Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a curtain evaporator for natural evaporation of wastewater. Background Technology

[0002] In livestock waste treatment, the final step in wastewater treatment is through a curtain evaporation process. Curtain evaporation effectively reduces wastewater discharge, achieving zero or near-zero discharge targets. Water can be recovered during the evaporation process, reducing resource waste. Evaporation reduces moisture content, decreases sludge volume, and lightens the burden on subsequent treatment processes. The curtain evaporation process is characterized by high efficiency, low energy consumption, simple operation, and adaptability to various climatic conditions and wastewater characteristics.

[0003] In wastewater evaporation systems, the use of air curtains for extended periods necessitates periodic disassembly and the application of preservatives or antibacterial agents. Otherwise, pathogens and algae may proliferate in the wastewater, impacting air quality and system efficiency; unpleasant odors may develop, affecting the surrounding environment; and the biodegradation of the air curtain material may accelerate, shortening its lifespan. The disassembly and reinstallation of air curtains are cumbersome and time-consuming, potentially leading to system downtime, reduced treatment efficiency, and increased labor costs. Improper installation can also result in loose connections. Therefore, we propose an air curtain evaporation device for natural wastewater evaporation to address these issues. Utility Model Content

[0004] This utility model provides an air curtain evaporation device for natural evaporation of wastewater, which solves the problem that the surface of the air curtain needs to be disassembled regularly to add preservatives or antibacterial agents. Disassembly and reinstallation take time, which may cause system downtime, affect processing efficiency, and increase additional labor costs. Improper installation may also lead to loose connections.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a wind curtain evaporation device for natural evaporation of wastewater, including a frame, a bottom pool at the bottom of the frame, a rotating drum on the bottom pool, multiple circumferential arrays of wind screens around the drum, multiple vertical grooves on the drum, and a lifting spray pipe on the drum, the lifting spray pipe including a first spray pipe that can be raised and lowered against the vertical groove.

[0006] In the preferred embodiment, the frame includes a polygonal support frame, a ladder is provided on the polygonal support frame, and multiple support rods are provided at the bottom of the polygonal support frame.

[0007] In a preferred embodiment, the bottom pool includes a polygonal pool body, on which multiple support rods are provided, and on which multiple support rods are rotating seats. A lift pump is connected to one side of the polygonal pool body.

[0008] In a preferred embodiment, a spraying device is provided at the top of the frame. The spraying device includes multiple second spray pipes, each with multiple second nozzles. The multiple second spray pipes are connected to the main pipe, and the main pipe is connected to the booster pump via a pipeline.

[0009] In a preferred embodiment, the rotating cylinder includes a hollow annular cylinder with multiple arc-shaped plates. The top of each arc-shaped plate has a first flat-bottom hole, and vertical grooves are provided between adjacent arc-shaped plates. The annular cylinder has multiple second flat-bottom holes, and a rotating shaft is provided at the bottom of the annular cylinder. The rotating shaft abuts against a rotating seat and rotates.

[0010] In the preferred embodiment, the rotating drum is provided with ring frames at both ends. The ring frames include ring frame tubes, and multiple connecting rods are provided on the ring frame tubes. The connecting rods are connected to the rotating drum, and lifting rings are provided on the ring frame tubes.

[0011] In a preferred embodiment, the windscreen is provided with support rods at both ends. One end of the top support rod abuts against the first flat bottom hole, and the other end of the top support rod abuts against the lifting ring. One end of the bottom support rod abuts against the second flat bottom hole, and the other end of the bottom support rod abuts against the lifting ring.

[0012] In a preferred embodiment, the lifting spray pipe includes a housing, a motor is mounted on the housing, a gear is mounted on the output end of the motor, a meshing rack is mounted on the gear, a first spray pipe is mounted on the top of the rack, and multiple first nozzles are mounted on the first spray pipe.

[0013] In the preferred embodiment, a vertical rod is provided at the bottom of the box body, which is connected to the rotating drum. A second box body is provided at the bottom of the rotating drum, and the second box body is connected to the first spray pipe through a flexible hose.

