Two-stage immersing, combusting and evaporating integrated device

Abstract

The invention relates to a two-stage immersing, combusting and evaporating integrated device. The two-stage immersing, combusting and evaporating integrated device comprises an evaporation tank in a single form, wherein two evaporation chambers are formed in the evaporation tank; a treatment fluid can flow from a first evaporation chamber into a second evaporation chamber through a communicated area at the inner bottom of the tank, so that two-stage immersion, combustion and evaporation in one evaporation tank is achieved. The number of evaporators and various gas and liquid conveying pipelines is reduced, the energy is saved, and the floor area and the cost are reduced; moreover, the treatment process is simplified and operation management is facilitated.

Description

technical field [0001] The invention relates to the technical field of high-salt organic waste liquid treatment for environmental protection, in particular to the evaporation concentration treatment technology of landfill leachate. Background technique [0002] The treatment of landfill leachate has always been an important topic in the comprehensive disposal of domestic waste in my country. my country's domestic waste has a high water content, a large leachate output and a high concentration of pollutants, and a wide range of water quality changes. The difficulty of treatment is significantly higher than that of developed countries in Europe and the United States. [0003] The leachate contains a large amount of easily degradable and refractory organic matter, ammonia nitrogen and inorganic salts, etc. Biological treatment is currently the most important treatment technology, which can remove most easily degradable organic matter and convert ammonia nitrogen into nitrate ni...

AI Technical Summary

Problems solved by technology

[0006] First, the number of equipment used is large and the area is large;

[0007] Second, the transportation pipes of various gases and liquids are long, the investment is large, and the available high-temperature steam dissipates a lot of heat during long-distance transportation;

[0008] Third, it is necessary to control multiple evaporation tanks, the process is complicated and the management is inconvenient
