Description

Technical Field

[0001] This invention relates to the field of circulating fluidized bed technology, specifically to a smart heating and energy-saving control device for heating stations. Background Technology

[0002] Circulating fluidized bed combustion (CFB) is a combustion technology based on the principle of fluidization. The fuel and ash mixture forms a fluidized combustion state in the lower part of the furnace. Unburned solid particles can be recovered through separation devices such as cyclone separators and returned to the furnace for further combustion. This equipment uses a suspended fluidized combustion method, ensuring complete combustion and offering significant advantages in improving combustion efficiency and synergistic control of pollutants within the furnace. It is widely used in centralized heating systems in heating stations.

[0003] However, during the actual operation of the heating station, the quality of the fuel entering the furnace is easily affected by external environmental factors such as rain, snow, and open-air storage. The fuel often has two problems: excessive moisture and excessive particle size, which have multiple negative impacts on the circulating fluidized bed heating system.

[0004] On the one hand, if the moisture content of the fuel entering the furnace is too high, the internal moisture will evaporate during combustion, producing a large amount of water vapor. This water vapor will continuously absorb heat from the furnace combustion, resulting in a decrease in effective heat production and a drop in bed temperature. At the same time, the water vapor will increase the total volume of flue gas, increasing exhaust heat loss and reducing the output heat energy of the equipment. To ensure the heating load, fuel consumption must be increased. A low bed temperature will also deviate from the optimal desulfurization reaction range of limestone, exacerbating incomplete combustion of fuel and increasing the concentration of pollutants such as dust, carbon monoxide, and sulfur dioxide in the flue gas. This significantly increases the operating load and maintenance costs of the downstream tail gas treatment equipment.

[0005] On the other hand, if the volume and size of the fuel particles entering the furnace exceed the standard, the large fuel particles, due to their greater weight, cannot be stably supported by the fluidizing air to form a suspended fluidized state. They are prone to sinking and accumulating at the bottom of the furnace, forming a fluidization dead zone. To ensure the basic fluidization effect, the operating power of the blower needs to be increased, resulting in a large waste of plant power. At the same time, only the surface of the large fuel particles can participate in combustion, and the interior is difficult to burn through. The carbon content of the bottom ash increases significantly, the furnace temperature rises slowly, and the overall thermal efficiency of the boiler decreases significantly. Long-term accumulation of large materials can also erode and wear down the wear-resistant castable in the furnace, and even block the air distribution device, increasing the probability of equipment failure and boiler shutdown for maintenance. Summary of the Invention

[0006] The purpose of this invention is to provide a smart heating and energy-saving control device for heating stations, so as to at least solve the problems of existing technologies that cannot prioritize the dehumidification of fuel and complete the crushing of fuel with excessive volume.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a smart heating and energy-saving control device for a heating station, comprising a frame, a combustion chamber, a jacket, and a cyclone separator. The combustion chamber is fixedly connected to the inner side of the frame, and the jacket is installed in the middle of the outer wall of the combustion chamber. The combustion chamber burns fuel, and the heat generated heats the circulating water flowing through the jacket, achieving heat exchange. The cyclone separator is installed on the top of the right side wall of the combustion chamber, and the bottom end of the cyclone separator is connected to the feed position of the combustion chamber. The cyclone separator separates fuel particles from flue gas, allowing the fuel particles to return to the combustion chamber for re-combustion. A dehumidification mechanism and two feeding mechanisms are respectively installed at the upper and lower ends of the left side wall of the combustion chamber. The dehumidification mechanism uses water vapor to heat the fuel, causing the moisture in the fuel to evaporate and dehumidify. The two feeding mechanisms add fuel and limestone to the combustion chamber respectively. The dehumidification mechanism includes a traction assembly installed on the top of the left side wall of the combustion chamber. A drive assembly is installed on the right end of the traction assembly to drive the traction assembly. A support plate is installed horizontally on the outer wall of the drive assembly. A wok is installed on the left end of the support plate for storing fuel. A coil is installed on the outer wall of the wok. The coil is connected to a water tank through a water pipe, allowing steam to pass through the coil and heat the wok. A pulverizing assembly is installed on the left end of the traction assembly. The pulverizing assembly is pulled by the traction assembly to pulverize fuel with a diameter exceeding the combustion range.

