Energy-storage solar hot water boiler adopting heat conduction oil to transfer heat and method for preparing hot water

Abstract

The invention relates to an energy-storage solar hot water boiler adopting heat conduction oil to transfer heat and a method for preparing hot water and belongs to a solar energy utilization technology. The steam boiler is characterized by comprising a heat supply device, a heat transfer device buffer container, a heat storage device and an output device which are sequentially connected through a heat transfer medium delivery pipeline to form a circulation loop. A heat transfer medium is heat conduction oil, and a heat storage medium can be molten salt. Different heating modes can be selected according to different environment requirements to ensure that hot water can be supplied constantly even no sunlight is available. The boiler is good in economical benefit, is environmentally friendly, saves energy and reduces initial investment cost due to the fact that an energy storage material can adopt quartz sand compound fused salt invented by the company.

Description

technical field [0001] The invention relates to solar energy utilization technology, in particular to an energy storage solar hot water boiler using heat transfer oil and a method for preparing hot water. Background technique [0002] Industrial hot water is very versatile, used directly, or used to generate steam or high-temperature steam. At present, natural gas boilers and electric heating boilers are used to prepare hot water, but the fuel costs are too high and cause environmental pollution. Solar boilers have become the first choice for industrial hot water preparation. However, there are some defects to be solved in the current solar boiler, for example, it can only work during the day, which reduces the utilization rate of the equipment. In order to solve this problem, some solar boilers combine electric heating at night to improve the operating efficiency of the boiler; on the other hand, the current solar boiler products have high environmental requirements, and ...

Problems solved by technology

But the current solar boilers have some deficiencies to be solved, for example, they can only work during the day, which reduces the utilization rate of equipment

In order to solve this problem, some solar boilers use electric heating at night to improve the operating efficiency of the boiler; on the other hand, the current solar boiler products have high requirements for the environment, and in some environments the low efficiency leads to high operating costs
