Description

Technical Field

[0001] The invention relates to the technical field of dust collectors, in particular to an anti-blocking and heat-free device for a dust collector hopper. Background Art

[0002] Coal is the largest cost for thermal power companies, accounting for about 70% of the total cost of power generation, which directly affects the efficiency level and competitiveness of the company. In recent years, the ash powder after burning in the ash hopper will cause agglomeration due to low temperature, humidity and other reasons, resulting in poor ash discharge and possible safety accidents. In order to prevent arching and acid dew, the ash hopper needs heating, insulation and fluidizing air input measures, and has been widely used in the dust collector system of thermal power plants, which plays the role of heating, insulation and acid dew prevention, and ultimately achieves the working requirements of preventing ash sticking, ash blockage and arching. However, energy consumption through heating in any way is inevitable. At present, when the country is paying more and more attention to the energy-saving concepts of carbon peak and carbon neutrality, it can solve the problems faced by the ash hopper well, increase the fluidity of ash to a certain extent, and save energy, or even zero energy consumption, which has become the development direction of technology.

[0003] At present, the main solution to the problem of preventing blockage and acid dew agglomeration in the ash hopper in the domestic thermal power industry is to lay a heating device on the outer wall of the ash hopper and add an insulation layer to prevent temperature loss. There are two main heating methods: 1) Steam heating: that is, a high-temperature steam pipe is laid through the outer wall of the ash hopper, and the heat loss of the insulated ash hopper is compensated by dissipating heat through the steam heating pipe.

[0004] 2) Electric heating: Electric heating is further divided into plate type electric heating, tube type electric heating and sheet type electric heating. The difference is that the heating elements are different, the heating control methods are different, and the energy consumption is also different. However, the heating method has obvious disadvantages: high energy consumption, short equipment life, low heat conversion efficiency, and high maintenance.

[0005] Steam heating is restricted by steam parameters. It can neither maintain a high temperature nor control the required temperature. It is difficult to meet the temperature maintenance needs of various media. It can only reach a high temperature and not a low temperature. The energy utilization is not reasonable. In addition, the internal and external leakage of valves and steam traps may cause high energy consumption.

[0006] The coal in the traditional ash hopper is of low quality. The ash powder after combustion will cause agglomeration due to low temperature, humidity and other reasons, resulting in poor ash discharge and possible safety accidents.

[0007] Therefore, we propose an anti-blocking and heat-free device for the dust collector hopper to solve the above-mentioned problems. Summary of the invention

[0008] The object of the present invention is to provide an anti-blocking and heat-free device for a dust collector ash hopper. By using the principle that like charges repel each other, an anti-blocking device is installed on the fluidized air duct, and the negative ion charge generated by the generator is brought into the ash hopper by the fluidized air, thereby increasing the dust charge in the ash hopper, thereby increasing the repulsive force between the negatively charged dust. Without the need for heating the ash hopper, the fly ash in the ash hopper is kept in a good fluidized and dispersed state, so as to solve the problem that the quality of the coal in the traditional ash hopper is low, and the ash powder after combustion will cause agglomeration due to low temperature, humidity and other reasons, resulting in poor ash discharge and possible safety accidents.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. The coal ash is put into the inner cylinder from the feed pipe. The impact force generated by the coal ash is applied to the first connecting fin and the second connecting fin, and drives the first connecting fin and the second connecting fin to rotate, which can not only stir the temperature inside the device, but also break up the coal ash and increase the possibility of fluidization. The outer cylinder is equipped with circulating water. The heating rod is turned on to continuously heat the inner cylinder inside and outside evenly. The circulating water is heated by the heating rod, which can play a role in uniform temperature for the ash hopper. The hot water will not cool down in a short time. With the action of the outer cylinder, it can keep the ash hopper warm and reduce the agglomeration of coal ash due to low temperature.

[0020] 2. After being heated by the heating rod, the hot water will boil and generate steam. The steam will be sprayed into the inner cylinder through the steam holes and the steam nozzles, and will also be sprayed onto the second connecting fins. While heating the coal ash, it will further drive the rotation of the first connecting fins and the second connecting fins, which is energy-saving and eliminates the possibility of coal ash agglomeration to a great extent.

