Oil-gas purification device and method for deep sea confined space

Abstract

The invention discloses an oil-gas purification device for deep sea confined space. The oil-gas purification device comprises a condensation nucleus generating device, an oil-gas pumping device, an oil-gas condensation device, a centrifugal separation device, an oil collecting tank and a filtering purification device, wherein the condensation nucleus generating device comprises a first water inletpipe, a first heater, an atomizer, an air compressor and a dryer; the oil-gas pumping device comprises an oil inlet pipe, a second heater and a fan; the oil-gas condensation device includes a secondwater inlet pipe, a tubular condenser and a water outlet pipe; the oil collecting tank is arranged under a shell body; the centrifugal separation device includes a driving motor and a centrifugal impeller; and the inlets of the filtering purification device are connected with the outlets on the side wall of the shell body, and the outlets of the filtering purification device are correspondingly connected with air outlet pipes and the inlets of the air compressor. According to the oil-gas purification device for the deep sea confined space, the oil-gas purification efficiency can be improved, the air quality of the deep sea confined space is better improved, energy is saved, noise is reduced, the service life of a system is prolonged, and the use cost of the system is lowered.

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
