Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of boiler automation control, in particular to a boiler rapid starting device suitable for low-temperature environment. BACKGROUND

[0002] Industrial boilers are important heat power equipment in the industrial field, which meet the heat demand in the process of industrial production, heating and refrigeration, etc. The boiler rapid starting device is a key core component for realizing emergency operation and rapid heating of the boiler in low-temperature environment, and its starting efficiency, temperature control accuracy and safety protection capability directly determine the safety of boiler operation, structural durability and energy consumption control level.

[0003] At present, in the application of boiler starting in low-temperature environment, the traditional preheating starting and auxiliary ignition device have many technical bottlenecks, which seriously restrict the low-temperature starting efficiency and equipment operation safety. The traditional boiler preheating system relies on external heat sources such as electric heat tracing, has no active anti-freezing and thermal stress regulation mechanism, and the hidden troubles such as pipe freezing, component cold brittleness and steam pocket wall temperature difference exceeding the standard cannot be checked in advance. Moreover, it is easy to be disturbed by low-temperature cold wave, environmental temperature difference and equipment aging, resulting in uneven preheating temperature rise, incomplete thawing, and failure to meet the requirements of rapid starting in low-temperature environment. Moreover, the traditional starting temperature control mostly adopts pure manual or simple electronic control logic, which lacks thermal shock redundancy protection structure. When problems such as power failure, sensor element failure and heating module failure occur, local over-temperature and uncontrolled temperature rise rate are easy to occur, which violates the core principle of fault-oriented safety. At the same time, the existing part of low-temperature starting auxiliary device only relies on single preheating mode to realize passive temperature rise, and has no multi-module collaborative regulation mechanism. In the scene of cold-state rapid starting of the boiler, the response is lagged, and the environmental adaptability is insufficient. For example, the preheating fails due to the attenuation of heat source output in low temperature, the heat exchange medium leaks due to loose pipe connection in low-temperature vibration, and the ignition system accumulates frost in humid low-temperature environment, resulting in difficulty in fuel ignition. More importantly, the existing device lacks targeted low-temperature protection design. The metal pipe is easy to deform and crack under the influence of thermal stress formed by external low temperature and internal high temperature. Frequent shutdown for thawing, maintenance and repair not only greatly reduce the operation efficiency of the boiler, but also may cause safety risks such as pipe freezing, furnace explosion and incomplete combustion of fuel due to inadequate protection. Although there are a few low-temperature boiler starting auxiliary devices at present, the structure is dispersed, the linkage of each module is poor, the energy consumption is too high, and the device is not deeply coordinated with the heat exchange, combustion and temperature control system of the boiler body. Therefore, it cannot realize the integrated control of preheating temperature rise and safety protection, and cannot meet the requirements of low-temperature rapid starting and safe and stable operation of the boiler in low-temperature areas.

[0004] Therefore, we propose a boiler rapid starting device suitable for low-temperature environment to solve the problems in the above. SUMMARY

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the application will be described clearly and completely below with the accompanying drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0020] As Figures 1-2 shown, the embodiment discloses a boiler rapid starting device suitable for low temperature environment, which comprises a moving and lifting assembly 100, a steam generating assembly 200, a solution supply assembly 300 and a mixing and stirring assembly 400. The steam generating assembly 200, the solution supply assembly 300 and the mixing and stirring assembly 400 are arranged on the top of the outer wall of the moving and lifting assembly 100, and the mixing and stirring assembly 400 is arranged at the output end of the solution supply assembly 300.

