Description

Technical Field

[0001] This application relates to the field of cold air steam heater technology, specifically a cold air steam heater. Background Technology

[0002] With the deep integration of green building and intelligent technology, intelligent ecological buildings have become the mainstream direction of industry development. These buildings, with "efficiency, environmental protection, and humanization" as their core objectives, need to achieve harmonious coexistence with nature through technological integration. Precise indoor temperature and humidity control and efficient energy utilization are key requirements, which place higher demands on the performance of supporting environmental control equipment.

[0003] In the temperature and humidity control system of intelligent eco-friendly buildings, the cold air steam heater is one of the core devices, and its technological level directly affects the building's energy consumption and living comfort. Existing cold air steam heaters have initially integrated steam heating technology with the concept of eco-friendly buildings. They release latent heat (which accounts for over 90% of the total heat of the steam) through the condensation of high-temperature steam in finned tube bundles, and utilize the fins to expand the heat exchange area, achieving efficient heating of cold air to the target temperature. Simultaneously, the liquid water formed by steam condensation can be discharged and recovered through a condensate drain, achieving preliminary energy recycling. Some devices also integrate the SMARTControl intelligent system, which can automatically adjust the steam flow and water pump speed according to the indoor and outdoor temperature difference, improving energy efficiency by more than 30% compared to traditional equipment, providing technical support for energy optimization in intelligent eco-friendly buildings.

[0004] Chinese utility model patent CN213630368U discloses a steam heater with a circulating heating mechanism. This heater collects steam through connecting pipes to avoid environmental pollution caused by direct emissions, while simultaneously enabling the secondary use of steam condensate to reduce water waste. A one-way valve mechanism ensures sufficient heating of water in the fixed outer casing, accelerating steam generation. However, this patent and most existing similar technologies only focus on the circulation of steam and water recovery, neglecting the significant waste heat generated during the operation of intelligent eco-friendly buildings (such as equipment heat dissipation and waste heat from air conditioning systems). This fails to integrate building waste heat with the steam heating system for tiered energy utilization, resulting in continued energy waste. This contradicts the concept of "full-process energy optimization" in intelligent eco-friendly buildings and hinders further improvements in overall building energy efficiency.

[0005] In summary, although existing cold air steam heaters have made progress in heating efficiency and basic energy saving, they still suffer from insufficient energy utilization due to the lack of effective integration and utilization of building waste heat. Therefore, this application provides a cold air steam heater to solve the above problems. Utility Model Content

[0006] This application provides a cold air steam heater, which aims to solve the problems mentioned in the background art. Existing cold air steam heaters and related technologies only focus on the circulation of steam itself and the recovery of water resources. They do not effectively utilize the large amount of waste heat generated during the operation of intelligent ecological buildings (such as equipment heat dissipation, waste heat from air conditioning systems, etc.), and cannot combine building waste heat with steam heating systems to achieve energy cascade utilization. As a result, energy waste still exists, which does not conform to the concept of "full-process energy optimization" of intelligent ecological buildings and restricts the further improvement of the overall energy utilization efficiency of buildings.

[0007] To achieve the above objectives, this application provides the following technical solution: a cold air steam heater, comprising a steam heating module, a heat exchange module, and an ecological heat source acquisition module; the steam heating module includes a water storage tank and a waste heat conduction coil disposed within the water storage tank for connection to an external heating return water pipe; the heat exchange module includes a heat exchange tube and a heat exchange coil disposed within the heat exchange tube, both ends of the heat exchange coil penetrating the heat exchange tube, and the input end of the heat exchange coil being connected to the water storage tank via a pipe, and an air outlet pipe being disposed at the bottom of the heat exchange tube; the ecological heat source acquisition module includes a centrifuge cylinder, an air inlet pipe disposed at the top of the centrifuge cylinder, and an exhaust pipe disposed in the middle of the centrifuge cylinder, the output end of the exhaust pipe penetrating the centrifuge cylinder and connected to the heat exchange tube. During use, the waste heat conduction coil connected to the external heating return water pipe heats the water in the storage tank, and the generated water vapor enters the heat exchange coil through the pipe; external waste steam enters the centrifuge tube through the air inlet pipe and rotates, and water droplets are thrown against the inner wall of the centrifuge tube and slide down under the action of centrifugal force. Clean steam enters the heat exchange tube through the middle exhaust pipe and comes into contact with the heat exchange coil to exchange heat. The high temperature water vapor in the heat exchange coil heats the gas in the heat exchange tube, and the heated gas is discharged through the air outlet pipe to provide indoor heating.

