Description

Technical Field

[0001] This invention relates to the field of ash removal technology, specifically to a movable suspended ash remover for boilers and an ash removal method. Background Technology

[0002] Boiler ash accumulation is a common problem in energy conversion systems such as thermal power generation and waste incineration, especially in the waste incineration field. With the acceleration of global urbanization, the amount of municipal solid waste collected has exceeded 200 million tons, of which about 65% is treated by incineration. However, the composition of waste is complex (containing plastics, metals, organic matter, etc.), and the operating conditions of incineration fluctuate greatly. Ash, molten salts, and heavy metal compounds produced after incineration easily deposit on the boiler's heating surfaces. Boiler ash accumulation not only increases boiler flue gas temperature, reduces boiler efficiency, and decreases power generation, but also causes excessively high superheater inlet flue gas temperature, accelerating the high-temperature corrosion process, leading to energy efficiency losses and equipment safety risks. Currently used boiler soot blowing technologies still have many shortcomings, such as: 1) both steam and shock wave soot blowing are high-pressure, and high soot blowing frequency increases the probability of tube rupture; 2) there are dead zones on the boiler heating surfaces, resulting in incomplete ash removal; 3) it consumes steam or acetylene, increasing operating costs; 4) hydraulic soot blowing technology is more commonly used in vertical flue cleaning of coal-fired units. Hydraulic soot removers for coal-fired boilers are located on the outside of the flue. High-pressure water jets spray water into the furnace, and the trajectory of the water flow on the furnace wall is controlled by adjusting the angle of the jets to maximize coverage and achieve cleaning. However, because coal-fired power plant flues are square while waste-to-energy boiler flues are long and narrow rectangles, this technology creates blind spots in boiler cleaning. Therefore, hydraulic soot removal equipment for coal-fired power plants is not suitable for waste incineration boilers.

[0003] Chinese utility model patent CN 221505044 U discloses a hydraulic ash removal device for a waste-to-energy plant, including a top plate, a middle plate, and a cleaning component. The cleaning component can move up and down for feeding. A lead screw is rotatably mounted under the top plate, and a first motor is mounted on the top plate. The output shaft of the first motor is rotatably connected to the lead screw. The cleaning component includes a connecting plate, a connecting shaft, and a turntable. The connecting shaft is fixed on the turntable, and the turntable is rotatably connected to the connecting plate. Several hinged parts are provided circumferentially on the outer side of the turntable, and spray rods are hinged in the hinged parts. The angle of the spray rods can be adjusted by rotation. The up and down movement of the cleaning component in this device is driven by a lead screw, which has a limited transmission distance. The depth of the second and third flues of a boiler can generally reach more than 15 meters, and the lead screw transmission cannot reach this distance, meaning that it cannot achieve full-area ash removal for the second and third flues. The cleaning component includes a second motor and electric push rods, etc. During the ash removal process, it needs to enter the high-temperature flue. In the high-temperature flue gas environment of the second flue, which is close to 1000°C, the motor and other electric components are easily damaged and cannot work properly.

[0004] Chinese invention patent application CN 113551248 A discloses an online hydraulic ash removal system for a waste incineration waste heat boiler. The system includes a cleaning component and several prefabricated pipes. A first driving component is connected to the cleaning component to drive its lateral movement, and the movement path of the cleaning component passes above each prefabricated pipe. The lower ends of all prefabricated pipes are connected to the boiler flue. The cleaning component includes cleaning nozzles and a second driving component, which drives the cleaning nozzles to move up and down within the prefabricated pipes to clean the accumulated ash and coke in the flue. This system lacks a detailed transmission mechanism; the cleaning nozzles can only move up and down without rotation. If an annular nozzle is used, there is no selectivity, and the water flow is the same regardless of distance from the water-cooled wall, resulting in poor ash removal. If a conical or fan-shaped nozzle is used, it can only cover a partial area, further hindering the ash removal effect.

[0005] Chinese utility model patent CN 221237870 U discloses a waste heat boiler with hydraulic ash removal function. The hydraulic ash removal device includes a pressure pump, a metal hose, and a guiding device. The guiding device is installed on the top of the boiler body. The pressure pump is connected to one end of the metal hose. The other end of the metal hose passes around the guiding device and extends vertically into the boiler body under the guidance of the guiding device. A nozzle is connected to the end of the metal hose that extends into the boiler body. The hydraulic ash removal device sprays and cleans the heating surfaces inside the boiler body to reduce ash accumulation. This patent sets two hydraulic ash removal devices on the top of the boiler, one each in the second and third flues, indicating that the hydraulic ash removal device is fixed and cannot be moved, resulting in higher costs. Similarly, the ash removal nozzle can only move up and down, without rotational movement, which cannot achieve a good ash removal effect.

[0006] Chinese invention patent publication number CN 113503555 B discloses a three-degree-of-freedom hydraulic soot cleaner and a soot cleaning method. Chinese invention patent application publication number CN 118009334 A discloses a multi-nozzle hydraulic soot cleaner. Both CN113503555 B and CN 118009334 A are side-wall entry hydraulic soot cleaners. Side-wall entry hydraulic soot cleaners have a limited soot cleaning range, and multiple devices need to be arranged in a single flue to achieve full coverage, which is very costly.