[0021] This embodiment primarily addresses the numerous technical bottlenecks in traditional preheating start-up and auxiliary ignition devices used in boiler startup applications in low-temperature environments. These bottlenecks severely restrict low-temperature startup efficiency and equipment operational safety. Traditional boiler preheating systems often rely on external heat sources like electric heat tracing, lacking active antifreeze and thermal stress control mechanisms. This makes it difficult to proactively detect potential problems such as pipe freezing, component brittleness, and excessive temperature differences in the steam drum wall. Furthermore, these systems are susceptible to interference from low-temperature cold waves, ambient temperature differences, and equipment aging, leading to uneven preheating and incomplete thawing, failing to meet the rapid startup requirements in low-temperature environments. Additionally, traditional startup temperature control often employs purely manual or simplistic electronic control logic, lacking redundant thermal shock protection structures. When problems such as power outages, sensor failures, or heating module malfunctions occur, localized overheating and uncontrolled heating rates are likely to result. These issues pose risks and violate the core principle of fault-oriented safety. Furthermore, some existing low-temperature start-up auxiliary devices rely solely on a single preheating method for passive heating, lacking a multi-module collaborative control mechanism. This results in delayed response in cold-state rapid boiler start-up scenarios and insufficient environmental adaptability. For example, attenuation of heat source output at low temperatures leads to preheating failure; loose pipe connections under low-temperature vibration cause heat exchange medium leakage; and frost buildup on the ignition system in humid, low-temperature environments makes fuel ignition difficult. More importantly, existing devices lack targeted low-temperature protection designs. Metal pipes are prone to deformation and cracking under the thermal stress created by external low temperatures and internal high temperatures, requiring frequent shutdowns for thawing, maintenance, and repair. This not only significantly reduces boiler operating efficiency but may also lead to safety risks such as pipe freezing and cracking, furnace explosions, and incomplete fuel combustion due to inadequate protection. While a small number of low-temperature boiler start-up auxiliary devices exist, their structures are scattered, the modules have poor interoperability, energy consumption is too high, and they lack deep integration with the boiler's heat exchange, combustion, and temperature control systems. This prevents integrated control of preheating and safety protection, making them unsuitable for the rapid low-temperature start-up and safe, stable operation requirements of boilers in low-temperature regions.

[0022] This embodiment was completed to solve the problems of the prior art. Through the systematic coordination of various modules of the steam generating component 200, it achieves the unity of low-temperature start-up, precise preheating and safe operation. The component formed by the heating ring 203 and the heat conducting rod 204 relies on the structural design of ring heating and multi-rod uniform heating to eliminate the inherent problems of local overheating, low thermal efficiency and lag in heating at low temperatures during the heating process. The microporous membrane vapor-liquid separation component uses the dispersed filtration of hydrophobic and breathable PTFE membrane. With the help of the physical mechanism of steam pressure difference adaptive permeation and liquid surface tension blocking, it ensures that only steam is output and prevents liquid leakage, avoiding the risk of thermal shock caused by high-temperature liquid entering the furnace wall and resulting in excessive temperature difference between the inside and outside. Specifically, the first aspect involves using hot steam to preheat the furnace wall while employing a microporous membrane for vapor-liquid separation to ensure preheating efficiency and equipment safety. This invention adopts a ring heating combined with a multi-bar heat distribution structure, which uses heat-conducting rods 204 to uniformly conduct heat to the entire cavity, significantly improving heating efficiency and steam quality, ensuring steam temperature stability, and greatly reducing the risk of compound liquid decomposition caused by local overheating. Furthermore, the purely physical separation mechanism of the microporous membrane vapor-liquid separation component ensures that no liquid seeps out of the steam, and the metal mesh 213 filters out tiny impurities, avoiding thermal shock and scaling hazards to the furnace wall. At the same time, the turbulent design of the forced steam delivery by the fan allows steam to quickly fill the furnace chamber, and the aluminum foil foam insulation layer of the insulation shell 201 reduces heat loss in low-temperature environments, further improving preheating uniformity and efficiency. Secondly, by integrating functions and simplifying the structure, the steam generating component 200 improves equipment efficiency. It integrates five major functions: heating, vaporization, separation, steam delivery, and heat preservation. Through core components such as the heating ring 203, heat-conducting rod 204, microporous membrane baffle 205, and fan, it achieves efficient and streamlined steam output, significantly reducing equipment complexity and failure rate. It achieves integrated processes of steam generation, precise delivery, and heat loss control, reducing the possibility of errors caused by human intervention. The split-type insulation shell 201 and low-temperature resistant design achieve long-term heat preservation of the steam channel. The core design, which does not rely on complex algorithms and does not require frequent cleaning, gives the equipment a long lifespan and easy maintenance, perfectly adapting to the rapid start-up requirements of boilers in low-temperature areas. This invention upgrades the traditional decentralized preheating and passive protection technology for low-temperature boiler startup to an integrated preheating and safety control scheme, which can significantly improve the boiler startup efficiency, operational safety, and structural durability, meeting the stringent requirements of low-loss, high-reliability, and strong environmental adaptability for industrial and heating boilers in low-temperature areas.