[0021] 3. The inner wall of the inner cylinder is coated with a nano coating, which is an important component of the ash hopper anti-blocking system. The core of the coating has high insulation properties, which prevents charged fly ash from discharging to the ground. Later, the fly ash cannot adhere to the ash hopper wall in large quantities due to the mutual repulsion of like charges, so the fly ash is effectively dispersed. The nano material makes the contact surface between the fly ash and the ash hopper smoother and the ash flow smoother. Its unique wear-resistant and corrosion-resistant properties can better protect the ash hopper.

[0022] 4. During the rotation of the rotating ring, the turbine body rotates in the turbine casing, and the water in the water inlet pipe can be introduced into the guide pipe and the outer cylinder, forming a continuous water transport, which is convenient for water recycling. When the coal ash treatment is completed, the remaining temperature of the heating rod is heated again by hot water, and waste heat can be recovered, which reduces energy consumption and is convenient for use.

[0023] 5. After the ash treatment is completed, the sliding ring moves downward and sinks into the water, driving the water level to rise and exceed the highest water level of the siphon, thereby sucking all the hot water in the chamber into the storage tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figure 1-Figure 6 A device for preventing blockage and avoiding heating of a dust collector ash hopper comprises an ash hopper mechanism 1 and a feeding mechanism 2 arranged on one side of the ash hopper mechanism 1. The ash hopper mechanism 1 comprises an outer cylinder 11 and an inner cylinder 12 arranged on the inner wall of the outer cylinder 11. An upper cylinder 13 is installed on the upper ends of the outer cylinder 11 and the inner cylinder 12. The outer cylinder 11 and the inner cylinder 12 are combined to form an outer shell of the dust collector ash hopper, so that the ash hopper forms a double-layer structure, which is convenient for heat preservation and noise reduction.

[0028] The feeding mechanism 2 includes a feeding pipe 21 connected to the inner cylinder 12 and an anti-blocking device 22 arranged on the feeding pipe 21. The fly ash is put into the inner cylinder 12 through the feeding pipe 21 to continuously feed the device. The anti-blocking device 22 is a negative charge generator. The anti-blocking device 22 is the core of the dust collector hopper anti-blocking system. The fluidizing air is processed by using the patented product MAXON-F high-frequency, high-voltage, high-energy negative ion beam generator to add negative ion charge to the fly ash. The amount of electricity of the negatively charged fly ash entering the ash hopper is different. Although there is repulsion between the fly ashes, the repulsion between the high specific resistivity fly ash and the low specific resistivity fly ash is different. By adding negative ion charge to the fluidizing air, the fly ash collides with the negative ions and becomes negatively charged, which increases the repulsion between the fly ashes and prevents them from sticking together.

[0029] A heating mechanism 3 is provided inside the ash hopper mechanism 1. The heating mechanism 3 includes an upper mounting member 31 fixedly mounted on the upper end of the outer wall of the inner cylinder 12 and a plurality of heating rods 32 fixedly mounted on the lower end of the upper mounting member 31. A lower mounting member 33 is commonly mounted on the lower ends of the plurality of heating rods 32. The lower mounting member 33 is arranged at the lower end of the outer wall of the inner cylinder 12. Under the joint action of the upper mounting member 31 and the lower mounting member 33, the plurality of heating rods 32 are equidistantly arranged on the outer wall of the inner cylinder 12. The heating rods 32 are a type of electric heating, with a simple system, uniform heating, accurate temperature, quick response, remote control or remote control, and automatic management, low temperature state, fast start-up, and uniform temperature. Each part can be automatically adjusted due to the temperature change of the heated part. After it is turned on, the inner cylinder 12 can be heated to reduce the occurrence of agglomeration of fly ash due to low temperature, and the fly ash in the ash hopper is kept in a good fluidized and dispersed state.

[0030] An anti-caking mechanism 4 is provided inside the ash hopper mechanism 1. The anti-caking mechanism 4 includes a plurality of first connecting fins 45 rotatably mounted on the inner wall of the inner cylinder 12. A second connecting fin 46 is fixedly mounted on one end of the first connecting fin 45. The first connecting fin 45 and the second connecting fin 46 are arranged obliquely.