[0007] The top-suspended hydraulic soot removal system allows for the horizontal movement of the soot remover, enabling one soot remover device to be installed per boiler. This system has a simple structure and low investment cost. Summary of the Invention

[0008] Technical Problem Solved: Addressing the problems existing in the prior art, this invention proposes a movable suspended soot remover and cleaning method for boilers. A movable suspended hydraulic soot remover is installed at the top of the boiler. The soot remover moves freely horizontally on the boiler's top platform to clean the boiler's heating surfaces. The structure is simple and the investment cost is low. Employing single-nozzle and multi-nozzle modes, it utilizes the circular rotation of the cleaning module itself. Simultaneously, based on the required distance between the nozzle and the cleaning wall, the nozzle position and the backlash force of the water flow are adjusted to achieve comprehensive cleaning of the boiler without dead angles, achieving optimal cleaning results. Furthermore, a special structural design protects the easily damaged metal hose, extending its service life and reducing maintenance and operating costs.

[0009] Technical Solution: The first objective of this invention is to provide a movable suspended soot remover for boilers, comprising an outer frame and a soot removal module. The outer frame is movable above the boiler, and the soot removal module is rotatably located inside the outer frame. The soot removal module includes a water inlet pipeline system, a first rotating component, a second rotating component, a coil system, and a soot removal module frame. The water inlet pipeline system includes a water inlet end, a connecting pipe, a support pipe, a soot removal hose, and a nozzle, which are connected in sequence. The first rotating component and the second rotating component are respectively located at the top and bottom of the soot removal module frame for rotatably connecting to the outer frame. The coil system includes a coiling reel and a coiling reel drive connected thereto. The soot removal hose is evenly coiled on the coiling reel in a spiral manner. The nozzle is located at the wire release end of the coiling reel. The support pipe is located on the central axis of the coiling reel, and the two are fixedly connected. The two ends of the support pipe are supported on the soot removal module frame by bearing seats. The coiling reel drive drives the coiling reel to rotate around the central axis, thereby driving the nozzle to move up and down inside the boiler.

[0010] The nozzle can be a single nozzle or a multi-nozzle nozzle. When the nozzle is a single nozzle, it includes a single nozzle body, a single fan-shaped nozzle connected to it, a partition, an IMU (Inertial Measurement Unit), wires, and a fixing compound. The single nozzle body is connected to the cleaning hose connector. The partition is located on the upper part of the single nozzle body and forms a sealed space with the top cover of the single nozzle body and the cleaning hose connector. The IMU is horizontally located in the sealed space, and the remaining space is filled with fixing compound. One end of the wire is connected to the IMU, and the other end passes through the cleaning hose for wiring control and data transmission.

[0011] When the nozzle is a multi-nozzle nozzle, the nozzle includes a multi-nozzle nozzle body and at least two fan-shaped nozzles connected thereto, and the multi-nozzle nozzle body is connected to the dust removal hose connector.

[0012] Preferably, the outer frame includes an aluminum profile frame and a dust removal module support roller; the dust removal module frame includes an aluminum profile and connecting corner bracket frame and a bottom ring; the first rotating component is a transmission gear assembly, including a large gear, a small gear meshing with it, and a drive motor. The large gear is fixed on the outer frame, the small gear is connected to the drive motor, and the drive motor is connected to the dust removal module frame through a motor fixing component; the second rotating component is a dust removal module support roller located in the lower part of the outer frame and a bottom ring located at the bottom of the dust removal module frame. The bottom ring rotates in place on the dust removal module support roller; the drive motor drives the small gear to rotate circumferentially around the center of the large gear, thereby driving the dust removal module frame to rotate.

[0013] Preferably, the water inlet pipeline system further includes a water inlet pipe, a rotary joint, and a fixed clamp block connected in sequence. The water outlet end of the fixed clamp block is connected to the water inlet end of the connecting pipe, and the top of the fixed clamp block is connected to a thrust bearing located in the middle of the large gear, thereby realizing the rotational connection with the large gear. The lower part of the fixed clamp block is fastened to the dust removal module frame by bolts.

[0014] Preferably, the coil pulley drive includes a motor and matching small synchronous pulley A, synchronous belt A, and large synchronous pulley B. The large synchronous pulley A and large synchronous pulley B are fixed at both ends of the support pipe, and the three are relatively fixedly connected. The motor drives the small synchronous pulley A to rotate, which in turn drives the large synchronous pulley A to rotate through the synchronous belt A. The large synchronous pulley A drives the support pipe to rotate, thereby rotating the coil pulley. The nozzle drives the cleaning hose to move up and down, achieving the purpose of cleaning the entire flue.

