke pusher grinding channel, a movable ventilation slot extending in the direction of the coke oven is provided, and a collection cover is provided directly above the door of the coke pusher and the collection cover passes through the air duct. And, it leads to the tail of the coke pusher. At the same time, in order to increase the effect of the furnace mouth and the collection of flue gas, a flue gas shroud is set above the furnace mouth, which can completely introduce the flue gas into the collection cover. The mobile exhaust device is installed on the rack at the end of the coke pusher. The mobile exhaust device is docked with the mobile exhaust tank, and the flue gas is introduced into the mobile exhaust tank and reaches the ground dust removal station for processing. The mobile ventilation unit on the mobile ventilation tank is driven by the pusher, without adding additional driving equipment.


Dust removal plan for coke plant dust collector 4. Dust removal ground station and flue gas treatment system 1) The flue gas generated by coke removal of bag dust collector through mobile vents (hoods) and three mobile ventilation slots enters the dust collector through dust removal air ducts . The vacuum cleaner uses a long-bag low-pressure pulse vacuum cleaner. This equipment represents a more advanced dust removal technology with high purification efficiency (up to 99%), a small floor area, and a low dust removal pressure, only 0. 15 ~ 0. Under the pressure of 25 MPa , Widely used in metallurgy, building materials, chemical industry, textile and other industries. Coke oven coal dust removal technology also has a good application. Coke oven flue gas, filtering wind speed can reach 1. 0 ~ 1., 2 meters / minute, coking The concentration of flue gas after purification by the factory bag filter will be lower than 20 mg / m3, which is lower than the national allowable emission requirements.

Because the smoke collected by the top smoke guide car contains a small amount of tar, the smoke collected by the coke blocking car often contains sparks, and some protective measures need to be taken to avoid adversely affecting the filter bag:


(1) Adopt polyester needle-punched felt containing conductive fibers, and water-proof and oil-proof treatment to prevent smoke from being caused by static sparks. Because the flue gas temperature is between 80-120 ℃, the working temperature of the filter bag is ≤120 ℃.


(2) Pre-spraying measures: Before installing a new cloth bag or after long-term maintenance, run the coke blocking and dust removal for a period of time (about 3 days). The flue gas (mainly composed of coke powder) generated by the coke blocking and dust removal is deposited on the surface of the filter bag. One layer of tar powder, so that when the top smoke guiding trolley is opened again for dust removal, the surface of the filter bag will not contact with the tar, so as to avoid sticking to the filter bag. Experience has proven that the coal-loaded coke dust remover can effectively avoid tar sticky bags phenomenon.


(3) Because the coal charging and decoking time is only about 8-10 minutes, in the case that the dust collector does not have soot filtering, the pulse cleaning can be effectively improved by computer programming.


(4) Before the flue gas enters the dust collector, a set of regenerative spark trap is set. The spark trap is provided with a large number of cooling plates. The flue gas collected by the trap enters the spark trap through the dust removal duct, and then enters the bag type dust collector for purification. The cooling plate in the spark trap traps heat in advance. Coke powder and sparks protect the filter bag in the dust collector from burning. At the same time, due to coke oven flue gas, dust removal and cold and heat alternate frequently. Another role of the regenerative spark trap is to balance the effects of hot and cold flue gas: When hot flue gas passes through The cooling plate cools the flue gas. When the cold air is drawn out, the cooling plate heats the air.

Coking plant dust collector dust removal program uses a long-bag low-pressure pulse dust collector, online dust removal, offline maintenance. There is a manual air shut-off valve at the entrance and exit of each box. When the resistance of the equipment rises to a predetermined value, the control system will The pulse valve in the first box is started in turn, and the filter bags in the box are blown row by row. After blowing, if the resistance of the system is still not lower than the predetermined value, the next box will be automatically executed, thereby gradually circulating. Working principle of bag filter
