The embodiment can prepare ultrapure water by utilizing solar energy and can prepare hot water by secondarily utilizing heat.
In some embodiments, the water replenishment control system comprises a first water replenishment pipeline, a second water replenishment pipeline, a low level control valve and a high level control valve, wherein the first water replenishment pipeline is communicated with the bottom of the interlayer and/or the upper end of the solar vacuum tube collector connecting box, the second water replenishment pipeline is communicated with the inner barrel, the low level control valve is connected with the first water replenishment pipeline, and the high level control valve is connected with the second water replenishment pipeline.

The upper end of the connecting box 17 is higher than the uppermost vacuum heat collecting tube 18 and is communicated with the bottom of the interlayer 5. A drain 21 is provided at the lower end of the connecting box 17.
The water in the solar vacuum tube heat collector connecting box 3 is kept to overflow the bottom of the heat preservation barrel 1, so that the liquid level is positioned in the interlayer 5, the solar vacuum tube heat collector connecting box 3 absorbs solar heat to heat tap water in the solar vacuum tube heat collector connecting box, and hot water in the solar vacuum tube heat collector connecting box 3 enters the interlayer 5 due to density difference. Due to the movement of the hot molecules, the hot water below the boiling point evaporates as single molecules on the surface, yielding ultra-pure gaseous water. Tap water at normal temperature is arranged in the inner barrel 2, ultra-pure gaseous water is condensed on the outer surface of the inner barrel 2, and flows down into the ultra-pure water collecting tank 6 along the outer wall of the inner barrel 2, and ultra-pure water is taken through the ultra-pure water outlet pipe 8.

The low-position control valve 11 and the high-position control valve 12 are all fully automatic water level control valves which are commercially available. For example, the fully automatic water level control valve may employ a float valve principle, which is capable of automatically opening and closing in response to a change in the liquid level in a container in communication therewith, using a communicating vessel principle when it is connected to the container through a communicating tube. By reasonably setting the installation height of the low-level control valve 11, water in the solar vacuum tube collector connecting box 3 can be kept from overflowing into the interlayer 5, and the water surface in the interlayer 5 is kept not to exceed the ultrapure water collecting tank 6, so that hot water can be directly evaporated above the interlayer 5, and water in the interlayer 5 can be prevented from overflowing into the ultrapure water collecting tank 6. The high-level control valve 12 is disposed at a higher position, and since the high-level control valve 12 communicates with the inner tub 2, the water surface of the high-level control valve 12 is flush with the water surface of the inner tub 2.

In some embodiments, a first water inlet 19 is arranged on the lower side surface of the upper end of the connecting box 17 of the solar vacuum tube collector connecting box, and the first water inlet 19 is connected with the water supplementing control system 4. The connecting box 17 is in an inclined state, and the first water supplementing port 19 is arranged on the lower side surface of the upper end of the connecting box 17. Specifically, the first water replenishment pipe 9 of the replenishment control system 4 is connected to the first water replenishment port 19. Preferably, the first water supplementing pipeline 9 adopts a thinner pipe, so that the water circulation speed is low, the temperature of tap water in the connecting box is higher, and the evaporation speed is higher as the temperature of water is higher.
In some embodiments, the upper end of the junction box 17 is provided with an electric auxiliary heating device 20 at a position slightly below the upper end. An electric auxiliary heating port is reserved at the top end of the connecting box 17, and an automatic temperature control electric heating pipe with the power of 1500-3000 watts can be installed. Under the premise of switching on a power supply, when the water temperature is lower than 75 ℃, the electric heating function is automatically started, so that the ultra-pure water is produced when a user uses hot water.
