Description

Technical Field

[0001] The present application relates to the technical field of reverse osmosis membrane cleaning, and in particular to an integrated reverse osmosis membrane offline cleaning and testing device. Background Art

[0002] Most reverse osmosis membranes in the prior art are cleaned online, meaning the equipment uses its own cleaning system to clean the membrane. The online cleaning process involves isolating the membrane module to be cleaned from other equipment and using the cleaning system to pump cleaning fluid into the module and out the concentrated water outlet.

[0003] This cleaning method typically cleans the entire membrane module simultaneously. Typically, a membrane module consists of multiple segments, each with several membrane shells connected in parallel. Each shell houses 6 to 8 reverse osmosis membranes connected in series. Conventional online cleaning methods typically circulate and clean the reverse osmosis membranes within multiple shells simultaneously. This large-scale, simultaneous cleaning method fails to ensure adequate cleaning of each reverse osmosis membrane, resulting in low cleaning efficiency. Utility Model Content

[0057] Conventional online cleaning methods usually circulate and clean the reverse osmosis membranes in multiple membrane shells at the same time. This large-scale synchronous cleaning method cannot ensure that each reverse osmosis membrane has a good cleaning effect, and the cleaning efficiency is low.

[0058] In order to solve the technical problem that online cleaning cannot achieve good cleaning effect on each reverse osmosis membrane, such as Figure 1 and Figure 2 As shown, the present application provides an integrated reverse osmosis membrane offline cleaning and testing device 100, including a frame 140 and a liquid storage component 110, a dosing component 120 and a cleaning component 130 fixed on the frame 140, the cleaning liquid circulates between the liquid storage component 110, the dosing component 120 and the cleaning component 130, the cleaning component 130 includes a plurality of independent cleaning units 131, and the cleaning unit 131 is used to clean a single reverse osmosis membrane.

[0059] Among them, by arranging the liquid storage component 110, the dosing component 120 and the cleaning component 130 on the frame 140, the integrated reverse osmosis membrane offline cleaning and testing device 100 has stronger functionality and improved practicality.

[0060] Furthermore, by allowing the cleaning liquid to circulate between the liquid storage component 110, the dosing component 120 and the cleaning component 130, the overall cleaning effect of the cleaning component 130 is improved and the amount of cleaning agent and water used is reduced.

[0061] Furthermore, by providing a plurality of independent cleaning units 131, each cleaning unit 131 cleans each reverse osmosis membrane separately, so that each reverse osmosis membrane in the reverse osmosis membrane group is fully cleaned, thereby improving the cleaning effect of the reverse osmosis membrane and increasing the cleaning efficiency.

[0062] Furthermore, in the embodiments of the present application, Figure 1 and Figure 2 As shown, the integrated reverse osmosis membrane offline cleaning and testing device 100 includes a water inlet pipe 150, which connects the dosing component 120 and the cleaning component 130. In this way, when the cleaning liquid flows out of the liquid storage component 110, it passes through the dosing component 120, is mixed with the cleaning agent in the cleaning liquid, and then flows into the cleaning component 130 to clean the reverse osmosis membrane.

[0063] The water inlet pipe 150 includes a main water inlet pipe 151 and multiple branch water inlet pipes 152. The water inlet end of each cleaning unit 131 is connected to the main water inlet pipe 151 through the branch water inlet pipe 152. The main water inlet pipe 151 and the branch water inlet pipe 152 are detachably connected, and the branch water inlet pipes 152 are detachably connected to each other.

[0064] By providing a detachable connection between the main water inlet pipe 151 and the branch water inlet pipe 152, and a detachable connection between the branch water inlet pipes 152, the disassembly and assembly efficiency of the device can be improved, the transportation and storage of the device can be facilitated, and it is also easy to disassemble the integrated reverse osmosis membrane offline cleaning and testing device 100 and then transport it to the factory for reassembly to perform offline cleaning of the reverse osmosis membrane.

[0065] Exemplarily, the pipelines are detachably connected by a double union connection or a quick connector snap connection.

