However, there are many deficiencies in the prior art: Plate-type electric heating has problems such as short heating life and unstable effect, and it is difficult to continuously ensure the fluidity of the material in the ash hopper; Steam heating has high energy consumption, and water leakage from the steam trap is likely to cause safety accidents, resulting in coal ash caking and poor ash flow. Moreover, it is significantly restricted by parameters, there is a risk of leakage, high requirements for steam quality, and a large amount of maintenance work; At the same time, electric heating also has defects such as high power and low heat conversion rate.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] The ash hopper of the anti-blocking dust collector of the present invention, as Figure 1 shown, includes an ash hopper of a dust collector. The inner wall of the ash hopper of the dust collector is coated with a nano-ceramic material coating 1. By coating the nano-ceramic material coating 1, the contact surface between the ash powder and the ash hopper is smoother, the friction coefficient is small, and the ash flow is smooth. Its unique wear resistance, corrosion resistance, high temperature resistance, and insulation properties can better protect the ash hopper of the dust collector.
[0018] The nano-ceramic material coating 1 uses nano-ceramic materials. The nano-ceramic materials are specifically high-molecular nano materials developed by the method of hetero-element ternary copolymer emulsion polymerization. Among them, the high-molecular nano materials use ionic compounds and partially artificially synthesized covalent compounds. Ionic bonds and covalent bonds belong to strong binding bonds, and the binding system forms chemical bonds due to the adoption of composite strengthening measures and special treatments, so the strength and stiffness are very large, and it can effectively resist high-speed impact force and shear stress and has high wear resistance. Moreover, the high-molecular nano materials have the characteristics of acid resistance and alkali resistance, and can effectively resist the action of environmental media and various chemical corrosions. The high-molecular nano materials can prevent sticky fly ash from adhering to the inner wall of the ash hopper, and at the same time can effectively prevent the penetration of moisture, grease, etc., keep the material dry at all times, and improve the service life. During use, due to the continuous scouring of the falling ash flow, the material can remain clean without ash, ensuring the smoothness of the ash flow. The surface of the material is smoother than the surface of the original steel ash hopper, and the surface has a low friction coefficient, reducing the angle of repose of the ash hopper surface and making the ash flow smoother.
[0019] An anti-blocking device 2 is installed at the inlet of the fluidizing air pipeline of the dust collector hopper. The anti-blocking device 2 ionizes the fluidizing air in the fluidizing air pipeline and sends a negative ion beam into the fluidizing air pipeline, so that the fly ash is charged with negative ions. The amount of electricity of the negatively charged fly ash entering the hopper is not the same. Although there is a repulsive force between the fly ashes, there are fly ashes with high specific resistance and fly ashes with low specific resistance, and the difference in the repulsive force is very large. In addition, due to the uneven flue gas temperature, the specific resistance of some fly ashes is too low. By charging the fluidizing air with negative ions, the fly ash collides with the negative ions and is negatively charged, increasing the repulsive force between the fly ashes, preventing them from sticking together, strengthening the dispersion of the dust, and preventing the fly ash from sticking. Different from the traditional steam heating or electric heating methods, the method of ionizing the fluidizing air in the fluidizing air pipeline by the anti-blocking device 2 has no leakage risk, does not need to consider the length of the heating life, the service life of the whole device is longer, and by sending the negative ion beam into the fluidizing air pipeline, the fly ash is charged with negative ions, increasing the repulsive force between the fly ashes, and the anti-sticking effect is more stable.
[0020] The dust particle charge quantity detection and control system 3 includes a charge quantity detection sensor. The output end of the charge quantity detection sensor is connected to the input end of the signal conditioning circuit. The output end of the signal conditioning circuit is connected to the input end of the A / D converter. The output end of the A / D converter is connected to the data interface of the DSP processor. The control signal output end of the DSP processor is connected to the communication interface module. The dust particle charge quantity detection and control system 3 also includes a power supply module. The output end of the power supply module is respectively connected to the power supply interfaces of the charge quantity detection sensor, the signal conditioning circuit, the A / D converter, the DSP processor, and the communication interface module. The DSP processor is connected to the anti-blocking device 2 through the communication interface module.
[0021] During the flow of the flue gas, the dust particles collide and rub against each other and against the pipeline, and the dust particles are charged with a certain amount of electricity and generate a certain charge field. When passing through the charge quantity detection sensor, an equal amount of induced charge is generated on the surface of the sensor. The charged dust particles flow near the sensor and can generate an induced current. The charge quantity of the dust is accurately measured through the power spectral density technology and digital signal processing technology, and the negative ion output quantity of the anti-blocking device 2 is adjusted according to the measured charge quantity, preventing insufficient dispersion due to too small charge quantity or suspension of charged particles caused by too large charge quantity, resulting in a reduction in the dust removal efficiency.
