Description

Technical Field

[0001] This utility model relates to the technical field of waste incineration equipment, and in particular to a dust collector diversion pipe anti-clogging device. Background Technology

[0002] In waste-to-energy incineration, dust collectors, as flue gas purification devices, use distribution pipes to evenly distribute dust-laden airflow to each dust collection unit. However, the flue gas produced by waste incineration contains a large amount of unburned organic matter, chlorides, sulfates, and other complex components. After these substances volatilize at high temperatures, they cool and condense into highly viscous dust within the low-temperature distribution pipes, easily adhering to the inner walls of the pipes. Simultaneously, the dust particles have a wide range of sizes; extremely fine particles are easily suspended, while larger particles easily settle. The interweaving and bridging of dust particles of different sizes leads to blockages in the distribution pipes.

[0003] Currently, most existing technologies for preventing blockage in dust collector diversion pipes employ pulse jet cleaning technology, which removes dust through the instantaneous impact of compressed air; some scenarios introduce acoustic cleaning technology, which uses acoustic resonance to detach dust from the pipe wall.

[0004] However, the existing technical solutions have the following problems in practical applications:

[0005] 1) Because pulse jet cleaning has limited effectiveness in removing highly viscous dust, the airflow impact force is difficult to overcome the strong adhesion between dust and pipe wall, which easily leads to the accumulation of residual dust.

[0006] 2) Due to the influence of bends and branches in the diversion pipe, the sound wave propagation coverage is uneven, and the dust in some areas is not thoroughly cleaned. Utility Model Content

[0007] The purpose of this invention is to provide a dust collector diversion pipe anti-clogging device to alleviate the technical problems of dust accumulation and incomplete cleaning in the prior art.

[0008] The dust collector diversion pipe anti-clogging device provided by this utility model includes: flue, diversion pipe, manhole door, vibrator, rectifier plate and control components;

[0009] The flue is connected to multiple branch pipes; a rectangular hole is opened in the middle of the flue, and a manhole door is hinged to the outer periphery of the rectangular hole; each branch pipe is equipped with a vibrator on its outer wall to make the branch pipe vibrate at high frequency.

[0010] Each diverter is equipped with a rectifier plate near the flue entrance; the outer periphery of the rectifier plate is in contact with the inner wall of the diverter plate, and several holes are evenly opened on the surface of the rectifier plate to stabilize the airflow in the diverter plate.

[0011] The control components are connected to the signal of the vibrator.

[0012] Furthermore, the vibrator includes a motor and an eccentric wheel; the motor is coaxially connected to the eccentric wheel via a coupling and is used to transmit vibration to the outer wall of the diverter.

[0013] Furthermore, the control components include a pressure sensor and a controller with signal connections. The pressure sensor is arranged on the inner wall of each shunt pipe, and the output of the controller is connected to a motor.

[0014] Furthermore, multiple rappers are installed on the outer wall of each diversion pipe. The multiple rappers are evenly distributed at intervals along the gas flow direction of the diversion pipe, and the eccentric wheels of the multiple rappers rotate synchronously.

[0015] Furthermore, a manhole door includes a door body, hinges, and latches;

[0016] The door is hinged to the outer wall of the flue, and a buckle is provided at the end of the door away from the hinge for opening and closing the door.

[0017] Furthermore, the opening and closing direction of the door forms an angle of 45° to 90° with the axis of the flue.

[0020] Beneficial effects:

[0021] The dust collector diversion pipe anti-clogging device provided by this utility model includes a flue connected to multiple diversion pipes; a rectangular hole is opened in the middle of the flue, and a manhole door is hinged to the outer periphery of the rectangular hole; a vibrator is installed on the outer wall of each diversion pipe to make the diversion pipe vibrate at high frequency; a rectifier is installed at the inlet of each diversion pipe near the flue; the outer periphery of the rectifier is attached to the inner wall of the diversion pipe, and several holes are evenly opened on the surface of the rectifier to stabilize the airflow in the diversion pipe; the control component is connected to the vibrator for signal connection.

[0022] This utility model features a manhole door hinged in the middle of the flue, which opens flexibly, allowing staff to quickly enter the flue for inspection and maintenance. The hinged design reduces the number of disassembly steps and improves operational convenience.

[0023] Each diversion pipe is equipped with a rapper, whose high-frequency vibrations directly act on the pipe wall, breaking down the adhesion between dust and the pipe wall. This is particularly effective for cleaning sticky dust, reducing the risk of single-pipe blockage and ensuring the smooth flow of the diversion system. The flow rectifier plate at the diversion pipe inlet has evenly spaced perforations to rectify and stabilize the airflow entering the pipe, reducing turbulence and eddies, resulting in more uniform dust distribution. This, combined with the rapper, improves cleaning efficiency and prevents secondary dust accumulation due to turbulent airflow.

