Description

Wind and solar integrated heating and heating device

technical field

The invention relates to an energy supply device, in particular to a wind energy and solar energy integrated heating and heating device.

Background technique

The northern region needs heating in winter due to the climate, and coal-fired heating is generally used at present. Although the south does not need heating, there is still a demand for heating. Most of the heating methods are electric heating. At present, the power industry is still dominated by coal thermal power generation. Therefore, heating and heating all need a large amount of coal consumption. As a non-renewable resource, coal will be exhausted if it is continuously used, and the burning of coal has caused serious pollution to the environment. Therefore, the development of new energy heating and heating has become an inevitable trend.

As a clean and renewable energy, wind energy is inexhaustible. The traditional wind energy heating and heating device first converts wind energy into electrical energy, and then utilizes the electrical energy to convert it into heat energy. This method needs to configure a generator for the fan, which increases the input cost. And when the wind speed is greater than the rated wind speed, in order to maintain the rated power of the generator, the fan needs to be controlled by variable pitch to reduce the energy captured from the wind, which results in the incomplete utilization of wind energy. In a year, there are many times when the wind speed is very low, and the energy that can be generated is not enough to overcome the resistance of the fan to make the fan run, so heating cannot be provided for a considerable period of time.

Solar energy is also a clean renewable energy and the construction cost of solar water heaters is relatively low, so it is widely used. However, solar water heaters still have many disadvantages, such as not being able to be used in dark periods such as cloudy days and nights, low light intensity in winter and little rise in water temperature, etc. Electric auxiliary heating is often required, which consumes a lot of electric energy.

How to overcome the shortcomings of the above multiple heating and heating methods and make comprehensive use of their respective advantages has become the original intention of the present invention.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the device of the present invention is mainly composed of a blower fan 1, a speed sensor 2, a quantitative hydraulic pump 3, a first one-way valve 4, an oil charge pump 5, an overflow valve 6, a second one-way valve 7, a filter 8, Fuel tank 9, throttle valve 10, heat exchanger 11, first water switch 12, water reservoir 13, second water switch 14, circulating water pump 15, third water switch 16, fourth water switch 17 and solar heat collector 18 components; the output shaft of fan 1 is connected to one shaft end of quantitative hydraulic pump 3; The pumps are connected in parallel, the oil outlet of charge pump 5 is connected to oil tank 9 through overflow valve 6, the oil suction port of charge pump 5 is connected to oil tank 9 through filter 8, and the oil outlet of charge pump 5 is connected to quantitative The oil suction port of the hydraulic pump 3 is connected, and the oil outlet port of the quantitative hydraulic pump 3 is connected to the oil suction port of the quantitative hydraulic pump 3 after passing through the first check valve 4, the throttle valve 10, and a pipeline inside the heat exchanger 11;

One end of another pipeline inside the heat exchanger 11 is connected to an inlet of the water reservoir 13, and the other inlet of the water reservoir 13 is connected to the outlet of the solar collector 18, and the inlet of the solar collector 18 passes through the second water switch 12 Connect the external cold water source, the other end of the other pipeline inside the heat exchanger 11 is connected to the external cold water source through the second water switch 12, the water storage is provided with two water outlets, and one outlet of the water storage 13 passes through the second water switch 14 outputs hot water, the other outlet of the water reservoir 13 is connected to the input end of the circulating water pump 15, and the output end of the circulating water pump 15 is respectively connected to the inlet of the solar heat collector 18 through the third water switch 16 and the fourth water switch 17 in turn And the other end of another pipeline inside the heat exchanger 11.

For the convenience of understanding, the device is decomposed into the heating part of wind energy heating and the heating part of solar heating.

For the heating part of wind energy heating, the mechanical energy obtained by the fan 1 is transferred to the quantitative hydraulic pump 3 and converted into hydraulic energy, and the energy is transferred through the hydraulic oil in the pipeline. When the hydraulic oil passes through the throttle valve 10, there will be energy loss, and this part of energy loss is It will be converted into heat to increase the temperature of the hydraulic oil, and the energy loss can be controlled by adjusting the opening size of the throttle valve 10 . When the opening of the throttle valve 10 is adjusted to the minimum, the energy loss is the largest and the heat generation is also the largest; if the opening of the throttle valve 10 is adjusted to the maximum, the energy loss is also the smallest and the heat generation is also the smallest.