[0022] The signal conditioning circuit amplifies, filters and processes the weak analog signal output by the charge detection sensor to improve the signal quality and stability, facilitating subsequent A / D conversion. The A / D converter converts the conditioned analog signal into a digital signal for the DSP processor to process. The DSP processor receives the digital signal output by the A / D converter, processes and analyzes it, calculates the charge quantity value of the fly ash, and makes corresponding control decisions based on the magnitude of the charge quantity. When the DSP processor detects that the charge quantity is too low, it remotely controls the connection of the anti-blocking device 2 to add negative ion charges to the fluidizing air. The fly ash collides with the negative ions and becomes negatively charged, increasing the repulsive force between the fly ash particles and preventing them from sticking together.
[0023] A standby clogging removal device is installed on the outer wall of the dust hopper of the dust collector. In special cases, when caking or ash blockage occurs inside the dust hopper, the standby clogging removal device can be started for accident handling, and the clogging removal device is adjusted according to the degree of caking and ash blockage.
[0024] Among them, the standby clogging removal device includes a vibrating motor 4, an air cannon 5 and a pulse clogging removal device 6.
[0025] The vibrating motor 4 is fixed on the motor bracket, and the motor bracket is installed on the outer wall of the dust hopper. The output shaft of the vibrating motor 4 is connected to the eccentric block through a coupling, and the rotation of the eccentric block generates vibration. When the vibrating motor 4 is started, the eccentric block rotates to generate vibration, which is transmitted to the dust hopper wall through the motor bracket, loosening and falling off the caked material adhering to the dust hopper wall. The control circuit of the vibrating motor 4 is connected to the control signal output end of the DSP processor through the communication interface module. The vibration frequency and amplitude of the vibrating motor 4 can be adjusted by the DSP processor. Appropriate vibration parameters are selected according to the degree of ash blockage to achieve precise clogging removal. The vibrating motor 4 and the DSP processor, as Figure 2 shown, the start and stop of the vibrating motor 4 are controlled by the DSP processor in the dust particle charge quantity detection and control system 3.
[0026] The air cannon 5 is arranged outside the dust hopper near the discharge port, which can effectively prevent the discharge port from being blocked and ensure the smooth discharge of materials. The air cannon 5 includes a gas storage tank, an electromagnetic pulse valve, a cannon body and a nozzle. The gas storage tank is connected to the compressed air source through a pipeline and is used to store high-pressure air. The electromagnetic pulse valve is installed on the pipeline between the gas storage tank and the cannon body. The electromagnetic pulse valve is connected to the control signal output end of the DSP processor through the communication interface module, as Figure 2 shown, and its opening and closing are controlled by the DSP processor in the dust particle charge quantity detection and control system 3. The cannon body is fixed on the outer wall of the dust hopper, and the nozzle extends into the dust hopper and faces the part where ash blockage is likely to occur. When the electromagnetic pulse valve is opened, the high-pressure air in the gas storage tank is instantaneously released, forming a strong airflow impact force through the cannon body and the nozzle to impact and break large caked blocks, making the materials resume flow.
[0027] The pulse plugging removal device 6 mainly includes a pulse generator, a pulse pipeline, and a pulse nozzle. The pulse generator is connected to a compressed air source through a pipeline and can generate customized pulsed airflows. The pulse generator is connected to the control signal output end of the DSP processor through a communication interface module. The pulse pipeline transports the pulsed airflows generated by the pulse generator to the pulse nozzle. The pulse nozzle is installed on the upper half of the side wall of the ash hopper. As Figure 2 shown, it is controlled to be turned on and off by the DSP processor in the soot particle charge amount detection and control system 3. The pulse pipeline transports the pulsed airflows generated by the pulse generator to each pulse nozzle. The pulse nozzle extends into the interior of the ash hopper. When the pulsed airflows are ejected, the pulse nozzle guides high-pressure, large-capacity, and 360-degree diffused compressed air pulses between the material and the container wall during each powerful pulse, which can directly and effectively act on the surface of the filter bag, quickly and thoroughly blow off the attached dust, enabling the filter bag to obtain a good dust cleaning effect and ensuring the filtration efficiency and operation stability of the dust collector.
