Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment devices, and specifically, to a low-temperature-difference DTRO membrane treatment device. Background Technique

[0002] In the field of water treatment, reverse osmosis (RO) technology, especially the disk tube reverse osmosis (DTRO) membrane technology, has attracted much attention due to its high separation performance and wide application range. The DTRO membrane technology adopts a unique disk design. Through the stacking of multiple membrane elements, it realizes high flux, high anti-pollution ability and high stability, and is especially suitable for treating high-concentration and highly polluted water bodies.

[0003] There are many types of DTRO membrane treatment devices on the market, but most of the DTRO membrane treatment devices lack components that can cool or heat the sewage, which is not conducive to reducing the temperature difference. Due to the different environments of the treated sewage, such as when the temperature of the treated sewage is too high or too low, low temperature will cause the viscosity of water to increase, thereby increasing the resistance of water flow through the membrane element, reducing the membrane flux, and affecting the treatment effect. In addition, low temperature or high temperature may also affect the performance of the membrane material, such as reducing the mechanical strength and anti-pollution ability of the membrane, thereby affecting the treatment effect. In view of this, we propose a low-temperature-difference DTRO membrane treatment device. Content of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-4 , the present invention provides a technical solution: a low-temperature difference DTRO membrane treatment device, including a main body 1 of a disk tube reverse osmosis water treatment device and a sewage pipe 10 installed at the water inlet end of the main body 1 of the disk tube reverse osmosis water treatment device. A temperature sensor 2 is fixedly installed on the pipe body of the water outlet end of the sewage pipe 10, and the temperature sensor 2 is used for temperature detection operation;

[0028] Specifically, a temperature adjustment component 3 is arranged on the sewage pipe 10. The temperature adjustment component 3 includes a spiral heat exchange tube 30 arranged in the sewage pipe 10. The spiral heat exchange tube 30 is spiral, and the length of the spiral heat exchange tube 30 is 90 cm to 150 cm, which is used for heat exchange operation;

[0029] Specifically, the liquid inlet end pipe body of the spiral heat exchange pipe 30 passes through the sewage pipe 10 and is fixedly installed with a liquid inlet pipe 31. A temperature control valve 311 is fixedly installed on the liquid inlet pipe 31, and the temperature control valve 311 is used to control the liquid flow rate according to the actual temperature. The end of the liquid inlet pipe 31 is fixedly installed with a first three-way pipe 32. An oil inlet pipe 321 and a water inlet pipe 322 are respectively fixedly installed on the remaining two pipe bodies of the first three-way pipe 32. The liquid outlet end pipe body of the spiral heat exchange pipe 30 passes through the sewage pipe 10 and is fixedly installed with a liquid outlet pipe 33. The end of the liquid outlet pipe 33 is fixedly installed with a second three-way pipe 34. An oil outlet pipe 341 and a water outlet pipe 342 are respectively fixedly installed on the remaining two pipe bodies of the second three-way pipe 34. Three-way valves 35 are fixedly installed on both the first three-way pipe 32 and the second three-way pipe 34, so as to realize the operation of heating by introducing hot oil or cooling by introducing cold water as needed.

[0030] In this embodiment, two symmetrically arranged valves 12 are fixedly installed on the sewage pipe 10, and the temperature sensor 2 is located between the two valves 12. When replacing the temperature sensor 2, closing the valves 12 can prevent sewage from flowing out.

[0031] Specifically, a threaded pipe 11 is fixedly installed on the pipe body of the sewage pipe 10, and a threaded joint 23 is fixedly installed at the bottom end of the temperature sensor 2. The threaded joint 23 is threadedly connected to the threaded pipe 11, which is convenient for installing the temperature sensor 2.

[0032] Furthermore, a limit disk 20 is fixedly installed at the top of the threaded joint 23, and a sealing ring 22 is sleeved on the threaded joint 23. The limit disk 20 presses the sealing ring 22 against the upper surface of the threaded pipe 11, which is beneficial to improving the sealing effect.

[0033] In addition, a knob 21 is fixedly installed on the upper surface of the limit disk 20, and the cross section of the knob 21 is hexagonal, which makes it more labor-saving to use an external wrench to rotate the knob 21.

[0034] It should be noted that the inner diameters of the liquid inlet pipe 31, the spiral heat exchange pipe 30, and the liquid outlet pipe 33 are equal, which is used for stable fluid transportation operation.

[0035] It should be noted that a control host 4 is arranged on one side of the sewage pipe 10. The temperature sensor 2 and the temperature control valve 311 are electrically connected to the control host 4. The temperature sensor 2 detects the temperature. When the detected temperature exceeds or is lower than the threshold set in the control host 4, the control host 4 can control the temperature control valve 311 to work. After the temperature control valve 311 works, it can control the fluid passing amount. After the hot oil passing amount changes, the heating effect on the sewage will also change, so as to realize reducing or increasing the sewage temperature; when encountering relatively hot sewage, controlling the cold water passing amount can realize reducing the temperature of the hot sewage.

[0036] Finally, it should be noted that components such as the control host 4, temperature control valve 311, and temperature sensor 2 involved in the present utility model are all common standard components or components known to those skilled in the art. Their structures and principles can all be learned by those skilled in the art through technical manuals or by conventional experimental methods. At the idle place of the present device, all the above-mentioned electrical components, which refer to power components, electrical components, and the adapted controllers and power supplies, are connected by wires. The specific connection means should refer to the working principle of the present utility model, and the electrical connection is completed among the electrical components in the order of their working sequence. All the detailed connection means are well-known technologies in the art.

[0037] When the low-temperature difference DTRO membrane treatment device of the present utility model is in use, first, according to the type of sewage, it is judged whether the sewage is high-temperature sewage or low-temperature sewage. In the case of high-temperature sewage, the water inlet pipe 322 and the water outlet pipe 342 are connected to the external cooling water conveying device, and the three-way valve 35 is rotated until the liquid inlet pipe 31 is communicated with the water inlet pipe 322 and the liquid outlet pipe 33 is communicated with the water outlet pipe 342; if it is low-temperature sewage, the oil inlet pipe 321 and the oil outlet pipe 341 are connected to the external hot oil conveying device, and the three-way valve 35 is rotated until the oil inlet pipe 321 is communicated with the water inlet pipe 322 and the liquid outlet pipe 33 is communicated with the oil outlet pipe 341. After the hot oil or cooling water enters the spiral heat exchange tube 30, the sewage in the spiral heat exchange tube 30 can be heat-exchanged, so that the temperature difference between the sewage and the temperature of the membrane part in the main body 1 of the disk tube reverse osmosis water treatment device is reduced.

[0038] The above shows and describes the basic principle, main features, and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above-mentioned embodiments.
