Solar energy collection device for drinking water

Abstract

A solar energy collection device for drinking water is mainly formed by full-glass evacuated collector tubes, tube opening plugs, a union water tube, a union gas tube, a gas guide tube, a water level control device, a water feed valve, a water outlet faucet, an electrical heating rod and a frame. The tube opening plugs are fastened in openings of the collector tubes, a branch gas tube, a branch water tube and the electrical heating rod are respectively inserted into circular holes of the tube opening plugs, one end of the union water tube is connected with the water outlet faucet, the other end of the union water tube is connected with the water feed valve, the other end of the water feed valve is connected with one end of a connecting tube, the other end of the connecting tube is connected with a water outlet of a small water tank, a water inlet of the small water tank is connected with a ball float valve, and the other end of the ball float valve is connected with a tap-water tube. The solar energy collection device is mainly characterized in that the openings of the collector tubes face downwards and are longitudinally and tightly distributed to form a block-shaped heat collector; backlight faces of the collector tubes are provided with reflective layers; the union tubes are provided with branch tubes. The solar energy collection device has the advantages that high-quality drinking water can be provided; the unit-area solar energy utilization rate is high; the size is small, and installation is convenient.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a solar energy collection device for drinking water supply. Background technique [0002] Utilizing solar hot water for cooking or solar boiled water for drinking can save heating time and save a lot of energy. The all-glass vacuum heat-collecting tube solar water heater made by the existing technology is difficult to provide fresh and hygienic hot water for cooking and drinking water because of not being able to drain the water inside and the accumulated water. In addition, the all-glass vacuum heat-collecting tube solar water heater made by the current technology can only increase the water temperature but cannot change the water quality. The above reasons have affected the application of the all-glass vacuum heat-collecting tube solar water heater in the energy-saving field. Contents of the invention [0003] Purpose of the present invention: ov...
