Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] like Figure 1 As shown, this utility model provides an integrated reverse osmosis device, including a base 1, a membrane seat 2, a module system 3, a scale inhibitor dosing system 4, a membrane cleaning device 5, an automatic control system 6, an inlet water filter 7, an inlet water high-pressure pump set 8, a reducing agent dosing system 9, and a pipe and valve system 10.

[0022] like Figure 2 As shown, module system 3 is fixedly installed on membrane base 2, and membrane base 2 is fixedly installed on base 1. Scale inhibitor dosing system 4 and reducing agent dosing system 9 are respectively fixedly installed on both sides of base 1, forming an installation area. Membrane cleaning device 5, inlet filter 7, and inlet high-pressure water pump are installed within this area. Membrane cleaning device 5, inlet filter 7, and inlet high-pressure pump group 8 are fixedly installed on base 1. Specifically, cleaning filter 51 is installed to the left of scale inhibitor dosing system 4, cleaning pump 52 is installed to the left of cleaning filter 51, inlet high-pressure pump group 8 is installed to the right of reducing agent dosing system 9, and inlet filter 7 is installed to the right of inlet high-pressure pump group 8. Cleaning fluid storage tank 53 is installed below module system 3. Automatic control system 6 is fixedly installed on membrane base 2, and pipe valve system 10 is fixedly installed at the end of module system 3. This arrangement makes the device structure more compact and saves space.

[0023] The module system 3 includes a filter membrane housing 31 and a filter membrane (not shown in the figure). The filter membrane is used to filter impurities in the water. The filter membrane is fixedly installed inside the filter membrane housing 31. The sewage discharge pipe is connected to the inlet high-pressure pump group 8, the inlet filter 7, and the filter membrane housing 31. Specifically, the inlet high-pressure pump group 8 and the inlet filter 7 are installed on the same connecting pipe. One end of the connecting pipe is used to receive sewage, and the other end of the connecting pipe is connected to the filter membrane housing 31. The module system 3 is equipped with a differential pressure detection device to detect the degree of fouling of the filter membrane. Sewage is drawn out by the inlet high-pressure pump group 8, filtered by the inlet filter 7, and then enters the filter membrane housing 31, where it is filtered again by the filter membrane, and then discharged through the pipe valve system 10.

[0024] Because the influent contains strong oxidizing substances and substances that easily cause membrane scaling and hardness, a reducing agent dosing system 9 is set up to inject reducing agents into the influent to eliminate the oxidative damage to the filter membrane caused by oxidizing substances and ensure the service life of the filter membrane. A scale inhibitor dosing device 4 is set up to inject scale inhibitors into the influent to eliminate the scaling and fouling effects of scaling substances on the membrane and maintain the optimal performance of the filter membrane.

[0025] The scale inhibitor dosing system 4 and the reducing agent dosing system 9 consist of a chemical tank, a stirrer, a metering pump, etc. After the device has been running for a period of time, as the filter membrane in the module system 3 continuously intercepts, a layer of pollutants will form on the surface, affecting the desalination effect. The degree of pollution is determined by the differential pressure detection device, and a cleaning section is set up to remove the pollutant layer.

[0026] The membrane cleaning device 5 consists of a cleaning filter 51, a cleaning water pump 52, and a cleaning solution tank 53. The cleaning filter 51, cleaning water pump 52, and cleaning solution tank 53 are all fixedly mounted on the base 1. A return water pipe is provided between the cleaning filter 51, the cleaning solution tank 53, and the filter membrane housing 31. Wastewater in the filter membrane housing 31 flows back to the cleaning solution tank 53 through the return water pipe, thus creating a cycle of cleaning filtrate. Figure 2 As shown, the cleaning filter is installed on the left side of the scale inhibitor dosing system, the cleaning water pump 52 is installed on the left side of the cleaning filter 51, and the cleaning liquid storage tank 53 is installed below the module system 3. The cleaning liquid storage tank 53 stores the cleaning liquid. The cleaning liquid is output by starting the cleaning water pump 52. After passing through the cleaning filter 51 to remove impurities, the cleaning liquid enters the filter membrane in the module system 3 for chemical cleaning. The cleaning method is an internal circulation method until the filter membrane is completely cleaned and the desalination function is restored.

[0027] The automatic control system 6 is electrically connected to the scale inhibitor dosing system 4, the cleaning water pump 52, the inlet high-pressure pump group 8, the reducing agent dosing system 9, and the pipe and valve system 10. When the differential pressure detection device detects that the degree of fouling of the filter membrane meets the standard, the automatic control system 6 sends a signal to perform internal circulation cleaning of the filter membrane.

[0028] The selection of different filter membranes can match different types and functions of membrane modules, such as low-pressure membranes, anti-fouling membranes, seawater desalination membranes, zero-discharge membranes, etc., and can be applied to boiler feedwater, wastewater treatment, reclaimed water reuse, ultrapure water, seawater desalination, zero-discharge and other occasions according to the function of different membranes.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
