Multiphase Cyclone Separation Units and Cyclone Separators

Abstract

The invention discloses a multiphase cyclone separation unit and a cyclone separator. The separation unit comprises an inner tube (1) and an outer tube (2), the outer tube (2) sleeves coaxially the inner tube (1) and is radially separated from the inner tube (1), the bottom end of the inner tube is an air inlet (J), the bottom end of the outer tube is a gas outlet (C), the top ends of the inner and outer tubes are both closed ends, the outer circumferential wall of the top end of the inner tube is connected to a plurality of cyclone generating tubes (3) arranged at intervals along a circumferential direction, the rising flow in the inner tube forms a rotational flow at the outlet end of the cyclone generating tube, the rotational flow rotates downward along the inner wall surface of the outer tube and is rotationally discharged from a gas outlet at the bottom and separation units can be installed on a tower plate (6) side by side to form the cyclone separator. The multiphase cyclone separation unit utilizes an inner-outer casing pipe mode, utilizes easily available raw materials and has a simple structure. The entrainment and particles are thrown to the inner wall of the outer tubeunder a centrifugal force, then rotatingly fall off along the inner wall of the outer tube under action of gravity and then are collected. The purified gas flows out of the gas outlet at the bottom end of the outer tube and then rises under the action of inertia so that the solid-liquid separation effects are good, pressure drop is small and energy consumption is small.

Description

technical field [0001] The invention relates to a multi-phase separation device, in particular to a novel cyclone separation device. Background technique [0002] In some reactions in the chemical industry, the production or treatment of gas-liquid-solid separation after the reaction, natural gas purification process, etc. are faced with the problem of how to quickly and efficiently separate the reaction tail gas from the liquid products and impurities. The characteristics are: A small amount of mist is carried in the large-flow gas, and a small amount of solid fine particles are entrained in the liquid. The small size of the mist and particles makes it difficult to capture the liquid and solid phases, which increases the difficulty of separation. It is difficult to fully utilize the existing conventional separation equipment. The mist and solid particles in the reaction tail gas can be effectively removed, which will inevitably affect the downstream operation. In addition,...

Problems solved by technology

[0005] As a professional equipment, this combined gas-liquid separator has good gas-liquid separation effect, but its disadvantages are also obvious. Liquid separation effect, and the equipment structure is complicated, expensive, and takes up a lot of space, especially the pressure drop at the inlet and outlet ports, resulting in huge energy consumption
