Abstract
Description
Technical Field
[0001] This utility model relates to the field of reverse osmosis equipment testing technology, and in particular to an environmental protection equipment testing device. Background Technology
[0002] Environmental protection equipment refers to mechanical equipment or devices specifically designed to reduce pollution, protect the environment, and improve environmental quality, including reverse osmosis equipment. After long-term operation, various impurities carried by wastewater will adhere to the reverse osmosis membrane, thereby affecting the filtration performance of the reverse osmosis membrane. Therefore, during use, pressure gauges need to be installed at the inlet and concentrate ends of the membrane module to monitor the pressure difference change to detect the degree of fouling of the membrane module and thus determine whether cleaning is required.
[0003] However, existing detection methods are lagging, only able to detect abnormalities after pollution reaches a certain level, and cannot provide timely warnings;
[0004] Meanwhile, existing testing equipment cannot detect what kind of fouling the membrane module is affected by. It is necessary to disassemble the membrane module for inspection in order to accurately determine the type of fouling. Only then can the corresponding flushing water be used for cleaning, which makes the testing process cumbersome. Therefore, in actual cleaning, chemical cleaning is usually carried out based on experience to guess the type of fouling. If the cleaning effect is not good, the weight of the cleaning agent is changed and the cleaning is repeated until the pressure difference at both ends returns to normal. This results in a large consumption of chemical agents and a large discharge of chemical cleaning wastewater.
[0005] Therefore, an environmental protection equipment testing device is proposed to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to solve the problems of lag in the testing of reverse osmosis equipment in the prior art, the inability to detect the type of contamination of the membrane module, the large amount of reagent consumption and chemical cleaning wastewater discharge, and to propose an environmentally friendly equipment testing device.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] An environmental protection equipment testing device includes a reverse osmosis equipment body and a water supply pipeline. The water supply pipeline is located at the input end of the reverse osmosis equipment body. A branch pipe is provided on the outer wall of the water supply pipeline. A three-way solenoid valve is provided at the bottom of the branch pipe. A test pipeline is provided on one side of the three-way solenoid valve. A testing component is provided on the other side of the three-way solenoid valve.
[0009] The detection assembly includes a housing and a fixed cover, with a small filter element disposed between the housing and the fixed cover.
[0010] Preferably, a pH sensor is fixedly installed on the outer wall of the test pipe.
[0011] Preferably, a water inlet pipe is fixedly installed in the center inside the fixed cover, the input end of the water inlet pipe is fixedly connected to a three-way solenoid valve, and the outer wall of the water inlet pipe passes through the fixed cover and is connected to a front-end water pressure sensor.
[0012] Preferably, the housing is threadedly connected to the fixed cover, a sealing ring is fixedly connected to one end of the housing near the fixed cover, a water outlet pipe is fixedly installed at the center of the end of the housing away from the fixed cover, and a concentrated water pipe communicating with the housing is provided at the bottom of the water outlet pipe.
[0013] Preferably, an end water pressure sensor is fixedly connected to the outer wall of the concentrate pipe.
[0014] Preferably, one end of the small filter element is threaded to the input end of the concentrate pipe, and the other end of the small filter element is not connected to the inlet pipe.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model, by setting up a branch pipe, a shell and a fixing cover, makes the working environment of the small filter element similar to that of the reverse osmosis equipment body. Because the volume of the small filter element is much smaller than that of the membrane module in the reverse osmosis equipment body, it can experience pressure difference abnormality before the reverse osmosis equipment body after being contaminated, thereby achieving the function of preventing serious contamination of the reverse osmosis equipment.
[0017] 2. This utility model, through the combined use of a pH sensor, a front-end water pressure sensor, and a rear-end water pressure sensor, can send data to an industrial control computer for analysis. If the pressure difference recovers after acid washing, it is recorded as inorganic contamination by the industrial control computer; if the pressure difference recovers after alkaline washing, it is recorded as organic contamination; if the pressure difference does not recover after either acid or alkaline washing, it is recorded as biofilm contamination. This realizes the function of cleaning response analysis, and can detect the type of contamination and perform targeted cleaning through the elimination method without disassembling the reverse osmosis equipment body, saving various cleaning agents and thus reducing pollutant emissions caused by chemical cleaning.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1-5 An environmental protection equipment testing device includes a reverse osmosis equipment body 1 and a water supply pipe 2. The water supply pipe 2 is located at the input end of the reverse osmosis equipment body 1. A branch pipe 3 is provided on the outer side wall of the water supply pipe 2. A three-way solenoid valve 4 is provided at the bottom of the branch pipe 3. A test pipe 5 is provided on one side of the three-way solenoid valve 4. A testing component is provided on the other side of the three-way solenoid valve 4.
