Novel cyclone separator

Abstract

The invention relates to a novel cyclone separator which comprises the following parts of an air inlet pipe (2) having a circular cross section and radially distributed, a cylinder barrel (3), and an exhaust pipe (4), wherein the side surface of the upper part of the cylinder barrel (3) is communicated with the air inlet pipe (2), an ellipsoidal head (1) is installed at the top part of the cylinder barrel (3), the bottom of the cylinder barrel (3) is communicated with a conical barrel (7), the exhaust pipe (4) is located in the cylinder barrel (3) and penetrates through the ellipsoidal head (1), and an erosion prevention guide baffle (5) and a multi-layer spiral guide vane (6) are arranged on the outer side of the exhaust pipe (4). Compared with the prior art, the novel cyclone separator is simple in structure, reasonable in construction, and reliable in operation, has excellent structural strength and separation performance, is particularly suitable for long-term operation at high temperature and high pressure, and is applicable to dust separation and particle recycle for high-temperature and high-pressure gases in the processes of petroleum, chemical engineering, clean coal utilization and the like.

Description

technical field [0001] The invention relates to an industrial gas-solid separation device, in particular to a high-temperature and high-pressure coal gas dedusting cyclone separator. Background technique [0002] Integrated gasification combined cycle (IGCC for short) power generation is an efficient and clean technology of using coal to generate electricity, and it is a hot spot in the energy and power circles of the world today. Although the gas used for IGCC power generation does not require high calorific value, it has a very high requirement for gas purification. Therefore, the dust removal and purification of high-temperature and high-pressure crude gas is an indispensable and important part of the IGCC system. Because of its simple structure, convenient operation and maintenance, and high separation efficiency, the cyclone separator can be used as the first choice for the primary pre-dust removal equipment for crude gas purification. The top of the traditional cyclon...

AI Technical Summary

Problems solved by technology

The top of the traditional cyclone separator is generally a flat roof, and the intake pipe structure is a rectangular tangential intake structure, which has many right-angle welds, which seriously affects the separator to withstand high pressure and temperature loads, so the conventional The gas operating pressure of the cyclone separator is generally less than 0.5MPa, while the pressure of the crude gas produced by the gasification of coal in the gasifier in the IGCC power generation system is relatively high, generally 2-4MPa
