Description

Technical Field

[0001] This invention relates to the field of distiller technology, specifically to a fully solar-powered triple distiller. Background Technology

[0002] Triple distillation of water is an important method for removing various impurities from water through three consecutive stages of vaporization and condensation to obtain water of extremely high purity. It is mainly used in scientific and technological fields with high purity requirements, such as life sciences, analytical chemistry, and semiconductor manufacturing.

[0003] With the continuous advancement of intelligent and automated technologies, modern equipment generally integrates functions such as water level controllers, anti-dry-burning protection, and automatic water and power shut-off. The introduction of the Internet of Things and artificial intelligence enables equipment to remotely monitor its operating status and dynamically optimize heating parameters, significantly improving operational stability and safety. Although technologies such as high-efficiency quartz tube heating, multi-layer insulation structures, and waste heat recovery systems have been used to overcome the high energy consumption of triple distillation equipment, the electricity consumption for producing one liter of triple-distilled water is still higher than that of reverse osmosis or electro-deionization technologies; moreover, the water production capacity of a single unit is typically only 1.5 to 5 liters per hour, which cannot meet the needs of large-scale industrial water use.

[0030] Working principle: S1: Under good sunlight conditions, assemble the distillation system and control system together, and add an appropriate amount of water to be distilled into the water tank 2420; S2: Confirm that the combined solar thermal distillation module and the solar photovoltaic panel 2100 are both in normal working condition; S3: Turn on the power supply switch 2110 of the solar photovoltaic panel 2100, and supply power to each power consumption unit under the control of the programmable logic controller 2120; S4: When the level gauge A2610 is not triggered, the shut-off valve A2520 is opened and the shut-off valve B2530 is closed. The circulating water pump 2410 delivers the water to be distilled in the water tank 2420 through the water inlet 2421, condenser C1330, condenser B1320, condenser A1310, three-way pipe 2510, shut-off valve A2520, liquid inlet 11123 and liquid inlet pipe 11124 into the distillation pipe 11121. S5: When the level gauge A2610 is triggered, the shut-off valve A2520 closes and the shut-off valve B2530 opens. The circulating water pump 2410 transports the water to be distilled in the water tank 2420 back to the water tank 2420 through the water inlet 2421, condenser C1330, condenser B1320, condenser A1310, three-way pipe 2510, shut-off valve B2530 and return water inlet 2422. S6: Start the circulating air pump 2300 to draw the water vapor and non-condensable gas in the first distillation tube 11121 together into the condenser A1310 through the steam outlet 11126. In the condenser A1310, the water vapor is converted into primary distilled water, which then enters the second distillation tube 11221 through the second air inlet 11222 and the second liquid inlet pipe 11224 for secondary distillation. S7: When the level gauge B2620 is not triggered, the drive motor A2211 of the light blocker A2210 unfolds the light-blocking curtain A2212, so that the distillation tube 11221 cannot be exposed to sunlight, thereby reducing the temperature of the primary distilled water in the distillation tube 11221 and slowing down the secondary distillation rate. S8: When the level gauge B2620 is triggered, the drive motor A2211 of the light blocker A2210 retracts the light-blocking curtain A2212, allowing the distillation tube 11221 to be fully exposed to sunlight, increasing the temperature of the secondary distilled water in the distillation tube 11221, thereby increasing the secondary distillation rate. S9: The water vapor and non-condensable gas generated in the second distillation tube 11221 enter the condenser B1320 through the steam outlet 11226, and are converted into secondary distilled water in the condenser B1320. The water then enters the third distillation tube 11321 through the air inlet 3 11322 and the liquid inlet pipe 3 11324 for tertiary distillation. S10: When the level gauge C2630 is not triggered, the drive motor B2221 of the light blocker B2220 unfolds the light-blocking curtain B2222, so that the distillation tube 3 11321 cannot be exposed to sunlight, thereby reducing the temperature of the secondary distilled water in the distillation tube 3 11321 and thus slowing down the tertiary distillation rate. S11: When the level gauge C2630 is triggered, the drive motor B2221 of the light blocker B2220 retracts the light-blocking curtain B2222, allowing the distillation tube 3 11321 to be fully exposed to sunlight, increasing the temperature of the secondary distilled water in the distillation tube 3 11321, thereby increasing the tertiary distillation rate. S12: The steam and non-condensable gas produced by the triple distillation enter the condenser C1330 through the steam pipe 11325 and the collection bottle 1200. In the condenser C1330, the steam is converted into triple-distilled water and then returns to the collection bottle 1200 through the return port 1220. The non-condensable gas is discharged from the connection port 1332 on the condenser C1330 and, driven by the circulating air pump 2300, re-enters the distillation tube 11121 through the air inlet 11122 and the liquid inlet pipe 11124 to participate in the distillation process. S13: During the above distillation process, the drainage volume of sewage discharge pumps A2810, B2820 and C2830 is set according to the actual distillation conditions of solar collector stills A1110, B1120 and C1130 respectively, so as to reduce the scaling probability of stills 1112, 1122 and 1132. S14: When the collection bottle 1200 is full of fresh water, turn on the triple water discharge pump 2900 to transport the fresh water to the fresh water storage tank.