[0008] Preferably, to improve the heating efficiency of the heat exchange coil for the gas inside the heat exchange tube, heat dissipation fins are fitted onto the heat exchange coil. This significantly improves the heating efficiency of the heat exchange coil for the gas inside the heat exchange tube, accelerates the gas temperature rise, and enhances the overall heat exchange performance of the equipment.

[0009] Preferably, to facilitate the recovery and reuse of water vapor within the heat exchange coil: a first recovery pipe is fixedly connected to the output end of the heat exchange coil, and the end of the first recovery pipe is connected to the air inlet pipe. This enables the recovery and reuse of water vapor within the heat exchange coil, reduces steam waste, further improves the energy utilization rate of the equipment, and conforms to the concept of ecological energy conservation.

[0010] Preferably, to facilitate the movement of water vapor into the heat exchange coil, the top of the water storage tank is conical. This guides the water vapor generated in the water storage tank to move more smoothly into the heat exchange coil, preventing water vapor from stagnating at the top of the water storage tank and improving steam delivery efficiency.

[0011] Preferably, to facilitate the discharge of waste liquid from the water storage tank: the bottom of the water storage tank is conical, and a drain valve is installed at the bottom of the water storage tank; a water inlet pipe is installed at the top of the water storage tank. This facilitates the rapid discharge of waste liquid and impurities from the water storage tank, preventing their accumulation from affecting equipment operation, and also facilitates the replenishment of water into the water storage tank, ensuring continuous and stable operation of the equipment.

[0012] Preferably, to facilitate centrifugal motion of waste steam inside the centrifuge tube, the output end of the air inlet pipe is tangent to the inner wall of the centrifuge tube. This allows the waste steam to quickly and stably form centrifugal motion after entering the centrifuge tube, improving the separation efficiency of water droplets and steam in the waste steam and ensuring the quality of steam entering the heat exchange tube.

[0013] Preferably, to improve centrifugation efficiency, the top of the centrifuge tube is cylindrical, and the bottom is conical. This improves the centrifugation efficiency of the centrifuge tube for waste steam, ensures thorough separation of water droplets in the waste steam, and guides the separated water droplets to be discharged quickly, thereby enhancing the equipment's ability to process waste steam.

[0014] Preferably, to facilitate centralized collection of condensate: a water collection tank is fixedly connected to the bottom of the centrifuge cylinder, a drain valve is fixedly installed at the bottom of the water collection tank, and the end of the heat exchange coil is connected to the water collection tank through a second recovery pipe. This achieves centralized collection and management of condensate, avoiding waste or pollution caused by indiscriminate discharge of condensate, and also facilitates subsequent reuse of condensate.

[0015] Preferably, to facilitate the intake of external cold air into the heat exchange tube, the system further includes a fan housing, a drive shaft mounted within the fan housing via a sealed bearing, a fan impeller fixedly mounted on the drive shaft, and a drive component for driving the drive shaft to rotate. A filter screen is provided at the inlet end of the fan housing, and the outlet end of the fan housing is connected to the heat exchange tube. This allows for convenient and efficient intake of external cold air into the heat exchange tube while simultaneously filtering impurities, ensuring the cleanliness of the gas entering the heat exchange tube and guaranteeing a stable heat exchange process.

[0016] Preferably, the driving component includes a sealed housing fixedly mounted on the centrifuge drum and communicating with the heat exchange coil. A fan housing is fixedly mounted on the upper end of the sealed housing. The bottom of the drive shaft passes through the fan housing and the sealed housing and extends into the centrifuge drum. Vertical shaft impellers are provided inside both the sealed housing and the centrifuge drum. The vertical shaft impellers are fixedly mounted on the drive shaft and correspond to the airflow. No additional external power is required to drive the fan; the equipment utilizes its own airflow for propulsion, saving energy consumption and further enhancing the equipment's eco-friendly and energy-saving characteristics.

