Description

Technical Field

[0001] The present invention relates to the technical field of industrial and civilian boilers, and in particular to a plasma steam boiler device. Background Art

[0002] A boiler is an energy conversion device. Energy input to the boiler can take the form of chemical energy from fuel or thermal energy from high-temperature flue gases. After conversion, the boiler outputs a certain amount of thermal energy as steam, high-temperature water, or an organic heat carrier. The original meaning of "pot" refers to a container for holding water heated over a fire, while "furnace" refers to the place where fuel is burned. A boiler consists of two main parts: the pot and the furnace. The hot water or steam produced in the boiler can directly provide heat energy for industrial production and daily life. It can also be converted into mechanical energy through a steam power plant, or further converted into electrical energy through a generator.

[0036] The present invention provides a plasma steam boiler device, comprising a plasma system 1, a boiler system 2, and a steam system 3, wherein the front end of the plasma system 1 passes through the boiler system 2 and the outer wall of the plasma system 1 is connected to the boiler system 2 via a flange, and the boiler system 2 and the steam system 3 are connected via a pipeline;

[0037] The plasma system 1 can spray high-temperature plasma 16 and heat the boiler system 2 and the steam system 3; the atomized water in the boiler system 2 can absorb heat to become water vapor and enter the steam system 3; the steam system 3 can absorb moisture in the water vapor to form dry steam, and can reheat the absorbed moisture to form dry steam. The present invention provides a plasma steam boiler device, in which the plasma system uses electricity as energy and generates high-temperature plasma 16 to heat the heat receiving body 23. The hot heat receiving body 23 heats the atomized water in the steam boiler 21 to form water vapor, which then flows through the steam-water separator 31 to form dry steam; at the same time, the high-temperature plasma 16 enters the flash tank 32 from the heat receiving body 23 and heats the water droplets in the flash tank 32 from the steam-water separator 31 to form water vapor. During the operation of the device, no waste that pollutes the environment is generated, and heat is reused, saving electricity, thereby solving the technical problem of steam boilers generating dust, sewage, waste gas and solid waste during operation, which pollutes the environment.

[0038] As an optional embodiment, the plasma system 1 includes a plasma gun 11, an air supply unit 12, an electronic control unit 13, a circulating water unit 14 and an insulating sleeve 15. The plasma gun 11 can adopt a DC non-transferred arc plasma generator. The plasma gun 11 can generate high-temperature, high-enthalpy, high-pressure plasma 16, the heat of which is higher than the heat of ordinary fossil fuel combustion, and the heat is concentrated; the plasma gun 11 is connected to the air supply unit 12 through an air pipeline, and the air supply unit 12 provides the plasma gun 11 with a continuous and reliable ionization medium - compressed air, which is required to be oil-free, water-free, and impurity-free, with a pressure of 0.8 to 1 MPa and a flow rate of not less than 6 Nm3 / h; the plasma gun 11 is connected to the circulating water unit 14 through a water pipeline, and the circulating water unit 14 provides circulating cooling for the plasma gun 11 The water must be pure and deionized, with a temperature not exceeding 35°C, a pressure of 1 to 1.2 MPa, and a flow rate of not less than 8 Nm3 / h. The plasma gun 11 is electrically connected to the electronic control unit 13, which provides the plasma gun 11 with a reliable high-frequency arc ignition power supply, a continuously operating arc ignition and working power supply, and a complete set of automatic control equipment. The insulating sleeve 15 is sleeved on the plasma gun 11 and the plasma gun 11 is cooperatively connected to the insulating sleeve 15. The insulating sleeve 15 insulates the outer shell of the charged plasma gun 11 from the steam boiler 21 to prevent leakage or short circuit. The insulating sleeve 15 can be made of high-temperature resistant mica, ceramic, fiberglass, etc. The plasma gun 11 can continuously spray high-temperature plasma 16. The arc center temperature of the plasma 16 can reach nearly 10,000 degrees, and the resulting hot air flow can reach thousands of degrees.

