Abstract

The invention relates to a composite water treatment system based on near-field thermophotovoltaic waste heat utilization, and aims to solve the problem of low efficiency of the technology of recovering waste heat for water treatment in the prior art, and the purposes of photovoltaic cell heat dissipation and water resource acquisition are achieved at the same time by combining near-field thermophotovoltaic, radiation refrigeration, solar distillation, multi-stage flash evaporation and other technologies. The water to be treated in the application has dual effects in the circulation process: the photovoltaic cell is cooled, so that the cell can be maintained at a normal working temperature; and waste heat generated by the near-field thermophotovoltaic system is absorbed, purified water is obtained through the flash evaporation device, and secondary utilization of energy is achieved. According to the invention, solar energy is utilized to further improve the yield of purified water; the liquid flowing direction is simple, pipeline arrangement is convenient, actual installation of equipment is facilitated, and efficiency is high.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a composite water treatment system based on near-field thermal photovoltaic waste heat utilization. Background technique [0002] Thermal photovoltaic technology is an energy utilization technology that converts the radiant energy emitted by the radiator into electrical energy through photovoltaic cells. The limitation of Stefan-Boltzmann law greatly improves the system efficiency. However, since the radiation source temperature of near-field thermal photovoltaic systems is mostly above 1000K, photovoltaic cells are faced with huge heat dissipation pressure, which seriously limits the application of this technology in practice. [0003] The existing technology of recovering waste heat for water treatment has problems such as low overall efficiency, high operating cost, and complex equipment structure, which limit its development and application in actual production. ...