[0031] The coal ash is fed into the inner cylinder 12 from the feed pipe 21, and the second connecting fin 46 is inclined at a position where the coal ash is fed. Therefore, the impact force generated by the coal ash is applied to the first connecting fin 45 and the second connecting fin 46, and drives the first connecting fin 45 and the second connecting fin 46 to rotate, which can not only stir the temperature inside the device, but also break up the coal ash, increase the possibility of fluidization, and also has a certain energy-saving effect.

[0032] The inclination angle of the first connecting fin 45 is consistent with the inclination angle of the inner cylinder 12. The two are adapted but not fitted, which is convenient for reducing the friction between the first connecting fin 45 and the inner cylinder 12. It can not only reduce wear, but also increase the flexibility and smoothness of the rotation of the first connecting fin 45 and the second connecting fin 46.

[0033] There is a closed chamber between the outer cylinder 11, the inner cylinder 12 and the upper cylinder 13, which contains circulating water. Coal ash is continuously fed into the inner cylinder 12 through the feed pipe 21. The heating rod 32 is turned on to continuously and evenly heat the inside and outside of the inner cylinder 12. The circulating water is heated by the heating rod 32, which can achieve a uniform temperature for the ash hopper. The hot water will not cool down in a short time. Together with the outer cylinder 11, it can keep the ash hopper warm and reduce the agglomeration of coal ash due to low temperature.

[0034] Example 2: Please refer to Figure 2-Figure 6A lower cylinder 14 is installed together at the lower ends of the outer cylinder 11 and the inner cylinder 12, a sliding hole 15 is opened on the inner wall of the lower cylinder 14, a steam through hole 16 is opened on the inner wall of the upper end of the upper cylinder 13, a steam nozzle 17 is installed on the steam through hole 16, and the position of the steam nozzle 17 is adapted to the second connecting fin 46.

[0035] Hot water is provided in a sealed chamber common among the outer cylinder 11, the inner cylinder 12 and the upper cylinder 13. The hot water will boil and generate steam after being heated by the heating rod 32. The steam is sprayed into the inner cylinder 12 through the steam through hole 16 and the steam nozzle 17, and is also sprayed onto the second connecting fin 46. While heating the coal ash, it further drives the rotation of the first connecting fin 45 and the second connecting fin 46, which is energy-saving and eliminates the possibility of coal ash agglomeration to a great extent.

[0036] A limit ring 18 is fixedly installed on the inner wall of the lower end of the upper cylinder 13, and a buffer mechanism 8 is arranged inside the ash hopper mechanism 1. The buffer mechanism 8 includes an elastic member 81 fixedly installed on the top wall of the upper cylinder 13. The elastic member 81 is a structure with any elastic structure such as a spring and a bellows. A sliding ring body 82 is fixedly installed on the lower end of the elastic member 81. Under the action of the elastic member 81, the sliding ring body 82 is slidably installed in the upper cylinder 13. In the initial state, the sliding ring body 82 is located at the lower end of the steam through hole 16. In order to ensure that the circulating water does not come into contact with the external cold air before heating, the boiling efficiency of the hot water is improved.

[0037] When the circulating water boils, the steam pushes up, compresses the elastic member 81, and drives the sliding ring 82 to move upward until the steam through hole 16 is exposed, so that the steam heat is applied to the inner cylinder 12, thereby driving the first connecting fin 45 and the second connecting fin 46 to rotate, thereby heating the coal ash.

[0038] A charge detection sensor 19 is also embedded on the inner wall of the inner cylinder 12. The model of the charge detection sensor 19 is CA-YD-10. In order to determine the fluidization state of the fly ash in the ash hopper, the system measures the charge carrying amount of the fly ash in the ash hopper through the charge detection sensor 19. The detection sensor analyzes, guides and controls the output size of the negative ion generator, adjusts the working state of the anti-blocking device 22, and prevents insufficient fluidization of the dust in the ash hopper or excessive charge. The inner wall of the inner cylinder 12 is coated with a nano coating 9. The nano coating 9 is an important component of the ash hopper anti-blocking system. The core of the coating has high insulation properties, so that the charged fly ash cannot discharge to the ground. The subsequent fly ash cannot be adhered to the ash hopper wall in large quantities due to the mutual repulsion of like charges, so the fly ash is effectively dispersed. The nano material makes the contact surface between the fly ash and the ash hopper smoother and the ash flow smoother. Its unique wear resistance and corrosion resistance can better protect the ash hopper.