[0039] As an optional embodiment, the boiler system 2 includes a steam boiler 21, an atomizing nozzle 22 and a heat receiving body 23. The heat receiving body 23 is located in the steam boiler 21 and the heat receiving body 23 is connected to the steam boiler 21 through a bracket 24. The atomizing nozzle 22 is connected to the inner wall of the steam boiler 21. There are multiple atomizing nozzles 22 and all of the atomizing nozzles 22 are evenly distributed on the inner wall of the steam boiler 21. The atomizing nozzle 22 is connected to the water tank through a spray pipe 25. The spray pipe 25 provides the water source required for evaporation and is divided into several branches to the atomizing nozzle 2 2 water supply, requiring the pressure of the spray pipe 25 to be greater than 1 MPa; the atomizing nozzle 22 can spray atomized water into the steam boiler 21, and the atomized water is converted into water vapor after being heated. At the same time, the atomized water can also play a role in cooling the steam boiler 21. The front end of the plasma gun 11 passes through the steam boiler 21 and can spray high-temperature plasma 16 into the heat receiving body 23, thereby heating the heat receiving body 23. When the atomized water falls on the surface of the heat receiving body 23, it will quickly evaporate to generate water vapor. The steam boiler 21 is connected to the steam system 3 through a pipeline.

[0040] As an optional embodiment, the heat receiving body 23 is a funnel-shaped structure and is placed horizontally in the steam boiler 21. The heat receiving body 23 is provided with louvers 231 and air outlets 232. The number of louvers 231 and air outlets 232 is multiple, and all louvers 231 and air outlets 232 are distributed on both sides and the upper part of the heat receiving body 23. The upper part of the heat receiving body 23 is the side close to the steam pipe 4. One end of the louver 231 is fixed to one side of the air outlet 232, and the other side of the louver 231 is tilted up, which increases the contact area between the heat receiving body 23 and the atomized water, and is also conducive to the conduction and diffusion of the hot air flow. The heat receiving body 23 is a carrier that directly converts the atomized water into water vapor and is the core component of the boiler system 2. The heat receiving body 23 is in direct contact with the high-temperature plasma 16. When the enthalpy value of the plasma 16 reaches its peak, it quickly absorbs and stores it, and then releases it. The high-temperature small flow is converted into a low-temperature large flow, providing a larger heat dissipation area and evaporation space. The heating element 23 is made of a material that is resistant to high temperatures, thermal vibrations, erosion, has a large heat capacity, and has a surface that is not easily incinerated, such as corundum, copper, stainless steel, titanium alloy, etc.

[0041] As an optional embodiment, the steam boiler 21 can be a horizontal metal furnace. A furnace door is provided on one side of the steam boiler 21, through which the boiler system 2 can be easily installed and maintained. A connecting hole is provided on the furnace door, through which the plasma gun 11 passes, and the outer wall of the insulating sleeve 15 is connected to the connecting hole by a flange.

[0042] As an optional embodiment, the steam system 3 includes a steam-water separator 31, a flash tank 32 and a water separation tray 33. The steam-water separator 31 is connected to the boiler system 2 through a steam pipe 4. The water vapor generated in the steam boiler 21 enters the steam-water separator 31 through the steam pipe 4. The flash tank 32 is connected to the boiler system 2 through a hot air pipe 5. The plasma hot air flow in the heated body 23 will enter the flash tank 32 through the hot air pipe 5 and heat the flash tank 32. The steam-water separator 31 is connected to the water separation tray 33 through a drain pipe 6. The water droplets separated in the steam-water separator 31 will flow into the water separation tray 33 through the drain pipe 6. The water separation tray 33 is located in the air supply pipe 7 on the flash tank 32. The water droplets in the water separation tray 33 will enter the flash tank 32 through the air supply pipe 7. The air supply pipe 7 is connected to the steam outlet pipe 8 on the steam-water separator 31, and the other end of the air supply pipe 7 is connected to the side of the steam outlet pipe 8.

[0043] As an optional embodiment, the interior of the steam-water separator 31 is equipped with multiple layers of folded plates 311; the lower portion of the steam-water separator 31 is a conical funnel-shaped structure. The function of the steam-water separator 31 is to remove moisture from the steam from the steam boiler 21, leaving dry steam. When the steam passes through the folded plates 311, tiny water droplets strike the folded plates 311 and fall into the conical funnel, entering the drain pipe 6 and then the water diversion tray 33. At the same time, the dry steam bypasses the folded plates 311 and continues on its way to the steam outlet pipe 8.

