All-weather solar-powered grooved heat collecting and electric heating coupled system

Abstract

The invention provides an all-weather solar-powered grooved heat collecting and electric heating coupled system, which comprises a solar-powered grooved heat collecting region, an electric heating region, a high-temperature reaction region and a system control region. Purified air is pumped into a solar-powered vacuum heat collecting pipe under the driving action of a fan, the air is heated rapidly under the action of a solar-powered grooved heat gathering plate, heated air of which the temperature reaches a temperature required by the high-temperature reaction region is directly applied to a high-temperature reaction, and heated air of which the temperature is lowered than the temperature required by the high-temperature reaction region is subjected to temperature difference compensation through an air heater, so that a constant medium and high-temperature field is formed in the high-temperature reaction region. The effect of the coupled system is that the medium and high-temperature field can be applied to salt solution mesoscopic separation, residual sludge mesoscopic drying and the like. According to the system, an air hot field including hot air of which the temperature is 100-400 DEG C required by the high-temperature reaction region and having the flow of 50-600m<3> / h can be provided in an all-weather way under the coupled control of the solar-powered grooved heat collecting region and the electric heating region.

Description

technical field [0001] The invention relates to a heat supply system, in particular to a medium-high temperature all-weather solar trough heat collection and electric heating coupling system. The invention is a heating and heating system not affected by the weather. The system can provide a constant medium-high temperature air heat field and can be applied to the mesoscopic separation of brine and the mesoscopic drying of excess sludge. Background technique [0002] Energy shortage is a very serious problem facing the world. As a clean and pollution-free new energy source, solar energy has a very broad development prospect. With the research on the large-scale development and utilization of solar energy, it is found that the daylighting rate and The light-to-heat conversion rate is low; the use of solar automatic tracker can make the solar lighting panel always perpendicular to the sunlight, and maintain the maximum light energy collection rate and heat accumulation rate. ...