[0017] This application effectively reduces building heating energy consumption through waste heat recovery, while simultaneously achieving steam recycling and efficient gas heating, meeting the energy-saving and temperature and humidity control requirements of intelligent eco-friendly buildings. External waste steam enters the centrifuge tube through the inlet duct and rotates. Water droplets are thrown against the inner wall of the centrifuge tube and slide down under the action of centrifugal force. Clean steam enters the heat exchange tube through the central exhaust duct and comes into contact with the heat exchange coil for heat exchange. The high-temperature water vapor in the heat exchange coil heats the gas inside the heat exchange tube, and the heated gas is discharged through the outlet duct to provide heating to the room.

[0018] This application connects the output end of the heat exchange coil to the air inlet pipe via a first recovery pipe, enabling the recovery and reuse of water vapor in the heat exchange coil, reducing steam waste, further improving the energy utilization rate of the equipment, and conforming to the concept of ecological energy conservation.

[0019] This application uses a second recovery pipe to discharge the condensate in the heat exchange coil into a collection tank, thereby achieving centralized collection and management of the condensate, avoiding waste or pollution caused by the random discharge of condensate, and facilitating the subsequent reuse of the condensate.

[0020] This application utilizes steam to drive the vertical shaft impeller to rotate, which in turn drives the drive shaft and the fan impeller to rotate. This allows for the convenient and efficient intake of external cold air into the heat exchange tubes, eliminating the need for additional external power to drive the fan. The equipment's own airflow enables the drive, saving energy consumption and further enhancing the equipment's eco-friendly and energy-saving characteristics. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] This embodiment provides a cold air steam heater, such as Figure 1-6 As shown, the heater includes a steam heating module 1, a heat exchange module 2, and an ecological heat source acquisition module 3. The steam heating module 1 includes a water storage tank 11 and a waste heat conduction coil 12 installed inside the water storage tank 11 for connection to an external heating return water pipe. The heat exchange module 2 includes a heat exchange tube 21 and a heat exchange coil 22 installed inside the heat exchange tube 21. Both ends of the heat exchange coil 22 penetrate the heat exchange tube 21, and the input end of the heat exchange coil 22 is connected to the water storage tank 11 via a pipe. An air outlet pipe 23 is installed at the bottom of the heat exchange tube 21. The ecological heat source acquisition module 3 includes a centrifuge cylinder 31, an air inlet pipe 32 installed at the top of the centrifuge cylinder 31, and an exhaust pipe 33 installed in the middle of the centrifuge cylinder 31. The output end of the exhaust pipe 33 penetrates the centrifuge cylinder 31 and is connected to the heat exchange tube 21. Waste heat recovery effectively reduces building heating energy consumption while simultaneously achieving steam recycling and efficient gas heating, meeting the energy-saving and temperature and humidity control requirements of intelligent ecological buildings. During use, the waste heat conduction coil 12, which is connected to the external heating return water pipe, heats the water in the storage tank 11. The generated water vapor enters the heat exchange coil 22 through the pipe. External waste steam enters the centrifuge cylinder 31 through the air inlet pipe 32 and rotates. Water droplets are thrown against the inner wall of the centrifuge cylinder 31 and slide down under the action of centrifugal force. Clean steam enters the interior of the heat exchange tube 21 through the middle exhaust pipe 33 and comes into contact with the heat exchange coil 22 for heat exchange. The high-temperature water vapor in the heat exchange coil 22 heats the gas in the heat exchange tube 21. The heated gas is discharged through the air outlet pipe 23 to provide heating to the room.

[0031] Among them, the water storage tank 11 and waste heat conduction coil 12 of the steam heating module 1 are made of 304 stainless steel; the heat exchange tube 21, heat exchange coil 22 and air outlet duct 23 of the heat exchange module 2 are made of 304 stainless steel; and the centrifuge tube 31, air inlet duct 32 and air outlet duct 33 of the ecological heat source acquisition module 3 are made of 304 stainless steel.

[0032] To improve the heating efficiency of the heat exchange coil 22 for the gas inside the heat exchange tube 21, heat dissipation fins 221 are fitted onto the heat exchange coil 22. This significantly improves the heating efficiency of the heat exchange coil 22 for the gas inside the heat exchange tube 21, accelerates the gas heating rate, and enhances the overall heat exchange performance of the equipment. The heat dissipation fins 221, fitted onto the heat exchange coil 22, can quickly diffuse the heat from the surface of the heat exchange coil 22 into the internal space of the heat exchange tube 21, increasing the contact area between the heat and the gas inside the heat exchange tube 21, allowing the gas to absorb heat more fully, thereby improving heating efficiency.

