Novel multi-section annular oil-gas adsorption tank

Abstract

The invention discloses a novel multi-section annular oil-gas adsorption tank. The novel multi-section annular oil-gas adsorption tank comprises an upper-section columnar adsorption area (1), a lower-section cylindrical adsorption area (2), an outer cylinder (3) and a top cover (4), wherein the outer cylinder (3) is opened upwards, a buffer area (5) is arranged at the bottom of the inner part of the cylinder, the lower-section cylindrical adsorption area (2) and the upper-section columnar adsorption area (1) are mounted on the buffer area (5) coaxially in sequence, the top cover (4) is arranged at the top of the outer cylinder (3), and then a closed tank body is formed; an air inlet (6) is formed in the buffer area (5) of the outer cylinder (3), and an air outlet (7) is formed in the center of the top cover (4); multiple layers of filter screens are arranged between the bottom of the air outlet (7) and the upper-section columnar adsorption area (1). The novel multi-section annular oil-gas adsorption tank is low in cost and high in oil-gas adsorption efficiency, thereby being applied to the oil-gas adsorption tank of a small gas station. A special bed structure is utilized to realize relative control of the activated carbon bed temperature and ensure relatively strong activity of activated carbon, and furthermore, the characteristic of high adsorption efficiency of the activated carbon is utilized to realize high-efficient adsorption of oil and gas.

Description

technical field [0001] This patent relates to the technical field of mechanical structures, in particular to a novel multi-stage annular oil-gas adsorption tank. Background technique [0002] Gasoline, as the fuel oil for most motor vehicles, has to go through at least four loading and unloading links from the refinery to the final use as a fuel for vehicles. Petroleum and its products are a mixture of various hydrocarbons, of which light hydrocarbons are VOCs are highly volatile, so volatile organic compounds (Volatile Organic Compounds, VOCs, commonly known as "oil and gas" in the industry) will inevitably be produced in every link. VOCs are more important than nitrogen oxides (NOx) in enhancing the oxidation of the atmosphere. They are the most important pollutants that form secondary particulate matter and cause severe smog pollution. In recent years, the problem of oil and gas evaporation loss in oil and gas transportation and storage has been very serious, which not o...
