Dry salt secondary heating incineration system for solid-liquid treatment and use method of dry salt secondary heating incineration system

Abstract

The invention discloses a dry salt secondary heating incineration system for solid-liquid treatment and a use method of the dry salt secondary heating incineration system. The dry salt secondary heating incineration system for solid-liquid treatment comprises an air inlet steel pipe, a mounting block is arranged at the bottom end of the air inlet steel pipe and fixedly connected with a building, and a rotary assembly is arranged on one side of the air inlet steel pipe; a butt joint pipe body is arranged on the side, away from the air inlet steel pipe, of the rotary assembly, a turning steel pipe is arranged below the butt joint pipe body, a thin pipe is arranged on one side of the turning steel pipe, a heating pipe body is arranged at the end of the thin pipe, and a fan is arranged in the center of the air inlet steel pipe and fixedly connected with the inner side wall of the air inlet steel pipe through an extending support; and a connecting flange is arranged at one end opening of the air inlet steel pipe, the diameter of the end opening, connected with the flange, of the other end opening of the air inlet steel pipe is small, and a glass fiber filter screen is arranged at the end opening, with the small opening diameter, of the air inlet steel pipe. The glass fiber filter screen in the end opening of the air inlet steel pipe can remove particle impurities in air.

Description

technical field [0001] The invention relates to the technical field of solid-liquid treatment, in particular to a dry salt secondary heating and incineration system for solid-liquid treatment and a use method thereof. Background technique [0002] Landfill leachate refers to landfill leachate, waste incineration plant leachate, garbage comprehensive treatment site leachate and garbage Transfer station leachate. Since leachate is a kind of high-concentration organic wastewater with complex components, if it is directly discharged without treatment, it will cause pollution along the road. At present, a large amount of landfill leachate will inevitably be produced in urban waste landfill treatment. The traditional process generally uses garbage The method of backfilling after the leachate is concentrated is processed, and its existing problem is that: the domestic waste leachate is a kind of high-concentration degraded sewage containing various salts (including heavy metal sal...

Problems solved by technology

Since the leachate is a kind of high-concentration organic wastewater with complex components, if it is directly discharged without treatment, it will cause pollution along the road. At present, a large amount of landfill leachate will inevitably be produced in the urban waste landfill treatment. The traditional process generally uses garbage The method of backfilling after the leachate is concentrated is processed, and its existing problem is that: the domestic waste leachate is a kind of high-concentration degraded sewage containing various salts (including heavy metal salts), especially the leachate produced by the landfill can hardly biochemically deal with

[0004] In the above-mentioned device, the dry salt will be blown and scraped by hot air during the falling process, but the falling time of the dry salt is very short. It is difficult to completely treat the organic matter in the salt in this short oxidation blowing process. Repeated blowing and oxidation, the processing efficiency of this processing equipment is low, and it also requires the staff to rotate the material several times, wasting manpower
