Sealed gas intake device for storage tank

Abstract

The invention discloses a sealed gas intake device for a storage tank, and mainly relates to the field of petroleum equipment. The sealed gas intake device comprises a framework, a gas exhaust device,a control cabinet and a connecting structure, wherein the framework is a three-dimensional truss structure formed by welding profile steel; the gas exhaust device is fixedly arranged inside the framework; the control cabinet is fixed to one side of the framework for realizing control on electrical equipment; the connecting structure is used for quickly realizing connection, in the vertical direction, of two devices; the connecting structure comprises a shaft center body and a fixed barrel, the shaft center body is fixedly arranged on the top of the framework, the fixed barrel is fixedly arranged on the bottom of the framework, the shaft center body and the fixed barrel correspond in position in the vertical direction, the outer diameter of the shaft center body is matched with the inner diameter of the fixed barrel, and relative through holes are formed in the side surface of the shaft center body and the side surface of the fixed barrel, so that the shaft center body and the fixed barrel are fixedly connected through pinned connecting and matching. The sealed gas intake device has the beneficial effect that a novel gas exhaust device can be quickly additionally arranged on the gas exhaust device in the vertical direction.

Description

technical field [0001] The invention relates to the field of petroleum equipment, in particular to a closed gas collection device for a storage tank. Background technique [0002] Crude oil will lose part of its light components due to evaporation during the process of gathering, transportation, storage and transportation, which will not only waste natural gas resources, but also cause pollution to the atmospheric environment. If these components are recovered, it will not only increase the production of natural gas in the oil field, but also reduce the waste of energy; prevent the pollution of the atmosphere caused by the volatilized natural gas on the top of the oil tank, and protect the environment; at the same time, it reduces the fire risk factors in the oil tank area and increases ensure the safety of oil and gas gathering and transportation. In the process of oil field exploitation, the production volume is generally small from the beginning to the subsequent product...

Problems solved by technology

If a very redundant air extraction device is used at the beginning, the device will waste energy. If a smaller device is used to add equipment later, there will be a lot of open space in the early stage, which will also cause a waste of space.
