Primary filter system

Abstract

The invention discloses a primary filter system. The primary filter system comprises a sealed box body internally provided with a cavity, wherein a water inlet tube and a water outlet tube are respectively arranged on symmetrical side walls of the box body, one end of the water inlet tube and one end of the water outlet tube are communicated with the cavity, the water inlet tube is arranged above the water outlet tube, a clapboard is arranged in the cavity and is arranged between the water inlet tube and the water outlet tube, the top end of the clapboard and the top end of the cavity are in seamless connection, the side wall of the clapboard and the side wall of the cavity are in seamless connection, a clearance exists between the bottom end of the cavity and the bottom end of the clapboard, and a filter device is arranged in the cavity, is fixed with the wall surface of the cavity, is arranged right below the end head of the water inlet tube in the cavity, and is arranged between the clapboard and the water inlet tube. The filter system can filter the petroleum primarily by using the physical property of petroleum floating on water surface, thus not causing secondary pollution to the water body, and solving the problem of secondary pollution caused by existing method of treating petroleum contamination with chemical reagents.

Description

technical field [0001] The invention relates to a system, in particular to a primary filtration system, which belongs to the field of primary oil treatment. Background technique [0002] Petroleum, also known as crude oil, is a viscous, dark brown liquid. There are oil reserves in parts of the upper crust. The main component is a mixture of various alkanes, naphthenes and aromatic hydrocarbons. It is formed by the long-term evolution of organisms in ancient oceans or lakes, and it belongs to fossil fuels. Petroleum is mainly used as fuel oil and gasoline, and is also a raw material for many chemical industry products such as solutions, fertilizers, pesticides and plastics. The nature of petroleum varies with the place of origin, the density is 0.8-1.0g / cm3, the viscosity range is very wide, the freezing point varies greatly (30-60 degrees Celsius), the boiling point ranges from room temperature to above 500 degrees Celsius, and is soluble in various organic solvents. Ins...
