Description

Technical Field

[0001] The present invention relates to the field of clean energy for greenhouses, and in particular to a clean energy warming device for use in greenhouses in high-latitude and cold regions. Background Art

[0002] In high-altitude, cold regions, traditional agricultural production methods struggle to meet crop growth requirements due to harsh climatic conditions and extremely low temperatures. Therefore, greenhouses have become a crucial facility for ensuring agricultural output in these regions. However, effectively providing consistent and stable heat for greenhouses in these extreme environments poses a key challenge. Currently, common warming methods include solar heating, coal-fired block heating, and diesel heaters.

[0003] Solar heating, as a clean and environmentally friendly energy source, can theoretically significantly reduce dependence on fossil fuels and lower operating costs. However, in practice, particularly in winter, the significantly shorter daylight hours in high-latitude regions significantly reduce the amount of solar energy collected, which in turn affects heating effectiveness at night and on cloudy days. Furthermore, the high initial investment in solar systems can be a burden for some farmers with limited financial resources.

[0004] While coal-fired block heating offers certain economic advantages, as coal is a relatively inexpensive energy source, its heating efficiency is low and requires frequent refueling, which not only increases labor costs but also makes temperature control difficult. Furthermore, pollutant emissions from coal combustion are a significant concern, especially in enclosed environments like greenhouses, where air quality is directly linked to the healthy growth of crops.

[0005] In contrast, diesel heaters are widely used for their speed and convenience. They not only quickly raise temperatures but also offer relatively low operating costs. However, diesel exhaust contains a significant amount of harmful substances, such as carbon dioxide and carbon monoxide. While exhaust systems are typically used to remove these gases, prolonged operation can still degrade indoor air quality and negatively impact plant growth.

[0006] While existing technologies can address greenhouse warming needs in high-latitude, cold regions to a certain extent, they still face shortcomings in terms of sustainability, cost-effectiveness, and environmental friendliness. Therefore, the search for a more efficient, clean, and automated warming device has become an urgent challenge in this field. Summary of the Invention

Multiple warmers 9 are installed on one wall inside the greenhouse 1. Each warmer 9 has a combustion chamber 905 inside it, which is connected to a gas storage tank 4. The upper end of each warmer 9 is connected to an internal exhaust pipe 6. The internal exhaust pipe 6 extends toward and near the other side of the greenhouse 1. The internal exhaust pipe 6 bends and then passes through the opposite side of the internal wall of the greenhouse 1 to connect to the external exhaust pipe 2. The internal exhaust pipe 6 is installed on the frame of the greenhouse frame 5 via multiple tie rods 7. The gas storage tank 4 of this application is used to store natural gas.

[0028] A plurality of warmers 9 are provided on one wall of the interior of the greenhouse 1. The warmer 9 is mainly responsible for burning natural gas to provide heat. A combustion chamber 905 is provided inside the warmer 9. The combustion chamber 905 is where the natural gas is burned. The combustion chamber 905 is connected to the gas storage tank 4. The gas storage tank 4 is used to store natural gas. This clean energy is not only inexpensive, but also does not produce irritating odors during the combustion process. The upper end of the warmer 9 is connected to the inner exhaust pipe 6, so that the high-temperature smoke generated by the combustion can be transported to the other side of the greenhouse 1 through the inner exhaust pipe 6; the inner exhaust pipe 6 is designed to extend along the other side of the interior of the greenhouse 1, then bend and finally pass through the wall of one side of the greenhouse 1 in the opposite direction and connect to the outer exhaust pipe 2, thereby achieving the exhaust of the smoke; The internal exhaust pipe 6 is fixed to the frame of the greenhouse frame 5 through multiple tie rods 7 to ensure the stability of the pipe; the internal exhaust pipe 6 is arranged in a circuitous manner inside the greenhouse 1, such as Figure 3-5 As shown, the heat emitted can be evenly distributed throughout the greenhouse 1, thereby effectively increasing the temperature inside the greenhouse.

[0029] The coordinated work between the warmer 9 and the internal smoke exhaust pipe 6 can not only continuously provide heat to the greenhouse 1, but also ensure uniform heat distribution, thereby increasing the overall temperature inside the greenhouse 1.

[0030] In a preferred embodiment, the plurality of temperature increasers 9 are connected to the gas storage tank 4 via a fuel pipe 13 , and an electric fuel valve 12 is provided between the fuel pipe 13 and the temperature increaser 9 .

