Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ash removal from ash hoppers, in particular to a combined anti-clogging and pneumatic ash conveying energy-saving process device for a thermal power plant ash hopper. BACKGROUND

[0002] In the process of thermal power generation, a large amount of fly ash generated by coal combustion needs to be collected and treated by a dust removal system. As a key component of the dust removal system, the ash hopper plays an important role in temporarily storing and conveying fly ash. With the development of thermal power generating units towards large capacity and high parameters, the amount of fly ash discharged has increased significantly, which puts higher requirements on the ash conveying efficiency and anti-clogging performance of the ash hopper. The stability of the ash hopper directly affects the normal operation of the entire dust removal system, and thus relates to the environmental protection indicators and power generation efficiency of the thermal power plant. At present, the ash hopper is widely used in the thermal power industry and is the core link connecting the dust collector and the ash conveying equipment. The level of its technology directly affects the overall operation benefit of the power plant.

[0003] In the prior art, the ash hopper for thermal power generation is usually designed in a conical structure, which utilizes gravity to make the fly ash fall naturally. In order to prevent the fly ash from accumulating and clogging on the inner wall of the ash hopper, a vibrating device is often provided to promote the fly ash to separate from the inner wall through high-frequency vibration. Some ash hoppers are also provided with a heating device to increase the temperature of the fly ash by heating the outer wall of the ash hopper, thereby reducing the viscosity and enhancing the flowability of the fly ash. In the ash conveying process, the pneumatic conveying method is often used to convey the fly ash from the bottom of the ash hopper to the designated location by means of the airflow generated by a fan. Some ash hoppers are also provided with a gate valve or other components at the bottom to control the amount of ash discharged. The combination of these technologies and structures forms the basic operation framework of the existing ash hopper system.

[0004] In actual thermal power generation scenarios, the existing ash hopper technology has many problems. For example, in the operation of the ash hopper of a certain thermal power plant, the use of a heating device to enhance the flowability of the fly ash results in high energy consumption, increasing the operating cost of the power plant. This is because the heating process requires continuous consumption of a large amount of electrical or thermal energy, and the heat utilization efficiency is low. At the same time, the vibrating device and the simple ash cleaning structure cannot completely remove the fly ash adhering to the inner wall, and after a period of operation, the inner wall of the ash hopper will accumulate fly ash, which may cause clogging and affect the continuity of ash conveying. This is because the vibration intensity and the range of ash cleaning are limited, and they cannot cope with the strong adhesion of fly ash. In the ash discharging process, the sealing performance of the traditional ash discharging device is poor, and the fly ash can easily overflow, causing environmental pollution in the plant area, which does not meet the environmental protection requirements. Moreover, the replacement of the ash discharging components is cumbersome, which prolongs the equipment downtime and reduces the work efficiency. This is because the fixed way of the collecting components is not reasonable, and there is a lack of effective stability and quick replacement mechanism. Therefore, the present application provides a combined anti-clogging and pneumatic ash conveying energy-saving process device for a thermal power plant ash hopper to solve the deficiencies in the prior art.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the specification of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0029] Please refer to the drawings in the specification of the present application Figure 1 - the drawings in the specification of the present application Figure 2 The embodiment of the present application provides a combined energy-saving process device for preventing blockage of a power plant ash bucket and pneumatic ash conveying, which comprises an ash bucket 1. The ash bucket 1 is a core component and bears the responsibility of collecting dust falling from a dust collector. A dust charge detection sensor 2 is installed at the top of the ash bucket 1. The dust charge detection sensor 2 adopts an advanced charge induction technology. When dust with a certain negative charge passes near the sensor probe, a weak charge signal will be induced. The signal is output after being processed by an internal circuit, which can monitor the charge condition and concentration change of dust in the ash bucket 1 in real time and provide data support for subsequent ash removal operation. For example, when the dust concentration is too high or the charge is abnormal, the relevant equipment can be started in time to remove the ash. The bottom end of the dust charge detection sensor 2 penetrates the inner wall of the ash bucket 1 and extends into the interior of the ash bucket 1, which can accurately obtain dust information in the ash bucket 1.