[0023] according to Figures 2-4As shown, a fan motor 208 is provided on one side of the outer surface of the insulation shell 201, and the fan motor 208 is used to provide rotational kinetic energy for the fan blades 212. The power output end of the fan motor 208 is rotatably connected to a first pulley 209, and the outer surface of the fan shaft 207 is rotatably connected to a second pulley 210. The outer surfaces of the first pulley 209 and the second pulley 210 are rotatably connected to a rubber ring 211, and the rubber ring 211 is used to drive the second pulley 210 to rotate simultaneously when the first pulley 209 rotates with the fan motor 208.

[0024] In this embodiment of the invention, the low-temperature resistant fan motor 208 adopts a low-temperature adaptable sealing structure, which can start stably in low-temperature environments without the risk of icing, jamming, or circuit failure. It can continuously provide stable rotational kinetic energy to the fan blades 212, solving the problems of difficult low-temperature starting and unstable power output of traditional fan motors 208. The first pulley 209 is connected to the power output end of the fan motor 208, and the second pulley 210 is connected to the fan shaft 207 to ensure that the power transmission is not offset. The rubber ring 211 is made of low-temperature resistant nitrile rubber, which has good elasticity and wear resistance. It can not only fit tightly against the outer surface of the two pulleys to achieve synchronous transmission, but also buffer the vibration during the transmission process, avoiding transmission failure caused by hardening and breakage of the rubber ring 211 at low temperatures. At the same time, the flexible transmission design of the rubber ring 211 can also reduce the coaxiality error between the fan motor 208 and the fan shaft 207, ensuring that the fan blades 212 rotate smoothly, thereby providing continuous and stable wind pressure support for rapid steam delivery.

[0025] according to Figures 2-4 As shown, a metal mesh 213 is provided at the output end of the inner surface of the heat insulation shell 201, and a flexible hose 214 is bolted to one side of the outer wall of the heat insulation shell 201.

[0026] In this embodiment of the invention, the metal mesh 213 is made of stainless steel, which can effectively filter out any tiny impurities that may remain in the steam, preventing them from entering the furnace with the steam and adhering to the furnace wall, affecting the preheating effect and subsequent boiler operation, while also not obstructing the smooth passage of high-temperature steam. The flexible hose 214 is made of silicone material with dual properties of high and low temperature resistance, which can withstand the high temperature of the steam and resist the corrosion of the external low-temperature environment, preventing steam leakage caused by the brittleness and aging of the hose 214 at low temperatures. The bolt connection between the hose 214 and the insulation shell 201 ensures the sealing and firmness of the connection, and facilitates disassembly, replacement and maintenance in the future. At the same time, the hose 214 has good flexibility and can flexibly adjust the conveying angle according to the position of the boiler furnace opening to adapt to the docking requirements of different furnace openings.

[0027] according to Figure 5 As shown, the solution supply assembly 300 includes a frame 301, and a storage tank 302 is provided between the inner walls of the frame 301. The storage tank 302 is used to store glycerol compound solution.

[0028] In this embodiment of the invention, the frame 301 is firstly welded from cold-rolled steel plate, which has strong structural rigidity and good stability, and can stabilize the liquid storage tank 302 on the platform 103 of the mobile lifting component 100, so as to avoid the liquid storage tank 302 shaking or tilting during the movement and lifting of the device, which would cause leakage; wherein the liquid storage tank 302 is made of stainless steel, which is corrosion resistant and does not have impurities falling off, ensuring the cleanliness of the compound liquid.

[0029] according to Figure 5 As shown, the output end of the liquid storage tank 302 is connected to a quick-connect ball valve 303 via a pipeline, and the output end of the quick-connect ball valve 303 is connected to a vortex flow meter 304 via a pipeline.

[0030] In this embodiment of the invention, the quick-install ball valve 303 adopts a three-piece structure with a stainless steel valve core, providing excellent sealing performance and enabling rapid on / off switching of the compound liquid, significantly improving maintenance convenience in low-temperature environments. The vortex flow meter 304 features a low-temperature resistant and explosion-proof design, suitable for the industrial environment of the boiler site. It can monitor the flow rate of the compound liquid in real time and accurately, ensuring precise matching between the amount of compound liquid delivered and the heating power of the steam generating component 200. This avoids insufficient vaporization and droplet residue due to excessive delivery of the compound liquid, or dry burning of the heating tank and insufficient steam output due to insufficient delivery, thereby ensuring the stability of steam generation and the reliability of the preheating effect.

