The beneficial effects of the utility model are as follows: a water spray device, a dewatering and demisting layer device, a high-pressure spray device, a biological filter bed, and a gas purification device are successively installed in the casing from left to right, and the outlet end of the gas purification device is connected with a connecting row The wind device, connected to the exhaust device is driven by the fan, the casing is provided with an inspection door, the water spray device is provided with a filter layer, the lower end of the filter layer is provided with a circulating water tank, and a circulating water pump is provided in the circulating water tank, and its structure design is simple Scientific, energy saving and environmental protection, exhaust gas purification thoroughly.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a structural schematic diagram of another direction of the utility model.

Detailed ways:

As shown in Figures 1 and 2: the utility model includes a housing 100, a water spray device 1, a water and mist removal device 2, a high-pressure spray device 3, a biological filter bed 4, a gas purification device 7, and an exhaust device 6 A water spray device 1, a water and mist removal layer device 2, a high-pressure spray device 3, a biological filter bed 4, and a gas purification device 7 are successively installed in the housing 100 from left to right, and the outlet end of the gas purification device 7 is connected with Connected to the exhaust device 6, which is driven by the fan 8, the housing 100 is provided with an inspection door 9, the water spray device 1 is provided with a filter layer 5, and the lower end of the filter layer 5 is provided with a circulating water tank 12, which circulates A circulating water pump 11 is provided in the water tank 12 . A high-pressure spray system main controller 12 is installed at the lower end of the housing 100 .

The high-pressure spraying device 3 and the biological filter bed 4 can be more than one set.

There are more than two inspection doors 9 .

The exhaust gas of the utility model enters from the left inlet, and is discharged through the water spray device 1, the dewatering and demisting layer device 2, the high-pressure spray device 3, the biological filter bed 4, the gas purification device 7, and the exhaust device. Its structure design is simple and scientific , using biological waste gas treatment, energy saving and environmental protection, and thorough purification of waste gas.

1. The processing steps of this embodiment are as follows:

Exhaust gas→water spray device 1→filter layer 5→water spray device 1→water and mist removal layer device 2→high pressure spray device 3→biological filter bed 4→high pressure spray device 3→biological filter bed 4→gas purification device 7 →Fan 8→Emission.

2. Working principle:

After the exhaust gas passes through the pretreatment process of dust removal and humidification, it passes through the biological filter bed 4, and the exhaust gas is transferred from the gas phase to the water-microbial mixed phase, and is decomposed by the adsorption and metabolism of the microorganisms fixed on the filter material, and transformed into biomass and Inorganic substances are purified through the gas purification device 7, so as to be discharged up to the standard.

The biological waste gas treatment system is mainly composed of three parts: water spray device 1, water and mist removal layer device 2, high-pressure spray device 3, and gas purification system. The exhaust gas is firstly sprayed with water, and the larger particles that are easily soluble in water are mixed with water and then flow into the circulating water tank, so as to achieve the effect of dust removal. The pretreated exhaust gas enters the high-pressure spray device 3 through the dewatering and mist-removing layer, and the spraying amount of the agent in the high-pressure spray device 3 is controlled through PLC programming design, so that the exhaust gas and the agent are fully contacted, and the gas phase is transformed into the liquid phase. Purpose. The waste gas dissolved in the water phase enters the biological filter bed 4 and is absorbed and metabolized by the microorganisms fixed on the filter material to be decomposed. The purified waste gas passes through the gas purification device 7 to ensure that the gas is discharged up to the standard.

The utility model has wide application range, mature technology, convenient operation and low processing cost.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