[0015] Preferably, the coil system further includes a wire feeding screw drive system, which includes a large synchronous pulley B, a synchronous belt B, a small synchronous pulley B, a screw, and a pulley. While the coiling wheel rotates, the large synchronous pulley B drives the small synchronous pulley B to rotate via the synchronous belt B. The small synchronous pulley B and the screw are relatively fixed, and the small synchronous pulley B drives the screw to rotate. The screw and pulley are ball screw drive structures, so that while the screw rotates, the pulley moves evenly left and right. The wire feeding end of the cleaning hose on the coiling wheel is movably connected to the surface of the pulley.

[0016] Preferably, the movable suspended boiler soot remover also includes a control system, which includes a water supply valve, a water tank, an inlet valve, a filter, a water pump, a flow transmitter, a pressure transmitter, a check valve, and an electric regulating valve. Industrial water is connected to the inlet pipe of the water tank through the water supply valve, and the outlet of the water tank is connected to the inlet pipe of the movable suspended boiler soot remover in sequence through the inlet valve, filter, water pump, flow transmitter, pressure transmitter, check valve, and electric regulating valve.

[0017] Preferably, the control system further includes a cooling water inlet main valve, several cooling water inlet branch valves, a compressed air inlet main valve, a pneumatic triplet, compressed air inlet branch valves, a solenoid directional valve, a pneumatic gate valve, several boiler guide pipes, and a cooling water inlet. One end of the boiler guide pipe is connected to the ash removal port at the top of the boiler, and the other end is connected to the pneumatic gate valve. The cooling water inlet is located at the bottom of the boiler guide pipe. Compressed air passes sequentially through the compressed air inlet main valve, the pneumatic triplet, and the compressed air inlet branch valves. The system includes a circuit valve, a solenoid directional valve, and a pneumatic gate valve. The pneumatic gate valve is used to control its opening and closing. When ash removal is required, the pneumatic gate valve is opened, and the ash removal hose and nozzle enter the boiler from the boiler guide pipe for ash removal. When ash removal is not required, the pneumatic gate valve is closed. A branch line is branched off from the connecting pipeline between the water pump and the flow transmitter. This branch line then branches into several pipelines, each connecting to the cooling water inlet of each boiler guide pipe. The main cooling water inlet valve is located on the branch pipeline, and the cooling water inlet branch valves are located on the branch pipelines.

[0018] Preferably, the outer frame also includes support casters and handles, wherein the support casters are located at the bottom of the aluminum profile frame and the handles are located on one side of the aluminum profile frame; the movable suspended soot remover for the boiler also includes guide rails for use with the support casters, the guide rails are located on the top platform of the boiler and are used to limit the movement of the support casters.

[0019] Preferably, the outer frame also includes a water pipe fixing clamp, which is located at the top of the outer frame and is used to fix the water inlet pipe; the dust removal module frame also includes a guide tube, which is fixed to the bottom of the aluminum profile and connecting corner frame and the center of the bottom ring, providing track support for the up and down movement of the dust removal hose.

[0020] The second objective of this invention is to provide a method for cleaning a boiler with a movable suspended soot remover, as described above, comprising the following steps:

[0021] Step 1: When cleaning ash, place the movable suspended ash cleaner above the boiler, so that the nozzle is suspended above the flue to be cleaned.

[0022] Step 2: Activate the coil wheel drive to make the coil wheel rotate around the central axis, thereby displacing the unwinding end of the cleaning hose that is evenly coiled in a spiral pattern on the coil wheel, and thus moving the nozzle up and down inside the boiler; by rotating component one and rotating component two, the cleaning module frame is rotated, thereby driving the cleaning hose and nozzle to rotate.

[0023] Step 3: When the vertical travel of the flue to be cleaned does not exceed 5 meters, a multi-nozzle spray head is used, with each fan-shaped nozzle evenly distributed. The cleaning operation is achieved by adjusting the number of nozzles, their rotation speed, vertical movement position, and the water flow rate in the water inlet pipeline system. When the vertical travel of the flue to be cleaned exceeds 5 meters, in addition to adjusting the position of the nozzles by driving the nozzles up and down inside the boiler through the starter wheel drive and by rotating the nozzles through rotating component one and rotating component two, a single-nozzle spray head is used. The water flow impact force tilts the cleaning hose and the nozzles downwards. By controlling the water flow rate in the water inlet pipeline system, the tilt angle of the nozzles is controlled, thereby adjusting the spray distance. The inertial measurement unit (IMU) mounted on the nozzle accurately measures the tilt angle of the cleaning hose, allowing the cleaning to reach the lower part of the flue with a shorter descent distance, thus extending the service life of the hose.

[0024] Beneficial effects:

[0025] (1) The present invention adopts a single nozzle or multiple nozzle mode to replace the ring nozzle in the prior art. It can overcome the problems of not realizing the differentiated and targeted ash cleaning of boilers in the prior art. It utilizes the circumferential rotation of the ash cleaning module itself, and at the same time, according to the need for the distance between the nozzle and the cleaning wall, it uses the adjustment and control of the nozzle position and the backlash force of the water flow to achieve comprehensive ash cleaning of the boiler without dead angles and achieve the best ash cleaning effect.

