Technical Field

[0001] This invention relates to a high-temperature steam hot air blower that generates heat through rotational collision, belonging to the category of thermal machinery or gas machinery. Background Technology

[0002] Currently, some pneumatic high-temperature hot air blowers used by people can only produce high-temperature hot air, not high-temperature steam. Moreover, the high-temperature hot air produced has relatively low thermal efficiency and low air temperature, resulting in a narrow range of applications and failing to meet people's diverse needs for high-temperature heat energy in production and daily life. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a rotary collision-generated high-temperature steam hot air blower that can generate both high-temperature steam and high-temperature hot air, with high temperature rise, high thermal efficiency, multiple functions, wide range of applications, more energy saving, more environmental protection, and can meet people's various needs for high-temperature heat energy in production and life.

[0004] The technical solution of this invention is as follows: A rotating collision heating high-temperature steam hot air blower includes a casing, a casing air inlet, a casing air outlet, a blower impeller, an impeller bushing, a casing inner cavity, and a casing side wall. The characteristic is that a spiral rotating guide vane is provided in the casing inner cavity. The spiral rotating guide vane does not have connecting components (such as a central shaft or hub) in its radial direction. The entire spiral rotating guide vane is longitudinally flexible and can be bent and twisted. The entire spiral rotating guide vane can be square or cylindrical. The spiral rotating guide vane is connected to the inner side of the casing side wall through its radial end edge. The spiral rotating guide vane is fixed together with the casing side wall and, like the casing side wall, is a fixed stationary component. The spiral rotating guide vane, with the support and blocking of the casing side wall, forms a spiral rotating type inner flow channel within the casing.

[0005] To further achieve the purpose of this invention, the side wall of the casing is a clamping wall type, and the inner side wall of the clamping wall of the casing is a screen structure. The inner cavity of the casing is equipped with a spiral rotating guide vane. The radial end edge of the spiral rotating guide vane is connected to the inner side wall of the clamping wall of the casing. The spiral rotating guide vane, with the support and blocking of the inner side wall of the clamping wall, forms a spiral rotating inner flow channel of the casing, which is connected to the heat generation chamber of the casing clamping wall space through the screen mesh vents of the inner side wall of the clamping wall.

[0006] To further achieve the purpose of this invention, a spiral rotating guide vane is provided inside the air inlet of the housing. The radial end edge of the spiral rotating guide vane is connected and fixed to the inner side wall of the air inlet of the housing. The spiral rotating guide vane forms a spiral rotating air inlet inner flow channel with the support and blocking of the inner side wall of the air inlet of the housing.

[0007] To further achieve the purpose of the present invention, a spiral rotating guide vane is provided inside the air outlet of the housing. The radial end edge of the spiral rotating guide vane is connected and fixed to the inner side wall of the air outlet of the housing. The spiral rotating guide vane forms a spiral rotating type inner flow channel of the air outlet of the housing with the support and blocking of the inner side wall of the air outlet of the housing.

[0008] To further achieve the purpose of this invention, a spiral rotating guide vane is provided inside the external pipe of the air inlet of the housing. The radial end edge of the spiral rotating guide vane is connected and fixed to the inner side wall of the external pipe of the air inlet of the housing. The spiral rotating guide vane forms a spiral rotating type internal flow channel of the external pipe of the air inlet of the housing by means of the support and blocking of the inner side wall of the external pipe of the air inlet of the housing.

[0009] To further achieve the purpose of this invention, a spiral rotating guide vane is provided inside the external pipe of the air outlet of the housing. The radial end edge of the spiral rotating guide vane is connected and fixed to the inner wall of the external pipe of the air outlet of the housing. The spiral rotating guide vane forms a spiral rotating type internal flow channel of the external pipe of the air outlet of the housing by means of the support and blocking of the inner wall of the external pipe of the air outlet of the housing.