[0014] The beneficial effects of this utility model are as follows: The bottom pool is connected to the anaerobic fermentation tank through a pipe. Multiple air curtains are installed on the rotating drum. After anaerobic fermentation of the liquid, the liquid is transferred to the spraying device via a lift pump. The spraying device sprays the liquid onto the air curtains. The air curtains use wind power to rotate the rotating drum. The air curtains achieve zero emissions through evaporation via wind power and sunlight. The air curtain evaporation process features high-efficiency evaporation, low energy consumption, and simple operation. When preservatives or antibacterial agents need to be added to the air curtains, the ring frame is manually supported to rotate the rotating drum, driving the motor to rotate the gears, causing the rack to move downwards, allowing the first spray pipe to slide against the vertical groove. This drives the first nozzle, allowing the preservative or antibacterial agent in the second chamber to be sprayed onto the air curtain surface through the first nozzle. When the first spray pipe moves to the lowest point, the driving motor is reversed to move the first spray pipe upwards, allowing it to move out of the vertical groove. The ring frame is rotated to rotate the rotating drum, and the first spray pipe is positioned at the top of the next vertical groove. The lifting and lowering of the spray pipe and the spraying are repeated until all air curtain surfaces are sprayed with preservatives or antibacterial agents. The lifting spray pipes can move up and down to ensure that all surfaces of the air screens are sprayed. This avoids the time required for disassembling and reinstalling the air screens, which could lead to system downtime, reduced processing efficiency, and increased labor costs. Improper installation may also result in loose connections, making this system highly valuable for wider application. Attached Figure Description

Detailed Implementation

[0026] Example 1:

[0027] like Figure 1-9 The air curtain evaporation device for natural evaporation of wastewater includes a frame 1, a bottom pool 3 at the bottom of the frame 1, a rotating drum 2 on the bottom pool 3, multiple circumferentially arrayed air screens 7 around the drum 2, multiple vertical grooves 206 on the drum 2, and a lifting spray pipe 5 on the drum 2. The lifting spray pipe 5 includes a first spray pipe 505 that can move up and down within the vertical grooves 206. With this structure, the bottom pool 3 is connected to an anaerobic fermentation tank via pipes. After anaerobic fermentation of the liquid, a lift pump 9 transfers the liquid to the spray device 6, which sprays it onto the air screens 7. The air screens 7 use wind power to rotate the drum 2. The air screens 7 achieve zero emissions through evaporation using wind power and sunlight. The air curtain evaporation process features high-efficiency evaporation, low energy consumption, and simple operation. When the air screen 7 needs additional preservatives or antibacterial agents, manually support the ring frame 4 to rotate the drum 2, drive the motor 502 to rotate the gear 503, and move the rack 504 downwards so that the first spray pipe 505 slides against the vertical groove 206, driving the first nozzle 506 to spray the preservative or antibacterial agent in the second chamber onto the surface of the air screen 7. When the first spray pipe 505 reaches the lowest point, drive the motor 502 to move the first spray pipe 505 upwards, so that the first spray pipe 505 moves out of the vertical groove 206. Rotate the ring frame 4 to rotate the drum 2, and the first spray pipe 505 is positioned at the top of the next vertical groove 206. Repeat the raising and lowering of the spray pipe 5 and spraying until all surfaces of the air screen 7 are sprayed with preservatives or antibacterial agents. The raising and lowering spray pipe 5 can move up and down to ensure that all surfaces of the air screen 7 are sprayed. To avoid the time required for disassembling and reinstalling the wind screen 7, which could lead to system downtime, affect processing efficiency, and increase additional labor costs, improper installation could result in loose connections.

[0028] In the preferred embodiment, frame 1 includes a polygonal support frame 101, a ladder 102 mounted on the polygonal support frame 101, and multiple support rods 103 at the bottom of the polygonal support frame 101. With this structure, the shape of the polygonal support frame 101 is the same as the shape of the polygonal pool body 301. Both the polygonal support frame 101 and the polygonal pool body 301 are preferably hexagonal to facilitate the installation of the polygonal support frame 101 within the polygonal pool body 301. The ladder 102 mounted on the polygonal support frame 101 facilitates maintenance work by personnel.

