Description

Technical Field

[0001] This invention relates to the field of artificial rain enhancement technology, and in particular to a ground-based artificial rain enhancement combustion furnace device. Background Technology

[0002] Artificial rain enhancement technology is an important means of coping with water shortages and alleviating drought disasters. Its core principle is to select the best time to operate based on the physical characteristics of different cloud layers (such as temperature, humidity, and cloud droplet concentration), and seed the clouds with catalysts such as dry ice, silver iodide, and salt powder in a specific way to increase the number of condensation nuclei in the clouds, promote water vapor condensation or sublimation, and ultimately induce cloud precipitation or increase precipitation. Currently, the mainstream rain enhancement catalytic operations are mainly divided into three categories: First, artillery and rocket operations, which use extended-range flammable projectiles and rockets to precisely deliver catalysts to suitable locations in the clouds, where they are released through explosion. However, this requires prior airspace application and has a high cost per operation. Second, aircraft-based catalytic operations, which rely on airborne dispersal devices to achieve large-scale catalyst dispersal with a wide coverage area. However, this is greatly limited by weather conditions (such as low clouds and strong winds) and has high equipment and maintenance costs. Third, ground-based combustion furnace (also known as smoke furnace) operations, which release condensation nuclei by burning smoke containing catalysts. The catalyst is then transported into the clouds by the updrafts on sunny slopes in mountainous areas at specific times. This method is widely used in hilly and mountainous areas of my country where topographic clouds frequently develop due to its low operating cost, simple deployment, adaptability to topographic clouds, and lack of airspace application requirements. In some areas, large-scale rain enhancement operations are also carried out by deploying ground-based smoke furnace matrices to improve operational efficiency.

[0003] Currently, the widely used ground-mounted flue gas stoves in my country have a relatively fixed structure. A typical design usually connects the rain cap, chimney, and furnace body from top to bottom. The core components inside the furnace body include a flue gas holder, a ash collection box, and a fire control device. The flue gas holder is used to stably hold the catalyst flue gas containing silver iodide; the ash collection box collects the ash after the flue gas burns; and the fire control device controls the ignition of the flue gas. For easy observation of the combustion status and ventilation adjustment, observation ports are located on the sides of the furnace body, and ventilation adjustment ports are located at the bottom. Although flue gas stoves used in different scenarios may have slight differences in detailed structure, their working principle is highly consistent: the catalyst flue gas is installed in the flue gas holder, and the flue gas is ignited by manually operating the fire control device. During combustion, the flue gas releases silver iodide dust particles. These particles rise with the hot airflow generated by combustion, are discharged from the furnace body through the chimney, and are then carried into the clouds by external rising air currents. The ventilation adjustment port at the bottom allows outside air to be introduced, providing sufficient oxygen for the continuous combustion of the flue gas and ensuring stable catalyst release. However, this type of ground-based smoke generator with smoke sticks as its core still has significant technical shortcomings: smoke sticks are pyrotechnic items, requiring special explosion-proof warehouses for storage, special vehicles and prior notification for transportation, and strict registration for use. The entire process is subject to numerous regulatory restrictions, resulting in high overall costs and hindering the further promotion of smoke generators in remote mountainous areas and large-scale matrix operations. At the same time, the combustion of smoke sticks is an automatic and continuous combustion mode, which cannot adjust the combustion rate and temperature according to the real-time cloud conditions. Excessive temperature can easily cause silver iodide to sinter and form coarse particles, while insufficient temperature will result in incomplete combustion, directly limiting the effective formation quality of the catalyst and affecting the rain enhancement effect.

[0004] Existing related patents also fail to solve the above problems: Patent CN110056863A is an industrial coal tar combustion device that only optimizes coal tar combustion efficiency and lacks a rain-enhancing catalyst design, making it unsuitable for mountainous scenarios; Patent CN222186937U is a laboratory high-pressure laminar flow flame combustion chamber that requires a sealed environment and precise control, making it unsuitable for outdoor rain enhancement; Although Patent TWM645562U is an artificial rain-enhancing flame agent device, its core "rain-enhancing flame column" is still a pyrotechnic component without combustion control function and still relies on manual loading, failing to overcome existing defects.

