Description

Technical Field

[0002] Double-effect evaporation device is a device that uses heat energy to evaporate wastewater. Its working principle is to heat wastewater to boiling state, evaporate water and recover it. It is usually composed of two evaporators in series. The first evaporator (first effect) uses an external heat source to heat wastewater to generate steam; this steam then enters the second evaporator (second effect) and serves as a heat source to heat the wastewater entering the second effect, thereby achieving evaporation of wastewater.

[0003] The first evaporator heats the wastewater with the help of an external heat source. The external heat source is basically a simple heating component that can only play a single heating role. The liquid temperature close to the external heat source is high, and the evaporation rate will be relatively fast, while the liquid temperature far from the heat source is low, and the evaporation will be slow. This will lead to uneven evaporation of the wastewater, and there may be large differences in local evaporation effects, affecting the overall evaporation efficiency and effect. In order to address this problem, a heater for a double-effect evaporation device is proposed. Utility Model Content
