A waste gas treatment device

Abstract

The invention relates to a waste gas treatment device, which belongs to the technical field of environmental protection equipment, including a turbulent mixing dust removal device, a drying device, a pre-filter, a zeolite runner concentration device, a fan I, a chimney, a heat exchanger, and a rotary RTO incinerator Device, blower II, the present invention pretreats the waste gas through the turbulent mixing dust removal device installed in front of the pre-filter, removes the particulate matter in the waste gas, and then filters the residual dust in the waste gas through the pre-filter In this way, it can avoid frequent replacement of the filter material of the pre-filter, and avoid the clogging of the zeolite runner concentrator due to the poor filtering effect of the pre-filter; at the same time, the present invention is to process the gas in the adsorption area of ​​the zeolite runner As the cooling gas in the cooling zone, avoid using the original exhaust gas as the cooling gas, which will cause the zeolite runner to absorb certain organic harmful substances when it reaches the cooling zone, and cause the adsorption capacity of the zeolite runner to decrease when it reaches the adsorption zone, resulting in excessive harmful substances in the exhaust gas.

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.
