The top of the box 9 is open and connected to the oil removal tank 1. The junction box 9 includes four inclined plates 9.1 and a bottom plate 9.2 connected to the four inclined plates 9.1. Two adjacent inclined plates 9.1 are fixedly connected, and the bottom plate 9.2 is connected to the lower oil pipe 7. The oil removal tank 1 and the oil storage tank 2 are both provided with inspection openings 10, and an inspection door 11 is fixed to the inspection openings 10 by bolts. The inspection openings 10 include a first inspection opening 10.1 provided at the oil removal tank 1 and a second inspection opening 10.2 provided at the oil storage tank 2, and the number of the first inspection openings 10.1 is multiple. A support frame 12 is connected to the bottom of the oil removal tank 1, and the oil storage tank 2 is fixedly installed on the support frame 12. The support frame 12 includes four support legs 12.1, and a base 13 is connected to the bottom of each support leg 12.1, and the base 13 can be sleeved on the outside of the support leg 12.1 and the two are welded and fixed.

[0046] Working principle: The waste gas degreasing device of the present application takes in air from the air inlet, passes through the degreasing channel formed by three staggered partitions, and then exhausts air from the air outlet. By setting smaller diameters of the air inlet and the air outlet, the flow rate of the waste gas through the tank body is accelerated, and the waste gas hits the partition, leaving the liquid and letting the grease hang on the partition. The three-layer partition is set to increase the stroke of the gas through the tank body, and the degreasing is more thorough. Three first inspection ports are set, and the three first inspection ports are respectively set at the three turns of the degreasing channel to ensure that the space at each turn can be entered for inspection and cleaning. The space at the turn is large, which is convenient for personnel to enter and is also more convenient for cleaning;

[0047] The grease stays on the baffle, and gravity causes it to flow downward. The inclined plate of the junction box below is set steeply to reduce the gentle path and make the grease slide down quickly. A precise first valve is used to prevent leakage and control the grease to slide down. Here, since the junction box is connected to the oil removal tank and the baffle does not extend into the junction box, part of the airflow will pass through the junction box, affecting the oil removal effect. However, since the exhaust gas is hot gas, the hot gas will float upward, and the junction box is small in size, the airflow passing through the junction box is small, and this part of the gas will also pass through the first and third baffles, so the effect on the exhaust gas oil removal effect will not be great.

[0048] Grease flows into the oil storage tank below and can flow out through the oil outlet. A precise second valve is set at the oil outlet for control, and a water inlet is reserved. A third valve is equipped. The third valve is a manual ball valve. The water pipe is connected for easy cleaning. An inspection door is set to facilitate personnel to enter and clean. A lifting lug is set on the top to facilitate crane installation. The base at the bottom is fixed to the installation location with expansion screws, which is stable and reliable, and adopts an adjustable structure. The base and the support frame are not welded or spot welded when shipped, and are fixed to the ground with expansion bolts. According to the actual situation of the construction site, the extension amount of the support leg in the base is adjusted. After the air inlet and outlet are fully matched with the front and rear equipment, the connection between the base and the support leg is fully welded, so as to achieve the effect of adjustable height of the support frame.

[0049] Although the present invention has been illustrated and described with respect to preferred embodiments, it should be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