[0026] (2) This invention employs multiple structures to protect the metal flexible hose:

[0027] First, when cleaning vertical flues, a single nozzle is used to reduce the downward extension height of the hose. The water flow impact reaction force causes the hose to tilt at a certain angle, increasing the water volume. This allows the lower wall of the flue to be cleaned even when the hose extends a short distance. This shortens the hose's operating distance, reduces cleaning time, extends its lifespan, and reduces costs.

[0028] Secondly, a cooling water circuit is connected to the boiler guide pipe. By forming a water film around the metal hose, the metal hose is cooled and protected, extending its lifespan. Simultaneously, during the upward movement of the metal hose after ash removal, this water flow cleans the hose, reducing the adhesion and deposition of corrosive substances such as alkali metal salts on its surface, thereby reducing corrosion and further extending its lifespan.

[0029] Finally, the hose contains metal cables, which provide tensile strength and toughness.

[0030] (3) The present invention provides a movable suspended hydraulic soot remover at the top of the boiler. The soot remover moves freely horizontally on the top platform of the boiler to remove soot from the boiler heating surface. The structure is simple and the investment cost is low.

[0045] The present invention will now be described in more detail with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the invention.

[0046] Example 1

[0047] This embodiment provides a movable suspended soot remover for boilers (suspended hydraulic soot removal device). See [link / reference]. Figure 1The system includes an outer frame 1, a soot cleaning module 2, a control system 3, and a guide rail 4. The outer frame 1 is movable and located above the boiler. The soot cleaning module 2 is rotatably located inside the outer frame 1. The control system 3 is used to control the water inlet pipeline and the compressed air pipeline. The guide rail 4 is used in conjunction with the support casters 103 in the outer frame 1 and is located on the top platform of the boiler to limit the movement of the support casters 103.

[0048] See Figure 2 The outer frame 1 includes an aluminum profile frame 101, ash-cleaning module support rollers 102, support casters 103, handles 104, and water pipe fixing clamps 105. The aluminum profile frame 101 is assembled from overlapping aluminum profiles, making assembly simple and resulting in lightweight and low-cost construction. The ash-cleaning module support rollers 102 are located in the lower middle part of the outer frame 1 to support the ash-cleaning module 2. The support casters 103 are located at the bottom of the aluminum profile frame 101 to support it. The handle 104 is located on one side of the aluminum profile frame 101 for easy operation of the boiler's movable suspended ash cleaner. The water pipe fixing clamps 105 are located at the top of the aluminum profile frame 101 to fix the water inlet pipe 211.

[0049] See Figure 3 and Figure 4 The ash removal module 2 includes a water inlet pipeline system 201, a transmission gear assembly 202, a coil system 203, and an ash removal module frame 204. The water inlet pipeline system 201 is used for water inlet, the transmission gear assembly 202 is used to realize the rotation of the ash removal module 2 inside the outer frame 1, and the coil system 203 is used to realize the up and down movement of the water inlet pipeline system 201 inside the boiler during ash removal.

[0050] The water inlet pipeline system 201 includes a water inlet pipe 211, a rotary joint 212, a fixed clamp 213, a connecting pipe 214, a support pipe 215, a cleaning hose 216 (made of metal), and a nozzle 217 connected in sequence. The rotary joint 212 is used to realize the relative rotation between the fixed clamp 213 and the water inlet pipe 211. The top of the fixed clamp 213 is connected to a thrust bearing located in the middle of the large gear 221, thereby realizing the rotational connection with the large gear 221. The lower part of the fixed clamp 213 is fastened to the cleaning module frame 204 by bolts.

[0051] The transmission gear assembly 202 includes a large gear 221, a meshing small gear 222, and a drive motor 223. The large gear 221 is fixedly mounted on the outer frame 1, and the small gear 222 is connected to the drive motor 223. The drive motor 223 is connected to the dust removal module frame 204 via a motor fixing component. The large gear 221 is connected in the middle to a fixing block 213 in the water inlet pipe system 201 via a thrust bearing. The fixing block 213 is fastened to the dust removal module frame 204 by bolts. The drive motor 223 drives the small gear 222 to rotate, which in turn drives the dust removal module frame 204 to rotate around the center of the large gear 221. This further drives the coil system 203 to rotate, thereby driving the dust removal hose 216 and the nozzle 217 to rotate, thus achieving the purpose of full-area dust removal.

[0052] The coil system 203 includes a coil reel 231, a coil reel drive 232 connected thereto, and a lead screw transmission system 233.

[0053] The fixed clamp 213 is connected to the support pipe 215 through the connecting pipe 214. The support pipe 215 is located on the central axis of the coiling reel 231. The two are fixedly connected. The two ends of the support pipe 215 are supported on the ash removal module frame 204 through bearing seats. The support pipe 215 is connected to the ash removal hose 216. The ash removal hose 216 is evenly coiled on the coiling reel 231 in a spiral manner. The nozzle 217 is located at the wire feeding end of the coiling reel 231. The coiling reel drive 232 drives the coiling reel 231 to rotate around the central axis, thereby driving the nozzle 217 to move up and down inside the boiler.

