Description

Technical Field

[0001] This utility model relates to the field of industrial boiler technology, and more specifically, to an industrial boiler with improved evaporation efficiency. Background Technology

[0002] As an energy conversion device, the core function of a boiler is to convert the chemical energy in fuel into thermal energy, thereby generating high-temperature steam. Its structure originates from the dual structure of a water-containing container and a combustion site, and it is widely used in industrial fields such as thermal power plants, ships, and mining enterprises. In actual operation, evaporation efficiency is the core indicator for measuring boiler performance. By optimizing combustion control, heat transfer path, and evaporation chamber design, the conversion rate of heat energy to steam can be improved, directly affecting the boiler's production efficiency and energy consumption. Therefore, it is necessary to design an industrial boiler that improves steam efficiency and avoids heat transfer losses.

[0003] However, existing industrial boilers that improve steam efficiency typically rely on heat conduction through the pipe walls to evaporate the water source, resulting in the contact surface with flue gas being only the outer surface of the pipes, thus limiting the heat conduction area. At the same time, since particles in the flue gas adhere to the pipe surface, not only does it increase thermal resistance, but it also exacerbates the attenuation of heat transfer, causing the steam production efficiency to decrease linearly with operating time. This further reduces the uniformity and stability of heat exchange, ultimately limiting the improvement of the overall thermal efficiency of the boiler and reducing steam thermal efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an industrial boiler with improved evaporation efficiency to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An industrial boiler for improving evaporation efficiency includes: a boiler body; a feeding assembly disposed at the bottom of one end of the boiler body; a combustion chamber disposed at the bottom of the boiler body and connected to the feeding assembly; a slag discharge box disposed at the bottom of one end of the combustion chamber; a water tank disposed at the bottom of the other end of the boiler body; a steam conveying assembly disposed inside the boiler body and connected to the water tank to increase the contact area with flue gas; a cleaning mechanism disposed outside the steam conveying assembly for cleaning the steam conveying assembly; a control panel disposed outside the boiler body; and a flue gas discharge pipe extending through the top of the other end of the boiler body.

[0008] Furthermore, to increase the heat exchange rate, the staggered arrangement of heat-conducting plates increases the contact area with the flue gas, thereby increasing the heat conduction area and constructing a multi-channel turbulent heat exchange interface. This significantly improves the heat exchange rate per unit area. The steam delivery assembly includes: a water pipe located at the bottom inner part of the boiler body and connected to a water tank; several evaporation pipes located at the top of the water pipe and connected to it; a water level sensor located at the top inner part of the evaporation pipes; several heat-conducting plates located on the outside of the evaporation pipes; and a steam discharge pipe located at the top of the evaporation pipes and connected to them. The heat-conducting plates are staggered and distributed circumferentially on the outside of the evaporation pipes.

[0009] Furthermore, to avoid increased thermal resistance and decreased heat transfer efficiency due to ash accumulation, the system can periodically and actively remove ash from the surfaces of the heat-conducting plates, evaporator tubes, and filter cartridges through the extension and contraction of the electric telescopic rod, maintaining a clean heat exchange interface and reducing downtime maintenance costs. Simultaneously, by pre-intercepting flue gas particles, it can further reduce the adhesion of these particles to the evaporator tube surface, significantly improving the boiler's steam efficiency during continuous operation. The cleaning mechanism includes a connecting frame located at the bottom outside the evaporator tubes, a filter cartridge located outside the connecting frame, and a rotating frame located at the top of the filter cartridge. A connecting rod is located at the bottom of the rotating frame, between the filter cartridge and the evaporator tube, and a series of connecting rods are installed on the side of the connecting rod closest to the evaporator tube. A first cleaning rod is fitted with a heat-conducting plate, and a second cleaning rod is fitted with the inner wall of the filter cylinder on the other side of the connecting rod. A third cleaning rod is fitted with the outer side of the filter cylinder and connected to the rotating frame. A gear ring is connected to the top of the rotating frame, and a rack is meshed on one side of several gear rings. A limit frame is provided on the outer side of the rack, and a limit groove is opened in the middle of the limit frame to fit with the rack. A connecting block penetrating the boiler body is provided inside the limit groove. An electric telescopic rod is provided on one side of the connecting block and on the outer side of the boiler body. A protective box connected to the boiler body is provided on the outer side of the electric telescopic rod. The gear ring and the evaporator tube are connected by a bearing. The length of the limit groove is less than the length of the rack. The limit frame is connected to the boiler body.

