Abstract

The invention discloses a double-stage solar seawater desalination device. The double-stage solar seawater desalination device includes a primary water tank, the primary water tank is connected to a condenser through a first electromagnetic valve, the condenser is connected to a photothermal water tank through a second electromagnetic valve, the photothermal water tank is connected to a photoelectric water tank through a first water pump, the photoelectric water tank is connected to a condenser through a second water pump, the condenser is connected to a fresh water tank, and the fresh water tank is connected to the photoelectric water tank through a third water pump. A heater is disposed below the photoelectric water tank, the first electromagnetic valve, the second electromagnetic valve, the first water pump, the second water pump, the third water pump and the heater are connected to the controller. The controller, the first electromagnetic valve, the second electromagnetic valve, the first water pump, the second water pump, the third water pump, the heater and an ultraviolet lamp are connected to a solar power generation mechanism. The photothermal water tank is also connected to a solar heat collection pipe. The invention also provides a double-stage solar seawater desalination method. The device and the method provided by the invention can reduce energy consumption and provide high quality fresh water.

Description

technical field [0001] The invention belongs to the technical category of green new energy utilization, and specifically relates to a two-stage solar desalination device and a desalination method. Background technique [0002] On isolated islands and life-saving devices where fresh water resources are scarce, the source of fresh water mainly depends on two methods: rainwater collection and seawater desalination. Due to the uncertainty of time and water volume, the fresh water collected by rainwater is difficult to guarantee the daily needs of residents. Although seawater desalination can increase freshwater resources according to demand, it consumes a lot of energy (this is because most isolated islands use traditional energy (coal, oil) to generate electricity, and seawater desalination consumes a lot of power, so traditional energy (coal, oil) consumes larger). In addition, the desalination effect of the existing seawater desalination device is not very ideal, and the fr...
