Description

Screen mesh type gas-liquid separation device Technical Field The utility model relates to chemical equipment, in particular to a screen type gas-liquid separation device. Background In industrial production, the separation of a gas-liquid mixture is a common and important process, and is widely applied to the fields of chemical industry, petroleum, environmental protection, food processing, pharmacy and the like. The purpose of the gas-liquid separation is to effectively separate the gas and the liquid so as to meet the requirements of the subsequent process or the emission standard. The traditional gas-liquid separation method mainly comprises gravity separation, centrifugal separation, filtration separation, membrane separation and the like. Gravity separation utilizes the density difference between gas and liquid to achieve natural separation, but is inefficient, especially with small droplets or high flow velocity mixtures. Centrifugal separation is accelerated by centrifugal force generated by high-speed rotation, and efficiency is high, but equipment is complex, energy consumption is high, and maintenance cost is high. The liquid drops are intercepted by the filter screen through the filter separation, but the filter screen is easy to be blocked and needs to be replaced frequently. The membrane separation technology is efficient and accurate, but has high cost, easy pollution and limited application range. In addition, the traditional gas-liquid separation device generally has the problems of complex structure, large occupied area, low separation efficiency, difficult maintenance and the like. For example, the multistage separation structure improves the efficiency, but the equipment is huge, and the complex mechanical structure is efficient, but the cost is high, the energy consumption is high and the equipment is easy to break down. Therefore, a gas-liquid separation device with simple structure, high separation efficiency, convenient maintenance and wide application range is needed.