[0008] Preferably, the traction assembly includes a base mounted on the top of the left side wall of the combustion chamber, two hydraulic cylinders mounted on the lower surface of the base, a transmission box mounted on the output end of the hydraulic cylinders, a rotating unit mounted on the top of the transmission box via a bearing, and a swinging unit mounted inside the transmission box via a bearing, the rotating unit driving the swinging unit to swing.

[0009] Preferably, the rotating unit includes a first rotating shaft mounted on the right side of the upper surface of the transmission box via a bearing. A first turntable and a second turntable are respectively mounted on the upper and lower ends of the first rotating shaft. A plurality of protrusions are mounted on the upper surface of the first turntable along the circumferential direction, and a guide groove is provided on the side wall of the second turntable.

[0010] Preferably, the guide grooves are distributed in a wave-like pattern on the side wall of the second turntable.

[0011] Preferably, the swing unit includes a second rotating shaft mounted on the left side wall of the transmission box via a bearing. A first connecting rod and a second connecting rod are respectively mounted on the left and right ends of the second rotating shaft. The first connecting rod and the second connecting rod rotate synchronously through the connection of the second rotating shaft. A third connecting rod is mounted on the end of the first connecting rod away from the second rotating shaft via a pin. A plug rod that inserts into the inner cavity of the guide groove is mounted on the end of the second connecting rod away from the second rotating shaft.

[0012] It provides circulating kinetic energy for fuel pulverization, replacing the traditional forward and reverse rotation of motors and extending motor lifespan.

[0013] Preferably, the drive assembly includes a bracket mounted on the right end of the upper surface of the base, the bracket being fixedly connected to a support plate, a motor mounted on the right side of the upper surface of the bracket, a third rotating shaft locked to the output end of the motor via a coupling, a drive gear and a third turntable respectively mounted on the upper and lower ends of the third rotating shaft, a plurality of grooves matching the protrusions being formed along the circumference of the lower surface of the third turntable, a fourth rotating shaft mounted on the left end of the upper surface of the bracket via a bearing, a driven gear and a stirring blade respectively mounted on the upper and lower ends of the fourth rotating shaft, the driven gear meshing with the drive gear to rotate the stirring blade and stir the fuel in the wok.

[0014] It provides dual power for fuel drying and fuel pulverization, and the single power source facilitates subsequent maintenance, while the power is synchronized.

[0015] Preferably, both the inner cavity of the groove and the outer wall of the protrusion are triangular.

[0016] Preferably, the pulverizing assembly includes a pulverizing box and a valve body. The pulverizing box is installed at the left end of the transmission box. The valve body is installed at the center of the lower surface of the wok. A fifth rotating shaft is installed on the outer wall of the valve body via a bearing. A valve core and a drive gear are respectively installed at the left and right ends of the fifth rotating shaft. When the valve core rotates, it controls the opening and closing of the valve body. A sleeve is slidably connected to the outer wall of the valve body. A rack that meshes with the drive gear is installed on the upper surface of the pulverizing box. A first clamping plate is installed on the rear side of the inner cavity of the pulverizing box. A second clamping plate is installed on the front side of the inner cavity of the pulverizing box via a pin. The rear side wall of the second clamping plate is connected to the end of the third connecting rod via a pin. When the first connecting rod pulls one end of the third connecting rod to rotate back and forth centrifugally, the other end of the third connecting rod pulls the second clamping plate to swing back and forth.

[0017] The system controls material feeding and fuel crushing, resulting in a high degree of automation and reducing the labor intensity of workers.

[0018] Preferably, the distance between the first clamping plate and the second clamping plate gradually decreases from top to bottom.

