Efficient water and electricity cogeneration device

Abstract

The invention provides an efficient water and electricity co-production device which comprises a hardware box, a water and electricity co-production chamber and a purified water storage box, a water and electricity co-production module is arranged in the water and electricity co-production chamber and comprises a plurality of water and electricity co-production units, each water and electricity co-production unit comprises a thermoelectric piece, a blue film and CS/PVA aerogel, the blue film is attached to the hot end of the thermoelectric piece, and the CS/PVA aerogel is attached to the hot end of the thermoelectric piece. The cold end of the thermoelectric piece is provided with CS/PVA aerogel, the hot end of the thermoelectric piece faces upwards, the cold end of the thermoelectric piece faces downwards, the shower nozzle sprays water to the water and electricity cogeneration module from bottom to top, the blue film absorbs solar energy, then heat energy is transmitted to the CS/PVA aerogel through the thermoelectric piece, water to be evaporated is provided for the CS/PVA aerogel in a spraying water supply mode, and the water to be evaporated is evaporated through the temperature difference between the two ends of the thermoelectric piece. Purified water and electric energy can be generated simultaneously; the jet water supply mode not only can increase the output of purified water and electric energy of the water and electricity cogeneration module, but also can solve the problems of surface salt deposition, pore channel blockage and the like of the photo-thermal material.

Description

technical field [0001] The invention belongs to the field of solar photothermal technology, and in particular relates to a high-efficiency hydroelectric cogeneration device. Background technique [0002] With the rapid development of modern social economy and human civilization, the use of a series of non-renewable energy sources (such as: coal, oil, etc.) has been greatly enhanced, the problem of energy shortage has become increasingly prominent, and the price has risen sharply. At the same time, during the utilization of fossil fuels, harmful gases, inhalable particles and solid wastes are produced that seriously affect the natural environment and hinder the further improvement of human life quality. Therefore, seeking a renewable, non-polluting and clean energy has become a current research hotspot, which is closely related to the concept of "sustainable development". [0003] As the "source of omnipotence", solar energy is an inexhaustible clean energy source, and the t...
