Two-stage submerged combustion and evaporation integrated device

Abstract

The present invention involves a two -stage immersion and combustion and evaporate integrated device. It includes a single -form evaporative tank. The inside of the evaporation tank has two evaporation rooms.The two evaporate rooms, thereby achieving two -stage immersion and burning evaporation in an evaporation tank.The number of evaporators and various types of gas and liquid transportation pipelines, save energy, save the area and cost, while simplifying the processing process and facilitate operation management.

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
