Abstract
Description
Technical Field
[0001] The invention relates to the field of solid waste incineration treatment, and in particular to a fly ash separation system for industrial solid waste incineration treatment. Background Art
[0002] Fly ash produced by the incineration of industrial solid waste is a highly hazardous solid waste because it contains organic pollutants such as dioxins, benzopyrene, and benzanthracene, as well as heavy metals such as Cr, Cd, Hg, Pb, Cu, and Ni. Therefore, strict treatment measures must be taken.
[0003] The separation of fly ash from flue gas produced by the incineration of industrial solid waste is a multi-stage fine processing process. First, after the high-temperature flue gas is recovered through the boiler heat energy, it enters the quenching tower and uses water atomization to rapidly cool down to about 200°C, effectively curbing the regeneration of dioxins. Then, the flue gas reacts with slaked lime in the dry reaction tower to remove acidic gases such as SO2 and HCI, and activated carbon is sprayed to adsorb the remaining dioxins and heavy metals. After that, the flue gas enters the bag filter and separates the fine fly ash particles with the help of bag filtration. For further purification, the flue gas needs to be washed with sodium hydroxide solution to neutralize and absorb the residual acidic gas to ensure that it meets the emission standards. Finally, the purified flue gas is sent to the chimney by the induced draft fan for discharge. At the same time, the flue gas collected from the bag filter is The fly ash from the dust collector will undergo subsequent treatment measures such as cement solidification, chemical stabilization or high-temperature melting to ensure its harmless disposal and protect the environment and public health. The whole process systematically realizes the cooling of flue gas, removal of pollutants, capture of fly ash and environmental protection treatment, reflecting the strict control of industrial waste management and the high attention paid to environmental protection. In the dust removal step, there is an obvious jet phenomenon at the inlet of the existing bag dust collector, which will cause uneven airflow in the dust collector. During long-term operation, the same side of the dust bag is long-term flushed by dust gas, and the dust bag on the side away from the air inlet cannot efficiently participate in the filtration of dust gas. Due to insufficient fluid diffusion, efficient and uniform filtration of dust gas cannot be achieved, reducing the dust removal efficiency.
[0004] The currently disclosed Chinese patent CN210786572U discloses a device for efficiently removing dust and dioxins from waste incineration flue gas, including a compressed air tank, a blow pipe, a solenoid valve, a sealing plate, a box body, and a compressed air tank, a blow pipe, a solenoid valve, a sealing plate, and a box body. It is characterized in that two bag dust collectors are connected in series in the form of a primary and a secondary stage, guide plates are arranged behind the flue gas inlet channels of the primary and secondary bag dust collectors, and an activated carbon injection device is arranged at the outlet of the primary bag dust collector.
[0005] According to the above patent, a guide plate is arranged behind the flue gas inlet to make the airflow distribution in the bag filter more uniform, improve the dust removal efficiency, reduce the scouring of the filter bags by the jet, and extend the service life of the bags. However, it may be difficult to achieve all-round and uniform distribution of dust-containing gas on the bag surface by relying solely on a single guide plate design. Although the guide plate can effectively improve the local airflow distribution, reduce the jet phenomenon, and guide part of the airflow to the bag away from the air inlet side, it may not be enough to ensure that all bag surfaces can be fully and evenly covered by the dust-containing gas. Therefore, there is a need for a guide structure that can fully apply the dust-containing gas to the bag filter. Summary of the invention

DETAILED DESCRIPTION
[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0030] See also Figure 1-Figure 8As shown, the fly ash separation system for incineration of industrial solid waste includes a flue gas cooling and preliminary treatment unit, an acid gas and heavy metal removal unit, a dust removal treatment unit, a flue gas cleaning and emission unit and a fly ash collection and treatment unit. The dust removal treatment unit includes a dust removal box 1, and bag dust collectors 2 arranged in a matrix in the dust removal box 1. The dust removal box 1 has a partition 3 that divides its interior into a lower cavity 31 for flue gas to enter and an upper cavity 32 for clean gas to discharge. The needle on the partition 3 Each bag-type dust collector 2 is provided with a guide tube 4 in which it is sleeved, and a movable frame 5 for fixing the bag-type dust collector 2 is slidably provided in the guide tube 4. The dust removal box 1 is also provided with a vibration component 6 for driving all the movable frames 5 to move synchronously. When the movable frames 5 vibrate in the guide tube 4 through the vibration component 6, the flue gas entering the guide tube 4 is disturbed by the movable frame 5, so that the flue gas is evenly distributed on the surface of the bag-type dust collector 2, and the dust attached to the bag-type dust collector 2 is shaken off.
