Description

Technical Field

[0001] This utility model belongs to the technical field of furnace heating equipment, specifically a heat storage chimney radiator and its gasification furnace. Background Technology

[0002] Heating stoves play a vital role in residential and commercial buildings, especially in cold regions. The primary function of heating stoves is to provide comfortable indoor temperatures through various heating methods, thereby improving the comfort and quality of life of residents. With technological advancements, the types and technologies of heating stoves are constantly evolving to meet modern demands for energy efficiency, environmental friendliness, and ease of use.

[0003] Traditional furnaces use flue gas for heating, but the efficiency of heating with flue gas is too low, and a large part of the heat of the flue gas is wasted, resulting in a waste of thermal energy. In addition, the poor ventilation of many furnaces greatly affects the combustion efficiency. To address this defect, a heat storage chimney radiator and its gasification furnace were invented. Utility Model Content

[0004] To address the problems of low thermal energy utilization and low combustion efficiency in furnaces, this utility model provides a heat storage chimney radiator and its gasification furnace.

[0005] This utility model is achieved through the following technical solution.

[0006] On the one hand, this utility model provides a multifunctional gasifier including a box body, an outer tube and an inner tube are provided inside the box body, the outer tube and the inner tube pass through and extend out of the box body, the upper and lower parts of the inner tube are connected to the outer wall of the outer tube through a connecting sleeve; the lower end of the inner tube is connected to the heating mechanism.

[0007] At least one water pipe runs through both the internal and external pipes.

[0008] The upper part of the external pipe is connected to the second ventilation pipe.

[0009] The lower part of the outer pipe is connected to the conveying mechanism.

[0010] The heat generated by the heating mechanism enters the box through the internal pipe, and the heat energy is absorbed and utilized by the water pipe. At the same time, the external pipe and the conveying mechanism transfer the heat generated by the heating mechanism to different heating equipment, thereby improving the heat utilization rate.

[0011] A further improvement of this invention is that the water pipes are distributed horizontally in a crisscross pattern, which enables rapid heat absorption and thus improves the efficiency of heat utilization.

[0012] A further improvement of this utility model is that the conveying mechanism includes at least one extension pipe, the inlet of which is connected to the lower part of the outer pipe and the inlet of the extension pipe is detachably connected to the outer pipe, so as to transfer heat out through the extension pipe and thus realize the heating of the place that needs heating.

[0013] A further improvement of this utility model is that the extension tube includes a lower tube, a vertical tube, and a rotating tube connected in sequence, and the vertical tube is sleeved in a limiting ring. The limiting ring is detachably connected to the box body. The extension tube is fixed by the limiting ring, thereby preventing the heated extension tube from causing harm to people around it.

[0014] A further improvement of this utility model is that a second ventilation pipe is installed on the part of the outer pipe located above the box body. The second ventilation pipe connects the gap between the inner pipe and the outer pipe. A second blower is installed on the end of the second ventilation pipe away from the inner pipe, and gas is blown into the gap between the inner pipe and the outer pipe through the blower.

[0015] On the other hand, this utility model provides a gasification furnace, including the above-mentioned heat storage chimney radiator and heating mechanism. The heating mechanism includes a furnace body, which includes a combustion section, a ventilation section and a feeding section. Multiple ventilation boxes are provided on the sides of the feeding section and the combustion section. The ventilation boxes are hollow inside, and the side walls of the feeding section and the combustion section located inside the ventilation boxes are provided with through holes. The ventilation boxes, the ventilation section and the feeding section are interconnected, and the combustion effect of the material in the combustion section is improved through the ventilation boxes.

[0016] A further improvement of this utility model is that the ventilation section is located below the feeding section, and the ventilation section is provided with ventilation holes.

[0017] A further improvement of this utility model is that an upper cover is detachably connected to the ventilation section, and an intermediate tube is fixedly installed on the upper cover. The lower end of the inner tube is connected to the intermediate tube, and the heat generated by the combustion section is sent into the inner tube through the intermediate tube, thereby realizing the upward transfer of heat and preventing the leakage of flue gas.

[0018] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0019] (1) This invention achieves efficient heat recovery and reduces waste. The heated gas flows through the internal pipe via the heating mechanism, first heating its inner wall. The main heat is conducted through the internal pipe wall to the air in the gap between the internal and external pipes, heating this air for heating purposes. The water pipe running through the internal and external pipes directly contacts the high-temperature gas inside the internal pipe and / or the pipe wall, as well as the heated air in the interlayer, efficiently absorbing residual heat from the exhaust gas that might otherwise be directly discharged through the chimney and heat lost from the pipe wall. This significantly reduces heat loss with exhaust gas emissions, improves the overall thermal efficiency of the entire heating system, and results in significant energy savings.

