Abstract

The invention provides high-temperature gas-solid mixed phase separation equipment which comprises a vortex-shaped vortex flow channel, a gas-solid phase separation device and a gas-solid phase separation device, and the vortex flow channel comprises at least one circle of side wall; the first water spraying opening is formed in the inner side face of the first side wall and extends from one end of the vortex flow channel to the other end of the vortex flow channel in the longitudinal direction; the first water spraying opening communicates with a water pump and sprays water under the action of the water pump, so that the inner side face of each side wall in the at least one circle of side walls is covered with a water film; the outlet flow channel is arranged at the tail end of the first flow channel in the at least one cylindrical flow channel and is communicated with the first flow channel and the gas-liquid separation device; the gas-liquid separation device comprises an exhaust device and a drainage device; wherein a high-temperature gas-solid mixed phase containing molten particles is jetted to the inner side surface of the first side wall through the first opening and enters the at least one cylindrical runner; and the high-temperature gas-solid mixed phase containing the molten particles in the at least one cylindrical runner is driven by the exhaust device to flow in the at least one cylindrical runner.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of gas-solid separation, in particular to a high-temperature gas-solid mixed phase separation equipment. Background technique [0002] In powder combustion, powder metallurgy and other industries, it is necessary to separate and cool the high-temperature gas-solid mixed phase containing molten particles, for example: in the powder combustion industry, the high-temperature flue gas discharged from the combustion furnace using coal powder as fuel , is a high-temperature gas-solid mixed phase containing molten particles, if discharged directly into the atmosphere, it will pollute the environment. In the powder metallurgy industry, the production of amorphous metal powder requires rapid cooling of the molten particles in the gas flow. Since the gas cooling rate does not meet this requirement, the high-temperature gas-solid mixed phase containing molten particles needs to be separated in...

Problems solved by technology

Metal materials commonly used in separation equipment will have problems such as metal oxidation and high-temperature plastic deformation under such high-temperature long-term action, and after the high-temperature gas-solid mixed phase containing molten particles enters the commonly used gas-solid separation equipment, the molten particles will be adsorbed, sticky, etc. Sticking to the inner wall of the separation equipment, with the cooling and solidification of the molten particles, the particles and the inner wall of the equipment are integrated, and the solidified particles and the molten particles are mutually adsorbed, sticky, cooled and solidified, and finally on the inner wall of the equipment Large accumulations are formed on the surface, destroying and blocking the internal structure of the separation equipment, resulting in failure of the separation equipment
