Exhaust gas treatment system and method

Abstract

The invention relates to an exhaust gas treatment system. The system comprises a tower, a gas inlet, a gas outlet, a filter device, a water pump assembly and a water storage tank, wherein the gas inlet is located in the lower end of the tower, the gas outlet is located in the top end of the tower, the filtering device is arranged in the tower and located between the gas inlet and the gas outlet, and the water storage tank is located on one side of the tower and connected with the tower through the water pump assembly; the filter device comprises a filter screen, a guide plate and an adsorptionlayer, the adsorption layer is arranged at the upper end of the tower, the filter screen is arranged at the middle section of the tower, and the guide plate is arranged below the filter screen; a nozzle assembly is arranged between the filter screen and the guide plate, and is connected with the water pump assembly. The system is simple in structure, can effectively remove particulate matter andwater vapor in exhaust gas, and does not cause blockage to a water pump. Meanwhile, harmful gas and gas carrying particulate matter can be filtered to the greatest extent by the arrangement of the filter screen, the guide plate and the nozzle assembly, and the filter effect is improved.

Description

technical field [0001] The invention belongs to the technical field of waste gas, in particular to a waste gas treatment system. Background technique [0002] At present, the existing method of spraying exhaust gas is relatively simple in structure. The tower body is provided with an air inlet and an air outlet, and a spray device is installed in the tower body. The exhaust gas enters the tower body from the air inlet and passes through the spray device. After spraying, it is discharged from the air outlet. After the exhaust gas is treated in this way, although the particulate matter in the exhaust gas can be filtered out, the exhaust gas contains water vapor, and the exhaust gas mixed with water vapor will also pollute the atmosphere, which is not conducive to environmental protection; In addition, the traditional tower is generally equipped with a water pump, and the water pump circulates the water at the bottom of the tower for spraying, but the recycled water contains pa...

[0002] At present, the existing method of spraying exhaust gas is relatively simple in structure. The tower body is provided with an air inlet and an air outlet, and a spray device is installed in the tower body. The exhaust gas enters the tower body from the air inlet and passes through the spray device. After spraying, it is discharged from the air outlet. After the exhaust gas is treated in this way, although the particulate matter in the exhaust gas can be filtered out, the exhaust gas contains water vapor, and the exhaust gas mixed with water vapor will also pollute the atmosphere, which is not conducive to environmental protection; In addition, the traditional tower is generally equipped with a water pump. The water pump circulates the water at the bottom of the tower for spraying, but the recycled water contains particulate matter, which is easy to cause blockage of the water pump and water pipes.