[0066] Furthermore, in the embodiments of the present application, Figure 1 and Figure 2 As shown, the integrated reverse osmosis membrane offline cleaning and testing device 100 also includes multiple flow monitoring components 160 and multiple concentration monitoring components (not shown). Each cleaning unit 131 is provided with a concentrate inlet (not shown) and a production water inlet (not shown). The concentrate inlet is provided with a flow monitoring component 160 and a concentration monitoring component, and the production water inlet is provided with a flow monitoring component 160 and a concentration monitoring component.

[0067] The flow monitoring component 160 is a pressure gauge or a flow meter, which facilitates reasonable adjustment of the recovery rate of the cleaning unit 131 during cleaning and testing, and facilitates analysis and evaluation of the cleaning effect of the cleaning unit 131.

[0068] Specifically, the recovery rate of a single cleaning unit 131 = product flow rate / inlet flow rate. Adjusting the concentrate valve opening adjusts the concentrate flow rate and pressure, thereby adjusting the recovery rate of a single cleaning unit 131. Furthermore, reverse osmosis membranes exhibit varying desalination rates at varying pressures and recovery rates, requiring data analysis during cleaning tests.

[0069] By providing the flow monitoring element 160 , it is possible to determine whether there is enough cleaning liquid in each cleaning unit 131 to fully clean the reverse osmosis membrane, thereby improving the cleaning effect.

[0070] By providing a concentration monitoring component, after the reverse osmosis membrane is cleaned, a test agent can be introduced into the cleaning unit 131 . By monitoring the concentration of the test agent, it can be determined whether the reverse osmosis membrane is clean.

[0071] Specifically, the effectiveness of chemical cleaning is determined by measuring the salt rejection rate of the reverse osmosis membrane. Salt rejection rate = (inlet TDS - product TDS) / inlet TDS (total dissolved solids). Good cleaning results are indicated by: 1. A decrease in inlet pressure while maintaining a constant inlet flow rate and recovery rate to the reverse osmosis membrane; 2. A decrease in product TDS before and after cleaning while maintaining a constant inlet flow rate and recovery rate to the reverse osmosis membrane.

[0072] Furthermore, in the embodiments of the present application, Figure 1 and Figure 2 As shown, the integrated reverse osmosis membrane offline cleaning and testing device 100 also includes a mutually independent concentrated water outlet pipeline 170 and a produced water outlet pipeline 180. The concentrated water outlet pipeline 170 connects the cleaning component 130 and the liquid storage component 110 to allow the cleaning liquid after the reverse osmosis membrane is cleaned to flow out.

[0073] The concentrate outlet pipeline 170 includes a main concentrate outlet pipe 171 and multiple concentrate dispensing pipes 172. The concentrate outlet of each cleaning unit 131 is connected to the main concentrate outlet pipe 171 via a concentrate dispensing pipe 172. The main concentrate outlet pipe 171 and the concentrate dispensing pipes 172 are detachably connected, and the individual concentrate dispensing pipes 172 are detachably connected to each other.

[0074] By making the concentrated water main outlet pipe 171 and the concentrated water discharging pipe 172 detachably connected, and the concentrated water discharging pipes 172 detachably connected, the disassembly and assembly efficiency of the device can be improved, and the transportation and storage of the device can be facilitated. It is also easy to disassemble the integrated reverse osmosis membrane offline cleaning and testing device 100 and then transport it to the factory for reassembly to perform offline cleaning of the reverse osmosis membrane.

[0075] Exemplarily, the pipelines are detachably connected by a double union connection or a quick connector snap connection.

[0076] Furthermore, in the embodiments of the present application, Figure 1 and Figure 2 As shown, the produced water outlet pipe 180 connects the cleaning assembly 130 and the liquid storage assembly 110 , and the water inlet pipe 150 connects the dosing assembly 120 and the cleaning assembly 130 , so that the cleaning liquid circulates among the liquid storage assembly 110 , the dosing assembly 120 and the cleaning assembly 130 .

[0077] The produced water outlet pipeline 180 includes a main produced water outlet pipe 181 and multiple produced water dispensing pipes 182. The water outlet of each cleaning unit 131 is connected to the main produced water outlet pipe 181 via the produced water dispensing pipe 182. The main produced water outlet pipe 181 and the produced water dispensing pipe 182 are detachably connected, and the individual produced water dispensing pipes 182 are detachably connected to each other.

