Abstract

The invention discloses a garbage leachate treatment system, which comprises an evaporator, a heater and a steam compressor, wherein the evaporator is provided with a steam outlet, a garbage leachate feeding pipe, a concentrated solution reflow pipe and a concentrated solution outlet; a concentrated solution inlet, a heater steam inlet, a concentrated solution outlet, a condensed water outlet and a non-condensed steam outlet are formed in the heater; the steam outlet of the evaporator is connected to the steam compressor; an outlet of the steam compressor is communicated with the heater steam inlet of the heater; the concentrated solution outlet of the evaporator is partitioned into two paths, wherein one path is communicated to a concentrated solution discharging pump, and the other path is communicated to a forced circulation pump; the forced circulation pump is communicated to the concentrated solution inlet of the heater; the concentrated solution outlet of the heater is communicated to the concentrated solution reflow pipe of the evaporator. Secondary steam generated by an evaporation system is mainly taken as a heat source of the evaporation system. Secondary steam is recycled as a heat source.

Description

technical field [0001] The invention relates to a garbage leachate treatment system, in particular to an evaporation system for treating garbage leachate in a garbage incineration plant with low cost, low energy consumption and convenient operation and management, belonging to the technical field of wastewater treatment. Background technique [0002] With the acceleration of the pace of urbanization in our country, the growth of population and the improvement of people's living standards, urban domestic waste is also increasing day by day. At present, the methods of waste treatment and disposal mainly include landfill, composting, incineration, etc. Compared with traditional landfill and composting, incineration has the advantages of reduction, harmlessness, and resource utilization. has been well developed. [0003] In order to ensure the efficiency of incineration in the process of garbage incineration, fresh garbage needs to be fermented in the garbage storage pit for 3 ...