[0010] The beneficial effects of this utility model are as follows:

This invention, through the coordinated arrangement of the boiler body, feeding assembly, combustion chamber, ash discharge chamber, water tank, steam conveying assembly, cleaning mechanism, and control panel, not only significantly improves the overall efficiency of the boiler in industrial steam production; but also, under the action of the staggered and circumferentially distributed heat-conducting plates, further increases the contact area with flue gas, improving heat transfer efficiency. At the same time, it periodically scrapes away the ash accumulation on the surface of the heat-conducting plates, evaporator tubes, and filter cylinders, maintaining the cleanliness of the heat exchange interface, avoiding the increase in thermal resistance and the decrease in heat transfer efficiency caused by ash accumulation, and improving the steam efficiency of the boiler during long-term operation.

[0012] 2. The present invention, through the steam conveying component, can increase the contact area with flue gas under the action of staggered heat-conducting plates, thereby increasing the heat conduction area and constructing a multi-channel turbulent heat exchange interface, thus significantly improving the heat exchange rate per unit area.

[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, an industrial boiler with improved evaporation efficiency is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-11As shown, an industrial boiler for improving evaporation efficiency according to an embodiment of the present invention includes: a boiler body 1; a feeding assembly 2 disposed at the bottom of one end of the boiler body 1; a combustion chamber 3 disposed at the bottom of the boiler body 1 and connected to the feeding assembly 2; a slag discharge box 4 disposed at the bottom of one end of the combustion chamber 3; a water tank 5 disposed at the bottom of the other end of the boiler body 1; a steam conveying assembly 6 disposed inside the boiler body 1 and connected to the water tank 5, for increasing the contact area with flue gas; a cleaning mechanism 7 disposed outside the steam conveying assembly 6 for cleaning the steam conveying assembly 6; a control panel 8 disposed outside the boiler body 1; and a flue gas discharge pipe 101 penetrating through the top of the other end of the boiler body 1.

[0031] In one embodiment, the steam conveying assembly 6 includes: a water supply pipe 601 disposed at the inner bottom of the boiler body 1 and connected to the water tank 5; a plurality of evaporation pipes 602 disposed at the top of the water supply pipe 601 and connected to the water supply pipe 601; a water level sensor 603 disposed at the inner top of the evaporation pipes 602; a plurality of heat-conducting plates 604 disposed on the outer side of the evaporation pipes 602; and a steam discharge pipe 605 disposed at the top of the plurality of evaporation pipes 602 and connected to the plurality of evaporation pipes 602. The plurality of heat-conducting plates 604 are arranged alternately and circumferentially on the outer side of the evaporation pipes 602. The alternating arrangement of the heat-conducting plates 604 increases the contact area with the flue gas, thereby increasing the heat conduction area and constructing a multi-channel turbulent heat exchange interface, thus significantly improving the heat exchange rate per unit area.

[0032] The working principle of the steam delivery assembly 6 is as follows: The heat-conducting plates 604, arranged in a staggered and circumferential pattern on the outside of the evaporator tube 602, increase the contact area with the flue gas. The circumferential distribution also creates turbulence between the flue gas and the tube wall during flow, enhancing the heat transfer coefficient. The high-temperature flue gas generated by the combustion chamber 3 surrounds the evaporator tube, and the heat is efficiently transferred to the water inside the tube via the heat-conducting plates. The water level sensor 603 monitors the water level in the evaporator tube 602 in real time and transmits the monitored water level signal to the control panel 8. When the detected water level signal is lower than the preset minimum water level, the submersible pump in the water tank 5 is activated via the control panel 8 to deliver water to the water supply pipe 601, which then supplies water to the evaporator tube 602. When the detected water level in the evaporator tube 602 reaches the maximum water level, the submersible pump is stopped via the control panel 8 to ensure continuous heating and evaporation. Steam is output through the top steam exhaust pipe 605, forming a closed evaporation cycle.

