Embodiment 1

[0026] In this example, see Figure 1~3 , a forward osmosis membrane water treatment device, including raw liquid unit I, forward osmosis membrane module II and draw solution unit III, forward osmosis membrane module II mainly consists of a mold 3, an annular gasket 2 and a forward osmosis membrane 1, another annular Gasket 2 and another component mold 3 are assembled sequentially to form a spaced cavity container formed by combining two molds 3 mouth to mouth. Both molds 3 are groove molds, and the open sides of the two molds 3 are The open edge is closely combined with both sides of the forward osmosis membrane 1 through the ring gasket 2, so that the forward osmosis membrane 1 forms two cavities, which are respectively used as the raw liquid side cavity and the draw liquid side cavity, and the front side of the forward osmosis membrane 1 Facing the raw liquid side cavity, the supporting surface of the forward osmosis membrane 1 faces the draw liquid side cavity, the mold 3 ...

Embodiment 2

[0034] This embodiment is basically the same as Embodiment 1, especially in that:

[0035] In this example, see Figure 4 , a forward osmosis membrane water treatment device, the raw solution unit I also includes a raw solution storage bottle 5, and the outlet of the raw solution storage bottle 5 passes through an electric pump 10, an inflow valve 8, and a raw solution inlet b to the forward osmosis membrane module II The original solution side cavity of the forward osmosis membrane module II is used to transport the original solution, and the original solution outlet a of the original solution storage bottle 5 in the original solution side cavity of the forward osmosis membrane module II is connected to the water inlet of the original solution storage bottle 5 through a connection valve 9, and the original solution storage bottle 5 Also be provided with a water suction pipe, utilize the negative pressure adsorption effect of the electric pump 10 of stock solution unit 1, draw...

Embodiment 3

[0038] This embodiment is basically the same as the previous embodiment, and the special features are:

[0039] In this embodiment, a forward osmosis membrane water treatment device includes two forward osmosis membrane modules II, forming two sets of spaced cavity containers formed by combining two molds 3 mouth to mouth, and two forward osmosis membrane modules II They are connected in parallel, respectively set between the stock solution unit I and the draw solution unit III. For the components of the forward osmosis membrane, in the actual application process, multiple components can be connected in parallel, and the number of parallel connections is determined according to actual needs. The device of this embodiment is easy to disassemble and assemble, convenient to carry and easy to use. The device of this embodiment can exert its excellent performance in field work, disaster relief, and lack of high-quality water sources.

Abstract

The invention discloses a forward osmosis membrane water treatment device, which consists of a stock solution unit, a forward osmosis membrane component and a solution suction unit. In the forward osmosis membrane component, the surface of a mold is of a saw-toothed and wrinkled structure, a solution can form a vortex flow when passing through the forward osmosis membrane component, and the concentration of the solution is kept unchanged, so that the concentration polarization phenomenon of the surface of a membrane is reduced, and meanwhile, pollution to the surface of the membrane is reduced. In the device, a solar cell is adopted as an energy source for a low-power electric pump, so that the device is more environmentally-friendly and energy-saving. The device is easy to disassemble, assemble and use and convenient to carry. High performance of the device can be achieved under the conditions of fieldwork, disaster relief and high-quality water source lacking.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a filter membrane water treatment device, which is applied in the technical fields of emergency water treatment devices and portable water treatment devices. Background technique [0002] Water is a necessity of life. During daily travel or emergency evacuation, it is usually necessary to carry and replenish drinking water. However, bottled water and barreled water often cause trouble for the carrier due to problems such as large volume and heavy quality. Drinking water or other beverages consumed , also cannot be supplemented. [0003] Forward osmosis currently uses the natural phenomenon that water flows from a place with a high chemical potential to a place with a low chemical potential through a semi-permeable membrane to use a high-concentration draw solution to draw pure water from a low-concentration raw material solution. The whole process occurs naturally without external pre...
