Problems solved by technology

Since the flow and pressure between the product water of the first-stage reverse osmosis device and the feed water of the second-stage reverse osmosis device are difficult to balance, an intermediate reverse osmosis device is usually installed between the first-stage reverse osmosis device and the second-stage reverse osmosis device. Transition water tank, which will not only increase the investment cost, but also cannot be implemented when the site is limited

Embodiment 1）

[0038] See figure 1 , the integrated two-stage reverse osmosis device of the present invention includes a first booster pump 1, a multimedia filter 2, an activated carbon filter 3, a security filter 4, a first high-pressure pump 5, a first reverse osmosis membrane stack 6, a first Two high-pressure pumps 7 , a second reverse osmosis membrane stack 8 , a first multi-way valve 9 and a second multi-way valve 10 .

[0039] The water inlet of the first booster pump 1 communicates with the raw water inlet 100 through the first pipeline 11-1. The first multi-way valve 9 is arranged on the multimedia filter 2 . The water outlet of the first booster pump 1 communicates with the first interface 9-1 of the first multi-way valve 9 through the second pipeline 11-2. The second pipeline 11-2 is provided with a first manual valve 12-1 and a first pressure gauge 13-1 in sequence. The second port 9-2 of the first multi-way valve 9 communicates with the first port 10-1 of the second multi-way...

Abstract

The invention discloses an integrated two-stage reverse osmosis device. The integrated two-stage reverse osmosis device is characterized by being composed of a first booster pump, a multi-medium filter, an activated carbon filter, a cartridge filter, a first high-pressure pump, a first reverse osmosis membrane stack, a second high-pressure pump and a second reverse osmosis membrane stack. The fresh water outlet of the first reverse osmosis membrane stack is communicated with the inlet of a first electric three-way valve through a seventh pipeline. The first outlet of the first electric three-way valve is communicated with the water inlet of the second high-voltage pump through an eighth pipeline. The second outlet of the first electric three-way valve is communicated with a concentrated water discharge opening through a ninth pipeline. The eighth pipeline is communicated with the ninth pipeline through a tenth pipeline. A second electromagnetic valve and a second check valve are sequentially arranged on the tenth pipeline from the eighth pipeline to the ninth pipeline. A first pressure transmitter is arranged on the eighth pipeline. A fourth electric valve is arranged on a fourteenth pipeline and controlled through a signal of the first pressure transmitter.

Description

technical field [0001] The invention relates to the field of reverse osmosis pure water production, in particular to an integrated two-stage reverse osmosis device. Background technique [0002] At present, the reverse osmosis method has been widely used in the production of pure water. In order to obtain higher purity water, two sets of one-stage reverse osmosis devices will be used in series, which constitutes a two-stage reverse osmosis device. Since the flow and pressure between the product water of the first-stage reverse osmosis device and the feed water of the second-stage reverse osmosis device are difficult to balance, an intermediate reverse osmosis device is usually installed between the first-stage reverse osmosis device and the second-stage reverse osmosis device. Transition water tanks will not only increase investment costs, but also cannot be implemented when the site is limited. Contents of the invention [0003] The object of the present invention is to...
