Problems solved by technology

Its disadvantage is that it is difficult to control the seawater concentration interface in the rotor inclined tube without boundary. Once out of the boundary, the concentrated brine will be mixed into the new raw water, and the efficiency will decrease instead. Therefore, it is difficult to adjust the parameter coupling of the system, and the start-up time of the whole system is long.

Embodiment Construction

[0011] Such as figure 1 As shown: the motor 1 drives the hydraulic oil pump 2, and the oil pump 2 injects the hydraulic oil in the oil tank 5 into the main water pump connected in series to the front end of the desalination membrane device, that is, the hydraulic cylinder of the hydraulic double-cylinder single-acting pump 4, and a relief valve 3 on the way In parallel connection, when the power fluid is injected, it will automatically reciprocate, so that the water pump will inject the raw water in the raw water tank 6 to the water inlet a of the desalination membrane device 7, and the hydraulic oil will drive the high-pressure water pump, and then flow back to the oil tank 5 for endless circulation; the desalination membrane The raw water in device 7 is filtered by membrane m under appropriate high pressure, and the separated fresh water flows from outlet b to fresh water pool 8, and the salt content of seawater in front of the membrane rises to become concentrated brine, and...

Abstract

The invention discloses a reverse osmosis sea-water distillatory with energy recovery, which comprises by desalination membrane equipment, main water pump with hydraulic-oil as active medium and energy recovery pump driving by highly pressurized liquid medium. Wherein main water pump and energy recovery pump build-up conceatenate coupling power-saving device and connect desalination membrane equipment with main pump and energy recovery pump. The merits of this invention are: 1. high efficiency, low noisy; 2. soft start, easy to adjust; 3. simple structure, easy to realize; 4. low cost, easy to spread application.

Description

Technical field: [0001] The invention belongs to a seawater desalination device, in particular to a reverse osmosis seawater desalination device with energy recovery. Background technique: [0002] Membrane separation technology is used in seawater desalination, that is, reverse osmosis seawater desalination (SWRO). In industrial production, the key to reducing energy consumption and achieving commercial value is energy saving. Because the separation object (seawater) is separated by the pores of the membrane under the pressure in front of the membrane, the extract (fresh water) is obtained from the back of the membrane, and the rest of the material (concentrated brine) is still under pressure (energy storage) in front of the membrane. Full of energy. When the continuous flow leaves the outlet of the pressure vessel, in order to maintain the pressure of the vessel, only a small opening can be used. The high-pressure liquid is ejected from the small aperture and emptied, and...