[0019] The present invention proposes a smart heating energy-saving control device for heating stations, the advantages of which are as follows: 1. This invention utilizes a motor to drive the third rotating shaft, which, through the meshing of the drive and driven gears, drives the stirring blades to continuously stir the fuel inside the wok. Waste heat steam from the system is introduced into the coil to continuously heat the wok, achieving uniform heating and dehumidification of the fuel. After pretreatment, the fuel moisture content is reduced, which can prevent the evaporation of moisture in the fuel from absorbing a large amount of heat from the furnace, effectively reducing system heat loss. At the same time, it reduces the total amount of flue gas generated and reduces exhaust heat loss. Stable furnace conditions can reduce the production of flue gas pollutants, reduce the operating load of tail gas treatment equipment, and reduce fuel consumption, thus having good energy-saving and environmental protection benefits.

[0020] 2. During the upward movement of the transmission box in this invention, the rack moves upward and meshes with the drive gear, driving the valve core to rotate and open the valve body. The dried fuel falls automatically. At the same time, the groove of the third turntable and the protrusion of the first turntable interlock, transmitting the motor power to the first rotating shaft, which drives the wave-shaped guide groove of the second turntable to rotate synchronously. The guide groove and the insert rod cooperate to drive the second connecting rod and the second rotating shaft to swing back and forth. The third connecting rod pulls the second clamping plate to swing back and forth, repeatedly squeezing and crushing large pieces of fuel that exceed the volume limit. This mechanism integrates the dual functions of feeding control and particle crushing. The crushed fuel particles meet the particle size requirements for fluidized combustion and can be stably suspended in the furnace. There is no need to increase the fan power to compensate for the fluidization effect, reducing plant power consumption. At the same time, it solves the problems of incomplete combustion of large pieces of fuel and slow furnace heating, reduces the carbon content of the bottom ash, and improves the overall thermal efficiency of the boiler.

[0021] 3. The dehumidification and crushing mechanisms are integrated and arranged in an integrated manner, completing the drying and crushing pretreatment process before the fuel enters the combustion chamber. This solves a series of operational defects caused by high humidity and large particle fuel, such as fluidization deterioration, increased energy consumption, low combustion efficiency, and fluctuations in environmental protection indicators, thereby comprehensively improving the operational stability and economic performance of the circulating fluidized bed heating station heating system.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-9 This invention provides a technical solution: a smart heating and energy-saving control device for a heating station, comprising a frame 1, a combustion chamber 2, a jacket 4, and a cyclone separator 4. The combustion chamber 2 is fixedly connected to the inner side of the frame 1, and the jacket 3 is installed in the middle of the outer wall of the combustion chamber 2. The combustion chamber 2 burns fuel, and the heat generated heats the circulating water flowing through the jacket 4 to achieve heat exchange. The cyclone separator 4 is installed on the top of the right side wall of the combustion chamber 2, and the bottom end of the cyclone separator 4 is connected to the feed position of the combustion chamber 2. The cyclone separator 4 separates fuel particles from flue gas, allowing the fuel particles to return to the combustion chamber 2 for re-combustion. The upper and lower ends of the left side wall of the combustion chamber 2 are respectively equipped with a dehumidification mechanism 5 and two feeding mechanisms 6. The dehumidification mechanism 5 uses water vapor to heat the fuel, causing the water in the fuel to evaporate and dehumidify. The two feeding mechanisms 6 respectively add fuel and limestone to the combustion chamber 2. The dehumidification mechanism 5 includes a traction assembly 51 installed on the top of the left side wall of the combustion chamber 2. A drive assembly 52 is installed on the right end of the traction assembly 51. The drive assembly 52 is used to drive the traction assembly 51. A support plate 53 is installed horizontally on the outer wall of the drive assembly 52. ​​A wok 54 is installed on the left end of the support plate 53. The wok 54 is used for fuel storage. The inner wall of the wok 54 is curved, allowing the fuel to roll freely and be heated evenly. A coil 55 is installed on the outer wall of the wok 54. The coil 55 is connected to the water tank through a water pipe, allowing water vapor to pass through the coil 55 to heat the wok 54, avoiding the waste of water vapor heat and saving fuel drying energy consumption. A pulverizing assembly 56 is installed on the left end of the traction assembly 51. The pulverizing assembly 56 is pulled by the traction assembly 51 to pulverize fuel with a diameter exceeding the combustion range.

