Separation device

Abstract

The invention relates to the technical field of gas-liquid-solid three-phase separation equipment, in particular to a separation device. The separation device is used for purifying the impurity-containing gas and comprises a shell, a first-stage separation mechanism and a second-stage separation mechanism, the first-stage separation mechanism and the second-stage separation mechanism are arranged in the shell, the first-stage separation mechanism can separate the impurity-containing gas to preliminarily remove solid-liquid impurities in the impurity-containing gas so as to obtain primary purified gas, and the second-stage separation mechanism comprises a flow collecting cylinder and a separation piece; and the wide opening side of the flow collecting cylinder is communicated with an exhaust port of the primary separation mechanism for exhausting primary purified gas, the narrow opening side of the flow collecting cylinder is communicated with an exhaust port of the shell, and the separation piece is arranged in the flow collecting cylinder and can be used for carrying out gas-liquid separation treatment on the primary purified gas so as to remove liquid impurities in the primary purified gas to obtain purified gas. According to the separation device, by arranging the first-stage separation mechanism and the second-stage separation mechanism, impurity-containing gas is separated step by step to remove solid-liquid impurities in the impurity-containing gas, so that purified gas is obtained through separation.

Description

technical field [0001] The invention relates to the technical field of gas-liquid-solid three-phase separation equipment, in particular to a separation device. Background technique [0002] The slurry bed reactor is one of the most widely used reactors in the Fischer-Tropsch synthesis process. Compared with the fixed bed reactor, the slurry bed reactor has many advantages such as simple structure, good dispersion effect, good transfer performance, and convenient operation. It can also realize online catalyst replacement, high production capacity, low investment cost, and easy industrial scale-up, which attracts more and more researchers. In recent years, the slurry bed reactor has achieved industrial application in natural gas-to-synthetic oil and natural gas-to-methanol processes, and has great development potential in petrochemical, biochemical and other fields. Generally speaking, the internal structure of a slurry bed reactor includes: heat exchange tubes, gas distribut...