[0031] according to Figure 6 As shown, the mixing and stirring assembly 400 includes a mixing box 401. Bearing seats 402 are provided on both sides of the outer wall of the mixing box 401. A stirring shaft 403 is rotatably connected between the inner surfaces of the two bearing seats 402. A stirring blade 404 is rotatably connected to the outer surface of the stirring shaft 403.

[0032] In this embodiment of the invention, the mixing tank 401 is made of stainless steel, which has excellent sealing performance and can prevent the evaporation of the compound liquid and the entry of external impurities, thus ensuring the cleanliness of the compound liquid. Two bearing seats 402 are symmetrically fixed on both sides of the outer wall of the mixing tank 401, and are equipped with low-temperature resistant bearings inside, which can provide stable support for the stirring shaft 403, ensuring that the stirring shaft 403 rotates smoothly and reducing noise and component wear caused by vibration. The spiral stirring blade 404 is rotatably connected to the stirring shaft 403. When rotating, it can form an upward and downward convection stirring airflow, which can fully mix the glycerol compound liquid, prevent uneven stirring and stratification of the compound liquid components, and ensure that the compound liquid entering the steam generation component 200 has a consistent composition, thereby improving the stability and quality of steam generation.

[0033] according to Figure 6As shown, a stirring motor 406 is bolted to one side of the outer wall of the mixing box 401. A reducer 405 is rotatably connected to the power output end of the stirring motor 406. The power output end of the reducer 405 is rotatably connected to the outer surface of the stirring shaft 403.

[0034] In this embodiment of the invention, the stirring motor 406 is a low-temperature resistant geared motor, and its bolt connection with the mixing box 401 ensures both the stability of the installation and ease of disassembly, maintenance, and replacement. The reducer 405 adopts a gear reduction structure, which can convert the high-speed rotational power of the stirring motor 406 into the low-speed, high-torque rotational power of the stirring shaft 403. This ensures that the spiral stirring blades 404 have sufficient stirring force to achieve thorough mixing of the compound liquid, while also preventing splashing and bubble generation of the compound liquid caused by excessive stirring speed.

[0035] according to Figure 7 As shown, the movable lifting assembly 100 includes a platform 101. A plurality of support rods 102 are rotatably connected to the top of the platform 101. The top of each of the support rods 102 is rotatably connected to a table 103 via a pivot. One end of each support rod 102 is rotatably connected to a roller 105 via a bearing. The roller 105 is used to reduce the friction of each support rod 102 when the table 103 is raised or lowered.

[0036] In this embodiment of the invention, the platform 101 is firstly welded from cold-rolled steel plate, resulting in a robust structure and strong load-bearing capacity, preventing platform deformation and shaking during operation. Simultaneously, the bottom of the platform 101 works in conjunction with the casters 106 and push rods 107 to achieve flexible movement and positioning of the device. Multiple scissor-type support rods 102 are cross-rotated and connected to form a stable scissor-lifting structure, enabling smooth lifting of the platform 103 and precise adjustment of its height according to the boiler inlet height requirements, adapting to the docking needs of boiler inlets of different sizes and heights. The rollers 105 convert the sliding friction between the support rods 102 and the platform 103 into rolling friction during lifting, significantly reducing frictional resistance and preventing sluggish lifting caused by component jamming in low-temperature environments.

[0037] according to Figure 7 As shown, a cylinder 104 is rotatably connected to the top of the platform 101. The power output end of the cylinder 104 is rotatably connected to the outer surface of a rotating shaft, and the cylinder 104 is used to push the support rod 102, which is rotatably connected to the rotating shaft, to raise and lower the platform 103.

[0038] In this embodiment of the invention, cylinder 104 uses low-temperature adaptable hydraulic oil, which can stably extend and retract in low-temperature environments. Its rotational connection with platform 101 can adapt to the angle changes when support rod 102 is raised and lowered, avoiding damage caused by uneven force on the cylinder. As the power source for the lifting and lowering of platform 103, cylinder 104 can precisely control the lifting and lowering height of platform 103 by adjusting the extension and retraction of cylinder, perfectly adapting to the docking requirements of boiler furnace openings of different heights. The precise docking of the power output end of cylinder 104 with the rotating shaft of support rod 102 ensures that the cylinder can effectively drive the scissor-type support rod 102 to rotate crosswise when it extends and retracts, thereby driving platform 103 to rise and fall smoothly, improving the operational safety and reliability of the device, and adapting to the needs of rapid docking and precise preheating of boilers on site.

[0039] according to Figure 7 As shown, four casters 106 are bolted to the bottom of the outer wall of platform 101, and a push rod 107 is fixedly connected to the top of the outer wall of platform 101.