[0005] To address these issues, this invention proposes a kerosene-based ground-based artificial rainmaking combustion furnace, and the engineering design has been completed to resolve the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to overcome the aforementioned defects in the prior art and provide a kerosene-based ground-based artificial rain enhancement combustion furnace device that eliminates the need for pyrotechnic devices such as smoke sticks, frequent manual loading and maintenance, and manual control of the combustion process. This simplifies the structure, reduces costs, and is suitable for rain enhancement operations in mountainous areas and unattended environments, while improving operational safety, catalyst formation quality, and automation.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A ground-based artificial rainmaking combustion furnace device, characterized in that it includes a furnace body, a chimney, a combustion organization system, a high-pressure air system, a kerosene supply system, a power supply, a charging port, and a controller; The combustion organization system includes a baffle, an air intake vane, a mounting bracket, a pneumatic nozzle, an ignition nozzle, and a flame thermocouple; The high-pressure air system includes a gas inlet, a high-pressure air tank, a pressure sensor, a temperature sensor, a pressure regulating valve, a switching valve, and gas pipelines. The kerosene supply system includes a filling port, a kerosene storage tank, an oil pump, a liquid flow meter, and kerosene pipelines. The combustion organization system, high-pressure air system, and kerosene supply system are all connected to the controller and are all powered by a power source.

[0008] Furthermore, the baffle is installed inside the furnace body to isolate the left combustion zone inside the furnace body, which is located directly below the chimney; the air intake blade is installed in the lower left part of the combustion zone to introduce external air to assist combustion and increase the flue gas flow.

[0009] Furthermore, the pneumatic nozzles of the combustion organization system are arranged in a ring and installed in the middle of the combustion zone by a fixing bracket, with the nozzles facing upwards. The pneumatic nozzles are connected to the high-pressure air system and the kerosene supply system respectively. The airflow nozzle of the high-pressure air system intersects with the fuel nozzle of the kerosene supply system. The pneumatic nozzles receive high-speed flowing air from the airflow nozzle of the high-pressure air system and receive kerosene mixed with rain-enhancing catalyst from the fuel nozzle of the kerosene supply system, spraying to form the air and fuel mixture required for subsequent combustion and spraying out the air and fuel mixture mist. The ignition nozzle of the combustion organization system is located above the pneumatic nozzle and is used to ignite the air-fuel mixture mist ejected by the pneumatic nozzle. Furthermore, the combustion organization system includes a flame thermocouple installed directly above the pneumatic nozzle, with the probe of the flame thermocouple extending to the upper part of the flame formed by combustion to measure the temperature of the combustion flame and transmit the data back to the controller for regulation.

[0010] Furthermore, the high-pressure air tank of the high-pressure air system has a safety valve, stores high-pressure air, and monitors the gas state inside the tank through the pressure sensor and temperature sensor. The detection data is provided to the controller for comprehensive regulation. Furthermore, the pressure regulating valve of the high-pressure air system is connected to the high-pressure air tank via a gas pipeline, and the switching valve is connected to the pressure reducing and regulating valve via a gas pipeline; The on / off valve of the high-pressure air system is connected to the pressure reducing and regulating valve through a pipeline and is used to control the on / off state of the high-pressure air system.

[0011] Furthermore, the kerosene supply system has a kerosene storage tank that stores a mixture of kerosene and catalyst. The kerosene storage tank is equipped with a stirring device. If the device is not used for a long time and is then used again, the kerosene and catalyst will be mixed evenly by stirring. The oil pump of the kerosene supply system is located downstream of the kerosene storage tank. It is connected to the kerosene storage tank through a kerosene pipeline and to a controller through an electrical circuit. The pumping flow rate is adjusted by the controller. There is a switch valve between the oil pump and the kerosene storage tank. The controller controls the opening and closing of the kerosene supply system according to the needs of rain enhancement operations.

[0012] Furthermore, the liquid flow meter of the kerosene supply system is located downstream of the oil pump, connected via a pipeline, and also connected to the pneumatic nozzle via a pipeline. The flow meter data is fed back to the controller, which is used to adjust the flow rate of kerosene supplied by the oil pump.