[0026] The detection assembly includes a housing 6 and a fixed cover 7, with a small filter element 8 disposed between the housing 6 and the fixed cover 7.
[0027] A further advantage of the above is that by setting up the branch pipe 3, the housing 6 and the fixed cover 7, the working environment of the small filter element 8 is similar to that of the reverse osmosis equipment body 1. Because the volume of the small filter element 8 is much smaller than that of the membrane module in the reverse osmosis equipment body 1, it can experience pressure difference abnormality before the reverse osmosis equipment body 1 after being fouled, thereby achieving the effect of preventing serious fouling of the reverse osmosis equipment.
[0028] Furthermore, a pH sensor 9 is fixedly installed on the outer wall of the test pipe 5 to detect the acidity or alkalinity of the cleaning water.
[0029] Furthermore, a water inlet pipe 10 is fixedly installed in the center of the fixed cover 7. The input end of the water inlet pipe 10 is fixedly connected to the three-way solenoid valve 4. The outer wall of the water inlet pipe 10 passes through the fixed cover 7 and is connected to the front water pressure sensor 11. The housing 6 is threadedly connected to the fixed cover 7. A sealing ring 12 is fixedly connected to the end of the housing 6 near the fixed cover 7. A water outlet pipe 13 is fixedly installed in the center of the end of the housing 6 away from the fixed cover 7. A concentrated water pipe 14 is provided at the bottom of the water outlet pipe 13 and is connected to the housing 6. An end water pressure sensor 15 is fixedly connected to the outer wall of the concentrated water pipe 14.
[0030] A further advantage of the above approach is that, through the combined use of pH sensor 9, front-end water pressure sensor 11, and end-end water pressure sensor 15, data can be sent to an industrial control computer for analysis. If the pressure difference between the two ends recovers after acid washing, it is recorded as inorganic contamination by the industrial control computer; if the pressure difference recovers after alkaline washing, it is recorded as organic contamination; and if the pressure difference does not recover after either acid or alkaline washing, it is recorded as biofilm contamination, thus realizing the function of cleaning response analysis.
[0031] It should be noted that industrial control computers are existing technology and will not be discussed further.
[0032] Furthermore, one end of the small filter element 8 is threaded to the input end of the concentrate pipe 14, while the other end of the small filter element 8 is not connected to the inlet pipe 10.
[0033] When this utility model is in use, as sewage enters the reverse osmosis equipment body 1 through the water supply pipe 2, some sewage flows out from the branch pipe 3 and enters the inlet pipe 10 through the three-way solenoid valve 4. During this process, the pressure at the inlet end is collected by the front-end water pressure sensor 11. After flowing out of the inlet pipe 10, it enters the input end of the small filter element 8. After the sewage is filtered by the small filter element 8, the purified water flows out from the output end of the small filter element 8 into the outlet pipe 13 and is discharged. The remaining concentrated water flows into the concentrate pipe 14 and is discharged. The pressure data at the concentrate end is collected by the end water pressure sensor 15. Because the volume of the small filter element 8 is much smaller than the membrane module in the reverse osmosis equipment body 1, it can experience pressure difference abnormalities before the reverse osmosis equipment body 1 after being fouled, thus achieving the function of preventing serious fouling of the reverse osmosis equipment.
[0034] When the pressure difference between the front-end water pressure sensor 11 and the end water pressure sensor 15 becomes abnormal, the industrial control computer will issue an early warning. At this time, the operator will adjust the detergent according to their work experience and perform the first rinse.
[0035] Taking acid washing as an example, after the industrial control computer executes the detection program, the three-way solenoid valve 4 is adjusted to connect the test pipe 5, the three-way solenoid valve 4, and the inlet pipe 10. Then, as the acid washing water enters from the test pipe 5, the pH sensor 9 records the acid and alkalinity of the washing solution and sends it to the industrial control computer to avoid errors in the acid-alkalinity adjustment of the washing solution caused by human error. After acid washing is completed, the industrial control computer analyzes the data from the pH sensor 9, the front-end water pressure sensor 11, and the end water pressure sensor 15 to determine the cleaning result. If the pressure difference between the two ends recovers after acid washing, it is recorded as inorganic contamination by the industrial control computer. If the pressure difference recovers after alkaline washing, it is recorded as organic contamination. If the pressure difference does not recover after either acid washing or alkaline washing, it is recorded as biofilm contamination. This realizes the function of cleaning response analysis and can detect the type of contamination by elimination without disassembling the reverse osmosis equipment body 1.
[0036] After identifying the type of contamination, a targeted cleaning agent was used to perform a targeted chemical cleaning on the reverse osmosis equipment body 1, reducing the consumption of cleaning agents and the discharge of chemical cleaning wastewater.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