[0010] For ease of narration and accuracy, a few related terms will be explained below:

[0011] The impeller's central axis points axially, and the impeller sidewall or sidewall, or the casing sidewall or sidewall, are called axial sidewalls or axial sidewalls.

[0012] The side of the impeller or machine body facing the motor is the axial rear side, and the opposite side is the axial front side.

[0013] The direction perpendicular to the impeller's central axis is radial. The part closest to the impeller's axis is the radial front of the impeller, and its front end is the radial front end of the impeller. The part closest to the outer circumference of the impeller is the radial rear of the impeller, and its outer edge is the radial end of the impeller. The designations for related parts of the casing follow the same principle. The impeller's rotation direction is circumferential. The direction of impeller rotation in the same direction as the impeller is either forward rotation or circumferential forward, and the direction of rotation away from the impeller is either backward rotation or circumferential backward.

[0014] Air inlet orientation designation: the air inlet of the housing is the front, the air inlet outlet of the housing is the rear, and other orientations within the air inlet of the housing are designated accordingly.

[0015] Impeller flow channel refers to the flow channel inside the impeller and the blade flow channel; the blade is the flow passage component, and the blade flow channel is the blade itself.

[0016] The same model and serial number of the product equipment of this invention can process cold water into high-temperature steam and cold air into high-temperature hot air, so it is named high-temperature steam hot air machine; and because it generates heat by using the principle of rotational collision heat generation, it is named rotational collision heat generation high-temperature steam hot air machine.

[0017] When cold water is processed into high-temperature steam, the cold water enters the impeller of the fan and is atomized into water mist. The water mist then generates heat and absorbs heat under the effect of rotation and collision and is vaporized into water vapor, also called cold steam. The cold steam then generates heat and absorbs heat under the effect of rotation and collision and becomes high-temperature steam. Water mist, cold steam, and steam are all referred to as vapor or steam flow.

[0018] The technical description of processing cold air into high-temperature hot air refers to air, cold air, hot air, and gas flow as described above. Gas refers to air gas, and flow refers to air flow.

[0019] The terms "gas (vapor)" and "airflow (vapor flow)" used in the technical specifications are explained as follows:

[0020] Since this technology can process both cold water into high-temperature steam and cold air into high-temperature hot air, the technical specifications must take both into account; gas (vapor), where gas refers to processing cold air into high-temperature hot air, and vapor refers to processing cold water into high-temperature steam; airflow (vapor flow), where airflow refers to processing cold air into high-temperature hot air, and vapor flow refers to processing cold water into high-temperature steam.

[0021] This invention relates to a high-temperature steam hot air blower that generates heat through rotational collision. It does not require any other heat source or heat medium. It generates high-temperature steam or hot air by relying solely on the rotation of the blower impeller to create a rotational collision heat generation effect, which is used to meet people's production and daily life needs.

[0022] The so-called principle of rotational collision heat generation is that the cold air or cold water entering the fan body is first processed into high-pressure, high-speed airflow (steam flow) by the fan impeller. The high-pressure, high-speed airflow (steam flow) is then processed into high-pressure, high-speed, high-intensity cyclone airflow (steam flow) by the spiral rotating guide vanes. The high-intensity cyclone airflow (steam flow) repeatedly rotates and collides with the gas (vapor) in the machine body components and the machine body to generate and absorb heat, forming high-temperature or ultra-high-temperature hot air or high-temperature steam, which is then discharged from the machine body for other uses.

[0023] Compared to the principles of oscillation-induced heat generation, induction-induced oscillation-induced heat generation, and energy-concentrating heat generation, the rotational collision-induced heat generation principle has a stronger heat generation effect and generates more heat due to the greater intensity and impulse of the cyclone airflow (vapor flow) formed by rotation and repeated cyclical rotation and collision. As a result, more heat is generated and absorbed by the cold air or cold vapor, and the gas (vapor) temperature rises higher, thus its thermal efficiency is higher and it saves more energy.