[0054] The pulley drive unit 232 includes a motor 2321 and a matching small synchronous pulley A 2322, a synchronous belt A2323, and a large synchronous pulley A 2324.

[0055] The lead screw drive system 233 includes a large synchronous pulley B 2331, a synchronous belt B 2332, a small synchronous pulley B 2333, a lead screw 2334, and a pulley 2335.

[0056] Large synchronous pulleys A 2324 and B 2331 are fixed at both ends of the support tube 215, and the three are fixedly connected. The motor 2321 drives the small synchronous pulley A 2322 to rotate, which drives the large synchronous pulley A 2324 to rotate through the synchronous belt A 2323. The large synchronous pulley A 2324 drives the support tube 215 to rotate, thereby rotating the coil wheel 231. The nozzle 217 drives the cleaning hose 216 to move up and down, achieving the purpose of cleaning the entire flue.

[0057] While the coiled wire pulley 231 rotates, the large synchronous pulley B 2331 drives the small synchronous pulley B 2333 to rotate via the synchronous belt B 2332. The small synchronous pulley B 2333 and the lead screw 2334 are relatively fixed. The small synchronous pulley B 2333 drives the lead screw 2334 to rotate. The lead screw 2334 and the pulley 2335 are connected to a ball screw drive structure. Thus, while the lead screw 2334 rotates, the pulley 2335 moves evenly left and right. The wire feeding end of the cleaning hose 216 on the coiled wire pulley 231 is movably connected to the surface of the pulley 2335. The transmission ratio of the screw-driven synchronous belt system is the same as the pitch ratio of the coiled wire pulley and the lead screw. For example, if the spiral pitch of the coiled wire pulley is 40 mm and the lead screw pitch is 10 mm, then the transmission ratio of the screw-driven synchronous belt system is 4:1. This ensures that the left and right movement distance of the pulley 2335 is the same as the left and right distance of the water pipe, providing limiting support for the uniform winding of the cleaning hose 216 on the coil wheel 231 and the up and down movement of the nozzle 217.

[0058] The dust removal module frame 204 includes an aluminum profile and connecting corner frame 241, a conduit 242, and a bottom ring 243.

[0059] The bottom ring 243 is located at the bottom of the aluminum profile and connecting corner frame 241, and corresponds to the dust removal module support roller 102 in the lower part of the outer frame 1. The bottom ring 243 rotates in place on the dust removal module support roller 102. The guide tube 242 is fixed at the bottom of the aluminum profile and connecting corner frame 241 and at the center of the bottom ring 243.

[0060] The cleaning hose 216 passes through the conduit 242 and connects to the nozzle 217. The conduit 242 is fixed on the cleaning module frame 204, providing track support for the up and down movement of the cleaning hose 216.

[0061] In this embodiment, the first rotating component is the transmission gear assembly 202. The second rotating component consists of the bottom ring 243 in the dust removal module frame 204 and the dust removal module support roller 102 in the outer frame 1, with the bottom ring 243 supported on the dust removal module support roller 102. The drive motor 223 drives the small gear 222 to rotate circumferentially around the center of the large gear 221, thereby driving the dust removal module frame 204 to rotate. The large gear 221 in the transmission gear assembly 202 is fixed to the outer frame 1 by bolts, ensuring that the dust removal module 2 rotates stably inside the outer frame 1.

[0062] Furthermore, in this embodiment, the nozzle 217 is a single-nozzle or multi-nozzle nozzle. When the nozzle 217 is a single-nozzle nozzle, it includes a single-nozzle nozzle body 2171, a single fan-shaped nozzle 2172 connected thereto, a partition 2173, an IMU 2174, a wire 2175 (metal cable), and a fixing adhesive 2176. The single-nozzle nozzle body 2171 is connected to the joint of the cleaning hose 216. The partition 2173 is located on the upper part of the single-nozzle nozzle body 2171, forming a sealed space with the top cover of the single-nozzle nozzle body 2171 and the joint of the cleaning hose 216. The IMU 2174 is horizontally located in the sealed space, and the remaining space is filled with the fixing adhesive 2176. One end of the wire 2175 is connected to the IMU 2174, and the other end passes through the cleaning hose 216 for wiring control and data transmission. When the nozzle 217 is a multi-nozzle nozzle, the nozzle 217 includes a multi-nozzle nozzle body 2177 and at least two fan-shaped nozzles 2172 connected thereto, and the multi-nozzle nozzle body 2177 is connected to the joint portion of the cleaning hose 216.

[0063] This embodiment specifically uses a single-nozzle spray head; see the structure below. Figure 5 .

