At present, the development and utilization of solar energy only need to concentrate on two aspects of power supply and heat supply, and remarkable results are obtained. The solar heat supply is divided into two modes of direct utilization and indirect utilization. Because the solar energy has the defects of dispersion, instability, low efficiency, high development cost and the like, the direct utilization more meets the social requirements. The direct utilization mainly adopts two modes of active solar heat supply and passive solar heat supply.
The active solar system consists of a solar heat collector, a heat storage device, heat utilization equipment, an auxiliary heat source, relevant auxiliary equipment and a valve. When the heat provided by the solar heat collector is insufficient, the auxiliary heating device can be adopted for supplement. The passive solar heat supply is a mode of supplying heat to the indoor space through a heat collection and storage wall, an additional greenhouse, a heat storage roof and the like. The solar radiation is fully collected, stored and distributed in winter by reasonable arrangement of the orientation of the building and the surrounding environment, skillful treatment of the internal space and the external shape and proper selection of building materials and structural construction, so that the indoor temperature of the building can be maintained at a certain temperature.
In industrial production, active solar systems are mainly used for heating. The factory adopts a large-scale solar heat collector, uses water as a heat transfer medium and a heat storage medium, collects solar radiation and converts the solar radiation into heat energy. The solar heat collector is limited to the technical and equipment problems, the heat collection efficiency is not high, the temperature of heat storage medium water can reach 80-95 ℃, if the solar heat collector is used for producing heat supply, an auxiliary heat device is needed to heat water into steam, and about 40% of heat supply energy is saved totally. The utilization of solar energy can integrally save the heat supply energy consumption of enterprises, save the cost and facilitate industrial production.
In some industrial production treatment processes, if the operation temperature can be controlled, hot water generated by the solar heat collector does not need to be heated again, the production activity is directly met, and the production energy can be greatly saved. In general A2O water treatment systemIn the system, all treatment links need to be kept in a certain temperature range throughout the year, the biodegradation activity is ensured, and a large amount of lasting heat energy is needed in the final solid-liquid separation process.
