What kind of dust collector is used for coke oven gas?
Thread Content
The coke oven gas from the vertical furnace contains a lot of dust. What kind of dust collector should I choose for dust removal?
It also depends on the dust removal temperature and whether it has been cooled. The most commonly used one is the cyclone dust collector, which has a simple structure, is cheap and is highly efficient.
The coke oven gas coming out of the vertical furnace has not been cooled and has a temperature of about 160 degrees Celsius. The key is whether the induced draft fan can be installed after the cyclone dust collector and in front of the Venturi tower. Will tar stick to the cyclone dust collector?
The coke oven gas from the furnace first passes through a Venturi tower and is washed and cooled with hot ammonia water to remove tar. Then it goes to the cyclone tower and is washed and cooled with cold ammonia water to remove tar. It is then extracted with an induced draft fan. The dust content in the coke oven gas is high, and a dust removal device needs to be installed between the furnace and the Venturi tower for dust removal. Can I use a cyclone dust collector? If the fan can go before the cyclone dust collector, there is no need to doubt it. The key is to extract air after the cyclone dust collector. I wonder if the cyclone dust collector can still work?
The working temperature of the electric tar collector is better when it is below 120°C. Will the high tar content of our coke oven gas burn the corona pole and cause a fire? What kind of dust collector do other coking plants choose?
The reason why we need to remove dust is that the tar produced during water washing contains a lot of dust and the oil-water separation effect is not good, so we want to remove dust first and then wash with water.
This is a very good question. It would be great if there is someone who can provide a project-style report for reference.
