The high-pressure fan 1 extracts the waste gas produced by the fermentation of the biochemical chamber, and enters the aeration device 7 through the intake pipe 5. The aeration device 7 continuously generates bubbles to fully contact the gas with the liquid, so that most of the harmful gases dissolved in water such as ammonia are absorbed. , and eliminates unpleasant odors. The exhaust gas produced by the biochemical fermentation chamber contains a large amount of water vapor and heat generated by fermentation. As the exhaust gas continues to enter the purifier in the box, the liquid concentration of the purifier gradually increases. At this time, the purifier in the box needs to be replaced, because the exhaust gas Water vapor can gradually increase the temperature and liquid level of the liquid, so the concentration of the liquid solution can be reflected by monitoring the temperature and liquid level of the purifying agent in the tank: the liquid level of the purifying agent increases to the position of the liquid level sensor 2, and the liquid level sensor 2 will The signal is sent to the controller, and the controller controls the drain pipe 8 to discharge the purifying agent, and the water inlet pipe 9 is filled with new water to a suitable position; or when the temperature sensor 4 monitors that the temperature of the liquid exceeds a certain value, the signal is sent to the controller to control the discharge. Waste liquid, add new liquid. The gas enters the secondary purification device through the aeration device 7, and a part of water will splash into it, but it can flow back through the primary and secondary connecting pipes. Due to the reduction of evaporation and splashing liquid, after the liquid level is lower than a certain position, the liquid level sensor 3 and the liquid level sensor 5 can transmit signals to the controller, and the controller controls the water inlet pipe 9 to add cleaning agent. The secondary gas purification device further absorbs the residual harmful gas. The device can be equipped with an activated carbon adsorption layer, a uv photolysis purification (ozone oxidation) device, a plasma deodorization purification device, etc. The liquid in the primary gas purification device can be water, a liquid added with a chemical agent that can react with the exhaust gas, or a liquid of various deodorants, and other liquids that absorb exhaust gas and eliminate odors.