[0024] This invention's rotary collision-generated high-temperature steam hot air blower boasts higher thermal efficiency than conventional pneumatic, energy-concentrating, oscillating, and induction-oscillating high-temperature hot air blowers, achieving a thermal efficiency similar to that of heat pump air conditioners. However, it is structurally simpler than heat pump air conditioners, requiring no heat source or heat medium, and is unaffected by weather conditions or geographical environments (it can operate in sub-zero temperatures of tens of degrees below zero and even hundreds of degrees Celsius). The rotary collision-generated high-temperature steam hot air blower is multifunctional and versatile, capable of producing both high-temperature steam and high-temperature hot air, including ultra-high-temperature hot air exceeding 1000°C or ultra-high-temperature steam exceeding 100°C for everyday use—a feat impossible for heat pump air conditioners.

[0025] This invention can replace various boilers, heat pumps, coal stoves, oil stoves, electric stoves, electric heating equipment, solar energy equipment, etc. in many ways, and can partially replace gasoline engines, diesel engines and other heat engines in certain fields.

[0026] The present invention relates to a rotating collision-generated high-temperature steam hot air blower, comprising a casing, a casing air inlet, a casing air outlet, a fan impeller, an impeller bushing, a casing inner cavity, and a casing side wall. A spiral rotating guide vane is provided in the casing inner cavity. The spiral rotating guide vane is connected and fixed to the inner side surface of the casing side wall through its radial end edge. Like the casing side wall, it is a fixed stationary component. The spiral rotating guide vane forms a spiral rotating inner flow channel of the casing with the help of the casing support and blocking.

[0027] This invention features a spiral rotating guide vane with no connecting components such as a drive shaft or hub in the radial center; the radial center is hollow. The entire spiral rotating guide vane is flexible in the longitudinal direction, allowing it to bend and twist. The entire spiral rotating guide vane can be square or cylindrical (perfectly circular, square-circular, or flattened cylindrical). The spiral rotating guide vane is connected to the inner side wall of the casing via its radial edge. The spiral rotating guide vane is fixed to the casing side wall, making it a stationary component that does not rotate or move, does not perform work on the gas (vapor), and does not propel the gas (vapor) flow. It acts as a directional collision guide for the gas (vapor). Within the inner flow channel of the casing, it can redirect and guide the direct-flowing gas (vapor) into a cyclone flow (vapor). Therefore, the gas (vapor) discharged from the fan impeller naturally becomes a cyclone flow (vapor) when it enters the inner flow channel of the spiral rotating casing.

[0028] The spiral rotating guide vane can be fixed to the inner sidewall of the casing by connecting its radial end edges on all four sides, i.e., to the inner sidewalls of both the front and rear radial sidewalls and the front and rear axial sidewalls of the casing, thus forming a fully enclosed spiral rotating inner flow channel. Alternatively, it can be fixed to the inner sidewall of the casing by connecting its radial end edges on three, two, or one side, thus forming a semi-enclosed spiral rotating inner flow channel. The fully enclosed spiral rotating inner flow channel does not contact the outside environment, and the cyclone airflow (vapor) flowing inside does not collide with the outside environment. The semi-enclosed spiral rotating inner flow channel is in contact with its corresponding external environment, and the cyclone airflow (vapor) flowing inside directly collides with its corresponding external machine parts and flowing gas (vapor).

[0029] The inner cavity of the casing of this invention generally employs a semi-enclosed spiral rotating type inner flow channel. During operation, a portion of the high-pressure, high-speed airflow (vapor) discharged from the fan impeller is discharged into the semi-enclosed spiral rotating type inner flow channel, forming a high-intensity cyclone (tornado) airflow (vapor). During this spiral rotating cyclone airflow (vapor) flow, the direction of the airflow (vapor) continuously changes, causing the gas molecules to collide violently and generate heat, thus raising the temperature. During operation, another portion of the high-pressure, high-speed airflow (vapor) discharged from the impeller is blocked and flows unidirectionally in the space outside the spiral rotating type inner flow channel. This unidirectional airflow (vapor) directly and violently collides with the cyclone airflow (vapor) in the spiral rotating type inner flow channel, creating a collision-generated heat effect, generating heat, and raising the temperature.

