Description

Technical Field

[0001] This utility model relates to an organic wastewater heat recovery and cooling device, belonging to the technical field of heat exchange equipment. Background Technology

[0002] Organic wastewater heat recovery and cooling devices integrate wastewater treatment and heat recovery functions, aiming to treat organic wastewater while recovering its heat energy. During operation, organic wastewater flows counter-currently or concurrently with another low-temperature working fluid (such as cooling water) within the device to achieve heat transfer. Organic wastewater typically contains flocculent or particulate matter. This flocculent or particulate matter, after entering the device, deposits on the heat exchange walls, forming a fouling layer that increases thermal resistance and reduces the device's heat recovery efficiency. Furthermore, the device's heat exchange efficiency is also affected by the flow rate of the organic wastewater. Traditional similar devices usually require both mechanisms for filtering flocculent or particulate matter from the organic wastewater and mechanisms for regulating the wastewater flow rate. Utility Model Content

Through the control and filtration components, it can not only adjust the flow rate of organic wastewater, but also filter and retain the flocculent or particulate matter carried in the organic wastewater.

Detailed Implementation

[0025] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0026] It should be noted that many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figures 1-3 As shown, the organic wastewater heat recovery and cooling device provided by this utility model includes a heat exchanger 100, on which a coolant pipe 200 and a wastewater pipe 300 are connected. During operation, cooling water and organic wastewater are introduced into the heat exchanger 100 from the coolant pipe 200 and the wastewater pipe 300, respectively, for heat exchange.

[0028] The wastewater pipe 300 is equipped with a flow control and filtration component 400. The flow control and filtration component 400 is used to regulate the flow rate of wastewater and to filter and retain flocculent or particulate matter in the wastewater to prevent a large amount of flocculent or particulate matter from entering the heat exchanger 100 and affecting the heat exchange efficiency.

[0029] Specifically, the flow control and filtration assembly 400 includes an outer pipe 410, an inner pipe 420, and a core pipe 430, all coaxially arranged with the wastewater pipe 300, as well as a drive assembly.

[0030] The outer pipe 410 has a larger diameter than the wastewater pipe 300, and both the upstream and downstream ports of the outer pipe 410 are connected to the wastewater pipe 300.

[0031] The upstream port of the inner pipe 420 is closed, and the downstream port is open.

[0032] The upstream port of the core tube 430 is closed with an end plate 431, while the downstream port is open. The upstream section of the core tube 430 is slidably disposed within the inner tube 420. The upstream section of the core tube 430 has a closed wall, while the downstream section has holes 432 for installing a filter screen. The downstream section of the core tube 430 is slidably disposed within the wastewater pipe 300. The outer diameter of the core tube 430 matches the inner diameter of both the inner tube 420 and the wastewater pipe 300, ensuring that the upstream section of the core tube 430 is supported by the inner tube 420, and the downstream section is supported by the wastewater pipe 300. The filter screen is not shown in the figure; in actual applications, a filter screen with the required aperture size can be installed as needed. A metal filter screen can be used and directly welded to the holes 432 for fixation.

[0033] The drive assembly is used to drive the core tube 430 to slide along the axis to adjust the exposed area of ​​the downstream section hole 432 of the core tube 430 in the outer tube 410.

[0034] In practical applications, organic wastewater first enters the outer pipe 410 from the upstream wastewater pipe 300, then flows downstream through the annular space between the outer pipe 410 and the inner pipe 420, then passes through the filter screen installed on the hole 432 in the downstream section of the core pipe 430, and continues to flow into the downstream wastewater pipe 300, and finally enters the heat exchanger 100. The flocculent or particulate matter carried in the organic wastewater is intercepted by the filter screen.

[0035] When the core tube 430 slides along the axis via the drive assembly, the exposed area of ​​the downstream section of the core tube 430's orifice 432 within the outer tube 410 changes accordingly. For example, when the core tube 430 moves to the left, the exposed area of ​​the orifice 432 increases, and the flow rate of the organic wastewater increases. When the core tube 430 moves to the right, the exposed area of ​​the orifice 432 decreases, and the flow rate of the organic wastewater decreases.

[0036] Furthermore, a first sealing ring 421 is provided on the inner wall of the downstream port of the inner tube 420. The first sealing ring 421 is in sealing contact with the outer wall of the core tube 430 to prevent organic wastewater from entering the inner tube 420. A second sealing ring 310 is fixedly provided on the inner wall of the wastewater pipe 300 at the connection point with the outer tube 410. The second sealing ring 310 is in sealing contact with the outer wall of the core tube 430 to ensure that the organic wastewater is fully filtered through the filter screen.

[0037] The organic wastewater heat recovery and cooling device provided by this utility model can not only regulate the flow rate of organic wastewater through the control and filtration components, but also filter and retain the flocculent or particulate matter carried in the organic wastewater, and can also easily clean up the retained flocculent or particulate matter, thereby realizing the regulation of the heat exchange efficiency of the heat exchanger.

[0038] As the core tube 430 moves to the right along the axis, the flocculent or particulate matter trapped on the filter screen is scraped off by the wastewater pipe 300 or the second sealing ring 310.

[0039] The driver components include:

[0040] A first connecting rod 510 and a second connecting rod 520 are connected. The first end of the first connecting rod 510 is hinged to the first end of the second connecting rod 520, and the second end of the first connecting rod 510 is hinged to the end plate 431. The hinge axes of the first connecting rod 510 and the second connecting rod 520 are parallel to each other and perpendicular to the axis of the wastewater pipe 300. Specifically, a hinge seat can be provided at the center of the end plate, and the first connecting rod 510 is hinged to the hinge seat.

[0041] A rotating shaft 530 passes through the second end of the second connecting rod 520 and is fixedly connected to the second connecting rod 520. The rotating shaft 530 is parallel to the hinge axis of the second connecting rod 520. Both ends of the rotating shaft 530 pass through the inner tube 420 and the outer tube 410 respectively and are rotatably and sealingly connected to the inner tube 420 and the outer tube 410.

[0042] The worm gear mechanism is located outside the outer tube 410. The worm 540 is fixedly sleeved on the end of the rotating shaft, and the end of the worm 550 is provided with a rotating handle 551.

[0043] When the position of the core tube 430 needs to be adjusted, rotating the worm gear 550 will drive the rotating shaft 530 to rotate, which in turn drives the second connecting rod 520 to rotate. The rotation of the second connecting rod 520 will pull the first end of the first connecting rod 510 to move, thereby driving the core tube 430 to move. When using a worm gear mechanism, the installation and sealing of the rotating shaft 530 with the inner tube 420 and the outer tube 410 are simple.

[0044] Specifically, the outer wall of the outer tube 410 is provided with a mounting box 500, and the turbine 540 and worm gear 550 mechanism are installed inside the mounting box 500.

[0045] Furthermore, a drain pipe 600 is connected to the bottom of the outer tube 410. The flocculent or particulate matter scraped off from the filter screen remains in the outer tube 410. After a certain period of operation, it can be cleaned out from the outer tube 410 and the drain pipe 600 using high-pressure water.
