Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

As shown in Figure 1, a solar boiler system includes a solar collector 1, first and second water pumps 2, 12, a partition heat exchanger 3, a boiler 7, a hot water storage tank 4, and first to third valves 6, 8, 10, heating system 9, hot water supply system 11.

The solar collector 1 is connected to the heat exchanger 3 through a water pump, and is used to absorb solar heat through the heat exchanger 3 to heat water, and the heat exchanger 3 is connected to the hot water storage tank 4, and is used to store the heated water in the heat In the water tank 4, the water outlet of the hot water storage tank 4 is connected to the heating system 9 or the hot water supply system 11 through a water pump and a valve for heating or hot water supply.

The water outlet of the hot water storage tank 4 is connected to the water inlet of the boiler 7 through a water pump and a valve, which is used to heat the water in the heat exchanger 3 that has not been heated to the required temperature in the case of insufficient sunlight; or in the absence of the sun, directly Heat the water in the hot water storage tank 4 to the desired temperature. The water outlet of the boiler 7 is connected to the heating system 9 or the hot water supply system 11 through a valve. The heat exchanger 3 is a partitioned wall heat exchanger, and the partitioned wall heat exchanger is a counterflow heat exchanger.

Solar heat collector 1 is used to obtain solar radiation energy; water pump is used to provide kinetic energy required for flow of water and heat transfer oil; heat exchanger 3 is used for heat exchange between heat transfer oil and water; boiler 7 is used in conjunction with Heating water; hot water storage tank 4, used to store water; valves, used to control the flow direction of heat transfer oil and water, etc.

In actual use, the solar heat collector 1 absorbs heat radiated by sunlight. The circulating working fluid heat transfer oil is heated by the solar heat collector 1 . The heat-conducting oil exchanges heat with the water through the heat exchanger 3, and the water is heated and stored in the hot water tank 4. The hot water in the hot water storage tank 4 can be used directly if the temperature meets the demand. If the hot water in the hot water storage tank 4 does not reach the required temperature, then the boiler 7 is used to reheat the hot water to the required temperature.

When the weather conditions are bad and the solar collector cannot work, the circulating pump between the collector and the heat exchanger will stop running. The solar boiler system is converted to the normal industrial hot water boiler operation mode.
