Wastewater evaporation, concentration and reduction integrated device

Abstract

The invention relates to a wastewater evaporation, concentration and reduction integrated device. The device is composed of a box body, an evaporation unit, a circulating fan, a heating unit, a condensation unit, a condensate water purification unit, a control unit, an auxiliary pipeline and a partition plate. An evaporation plate in the device is used for direct contact evaporation of hot dry airand wastewater, a condenser cools and dehumidifies hot wet air, an electric heater heats circulating air, a circulating fan enables the air to circularly flow in the system, and a multilayer filtering system continuously purifies water condensed to a bottom water collecting tank to form standard-reaching return water. The air cooler is used for generating circulating cooling water, and wastewaterof the evaporation unit is placed in a push-pull type waste liquid tank, so that the wastewater can be conveniently supplemented, and the concentrated wastewater can be conveniently replaced. The boxbody is wrapped with a heat preservation layer and adopts a self-control unit in order to improve the efficiency and reliability of the system, so the device can be conveniently run and managed; andthe device has the advantages of short technological process, simple device structure, convenience in maintenance, and realization of clean and environmentally-friendly treatment of high-concentrationwastewater.

Description

technical field [0001] The invention relates to an air-waste direct contact evaporative concentration treatment device, in particular to a waste water evaporative concentration and reduction integrated device, which belongs to the technical field of environmental protection and reduction treatment of refractory high-concentration industrial waste water. Background technique [0002] In recent years, the domestic requirements for environmental protection have become higher and higher, and the supervision of the discharge of a small amount of waste water has been put on the agenda. For example, the experimental waste water and flushing waste water generated by scientific research institutes every day are no longer allowed to be directly discharged into the sewer pipes. Laboratory wastewater must be centrally stored and transported to hazardous waste centers for treatment, and various types of wastewater generated in hospitals must be professionally treated. This type of wastew...