[0033] In one embodiment, the cleaning mechanism 7 includes a connecting frame 701 located at the bottom outer side of the evaporator tube 602, a filter cylinder 702 located on the outer side of the connecting frame 701, and a rotating frame 703 located at the top of the filter cylinder 702. A connecting rod 704 is located at the bottom of the rotating frame 703 between the filter cylinder 702 and the evaporator tube 602. A first cleaning rod 705, cooperating with several heat-conducting plates 604, is located on the side of the connecting rod 704 near the evaporator tube 602. A second cleaning rod 706, cooperating with the inner wall of the filter cylinder 702, is located on the other side of the connecting rod 704. A third cleaning rod 707, connected to the rotating frame 703, is located on the outer side of the filter cylinder 702. A gear ring 708 is connected to the top of the rotating frame 703. A rack 709 is meshed on one side of several gear rings 708. A limit frame 710 is located on the outer side of the rack 709. The middle of the limit frame 710 is open. A limiting groove 711 is provided to cooperate with the rack 709. A connecting block 712 penetrating the boiler body 1 is provided inside the limiting groove 711. An electric telescopic rod 713 is provided on one side of the connecting block 712 and on the outside of the boiler body 1. A protective box 714 connected to the boiler body 1 is provided on the outside of the electric telescopic rod 713. The gear ring 708 is connected to the evaporator tube 602 through a bearing. The length of the limiting groove 711 is less than the length of the rack 709. The limiting frame 710 is connected to the boiler body 1. Under the extension and contraction of the electric telescopic rod 713, it can periodically and actively remove the ash accumulation on the surface of the heat conduction plate 604, evaporator tube 602 and filter cylinder 702, maintain the cleanliness of the heat exchange interface, and reduce downtime maintenance costs. At the same time, it can also further reduce the adhesion of flue gas particles on the surface of the evaporator tube 602 by pre-intercepting flue gas particles, which greatly improves the steam efficiency of the boiler during continuous operation.

[0034] In addition, in specific applications, in order to ensure that the rack 709 can smoothly drive the gear ring 708 to rotate, and thus ensure that the gear ring 708 drives the first cleaning rod 705, the second cleaning rod 706 and the third cleaning rod 707 to rotate around the filter cylinder 702 once, the length of the rack 709 is less than the length of the water tank 5.

[0035] The working principle of the cleaning mechanism 7 is as follows: It intercepts flue gas particles through a filter cartridge 702 fitted on the outside. Based on a preset cleaning time interval, the electric telescopic rod 713 is periodically activated via the control panel 8. The electric telescopic rod 713, through its extension and retraction, drives the connecting block 712 to move within the limiting groove 711, further driving the rack 709 connected to the connecting block 712 to move left and right within the limiting groove 711. This, in turn, causes the gear ring 708 meshing with the rack 709 to rotate, thereby rotating the first rotating frame 703. This allows the first cleaning rod 705 to periodically scrape away the evaporator tube 602 and guide tube. Dust accumulates on the surface of the hot plate 604. Simultaneously, the staggered arrangement of the heat-conducting plates 604 ensures that the dust removed from the upper heat-conducting plates 604 is continuously cleaned down to the inner bottom of the boiler body 1. At the same time, the second cleaning rod 706 cleans the inner wall of the filter cylinder 702, and the third cleaning rod 707 cleans the flue gas particles intercepted on the outer side of the filter cylinder 702. This periodic scraping of dust from the surfaces of the heat-conducting plates 604, evaporator tubes 602, and filter cylinder 702 ensures a clean heat exchange interface. The flue gas exhaust pipe 101 is located at the top, forming a natural convection channel to promote flue gas discharge.

[0036] In addition, it should be noted that the above-mentioned feeding assembly 2 consists of a feeding pipe, a storage tank, a quantitative feeding assembly and a discharge pipe. The quantitative feeding assembly consists of an electric push rod, a push plate and a fixed material trough, and the outlet end of the discharge pipe is connected to one end of the combustion chamber 3. This feeding assembly 2 is existing technology and will not be elaborated on here.

[0037] In addition, it should be noted that the combustion box 3 is composed of a burner, a stepped chain conveyor assembly and a slag discharge port, and the slag discharge port is connected to the slag discharge box 4. In actual use, the slag is conveyed to the slag discharge box 4 through the stepped chain conveyor assembly. The stepped chain and the combustion box 3 are existing technologies, and will not be elaborated on here.

[0038] In addition, it should be noted that the above-mentioned slag discharge box 4 is composed of a slag collection plate and a pull-out assembly. The slag on the slag collection plate is pulled out by the pull-out assembly like a drawer for slag discharge. The pull-out assembly and the slag discharge box 4 are existing technologies and will not be elaborated on here.

[0039] In addition, it should be noted that a submersible pump is installed in the water tank 5, which can deliver water to the water pipe 601. This submersible pump is existing technology and will not be elaborated on here.