[0031] The dust collecting box 1 is provided with an air inlet 11 at a position below the bag-type dust collector 2, and an air outlet 12 is provided at a position above the bag-type dust collector 2. A dust outlet 13 is provided at the bottom of the dust collecting box 1. During the flue gas treatment process, the flue gas that has been cooled and preliminarily treated, carrying incompletely burned particulate matter and harmful substances, first enters the lower cavity 31 through the air inlet 11 of the dust collecting box 1. Since each bag-type dust collector 2 is provided with a guide tube 4, the flue gas enters it through the guidance of the guide tube 4, and each surface of the bag-type dust collector 2 can receive an equal or similar flue gas flow, ensuring the high efficiency and balance of the filtering process, avoiding premature blockage or wear of the local bag-type dust collector 2, and filtering through the bag-type dust collector 2 therein During the flue gas filtering process, the movable frame 5 moves through the vibration component 6, which not only causes the incoming flue gas to be disturbed inside the guide tube 4 and evenly distributed on the surface of the bag-type dust collector 2, that is, the vibration of the movable frame 5 effectively breaks up the flue gas flow that originally concentrated on a certain area, causing it to disperse and cover the surface of the bag-type dust collector 2, rather than being limited to one side of the bag-type dust collector 2. At the same time, the dust attached to the surface of the bag-type dust collector 2 is separated from the surface of the bag-type dust collector 2 due to the combined action of inertia and friction. The clean gas filtered by the bag-type dust collector 2 is discharged from the air outlet 12 of the upper cavity 32, and the trapped dust falls to the bottom of the dust removal box 1 under the action of gravity, and is finally collected through the dust outlet 13, preparing for the subsequent fly ash collection and treatment.
[0032] See also Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig.10As shown, the upper end of the movable frame 5 is movably connected to the partition 3, and the lower end of the movable frame 5 is fixedly connected to the vibration assembly 6. The movable frame 5 has a spoiler 51 for breaking up the concentrated smoke during its vibration.
[0033] The movable frame 5 is evenly distributed with a plurality of spoilers 51 along the axial direction of the bag-type dust collector 2. When the vibration assembly 6 is started, the vibration wave is transmitted to the bag-type dust collector 2 through the movable frame 5, so that the dust on the bag-type dust collector 2 falls off. At the same time, the spoiler 51 follows the movement of the movable frame 5 to effectively break up the flue gas that may have originally flowed in a concentrated manner, and prompts the flue gas to form a more uniform airflow distribution before entering the bag-type dust collector 2, and is evenly distributed on the surface of the bag-type dust collector 2. This process not only optimizes the distribution of the airflow, but also promotes full contact between the flue gas and the surface of the bag-type dust collector 2, thereby improving the filtration efficiency, while reducing the impact on the local area of the bag-type dust collector 2 and extending the service life of the bag-type dust collector 2.
[0034] See also Fig.10 As shown, the spoiler 51 is an annular structure surrounding the movable frame 5 , and a spoiler groove 511 is provided on the outer edge of the spoiler 51 to further achieve a flow diversion effect.
[0035] The outer edge of the spoiler 51 is evenly provided with a plurality of spoiler grooves 511 along its circumferential direction. When the movable frame 5 vibrates under the drive of the vibration component 6, the annular spoiler 51 and the spoiler grooves 511 provided on its edge cooperate with each other. The vibration of the spoiler 51 itself can effectively break up the smoke flow, and the additional spoiler grooves 511 further refine the dispersion of the airflow by locally changing the airflow path, so that the airflow is more evenly dispersed to the surface of the bag-type dust collector 2. Through the guidance of the spoiler grooves 511, the high-speed airflow that may have been formed is divided into a plurality of small airflows, thereby reducing the direct impact force of the airflow on the bag-type dust collector 2 and avoiding excessive local pressure and wear. At the same time, it also ensures that the contact between the smoke and the surface of the bag-type dust collector 2 is more even, thereby improving the overall filtering efficiency and purification effect.
