Environmental dust

Description: Another notable feature of environmental dust collector is the use of central box intake air; The flue gas flows through the separation plate evenly, which not only improves the filtration efficiency, but also makes the reverse air flow not produced during the cleaning, thus improving the cleaning effect.
The environmental protection dust collector adopts the technology of split chamber air stop pulse jet dust removal, which overcomes the disadvantages of conventional pulse dust collector and split chamber reverse dust collector. It has strong dust removal capacity, high dust removal efficiency, low emission concentration, small air leakage rate, less energy consumption, less steel consumption, less land area, stable and reliable operation, and good economic benefits. Suitable for metallurgy, building materials, cement, machinery, chemical, electric power, light industry dust gas purification and material recovery.
We know that coke ovens produce a lot of high-temperature dust with sparks in the process of coking. If this dust is not cooled and the spark is not eliminated into the bag dust collector, it will produce combustion and explosion. In order to reduce the dust temperature and reduce the open flame, a cooler is set in front of the dust collector in the dust removal system. Before the dust enters the bag dust collector, it is cooled by a cooler and the sparks are separated. In addition to cooling the high-temperature dust quickly, the regenerative cooler has a special function, that is, the dust with sparks is extinguished in the cooling process through the cooler, but there are still residual sparks into the bag dust collector with the dust. And the structure of the flame retarder pulse dust collector is designed. When the dust with residual spark enters the dust collector, it is first obstructed by the fire retardant partition, and the open fire is blocked off. It plays a secondary separation and directly enters the ash bin, and does not contact with the cloth bag, which eliminates the hidden danger of the cloth bag explosion. This increase barrier plate, spark secondary separation structure form, other pulse environmental precipitator is not available.
Another characteristic of coke oven flue gas dust is hard, sharp surface. This is especially true for larger particle size coke. However, these larger particles of dust and dust with residual sparks are separated by the barrier board twice and fall directly into the ash bin, and the smoke powder into the bag is very fine, which greatly improves the service life of the filter bag. The bag should be changed in the past six months or so, and with this structure, the service life of the filter bag can reach more than 1.5 years. Generally there is no problem for two years.
Another notable feature of this type of fire retardant pulse environmental dust collector is the use of air inlet in the middle box; The flue gas flows through the separation plate evenly, which not only improves the filtration efficiency, but also makes the reverse air flow not produced during the cleaning, thus improving the cleaning effect.
Due to the explosive existence of coke oven environmental dust collector, in addition to the above special structure in the structure form, the dust collector box plate is also equipped with reinforcing bars, and each chamber is designed to be independent and completely separate structure, in order to reduce the probability of hidden dangers and improve the dust removal effect of dust collector. Because of the particularity of coke oven dust, the design of coke oven bag dust remover adopts the above special structure, which makes the fire retardant pulse dust collector more professional and adaptable, so it is widely used in the coke oven ground dust removal system.