[0030] The outer side of the ash bucket 1 is fixedly connected with an air inlet pipe 3, and the connecting port of the air inlet pipe 3 is in communication with the inside of the ash bucket 1, for conveying fluidized air into the ash bucket 1. The outer side of the air inlet pipe 3 is provided with a anti-blocking device 4, which ionizes the particles in the fluidized air into negative particles by the principle similar to that of an electrostatic generator. After the ash in the dust collector enters the ash bucket 1, the negative particles generated by the anti-blocking device 4 are blown into the inside of the ash bucket 1 due to the certain amount of negative charge itself, and according to the principle that like charges repel each other, the repulsive force between the charged ash particles is further increased, effectively strengthening the dispersion and fluidity between the ash particles, achieving the effect of increasing the dispersion and fluidity between the ash particles without heating the outer wall of the ash bucket 1, reducing the accumulation and blocking risk of the ash particles in the ash bucket 1.

[0031] The other side of the outer side of the ash bucket 1 is provided with a vibration motor 5, and when the vibration motor 5 works, the eccentric blocks at both ends of the motor inside shaft rotate at high speed to generate centrifugal force, so that the whole ash bucket 1 generates high-frequency vibration. The vibration frequency and amplitude can be adjusted according to the actual working condition, for example, for the ash with higher viscosity, the vibration frequency and amplitude can be appropriately increased. Through vibration, the dust adhering to the inner wall of the ash bucket 1 can be shaken up, assisting the subsequent ash removal operation, so that the dust can be more easily removed.

[0032] The inside of the ash bucket 1 is provided with an ash removal mechanism 6, which cooperates with the anti-blocking device 4 and the vibration motor 5 to perform the ash removal operation. The ash removal mechanism 6 includes a reduction motor 601, which can provide stable and controllable power output, and the output end of the reduction motor 601 is fixedly connected with a reciprocating screw rod. When the reduction motor 601 is started, the reciprocating screw rod is driven to rotate. One end of the reciprocating screw rod is rotatably connected with the inner top wall of the ash bucket 1, to ensure the stability of the screw rod during rotation. The inside of the ash bucket 1 is fixedly connected with a guide rod 602, which is arranged in parallel with the reciprocating screw rod. The outside of the reduction motor 601 and the guide rod 602 is provided with a T-shaped moving block 603, the outer side of the reciprocating screw rod is threadedly connected with the inside of the T-shaped moving block 603, and the inside of the T-shaped moving block 603 is slidably connected with the outside of the guide rod 602. In this way, when the reciprocating screw rod rotates, the T-shaped moving block 603 will make up-and-down reciprocating linear motion along the reciprocating screw rod under the guidance of the guide rod 602.

[0033] The outer side of the T-shaped moving block 603 is provided with four adaptive brush assemblies, two of which are higher than the other two, which can better cover the inner wall of the ash bucket 1 at different heights. The adaptive brush assembly includes two telescopic rods 604, one side of which is fixedly connected to the outer side of the T-shaped moving block 603, and the outer telescopic rod 604 is sleeved with a spring 605, and one end of the telescopic rod 604 is fixedly connected with an ash removal plate 606. One end of the spring 605 is fixedly connected with the outer side of the T-shaped moving block 603, and the other end is fixedly connected with one side of the ash removal plate 606. When the T-shaped moving block 603 drives the adaptive brush assembly to move up and down, it encounters different shapes or obstacles in the inner wall of the ash bucket 1, the telescopic rod 604 can be telescopic adjusted under the action of the spring 605, so that the ash removal plate 606 can always be in good contact with the inner wall of the ash bucket 1, and the dust removal effect is ensured.

