Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis devices, in particular to a double reverse osmosis membrane reverse osmosis device. Background Art

[0002] Reverse osmosis devices are commonly used in laboratories. They are used to prepare deionized water and various experiments involving reverse osmosis. The core of reverse osmosis devices is to push water through a semipermeable membrane under high pressure to separate dissolved solids, organic matter, bacteria and viruses in the water, thereby achieving the purpose of purifying water. However, there are still some defects in current reverse osmosis devices, such as:

[0003] The existing single reverse osmosis membrane reverse osmosis device can be used for preparing deionized water and various experiments involving reverse osmosis during use. However, in actual work, when preparing deionized water, it is necessary to conduct experiments immediately, or when preparing deionized water during experiments, or when different experiments are carried out alternately, cross contamination is likely to occur, making the preparation inconvenient. After the experiment, a long cleaning period is required to eliminate the influence of the experimental solution on the membrane in preparing deionized water, and even a new membrane needs to be replaced, making the double reverse osmosis membrane reverse osmosis device inconvenient to use. Utility Model Content

[0004] The utility model aims to provide a double reverse osmosis membrane reverse osmosis device to solve the problem of the need to prepare deionized water or different types of experiments during experiments proposed by the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double reverse osmosis membrane reverse osmosis device, comprising a mounting frame, an inlet pressure gauge, a concentrate pressure gauge, a production water flow meter and a concentrate flow meter, wherein a water inlet pressure gauge is arranged on one side of the top of the mounting frame, a concentrate pressure gauge is arranged on one side of the water inlet pressure gauge, a production water flow meter is arranged on the side of the concentrate pressure gauge away from the water inlet pressure gauge, a concentrate flow meter is arranged on the side of the production water flow meter away from the concentrate pressure gauge, and one end of the top of the mounting frame close to the water inlet pressure gauge is connected to the first valve and the fourth valve respectively.

[0006] Furthermore, the first valve is connected to the water inlet of the first reverse osmosis membrane, and the water outlet of the first reverse osmosis membrane is connected to the water inlet of the second valve and the water inlet of the third valve respectively.

[0007] Furthermore, the fourth valve is connected to the water inlet of the second reverse osmosis membrane, and the water outlet of the second reverse osmosis membrane is connected to the water inlet of the fifth valve and the water inlet of the sixth valve respectively.

[0008] Furthermore, the second valve and the fifth valve are both connected to the water inlet end of the produced water flow meter.

[0009] Furthermore, the water outlet ends of the third valve and the sixth valve are connected to a concentrate flow meter and a concentrate pressure gauge.

[0010] Furthermore, a first valve is disposed on the surface of the produced water flow meter, and a second valve is disposed on the surface of the concentrated water flow meter.

[0011] Furthermore, a water inlet tank is provided at one end of the mounting frame.

[0012] Furthermore, a third valve is arranged on the surface of the water inlet tank, and a fourth valve is arranged on one side of the water inlet tank close to the bottom end of the third valve.

[0013] Furthermore, a fifth valve is provided on a side of the bottom end of the water inlet tank close to the fourth valve, and a sixth valve is provided on a side of the water inlet tank close to the third valve.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the double reverse osmosis membrane reverse osmosis device is connected to two groups of osmotic membranes through a set of equipment, and is shared by other equipment, which saves space and improves purification efficiency. The equipment is mainly designed for laboratory experiments, which effectively saves space. Secondly, the same equipment cannot be used at the same time because it shares a high-pressure pump for water supply. Therefore, the same equipment can be used for different water samples without interfering with each other during cross-tests. It can also be used for the same water sample, and the two membranes are used for scale inhibition and cleaning experiments respectively. In addition, one can prepare ionized water and the other can be used for membrane washing. The water in the water inlet tank is pumped by the water pump. Extraction is performed so that the extracted water can enter the water inlet pressure gauge for detection. At the same time, the first valve, the second valve and the third valve are opened, and the fourth valve, the fifth valve and the sixth valve are closed, so as to control the process of the first reverse osmosis membrane from water inlet to concentrated water and produced water. Conversely, the first valve, the second valve and the third valve are closed, and the fourth valve, the fifth valve and the sixth valve are opened, so as to control the process of the second reverse osmosis membrane from water inlet to concentrated water and produced water. Moreover, the first reverse osmosis membrane and the second reverse osmosis membrane connected by pipelines can quickly switch between different experiments or different uses such as experiments and preparation of deionized water, with little interference with each other.
