Abstract

The invention discloses a gas-solid separator. The gas-solid separator comprises a cone, a cylinder and an air channel, wherein the cone, the cylinder and the air channel are communicated from top to bottom. The gas-solid separator also provides a ventilating duct. The air channel coils on the ventilating duct. An opening of the top of the air channel is an air inlet. The bottom of the cone is provided with a discharging pipe. The top of the ventilating duct is provided with an air outlet. The bottom of the ventilating duct is communicated with the cone and the cylinder. A top surface of the air channel is a spiral cover plate having a downward spiral structure. The gas-solid separator has the advantages of simple structure, high dust collection efficiency, small gas resistance, small system height and diameter, and long service life.

Description

technical field [0001] The invention relates to a gas-solid separation device, in particular to a device for separating gas and solid materials in a system using gas to transport solid materials. Background technique [0002] Gas-solid separation devices are generally used in cement, coal and chemical industries that use gas as a transport method for solid materials, mainly to separate solid materials from the transport medium. In actual use, part of the functions of the gas-solid separation device can be used under high temperature conditions as a component of various systems such as preheating and pre-decomposition systems, chemical reaction systems, activated coal gangue calcination systems, and coal gangue decarbonization systems. [0003] Although there are many forms of gas-solid separation devices, it is always difficult to solve the contradiction between the dust collection efficiency of the separation device and the loss of gas resistance, as well as the limitations...