[0033] Among them, the heat dissipation fins 221 are made of aluminum alloy.

[0034] To facilitate the recovery and reuse of water vapor within the heat exchange coil 22, a first recovery pipe 222 is fixedly connected to the output end of the heat exchange coil 22, and the end of the first recovery pipe 222 is connected to the air inlet pipe 32. This enables the recovery and reuse of water vapor within the heat exchange coil 22, reducing steam waste and further improving the energy efficiency of the equipment, in line with the concept of ecological energy conservation. With the output end of the heat exchange coil 22 fixedly connected to the first recovery pipe 222, the usable water vapor within the heat exchange coil 22, after participating in heat exchange, is transported through the first recovery pipe 222 to the air inlet pipe 32, where it enters the centrifuge 31 along with external waste steam for separation and treatment, and then participates again in subsequent heat exchange processes, achieving recycling.

[0035] The first recycling pipe 222 is made of 304 stainless steel.

[0036] To facilitate the movement of steam into the heat exchange coil 22, the top of the water storage tank 11 is conical. This guides the steam generated in the water storage tank 11 to move more smoothly into the heat exchange coil 22, preventing steam from stagnating at the top of the water storage tank 11 and improving steam transport efficiency. The conical top of the water storage tank 11, when heated by the waste heat conduction coil 12 to generate steam, causes the steam to rise due to buoyancy. The inclined surface of the conical top guides the steam, causing it to concentrate and move towards the pipe opening in the central area of ​​the top of the water storage tank 11, thus smoothly entering the heat exchange coil 22 through the pipe.

[0037] The cone-shaped part at the top of the water storage tank 11 is consistent with the main body of the water storage tank 11 and is made of 304 stainless steel.

[0038] To facilitate the discharge of waste liquid from the water storage tank 11: the bottom of the water storage tank 11 is conical, and a drain valve is installed at the bottom of the water storage tank 11, while a water inlet pipe is installed at the top of the water storage tank 11. This allows for the quick and easy discharge of waste liquid and impurities from the water storage tank 11, preventing their accumulation from affecting equipment operation. It also facilitates the replenishment of water into the water storage tank 11, ensuring continuous and stable operation of the equipment. The conical bottom of the water storage tank 11 causes waste liquid and impurities to accumulate towards the tip of the cone due to gravity. When drainage is required, the drain valve at the bottom is opened, allowing the accumulated waste liquid and impurities to be quickly discharged. When the water level in the water storage tank 11 is low, water is added through the water inlet pipe at the top, ensuring that the waste heat conduction coil 12 can continuously heat and generate steam.

[0039] The bottom conical part of the water storage tank 11 is made of 304 stainless steel, the same as the main body of the water storage tank 11, the drain valve is made of brass, and the inlet pipe is made of 304 stainless steel.

[0040] To facilitate centrifugal motion of waste steam inside the centrifuge cylinder 31, the output end of the air inlet pipe 32 is tangential to the inner wall of the centrifuge cylinder 31. This allows the waste steam to quickly and stably form centrifugal motion after entering the centrifuge cylinder 31, improving the separation efficiency of water droplets and steam in the waste steam and ensuring the quality of steam entering the heat exchange tube 21. With the output end of the air inlet pipe 32 tangential to the inner wall of the centrifuge cylinder 31, when external waste steam is transported through the air inlet pipe 32, it enters the cylinder along the tangential direction of the inner wall of the centrifuge cylinder 31, forming an airflow rotating along the inner wall, thereby generating centrifugal force and creating favorable conditions for subsequent separation of water droplets and steam.

[0041] The air inlet pipe 32 is made of 304 stainless steel, and the centrifuge cylinder 31 is made of 304 stainless steel.

[0042] To improve centrifugation efficiency, the top of the centrifuge cylinder 31 is cylindrical, and the bottom is conical. This enhances the centrifugation efficiency of the centrifuge cylinder 31 for waste steam, ensuring thorough separation of water droplets from the waste steam and guiding the separated droplets out quickly, thereby improving the equipment's waste steam processing capacity. The cylindrical top of the centrifuge cylinder 31 provides a stable rotation space for the waste steam, ensuring continuous centrifugal motion; the conical bottom allows separated water droplets to slide down the inner wall of the cone under gravity, preventing water droplets from accumulating inside the cylinder, thus improving overall centrifugal separation efficiency.