[0020] (2) The design of integrating the heat source exhaust gas channel (internal pipe), fresh air heating channel (interlayer), and heat storage unit (water pipe) into a box and nested double pipe structure saves space, simplifies system layout, and facilitates installation and maintenance.

[0021] (3) The invention is equipped with a ventilation box. The internal air in the ventilation box located at the through hole in the furnace wall is heated and rises at the rear of the furnace body and is discharged from the top area of ​​the furnace body. At the same time, the opening (vent) of the ventilation box will continuously draw in cooler external air, thus improving ventilation and greatly increasing the combustion efficiency inside the furnace.

Detailed Implementation

[0033] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0034] Example 1.

[0035] As attached Figure 1 ~Appendix Figure 6 As shown, this utility model discloses a heat storage type chimney radiator, including a water tank 4, an outer pipe 501 and an inner pipe 502 installed in the water tank 4, the inner pipe 502 being located inside the outer pipe 501, the output end of the heating mechanism 1 being connected to the inner pipe 502, the heating mechanism 1 sending heating gas into the inner pipe 502, and a conveying mechanism 3 being installed on the water tank 4, the conveying mechanism 3 being connected to the outer pipe 501.

[0036] As attached Figure 2 ~Appendix Figure 7 As shown, this utility model discloses a water tank 4 and a water pipe 507. The water tank 4 includes a tank body 401, an outer pipe 501 and an inner pipe 502 that pass through and extend out of the tank body 401, and the upper part of the inner pipe 502 is connected to the outer wall of the outer pipe 501 through a connecting sleeve 503.

[0037] The connecting sleeve 503 can be detachably sleeved with the outer pipe 501 and / or the inner pipe 502, or it can be fixedly connected, such as by welding. The connecting sleeve 503 is a hollow annular disc, with one side sleeved with the outer pipe 501 and the other side sleeved with the inner pipe 502. When welding is used, to ensure the stability of the entire device, vertically distributed triangular fixing plates can be added at the connection between the connecting sleeve 503 and the outer pipe 501 and / or the inner pipe 502. One or more water pipes 507 are provided, each penetrating both the inner pipe 502 and the outer pipe 501. The water pipes 507 are distributed in a staggered pattern on the outer surface of the outer pipe 501. They can be used horizontally or at an angle, and the specific number and thickness depend on the thickness and height of the inner pipe. By installing water pipes inside the outer pipe 501 and the inner pipe 502, better heat exchange between hot air and water can be achieved, thereby improving heat utilization.

[0038] The two ends of the water pipe 507 are located inside the box 401. A water inlet 403 is fixedly installed on the upper part of the box 401. A water storage tank 404 is provided inside the box 401. Water is injected into the water storage tank 404 through the water inlet 403. The water in the water storage tank 404 flows into the water pipe 507. A drain valve 402 is installed on the side of the box 401. The drain valve 402 is connected to the water storage tank 404.

[0039] An air blowing hole 506 is provided on the outer surface of the outer tube 501. The air blowing hole 506 can be circular. The inner wall of the air blowing hole 506 is connected to the ventilation tube 504. The gap between the outer tube 501 and the inner tube 502 is connected to the second ventilation tube 504. A second blower 505 is installed at the end of the second ventilation tube 504 away from the inner tube 502. Gas is blown into the gap between the inner tube 502 and the outer tube 501 through the second blower 505.

[0040] The second blower 505 can be a suitable model of miniature fan. When in use, the second ventilation pipe 504 can be fixedly connected to the miniature fan. When needed, the second ventilation pipe 504 can be inserted into the gap between the outer pipe 501 and the inner pipe 502 to blow air. When not needed, the whole thing can be removed for easy placement.

[0041] To ensure the airtightness of the water tank 4 and the external pipe 501, the lower part of the external pipe 501 is connected to the conveying mechanism 3, a sealing ring 405 is installed inside the water storage tank 404, and the external pipe 501 is installed on the inner wall of the sealing ring 405.