[0026] As a preferred embodiment, the traction assembly 51 further includes a base 511 mounted on the top of the left side wall of the combustion chamber 2. Two hydraulic cylinders 512 are mounted on the lower surface of the base 511. A transmission box 513 is mounted on the output end of the hydraulic cylinders 512. The transmission box 513 is driven to rise and fall by the hydraulic cylinders 512. A rotating unit 514 is mounted on the top of the transmission box 513 via a bearing. A swinging unit 515 is mounted on the inner cavity of the transmission box 513 via a bearing. The swinging unit 515 is driven to swing by the rotating unit 514.

[0027] As a preferred embodiment, the rotating unit 514 further includes a first rotating shaft 5141 mounted on the right side of the upper surface of the transmission box 513 via bearings. A first rotating disk 5142 and a second rotating disk 5143 are respectively mounted on the upper and lower ends of the first rotating shaft 5141. Several protrusions 5144 are mounted circumferentially on the upper surface of the first rotating disk 5142. A guide groove 5145 is provided on the side wall of the second rotating disk 5143. The guide groove 5145 is distributed in a wave-like manner on the side wall of the second rotating disk 5143. As the guide groove 5145 rotates with the second rotating disk 5143, the symmetrical concave and convex curved surfaces of the guide groove 5145 will alternately press the insertion rod 5155 upward and downward. Relying on the continuous alternating pushing action of the curved surfaces, the second rotating shaft 5151 is driven to achieve reciprocating alternating forward and reverse rotation.

[0028] The first rotating shaft 5141, which rotates continuously in one direction, drives the second rotating disk 5143 to rotate. The guide groove 5145, together with the insertion rod 5155, can output reciprocating oscillating power. There is no need for the drive motor to frequently start and stop in both directions, which effectively reduces the impact load on the motor and extends the service life of the motor and transmission components. The wavy guide groove 5145 has a smooth curved transition, and the insertion rod 5155 slides in the guide groove 5145 without jamming. It can stably and continuously drive the oscillating unit 515 to operate, ensuring that the reciprocating crushing action of the crushing component 56 on the excessive fuel particles is continuous and reliable.

[0029] As a preferred embodiment, the swing unit 515 further includes a second rotating shaft 5151 mounted on the left side wall of the transmission box 513 via bearings. A first connecting rod 5152 and a second connecting rod 5153 are respectively mounted on the left and right ends of the second rotating shaft 5151. The second rotating shaft 5151 connects the first connecting rod 5152 and the second connecting rod 5153, causing them to rotate synchronously. A third connecting rod 5154 is mounted on the end of the first connecting rod 5152 away from the second rotating shaft 5151 via a pin. When the first link 5152 pulls one end of the third link 5154 to swing back and forth, the other end of the third link 5154 can pull the second clamping plate 569 to move back and forth, clamping and crushing the excessive fuel particles. The end of the second link 5153 away from the second rotating shaft 5151 is equipped with an insert rod 5155 that is inserted into the inner cavity of the guide groove 5145. The outer wall of the insert rod 5155 is cylindrical, and the curved surface of the insert rod 5155 slides more smoothly in the guide groove 5145, avoiding jamming.

[0030] The swing unit 515 uses the second rotating shaft 5151 to achieve synchronous linkage between the first connecting rod 5152 and the second connecting rod 5153. The cylindrical insert rod 5155 and the guide groove 5145 slide smoothly without obstruction, which can stably convert the reciprocating thrust output by the rotating unit 514 into the reciprocating squeezing action of the second clamping plate 569, continuously crushing the excessive fuel particles. The entire linkage mechanical transmission structure has smooth transmission and low failure rate, and can provide a continuous and uniform crushing clamping force for the crushing component 56, ensuring stable crushing effect of large fuel particles.