[0064] The single-nozzle nozzle is suitable for applications with long vertical strokes, such as cleaning two or three vertical flues with a vertical distance of over 15 meters. The nozzle 217 is designed as a single-nozzle nozzle body 2171 with a fan-shaped nozzle 2172. Utilizing the impact force of the water flow, the cleaning hose 216 is tilted, and the nozzle tilts downwards, increasing the water volume and spray distance. An inertial measurement unit (IMU) 2174 is mounted at the nozzle to accurately measure the tilt angle of the cleaning hose 216, allowing for cleaning of the lower part of the flue even with a shorter descent distance, thus extending the hose's lifespan. The partition 2173, the top cover of the single-nozzle nozzle body 2171, and the connector of the cleaning hose 216 form a sealed cavity for housing the IMU 2174. The IMU 2174 is fixed horizontally to the partition 2173. The remaining space of the sealed cavity is filled with a fixing adhesive 2176 to secure the IMU 2174. The fixing adhesive 2176 is made of heat-insulating and waterproof material, such as polyurethane (PU) foam. The wire 2175 connected to the IMU 2174 passes through the opening in the connector section of the cleaning hose 216, and then exits from the cleaning hose 216 for wiring control and data transmission. Figure 5 As shown. Different positions of the hose during dust removal are as follows. Figure 7 and Figure 8 As shown in the diagram. Simultaneously, a PID control method is used for precise control of the hose tilt angle; the control principle diagram is shown below. Figure 13 As shown. The system receives a target angle. As an input signal, the target angle The error signal e is obtained by comparing the measured angle α with the actual measured angle. This error signal e is then fed into a PID controller, which calculates an output signal based on a proportional (P), integral (I), and derivative (D) algorithm. This output signal is used to adjust the system state and reduce the error. Simultaneously, based on the relationship between angle α and flow rate, the PID controller calculates a target flow rate. This flow signal is further fed into another PID controller for fine adjustment. The soot remover system compares the received flow signal with the measured flow signal Q and adjusts the pump frequency accordingly. The actual output flow rate Q and the actual measured angle α of the soot remover system are fed back into the system. This feedback information is used to compare with the setpoint, forming a closed-loop control to ensure that the system can operate stably at the target state.

[0065] See Figure 9 The control system 3 includes a water supply valve 301, a water tank 302, an inlet valve 303, a filter 304, a water pump 305, a flow transmitter 306, a pressure transmitter 307, a check valve 308, an electric regulating valve 309, a cooling water inlet main valve 310, several cooling water inlet branch valves 311, a compressed air inlet main valve 312, a pneumatic triplet 313, a compressed air inlet branch valve 314, a solenoid directional valve 315, a pneumatic gate valve 316, several boiler guide pipes 317, and a cooling water inlet 318. Industrial water is connected to the inlet pipe of water tank 302 via water supply valve 301. The outlet of water tank 302 is connected to the inlet pipe of the boiler movable suspended soot remover via inlet valve 303, filter 304, water pump 305, flow transmitter 306, pressure transmitter 307, check valve 308, and electric regulating valve 309. One end of boiler guide pipe 317 is connected to the soot outlet above the boiler, and the other end is connected to pneumatic gate valve 316. Cooling water inlet 318 is located at the bottom of boiler guide pipe 317. Compressed air is connected via compressed air main valve 312, pneumatic triplet 313, compressed air branch valve 314, solenoid directional valve 315, and pneumatic gate valve 316 (this air circuit is referred to as the compressed air system) to control the opening and closing of pneumatic gate valve 316. When soot removal is required, the pneumatic gate valve 316 is opened. The gate valve 316, cleaning hose 216, and nozzle 217 enter the boiler through the boiler guide pipe 317 for cleaning. When cleaning is not required, the pneumatic gate valve 316 is closed. A branch line is branched off from the connecting pipe between the water pump 305 and the flow transmitter 306, and then branched into several pipes to connect to the cooling water inlet 318 of each boiler guide pipe 317. The cooling water inlet main valve 310 is located on the branch pipe, and the cooling water inlet branch valve 311 is located on the branch pipe.

[0066] The dust removal process diagram is as follows Figure 9As shown. Industrial water can be used for ash removal, but tap water or demineralized water can also be used. Industrial water enters water tank 302 through water supply valve 301. Water tank 302 is equipped with a level sensor and a float valve, which enable automatic water replenishment to maintain a high water level. Then, it enters water pump 305 through inlet valve 303 and filter 304. The water is pressurized and transported by pump 305, then metered by flow transmitter 306 and detected by pressure transmitter 307, and enters check valve 308. After being regulated by electric regulating valve 309, it enters the ash remover system, where the mechanical action of the ash remover achieves boiler ash removal.