[0030] It is quite obvious that the inner flow channel of the semi-enclosed spiral rotating casing can promote a double collision heating effect, thus generating more heat and a higher gas (vapor) temperature rise, which can produce ultra-high temperature hot air or ultra-high temperature steam.

[0031] The casing sidewall of this invention can be a single-layer structure or a double-layer / multi-layer sandwich structure. The double-layer / multi-layer sandwich structure casing sidewall has a casing sandwich space within it, and a casing sandwich space collision heat-generating chamber is located within this space. The inner sidewall of the casing sandwich wall has a screen structure, and the casing sandwich space collision heat-generating chamber is connected to the inner casing flow channel through the screen mesh vents on the inner sidewall of the casing sandwich wall. Thus, a spiral rotating guide vane is installed within the casing cavity formed by the casing sidewall composed of double-layer / multi-layer sandwich walls, and this spiral rotating guide vane forms a spiral rotating inner casing flow channel. The casing sandwich space collision heat-generating chamber is then connected to this spiral rotating inner casing flow channel through the screen mesh vents on the inner sidewall of the casing sandwich wall. During operation, the spiral rotating casing forms a cyclone airflow (vapor flow) in the inner channel, which collidees with the gas (vapor) in the heat-generating chamber of the casing through the mesh holes of the inner wall of the casing, creating a collision heating effect and generating heat.

[0032] If the inner flow channel of the spiral rotating casing is semi-enclosed, as described earlier, during operation, the high-intensity cyclone airflow (vapor flow) formed within the inner flow channel directly collides with the direct-flow airflow (vapor flow) on the outside of the inner flow channel, generating heat. In this way, the high-intensity cyclone formed within the inner flow channel generates heat both internally and externally, through collisions with the gas (vapor) in the casing's internal heat-generating chamber and with the unidirectional flow (vapor flow) on the outside of the inner flow channel. This triple heating effect results in even more heat being generated and a higher gas (vapor) temperature. This structural technology can produce even higher temperatures of ultra-high-temperature hot air or ultra-high-temperature steam.

[0033] Because the spiral rotating guide vane technology can directly control the cyclone airflow (vapor flow), and the cyclone airflow (vapor flow) can efficiently promote the collision heating effect, efficiently generate heat, and increase the gas (vapor) temperature, thus efficiently producing high-temperature hot air or high-temperature steam, this technology can be widely used in the field of pneumatic hot air blower technology. This technology can be used in any mechanical structure space where gas (vapor) flows (containing sufficient mechanical energy) in order to obtain a certain amount of heat energy. For example, in this invention, spiral rotating guide vanes can be installed in the inner cavity of the casing, the air inlet of the casing, the air outlet of the casing, the external pipe connecting the air inlet of the casing, and the external pipe connecting the air outlet of the casing to form a spiral rotating pipe inner flow channel.

[0034] The installation of spiral rotating guide vanes inside the casing cavity has already been described. The following sections describe the technical solutions related to the installation of spiral rotating guide vanes in the casing air inlet and outlet, and in the external ducts connecting to the casing air inlet and outlet.

[0035] A spiral rotating guide vane is installed inside the air inlet of the casing. The radial edge of the guide vane is connected and fixed to the inner wall of the air inlet. The spiral rotating guide vane, supported and blocked by the inner wall of the air inlet, forms a spiral rotating air inlet channel. Cold air or cold water from outside is drawn into the spiral rotating air inlet channel and directly rotates and collides to generate and absorb heat, becoming warm air (vapor). This warm air (vapor) is then drawn into the fan impeller and processed into a high-pressure, high-speed warm airflow (vapor flow). This high-pressure, high-speed warm airflow (vapor flow) is then discharged into the spiral rotating air inlet channel inside the casing cavity, where it undergoes a triple collision to generate and absorb heat, becoming a high-temperature and ultra-high-temperature cyclone airflow (vapor flow).