[0031] As a preferred embodiment, the drive assembly 52 further includes a bracket 521 mounted on the right end of the upper surface of the base 511. The bracket 521 is fixedly connected to the support plate 53. A motor 522 is mounted on the right side of the upper surface of the bracket 521. A third rotating shaft 523 is locked to the output end of the motor 522 via a coupling. A drive gear 524 and a third rotating disk 525 are respectively mounted on the upper and lower ends of the third rotating shaft 523. A plurality of grooves 526 matching the protrusions 5144 are formed on the lower surface of the third rotating disk 525 in the circumferential direction. Both the cavity and the outer wall of the protrusion 5144 are triangular. When the protrusion 5144 and the inclined surface of the groove 526 are pressed against each other, the protrusion 5144 and the groove 526 can be automatically aligned, which facilitates the connection between the third rotating shaft 523 and the first rotating shaft 5141. The left end of the upper surface of the bracket 521 is equipped with a fourth rotating shaft 527 through a bearing. The upper and lower ends of the fourth rotating shaft 527 are respectively equipped with a driven gear 528 and a stirring blade 529. The driven gear 528 is meshed with the driving gear 524, which makes the stirring blade 529 rotate and stir-fry the fuel in the wok 54.

[0032] The stirring blades 529 are synchronously driven by gear meshing to complete the fuel stirring and dehumidification. The power is transmitted through the triangular concave-convex structure of the third turntable 525 and the first turntable 5142, and the power is supplied to the crushing mechanism at the same time. The entire power system has a high degree of integration and few parts, which facilitates unified inspection and maintenance. The triangular matching protrusions 5144 and grooves 526 have an automatic centering and calibration function, which makes it less likely to jam when lifting and docking. The power transmission is stable and reliable, and can simultaneously ensure the continuous operation of the two pre-treatment processes of fuel drying and large piece crushing, which greatly improves the automated collaborative operation capability of the equipment.

[0033] As a preferred embodiment, the pulverizing assembly 56 further includes a pulverizing chamber 561 and a valve body 562. The pulverizing chamber 561 is installed at the left end of the transmission box 513. The valve body 562 is installed at the center of the lower surface of the wok 54. A fifth rotating shaft 563 is mounted on the outer wall of the valve body 562 via bearings. A valve core 564 and a drive gear 565 are respectively installed at the left and right ends of the fifth rotating shaft 563. When the valve core 564 rotates, it controls the opening and closing of the valve body 562. A sleeve 566 is slidably connected to the outer wall of the valve body 562. A rack 567 is installed on the upper surface of the pulverizing chamber 561 and meshes with the drive gear 565. When the rack 567 moves up and down with the pulverizing chamber 561, it can cause the drive gear 565 to drive the valve core 564. 4. Rotate back and forth to open and close the valve body 562, allowing the feeding and crushing to proceed simultaneously. A first clamping plate 568 is installed on the rear side of the inner cavity of the crushing box 561, and a second clamping plate 569 is installed on the front side of the inner cavity of the crushing box 561 via a pin. The rear side wall of the second clamping plate 569 is connected to the end of the third connecting rod 5154 via a pin. When the first connecting rod 5152 pulls one end of the third connecting rod 5154 to rotate back and forth centrifugally, the other end of the third connecting rod 5154 pulls the second clamping plate 569 to swing back and forth. The distance between the first clamping plate 568 and the second clamping plate 569 gradually decreases from top to bottom, crushing the fuel step by step. Anti-slip ridges are provided on the opposite surfaces of the first clamping plate 568 and the second clamping plate 569 to prevent slippage when crushing fuel.

[0034] The automatic opening and closing of the valve body 562 for feeding is achieved by the lifting linkage rack 567 of the transmission box 513, the drive gear 565 and the valve core 564. At the same time, the second clamping plate 569 is driven to reciprocate and crush the fuel by the linkage mechanism of the swing unit 515, thus integrating the feeding control and fuel crushing functions into one synchronous operation, without the need for two independent control systems to control them separately.