[0039] Example 3: Please refer to Figure 3-Figure 8 The anti-caking mechanism 4 also includes a rotating ring body 41 rotatably mounted in the lower cylinder 14 and an embedded groove 42 fixedly mounted on the upper end of the rotating ring body 41 , and the lower mounting member 33 is rotatably mounted in the embedded groove 42 .

The lower end of the first connecting fin 45 is fixedly connected to the inner wall of the connecting ring body 43. Under the action of the connecting ring body 43, multiple first connecting fins 45 and second connecting fins 46 are connected into a whole. During the rotation of the first connecting fins 45 and the second connecting fins 46, the connecting ring body 43 and the rotating ring body 41 rotate, having a certain degree of integrity.

[0041] A recovery mechanism 5 is provided on one side of the ash hopper mechanism 1. The recovery mechanism 5 includes a recovery pipe 51 connected to the upper cylinder 13. A storage tank 52 is fixedly installed at the lower end of the recovery pipe 51. If too much water is injected, the excess hot water will be poured into the storage tank 52 through the recovery pipe 51, which is convenient for hot water recovery. The height of the recovery pipe 51 is located at the lower end of the steam nozzle 17 to prevent excessive water from flowing into the inner cylinder 12, which can play an overflow role.

[0042] A water supply mechanism 6 is provided on one side of the ash hopper mechanism 1. The water supply mechanism 6 includes a fixed pipe 61 connected and installed on one side of the lower cylinder 14. A turbine housing 62 is fixedly installed on one end of the fixed pipe 61. A water inlet pipe 63 is connected and installed on the lower end of the turbine housing 62. A guide pipe 64 is fixedly installed on the upper end of the turbine housing 62. A one-way valve 65 is installed on the guide pipe 64. Cold water enters the chamber where the outer cylinder 11 and the inner cylinder 12 coexist through the water inlet pipe 63, the turbine housing 62 and the guide pipe 64 in sequence. The one-way valve 65 only allows water to enter but not exit, and water will not flow back from the guide pipe 64, which has a certain degree of protection.

[0043] A turbine mechanism 7 is provided on one side of the water supply mechanism 6, and the turbine mechanism 7 includes a second bevel gear 71 meshingly mounted on the upper end of the first bevel gear 44, a fixing rod 72 is fixedly mounted in the middle of the second bevel gear 71, and the fixing rod 72 is rotatably mounted inside the fixing tube 61, and a turbine body 73 is fixedly mounted on the outer periphery of the fixing rod 72, and the turbine body 73 is rotatably mounted inside the turbine housing 62.

[0044] A first bevel gear 44 is fixedly installed on the outer periphery of the lower end of the rotating ring body 41. During the rotation of the rotating ring body 41, the first bevel gear 44 rotates synchronously, and the second bevel gear 71 is meshed and connected with the first bevel gear 44, that is, the second bevel gear 71, the fixing rod 72, and the turbine body 73 rotate. The turbine body 73 rotates in the turbine casing 62, and the water in the water inlet pipe 63 can be introduced into the guide pipe 64 and the outer cylinder 11, so as to form a continuous water transportation and facilitate the recycling of water.

[0045] After the ash treatment is completed, the heating rod 32 is turned off, the rotating ring body 41 stops rotating, and the remaining temperature of the heating rod 32 is used to heat the hot water again, so that the waste heat can be recovered, which reduces energy consumption and is easy to put into use.

[0046] A siphon tube 53 is commonly provided inside the recovery tube 51 and the storage tank 52. A hole is provided on the sliding ring body 82 for interlacing and connecting with the siphon tube 53. The bottom of the siphon tube 53 is located in the lower cylinder body 14. Under the action of the recovery tube 51, the water inside the outer cylinder body 11 is always full and does not exceed the highest water level of the siphon tube 53. After the coal ash treatment is completed, the sliding ring body 82 moves downward and sinks into the water, driving the water level to rise and exceed the highest water level of the siphon tube 53, so that all the hot water in the chamber can be sucked into the storage tank 52 for easy recycling.
