Description

Technical Field

[0001] The utility model belongs to the technical field of reverse osmosis membrane detection devices, and specifically relates to a reverse osmosis membrane failure accurate detection device. Background Art

[0002] Most of the water systems in metallurgical systems need to filter water. Reverse osmosis equipment is a commonly used filtration equipment. The reverse osmosis equipment used on site is as follows: Figure 3 As shown, it mainly includes reverse osmosis membrane tubes. Each set of reverse osmosis equipment contains five groups of membrane tubes. There are 5 reverse osmosis membranes in each membrane tube. There is an inlet valve at the bottom of the reverse osmosis membrane tube, an outlet valve at the end of the reverse osmosis membrane tube, and a plug is arranged on the other side of each group of membrane tubes.

[0003] During the daily operation of the reverse osmosis equipment, if it fails and cannot achieve the filtering effect, it will first be cleaned by acid washing, alkali washing and other processes, and then the filtering effect will be restored and it can continue to be used. However, if the reverse osmosis membrane fails physically and cannot be restored by acid washing, alkali washing and other processes, it needs to be replaced to restore the normal operation of the reverse osmosis equipment.

[0004] according to Figure 3 Once the structure shown and the current technical specifications of the reverse osmosis membrane fail, the only means of detection is to take water samples through the outlet valve of each membrane tube, and determine which membrane tube has failed by detecting the conductivity value of the water sample. After making a judgment, the five reverse osmosis membranes in the entire membrane tube are replaced to restore the function of the anti-permeation device.

[0005] The disadvantage of the existing equipment structure is that it can only diagnose which membrane tube has an abnormality by sampling and testing each membrane tube valve, but cannot accurately determine which reverse osmosis membrane in the membrane tube has an abnormality, resulting in increased equipment maintenance costs and waste of resources. Therefore, a reverse osmosis membrane failure accurate detection device is proposed. Utility Model Content

[0006] The utility model aims to provide a device for accurately detecting failure of a reverse osmosis membrane, which has the function of accurately detecting failure of a reverse osmosis membrane, and solves the problem that the prior art can only diagnose which specific membrane tube has an abnormality through sampling and detection of each membrane tube valve, but cannot accurately determine which reverse osmosis membrane in the membrane tube has an abnormality, resulting in increased equipment maintenance costs and waste of resources.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is that the utility model provides a precise detection device for reverse osmosis membrane failure, including a PU tube, a valve is arranged at the front end of the PU tube, a wire plug is sleeved on the PU tube, the PU tube is inserted into a reverse osmosis membrane tube, and a reverse osmosis membrane is arranged in the reverse osmosis membrane tube.

[0008] Preferably, the length of the PU tube is greater than the length of the reverse osmosis membrane tube.

[0009] Preferably, the plug is in the shape of a circular cylinder, and the diameter of the plug is the same as the diameter of the inner wall of the reverse osmosis membrane tube.

[0010] Preferably, the thread plug is fixed on the PU tube by means of sealant.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. The utility model can accurately determine the failure status of each reverse osmosis membrane in each membrane tube, effectively guide maintenance and repair, save costs and reduce energy consumption;

[0013] 2. The utility model has the function of accurately detecting reverse osmosis membrane failure, which solves the problem that the prior art can only diagnose which specific membrane tube has an abnormality through sampling and detection of each membrane tube valve, but cannot accurately determine which reverse osmosis membrane in the membrane tube has an abnormality, resulting in increased equipment maintenance costs and waste of resources.

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] Embodiment 1, as Figure 1-2 As shown, a reverse osmosis membrane 6 failure accurate detection device includes a PU tube 1. The PU tube 1 has good flexibility and good corrosion resistance, is suitable for the acid and alkali washing process of the reverse osmosis system, and has a long service life. The front end of the PU tube 1 is provided with a valve 2, which is used to control the water flow in the PU tube 1, facilitates sampling and detection, can accurately control the opening and closing of the water flow, ensures the accuracy of sampling, is convenient to use, and is easy to operate and maintain.

[0022] The PU tube 1 is sleeved with a thread plug 3, which is installed on the PU tube 1 and used to fix the PU tube 1. The PU tube 1 is inserted into the reverse osmosis membrane tube 5, and the thread plug 3 is fixed, so that the PU tube 1 will not loosen or shift during use, and can maintain a good sealing and fixing effect for a long time. The reverse osmosis membrane tube 5 is provided with a reverse osmosis membrane 6, which is a container for installing the reverse osmosis membrane 6 and provides a channel for water to flow through the reverse osmosis membrane 6. The reverse osmosis membrane 6 is a core filter element, which removes impurities and dissolved salts in the water through the reverse osmosis process, can efficiently remove impurities in the water, ensure pure water quality, have a long service life, and can maintain a good filtering effect for a long time.

[0023] The following is a detailed description of the design of the above key components:

[0024] The length of the PU tube 1 is greater than that of the reverse osmosis membrane tube 5, ensuring that the PU tube 1 can be inserted into the reverse osmosis membrane tube 5, while leaving a certain margin so that the reverse osmosis membrane 6 at different positions can be detected by adjusting the insertion length, so that the degree is adjustable and different depths can be inserted as needed to obtain water samples behind the reverse osmosis membrane 6 at different positions.

[0025] The thread plug 3 is in the shape of a circular cylinder, and the diameter of the thread plug 3 is the same as the inner wall diameter of the reverse osmosis membrane tube 5, ensuring a tight fit without water leakage.

[0026] The thread plug 3 is fixed on the PU tube 1 by means of a sealant 4, which ensures the sealing effect of the connection between the thread plug 3 and the PU tube to prevent water leakage. At the same time, the sealant 4 with good chemical corrosion resistance is selected to adapt to the working environment of the reverse osmosis system and ensure the long-term stability of the sealing effect.

[0027] The length of the PU tube 1 needs to be greater than the length of the reverse osmosis membrane tube 5. The PU tube 1 is inserted into the reverse osmosis membrane tube 5. The screw plug 3 is set at the front end of the reverse osmosis membrane tube 5. By controlling the insertion length of the PU tube 1, the water sample filtered by the reverse osmosis membrane 6 at different positions of the reverse osmosis membrane tube 5 is led out through the valve 2 to control the water sample in and out. The screw plug 3 mainly replaces the structure of the reverse osmosis membrane 6 Figure 3 The plug in the middle, the thread plug 3 is used to plug the reverse osmosis membrane tube 5 to prevent water leakage, ensuring that the installation is firm, reliable and leak-free.

[0028] Fix the wire plug 3 at different positions of different PU tubes 1 as needed, replace the PU tube 1 according to the depth of the reverse osmosis membrane tube 5, and after detecting at the end of the reverse osmosis membrane tube 5, if there is abnormal water quality, remove the reverse osmosis membrane 6 from the back to the front and use the elimination method to detect the remaining reverse osmosis membrane 6.
