Waste gas treatment device

Abstract

The invention relates to a waste gas treatment device, and belongs to the technical field of environmental protection equipment. The device comprises a turbulent mixing dust removal device, a drying device, a fore-lying filter, a zeolite rotating wheel concentration device, a fan I, a chimney, a heat exchanger, a rotary RTO incineration device and a fan II. According to the invention, the turbulent mixing dust removal device arranged in front of the fore-lying filter pre-treats waste gas to remove the particulate matters in the waste gas, and the residual dust in the waste gas is filtered through the fore-lying filter, so that the situation that the filtering material of the fore-lying filter is frequently replaced can be avoided, and the blockage of the zeolite rotating wheel concentration device due to the poor filtering effect of the fore-lying filter can also be avoided; the gas treated in the zeolite rotating wheel adsorption area is used as the cooling gas of the cooling area, sothat the situation that the adsorption capacity of the zeolite rotating wheel is reduced when the zeolite rotating wheel reaches the adsorption area to cause the over-standard of the harmful substances in the waste gas after the zeolite rotating wheel reaches the cooling area to adsorb a certain organic harmful substances due to the fact that original waste gas is used as the cooling gas is avoided.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a waste gas treatment device. Background technique [0002] Due to the increasingly serious environmental pollution, the emission indicators of organic waste gas are becoming more and more stringent, and the demand for environmental protection equipment is also increasing. [0003] At present, the most common treatment equipment on the market is a device formed by a zeolite rotor combined with a combustion furnace. Because there are many dust particles in the exhaust gas, the device of the zeolite rotor combined with a combustion furnace is usually only filtered by an ordinary pre-filter device , there is no effective pretreatment of the exhaust gas, resulting in frequent replacement of the filter material in the later purification device, which is time-consuming and laborious, and it is easy to cause the zeolite runner to be easily blocked....

Problems solved by technology

[0003] At present, the most common treatment equipment on the market is a device formed by a zeolite rotor combined with a combustion furnace. Because there are many dust particles in the exhaust gas, the device of the zeolite rotor combined with a combustion furnace is usually only filtered by an ordinary pre-filter device , there is no effective pretreatment of the exhaust gas, resulting in the frequent replacement of filter materials in the later purification device, which is time-consuming and laborious, and it is easy to cause the zeolite runner to be easily blocked

At the same time, the cooling air used in the cooling zone of the zeolite runner in the current zeolite wheel concentration treatment device is basically untreated raw waste gas, so that when the zeolite runner passes through the cooling zone, it will absorb some harmful substances, and when it reaches the adsorption zone, Its adsorption capacity has decreased, which will inevitably cause relatively more harmful substances in the gas discharged from the adsorption area.
