Two-stage heat exchange type cyclone separator

Abstract

The invention discloses a two-stage heat exchange type cyclone separator, which has the functions of heat exchange and dust removal at the same time, and a first-stage cyclone separator and a second-stage cyclone separator are selected, wherein fluid directors are arranged in cylindrical sections of the first-stage cyclone separator and the second-stage cyclone separator; the first-stage cyclone separator and the second-stage cyclone separator adopt 360-degree volute type air inlets; and an exhaust port of the first-stage cyclone separator is communicated with an air inlet of the second-stagecyclone separator through a 180-degree volute type pipeline. Heat exchange pipes are coiled on the outer walls of the cylindrical sections of the first-stage cyclone separator and the second-stage cyclone separator, and the rotating direction of the heat exchange pipes is opposite to the airflow direction of the cyclone separators. The cyclone separator not only can improve the separation efficiency and reduce the pressure drop, but also can utilize the waste heat and reduce the energy consumption.

Description

technical field [0001] The invention belongs to the field of dust removal and heat exchange, and in particular relates to a two-stage cyclone separator capable of utilizing waste heat. Background technique [0002] The cyclone separator uses the centrifugal force generated by the high-speed rotating movement of the dust-laden airflow inside to separate the dust particles from the airflow and trap them on the wall of the device, and finally fall into the ash hopper under the action of gravity, so as to achieve the purpose of dust removal Dry gas-solid separation equipment. Due to the advantages of high dust removal efficiency, simple structure, low cost, convenient operation and high reliability, this kind of separation and dust removal equipment is widely used in iron and steel metallurgy, chemical industry, thermal power generation and other industrial fields. In recent years, environmental problems have become increasingly prominent, especially smoke and dust pollution ca...

Problems solved by technology

However, the waste heat carried by the industrial flue gas is directly discharged into the atmosphere after passing through the cyclone separator, which wastes a lot of waste heat of the flue gas.