[0040] Furthermore, it should be noted that the aforementioned water level sensor 603 is a radar-based liquid level sensor. This sensor monitors the water level to ensure timely replenishment of water to the evaporator tube 602. The sensor utilizes radio wave transmission and reception to accurately measure the water level, providing stable and reliable results even in harsh environments. Specifically, the water level in the evaporator tube 602 is monitored by the liquid level sensor, and the monitored water level signal is transmitted to the control panel 8. This water level sensor 603 is existing technology and will not be elaborated upon further here.

[0041] In addition, it should be noted that the control panel 8 consists of a human-machine interface (HMI) and a programmable logic controller (PLC), and the control panel 8 is electrically connected to the feeding assembly 2, the combustion chamber 3, the slag discharge chamber 4, the water tank 5, and the cleaning mechanism 7; this control panel 8 is existing technology and will not be elaborated on further here.

[0042] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0043] In practical applications, the submersible pump in the water tank 5 is started via the control panel 8. The submersible pump delivers water to the water supply pipe 601, and the water level sensor 603 transmits the real-time water level signal to the control panel 8. When the water level signal reaches the preset maximum water level, the submersible pump in the water tank 5 stops delivering water to the water supply pipe 601 via the control panel 8. At the same time, the fuel for the boiler is added to the combustion chamber 3 through the feed pipe of the feed assembly 2, and ignited by the burner in the combustion chamber 3. Simultaneously, the slag is conveyed to the slag discharge box 4 via the stepped chain conveyor assembly. The fuel is fully combusted in the combustion chamber 3 to generate high-temperature flue gas. The flue gas flows upward from the bottom of the boiler body 1, surrounding the water supply pipe 601 and the evaporation pipe 602. Through the heat-conducting plates 604 arranged in a staggered pattern on the outside of the evaporation pipe 602, a multi-channel heat exchange interface is formed, allowing the flue gas to efficiently transfer heat to the water in the pipe under the turbulence effect. Water from the tank is continuously supplied to the evaporator tube 602 via the water supply pipe 601. An internal water level sensor 603 monitors the liquid level in real time and automatically adjusts the water inflow to ensure stable water level for heating and evaporation. After the high-temperature water vaporizes, the steam accumulates at the top of the evaporator tube 602 and is output to the subsequent steam treatment process via the steam discharge pipe 605. Flue gas particles generated during combustion are intercepted by the filter cartridge 702 to prevent ash accumulation from affecting heat transfer efficiency. Furthermore, the cleaning mechanism 7 is activated periodically. The extension and retraction of the electric telescopic rod 713 drives the rack 709 to move, causing the gear ring 708 to rotate. This causes the rotating frame 703 connected to the gear ring 708 to rotate, and drives the first cleaning rod 705, the second cleaning rod 706, and the third cleaning rod 707 to periodically scrape away ash from the surfaces of the evaporator tube 602 and the heat-conducting plate 604, ensuring a clean heat exchange interface. After heat exchange, the flue gas is naturally discharged through the top flue gas discharge pipe 101, forming a smooth flue gas flow path. Finally, the slag in the slag discharge box 4 is periodically removed and cleaned by the operators.

[0044] In summary, by utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of the boiler body 1, feeding assembly 2, combustion box 3, ash discharge box 4, water tank 5, steam conveying assembly 6, cleaning mechanism 7, and control panel 8, not only can the overall efficiency of the boiler in industrial steam production be significantly improved; but also, under the action of the staggered and circumferentially distributed heat-conducting plates 604, the contact area with flue gas is further increased, improving heat transfer efficiency. Simultaneously, the periodic scraping of ash from the surfaces of the heat-conducting plates 604, evaporator tubes 602, and filter cartridges 702 maintains the cleanliness of the heat exchange interface, preventing increased thermal resistance and decreased heat transfer efficiency due to ash accumulation, and improving the steam efficiency of the boiler during long-term operation. The steam conveying assembly 6 increases the contact area with the flue gas through the staggered heat-conducting plates 604, thereby increasing the heat conduction area and constructing a multi-channel turbulent heat exchange interface, which in turn significantly improves the heat exchange rate per unit area. The cleaning mechanism 7 periodically and actively removes the ash accumulation on the surfaces of the heat-conducting plates 604, evaporator tubes 602, and filter cartridges 702 by the extension and contraction of the electric telescopic rod 713, maintaining the cleanliness of the heat exchange interface and reducing downtime maintenance costs. At the same time, it can further reduce the adhesion of flue gas particles on the surface of the evaporator tubes 602 by pre-intercepting flue gas particles, which greatly improves the steam efficiency of the boiler during continuous operation.
