Example Embodiment
[0013] Specific embodiment 1: The method of applying the solar evaporation device to process the membrane concentrate in this embodiment is implemented in the following steps:
[0014] 1. The solar evaporator includes a solar heat collection unit 1, an evaporator 2, a condenser 3 and a preheating device 4. The solar heat collection unit 1 includes a solar heat collector 101 and a heat medium storage tank 102, and the heat medium storage tank 102 The heat medium flows into the solar collector 101 through the heat medium input pipe 103 for heating, and then flows into the three-way valve 109 through the heat medium output pipe 104 to mix with the heat medium from the heat medium return pipe 208, and pass through the warm medium. The control knob 110 stably outputs the heat medium with a temperature of 120~180℃, and then flows into each parallel heat medium coil heat exchanger 203 through the heat medium transportation pipeline 202, and the heat medium coil heat exchanger 203 is loca...
Example Embodiment
[0017] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the solar evaporation device includes a solar heat collection unit 1, an evaporator 2, a condenser 3, and a preheating device 4. The solar heat collection unit 1 includes solar energy. The heat collector 101 and the heat medium storage tank 102. The inlet of the solar heat collector 101 is connected to the liquid outlet of the heat medium storage tank 102 through the heat medium input pipe 103. One end of the heat medium return pipe 208 is connected to the heat medium storage tank 102. The liquid inlet is connected, the other end of the heat medium return pipe 208 is respectively connected to the liquid outlet of each heat medium coil heat exchanger 203, and the outlet of the solar collector 101 is connected to the three-way valve 109 through the heat medium output pipe 104 One end of the branch pipe 111 is connected to the heat medium return pipe 208, and the other end of the branch pipe 111 is...
Example Embodiment
[0022] Specific embodiment three: This embodiment is different from specific embodiments one or two in that a first liquid pump 105 is provided in the heat medium input pipe 103.
