Problems solved by technology
At present, the common gas-liquid separation devices in the market are mainly in the form of gravity sedimentation, centrifugal separation or baffle separation. During the use of repair projects, there are common problems such as bulky equipment, low efficiency of gas-liquid separation, large operating resistance, and damage to gas-liquid. Compared with the poor tolerance of load changes, the oil phase and water phase in the liquid phase need to be separated separately, easy to clog and many other problems, it is necessary to provide a new technical solution to solve the above problems

The invention discloses a gas-liquid separation method for in-situ remediation of polluted soil and underground water. The gas-liquid separation method is carried out through a gas-liquid separation device. The device comprises a box body, a fluid inlet, a water outlet, a gas exhaust port, a demister, a liquid level meter connector, an oil outlet, an emptying port, an upper baffle plate, a lower baffle plate and a supporting piece; the box body is a cuboid; the fluid inlet is formed in the upper part of the front end surface of the box body, the water outlet is formed in the lower part of the same end surface, and the oil outlet is formed in the lower part of the rear end surface of the box body; and the gas exhaust port, the demister and the liquid leve meter connector are arranged at the top end of the box body, the emptying port is arranged on the side face of the box body, the upper baffle is arranged on the upper portion in the box body, the lower baffle is arranged on the lower portion in the box body, and the supporting piece is arranged on the bottom face of the box body. The invention provides the gas-liquid separation method which is simple in device structure, good in stability, high in gas-liquid separation efficiency, has an oil-water separation function, and can be universally and effectively suitable for the in-situ remediation construction process of the soil and underground water polluted land parcels.
Description
technical field [0001] The invention relates to a gas-liquid separation method used in the technical field of soil and groundwater remediation of polluted sites, in particular to a method for in-situ multi-phase extraction and in-situ thermal desorption remediation of polluted soil and / or groundwater. Surface gas-liquid separation methods required for in-situ remediation technology. Background technique [0002] With the advancement of urbanization and the adjustment of industrial structure, industrial enterprises such as pesticides and chemicals in large and medium-sized cities have been gradually shut down or moved out of urban areas. At the same time, a large number of lands polluted by organic matter have been left behind to carry out soil and groundwater restoration work. Multiphase extraction technology is an environmentally friendly in-situ remediation technology for organic pollution of soil and groundwater. It has the advantages of simple and reliable system, can ha...
