The structural schematic diagram of the whole exhaust gas treatment module 200 shown in fig. 3 mainly aims to improve the neutralization efficiency of the whole exhaust gas in the acid-base neutralization solution under the vacuum or near-vacuum environment by using the neutralization chamber 30.
Generally, if the whole neutralization chamber 30 is not in a vacuum environment, the waste gas is simply introduced into the acid-base neutralization solution, and as some liquid is generally carried in the acid gas, a gas-liquid mixed state is formed, and a small bubble is formed in the acid-base neutralization solution, the waste gas and the neutralization solution are not completely contacted, so that the whole neutralization efficiency and neutralization effect are greatly influenced.
The entire apparatus in this application includes an adsorption chamber 20, a neutralization chamber 30, and a blower.
In order to solve the above problems, firstly, an air inlet is arranged at the bottom of the side wall of the adsorption chamber 20, and an air outlet is arranged at the top of the side wall; a plurality of dry type adsorption particle layers are arranged between the air inlet and the air outlet; adsorbent particles are placed in the adsorption layer; and air holes are formed in the top and bottom interlayer plates of each adsorption layer and used for allowing waste gas to flow in and out.

An acid-base neutralizing liquid is disposed in the neutralizing chamber 30 for neutralizing the exhaust gas. The concentration of the acid-base neutralization solution is selected according to actual requirements. Generally, dry adsorption is mainly used, but dry adsorption cannot be completely absorbed, so that the waste gas is completely treated by a neutralizing liquid, and the standard air is discharged.
The gas outlet of the adsorption chamber 20 is connected with a conduit 31, and the bottom of the conduit 31 is inserted to be close to the bottom of the neutralization chamber 30 so as to enable the whole waste gas to be neutralized in the acid-base neutralization solution for a longer time as much as possible. A fan air passage is provided at the top edge of the neutralization chamber 30. In order to ensure that the whole neutralization chamber 30 is in a vacuum state or a nearly vacuum state, the suction rate of the fan is greater than the air inlet rate of the conduit 31 in the neutralization chamber 30, and once the suction rate is reduced to be lower than the air inlet rate, the acid-base neutralization liquid is likely to be sucked up. The air suction rate is large, and is preferably larger than the air inlet rate generally, so that the vacuum of the whole neutralizing chamber 30 is ensured, the inlet waste gas can be forced to flow in and out of the acid-base neutralizing liquid, the waste gas cannot stay in the acid-base neutralizing liquid in a bubble form, and the neutralizing efficiency is improved.
The air inlet and the gas outlet of adsorbing chamber 20, the air inlet and the gas outlet of fan all are provided with the wind pressure sensor, and all wind pressure sensors are connected with the control end, and as the control of wind pressure, this piece belongs to prior art, does not give unnecessary details.
As a specific embodiment, the side wall of the neutralization chamber 30 is provided with a liquid level indicator alarm at a low position to prevent too little acid-base neutralization liquid. The specific position is placed according to the actual need.
As a specific example, each adsorbent layer is replaced within the adsorption chamber 20 using a drawer pull.