[0036] A spiral rotating guide vane is installed inside the air outlet of the casing. The radial edge of the guide vane is connected and fixed to the inner wall of the air outlet. The spiral rotating guide vane, supported and blocked by the inner wall of the air outlet, forms a spiral rotating inner flow channel. The high-temperature hot air or high-temperature steam processed through the spiral rotating inner flow channel enters the air outlet and is further heated by collision and heat absorption, becoming even higher-temperature hot air or high-temperature steam.

[0037] A spiral rotating guide vane is installed inside the air outlet of the casing. The cold air (cold water) entering the fan body will undergo five collision heat generation effects: the collision heat generation effect of the spiral rotating air inlet channel, the collision heat generation effect of the spiral rotating air inlet channel inside the casing cavity, and the collision heat generation effect of the air outlet channel. Naturally, more heat is absorbed, which can produce ultra-high temperature hot air >1000℃ or high temperature steam >100℃. The thermal efficiency of the hot air blower will be very high.

[0038] To further generate more heat, increase gas temperature, improve thermal efficiency, and save energy, this invention can also install spiral rotating guide vanes in the external conveying pipes of the housing inlet and outlet, and construct spiral rotating flow channels on the inner side of the external pipes of the housing inlet and outlet. The spiral rotating guide vanes installed in the external pipes of the housing inlet and outlet have essentially the same structural principle, device method, function, and purpose as those installed in the external pipes of the housing inlet and outlet. The spiral rotating guide vanes in the external pipes of the housing inlet form the spiral rotating flow channels on the inner side of the external pipes of the housing inlet, and the spiral rotating guide vanes in the external pipes of the housing outlet form the spiral rotating flow channels on the inner side of the external pipes of the housing outlet.

[0039] The spiral-shaped flow channel inside the external duct of the air inlet preheats the cold air or water entering the fan body before it enters the air inlet and inner cavity of the casing for gradual heat generation and absorption. Similarly, the spiral-shaped flow channel inside the external duct of the air outlet further heats the ultra-high temperature hot air or steam discharged from the fan body after processing, further increasing the heat and raising the temperature. Therefore, incorporating spiral-shaped guide vanes in the external ducts of the air inlet and outlet can improve the thermal efficiency of the steam hot air blower and save energy.

[0040] Based on the spiral rotating inner flow channel technology of the external pipe of the air inlet and outlet of the casing, it is entirely possible to set up a dedicated hot air delivery pipe with self-generated heat. That is, high-pressure, high-speed (with sufficient mechanical energy) cold air is input into the spiral rotating inner flow channel and flows. During the flow, the cold air is automatically converted into hot air and delivered to the destination for use.

Implementation

[0054] Example 1, Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 A high-temperature steam hot air blower for generating heat through rotational collision includes a casing 1, a casing air inlet 2, a casing air outlet 3, a fan impeller 4, an impeller shaft sleeve 5, a casing inner cavity 6, and a casing side wall 7. The fan impeller 4 is located in the casing inner cavity. A flat cylindrical spiral rotating guide vane 8, made of 304 stainless steel plate bent and rotated, is located in the radial rear part of the casing inner cavity. The entire flat cylindrical spiral rotating guide vane 8 forms a longitudinal ring and falls in the radial rear part of the casing inner cavity. The radial rear edge of the spiral rotating guide vane 8 follows the casing. The inner side of the radially rear sidewall of the casing and the inner side of the axially front and rear sidewalls of the casing are connected and fixed together. That is, the three edges of the spiral rotating guide vane 8 are connected to the casing sidewall. The spiral rotating guide vane 8 forms a spiral rotating casing inner flow channel 9 by means of the support and blocking of the three casing sidewalls. The spiral rotating casing inner flow channel 9 is closed to the outside on three sides and open to the impeller on one side (radial front side) by means of the blocking of the casing sidewalls on the radially rear side and the axially front and rear sides, forming a semi-closed casing inner flow channel.

