Embodiment 1

[0023] With reference to Fig. 1,2,3,4,5, comprise prefilter 1 and reverse osmosis assembly, described reverse osmosis assembly comprises membrane housing 2 and the reverse osmosis membrane 3 that is installed in described membrane housing 2, described The reverse osmosis membrane 3 is provided with a seawater inlet, a desalinated water outlet and a concentrated water outlet, and also includes a suction and discharge piston and a pressure control valve.

[0024] The suction and discharge piston includes a casing 4 with a piston cavity, and a slidable double-effect piston is arranged in the piston cavity, and the double-effect piston separates the piston cavity into a front piston cavity 5 and a rear piston. The sealing ring 29 is used for sealing between the double-effect piston and the inner wall of the piston cavity. The front piston chamber 5 communicates with the seawater inlet of the reverse osmosis membrane through the water outlet pipe 30, and the pre-filter 1 communicat...

Embodiment 2

[0031] 1, 2, 3, 4, 5, the buffer hole of the front piston chamber 5 and the overflow chamber 12, the buffer hole is provided with a safety valve core 26, and the head of the safety valve core 25 is held against At the opening of the buffer hole, the safety valve core is provided with a convex ring, and the housing in front of the mounting nut is screwed with an intermediate nut 27, and the intermediate nut 27 constitutes a protrusion protruding from the inner wall of the buffer hole. Boss, the safety valve core 26 is covered with a safety pressure control spring 28 between the convex ring and the boss, and the inner wall of the front end of the front piston chamber is provided with a head for touching the safety valve core. The top block 33 of the part. The rest of the structure and implementation are the same as in Embodiment 1.

[0032] In the case of a safety valve core, when the pressure rises abnormally during system operation and is about to exceed the maximum withstand...

Abstract

A portable manual seawater desalter comprises a pre-filter and a reverse osmosis component. The reverse osmosis component comprises a membrane shell and a reverse osmosis membrane arranged in the membrane shell; the reverse osmosis membrane is provided with a seawater inlet, a desalted water outlet and a concentrated water outlet; the invention also comprises a water suction and drainage piston and a pressure-control valve; a safety valve can be arranged in the water suction and drainage piston. The beneficial effects of the invention lie in that, 1. the water suction and drainage piston and the pressure-control valve are cleverly designed; when the piston rod is pushed to provide the necessary work operating pressure required by the reverse osmosis membrane, redundant seawater pressure (the pressure of the concentrated seawater) can help to push a piston rod to achieve a real manual desalter; 2, the safety valve can be effective in ensuring the normal operation of desalter to enable a longer service life of the desalter.

Description

(1) Technical field [0001] The invention relates to a portable manual seawater desalination device. (2) Background technology [0002] As water resources become more and more precious today, how to convert seawater into freshwater has become a research hotspot. The basic principle of seawater desalination is to use reverse osmosis membrane for desalination, which requires external force to provide the pressure required for the membrane separation process. At present, seawater desalination technology and equipment relying on electric power are becoming more and more mature, but such seawater desalination equipment not only consumes a lot of energy, but also is very bulky and cannot be carried around. Therefore, a manual portable seawater desalination device has also been proposed. For example, Chinese patents 200420033419.9 and 01106384.X all mentioned a manual seawater desalination device, which utilizes a manual high-pressure pump to provide the pressure required for the m...