[0024] By connecting the control components to the rapping machine via signal, the machine can start and stop automatically, reducing manual intervention and improving the stability and energy efficiency of equipment operation. Attached Figure Description

[0037] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] The present invention provides a dust collector diversion pipe anti-clogging device, comprising: flue 1, diversion pipe 2, manhole door 3, vibrator 4, rectifier plate 5, and control component 6;

[0039] The flue 1 is connected to multiple branch pipes 2; a rectangular hole is opened in the middle of the flue 1, and a manhole door 3 is hinged to the outer periphery of the rectangular hole; each branch pipe 2 is equipped with a vibrator 4 on its outer wall to make the branch pipe 2 vibrate at high frequency.

[0040] Each diversion pipe 2 is equipped with a rectifier plate 5 near the inlet of the flue 1; the outer periphery of the rectifier plate 5 is in contact with the inner wall of the diversion pipe 2, and several holes are evenly opened on the surface of the rectifier plate 5 to stabilize the airflow in the diversion pipe 2.

[0041] The control component 6 is connected to the rapper 4 via signal.

[0042] Specifically, such as Figure 1 As shown, multiple diversion pipes 2 are evenly connected to the sidewall of flue 1 along the circumference or axis. The axis of the diversion pipes 2 is arranged at an angle of 45° to 60° with the axis of flue 1, and transition pipes are used at the connection to reduce airflow resistance. A rectangular inspection hole is opened in the middle of flue 1. The outer periphery of the hole is hinged to a manhole door 3. The door can rotate around the hinge to open and close. When closed, the edge of the door and the sealing groove around the rectangular hole are tightly fitted by a rubber sealing ring. Vibrators 4 are equidistantly installed on the outer wall of each diversion pipe 2 along the circumference. The vibrators 4 are welded to the outer wall of the diversion pipe 2 by L-shaped brackets or directly bolted. The vibration direction is perpendicular to the axis of the diversion pipe 2. Near the inlet of flue 1, each diversion pipe 2 is equipped with a rectifier plate 5 fixed to the inner wall of the pipe. Several holes are evenly distributed on the surface of the rectifier plate 5. The axis of the holes is consistent with the airflow direction in the diversion pipe 2. The control component 6 is connected to the drive device of each vibrator 4 through a shielded cable or wireless signal.

[0043] The hinged connection between the rectangular hole and the manhole door 3 allows maintenance personnel to quickly open the door and enter the flue 1 for cleaning or component maintenance. The fit between the rubber sealing ring and the sealing groove ensures airtightness during operation and prevents flue gas leakage. The vibrator 4 efficiently transmits high-frequency vibration force to the wall of the diversion pipe 2, causing the diversion pipe 2 to vibrate at high frequency. Since the adhesion between sticky dust and the pipe wall is easily broken under high-frequency vibration, the dust will be shaken off; effectively breaking the adhesion between sticky dust and the pipe wall, achieving efficient cleaning and anti-clogging; the perforated structure of the rectifier plate 5 can rectify and stabilize the airflow entering the diversion pipe 2, reducing turbulence and eddies, making the incoming airflow more uniform. Compared with the traditional pulse jet cleaning which is not effective for sticky dust, and the problem of incomplete cleaning in complex structures by sonic cleaning, this utility model can more comprehensively and efficiently remove dust in the diversion pipe 2, significantly reduce the risk of clogging, ensure the long-term stable operation of the dust collector, and improve dust removal efficiency. Furthermore, the two work together. On the one hand, a good airflow distribution helps the mechanical rapping of the vibrator 4 to function effectively, ensuring that the dislodged dust is carried away smoothly. On the other hand, the dust removal by the vibrator 4 also helps maintain stable airflow, preventing dust accumulation from affecting the airflow. Through this collaborative design, the overall performance of the dust collector is improved. This not only optimizes the anti-clogging effect of the diversion pipe but also makes the entire dust collection system operate more efficiently and stably, extending the service life of the equipment.

[0044] With the addition of control component 6, automated and intelligent control is achieved, eliminating the need for frequent manual intervention. This allows the system to better adapt to complex and changing working environments, improve the stability and reliability of equipment operation, and reduce manual maintenance costs.

[0045] In an embodiment of this utility model, the vibrator 4 includes a motor and an eccentric wheel; the motor is coaxially connected to the eccentric wheel via a coupling and is used to transmit vibration to the outer wall of the diversion pipe 2.

[0046] The control component 6 includes a pressure sensor 601 and a controller 602 connected by signals. The pressure sensor 601 is arranged on the inner wall of each shunt pipe 2, and the output of the controller 602 is connected to a motor.

