Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating device technology, and in particular to a modular high-efficiency gas heating device. Background Technology
[0002] Gas fuels are a general term for gaseous fuels that can burn and release heat for use by residents and industrial enterprises. There are many types of gas fuels, mainly including natural gas, manufactured gas, liquefied petroleum gas, biogas, and coal gas. Existing heating devices require the efficient heating of gases or liquids using the heat generated during combustion.
[0003] Although existing modular high-efficiency gas heating devices adopt a parallel structure of multiple independent combustion and heat exchange modules, each module can operate independently or work in concert, the current shortcoming is that they cannot recover and utilize the waste heat of the heating device. This results in unnecessary waste of the heating device's thermal energy resources, which is detrimental to the company's production efficiency in the long run.
[0004] Therefore, to address the problem that existing heating devices cannot recover and utilize waste heat, a modular high-efficiency gas heating device can be designed. By installing a waste heat recovery device within the heating device, excess heat can be recovered and utilized again through water heating, thereby improving resource utilization. Utility Model Content
[0005] In order to overcome the problem that existing heating devices cannot recover and utilize waste heat.
[0006] The technical solution of this utility model is as follows: a modular high-efficiency gas heating device, including a protective frame, a gas storage tank placed on the inner side of the bottom of the protective frame, a gas supply pipe fixedly connected to the top of the gas storage tank, an inlet pipe fixedly connected to one end of the gas supply pipe, a gas box fixedly connected to the port of the inlet pipe, multiple sets of gas outlets installed on the top of the gas box, an outer shell provided on one side of the gas storage tank, the outer shell fixedly placed on the inner side of the bottom of the protective frame, an inner shell fixedly connected inside the outer shell, a first chamber provided between the outer shell and the inner shell, the first chamber being arranged in a ring, a port opened on the top of the outer shell, a water inlet pipe fixedly connected to the port, a valve installed inside the water inlet pipe, a port opened on the side wall of the outer shell, a water outlet pipe fixedly connected to the port, a valve installed inside the water outlet pipe, a heat-conducting base plate provided above the multiple sets of gas outlets, a heat-conducting vertical plate fixedly connected to the top of the heat-conducting base plate, the heat-conducting vertical plate fixedly connected to the inside of the inner shell, and multiple sets of heat dissipation fins installed on the outer side of the heat-conducting vertical plate.
[0007] Preferably, by operating the pulse igniter, the gas from multiple gas outlets is ignited. The flame of the burning gas heats the heat-conducting base plate, which then transfers the heat to the heat-conducting vertical plate. The vertical plate then transfers the heat to multiple sets of heat dissipation fins, which are evenly distributed in the second chamber. This allows for rapid heating of the gas entering the second chamber. The gas enters the second chamber through the inlet pipe and, after heating, exits through the outlet pipe, thus achieving the effect of heating the gas. When the heat in the second chamber dissipates outward from the side wall of the inner shell, water is injected into the first chamber through the water inlet pipe. This transfers the dissipated heat to the water in the first chamber, heating it into hot water for supply to other areas. This achieves the effect of waste heat recovery and utilization, reduces natural heat loss, and improves resource utilization.
[0008] Preferably, a pulse igniter is installed on the side wall of the housing, with the port of the pulse igniter aligned with the gas outlet.
[0009] Preferably, the inner shell has a second chamber inside, and multiple sets of heat dissipation fins and heat-conducting vertical plates are distributed in the second chamber.
[0010] Preferably, an air inlet pipe is fixedly connected to the side of the second chamber, and the air inlet pipe passes through the first chamber and the outer shell.
[0011] Preferably, an exhaust pipe is fixedly connected to the top of the second chamber, and the exhaust pipe passes through the outer shell.
[0012] Preferably, a protective cover is provided on the top of the protective frame, and an L-shaped connecting block is welded to the side of the protective cover. A semi-ring is welded to the bottom of the L-shaped connecting block, and a square padlock is hung on the inner side of the semi-ring.
[0013] Preferably, a fixing block is welded to the side of the protective frame, and a limiting slot is opened inside the fixing block. The limiting slot is slidably inserted into the L-shaped connecting block, and an inner groove is opened at the bottom of the limiting slot, allowing the semi-ring to pass through.
[0014] The beneficial effects of this utility model are:
[0015] This modular high-efficiency gas heating device uses a pulse igniter to ignite gas from multiple gas outlets. The flames from the combustion heat the heat-conducting base plate, which then transfers the heat to the heat-conducting vertical plates. These vertical plates then transfer the heat to multiple sets of heat dissipation fins, which are evenly distributed within the second chamber. This allows for rapid and efficient heating of the gas entering the second chamber. The gas enters the second chamber through an inlet pipe and exits through an outlet pipe after heating. As heat dissipates from the side wall of the inner shell from the second chamber, water is injected into the first chamber through a water inlet pipe. This transfers the dissipated heat to the water in the first chamber, heating it to hot water for other uses. This achieves waste heat recovery and utilization, reducing natural heat loss and improving resource utilization.