[0036] See also Figure 7 and Figure 8 As shown, a gap is left between the movable frame 5 and the bag filter 2 for smoke to flow.
[0037] The existence of the gap ensures that the flue gas can be evenly distributed before passing through the bag collector 2, avoiding the situation where a local area of the bag collector 2 is blocked by the movable frame 5 and the area cannot have a filtering effect, which helps to evenly distribute the flue gas on the surface of the bag collector 2, thereby improving the overall filtering efficiency.
[0038] See also Figure 2 and Figure 3As shown, a support step 311 fixedly connected to the lower ends of all guide tubes 4 is provided in the lower cavity 31 of the dust removal box 1, and a drainage channel 312 for smoke to pass directly into the guide tube 4 from bottom to top is opened on the support step 311 corresponding to each guide tube 4.
[0039] The drainage channel 312 follows the direction from bottom to top and is directly connected to the lower end of each guide tube 4, forming a smooth airflow path. When the smoke enters through the lower cavity 31, it is guided in an orderly manner and directly transported to the corresponding guide tube 4 through these drainage channels 312, thereby achieving precise control of the smoke flow direction, avoiding disordered diffusion of the airflow before entering the guide tube 4, and entering the filtering area of the bag filter 2 more directly and quickly, reducing the residence time of the smoke before entering, helping to improve the smoke capture efficiency, thereby improving the purification efficiency of the entire dust removal treatment unit.
[0040] See also Figure 2 and Figure 3 As shown, the drainage channel 312 is specifically an upper flared structure whose upper half is connected to the guide tube 4, and a lower flared structure whose lower half is connected to the upper flared structure. The upper flared structure and the connected lower flared structure are used to ensure that the smoke is evenly dispersed into the guide tube 4 in a smooth state.
[0041] When the flue gas flows upward from the lower cavity 31, it first passes through the lower expansion structure, which is designed to initially receive and begin to guide the flue gas. Then, the flue gas continues to rise and enters the upper expansion structure, and a gradually expanding channel is formed between the structure and the guide tube 4. The continuous transition between the upper expansion and the lower expansion allows the flue gas to experience a change in flow channel from narrow to wide before entering the guide tube 4, which slows down the flue gas flow rate and evenly disperses it throughout the guide tube 4 instead of concentrating it in a certain part, ensuring the uniform distribution of the flue gas when it enters the dust removal area, eliminating the local high-speed phenomenon of the airflow, and smoothly guiding the flue gas into the guide tube 4, avoiding the direct impact of the local high-speed airflow on the bag collector 2, thereby increasing the service life of the bag collector 2.
[0042] See also Figure 2 , Figure 3 and Figure 7-Figure 9 As shown, the upper end of the movable frame 5 has a vibration ring 41 movably connected to the partition 3, and the partition 3 is provided with a movable opening along the axial direction of the guide tube 4 for the vibration ring 41 to be slidably set therein, and the inner wall of the guide tube 4 has a fixed step 42 located below the vibration ring 41 around it, and a vibration spring 43 is fixedly connected between the vibration ring 41 and the fixed step 42 for a reset effect.
[0043] When the vibration ring 41 moves with the movable frame 5 under the drive, the vibration spring 43 can provide the necessary elastic restoring force. The driver 61 cooperates with the vibration spring 43 to ensure that the movable frame 5 achieves a continuous vibration effect. The vibration of the movable frame 5 drives the vibration ring 41 to move up and down, so that the vibration ring 41 impacts the partition 3. This moment generates a vibration force on the dust on the surface of the bag-type dust collector 2, which effectively promotes the shedding of accumulated dust, improves the cleaning efficiency, reduces the possibility of clogging of the bag-type dust collector 2, and extends the service life of the bag-type dust collector 2.
[0044] See also Figure 2 , Figure 3 and Fig. 9 As shown, a buffer washer 411 is provided between the partition plate 3 and the vibration ring 41 to prevent the vibration ring 41 from directly hitting the partition plate 3 .
