Description

Technical Field

[0001] The present invention belongs to the field of air energy technology, and specifically relates to a power generation and heating device based on an air energy boiler.

Background Art

[0002] As an energy conversion facility, the energy input into the furnace body of a boiler has conversion forms from chemical energy in coal, electrical energy, solar energy, etc. to thermal energy. As a heat carrier, it outputs steam, high-temperature water, etc. with a certain amount of thermal energy to the outside. An air source heat pump is an energy-saving device that uses high-level energy to transfer thermal energy from low-temperature heat source air to a high-temperature heat source, and it is a type of heat pump. As the name implies, a heat pump can convert low-level thermal energy (heat contained in air, soil, water) that cannot be directly utilized into high-level thermal energy that can be utilized, like a pump, and can achieve the purpose of saving some high-level energy (such as coal, gas, oil, electrical energy, etc.).

[0003] The Chinese utility model patent with the publication number CN206739254U, as shown in FIGS. 1 to 2, the boiler includes a rotating unit, a rotating shaft, a furnace body, and at least one conversion assembly. The rotating shaft is fixedly attached to the output end of the rotating unit. The rotating shaft has at least one protrusion, and the protrusions are provided one by one corresponding to the conversion assemblies. Each conversion assembly includes a transmission rod, an air cavity, a driving piston, a connecting rod, and a plurality of heating tubes. The driving piston is slidably arranged in the air cavity. The driving piston divides the air cavity into a first cavity and a second cavity. The connecting rod is arranged in the second cavity. The connecting rod is fixedly connected to the driving piston. Both ends of the transmission rod are rotatably connected to the connecting rod and the corresponding protrusion respectively. The first cavity is provided with an air filling port. One end of the plurality of heating tubes communicates with the first cavity. The other ends of the plurality of heating tubes enter the furnace body. The furnace body is hermetically installed. Water is stored in the furnace body. The furnace body is provided with an exhaust port. The exhaust port of the furnace body is connected to each use terminal by a pipe. For the air energy boiler, when the output end of the rotating unit rotates, it drives the rotation of the protrusions on the rotating shaft. The protrusions drive the driving piston to slide in the air cavity through the connecting rod. Then, air is sent into the first cavity, driving the sliding of the piston in the air cavity to compress the air in the first cavity of the air cavity to generate heat. The air that generates heat enters the heating tubes, heats the water in the furnace, evaporates the water into steam, and discharges it to each use terminal through the exhaust port. Since air is used as heating energy, it can quickly reach the required use temperature. There are no restrictions on installation conditions. Since the electrical components do not directly contact water, there is no danger of electric leakage, and the use is safe. The characteristics of energy saving and power saving can avoid the problems in the above-mentioned background technology. Moreover, compared with the heat energy conversion form in the background technology, it has the characteristics of shorter time, faster response time, and higher temperature.

[0004] Currently, power generation and heating using coal and gas are used in many regions. However, coal and gas are non-renewable resources and do not match the current low-carbon goals. Therefore, it is possible to design a device that can utilize air energy for power generation and heating by combining with an air energy boiler.

The driving piston 9 is slidably installed in the air cavity 8. The driving piston 9 divides the air cavity 8 into a first cavity 8a and a second cavity 8b. The connecting rod 10 is installed in the second cavity 8b and is fixedly connected to the driving piston 9. Both ends of the transmission rod 7 are rotatably connected to the connecting rod 9 and the corresponding protrusion 6 respectively. The first cavity 8a is provided with an air filling port.

The furnace body 3 is installed in a sealed manner, water is stored in the furnace body 3, and the furnace body 3 is provided with an exhaust port 11.

[0027] As an option, in the above embodiment, a speed changer is further connected to the rotation shaft of the steam turbine, the rotation shaft of the steam turbine is connected to an input shaft of the speed changer, and an output shaft of the speed changer is connected to the rotation shaft of the air energy boiler.

[0028] As an option, in the above embodiment, a water source is further connected to an inlet of the water purifier.

[0031] Specifically, the operation procedure of the power generation heating device based on the air energy boiler is as follows. 1) Start the feed water pump to fill the air boiler with water; 2) Start the starter motor. The starter motor drives the rotation of the protrusion on the rotating shaft. The protrusion drives the driving piston to slide in the air cavity through the connecting rod. Then, it transports air into the first cavity and drives the sliding of the driving piston in the air cavity of the first cavity to compress and heat the air in the first cavity. After heating, the air enters the heating pipe, heats the water in the furnace, evaporates the water into high-temperature and high-pressure steam, and discharges it to the steam turbine through the exhaust port; 3) The steam turbine is driven by the high-temperature and high-pressure steam to rotate, and outputs the rotational force to the generator through the rotating shaft. The generator generates electricity. 4) After passing through the steam turbine, the high-temperature and high-pressure steam has its pressure and temperature reduced. At this time, the steam is discharged from the exhaust port of the steam turbine and enters the heating pipe. The steam in the heating pipe can provide heat to the outside or be directly cooled. Specifically, 4a) The steam in the heating pipe enters the household heating equipment. After heat exchange, its temperature further decreases and it flows into the water purifier by the condensate pump. 4b) The steam in the heating pipe enters the cooler, exchanges heat with the outside and is cooled in the cooler, and then enters the inlet of the heating pipe by the circulation pump, which is divided into two steps to achieve rapid cooling. 5) The water purifier purifies the flowing condensate water and transports it to the air energy boiler by the feed water pump, forming a complete water circulation according to steps 1 - 5; 6) If there is water loss in all the circulating water, water is supplied to the water purifier by a water source such as a water pipe and added to the circulation.

[0032] Furthermore, the air energy boiler can continuously absorb the low-grade thermal energy in the air and convert it into electrical energy by the steam turbine and the generator. The steam turbine can output the rotational force to the rotating shaft of the air energy boiler by the speed changer. At this time, it is not necessary to always maintain the starter motor in the operating state, and the operation of the whole device can be maintained.

[0033] The above are only preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various modifications and changes are possible to the present invention.