[0055] This embodiment is equipped with a high-power motor 19, and the fan impeller adopts a high-power high-pressure blower impeller. The motor shaft is connected to the fan impeller, and the motor 19 directly drives the fan impeller 4 to rotate, so as to cause the steam hot air blower to form a heat-generating working state.

[0056] In this embodiment, all structural components of the steam hot air blower are made of food-grade 304 stainless steel.

[0057] This embodiment is used to generate high-temperature steam >100℃ for use in food factories, mines, schools, and other kitchens for heating and processing food.

[0058] During operation, the fan impeller draws in cold water from the air inlet 2 of the casing and processes it into a high-pressure, high-speed steam flow. After exiting the fan impeller 4, this high-pressure, high-speed steam flow collides and flows radially and circumferentially directly against the open side (towards the impeller) of the inner flow channel 9 of the spiral rotating casing. During this collision flow, a portion of the steam flow crashes into the inner flow channel of the spiral rotating casing, forming a cyclone steam flow. Another portion of the airflow collides with the cyclone steam flow simultaneously. The high-pressure, high-speed steam flow discharged from the impeller impacts the inner flow channel of the spiral rotating casing, simultaneously creating a double collision heating effect. That is, the cyclone steam flow itself generates heat through internal collision, and simultaneously, it also generates heat through collision with the high-pressure, high-speed steam flow discharged from the impeller that collides with the inner flow channel of the spiral rotating casing but does not enter it. Because it is a double collision heating effect, its thermal efficiency is high.

[0059] Because this embodiment uses a high-power high-pressure blower impeller, the steam discharged from the impeller has high pressure and high velocity. The discharged steam has a strong impact force on the inner flow channel of the spiral rotating casing, with a large collision force and a large impulse, which can generate a large flow of high-temperature steam with a temperature greater than 100°C. This high-temperature steam is then discharged from the machine body through the air outlet 3 of the casing for use in food heating and processing.

[0060] Example 2, Reference Figure 5 , Figure 6 , Figure 7 , Figure 8 This embodiment is basically the same as Embodiment 1, except that the radial sidewall 7 of the casing is a double-layer sandwich structure, the inner sidewall 10 of the casing sandwich is a screen structure, and the sandwich space is provided with a casing sandwich space collision heat generation chamber 12 separated by 30 steel strips. The radial rear edge of the spiral rotating guide vane 8 provided in the radial rear part of the casing cavity 6 is connected and fixed to the radial rear side of the casing sandwich inner sidewall 10. The axial front and rear edges of the spiral rotating guide vane 8 are connected and fixed to the casing sandwich inner sidewall 10. The radial rear and axial front and rear sides of the spiral rotating casing inner flow channel 9 formed by the spiral rotating guide vane 8 are connected to the casing sandwich space collision heat generation chamber 12 through the screen holes 11 of the casing sandwich inner sidewall. The radial front side of the spiral rotating casing inner flow channel 9 is fully open to the fan impeller 4, and can directly receive the collision of the high-pressure and high-speed airflow discharged by the fan impeller.

[0061] The second difference is that, in this embodiment, both the air inlet 2 and the air outlet 3 of the housing are provided with spiral rotating guide vanes 8. The spiral rotating guide vanes 8 in the air inlet of the housing are connected and fixed together with the inner side wall of the air inlet of the housing, and the spiral rotating guide vanes 8 in the air outlet of the housing are connected and fixed together with the inner side wall of the air outlet of the housing. The spiral rotating guide vanes 8 on the inner side of the air inlet of the housing form a fully enclosed spiral rotating type inner flow channel 13 of the air inlet of the housing, and the spiral rotating guide vanes 8 on the inner side of the air outlet of the housing form a fully enclosed spiral rotating type inner flow channel 14 of the air outlet of the housing.