[0016] This modular high-efficiency gas heating device features a locking mechanism that allows the protective cover to be locked onto the protective frame. Two sets of L-shaped connecting blocks are inserted into two sets of fixing blocks, allowing two semi-rings to pass through slots at the bottom of the fixing blocks. This enables the installation of padlocks, locking the protective cover to the top of the protective frame. This prevents the heating device and gas tank from being easily damaged by others, thus protecting the equipment and reducing the risk of vandalism. Attached Figure Description

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figures 1-5 This utility model provides an embodiment: a modular high-efficiency gas heating device, including a protective frame 1, a gas storage tank 2 placed inside the bottom of the protective frame 1, a gas supply pipe 3 fixedly connected to the top of the gas storage tank 2, a gas inlet pipe 4 fixedly connected to one end of the gas supply pipe 3, a gas box 5 fixedly connected to the end of the gas inlet pipe 4, multiple gas outlets 6 installed on the top of the gas box 5, an outer shell 8 provided on one side of the gas storage tank 2, the outer shell 8 fixedly placed inside the bottom of the protective frame 1, and an inner shell 10 fixedly connected inside the outer shell 8. A first chamber 9 is provided between the outer shell 8 and the inner shell 10. The first chamber 9 is arranged in a ring. The top of the outer shell 8 has an opening, and a water inlet pipe 11 is fixedly connected to the opening. A valve is installed inside the water inlet pipe 11. The side wall of the outer shell 8 has an opening, and a water outlet pipe 12 is fixedly connected to the opening. A valve is installed inside the water outlet pipe 12. A heat-conducting base plate 13 is provided above the multiple sets of air outlets 6. A heat-conducting vertical plate 14 is fixedly connected to the top of the heat-conducting base plate 13. The heat-conducting vertical plate 14 is fixedly connected to the inner shell 10. Inside, multiple sets of heat dissipation fins 15 are installed on the outer side of the heat-conducting vertical plate 14. The gas storage tank 2 is used to store gas, which can be natural gas or liquefied coal gas. The gas in the gas storage tank 2 is transported to the gas inlet pipe 4 through the gas supply pipe 3, and then to the gas box 5 through the gas inlet pipe 4. Finally, it is released through multiple sets of gas outlets 6, and then ignited by the pulse igniter 7 to burn and heat. The heating device is provided with an outer shell 8 and an inner shell 10, and a first chamber 9 is formed between the outer shell 8 and the inner shell 10. This allows the first chamber 9 to be filled with water. It can cover the inner shell 10, thereby fully absorbing the waste heat generated by the inner shell 10. The water inlet pipe 11 is used to inject water into the first chamber 9. After the water inside is heated to a certain temperature, it is discharged through the water outlet pipe 12. This allows the waste heat to be recovered and reused. The heat of combustion is absorbed by the heat-conducting base plate 13 and then transferred to the heat-conducting vertical plate 14. It is then dissipated into the second chamber 16 through multiple sets of heat dissipation fins 15. This can heat the gas in the second chamber 16, thereby achieving the effect of heating the gas.
[0025] Please see Figure 2 , Figure 3 In this embodiment, a pulse igniter 7 is installed on the side wall of the outer shell 8, and the port of the pulse igniter 7 is aligned with the gas outlet 6; a second chamber 16 is opened inside the inner shell 10, and multiple sets of heat dissipation fins 15 and heat-conducting vertical plates 14 are distributed in the second chamber 16; an air inlet pipe 17 is fixedly connected to the side of the second chamber 16, and the air inlet pipe 17 passes through the first chamber 9 and the outer shell 8; an air outlet pipe 18 is fixedly connected to the top of the second chamber 16, and the air outlet pipe 18 passes through the outer shell 8. The pulse igniter 7 ignites the gas through pulse ignition. The gas to be heated is injected into the second chamber 16 through the air inlet pipe 17. After heating is completed, the gas is discharged through the air outlet pipe 18, thereby achieving the effect of heating the gas.
[0026] Please see Figure 4 , Figure 5 In this embodiment, a protective cover plate 19 is provided on the top of the protective frame 1, and an L-shaped connecting block 20 is welded to the side of the protective cover plate 19. A semi-ring 21 is welded to the bottom of the L-shaped connecting block 20, and a square and round padlock 22 is hung on the inner side of the semi-ring 21. A fixing block 23 is welded to the side of the protective frame 1. A limiting slot 24 is opened inside the fixing block 23. The limiting slot 24 is slidably inserted into the L-shaped connecting block 20. An inner groove is opened at the bottom of the limiting slot 24, allowing the semi-ring 21 to pass through. The protective cover plate 19 is used to cover the protective frame 1, so that the entire heating device forms a protective frame, making it impossible for people to directly damage the heating device. The square and round padlock 22 is hung on the semi-ring 21, so that the L-shaped connecting block 20 cannot be separated from the fixing block 23, thus achieving the effect of locking the protective cover plate 19.
[0027] During operation, the pulse igniter 7 ignites the gas from multiple gas outlets 6, and the flames from the combustion gas heat the heat-conducting base plate 13. The heat generated by the heat-conducting base plate 13 is then transferred to the heat-conducting vertical plate 14, which in turn transfers the heat to multiple heat dissipation fins 15. These fins are evenly distributed within the second chamber 16, allowing for rapid heating of the gas introduced into the second chamber 16. The gas in the second chamber 16 enters through the inlet pipe 17 and is then discharged through the outlet pipe 18 after heating. This achieves the effect of heating the gas. When the heat in the second chamber 16 dissipates outward from the side wall of the inner shell 10, water is injected into the first chamber 9 through the water inlet pipe 11. This transfers the dissipated heat to the water in the first chamber 9, heating it into hot water for other uses. This achieves waste heat recovery and utilization, reduces natural heat loss, and improves resource utilization.
[0028] Through the above steps, by installing a waste heat recovery device in the heating device, excess heat can be recovered and reused through water heating, thereby improving the utilization rate of resources. This solves the problem that existing heating devices cannot recover and reuse waste heat.
