This case provides an oil-gas separator housing, including a base 1 and a housing body 2 erected on the base. The top of the housing body 2 is provided with a plurality of separator mounting holes 21 for installing the oil-gas separator. The housing body 2 An exhaust passage 3 communicating with the installation hole of the separator is opened inside the housing body 2, and an air inlet 22 communicating with the exhaust passage is provided on the side wall of the housing body 2. The oil-gas separator housing is surrounded by the housing main body 2 and the base 1 to form an exhaust channel 3 for guiding oil and gas. The top of the housing main body 2 is provided with a plurality of separator mounting holes 21, and each separator mounting hole 21 can be The oil-gas separator is independently installed and supported, and the side wall of the housing main body 2 is provided with an air inlet 22. When the oil and gas are separated, the oil and gas are input into the exhaust channel 3 through the air inlet 22, and the inner space of the housing main body 2 is large. It can reduce the speed and stabilize the pressure of oil and gas. The oil and gas with stable air flow enter each oil and gas separator respectively through the exhaust channel. Multiple oil and gas separators can simultaneously separate oil and gas. The integrated support of each oil-gas separator is fixed, which reduces the space occupation and meets the oil-gas separation function. The oil-gas separation pipeline can be arranged by setting a unified pipeline, which simplifies the pipeline structure, solves the problem of interference between the pipeline and parts, and improves the appearance. .

In a specific embodiment of the present case, the exhaust passage 3 includes a first passage 31 communicating with the air inlet 22, and a second passage 32 stacked above the first passage 31 and communicating with the separator installation hole 21; The bottom of the main body 2 along the air intake direction of the air inlet 22 defines an air guide port 4 communicating with the first channel 31 and the second channel 32 . The oil and gas are connected to the air inlet 22 of the oil-gas separator housing through the oil-gas pipeline. Since the space inside the housing body 2 becomes larger, the oil and gas are separated by multiple oil-gas separators, and the concentration of oil and gas near the air inlet 22 will be high and far away The low oil and gas concentration at the air inlet 22 corresponds to multiple oil and gas separators, and the utilization rate of the oil and gas separators near the air inlet is high, which affects the uniformity of oil and gas separation.

The exhaust channel 3 in the housing main body 2 is provided with a stacked first channel 31 and a second channel 32, the two communicate through the air guide port 4 at the bottom of the housing main body 2 away from the air inlet 22, and the first channel 31 is filled with oil and gas After that, it goes up to the second channel 32 through the air guide port 4, so that the oil and gas in the second channel 32 are uniform, and each oil-gas separator can achieve the maximum filtering effect and improve the filtering effect.