[0067] The compressed air system is mainly used to control the pneumatic gate valve 316. The compressed air supplied to the site first passes through the main compressed air inlet valve 312, then through the pressure regulating and filtering system of the pneumatic triplet 313, and finally enters each compressed air inlet branch valve 314. The solenoid reversing valve 315 controls the opening and closing of the pneumatic gate valve 316. The pneumatic gate valve 316 is located above the boiler guide pipe 317. In the ash-cleaning state, the pneumatic gate valve 316 is open, allowing the ash-cleaning hose 216 and nozzle 217 to enter the boiler for ash cleaning. After ash cleaning is completed, the pneumatic gate valve 316 closes, isolating the boiler flue gas. A branch water outlet from the outlet of water pump 305 is used for cooling and cleaning the metal cleaning hose 216. The water first passes through the main cooling water inlet valve 310, then through each cooling water inlet branch valve 311, entering the lower part of the boiler guide pipe 317. A water film forms around the metal cleaning hose 216, cooling and protecting it, thus extending its lifespan. Simultaneously, during the ascent of the metal cleaning hose 216 after cleaning, this water flow cleans the hose, reducing corrosion and further extending its lifespan.

[0068] Guide rail 4 is installed on the top platform of the boiler and is made of symmetrical angle steel splicing. It confines the support casters 103 within the track range, such as... Figure 10 and Figure 11 As shown. The hydraulic cleaning device moves along a trajectory, with markers set for the corresponding cleaning positions. The device performs point-to-point cleaning upon reaching the designated position. After completing cleaning at a single point, it moves to the next position for cleaning, and the cleaning is performed sequentially. Figure 12 As shown. The structure is simple and easy to implement, with low cost and minimal maintenance.

[0069] The usage method of the above-mentioned movable suspended soot remover for boilers is as follows:

[0070] During ash removal, the movable suspended ash remover is placed above the boiler, and the pneumatic gate 316 is opened through the compressed air system, so that the nozzle 217 is suspended above the pneumatic gate 316.

[0071] Connect the power supply to motor 2321. Motor 2321 drives small synchronous pulley A 2322 to rotate. Through synchronous belt A 2323, it drives large synchronous pulley A 2324 to rotate. Large synchronous pulley A 2324 drives support pipe 215, which in turn drives coil wheel 231 to rotate. Nozzle 217 drives cleaning hose 216 to move up and down.

[0072] As the coil pulley 231 rotates, the large synchronous pulley B 2331 drives the small synchronous pulley B 2333 to rotate via the synchronous belt B 2332. The small synchronous pulley B 2333 and the lead screw 2334 are relatively fixed. The small synchronous pulley B 2333 drives the lead screw 2334 to rotate. The lead screw 2334 and the pulley 2335 are a ball screw drive structure, so that while the lead screw 2334 rotates, the pulley 2335 moves evenly left and right. The transmission ratio of the screw-driven synchronous belt system is the same as the pitch ratio of the coil pulley and the lead screw. For example, if the spiral pitch of the coil pulley is 40 mm and the lead screw pitch is 10 mm, then the transmission ratio of the screw-driven synchronous belt system is 4:1. This ensures that the left and right movement distance of the pulley 2335 is the same as the left and right distance of the water pipe, providing limiting support for the even winding of the cleaning hose 216 on the coil pulley 231 and the up and down movement of the nozzle 217. The cleaning hose 216 passes through the conduit 242 and connects to the nozzle 217. The conduit 242 is fixed on the cleaning module frame 204, providing track support for the up and down movement of the cleaning hose 216.

[0073] To adjust the angle of the nozzle 217, connect the power supply to the drive motor 223. The drive motor 223 drives the pinion 222 to rotate, and the pinion 222 drives the dust removal module frame 204 to rotate around the center of the large gear 221, which in turn drives the coil system 203 to rotate, thereby driving the dust removal hose 216 and the nozzle 217 to rotate.

[0074] Example 2

[0075] Same as Example 1, see Figure 6 In this embodiment, the nozzle 217 is a multi-nozzle nozzle, specifically a set of two symmetrical fan-shaped nozzles 2172.

[0076] The multi-nozzle nozzle body 2177 is suitable for applications with short vertical strokes, such as cleaning horizontal flues where the vertical distance is less than 5 meters. The nozzle 217 is designed as a multi-nozzle nozzle, with two fan-shaped nozzles 2172 symmetrically installed on the left and right sides. Figure 6 As shown. The cleaning module 2 can clean the entire area by rotating 180°. When cleaning the side panels, the rotation speed is low; when there is no need for cleaning, the rotation speed is high, which saves water, reduces the moisture content of the flue gas, and ensures effective cleaning. If the cleaning requirement is uniform cleaning around the entire perimeter, multiple sets of nozzles can be evenly arranged around the nozzle head. For example, if 4 sets of nozzles are set, the cleaning module 2 only needs to rotate 90°; if 8 sets of nozzles are set, the cleaning module 2 only needs to rotate 45°.

[0077] Application Example 1

[0078] The apparatus of Example 1 is used for cleaning the vertical flues (second and third flues) of the boiler.