The heat exchanger 11 is arranged on the hydraulic pipeline at the outlet of the throttle valve 10, which can transfer heat from the hot fluid (hydraulic oil) to the cold fluid (water) to achieve the function of heating water. When the first water switch 12 is turned on, cold water enters the heat exchanger 11 to be heated and stored in the water storage 13 .

In order to prevent the oil from flowing back, the system is provided with a first one-way valve 4 and a second one-way valve 7 . The fan 1 is provided with a speed sensor 2 to detect the wind speed. Considering the impact of leakage on the hydraulic system, an oil replenishment device is provided in the system. The charging pump 5 is connected in parallel with the quantitative hydraulic pump 3, and the charging pump 5 is driven to rotate when the quantitative hydraulic pump 3 rotates. When oil replenishment is not required, the hydraulic oil flows back to the oil tank from the oil tank 9 through the filter 8, oil charge pump 5, and overflow valve 6; when oil replenishment is required, the hydraulic oil is discharged from the oil charge pump 5 and passes through the second one-way valve 7 enter the system.

For the solar energy heating and heating part, cold water enters the solar heat collector for heating through the first water switch 12, and the heated hot water is stored in the water storage device 13.

Under the operation of the device of the present invention, solar energy and wind energy can act simultaneously or independently. When the speed sensor 2 detects that the wind speed is too small to operate the fan, the third water switch 16 is closed to reduce heat loss; when the solar collector cannot work due to cloudy weather, the fourth water switch 17 is closed to avoid heat loss .

The water storage 13 is equipped with a temperature sensor. When the temperature is lower than 90° and the user does not use hot water, the circulating water pump 15 works, and the hot water in the water storage 13 flows back to the heat exchanger 11 for circulation through the third water switch 16 heating. At the same time, hot water enters the solar heat collector for circulation and heating through the fourth water switch 17. Simultaneously, the water reservoir 13 should have a water level sensor to prevent too much or too little water in the water reservoir. When the water level in the water storage 13 was lower than 90% and the second water switch 14 was in the closed state, the first water switch 12 was always in the open state to supplement cold water into the system; when the water level in the water storage 13 was higher than 90% , the first water switch 12 is automatically closed. When the user needs to use it, the second water switch 14 is turned on, and hot water flows in for heating. The system should reduce the loss of heat as much as possible, so the water pipes and the water storage device 13 should be made of thermal insulation materials.

What Fig. 2 shows is the schematic diagram of realizing heating of the present invention. When heating is required, the second water switch 14 is opened, and the water pump 19 injects hot water into the heating pipe 20 to realize heating. The water after passing through the heating pipe 20 enters the heat exchanger 11 and the solar heat collector 18 to be heated through the pipeline circulation again. When heating is not needed, the second water switch 14 is closed. The 3rd water switch 16, the 4th water switch 17 are opened, and circulating water pump 15 work makes hot water enter in heat exchanger 11 and solar heat collector 18 circulation heating (with respect to the output temperature of heat exchanger 11 and solar heat collector 18 lower, relatively cold water). In this example, when the wind energy and solar energy are not working at the same time, the third water switch 16 and the fourth water switch 17 cannot be in the closed state at the same time.

Figure 3 is a schematic diagram of the present invention for realizing heat supply. When heating is required, the second water switch 14 is turned on, hot water enters the water mixing valve 21, and the other end of the water mixing valve is fed with cold water, and after mixing, warm water is output for the user. When not in use, the second water switch 14 and the water mixing valve 21 are closed, and the hot water in the water reservoir 13 enters the heat exchanger 11 and the solar heat collector 18 for circulation and heating through the circulating water pump 15 .

The above specific embodiments are used to explain the present invention, rather than to limit the present invention. Within the spirit of the present invention and the protection scope of the claims, any modifications and changes made to the present invention belong to the protection scope of the present invention.