[0034] The inner side of the ash removal plate 606 is provided with a sliding groove 608, and the inner side of the sliding groove 608 is fixedly connected with a fixed rod 613. The outer side of the fixed rod 613 is sleeved with two springs 614, and the outer side of the fixed rod 613 is slidably connected with a sliding plate 609. The proximal ends of the two springs 614 are fixedly connected with the fixed rod 613 at the inner side of the sliding groove 608, and the other ends are fixedly connected with one end of the sliding plate 609. The outer side of the ash removal plate 606 is fixedly connected with a plurality of brushes 607, and one side of the sliding plate 609 is fixedly connected with a plurality of brushes 610. The inner wall of the sliding groove 608 is provided with a limiting groove 612 on both sides, and the outer side of the sliding plate 609 is slidably connected with the inner side of the sliding groove 608. The outer sides of the two sides of the sliding plate 609 are fixedly connected with a limiting strip 611, and the outer side of the limiting strip 611 is slidably connected with the inner side of the limiting groove 612. Because the ash bucket 1 is in the shape of an inverted truncated cone, when the adaptive brush assembly moves downward, the two sliding plates 609 will slide to the middle position of the ash removal plate 606 under the action of the smaller outer space, overcoming the elastic force of the spring 614 to adapt to the external space. The cooperation of the brushes 607 and 610 can ensure that the inner wall of the ash bucket 1 can be basically covered, whether it is the upper wider area or the lower narrower area of the inner wall of the ash bucket 1, it can effectively brush off the firmly adhered dust, and cooperate with the anti-blocking device 4 and the vibration motor 5 to achieve better dust removal effect.

[0035] The bottom of the ash bucket 1 is provided with an ash discharging mechanism 7. The ash discharging mechanism 7 comprises a fixed cylinder 701, the top of which is fixedly connected to the bottom of the ash bucket 1 as a dust discharging channel. An annular groove 702 is formed on the outer side of the fixed cylinder 701 for mounting the components of the cloth cylinder bag 703. The fixed cylinder 701 is externally sleeved with the cloth cylinder bag 703 for collecting the dust discharged from the ash bucket 1. The cloth cylinder bag 703 is made of a material with good high-temperature resistance, corrosion resistance and air permeability, which can effectively filter dust and prevent dust from flying out. The outer side of the cloth cylinder bag 703 is provided with a steel wire rope 704, which is attached to the outer side of the cloth cylinder bag 703 and located inside the annular groove 702. By winding the steel wire rope 704 around the annular groove 702, the position of the cloth cylinder bag 703 can be stabilized to prevent displacement or falling of the cloth cylinder bag 703 during ash discharging.

[0036] An assembly groove 706 is formed on the outer side of the fixed cylinder 701 above the annular groove 702, and a rotating disc 707 is rotatably connected inside the assembly groove 706. A circular hole two 708 is formed in the rotating disc 707, and a circular hole one 705 is formed in the fixed cylinder 701. The circular hole two 708 is in communication with the circular hole one 705 and the through hole at the bottom of the ash bucket 1. When ash needs to be discharged, the rotating disc 707 is actuated to make the circular hole two 708 in the rotating disc 707 communicate with the circular hole one 705. At this time, the dust in the ash bucket 1 is blown into the cloth cylinder bag 703 for collection under the action of fluidized wind through the circular hole one 705 and the circular hole two 708. After collection is completed, the cloth cylinder bag 703 can be removed and replaced to remove the dust in the ash bucket 1, which is simple and efficient.

