In the middle of the upper end of the equipment main body, an air outlet is penetrated and opened. Inside the air outlet, an exhaust fan is fixedly installed. Inside the equipment main body, a filter element, an electrostatic dust removal area, and a stainless steel wire mesh are fixedly installed in sequence from top to bottom. On the front side of the lower end of the equipment main body, an air inlet is opened. In front of the air inlet, a collection hood for collecting dust-containing oil mist gas is fixedly installed. On the rear side of the middle part of the equipment main body, a pair of opening magnetic adsorption sealing doors are hingedly installed;

[0007] A liquid accumulation tank is fitted and movably connected to the inner bottom of the equipment main body. On the rear side of the lower end of the equipment main body, a maintenance opening is opened. A sealing panel is fixedly installed at the rear end of the liquid accumulation tank.

[0013] Preferably, the drain pipe penetrates outward through the sealing panel, and a switch valve is fixedly installed at the opening of the rear end of the drain pipe.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. When the dust-containing oil mist gas enters the bottom inside the equipment main body, due to the increase in the flow cross-section and the decrease in the air flow velocity, large-particle oil mist and soot will fall into the liquid accumulation tank under the action of their own gravity. The gas containing smaller oil mist will follow the air flow into the stainless steel wire mesh. After the rectification, collision, and condensation processes of the stainless steel wire mesh, the oil mist and soot will be blocked at the upper end of the stainless steel wire mesh and gradually condense into droplets, which will fall into the liquid accumulation tank under the action of gravity. At the same time, the gas containing fine soot and oil mist will continue to follow the air flow into the electrostatic dust removal area. When the gas containing fine soot and oil mist enters the electrostatic dust removal area, under the action of the DC high-voltage electric field generated by the high-voltage power supply inside the electrostatic dust removal area, the gas is ionized to generate a large number of free electrons and positive ions. When the oil-containing gas passes through the space with a large number of ions and electrons, the ions and electrons will attach to the soot. The soot attached with negative ions and electrons is negatively charged, and the soot attached with positive ions and electrons is positively charged, so that the charged soot is adsorbed on the upper ends of the cathode plate and anode plate inside the electrostatic dust removal area, separating the fine soot and oil mist in the gas. Finally, the gas is purified and filtered through the filter element, and the purified and filtered gas is discharged outward through the exhaust fan, thus realizing the function of multi-stage purification of the dust-containing oil mist gas;

[0016] 2. The present utility model also opens the magnetic adsorption sealing door. When the magnetic adsorption sealing door is opened, the rear side of the equipment main body can be opened for maintenance and cleaning of the inside of the equipment main body. At the same time, by controlling the opening of the driving motor, when the driving motor is turned on, it will drive the first sprocket to rotate. When the first sprocket rotates, it will drive the second sprocket to rotate through the chain. When the second sprocket rotates, it will drive the transmission screw to rotate. When the transmission screw rotates, the U-shaped moving seat will move linearly backward along the inner wall of the limit straight chute due to the force generated by the threaded connection between the front outer curved surface of the transmission screw. When the U-shaped moving seat moves linearly backward, it will drive the liquid accumulation tank to move linearly backward along the inner wall of the maintenance opening out of the bottom inside the equipment main body. When the liquid accumulation tank moves out of the bottom inside the equipment main body, it is convenient to maintain and clean the oil stains attached to the inside of the liquid accumulation tank, thus realizing the function of multi-stage purification of the dust-containing oil mist gas and facilitating the maintenance and cleaning of the inside of the equipment main body at the same time.

A sealing panel 13 is fixedly installed at the rear end of the accumulation tank 11, and the sealing panel 13 is fittingly and movably connected to the inner wall of the maintenance opening 12, so that the maintenance opening 12 is fittingly sealed by the sealing panel 13.

[0025] Working principle: During use, this utility model collects the dust-containing oil mist gas through the collection hood 9. When the collection hood 9 collects the dust-containing oil mist gas, the exhaust fan 4 is controlled to start. When the exhaust fan 4 starts, an upward airflow is generated inside the equipment main body 2. When an upward airflow is generated inside the equipment main body 2, the dust-containing oil mist gas will enter the bottom inside the equipment main body 2 through the collection hood 9 and the air inlet 8. When the dust-containing oil mist gas enters the bottom inside the equipment main body 2, due to the increase in the flow cross-section and the decrease in the air velocity, large-particle oil mist and soot will fall into the liquid accumulation tank 11 under the action of their own gravity. The gas containing smaller oil mist will follow the airflow into the stainless steel wire mesh 7. After the rectification, collision, and condensation processes of the stainless steel wire mesh 7, the oil mist and soot will be blocked at the upper end of the stainless steel wire mesh 7 and gradually condense into droplets and fall into the liquid accumulation tank 11 under the action of gravity. At the same time, the gas containing fine soot and oil mist will continue to follow the airflow into the electrostatic precipitation area 6. When the gas containing fine soot and oil mist enters the electrostatic precipitation area 6, under the action of the DC high-voltage electric field generated by the high-voltage power supply inside the electrostatic precipitation area 6, the gas is ionized to generate a large number of free electrons and positive ions. When the oil-containing gas passes through the space with a large number of ions and electrons, the ions and electrons will attach to the soot. The soot attached with negative ions and electrons is negatively charged, and the soot attached with positive ions and electrons is positively charged, so that the charged soot is adsorbed on the upper ends of the cathode plate and anode plate inside the electrostatic precipitation area 6, separating the fine soot and oil mist in the gas. Finally, the gas is purified and filtered through the filter element 5, and the purified and filtered gas is discharged outward through the exhaust fan 4, thus realizing the multiple purification of the dust-containing oil mist gas;

[0026] When it is necessary to perform maintenance and cleaning inside the equipment main body 2, the double-opening magnetic adsorption door 10 is opened. When the double-opening magnetic adsorption door 10 is opened, the rear side of the equipment main body 2 can be opened to perform maintenance and cleaning inside the equipment main body 2. At the same time, the driving motor 15 is controlled to start. When the driving motor 15 starts, it will drive the first sprocket 16 to rotate. When the first sprocket 16 rotates, it will drive the second sprocket 17 to rotate through the chain. When the second sprocket 17 rotates, it will drive the transmission screw 18 to rotate. When the transmission screw 18 rotates, the U-shaped moving seat 19 will move linearly backward along the inner wall of the limit straight chute 14 due to the acting force generated by the threaded connection between the front outer curved surface of the transmission screw 18. When the U-shaped moving seat 19 moves linearly backward, it will drive the liquid accumulation tank 11 to move linearly backward out of the bottom inside the equipment main body 2 along the inner wall of the maintenance opening 12. When the liquid accumulation tank 11 moves out of the bottom inside the equipment main body 2, it is convenient to perform maintenance and cleaning on the oil stains attached inside the liquid accumulation tank 11, thus realizing the multiple purification of the dust-containing oil mist gas and at the same time facilitating the maintenance and cleaning inside the equipment main body 2.
