Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of urine evaporation treatment, in particular to a wind energy and solar energy evaporation treatment urine recovery device. BACKGROUND

[0002] Traditional urine treatment technologies (such as biological treatment, chemical precipitation, and membrane separation method) face significant technical and economic bottlenecks in practical application. First, its high energy consumption limits sustainable development: biological treatment relies on continuous aeration to maintain microbial activity, chemical precipitation requires pH adjustment and heating to accelerate the reaction, and membrane separation requires high pressure to drive transmembrane filtration. These processes all rely on external energy input, leading to rising operating costs and exacerbating carbon footprint. Second, low resource recovery efficiency is a key defect. Traditional processes are oriented towards pollutant removal and fail to achieve material recycling. For example, nitrogen and phosphorus nutrients are converted by microorganisms in biological treatment and are mostly disposed of as residual sludge, the phosphate precipitate produced by the chemical precipitation method is difficult to directly resource due to insufficient purity, and membrane separation can intercept some components but is prone to membrane fouling, resulting in declining recovery rate, ultimately causing resource waste and secondary pollution risk. In addition, traditional technologies lack adaptability to application scenarios. Centralized treatment mode relies on stable power supply and large-scale infrastructure, which is difficult to guarantee water supply in water-scarce areas, lacks flexible deployment capability for decentralized sanitation systems (such as rural dry toilets, post-disaster emergency facilities), and cannot meet the stringent demand for water resource closed-loop regeneration in closed scenarios such as space stations and ocean vessels. These limitations highlight the urgency of developing low-carbon, efficient, and scalable new urine treatment technologies.

[0003] Using solar energy as a driving force, light energy is converted into heat energy through a photo-thermal material, directly evaporating water in urine, significantly reducing the carbon footprint of the treatment process. Chinese patent CN113526599A discloses a high-efficiency solar vertical distillation device that uses solar energy to evaporate salt water. However, it does not utilize wind energy, making it difficult to achieve efficient evaporation at night or in areas with low light intensity. Therefore, to achieve continuous and efficient evaporation of urine throughout the day, wind energy needs to be added. However, wind energy can carry away liquid water vapor, which can adversely affect water vapor collection.

[0004] The salt in the evaporation area is also one of the key factors to be considered in the evaporation process. Salt can form crystals in the evaporation area, interfering with the absorption of sunlight. In addition, during the evaporation process, heat is used not only to convert liquid water into gas, but also to heat other water that has not yet evaporated. This part of heat energy will be lost in the form of heat radiation and heat conduction. Therefore, to achieve efficient evaporation of urine, in addition to considering the use of solar and wind energy, we also need to consider the problem of salt crystallization and urine supply. SUMMARY

[0032] Embodiment 1

[0033] Please refer to Figures 1 to 6

[0034] A wind energy and solar energy evaporation treatment urine recovery device, comprising: an evaporation mechanism 1, a wind collecting mechanism 2, a condensation mechanism 3 and an assistant device 4;

[0035] The evaporation mechanism 1 comprises an evaporation fabric 11, a first cloth guide roller 12 and a second cloth guide roller 14, the evaporation fabric 11 is arranged around the first cloth guide roller 12 and the second cloth guide roller 14; the evaporation fabric 11 is used to absorb solar energy and convert it into heat energy for urine evaporation; the first cloth guide roller 12 and the second cloth guide roller 14 jointly drive the evaporation fabric 11 to rotate; the second cloth guide roller 14 guides the evaporation fabric 11 into the urine to make it fully absorb the urine.

[0036] The wind collecting mechanism 2 comprises a windmill 21, a negative pressure fan 22 and a transmission mechanism 23, the windmill 21 is in driving connection with the negative pressure fan 22 and the first cloth guide roller 12 through the transmission mechanism 23, and the windmill 21 is located above the negative pressure fan 22; the windmill 21 is used to collect wind energy and convert it into kinetic energy; the transmission mechanism 23 transmits the kinetic energy to the negative pressure fan 22; the negative pressure fan 22 generates negative pressure to reduce the air pressure on the surface of the evaporation fabric 11, thereby accelerating the evaporation rate of the urine, and because of the low air pressure, urine evaporation can still be achieved even in the absence of light. In addition, the windmill 21 transmits the kinetic energy to the first cloth guide roller 12 through a synchronous wheel and a synchronous belt, so that the evaporation fabric 11 can continuously rotate to realize continuous evaporation of the urine.

