Description

Technical Field

[0001] This utility model relates to the field of membrane separation device technology, specifically to an industrial condensate membrane separation and reuse device. Background Technology

[0002] Industrial condensate is liquid water formed when steam or high-temperature gases condense as their temperature decreases during industrial production. It is a byproduct of industrial thermal systems (such as boilers, steam heating, and heat exchangers). Industrial condensate is a valuable "secondary resource," and its recycling aligns with the requirements of a circular economy and green manufacturing. By optimizing system design and adopting efficient recycling technologies, enterprises can achieve multiple benefits, including water conservation, energy saving, and cost reduction, while also minimizing environmental impact. With the advancement of industrial energy conservation policies, condensate recycling will become an important means for industrial enterprises to enhance their competitiveness.

[0003] In the existing technology, the membrane separation device used for industrial condensate has low filtration efficiency and is not comprehensive enough, which affects the reuse effect of condensate. Moreover, since industrial condensate often contains oil, the existing membrane separation device cannot separate the oil in the condensate, which can easily contaminate downstream equipment when the condensate is reused. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an industrial condensate membrane separation and reuse device.

[0005] The technical solution of this utility model is as follows: an industrial condensate membrane separation and reuse device, including a box, an oil-water separation component and a membrane separation component disposed inside the box; the box includes a first box and a second box disposed at the bottom of the first box; a water inlet pipe is disposed at the top of the first box, a drain hole is disposed at the connection between the second box and the first box, and an inspection door and a drain pipe are respectively disposed on the outer side wall of the second box.

[0006] The oil-water separation component is located inside the first housing and is connected to the water inlet pipe. The oil-water separation component is used to separate the oil phase in industrial condensate.

[0007] The membrane separation assembly includes a flow collector shroud located at the top of the second chamber and communicating with the drain hole, a lifting screen plate slidably engaged with the bottom of the second chamber, and several membrane separators equidistantly distributed on the lifting screen plate and communicating with the flow collector shroud. Several docking sleeves are equidistantly distributed at the lower end of the flow collector shroud. The lifting screen plate is slidably engaged with the inner wall of the second chamber via a sliding rod, and a push spring is sleeved on the sliding rod to abut against the bottom surface of the lifting screen plate.

[0008] Furthermore, the membrane separator includes a separator housing, a screen tube fitted inside the separator housing, and a filter membrane fitted outside the screen tube; an end cap is threaded to the top of the separator housing, and a connecting pipe is provided on the end cap that can be movably engaged with the docking sleeve; several through holes are provided through the separator housing; the screen tube is movably engaged inside the separator housing.

[0009] Explanation: Industrial condensate enters the screen tube through the connecting pipe, is then filtered by the filter membrane, and is discharged from the separator shell. Finally, it is discharged through the drain pipe for reuse, while impurities in the condensate are filtered and intercepted by the filter membrane.

[0010] Furthermore, the oil-water separation assembly includes a centrifugal screen cylinder installed inside, a hydrophilic and oleophobic filter cloth sleeved inside the centrifugal screen cylinder, and a centrifugal motor installed at the bottom of the separation cylinder and providing power to the centrifugal screen cylinder; a movable cover is movably attached to the top of the first housing, and a water inlet pipe is installed on the movable cover; a waterproof outer shell located outside the centrifugal motor is installed inside the first housing.

[0011] Explanation: Industrial condensate first enters the centrifugal screen cylinder through the inlet pipe. Then, the centrifugal motor drives the centrifugal screen cylinder to rotate. Under the action of centrifugal force, the industrial condensate passes through the hydrophilic and oleophobic filter cloth and the centrifugal screen cylinder in sequence. Moreover, the oil in the condensate is adsorbed and intercepted by the hydrophilic and oleophobic filter cloth, thus achieving effective removal of oil from the condensate.

[0012] Furthermore, several push seats are slidably engaged at the bottom of the centrifuge screen, and each push seat is equipped with a limiting pressure plate that abuts against the inner wall of the hydrophilic and oleophobic filter cloth. A damping spring that abuts against the push seat is provided at the bottom of the centrifuge screen.

[0013] Note: Under the action of the damping spring, the pusher seat pushes the limiting pressure plate to always be close to the hydrophilic and oleophobic filter cloth, which prevents the hydrophilic and oleophobic filter cloth from falling off and shifting during the rotation of the centrifugal screen, thus improving the reliability of the oil-water separation component.

[0014] Furthermore, a release disc is rotatably engaged at the center of the bottom of the centrifugal mesh cylinder, and pull ropes connected to each push seat are provided on the outer wall of the release disc, and an operating lever is provided on the upper end face of the release disc;

[0015] Explanation: The release disc is rotated by the operating lever, which causes the push seats to move closer to each other under the pulling action of the pull rope. At this time, the limit pressure plates are disengaged from the hydrophilic and oleophobic filter cloth, thereby improving the convenience of replacing the hydrophilic and oleophobic filter cloth.

[0016] Furthermore, it also includes a heat exchange assembly disposed outside the first housing. The heat exchange assembly includes a heat exchange box disposed outside the first housing, a cold water pipe coiled inside the heat exchange box, and a working pipe disposed inside the cold water pipe. Both ends of the cold water pipe are respectively provided with a cold water inlet pipe and a cold water recovery pipe that penetrate the heat exchange box. Both ends of the working pipe are respectively connected to a medium inlet pipe and a medium discharge pipe that pass through the cold water pipe and the heat exchange box in sequence. The medium discharge pipe is connected to the water inlet pipe through a conduit.

[0017] Instructions: When in use, external clean water is introduced into the cold water pipe through the cold water inlet pipe, and industrial condensate is introduced into the working pipe through the medium inlet pipe. When the industrial condensate flows through the working pipe, it exchanges heat with the clean water in the cold water pipe, thereby recovering and utilizing the heat in the industrial condensate.

[0018] The working principle of this utility model is as follows:

[0019] In operation, external clean water is introduced into the cold water pipe through the cold water inlet pipe, while industrial condensate is introduced into the working pipe through the medium inlet pipe. As the industrial condensate flows through the working pipe, it exchanges heat with the clean water in the cold water pipe, recovering and utilizing the heat in the industrial condensate. After heat exchange, the industrial condensate enters the centrifugal screen cylinder through the inlet pipe. The centrifugal motor drives the centrifugal screen cylinder to rotate, and under the action of centrifugal force, the industrial condensate passes through the hydrophilic and oleophobic filter cloth and the centrifugal screen cylinder in sequence. Moreover, the oil in the condensate is adsorbed and intercepted by the hydrophilic and oleophobic filter cloth. After oil removal, the condensate enters the collector hood through the drain hole and enters the corresponding screen tube through the connecting pipe. Then, it is filtered by the filter membrane and discharged from the separator shell, and finally discharged for reuse through the drain pipe. The impurities in the condensate are filtered and intercepted by the filter membrane.

[0020] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0021] First, the structure of this utility model is reasonable. By movably setting the membrane separator inside the second housing, it is convenient to replace and clean the filter membrane. Setting multiple membrane separators can improve the filtration efficiency of industrial condensate and reduce the risk of equipment blockage and shutdown.

[0022] Secondly, this utility model uses hydrophilic and oleophobic filter cloth to separate oil from industrial condensate, which can prevent pollution of downstream equipment when industrial condensate is reused, and can also prevent pollution of rivers and soil when industrial condensate is discharged, thus improving the safety of industrial condensate reuse.

[0023] Third, this utility model utilizes heat exchange components to recover and reuse heat from industrial condensate, thereby improving the economic benefits of industrial condensate reuse. Attached Figure Description