[0045] The buffer washer 411, as a component made of elastic or shock-absorbing material, can effectively absorb the impact force of the vibration ring 41 on the partition 3 during the up and down movement, prevent direct impact, thereby reducing damage to the partition 3 and the vibration ring 41, and extending the service life. In addition, through the buffering effect of the buffer washer 411, the transmission of vibration energy is smoother and more effective, avoiding energy loss caused by direct impact, making the cleaning of the surface of the bag collector 2 more uniform and efficient, and further improving the cleaning effect.
[0046] See also Figure 2 and Figure 3 As shown, the vibration assembly 6 includes a driver 61 for providing a vibration effect, and a connector 62 connected between the driver 61 and all movable frames 5 for transmitting vibration force.
[0047] When the driver 61 starts working and generates vibration energy, the connecting member 62 acts as a bridge between the driver 61 and all the movable frames 5, and efficiently and evenly transmits the vibration energy generated by the driver 61 to each movable frame 5. After receiving the vibration energy, the movable frame 5 begins to vibrate up and down regularly according to the frequency and amplitude set by the driver 61, and finally acts on the surface of the bag-type dust collector 2, causing the accumulated dust to fall off due to the vibration force. At the same time, the vibration can also improve the airflow distribution around the bag-type dust collector 2 through the spoiler 51, avoid local airflow stagnation or excessive concentration, and further optimize the filtering and dust removal effects.
[0048] See also Figure 2-Figure 5As shown, the connecting member 62 has a hole plate 621 connected to the driver 61, and a shaft rod 622 fixedly connected between the hole plate 621 and all the movable frames 5. When the hole plate 621 moves downward under the drive of the driver 61, the vibration spring 43 is in a state of being compressed downward, and when the driver 61 releases the driving state of the hole plate 621, the vibration spring 43 is in a state of recovering upward without being affected by external force, so that the movable frame 5 moves up and down.
[0049] The orifice plate 621 can allow smoke to pass through, and the shaft rod 622 passes through the corresponding drainage channel 312. The driver 61 has a fixed magnet 611 fixedly connected to the dust removal box 1, and has an active magnet 612 fixedly connected to the orifice plate 621. The matching fixed magnet 611 and active magnet 612 are evenly distributed around the orifice plate 621. The fixed magnet 611 and the active magnet 612 are both electromagnets. When the fixed magnet 611 and the active magnet 612 are both energized, the fixed magnet 611 repels the active magnet 612, so that the orifice plate 621 moves downward, thereby driving all the active frames 5 to move downward through the shaft rod 622. At this time, the vibration spring 43 is in a compressed state, and as the orifice plate 621 moves down to the specified position, the fixed magnet 611 and the active magnet 612 are simultaneously powered off, and under the action of the vibration spring 43, the active frame 5 is driven to move upward and return to its original position. During this process, the vibration ring 41 impacts the partition 3 through the buffer gasket 411, and the movable frame 5 is subjected to the vibration force, which effectively realizes the vibration and removal of dust on the surface of the bag-type dust collector 2, and also enables the spoiler 51 to disperse the smoke in the guide tube 4 during the movement of the movable frame 5, thereby avoiding the concentration of smoke. The driver 61 and the vibration spring 43 cooperate to continuously and reciprocately drive the movable frame 5 up and down, so that the smoke is evenly dispersed on the surface of the bag-type dust collector 2, and the effective filtering performance of the bag-type dust collector 2 is maintained for a long time.
[0050] The present invention uses precise airflow control and a vibration cleaning mechanism to evenly disperse the flue gas on the surface of the bag-type dust collector 2, thereby preventing the flue gas that locally concentrates on one side of the bag-type dust collector 2 from causing excessive impact on the bag-type dust collector 2, ensuring that particulate matter in the flue gas is removed to the maximum extent. At the same time, during the vibration of the bag-type dust collector 2, the dust on its surface is continuously shaken off, thereby maintaining the efficient and long-term filtering performance of the bag-type dust collector 2, improving the dust removal effect, and avoiding the jet phenomenon.
[0051] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