[0078] By making the main water outlet pipe 181 and the water outlet pipe 182 detachably connected, and the water outlet pipes 182 detachably connected, the efficiency of disassembly and assembly of the device can be improved, and the transportation and storage of the device can be facilitated. It is also easy to disassemble the integrated reverse osmosis membrane offline cleaning and testing device 100 and then transport it to the factory for reassembly to perform offline cleaning of the reverse osmosis membrane.

[0079] Exemplarily, the pipelines are detachably connected by a double union connection or a quick connector snap connection.

[0080] Furthermore, in the embodiments of the present application, Figure 1 and Figure 2 As shown, the device further includes a liquid storage drain line (not shown) and a cleaning liquid drain line (not shown).

[0081] The liquid storage and emptying pipeline is connected to the liquid storage component 110, and can empty the cleaning liquid in the liquid storage container 111 to prevent contamination of the cleaning liquid for the next cleaning.

[0082] Each cleaning unit 131 is communicated with a cleaning liquid draining pipeline, so that the cleaning liquid in the cleaning unit 131 can be drained to prevent contamination of the cleaning liquid for the next cleaning.

[0083] Furthermore, in the embodiment of the present application, the cleaning unit 131 is provided with a liquid inlet valve (not shown) and a liquid outlet valve (not shown).

[0084] Among them, the liquid inlet valve is used to control the flow of cleaning liquid into the cleaning unit 131; the liquid outlet valve is used to control the flow of cleaning liquid into at least one of the cleaning liquid emptying pipeline, the concentrated water outlet pipeline 170 and the produced water outlet pipeline 180. In this way, it is convenient to select the cleaning liquid to be discharged into the cleaning liquid emptying pipeline, the concentrated water outlet pipeline 170 and the produced water outlet pipeline 180 according to the cleaning progress of the reverse osmosis membrane.

[0085] For example, during the cleaning process of the reverse osmosis membrane, the cleaning liquid can be discharged into the concentrated water outlet pipeline 170 or the produced water outlet pipeline 180, so that the cleaning liquid circulates through the dosing component 120 and the liquid storage component 110, which can improve the utilization rate of water and cleaning agents, and can also enable the reverse osmosis membrane to be cleaned repeatedly and accelerate the cleaning speed.

[0086] For example, after the cleaning of the reverse osmosis membrane is completed, the cleaning liquid can be discharged into the cleaning liquid emptying pipeline, and the waste liquid can be discharged in batches to prevent contamination of the cleaning liquid for the next cleaning.

[0087] In addition, by setting a liquid inlet valve and a liquid outlet valve and jointly controlling the opening and closing of the liquid inlet valve and the liquid outlet valve, the cleaning liquid can enter and stay in the cleaning unit 131 to soak and fully clean the reverse osmosis membrane. When the cleaning is completed, the cleaning liquid is discharged from the cleaning unit 131 in time.

[0088] Furthermore, in the embodiments of the present application, Figure 1 and Figure 2 As shown, the medicated assembly 120 includes a medicated component 121 , a temperature control unit 122 , a circulation pump 123 and a filter 124 .

[0089] The dispensing component 121 is connected to the liquid storage component 110 and is used to add cleaning agents to the cleaning liquid.

[0090] Temperature control unit 122 is used to heat the cleaning agent to a preset temperature and monitor the temperature of the cleaning solution in real time. By providing a temperature control component, exemplarily configured with a heater and a temperature detector, real-time monitoring of the cleaning tank and pipeline temperatures is achieved, ensuring that the cleaning solution is heated to the set temperature, thereby improving the cleaning effect of the reverse osmosis membrane.

[0091] Circulation pump 123 connects dispensing assembly 121 with filter element 124, which is in turn connected to main water inlet pipe 151. Circulation pump 123 allows cleaning fluid to circulate between liquid storage assembly 110, dosing assembly 120, and cleaning assembly 130. Filter element 124 removes impurities from the cleaning fluid, improving cleaning efficiency and results.