[0037] The condensation mechanism 3 includes a condensation back plate 31, a collection tank 32, and a condensation inclined plate 33. The collection tank 32 is located below the condensation inclined plate 33, and the condensation inclined plate 33 is located on one side of the collection tank 32 and the condensation inclined plate 33. The condensation back plate 31 condenses water vapor to form liquid water. The collection tank 32 is used to collect liquid water. The condensation inclined plate 33 is used to assist in the condensation of water vapor and guide liquid water into the collection tank 32.

[0038] The auxiliary device 4 includes an evaporation chamber 41, a condensation chamber 42, a buoyancy plate 43, and a guide plate 44. The evaporation chamber 41 and the condensation chamber 42 together form the outer shell of the device. The buoyancy plate 43 is located at the bottom of the outer shell, and the guide plate 44 is located outside the outer shell. The upper parts of the evaporation chamber 41 and the condensation chamber 42 are connected. A negative pressure fan 22 is located at the connection point between the upper parts of the evaporation chamber 41 and the condensation chamber 42. The evaporation mechanism 1 is located inside the evaporation chamber 41, and the condensation mechanism 3 is located inside the condensation chamber 42. The fan 21 is located outside the auxiliary device 4. The negative pressure fan 22 not only generates negative pressure to reduce the air pressure on the surface of the evaporation fabric 11 and accelerate the evaporation rate of urine, but also, because it is located at the connection point between the upper parts of the evaporation chamber 41 and the condensation chamber 42, it can quickly guide the water vapor evaporated from the urine in the evaporation chamber 41 to the condensation chamber 42 for better and faster condensation. The buoyancy plate 43 provides buoyancy to the entire device, enabling it to float on the urine; the air guide plate 44 enables the evaporator to automatically turn and face the wind direction, improving the utilization rate of wind energy.

[0039] Two sets of first guide rollers 12 and one set of second guide rollers 14 are located on either side above the second guide rollers 14. The first guide rollers 12 and the second guide rollers 14 guide the end sides of the evaporating fabric 11 into a triangular shape. The triangular evaporating fabric 11 allows it to remain in the urine for a longer time, thus absorbing the urine better. Compared to a square structure, the structure is simpler and helps save space.

[0040] The evaporation mechanism 1 also includes a pressure roller 13 and a salt scraper 15. The pressure roller 13 is disposed on the conveying path of the evaporating fabric 11 and contacts the surface of the evaporating fabric 11. The salt scraper 15 is disposed on the outer surface of the evaporating fabric 11 and is in frictional sliding connection with the evaporating fabric 11. The pressure roller 13 squeezes the evaporating fabric 11 to remove excess urine and regulates the amount of urine adhering to the fabric surface. The salt scraper 15 scrapes off salt crystals on the evaporating fabric 11 to prevent salt from clogging the fabric surface and reducing the evaporation rate.

[0041] The evaporation fabric 11 is a black polyester / cotton fabric with a warp density of 24 threads / cm, a weft density of 10 threads / cm, and a thickness of 0.5mm. This ensures that it can adhere to a certain amount of urine while also being corrosion-resistant.

[0042] Auxiliary device 4 is made of transparent acrylic sheet. Transparent acrylic sheet is corrosion-resistant and highly permeable, allowing sunlight to penetrate more easily.

[0043] The condenser back plate 31 and the condenser inclined plate 33 are made of copper plate with a thickness of 1mm to ensure the condensation effect.

[0044] The speed ratio of the windmill 21 to the first guide roller 12 via the transmission mechanism 23 is 2:1, which ensures the stability of urine evaporation.

[0045] The collection tank 32 is installed in the condensation chamber 42 of the auxiliary device 4 by a pull-out mechanism. This allows for easy removal of the collection tank 32 to collect condensate.

[0046] The condenser backplate 31 has continuous small holes 34 on its back, and a row of heat-conducting fins 35 at its bottom. The small holes 34 are used to expel ammonia gas. The heat-conducting fins 35 are in contact with the urine, conducting heat downwards to ensure that the temperature of the condenser backplate 31 remains below the temperature of water vapor.

[0047] The components of the evaporation mechanism 1, the air collection mechanism 2, and the condensation mechanism 3 are made of polyvinyl chloride plastic, ensuring the resistance to urine corrosion and lightweight design of the entire internal transmission system.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
