Simple and human-powered brackish water desalination equipment

Abstract

The invention discloses simple and human-powered brackish water desalination equipment, which at least includes a reverse osmosis device, on a main pipeline in front of the inlet of which a pedal double-piston reciprocating mechanism is installed. The pedal double-piston reciprocating mechanism comprises two piston cylinders, each of which is composed of a cylinder body and a piston assembly. The lower parts of the two cylinder bodies are respectively provided with a water inlet and a water outlet. The two water inlets and the two water outlets are respectively connected through an inlet pipeline and an outlet pipeline which are in connection with the main pipeline. And the water inlets of the two cylinder bodies are all equipped with a check valve. Besides, the two piston assemblies are connected by a lever, among which a fixed hinge fulcrum is disposed. With the weight of an adult, the equipment can press brackish water into a membrane assembly of the reverse osmosis device with a certain pressure so as to ensure a normal operating pressure of the membrane assembly, thus obtaining desalinated drinking water. Without the aid of electric power, the equipment provided in the invention has the advantages of low operation cost and convenient usage.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a simple human-driven brackish water desalination device. Background technique [0002] The taste of brackish water is bitter and it is difficult to drink directly. Long-term drinking will lead to gastrointestinal dysfunction and low immunity. Brackish water is widely distributed in the northern and eastern coastal areas of our country. In these areas, it has been very difficult for people to drink water for a long time. Some people have to drink brackish water for a long time, resulting in various diseases. Kilometers of mountain road back and forth several times to carry water. In recent years, the national government has invested a lot of money and manpower to desalinate the brackish water and solve the problem of drinking water in some areas. [0003] However, there are still some remote mountainous areas where it is not convenient to carry out unified brackish wate...

AI Technical Summary

Problems solved by technology

[0003] However, there are still some remote mountainous areas where it is not convenient to carry out unified brackish water desalination treatment due to the scattered living of people.

Although there are various small-scale brackish water desalination devices suitable for household use, the "reverse osmosis" method is generally used for the desalination of brackish water. Brackish water desalination devices require electricity

However, in these remote mountainous areas, people live in poverty, and the cost of using electricity is high for them. Although the state strongly supports and provides equipment for free, many equipment are left idle due to operating costs.