[0062] During operation, the high-pressure, high-speed airflow discharged from the fan impeller directly impacts the inner flow channel 9 of the spiral rotating casing in a circumferential radial direction. A portion of this airflow enters the flow channel, forming a cyclone. During this cyclone flow, it generates heat through internal collisions, as well as through collisions with the gas in the casing's internal space and heating chamber 12 via the screen holes 11 on the inner wall of the casing's inner wall. Additionally, it generates heat through collisions with the high-pressure, high-speed airflow from the fan impeller in a radial-frontal direction, creating a triple collision heating effect. This triple collision heating effect results in better heat generation and produces more heat.

[0063] Because the inner side of the air inlet of the housing in this embodiment is provided with a spiral rotating guide vane 8, and the inner flow channel of the air inlet of the housing is a spiral rotating flow channel, when working, the cold airflow entering the housing first enters the inner flow channel 13 of the spiral rotating housing air inlet to form a cyclone airflow. The cyclone airflow collides and generates heat, and the rotating cold air becomes warm air. It is then sucked into the fan impeller for processing, and then processed into high-temperature hot air through the inner flow channel of the spiral rotating housing before being discharged to the air outlet of the housing.

[0064] Since the inner side of the air outlet of the casing is also provided with a spiral rotating guide vane 8 and a spiral rotating type air outlet inner flow channel 14, the high-temperature hot air processed in the inner cavity of the casing enters the spiral rotating type air outlet inner flow channel 14, and is processed to generate and absorb heat, resulting in a higher temperature high-temperature hot air, which is then discharged from the machine body for use.

[0065] In this embodiment, the cold air entering the machine undergoes five stages of processing to generate and absorb heat, ultimately producing ultra-high temperature hot air with higher heat content and a higher temperature rise. This example can produce ultra-high temperature hot air >1000℃.

[0066] This embodiment has higher thermal efficiency and saves more energy.

[0067] In this embodiment, if the air inlet of the steam hot air blower is specifically designed to draw in room temperature clean water, it can directly produce high-temperature steam with a large flow rate greater than 200°C, which can be used in chemical industry workshops to process chemical products.

[0068] Example 3, Reference Figure 9 , Figure 5 , Figure 6 , Figure 7 , Figure 8 This embodiment is basically the same as embodiment 2, except that in this embodiment, an external air inlet pipe 15 is provided on the outside of the air inlet 2 of the housing. The external air inlet pipe 15 is connected to the inlet of the air inlet 2 of the housing. The front end of the external air inlet pipe 15 is provided with an outwardly expanding horn-shaped air inlet 20. A spiral rotating guide vane 8 is provided inside the external air inlet pipe 15. The radial peripheral edge of the spiral rotating guide vane 8 is connected and fixed to the inner side wall of the external air inlet pipe. The spiral rotating guide vane forms a spiral rotating type inner flow channel 16 of the external air inlet pipe through the inner side wall of the external air inlet pipe.

[0069] This embodiment is used for a natural wind-assisted heat-generating rotary collision heat-generating high-temperature steam hot air blower. The front end of the external pipe 15 of the air inlet of the casing has a horn-shaped air inlet 20 that leads to the outside. The horn-shaped air inlet 20 is adjustable and always faces the wind direction of the outside sky, directly receiving the air volume and wind force blown in from the outside sky.

[0070] During operation, the funnel-shaped air inlet 20 of the external pipe of the casing is adjusted to face the outside airflow. The outside airflow is directly blown into the funnel-shaped air inlet, where it gathers and contracts, increasing pressure and speed. Then it enters the inner channel 16 of the external pipe of the spiral rotating casing air inlet, and flows into the casing air inlet 2. During the flow, with the help of the directional collision induction effect of the spiral rotating guide vane 8, its mechanical energy is continuously converted into heat energy. In this way, the cold air becomes a warm air with a relatively high temperature. This warm air then flows into the inner channel 13 of the spiral rotating casing air inlet 2, where it flows and generates heat, becoming an even higher temperature warm air. This higher temperature warm air then enters the fan impeller for further pressurization and speed-up, becoming a high-pressure, high-speed warm air. This high-pressure, high-speed warm air is then discharged into the inner channel 9 of the spiral rotating casing, which is a clamp-type structure on the side wall of the casing, where it flows and absorbs heat, becoming a high-temperature hot air. This high-temperature hot air is then discharged from the machine body for other uses.