[0079] When cleaning vertical flues (second and third flues), nozzle 217 is a single-nozzle nozzle equipped with a fan-shaped nozzle 2172 and an IMU 2174. Upon entering the vertical flue, the drive motor 223 rotates the pinion 222, which in turn rotates the cleaning module frame 204 around the center of the large gear 221. This rotation further drives the coil system 203, which in turn rotates the cleaning hose 216 and nozzle 217. Because nozzle 217 has only one nozzle, the water flow impact force can tilt the cleaning hose 216, causing the nozzle to tilt downwards, increasing the water volume and spray distance. The IMU 2174 at the nozzle accurately measures the tilt angle α of the cleaning hose 216, allowing cleaning of the lower flue area with a shorter descent distance, thus extending the hose's service life. The tilt angle α can be adjusted by changing the water spray volume. When cleaning a nearby wall, reducing the water spray volume decreases the tilt angle α, and the reduced water spray volume also reduces the water flow impact on the nearby wall. When cleaning a distant wall, increasing the water spray volume increases the tilt angle α, allowing the water to reach the distant wall. The larger water volume also compensates for evaporation losses caused by the longer spray distance.

[0080] The formula for calculating the tilt angle α is as follows:

[0081] ,

[0082] in:

[0083] ρ is the density of water (kg / m³) 3 ),

[0084] Q is the water flow rate (m³ / s). 3 / s),

[0085] g is the acceleration due to gravity (m / s²) 2 ),

[0086] μ is the linear density of the hose (mass per unit length, kg / m).

[0087] L is the droop length of the hose (m).

[0088] A1 is the inner cross-sectional area of ​​the hose (m²). 2 ),

[0089] m is the total mass of the nozzle (kg) (including the mass of water inside the cavity).

[0090] A2 is the nozzle cross-sectional area (m²)2 ).

[0091] The PID system diagram for angle and flow control is shown below. Figure 13 As shown, the system receives a target angle. As an input signal, the target angle The error signal e is obtained by comparing the measured angle α with the actual measured angle. This error signal e is then fed into a PID controller, which calculates an output signal based on a proportional (P), integral (I), and derivative (D) algorithm. This output signal is used to adjust the system state and reduce the error. Simultaneously, based on the relationship between angle α and flow rate, the PID controller calculates a target flow rate. This flow signal is further fed into another PID controller for fine adjustment. The soot remover system compares the received flow signal with the measured flow signal Q and adjusts the pump frequency accordingly. The actual output flow rate Q and the actual measured angle α of the soot remover system are fed back into the system. This feedback information is used to compare with the setpoint, forming a closed-loop control to ensure that the system can operate stably at the target state.

[0092] This PID control system achieves precise control of the dust collector through closed-loop regulation, first by comparing the target angle in real time. The system calculates the error based on feedback, then uses a PID algorithm to dynamically adjust the control quantity (including proportional fast response, integral error elimination, and derivative oscillation suppression), and finally outputs an optimized flow command (Q) to drive the dust collector. The system forms a closed loop of "measurement-calculation-execution" through continuous feedback, ensuring operational accuracy and stability.

[0093] For example: A vertical flue has a depth of 9 m from the opening point to the bottom. Using a DN25 metal cleaning hose and a 50° nozzle, with a required hose extension distance of 5 m, through testing and calculation, the target hose tilt angle is determined to be 30°. At this angle, the bottom of the flue can be cleaned. Using the formula, the required water flow rate is 2 m³ / h. 3 / h, when the water flow rate is less than 2 m 3 When the flow rate is [value] / h, the angle is less than 30°, which is inconsistent with the target angle. Through flow adjustment, the hose tilt angle quickly responds to the target angle value, and the hose does not need to be lowered to the bottom to clean the entire flue area. Experiments show that after cleaning, the temperature drop of the flue gas at the vertical flue outlet can reach approximately 50°C, demonstrating a significant cleaning effect.

[0094] Application Example 2

[0095] The apparatus of Example 2 is used for cleaning and ash removal from horizontal flues (superheaters).

[0096] When cleaning the horizontal flue (superheater), nozzle 217 is a multi-nozzle nozzle with two symmetrically installed fan-shaped nozzles 2172. Due to the symmetrical installation of the nozzles and the same water spray volume, the metal hose will remain vertical after entering the horizontal flue. The nozzle 217 is located between two sets of tube banks and rotates under the drive mechanism to perform the cleaning operation. When cleaning the serpentine tube banks, the distance is relatively short, so the water spray volume is reduced; when the nozzle rotates to the water-cooled walls on both sides, the distance is longer, so the water spray volume is increased.

[0097] Application Example 3

[0098] The apparatus of Example 2 is used for cleaning ash from horizontal flues (economizers).

[0099] When cleaning the horizontal flue (economizer), nozzle 217 is a multi-nozzle nozzle with two symmetrically installed fan-shaped nozzles. Due to the symmetrical installation of the nozzles and the same water spray volume, the metal hose will remain vertical after entering the horizontal flue. Nozzle 217 is located between two sets of tube banks and rotates under the drive mechanism to perform the cleaning operation. When cleaning the serpentine tube banks, the distance is relatively short, reducing the water spray volume. When the nozzle rotates to the side walls, since the economizer typically does not have water-cooled walls, cleaning is not required, further reducing the water spray volume. At the same time, the rotation speed of the cleaning module is increased, allowing it to quickly pass through areas that do not require cleaning.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
