Problems solved by technology

[0004] Existing solar desalination devices are mainly divided into two types: 1. The main disadvantages of passive solar distillation systems: 1) The latent heat of steam is not reused; 2) The heat capacity of seawater is too large; 3) The natural convection mode in the device limits Improvement of device performance; 2. The main disadvantages of the active

Abstract

The invention discloses a household type solar seawater desalting system. The household type solar seawater desalting system is characterized by comprising a solar electric plate, an electric air pump, a seawater tank, a water inlet tube, a fresh water tank, a fresh water guide tube I, a bubbling-evaporating device, a multi-stage evaporating device and a U-shaped light gathering slot, wherein the seawater tank is arranged above the multi-stage evaporating device; the U-shaped light gathering slot is arranged below the multi-stage evaporating device; the solar electric plate is connected with the electric air pump by virtue of a power wire. According to the household type solar sweater desalting system disclosed by the invention, the conventional distillation technology (passive type distillation) and a bubbling-evaporating technology (active type distillation) are combined and improved, latent heat of steam is recycled, so that not only can the defects of a passive type distillation system be overcome, but also the device is miniaturized, and therefore, the household type solar seawater desalting system is more beneficial to application of island residents.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination, and in particular relates to a household type solar seawater desalination system. Background technique [0002] Seawater desalination is the use of seawater desalination to produce fresh water. It is an open-source incremental technology to realize the utilization of water resources. It can increase the total amount of fresh water without being affected by time, space and climate. The water quality is good and the price is becoming more and more reasonable. It can ensure stable water supply such as drinking water for coastal residents and supplementary water for industrial boilers. The vast areas of our country, such as rural areas and isolated islands, still generally lack electricity. Therefore, under the condition of energy shortage in our country, using solar energy to produce fresh water from seawater is an important way to solve the shortage or insufficient supply of fresh wat...