[0031] Multiple heaters 9 serve as the main heat generating equipment. They are all connected to the gas storage tank 4 through the fuel pipe 13 to ensure that natural gas can be stably supplied to the heater 9 for combustion. An electric fuel valve 12 is set between the fuel pipe 13 and the heater 9. The function of the electric fuel valve 12 is to accurately control the time and amount of natural gas entering the heater 9, thereby realizing independent control of the operation of the heater 9.

[0032] Gas tank 4 is mounted on a transport vehicle 11, facilitating both transport and replenishment. Vehicle 11 is also equipped with a main gas source control valve 10, which connects to a fuel pipe 13 and provides overall control over the delivery of natural gas. Adjusting the state of main gas source control valve 10 manages the fuel supply of the entire system.

[0033] In the preferred embodiment, a sleeve 903 is provided at the lower end of the temperature increaser 9, and the combustion chamber 905 is sleeved inside the sleeve 903. The lower end of the combustion chamber 905 is an open structure, and the fuel pipe 13 passes through the sleeve 903 and communicates with the combustion head 906 inside the combustion chamber 905.

[0034] The warmer 9 is the core component of the entire system and is used to provide heat; a sleeve 903 is provided at its lower end, and the main function of the sleeve 903 is to protect and support the combustion chamber 905; the combustion chamber 905 is sleeved inside the sleeve 903, and its lower end is designed to be an open structure to facilitate the entry of natural gas and ignition after mixing with air; the fuel pipe 13 passes through the sleeve 903 and is connected to the combustion head 906 inside the combustion chamber 905 to ensure that the natural gas can be smoothly transported to the combustion head 906; the combustion head 906 is used for the actual natural gas combustion process, generating heat by igniting natural gas, and thus providing the required warmth for the greenhouse.

[0036] The burner head 906 is a cylindrical structure. This design helps the flame extend toward the top of the combustion chamber 905, thereby making the flame burn at a higher height; the upper end of the burner head 906 is close to the top opening of the combustion chamber 905 to ensure that the natural gas can be fully burned and the heat is evenly transferred to the combustion chamber 905; the interior of the burner head 906 is a hollow structure for the circulation of natural gas; a plurality of holes are provided on the surface of the burner head 906, and these holes are tilted upward, so that the burning direction of the flame is upward, further increasing the combustion height, improving the combustion efficiency and the uniformity of heat distribution.

[0037] In the preferred embodiment, a partition is formed between the sleeve 903 and the combustion chamber 905, and a metal coil 904 is wound inside the partition.

The upper end of metal coil 904 is connected to fuel pipe 13, and the lower end is connected to burner head 906. Metal coil 904 preheats the natural gas before it reaches burner head 906, thereby enhancing its heating effect. An ignition needle 907 is also provided on one side of burner head 906. Ignition needle 907 passes through fuel pipe 13 and is located near burner head 906. Ignition needle 907 triggers ignition when needed, igniting the natural gas entering burner head 906. The preheating of metal coil 904 and the ignition of ignition needle 907 ensure more complete combustion of the natural gas within combustion chamber 905, thereby improving the operating efficiency of warmer 9.

Multiple nozzles 908 at the bottom of the warmer 9 are connected to the air pump 3 via an air pipe 15.

The nozzle 908 is connected to the air pipe 15 via the electric valve 14. The electric valve 14 can control the gas supply to ensure that the gas enters the nozzle 908 at the appropriate time and in the appropriate amount. The nozzle 908 achieves the technical effect of increasing oxygen. After the high-pressure gas enters the combustion chamber 905, it blows the internal flame higher, thereby heating the entire pipeline. This method not only improves the combustion effect of natural gas and increases the flame, but also enhances the warming effect.

[0041] In the preferred embodiment, the upper end of the combustion chamber 905 is connected to the heat pipe 901, and the upper end of the heat pipe 901 is connected to the internal smoke exhaust pipe 6; a heating network 902 is provided inside the heat pipe 901, and the heating network 902 is arranged inside the heat pipe 901 through a support block, and a distance is left between the inner wall of the heat pipe 901 and the heating network 902.

[0042] The upper end of the combustion chamber 905 is connected to the heat pipe 901, and the function of the heat pipe 901 is to conduct the heat generated by the combustion chamber 905; the upper end of the heat pipe 901 is connected to the internal smoke exhaust pipe 6, so that the heat energy after combustion can be transferred to the entire greenhouse; a heating network 902 is provided inside the heat pipe 901, and the heating network 902 is arranged inside the heat pipe 901 through a support block, and a certain distance is left between the inner wall of the heat pipe 901 and the heating network 902.