[0035] The first clamping plate 568 and the second clamping plate 569 are matched with a gap that is wider at the top and narrower at the bottom. The anti-slip ridge can prevent large pieces of fuel from being squeezed and slipping, so as to achieve uniform crushing of fuel in stages and stably produce standard particle size fuel that is suitable for circulating fluidized bed combustion. This eliminates problems such as dead fluidized bed in the furnace, increased power consumption of blowers, incomplete combustion and reduced thermal efficiency caused by large pieces of fuel entering the furnace. There is no need for manual intervention in the screening and crushing process, which effectively reduces the manual operation load on site.

[0036] As a preferred embodiment, the feeding mechanism 6 further includes a hopper 61, with a solenoid valve 62 installed at the bottom opening of the hopper 61. The solenoid valve 62 is a proportional solenoid valve, which can control the amount of material fed and save fuel consumption. A conveyor box 63 is installed horizontally at the bottom of the solenoid valve 62. A conveyor belt 64 is installed inside the conveyor box 63, and the fuel is conveyed from left to right through the conveyor belt 64. A guide chute 65 fixed to the outer wall of the combustion chamber 2 is installed at the right end of the conveyor box 63, and the fuel is guided to the designated position in the combustion chamber 2 through the guide chute 65.

[0037] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0038] Step 1: Solenoid valve 62 controls the discharge rate, allowing fuel and limestone to fall onto conveyor belt 64. The conveyor belt 64 transports the fuel and limestone to the right, and the guide chute 65 guides the fuel and limestone into combustion chamber 2. The upward airflow in combustion chamber 2 disperses the fuel and limestone. The fuel burns in combustion chamber 2, and the limestone desulfurizes the sulfides produced during combustion. The circulating heat in jacket 3 is heated, thus achieving heating. Cyclone separator 4 uses centrifugal force to separate unburned fuel solids from flue gas, and the fuel returns to combustion chamber 2 for re-combustion, saving heating costs. Step 2: Water vapor is generated during the circulating heat rise. The water vapor is introduced into the coil 55 and the heat of the water vapor is used to heat the wok 54, thereby heating the fuel in the wok 54. Step 3: The motor 522 drives the drive gear 524 and the third turntable 525 on the third rotating shaft 523 to rotate. Under the transmission condition of the drive gear 524 and the driven gear 528, the stirring blade 529 rotates. The stirring blade 529 stirs the fuel, so that the fuel is heated evenly and dehumidifies the fuel. This avoids the problems of water vapor absorbing heat during combustion, incomplete combustion of fuel, and increased flue gas volume. Step four, during material feeding, the transmission box 513 is driven to rise by the hydraulic cylinder 512, and the first turntable 5142 and the second turntable 5143 on the first rotating shaft 5141 rise. When the protrusion 5144 enters the groove 526, the first rotating shaft 5141 and the third rotating shaft 523 rotate coaxially. At the same time, when the rack 567 rises, it moves the drive gear 565, causing the valve core 564 to rotate and open the valve body 562. Step 5: Fuel in the wok 54 passes through the valve body 562 and falls between the first clamping plate 568 and the second clamping plate 569. Fuel particles that meet the fuel standard fall into the hopper 61 through the gap between the first clamping plate 568 and the second clamping plate 569, while excessively large fuel particles get stuck in the gap. When the third rotating shaft 523 rotates coaxially with the first rotating shaft 5141, the second rotating disk 5143 also rotates. The curved surface of the guide groove 5145 repeatedly presses the insert rod 5155 up and down, causing the second connecting rod 5153 to drive the second rotating shaft 5151 to rotate back and forth. At the same time, the first connecting rod 5152 on the second rotating shaft 5151 drives one end of the third connecting rod 5154 to swing back and forth. The third connecting rod 5154 pulls the second clamping plate 569 to swing back and forth, squeezing and crushing the fuel to prevent the fuel from being too large and affecting combustion, or falling down and clogging the air distributor at the bottom of the combustion chamber 2.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
