[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] It is understood that the terms “first” and “second” as used herein may be used to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] like Figures 1 to 4 As shown, an embodiment of the present invention provides a lubricating oil production exhaust gas treatment device, comprising: The treatment box 1 is equipped with a cooling assembly 2, a collection assembly 3, a filter assembly 4, and a spray assembly 5 for treating exhaust gas. The cooling assembly 2 consists of a water chiller unit 21, a variable frequency cooling fan unit 22, an intake pipe 23, and an exhaust pipe 24, and is used to cool the exhaust gas. Collection component 3 is used to collect and discharge condensed liquid. Collection component 3 includes: Collection box 31 is fixedly installed on exhaust pipe 24; A fixed plate 32 is fixedly installed on the collection box 31, and a movable column 33 is slidably fitted on the fixed plate 32. The tension spring 34 has its end face and free end connected to the fixed plate 32 and the collection box 31, respectively. The positioning rod 35 is fixedly installed on the collection box 31, and the movable column 33 is slidably engaged with the positioning rod 35. The fixing pipe 36 is fixedly installed on the collection box 31; The movable plate 37 is fixedly installed on the end face of the movable column 33. The end face and free end of the movable plate 37 are respectively fixedly connected to the buoyancy airbag 38 and the sealing rod 39. Specifically, as a further embodiment of this utility model, the sealing rod 39 is slidably engaged with the fixing tube 36 and the fixing plate 32, and there are two sealing rods 39 and two fixing tubes 36. The end face of the collection box 31 is fixedly installed with a drain pipe 301. In this embodiment of the present invention, in practical application, the intake pipe 23 is connected to the exhaust gas delivery pipe of the lubricating oil production. The exhaust gas is cooled by the cooling component 2. Due to the low temperature, the liquid in the exhaust gas condenses and gathers together and flows into the collection box 31. As the liquid in the collection box 31 increases, the buoyancy force on the buoyancy airbag 38 is greater than the tensile force of the tension spring 34, causing the movable plate 37 to drive the movable column 33 and the sealing rod 39 to move. Since the sealing rod 39 does not contact the fixed pipe 36 and the fixed plate 32 after it moves, the collected liquid is discharged through the fixed pipe 36 and the drain pipe 301.

[0019] like Figures 1 to 4As shown, as a further embodiment of the present utility model, the water chiller unit 21 is fixedly installed on the processing box 1, a temperature sensor is fixedly installed inside the water chiller unit 21, the variable frequency cooling fan unit 22 is installed on one side of the water chiller unit 21, the air inlet pipe 23 is fixedly installed on the top of the water chiller unit 21, and the end face and free end of the exhaust pipe 24 are respectively connected to the water chiller unit 21 and the processing box 1. In this embodiment of the present invention, in actual application, the water chiller unit 21 exchanges heat with the exhaust gas, while the variable frequency cooling fan unit 22 exchanges heat with the water chiller unit 21. At the same time, the speed of the cooling fan is adjusted according to the temperature after heat exchange by the water chiller unit 21 to save energy. The exhaust pipe 24 transports the gas-liquid mixture.

[0020] like Figures 1 to 4 As shown, in a further embodiment of this utility model, the filter component 4 includes: The filter cotton filter plate 41 is snapped onto the processing box 1; Activated carbon filter plate 42 is snapped onto the treatment box 1 on the side near the filter cotton filter plate 41; Molecular sieve filter plate 43 is snapped onto the treatment box 1 on the side where activated carbon filter plate 42 is snapped; In this embodiment of the invention, in practical application, since the water vapor and oil mist inside the exhaust gas are condensed and separated after the exhaust gas is cooled, the multiple filter plates have a better effect on filtration and purification of the exhaust gas.

[0021] By setting up cooling component 2 and collection component 3, the exhaust gas is cooled before treatment to reduce its temperature. At the same time, the condensed liquid is collected, and the frequency of liquid discharge is controlled by the buoyancy of the liquid to further avoid a large amount of exhaust gas leakage when discharging liquid. This also makes the multiple filter plates more effective in purifying the exhaust gas.

[0022] like Figures 1 to 4 As shown, in a further embodiment of this utility model, the spray assembly 5 includes: The liquid storage tank 51 is fixedly installed on the processing tank 1, and a fixed cover is rotatably fitted on the liquid storage tank 51. The delivery pump 52 is fixedly installed on the liquid storage tank 51, and the inlet end of the delivery pump 52 is connected to the liquid storage tank 51 through a pipe. The liquid diversion valve 53 is fixedly installed on the processing tank 1 near the liquid storage tank 51. The liquid diversion valve 53 is connected to the outlet end of the transfer pump 52 through a pipe. The spray pipe 54 is fixedly installed inside the treatment box 1, and the spray pipe 54 is also connected to the liquid diversion valve 53. Spray head 55 is rotatably fitted on spray pipe 54, and there are several spray heads 55; In this embodiment of the present invention, in actual application, after the exhaust gas is filtered by the filter assembly 4, it continues to move through the holes in the treatment box 1. The delivery pump 52 causes the solution in the storage tank 51 to spray the exhaust gas through the liquid diversion valve 53, the spray pipe 54 and the spray head 55, adsorbing the organic gases in the exhaust gas and further improving the efficiency of exhaust gas treatment.

[0023] like Figures 1 to 4 As shown, as a further embodiment of the present utility model, a sealing cover 11 is snapped onto the treatment box 1, and a discharge pipe 12 is also fixedly installed on the treatment box 1. In this embodiment of the invention, in practical application, raising the sealing cover 11 facilitates disassembly and opening of the treatment box 1 to replace the filter assembly 4, while the discharge pipe 12 can discharge the solution after adsorbing organic exhaust gas.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
