Solar distilled water and hot water combined generation device

Abstract

The invention discloses a solar distilled water and hot water combined generation device. The solar distilled water and hot water combined generation device automatically generates distilled water and hot water through solar radiation, and automatically stops working without solar radiation. Light energy is converted into heat energy through vacuum pipes, liquid water absorbs heat and is vaporized, water steam is guided out of the vacuum pipes and enters a condensation pipe in a hot water tank, the water steam is liquefied into the distilled water in the condensation pipe, and water in the hot water tank is heated into hot water. Repeated utilization of energy is achieved, the two kinds of products are produced, and economic benefits are increased in a multiplied manner. Seawater can be desalinated, potable water can be produced through bitter water in the western region, secondary utilization of domestic water in water-deficient areas is achieved, and the heat efficiency reaches 75%. Automation is achieved for a solar temperature control valve, emission of by-products is avoided due to solar energy, and the life concepts of greenness, environment friendliness and low carbon are met. The technology is simple, operation is convenient, the price is low, the products are safe and practical, the social quantity demand is very large, and the solar distilled water and hot water combined generation device can be domestically and commercially used and has very good development prospects.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a combined production device of solar distilled water and hot water. Background technique [0002] Household solar water heater is the most common device for solar energy utilization. It has simple structure, convenient installation and use, low environmental requirements, and low price. Factors such as heat transfer make the utilization of energy lower; the hot water stored in the vacuum tube (accounting for 1 / 4 of the total water volume) cannot be used. [0003] At present, the device that uses solar energy to produce water vapor requires high pressure and is not yet mature in technology; according to the high temperature (up to 350°C) generated by the solar vacuum tube drying, it can vaporize water, changing the traditional way of energy transfer. The vacuum tube vaporizes water at normal pressure, transfers heat energy through water vapor, produces hot water, and liquef...

[0003] At present, the device that uses solar energy to produce water vapor requires high pressure and is not yet mature in technology; according to the high temperature (up to 350°C) generated by the solar vacuum tube drying, it can vaporize water, changing the traditional way of energy transfer. The vacuum tube vaporizes water at normal pressure, transfers heat energy through water vapor, produces hot water, and liquefies water vapor to obtain distilled water. A solar distilled water and hot water combined production device is designed.