[0044] As an optional embodiment, a filler 321 is provided in the flash tank 32. The filler 321 is a stainless steel special-shaped filler. The plasma hot air flow entering the flash tank 32 flows through the filler 321, heating the filler 321. At the same time, water droplets falling from the water separation tray 33 flow evenly along the filler 321, fully contacting the surface of the filler 321, undergoing heat exchange, and evaporating the water droplets into water vapor again. This water vapor enters the steam outlet pipe 8 through the air supply pipe 7 and merges with the dry steam in the steam-water separator 31 into the steam outlet pipe 8.

[0045] The flash tank 32 is a cylindrical metal container with a conical bottom. A drain port is provided at the bottom of the flash tank 32 to drain the accumulated water in the flash tank 32. An exhaust pipe 9 is provided on the side of the flash tank 32. This exhaust pipe 9 is the outlet for plasma exhaust gas and can be used as a heat source for the steam superheater or for other purposes.

[0046] As an optional embodiment, a safety valve 41 is provided on the branch of the steam pipe 4. The safety valve 41 is used to prevent the pressure in the steam boiler 21 from being too high. When the steam pressure in the steam boiler 21 exceeds a set value, the valve of the safety valve 41 automatically opens to release the excessive pressure and automatically closes when it returns to normal.

[0047] The working principle of the plasma steam boiler device of the present invention is:

[0048] First, the high-temperature plasma 16 generated by the plasma gun 11 heats the heat receiving body 23 in the steam boiler 21, causing the heat receiving body 23 to absorb and store a large amount of heat energy, which is then diffused and transferred to the entire heat receiving body 23, rapidly increasing its heated surface area until it reaches a red-hot state.

[0049] Next, the atomizing nozzles 22 distributed on the furnace wall of the steam boiler 21 continuously spray atomized water into the steam boiler 21. The atomized water is heated in two ways. First, when tiny water particles suspended in the steam boiler 21 encounter the high-temperature gas, they burst under the high temperature, generating electrons that drift away and stimulate electron movement. The energy of the electron collisions is transferred to the surrounding area, forming large-scale electron collisions, generating secondary heat energy and forming water vapor. When the water vapor leaves the high-temperature area, it stops this movement and rises along the steam pipe 4. Second, water droplets directly falling on the surface of the hot heat receiving body 23 evaporate rapidly after being heated, forming water vapor, which rises along the steam pipe 4.

[0050] Then, the water vapor enters the steam-water separator 31 along the steam pipe 4. The tiny water droplets hit the folding plate 311 and fall into the drain pipe 6, while the dry steam continues to move forward and enters the steam outlet pipe 8.

[0051] Finally, after passing through the heat receiving body 23, the high-temperature plasma 16 enters the flash tank 32 through the hot air duct 5 to heat the filler 321. In addition, the water droplets entering the water distribution tray 33 from the drain pipe 6 enter the flash tank 32 and exchange heat with the hot filler 321, evaporating into water vapor and entering the steam outlet pipe 8 along the air supply pipe 7. It then merges with the dry steam coming out of the steam-water separator 31 and is delivered to the working point.

[0052] High-temperature plasma 16 first uses most of its heat energy to heat the heat receiving element 23. Through diversion, interpenetration, and mixing, the heat receiving element 23 fully absorbs the high-temperature, high-speed plasma 16 jet, evenly heating it. This increases its heat capacity and surface area, accelerating water evaporation. The flow rate of the injected water matches the heating power, ensuring a balance between temperature rise, heat storage, evaporation, and heat dissipation, resulting in a continuous flow of high-temperature steam. The present invention integrates three heat transfer methods: radiation, conduction, and convection, significantly improving heat and mass transfer efficiency and achieving a heat transfer rate far exceeding that of other conventional heat transfer methods.

[0053] Thermal plasma has the characteristics of high enthalpy, high temperature, high speed, concentrated energy and high heat conversion efficiency. It is a new heat source for civilian industry. It has been used in the high-temperature field, but rarely used in the low-temperature field. In fact, there are many aspects of the low-temperature industry that require heating, such as: chemical industry, building materials, medical treatment, textile, papermaking, etc.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
