Description

Mould board dust remover that burns

Technical Field

The utility model relates to a mould and burn board dust remover belongs to dust collecting equipment technical field.

Background

In order to protect the environment, the state has strict regulations on the exhaust gas discharged by production enterprises, and the dust content in the discharged gas must meet the requirements of emission standards. The prior pelletizing process of iron and steel enterprises generally uses a production process of a pellet chain grate rotary kiln, materials are firstly dried, wet-milled and then enter the chain grate rotary kiln through a dryer and a wet mill, the dried and wet-milled dust-containing flue gas is directly discharged into the atmosphere, a large amount of water vapor and bentonite are carried in the discharged dust-containing flue gas, the temperature of the discharged dust-containing flue gas is generally about 100 ℃, the bentonite carried in the dust-containing flue gas has adhesive property, and the dust content in the dust-containing flue gas is seriously overproof. The existing dust-containing flue gas treated by the steel pellet process is commonly subjected to water dust removal and bag-type dust removal, because the temperature of the discharged dust-containing flue gas is about 100 ℃, water used in the water dust removal is likely to be evaporated to form white smoke plume and bentonite particles cannot be effectively discharged, and in the bag-type dust removal mode, because the bentonite in the dust-containing flue gas has adhesiveness, the cloth bag is easily and directly stuck, the pressure difference of an integral dust removal system is increased, and the dust removal is ineffective.

The existing domestic air dust removal technology industry also uses a plastic burning plate dust remover for removing dust, and the dust remover generally comprises a dust remover shell, a plastic burning plate filter element, a high-pressure air bag, a fan, a dust removal partition plate and other parts. When the dust removal device is used, dust-containing smoke enters from the dust inlet pipe, the dust-containing smoke is blown to the surface of the dust removal partition plate for primary dust removal, then bypasses the dust removal partition plate to enter the plastic burning plate for secondary dust removal, purified clean air is discharged from the inner cavity of the plastic burning plate through the air outlet of the dust remover shell, dust is blocked and attached to the outer surface of the filter element of the plastic burning plate, compressed air is sprayed to the inner cavity of the filter element of the plastic burning plate by the spraying pipe periodically through a compressed air bag, and under the reverse blowing action of strong airflow, dust attached to the outer surface of the filter element of the plastic burning plate is separated and falls to the dust removal device for centralized collection and treatment. Because contain bentonite in the flue gas that drying-machine and wet mill got rid of, the cohesiveness of bentonite can make and pile up a large amount of bentonite on the dust removal baffle, and then plug up into the dirt pipe, increase the pressure differential of dust remover casing and air inlet, not only reduce the dust removal effect, increase energy consumption moreover, the fan setting is outside the dust remover casing simultaneously, and it rotates the in-process, and sound is great, forms noise pollution, influences operating personnel.