[0047] Multiple rappers 4 are installed on the outer wall of each diversion pipe 2. The multiple rappers 4 are evenly distributed at intervals along the gas flow direction of the diversion pipe 2, and the eccentric wheels of the multiple rappers 4 rotate synchronously.

[0048] Specifically, such as Figure 1 , Figure 4 As shown, the motor and eccentric wheel inside the vibrator 4 are coaxially connected via a coupling. The eccentric wheel is located at the end of the motor output shaft and close to the outer wall of the diversion pipe 2, ensuring that the vibration energy is directly transmitted to the pipe wall. The pressure sensor 601 is embedded in the upper-middle position (near the inlet) of the inner wall of each diversion pipe 2, flush with the pipe wall to avoid interfering with the airflow. The controller 602 is connected to the pressure sensor 601 via a signal line and to the motor of each vibrator 4 via a control line. Multiple vibrators 4 are arranged at equal intervals along the gas flow direction of the diversion pipe 2 (from the inlet to the outlet), and the rotation phase of all eccentric wheels is the same, ensuring that the vibration direction is consistent.

[0049] The coaxial coupling between the motor and the eccentric wheel acts directly on the outer wall of the diversion pipe 2, breaking the adhesion between the dust and the pipe wall. The pressure sensor 601 is arranged upstream of the inner wall of the diversion pipe 2, which can monitor the changes in airflow pressure in real time. When dust accumulation causes abnormal pressure inside the pipe, the controller 602 immediately triggers the motor to start rapping, realizing the "on-demand dust removal" response and avoiding ineffective energy consumption. Multiple rappers 4 are evenly distributed along the airflow direction, covering the entire length of the diversion pipe 2, avoiding the limited area of ​​action of a single rapper. The phase synchronization of the eccentric wheel makes the vibration of each rapper 4 superimpose to form a continuous vibration wave, enhancing the dust removal effect on the long-distance diversion pipe 2, preventing dust from accumulating in the rapping interval area, and avoiding the mutual cancellation of vibration energy caused by phase difference.

[0050] It should be noted that the vibratory beater 4 of this utility model can be a YZS series vibration source three-phase asynchronous motor or other vibration motor, so as to perform high-frequency vibration to prevent blockage of the silo or pipeline.

[0051] In an embodiment of this utility model, the manhole door 3 includes a door body 301, a hinge 302, and a buckle 303;

[0052] The door 301 is hinged to the outer wall of the flue 1 via a hinge 302. A buckle 303 is provided at the end of the door 301 away from the hinge 302 for opening and closing the door 301.

[0053] The opening and closing direction of the door 301 forms an angle of 45° to 90° with the axis of the flue 1.

[0054] The outer wall of door 301 is covered with a ceramic fiber layer.

[0055] The door body 301 has multiple air chambers spaced apart along the thickness direction of the door body.

[0056] Specifically, such as Figure 2 , Figure 3 As shown, the door 301 is hinged to one side of the rectangular hole on the outer wall of the flue 1 via a hinge 302. The axis of the hinge 302 is parallel to the axis of the flue 1, allowing the door 301 to open outward around the hinge 302. A buckle 303 is provided on the end of the door 301 away from the hinge 302 (right side), which cooperates with the buckle base on the outer wall of the flue 1 to realize the opening and closing of the door 301. Multiple air chambers are provided inside the door 301. The chambers are separated by partitions parallel to the surface of the door. The partitions and the inner and outer surfaces of the door form a closed space.

[0057] The combined design of hinge 302 and buckle 303 enables quick operation of manhole door 3. Operators can open and close the door by rotating the door body 301 and engaging the buckle 303 without tools, improving maintenance efficiency. The ceramic fiber layer on the outer wall of door body 301 can prevent heat loss to the outside, while the internal air chamber uses the low thermal conductivity of air to form a heat insulation layer. The double insulation structure enables door body 301 to maintain good heat preservation under high temperature conditions, reducing heat loss inside the dust collector and maintaining the temperature.

[0058] Based on the above embodiments, the specific working process of the dust collector diversion pipe anti-clogging device provided by this utility model is as follows:

[0059] As dust gradually accumulates inside the diversion pipe 2, the pressure sensor 601 of the control component 6 monitors the pressure changes inside the pipe. If the pressure is abnormal, the controller 602 triggers the start of the vibrator 4. The motor of the vibrator 4 drives the eccentric wheel to rotate at high speed, generating high-frequency vibration force that is transmitted to the outer wall of the diversion pipe 2, causing the pipe wall to vibrate at high frequency, breaking the adhesion between the sticky dust and the pipe wall, and the dust is shaken off. At the same time, the stable airflow of the rectifier plate 5 promptly carries away the shaken-off dust, preventing secondary accumulation. When maintenance is required, the staff can open the manhole door 3 by rotating the hinge 302 without tools.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
