Exhaust gas treatment system

The operating principle of the device: the exhaust gas is sent to the purification tower body through the anti-corrosion fan, and the one with the sand removal filter enters the sand removal filter first, and the casting sand particles and other wastes entrained in the exhaust gas are blocked in the filter to prevent them from entering the tower body , and then the exhaust gas is pressed into the pressure equalization chamber of the tower body, without sand removal filter, directly enters the pressure equalization chamber of the tower body through the fan, and enters the purification system of the purification tower from the bottom of the purification tower body, the exhaust gas passes through the purification system from bottom to top, and circulates The water pump pumps the neutralizing liquid from the lower part of the tower into the circulating spray system on the upper part of the two-layer purification packing and sprays it out, so that the neutralizing liquid forms a layer of water film on the surface of the packing. After contact, a neutralization reaction occurs, so as to achieve the purpose of purifying the exhaust gas.

The neutralized gas passes through the gas-liquid separation layer, and the water mist is blocked in the tower, and the purified gas is discharged out of the tower through the air outlet. The liquid on the liquid film flows into the center under the action of gravity and starts the next cycle.