[0029] In a preferred embodiment, the bottom tank 3 includes a polygonal tank body 301, with multiple support rods 303 mounted on the polygonal tank body 301.

With this structure, the bottom tank 3 is connected to the anaerobic fermentation tank via a pipe. Multiple air screens 7 are mounted on the rotating drum 2. After liquid anaerobic fermentation, the wastewater liquid in the bottom tank 3 is transferred to the spray device 6 via the lift pump 9, and the spray device 6 sprays the liquid onto the air screens 7.

[0030] In a preferred embodiment, a spraying device 6 is provided at the top of the frame 1. The spraying device 6 includes a plurality of second spray pipes 601, and a plurality of second nozzles 602 are provided on the second spray pipes 601. The plurality of second spray pipes 601 are connected to the main pipe, and the main pipe is connected to the lift pump 9 through a pipeline.

[0031] In a preferred embodiment, the rotating drum 2 includes a hollow annular cylinder 201 with multiple arc-shaped plates 202. Each arc-shaped plate 202 has a first flat-bottomed hole 203 at its top, and vertical grooves 206 between adjacent arc-shaped plates 202. The annular cylinder 201 also has multiple second flat-bottomed holes 204, and a rotating shaft 205 at its bottom, which rotates against a rotating seat 302. With this structure, the bottom of the rotating drum 2 has multiple third through holes. When liquid sprayed onto the air screen 7 splashes into the rotating drum 2, the splashed liquid drains into the bottom pool 3 through the third through holes. Natural wind blows onto the multiple air screens 7, causing the rotating drum 2 to rotate relative to the bottom pool 3, thus accelerating evaporation of the air screens 7. The air screens 7, through natural wind and solar energy, achieve zero or near-zero emissions.

[0032] The wind screen 7 uses wind energy to rotate the rotating drum 2. The wind screen 7 achieves zero emissions through evaporation using wind energy and sunlight. The wind curtain evaporation process features high-efficiency evaporation, low energy consumption, and simple operation.

[0033] In the preferred embodiment, the rotating drum 2 is provided with ring frames 4 at both ends. The ring frame 4 includes a ring frame tube 401, and multiple connecting rods 402 are provided on the ring frame tube 401. The connecting rods 402 are connected to the rotating drum 2, and lifting rings 403 are provided on the ring frame tube 401. With this structure, when the air screen 7 needs to add preservatives or antibacterial agents, the ring frame 4 can be manually supported to make the rotating drum 2 rotate.

[0034] In a preferred embodiment, the air screen 7 is provided with support rods 8 at both ends. One end of the top support rod 8 abuts against the first flat-bottom hole 203, and the other end abuts against the lifting ring 403. One end of the bottom support rod 8 abuts against the second flat-bottom hole 204, and the other end abuts against the lifting ring 403. This structure allows the air screen 7 to be easily removed from the structure of the rotating drum 2 and the ring frame 4, facilitating replacement by personnel when the air screen 7 is damaged after prolonged use.

With this structure, when the air screen 7 needs additional preservatives or antibacterial agents, the ring frame 4 is manually supported to rotate the drum 2, driving the motor 502 to rotate the gear 503, causing the rack 504 to move downwards, allowing the first spray pipe 505 to slide against the vertical groove 206, driving the first nozzle 506 to spray the preservative or antibacterial agent in the second housing onto the surface of the air screen 7. When the first spray pipe 505 moves to the lowest point, the motor 502 is driven to move the first spray pipe 505 upwards, allowing it to move out of the vertical groove 206. The ring frame 4 is then rotated to rotate the drum 2, positioning the first spray pipe 505 at the top of the next vertical groove 206. This process of raising and lowering the spray pipe 5 and spraying continues until all surfaces of the air screen 7 are sprayed with preservatives or antibacterial agents. The lifting spray pipe 5 can move up and down to ensure that all surfaces of the air screen 7 are sprayed. To avoid the time required for disassembling and reinstalling the wind screen 7, which could lead to system downtime, affect processing efficiency, and increase additional labor costs, improper installation could result in loose connections.