[0037] Specifically, the dust in the dust collector still has a certain amount of negative charge after entering the ash bucket 1, at this time the anti-blocking device 4 installed on the air inlet pipe 3 starts to work, ionizes the fluidization air into negative particles and blows into the ash bucket 1 through the air inlet pipe 3, and further increases the repulsive force between the charged ash particles by using the principle of mutual repulsion between the charged ash particles. This repulsive force can effectively break the adsorption force between the ash particles and strengthen the dispersion and flowability of the ash particles, thereby achieving the same effect of increasing the dispersion and flowability of the ash particles without heating the outer wall of the ash bucket 1, avoiding the energy consumption caused by the traditional heating method, and reducing the accumulation of ash particles on the inner wall of the ash bucket 1. Then start the vibration motor 5, when the vibration motor 5 works, the vibration force generated by the vibration motor 5 is transmitted to the outer wall of the ash bucket 1, so that the ash bucket 1 as a whole produces high-frequency vibration. This vibration can make the dust attached to the inner wall of the ash bucket 1 receive a strong vibration force, thereby being shaken off the inner wall, clearing the way for subsequent dust removal operation; and simultaneously start the speed reducer 601, the speed reducer 601 drives the reciprocating screw rod to rotate. Since the reciprocating screw rod is threadedly connected with the T-shaped moving block 603, and the T-shaped moving block 603 cannot rotate with the reciprocating screw rod under the limitation of the guide rod 602, the T-shaped moving block 603 will make up-and-down reciprocating linear motion along the reciprocating screw rod and the guide rod 602, thereby driving the adaptive brush assembly to move up and down. Because the ash bucket 1 as a whole presents an inverted truncated cone shape, during the downward movement of the adaptive brush assembly, the outer space gradually becomes smaller, and the two sliding plates 609 will slide to the middle position of the dust removal plate 606 under the action of this space change, so as to adapt to the shape change of the inner wall of the ash bucket 1. The cooperation of the brush 1 607 and the brush 2 610 can ensure that the inner wall of the ash bucket 1 can be basically covered, and the upper, middle and lower parts of the inner wall of the ash bucket 1 can be effectively swept by the brushes, thereby better brushing off the dust that is firmly adhered. The cooperation of the dust removal mechanism 6, the anti-blocking device 4 and the vibration motor 5 greatly improves the dust removal effect and keeps the inner wall of the ash bucket 1 clean.

[0038] Working principle: The dust in the dust collector enters the ash bucket 1 still with a certain amount of negative charge, the anti-blocking device 4 installed on the air inlet pipe 3 ionizes the fluidization air into negative particles and blows into the inside of the ash bucket 1, according to the principle of mutual repulsion between negative charged particles, further increase the repulsive force between the charged particles, strengthen the dispersion and flowability between the particles, achieve the effect of increasing the dispersion and flowability between the particles without heating the outer wall of the ash bucket 1, then start the vibration motor 5 to vibrate the outer wall of the ash bucket 1, so that the whole ash bucket 1 vibrates, the dust attached to the inner wall of the ash bucket 1 is shaken up, and the speed reducer motor 601 is started to drive the reciprocating screw rod, so that the T-shaped moving block 603 drives the adaptive brush assembly to move up and down, the ash bucket 1 as a whole presents a shape of inverted truncated cone, therefore when the adaptive brush assembly moves down, the two sliding plates 609 will slide to the middle position of the dust removal plate 606 to adapt to the external space, and the cooperation of the brush one 607 and the brush two 610 can ensure that the inner wall of the ash bucket 1 can be basically covered, so that the dust adhered firmly can be brushed off better, and the cooperation of the anti-blocking device 4 and the vibration motor 5 realizes better dust removal effect; in addition, the cloth cylinder bag 703 is sleeved outside the fixed cylinder 701, and the steel wire rope 704 is wound around the position of the annular groove 702, so that the position of the cloth cylinder bag 703 is stable, then the rotating disc 707 is actuated to make the circular hole two 708 in the inside thereof communicate with the circular hole one 705, so that the dust in the inside of the ash bucket 1 is blown into the inside of the cloth cylinder bag 703 for collection, finally the cloth cylinder bag 703 is taken off and replaced to remove the dust in the inside of the ash bucket 1.

[0039] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, the scope of the present application being defined by the appended claims and their equivalents.