[0040] In this embodiment of the invention, four casters 106 are evenly distributed at the four corners of the bottom of the platform 101. They are made of high-strength, low-temperature resistant rubber with stainless steel cores, providing strong load-bearing capacity and allowing for flexible rolling in low-temperature environments. This ensures stable positioning when the device is connected to the boiler furnace opening, preventing connection deviations caused by device slippage. The push rod 107 is made of stainless steel with an anti-slip surface and is fixedly connected to the top of the platform 101. Its height is adapted to the operator's needs, facilitating the operator to move and adjust the position of the device. The push rod 107 and the casters 106 work together to achieve rapid movement and precise positioning of the device, significantly improving the ease of operation at the boiler site and adapting to the rapid preheating needs of multiple boilers and various scenarios.

[0041] During operation, before boiler preheating, the steam generating assembly 200 initiates its workflow. First, the fan motor 208 on one side of the outer surface of the insulation shell 201 starts, its power output driving the fixedly connected first pulley 209 to rotate. Through the transmission via the rubber ring 211 sleeved on the outer surface of the first pulley 209 and the second pulley 210, the fan shaft 207 rotates synchronously, thereby driving the fan blades 212 fixedly connected to the outer surface of the fan shaft 207 to rotate inside the fan shell 206, generating stable air pressure in advance to prepare for steam delivery. At this time, the inner surface of the insulation layer 202... A heating ring 203, fixedly connected at one end, is connected to an external power source to rapidly generate high-temperature heat. Multiple heat-conducting rods 204, thermally connected to one side of the outer wall of the heating ring 203, evenly conduct the heat to the entire cavity of the insulation layer 202. Simultaneously, the insulation shell 201, filled with aluminum foil foam insulation material, works synergistically with the insulation layer 202 to reduce heat loss from the cavity, ensuring the temperature inside the cavity rises rapidly to the required vaporization temperature. Once the preset vaporization temperature is reached, a glycerol compound solution, uniformly mixed by the mixing and stirring assembly 400, enters the cavity of the insulation layer 202. The heat is then transferred between the heating ring 203 and the heat-conducting rods 204. Under the continuous homogenization of heat generated by rod 204, the steam rapidly vaporizes to form high-temperature steam. Under the wind pressure generated by fan blade 212, the high-temperature steam moves towards the microporous membrane partition 205 located at the other end of the inner surface of the insulation layer 202. The microporous membrane partition 205, composed of a hydrophobic and breathable PTFE membrane, allows pure steam to pass through smoothly through a physical mechanism of adaptive permeability due to steam pressure difference and blocking by liquid surface tension, while effectively blocking incompletely vaporized liquid droplets, thus avoiding the risk of damage to the furnace wall under thermal stress. The pure steam passing through the microporous membrane partition 205 continues to flow forward and penetrates the inner surface of the insulation shell 201. The metal mesh 213 installed at the output end further filters out any tiny impurities that may remain in the steam, ensuring the cleanliness of the steam. The filtered high-temperature clean steam is then rapidly transported towards the boiler furnace opening through a low-temperature resistant silicone hose 214 bolted to one side of the outer wall of the insulation shell 201. The low-temperature resistant silicone hose 214, with its good flexibility and adaptability to high and low temperatures, can flexibly adjust the conveying angle according to the position of the boiler furnace opening, while avoiding steam leakage caused by brittleness and aging at low temperatures. This ensures that the high-temperature steam enters the boiler furnace in a full and stable manner, achieving rapid and uniform preheating of the furnace.Throughout the process, the steam generating assembly 200 ensures steam quality through the heat equalization structure of the heating ring 203 and the heat conducting rod 204, ensures preheating safety through the vapor-liquid separation structure of the microporous membrane diaphragm 205, improves preheating efficiency through the forced steam delivery structure of the fan assembly, and reduces heat loss in low-temperature environments through the insulation structure of the insulation shell 201 and the insulation layer 202. All components work systematically and collaboratively, without relying on complex algorithms or frequent manual intervention, to achieve stable generation and precise delivery of high-temperature clean steam, perfectly adapting to the operating conditions of rapid boiler start-up in extremely cold regions. At the same time, the residue after the condensation of the glycerol compound liquid steam undergoes a combustion reaction when the boiler burner is ignited, leaving no residue, significantly improving boiler start-up efficiency and operational safety. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