[0042] As attached Figure 3 ~Appendix Figure 6As shown, this utility model discloses a conveying mechanism 3. Multiple conveying mechanisms 3 can be configured as needed. Each conveying mechanism 3 includes a lower pipe 305, a vertical pipe 301, and a rotating pipe 302 connected sequentially. The vertical pipe 301 is fitted inside a limiting ring 303, which is detachably connected to the housing 401 via fixing bolts 304. The inlet of the lower pipe 305 communicates with the gap between the outer pipe 501 and the inner pipe 502. The vertical pipe 301 is installed at the lower part of the lower pipe 305, and the rotating pipe 302 is rotatably installed on the upper part of the vertical pipe 301. Each rotating pipe 302 is connected to other heating equipment via a pipe. The lower pipe 305, vertical pipe 301, and rotating pipe 302 are all rotatable, facilitating airflow adjustment. In use, the rotating pipe 302 can be extended or connected to other pipes, allowing hot air to be introduced to the desired area as needed, thus expanding the heating area. In addition, when the rotating tube 302 is transported over a long distance, it is fixed to other supports by connecting ropes or wall gaps, which also helps to balance the entire device.

[0043] The second blower 505 actively blows cold air into the gap between the inner pipe 502 and the outer pipe 501, achieving forced convection. As the cold air flows through the gap, it is fully heated by the high-temperature outer wall of the inner pipe 502. The inner pipe 502 directly conducts heat from the heat source, ensuring thorough heat exchange and high thermal efficiency. This generates a large amount of high-temperature hot air, which is then transported to the heating equipment through the lower pipe 305, vertical pipe 301, and rotating pipe 302, improving the heating effect. The heating equipment can be located outside the heating mechanism, allowing for more flexible system layout.

[0044] As attached Figure 9 As shown, E represents the flow direction of the heating gas from heating mechanism 1, and D and F represent the flow directions of the gas blown in by the second blower 505. The gas blown in by the second blower 505 enters the gap between the inner pipe 502 and the outer pipe 501 through the second ventilation pipe 504, and then flows out through the two lower pipes 305 respectively. The two paths exchange heat through the pipe walls at the interlayer, and the water pipe 507 runs through the core heat exchange area of ​​both paths. The airflow path design is reasonable, reducing short circuits and ensuring that the cold air has sufficient contact time and area with the hot surface (inner pipe wall) for effective heat exchange.

[0045] The working principle of this embodiment is as follows.

[0046] (1) Before operation, water is injected into the water tank 404 through the water inlet 403. The water flows into the water pipe 507. The heating mechanism 1 is started. The heating gas generated by the heating mechanism 1 enters the inner pipe 502, thereby heating the inner wall of the inner pipe 502. The gas in the gap between the inner pipe 502 and the outer pipe 501 is heated through the inner pipe 502. A portion of the heat is absorbed by the water in the water pipe 507, reducing the waste of heat.

[0047] (2) The second blower 505 is started. The second blower 505 blows gas into the gap between the inner pipe 502 and the outer pipe 501 through the second ventilation pipe 504. The heated air in the gap between the inner pipe 502 and the outer pipe 501 passes through the lower pipe 305, the vertical pipe 301 and the rotating pipe 302 in sequence, and enters the heating equipment to heat the room.

[0048] The heat storage process of this invention is as follows: During the operation of the heating mechanism 1, the water in the water pipe 507 continuously absorbs waste heat from the internal pipe 502 and part of the heat from the hot air in the jacket, causing the water temperature to rise and storing the thermal energy. The heat release process is as follows: When the heating mechanism 1 stops operating (or is in a state of incomplete combustion), the water that has stored heat can slowly release the heat through natural convection or auxiliary circulation, continuing to heat the jacket air or providing direct heating, thus extending the heating time and providing a more stable and continuous room temperature.

[0049] The flue gas from the internal pipe 502 is discharged through the external pipe. A reasonable layout can be adopted for the external pipe to minimize the heat of the discharged flue gas and retain more heat before it is discharged.

[0050] Example 2.

[0051] As attached Figure 1 ~Appendix Figure 2 As shown, the heating mechanism 1 includes a furnace body 101, which includes a combustion section 1011, a ventilation section 1012, and a feeding section 1013. Multiple ventilation boxes 102 are provided on the sides of the feeding section 1013 and the combustion section 1011. The ventilation boxes 102 are hollow inside and have through holes on the sides. The ventilation boxes 102 adopt a shell mechanism. The shell is fixed to the outer wall of the combustion section 1011 or the feeding section 1013, and the lower part of the shell is open while the rest is closed. Several through holes are provided on the outer wall of the combustion section 1011 or the feeding section 1013 located inside the shell.