[0071] Obviously, this embodiment uses natural wind power to directly process hot air, which naturally saves energy. The stronger the natural cold wind, the higher the temperature rise of the steam hot air blower, and the more heat is generated, thus saving even more energy.

[0072] Example 4, Reference Figure 10 , Figure 5 , Figure 6 , Figure 7 , Figure 8 This embodiment is basically the same as embodiment 2, except that in this embodiment, an external pipe 17 for the air outlet 3 of the housing is provided on the outside of the housing air outlet 3, and the external pipe 17 for the housing air outlet is connected to the housing air outlet; a general-purpose high-power exhaust fan 21 is provided on the outside of the external pipe 17 for the housing air outlet, the exhaust fan inlet 22 of the high-power exhaust fan 21 is connected to the outlet of the external pipe for the housing air outlet, and an exhaust fan duct 24 is provided on the outside of the exhaust fan outlet 23.

[0073] The external pipe 17 of the air outlet of the casing is equipped with a spiral rotating guide vane 8. The radial periphery of the spiral rotating guide vane 8 is connected and fixed to the inner wall of the external pipe of the air outlet of the casing. The spiral rotating guide vane forms a spiral rotating type internal flow channel 18 of the external pipe of the air outlet of the casing through the inner wall of the external pipe of the air outlet of the casing.

[0074] This embodiment is used for conveying ultra-high temperature hot air in processing and production.

[0075] During operation, the casing sidewalls are fitted with a rotating collision-generating high-temperature steam hot air blower and a powerful induced draft fan 21, which are powered on and running simultaneously.

[0076] When the hot air blower is operating, the cold air drawn in through the air inlet 2 of the casing is first processed into high-temperature hot air through the spiral rotating inner flow channel 13 of the casing air inlet. This hot air then enters the fan impeller and is processed into high-pressure, high-speed hot air. This high-pressure, high-speed hot air then flows into the spiral rotating inner flow channel 9 of the casing, which has a clamped side wall, and flows to generate heat and become high-temperature hot air. This high-temperature hot air is then processed into even higher-temperature ultra-high-temperature hot air through the spiral rotating inner flow channel 14 of the casing air outlet. This ultra-high-temperature hot air is discharged into the spiral rotating outer flow channel 17 of the casing air outlet. The air flows through the side channel 18. Due to the strong suction of the powerful induced draft fan 21 at the outlet of the casing air outlet, the ultra-high temperature hot air absorbs the gravitational kinetic energy transmitted by the powerful induced draft fan, which increases the pressure and speed of the flow. At the same time, it is also adjusted and depressurized by the collision of the inner side channel 18 of the spiral rotating casing air outlet air outlet, which generates heat and increases the temperature. Finally, it is processed into ultra-high temperature hot air (>1000℃) with low pressure and low speed. This ultra-high temperature hot air with low pressure and low speed is then pressurized and accelerated by the powerful induced draft fan, becoming high pressure and high speed ultra-high temperature hot air. It is then discharged from the powerful induced draft fan body and discharged to the destination through the induced draft fan exhaust pipe 24.

[0077] In this embodiment, the air inlet can be specifically designed to draw in cold water, which is then processed into ultra-high temperature steam. Because a high-powered induced draft fan is installed on the outside of the outlet pipe of the steam hot air blower, the ultra-high temperature steam processed by the steam hot air blower is further pressurized and accelerated by the induced draft fan, ultimately producing high-pressure ultra-high temperature steam for special industrial production applications.
