Oil storage tank liquid seal mechanical seal double seal integrated environmental protection breathing device

Abstract

An environmental protection breathing device with liquid seal, mechanical seal and double seal for an oil storage tank, including: a shell structure, a breathing valve, a breathing mechanism, a connecting pipe, an air intake mechanism, an exhaust mechanism, a reaction spring and an adsorption filter medium, and the shell structure includes Cylindrical shell, shell seat and shell cover connected with shell bolts, breathing valve set in the middle of shell cover; air intake mechanism includes square air intake pipe welded with air inlet of right-angle connecting pipe, set in square The intake valve has a right-angled trapezoidal sealing cover structure on the upper part of the outer circumference of the intake pipe; the exhaust mechanism includes an exhaust port inserted in the middle of the housing seat, an air inlet in the middle, and a right-angle connecting pipe with a flange at the lower end, which is located at the exhaust port. The upper exhaust valve with the same structure and direction as the intake valve, the exhaust pipe vertically connected to the exhaust valve, and the annular pipe at the bottom of the lower end of the exhaust pipe; The spherical activated carbon inside and the transformer oil at the bottom of the housing. Environmental pollution is prevented and lightweight components are recovered.

Description

technical field [0001] The invention relates to the technical field of oil storage safety, in particular to a liquid-sealed, mechanical-sealed, double-sealed integrated environmental protection breathing device for an oil storage tank. It solves the problems of large investment in double setting of oil storage tank liquid seal and mechanical seal breathing valve, environmental pollution of exhaled gas and non-recovery of light oil. Background technique [0002] At present, the oil storage tanks used in the society, the oil field joint processing station and the oil storage tanks used by the oil pipeline bureau are all equipped with liquid-sealed breathing valves and mechanical breathing valves for the safety of the oil storage tanks and to reduce the volatilization of oil and gas in the oil storage tanks. Oil storage is carried out in a micro-pressure sealed manner, while protecting the safety of the oil storage tank. The liquid-sealed breathing valve does not work normally...

AI Technical Summary

Problems solved by technology

This setting ensures the working safety of the oil storage tank, but the harmful gas such as hydrogen sulfide and light components of the oil are still discharged into the atmosphere during the exhaust process of the mechanical breathing valve, which pollutes the environment and wastes energy, and the setting of the two valves is inconvenient to manage , the investment is still large, so the country will lose a lot of oil and gas resources and processing costs every year