[0052] As one embodiment, the ventilation box can adopt the following structure: the ventilation box 102 has an opening at the bottom and is closed at the top, forming a chimney-like structure. High-temperature air (or flue gas) inside the furnace wall through-holes is heated and rises at the rear of the furnace body, exiting from the top area. Simultaneously, the opening at the bottom of the shell continuously draws in cooler outside air. Therefore, cool air enters from the bottom, flows over the high-temperature furnace wall surface (through the through-holes), absorbs heat, and becomes hot air, exiting from the top, creating a "chimney effect" that can greatly improve the combustion efficiency within the furnace body 101.

[0053] Furthermore, a highly efficient and continuous cooling air duct is formed outside the furnace wall in the critical high-temperature areas (combustion section 1011 / feeding section 1013), actively removing heat and significantly reducing the wall temperature, which can protect the furnace structure and extend the equipment's lifespan. At the same time, the shell protects the through holes on the furnace wall from entering directly into the through holes, preventing dust, debris, water, or splashes that may occur during operation, thus preventing blockage or corrosion.

[0054] Ventilation box 102, ventilation section 1012, and feeding section 1013 are interconnected. Ventilation section 1012 is located below feeding section 1013. Rotating cover 106 is rotatably installed on feeding section 1013. Ventilation section 1012 is provided with ventilation holes. Upper cover 107 is detachably connected to ventilation section 1012. Intermediate tube 109 is fixedly installed on upper cover 107. Intermediate tube 109 is slidably installed on inner wall of inner tube 502. Lower part of inner tube 502 is interconnected with intermediate tube 109.

[0055] To ensure the stability of the thermal storage chimney radiator, the height at which the internal tubes are inserted into or fitted onto the intermediate tube 109 is rationally designed, and high-strength steel is preferred as the material. Furthermore, fixing devices can be installed at the top of the internal tubes as needed to assist in maintaining overall stability.

[0056] A slide plate 104 is slidably mounted on the ventilation section 1012. A circular through hole is provided on the side of the slide plate 104. A first ventilation pipe 108 is slidably mounted on the inner wall of the circular through hole on the side of the slide plate 104. A first blower 105 is installed at the end of the first ventilation pipe 108 away from the ventilation section 1012. A support rod 103 is symmetrically fixedly mounted on both sides of the ventilation section 1012 and the combustion section 1011. A discharge plate is provided at the connection between the feeding section 1013 and the ventilation section 1012.

[0057] The connection between the first ventilation pipe 108 and the first blower device 105 can adopt a similar structure to the second blower device 505 and the second ventilation pipe 504. When in use, the first ventilation pipe 108 is inserted into the circular through hole on the side of the slide plate 104, and the first ventilation pipe 108 is tilted upward. The blower promotes the combustion of fuel inside the furnace. When the fuel inside the furnace has burned to a certain extent, the blower volume of the first blower device 105 can be reduced, or the first ventilation pipe 108 and the first blower device 105 can be removed to stop ventilation. The furnace body 101 continues to burn through the through hole.

[0058] The working principle of this embodiment is as follows: Before operation, the rotating cover 106 is opened, and then the combustible material is fed into the combustion section 1011 through the feeding section 1013. After the combustible material is ignited, the first blower 105 is started. The first blower 105 sends air into the combustion section 1011 through the first ventilation pipe 108, thereby increasing the combustion effect. The heat of the flue gas generated by the combustion section 1011 is sent into the inner pipe 502 through the intermediate pipe 109.

[0059] In addition, the ventilation box 102 has another application structure in which ventilation holes are provided on the side. The ventilation box 102 is connected to the combustion section 1011 and the feeding section 1013 through the ventilation holes provided on the side. The ventilation box 102 provides air to the combustion section 1011 and the feeding section 1013, thereby improving the combustion effect of the combustibles in the combustion section 1011.

[0060] Example 3

[0061] The heating mechanism 1 can also be used independently. Specifically, the upper cover 107 and the middle tube 109 are removed, and the kettle is placed on top of the combustion section 1011.

[0062] The working principle of this embodiment is as follows.

[0063] Open the rotating cover 106, fill the kettle with water, and then feed the combustible material into the combustion section 1011 through the feed section 1013. After the combustible material is ignited, the first blower 105 is activated. The first blower 105 sends air into the combustion section 1011 through the first ventilation pipe 108, thereby increasing the combustion effect. The flame generated by the combustion of the combustible material in the combustion section 1011 heats the water in the kettle.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