[0092] Furthermore, in the embodiments of the present application, Figure 1 and Figure 2 As shown, the liquid storage assembly 110 includes a liquid storage container 111 and a high-pressure variable frequency pump (not shown).

[0093] The main concentrated water outlet pipe 171 and the main produced water outlet pipe 181 are connected to the liquid storage container 111. The concentrated water outlet pipe 171 and the produced water outlet pipe 181 are connected and empty into the liquid storage container 111, so that the cleaning liquid circulates and cleans, reducing the consumption of cleaning chemicals during the cleaning process. If the pH of the cleaning liquid changes during the circulation process, the cleaning chemicals need to be replenished to maintain the cleaning liquid concentration. If the cleaning liquid is too dirty, it is emptied and refilled.

[0094] The water outlet end of the liquid storage container 111 is funnel-shaped, which can facilitate the connection between the liquid storage container 111 and the liquid storage and emptying pipeline, and can also speed up the discharge of waste liquid.

[0095] The high-pressure variable frequency pump is used to control the water inflow of the liquid storage container 111 and the internal solution pressure.

[0096] Furthermore, in the embodiments of the present application, Figure 1 and Figure 2 As shown, a plurality of rollers 141 are provided at the bottom of the frame 140 to facilitate the movement of the integrated reverse osmosis membrane offline cleaning and testing device 100 .

[0097] The working process of the integrated reverse osmosis membrane offline cleaning and testing device 100 is as follows:

[0098] The integrated reverse osmosis membrane offline cleaning and testing device 100 is pushed to the work site using the roller 141 and assembled;

[0099] Remove the reverse osmosis membrane from the reverse osmosis membrane group and install it into the cleaning unit 131;

[0100] The temperature control unit 122 heats the cleaning liquid in the pipeline, and the cleaning liquid enters the main water inlet pipe 151 through the circulation pump 123 and the filter element 124;

[0101] The water is then transported to each cleaning unit 131 through the branch water inlet pipe 152, and the cleaning liquid is repeatedly circulated to clean the reverse osmosis membrane;

[0102] During the cleaning process, check the flow monitoring unit 160 of each cleaning unit 131 and adjust the liquid inlet valve and liquid outlet valve accordingly to ensure that the reverse osmosis membrane is fully cleaned;

[0103] After cleaning is completed, open the liquid outlet valve to allow the waste liquid to flow out from the liquid storage drain pipe and the cleaning liquid drain pipe;

[0104] The cleaned reverse osmosis membrane is moved out of the cleaning unit 131 and the next batch of reverse osmosis membranes are cleaned. Alternatively, the main water inlet pipe 151, branch water inlet pipe 152, concentrated water main outlet pipe 171, concentrated water disbursement pipe 172, produced water main outlet pipe 181 and produced water disbursement pipe 182 of the integrated reverse osmosis membrane offline cleaning and testing device 100 are removed and stored and moved to the next work location.

[0105] Please also refer to Figures 1 to 2 According to one or more embodiments of the present application, the present application utilizes a frame 140 to fixedly integrate the liquid storage component 110, the dosing component 120 and the cleaning component 130.

[0106] The frame 140 is provided with rollers 141 for easy transportation;

[0107] Each main pipe and the corresponding branch pipe are connected in a detachable manner through a double union connection or a quick connector snap connection, which is easy to disassemble and assemble;

[0108] The cleaning unit 131 is provided with a concentrated water inlet and a produced water inlet, and a flow monitoring component 160 is provided at the concentrated water inlet and the produced water inlet, so that the water output data can be sampled and monitored at any time;

[0109] The dosing assembly 120 is equipped with a temperature control unit 122 to heat the cleaning liquid to improve the cleaning effect;

[0110] The bottom of the liquid outlet container is set to a funnel shape to facilitate the connection between the liquid storage container 111 and the liquid storage emptying pipeline, and also to speed up the discharge of waste liquid;

[0111] The cleaning liquid in the liquid storage container 111 can be emptied by providing a liquid storage and emptying pipeline, and the cleaning liquid in the cleaning unit 131 can also be emptied by providing a cleaning liquid emptying pipeline to prevent contamination of the cleaning liquid for the next cleaning.
