TECHNICAL FIELD

[0001] The utility model relates to membrane module technical field, especially a kind of high temperature resistant membrane module. BACKGROUND

[0002] The statements in this part are only provided with the background technology related to the utility model disclosed, and do not necessarily constitute prior art.

[0003] The existing organic membrane filtering assembly can withstand the highest feed temperature of 45 DEG C, and when treating certain high-temperature liquid in fields such as plant extraction, beverage concentration and powder washing, the liquid needs to be cooled, which wastes production efficiency and time and increases investment. Most high-temperature liquid treatment adopts inorganic membrane process, which has high investment and high energy consumption. The organic membrane assembly with nominal high-temperature resistance on the market has different expansion and shrinkage coefficients of epoxy resin fillers and membrane shells at both ends, which can cause cracks in the epoxy resin shell, and further cause water production side leakage.

[0012] In the technical solution, the material of the membrane shell and the membrane cover is glass steel or chlorinated polyvinyl chloride or stainless steel.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. High-temperature self-adaptive sealing, which can realize dynamic compensation: when high temperature causes a small gap between the heat-resistant resin and the membrane shell, the system operating pressure automatically compacts the sealing ring, fills the gap in real time, and avoids the problem of failure of traditional static sealing due to thermal deformation.

[0015] 2. Double sealing protection: the heat-resistant resin of the main sealing layer serves as the first barrier, and forms a rigid support after high-temperature curing; the elastic sealing ring of the secondary sealing layer is deformed under pressure at high temperature, forming a second flexible sealing, and cooperating to block the bidirectional permeation of the material liquid (the water production side and the inner wall of the membrane shell).

[0016] 3. Anti-thermal stress deformation: the difference in expansion coefficients between the heat-resistant resin and the metal membrane shell is absorbed by the elastic deformation of the sealing ring, avoiding tearing or permanent deformation of the sealing structure caused by temperature difference.

[0017] 4. Precise blocking of leakage path: transverse sealing, the design of the sealing ring embedded in the groove blocks the longitudinal leakage channel of the material liquid along the inner wall of the membrane shell; radial sealing, the high-temperature-resistant sealing ring and the high-temperature-resistant spring after compaction fill the annular gap between the membrane core, preventing the material liquid from penetrating laterally to the water production side.

[0018] 5. Long-term stability: the materials are selected from silicone rubber, fluororubber, hydrogenated nitrile rubber, chlorosulfonated polyethylene rubber, chlorohydrin rubber, acrylate and borosilicon rubber, and the sealing ring and the high-temperature-resistant sealing ring do not creep and relax under continuous high-pressure working conditions, ensuring that the sealing performance does not degrade during long-term operation.

[0019] 6. Improved high-temperature material liquid treatment capacity: compared with ordinary organic membrane products, the product can treat high-temperature material liquid above 100℃.

[0020] 7. Enhanced sealing effect: high temperature or causes the heat-resistant resin to separate from the membrane shell and produce a small gap, at which time the sealing ring is in a compacted state during system operation, which can block the material liquid from leaking into the water production side from the gap, achieving the effect of sealing.

[0021] The utility model discloses a kind of high-temperature-resistant membrane assemblies, solve the problem of water production side leakage when handling high-temperature liquid, realize high-temperature self-adaptive sealing, can realize dynamic compensation, use double sealing protection, with heat stress deformation resistance, and realize the accurate blocking of leakage path, and service life is longer.
