[0047] Working principle:

[0048] Please refer to Figures 1 to 6 Assemble the device as shown in the figure;

[0049] In operation, this device first installs a dust collector at the exhaust port of the crude oil generator, then connects the air pipe 3 to the exhaust port of the dust collector. Simultaneously, it constructs water and air supply lines for the micro-nano bubble generator 14 to ensure sufficient micro-nano bubble water production. The exhaust gas generated by the crude oil generator, after being filtered by the dust collector to remove a large amount of particulate matter, enters the connecting air pipe 3. The axial flow fan 30 inside the connecting branch pipe 4 introduces high-velocity air, creating negative pressure and continuous exhaust gas output. This causes the exhaust gas, after particulate matter filtration, to quickly enter the filter box 1. After being adsorbed and filtered by the activated carbon adsorbent 5, chitosan adsorbent 6, and polypropylene filter element 7, the exhaust gas enters the protective cone 35 through the flow pipe 10, and then passes through the hemispherical protective mesh head 36. Under the action of the gas generator, the exhaust gas is diffused into the purification cylinder 11 in a hemispherical shape; at the same time, the micro-nano bubble generator 14 sprays atomized micro-nano bubble water through the atomizing nozzle 33. The hot spot effect of the bursting of micro-nano bubbles in the micro-nano bubble water quickly purifies the gaseous pollutants in the exhaust gas of the oil generator. The purified exhaust gas enters the detection gas box 24 through the guide pipe 29. After being detected by the gas concentration detector 27, it is discharged through the exhaust pipe 25. The exhaust gas that meets the emission standards is directly discharged, and the unqualified exhaust gas is re-purified. The exhaust gas generated by the purification inside the purification cylinder 11 falls into the water collection ring trough 38, enters the drain ring pipe 18 through the drain nozzle 39, and then enters the water storage tank 21 through the guide pipe 19, the connecting water pipe 20 and the water inlet positioning pipe 40, waiting for centralized treatment.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
