Variable impact oil-gas separator integrated with pressure adjusting function

Abstract

The invention discloses a variable impact oil-gas separator integrated with a pressure adjusting function, and belongs to the technical field of oil-gas separators. The structure comprises a shell, the lower end of the shell is connected with a cyclone separator, a negative pressure area is arranged above the shell, an oil-gas separation body located above the cyclone separator is arranged in the shell, a diaphragm is arranged at the upper end of the oil-gas separation body, a separation hole is formed in the middle of the oil-gas separation body, and an impact column is arranged in the middle of the lower end of the diaphragm. The lower end of the impact column is elastically connected with the bottom end of the separation hole through a spring, the upper end of the separation hole, the diaphragm and the impact column jointly form a spray seam with the adjustable flow intercepting area, the peripheral side of the upper end of the separation hole is a blow-by reserved area communicated with the spray seam, the lower end of the blow-by reserved area is communicated with a blow-by channel, and the lower end of the blow-by channel is communicated with a guide pipe. The oil-gas separation function and the pressure adjusting function are integrated, the integration degree is improved, the structure is simple, and machining is convenient.

Description

technical field [0001] The invention relates to the technical field of oil and gas separators, in particular to a variable impact oil and gas separator with integrated pressure regulation function. Background technique [0002] At present, the oil-gas separator with integrated pressure regulation function is generally divided into two components: a pressure regulation module and an oil-gas separation module. Among them, the cut-off area of ​​the blow-by gas acceleration area in the oil-gas separation module cannot be adjusted. [0003] This shows that the shortcoming of present prior art shows as following two aspects: [0004] 1. The product consists of two modules and requires a large layout space; [0005] 2. Once the cut-off area of ​​the oil-gas separation module is set, it cannot be adjusted, and the separation efficiency changes with the change of the blow-by gas flow rate. The separation efficiency is low under the working condition of small blow-by gas flow rate. ...