[0043] The top cylindrical part and the bottom conical part of the centrifuge tube 31 are both made of 304 stainless steel.

[0044] To facilitate centralized collection of condensate: a water collection tank 4 is fixedly connected to the bottom of the centrifuge cylinder 31, and a drain valve is fixedly installed at the bottom of the water collection tank 4. The end of the heat exchange coil 22 is connected to the water collection tank 4 through a second recovery pipe 223. This achieves centralized collection and management of condensate, avoiding waste or pollution caused by indiscriminate discharge of condensate, and facilitating subsequent reuse of condensate. The bottom of the centrifuge cylinder 31 is fixedly connected to the water collection tank 4, and water droplets separated inside the centrifuge cylinder 31 slide down into the water collection tank 4; condensate formed by the condensation of water vapor in the heat exchange coil 22 also flows into the water collection tank 4 through the second recovery pipe 223; when the condensate in the water collection tank 4 reaches a certain amount, the drain valve at the bottom can be opened to discharge the condensate, facilitating subsequent recycling.

[0045] Among them, the water collection tank 4 is made of 304 stainless steel, the drain valve is made of brass, and the second recovery pipe 223 is made of 304 stainless steel.

[0046] To facilitate the intake of external cold air into the heat exchange tube 21, the system includes a fan housing 5, a drive shaft 51 mounted within the fan housing 5 via a sealed bearing, a fan impeller 52 fixedly mounted on the drive shaft 51, and a drive component 53 for rotating the drive shaft 51. A filter screen 54 is installed at the inlet end of the fan housing 5, and the outlet end of the fan housing 5 is connected to the heat exchange tube 21. This system conveniently and efficiently draws external cold air into the heat exchange tube 21 while filtering impurities, ensuring the cleanliness of the gas entering the heat exchange tube 21 and guaranteeing stable heat exchange. The drive component 53 drives the drive shaft 51 to rotate (the drive shaft 51 is mounted within the fan housing 5 via a sealed bearing). The drive shaft 51 drives the fan impeller 52, which is fixedly mounted on it, to rotate. The rotation of the fan impeller 52 generates suction, drawing external cold air into the fan housing 5. The cold air first passes through the filter screen 54 at the inlet end of the fan housing 5 to remove impurities, and then enters the heat exchange tube 21 through the outlet end of the fan housing 5, providing the gas to be heated for subsequent heat exchange.

[0047] Among them, the fan casing 5 is made of 304 stainless steel, the drive shaft 51 is made of 45 steel, the fan impeller 52 is made of aluminum alloy, the filter screen 54 is made of stainless steel mesh, and the sealed bearing is made of high carbon chromium bearing steel.

[0048] The drive unit 53 includes a sealed housing 531 fixedly mounted on the centrifuge cylinder 31 and communicating with the heat exchange coil 22. A fan housing 5 is fixedly mounted on the upper end of the sealed housing 531. The bottom of the drive shaft 51 passes through the fan housing 5 and the sealed housing 531 and extends into the centrifuge cylinder 31. Vertical shaft impellers 532 are provided inside both the sealed housing 531 and the centrifuge cylinder 31. The vertical shaft impellers 532 are fixedly mounted on the drive shaft 51 and correspond to the airflow. No additional external power is required to drive the fan; the equipment's own airflow is used for propulsion, saving energy consumption and further enhancing the equipment's eco-friendly and energy-saving characteristics. The sealing housing 531 is fixedly installed on the centrifuge tube 31 and communicates with the heat exchange coil 22. The bottom of the drive shaft 51 extends through the fan housing 5 and the sealing housing 531 into the centrifuge tube 31. The vertical shaft impeller 532 is fixedly mounted on the drive shaft 51 and corresponds to the airflow. When the steam in the heat exchange coil 22 flows into the sealing housing 531, and when the airflow in the centrifuge tube 31 flows, it will impact the vertical shaft impeller 532, causing the vertical shaft impeller 532 to rotate, which in turn drives the drive shaft 51 to rotate, providing rotational power for the fan impeller 52.

[0049] The sealing housing 531 is made of 304 stainless steel, and the vertical shaft impeller 532 is made of aluminum alloy.

The power supply is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0051] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0052] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.
