Small solar seawater desalination device

Abstract

The invention discloses a small solar seawater desalination device. The small solar seawater desalination device comprises a solar panel, an outer casing, an intermittent water supplying, distilling,medicating and salt absorbing device, two rear wheels and a steering wheel; the solar panel is embedded and mounted on the surface of the outer casing, the bottom of the outer casing is attached to the top of the intermittent water supplying, distilling, medicating and salt absorbing device, the solar panel is connected with the intermittent water supplying, distilling, medicating and salt absorbing device through the outer casing, and the rear wheels are mounted in the rear of the bottom of the intermittent water supplying, distilling, medicating and salt absorbing device. The small solar seawater desalination device has the advantages that the weight of the water used can be detected, the device is stressed by a compression spring when the water slowly reduced, and contacts at both endsare touched upward to start a water pump for water injection, so that desalination efficiency reduction caused by long-time non-injection is avoided; during injection, the mechanical transmission movement can be driven by the power of the water, chemical substances are added automatically, and accordingly, salt utilization rate reduction caused by the fact that obtained impurities are too dense tomake salt salty, bitter and astringent is avoided.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, more precisely, it relates to a small solar seawater desalination device. Background technique [0002] Fresh water has always been an indispensable resource for human beings to survive. With the reduction of fresh water, it is extremely important for human beings to desalinate sea water into fresh water. However, the current small-scale solar desalination device has the following disadvantages: [0003] 1. When the solar desalination device is in use, a large amount of salt will be produced after fresh water distillation, but the impurities will be too dense and the salt will be salty, bitter or astringent, resulting in a decrease in the use rate of salt. [0004] 2. And because when the photovoltaic panels absorb solar energy, the internal temperature is very high, so the desalination speed of fresh water is faster, and the existing water is injected manually. If it is not inject...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a small solar seawater desalination device to solve the problem that when the solar seawater desalination device in the prior art is in use, a large amount of salt will be produced after fresh water distillation, but In this way, the impurities are too dense and the salt is salty, bitter or astringent, which leads to a decrease in the use of salt, and because the internal temperature is very high when the photovoltaic panel absorbs solar energy, the desalination of fresh water is faster, and The existing water is injected manually. When there is no injection for a long time, it will reduce the desalination efficiency.