[0013] Furthermore, the power source provides electrical energy to all electrical devices; The controller automatically controls the combustion organization system, high-pressure air system, and kerosene supply system to carry out artificial rain enhancement operations according to the program, and transmits relevant operating data back to the artificial rainmaking center, and accepts remote control from the artificial rainmaking center; Furthermore, the power supply is equipped with a charging port for external charging of the rain enhancement device; The high-pressure air system has a high-pressure air tank equipped with a filling port, which is used to manually provide air supply based on the air tank residual pressure data transmitted back to the artificial shadow center by the rain enhancement device. An air compressor is used instead of the high-pressure air tank to provide high-pressure air in real time using outside air. The kerosene supply system has kerosene tanks equipped with refueling ports for manual refueling based on the remaining kerosene data transmitted back to the cloud seeding center by the rain enhancement device. Compared with existing technologies, the kerosene supply system of the present invention has the following advantages: (1) The ground-based artificial rainmaking combustion furnace device provided by the present invention avoids the strict control of smoke strips used in existing ground combustion furnaces, which are classified as pyrotechnics. This device is safer to operate during storage, transportation and use, and is also cheaper, creating conditions for the further promotion and use of ground combustion furnaces.

[0014] (2) The ground-based artificial rainmaking combustion furnace device provided by the present invention is an automatic combustion device compared to smoke bar combustion, and the combustion process cannot be controlled or interrupted. Kerosene is a liquid, which has strong combustion controllability. With the parameter control of the incoming air flow, it can effectively ensure the formation quality of the rainmaking catalyst.

[0015] (3) The ground-based artificial rainmaking combustion furnace device provided by the present invention has a shorter combustion time, more convenient kerosene storage and filling, and can be stored in large quantities, which can effectively extend the service and maintenance cycle of the combustion furnace and facilitate the complete operation of the combustion furnace.

[0016] (4) This invention provides a kerosene-based ground artificial rainmaking combustion furnace device. By replacing the smoke bar with a mixture of kerosene and catalyst as the combustion medium, it eliminates the need for a special explosion-proof warehouse, special transport vehicle and filing and approval process required for smoke bars as pyrotechnics. This significantly reduces the full-cycle control restrictions and reduces the additional costs of storing and destroying pyrotechnics. It is suitable for large-scale smoke furnace matrix operation scenarios in mountainous areas.

[0017] (5) This invention provides a kerosene-based ground-based artificial rainmaking combustion furnace device. By coordinating the high-pressure air system and the kerosene supply system, the combustion temperature and rate are precisely controlled by adjusting the high-pressure air pressure and kerosene flow rate. This avoids the problem of catalyst sintering or incomplete combustion caused by the automatic combustion of the smoke bar, effectively optimizes the quality of effective catalyst formation, and adapts to the differentiated rainmaking operation needs under different cloud conditions.

[0018] (6) This invention provides a kerosene-based ground-based artificial rainmaking combustion furnace device. Through a large-capacity kerosene storage tank and an automatic supply structure, combined with two-way communication between the controller and the artificial rainmaking center, the combustion status can be monitored in real time and remotely controlled. This eliminates the need for frequent manual filling of smoke sticks and ash cleaning, significantly reducing the frequency of manual maintenance and improving the degree of automation. It is suitable for unattended mountainous rainmaking scenarios.

[0019] (7) This invention provides a kerosene-based ground-based artificial rainmaking combustion furnace device. Through the coupling design of power supply and wind and solar power generation equipment, it replaces the traditional single mains power or one-time power supply, solves the pain point of no stable power supply in mountainous areas, avoids the interruption of operation due to power depletion, and improves the long-term continuous operation capability of the device in remote mountainous areas.

[0020] (8) This invention provides a kerosene-based ground artificial rainmaking combustion furnace device. By setting up an air compressor to replace the high-pressure air tank, the frequent gas filling process of the high-pressure air tank is eliminated, avoiding reliance on fixed gas filling facilities. At the same time, combined with pressure sensors to monitor the gas supply status in real time, the stable supply of high-pressure air is ensured, further improving the operational reliability of the device in complex field environments.

[0021] (9) The present invention provides a kerosene-based ground artificial rainmaking combustion furnace device, wherein the pressure regulating valve is used to regulate the gas supply pressure so that the atomization effect is good under a specific fuel flow supply condition.
