Flue gas purification system for aluminum purification furnace

Abstract

The invention provides a flue gas purification system for an aluminum purification furnace, and belongs to the technical field of application of aluminum processing equipment. The flue gas purification system comprises a shell, a gas inlet, a precipitation cavity, reaction cavities and a cooling cavity, wherein the gas inlet is fixedly formed in the front end of the shell; a filter screen is fixedly arranged in the middle of the gas inlet; the precipitation cavity is fixedly connected to the inner side of the gas inlet; a water column is rotationally arranged in the middle inside the precipitation cavity; colloidal bars are fixedly arranged on two sides of the water column; the precipitation cavity is fixedly connected with the reaction cavities through conveying pipes; the reaction cavities are fixedly connected with the cooling cavity through the conveying pipes; and collecting balls are fixedly arranged in the cooling cavity. Through the arrangement of the filter screen at the air inlet, large-particle substances in flue gas can be filtered and adsorbed; through the arrangement of the precipitation cavity, water is sprayed in the precipitation cavity through the water column, so that the small-particle substances in the flue gas are subjected to water vapor condensation; through the arrangement of the reaction cavities, substances in the flue gas are subjected to a chemical reaction to form precipitates and the like; and finally, the cooling cavity is arranged to cool and precipitate the reacted flue gas.

Description

technical field [0001] The invention relates to the technical field of aluminum processing equipment, and more specifically, to a flue gas purification system for an aluminum purification furnace. Background technique [0002] In the process of aluminum processing, in the purification process, the flue gas produced by purification is generally discharged directly or after a little simple physical treatment. Since the flue gas produced by aluminum purification contains some toxic and harmful substances, it is directly discharged or treated. If it is not thorough, it will pollute the air, and then affect people's normal life, which is not conducive to the protection of the environment. Contents of the invention [0003] The present invention aims to solve the problem that the traditional flue gas from aluminum purification is directly discharged into the air or discharged after a little simple physical treatment, so that the toxic and harmful substances in the flue gas enter...

[0002] In the process of aluminum processing, in the purification process, the flue gas produced by purification is generally discharged directly or after a little simple physical treatment. Since the flue gas produced by aluminum purification contains some toxic and harmful substances, it is directly discharged or treated. If it is not thorough, it will pollute the air, which will affect the normal life of people and is not conducive to the protection of the environment.
