A device and method for purifying oil and gas in a deep-sea confined space

Abstract

The invention discloses an oil gas purification device used in a deep-sea confined space, which comprises a condensation nucleation generating device, an oil and gas suction device, an oil gas condensing device, a centrifugal separation device, an oil collection tank and a filtering and purification device. The condensation nucleation generating device includes a first Water pipe, first heater, atomizer, air compressor and dryer; oil and gas suction device includes oil and gas inlet pipe, second heater and fan; oil and gas condensing device includes second water inlet pipe, shell and tube condenser and outlet water pipe; the oil collection tank is arranged under the housing; the centrifugal separation device includes a driving motor and a centrifugal impeller; the inlet of the filtering and purifying device is connected to the outlet on the side wall of the housing, and the outlets of the filtering and purifying device are respectively connected to Air pipe and air compressor inlet. The invention can improve the oil and gas purification efficiency, better improve the air quality in the deep-sea confined space, save energy, reduce noise, increase the service life of the system, and reduce the use cost of the system.

Description

technical field [0001] The invention belongs to the technical field of oil and gas purification, and more particularly relates to an oil and gas purification device and method for deep-sea confined spaces. Background technique [0002] With the continuous development of marine resources and the emphasis on ocean sovereignty, various manned deep-sea confined space systems have developed rapidly, such as deep-sea space stations, submarines, manned submersibles, etc. In deep-sea confined space systems, there are many mechanical equipment Lubricating oil and hydraulic oil, during operation, mechanical equipment will continue to generate oil and gas and emit it into the confined space, and the atmosphere in the space is completely closed, with the accumulation of time, it will seriously affect the working environment and environment in the confined space. Personnel are physically and mentally healthy, so corresponding oil and gas purification devices are needed to purify the oil ...

AI Technical Summary

Problems solved by technology

[0003] Traditional oil and gas purification devices mainly use two methods of centrifugal separation and filtration purification after condensation to purify oil and gas, but condensation requires energy consumption for compression and refrigeration, and the particle size distribution of the condensed oil mist is wide, which is not conducive to subsequent filtration and purification materials. selection and maintenance
