Problems solved by technology

Evaporation and crystallization is an important way to achieve zero discharge of salty wastewater. Common evaporation and crystallization methods include multi-effect evaporation, mechanical vapor compression, etc. However, the inventor believes that due to its relatively high evaporation temperature, most of the low-grade waste heat Unusable, high energy consumption and high investment are the technical bottlenecks of the current evaporation crystallization method. Therefore, the key problem of zero discharge of wastewater is the lack of technical and economically feasible recycling methods for high-salt industrial wastewater at the end of the enterprise.

Abstract

The invention belongs to the technical field of industrial wastewater treatment, and in particular relates to an adsorption-type water purification refrigeration system driven by industrial waste heat and its application. The system is mainly composed of the first adsorption bed, the second adsorption bed, evaporator, condenser, heat exchange fluid circuit, valves, water pump and so on. The system can produce cooling effect while purifying industrial sewage. According to the needs of different seasons, it can switch between two working conditions of water purification refrigeration and water purification. In addition, the system of the present invention is driven by low-grade industrial waste heat, which solves the problems of low utilization rate of industrial waste heat and high energy consumption of conventional desalination technology mentioned in the above-mentioned background technology, and can realize desalination of seawater, purification or concentration of waste water, and simultaneously produces Cooling effect.

Description

technical field [0001] The invention belongs to the technical field of industrial wastewater treatment, and in particular relates to an adsorption-type water purification refrigeration system driven by industrial waste heat and its application. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and it is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] my country's low-grade industrial waste heat utilization potential is huge, but the utilization rate is not high, most of them are discharged by water cooling, and a few are directly discharged by air cooling. In order to discharge this part of waste heat, the factory has to consume a lot of water. On the other hand, with the gradually stricter emission standards for...
