Abstract
Description
Technical Field
[0001] This utility model relates to the field of desulfurization treatment technology, and in particular to a desulfurization waste ash recovery device. Background Technology
[0002] A desulfurization system is a system that removes sulfur-containing compounds (mainly sulfur dioxide SO2 and hydrogen sulfide H2S) from fuels (such as coal, oil, and natural gas), industrial raw materials, or flue gas. Its purpose is to reduce sulfur oxide emissions, prevent equipment corrosion, and meet environmental regulations. During the desulfurization process, solid waste ash is generated. To prevent secondary pollution risks from solid waste ash emissions, and because the solid waste ash contains unreacted desulfurizing agents, it needs to be recycled. In existing technologies, the recycling of desulfurization waste ash mainly relies on installing a dust collection box at the bottom of the desulfurization tower. By opening the ash discharge hole at the bottom of the desulfurization tower, the waste ash falls and is collected into the dust collection box by gravity settling. While this method effectively collects solid waste ash, it still has some technical defects and operational problems, mainly including the following aspects:
[0003] (1) Failure of powder fluidization: High-calcium-based waste ash (CaSO3 content > 60%) forms dense arched agglomerates (compressive strength > 10 kPa) in the dust collection box, which are difficult to remove by vibration using a rapping device, thus increasing the difficulty of waste ash recycling; (2) Escape of fine particles: Waste ash particles with a diameter < 10 μm are prone to aerosol diffusion (PM2.5) during the open environment ash collection process. 2.5 Instantaneous concentration can reach 80 mg / m³ 3 This exceeds the limit specified in GB16297-1996 standard.
[0004] It should be noted that the above content is only used to help understand the technical solution of this utility model, and does not represent an admission that the above content is prior art. Utility Model Content

[0033] In existing technologies, the recycling and treatment of desulfurization waste ash mainly relies on setting up a dust collection box at the bottom of the desulfurization tower. By opening the waste discharge hole at the bottom of the desulfurization tower, the waste ash is collected into the dust collection box below by gravity settling. Although the above method can effectively concentrate solid waste ash, there are still some technical defects and operational problems, mainly including the following aspects: (1) Failure of powder fluidization: High calcium-based waste ash (CaSO3 content >60%) forms dense arch bridge agglomerates (compressive strength >10kPa) in the dust collection box, which is difficult to remove by vibration with a rapping device, thus increasing the difficulty of waste ash recycling; (2) Escape of fine particles: Waste ash particles with a particle size <10μm are prone to aerosol diffusion (PM) during the falling and recycling process. 2.5 Instantaneous concentration can reach 80 mg / m³ 3 This exceeds the limit specified in GB16297-1996 standard.
[0034] To solve the above-mentioned technical problems, this utility model proposes a desulfurization waste ash recovery device.
[0035] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the desulfurization waste ash recovery device is applied to a desulfurization treatment system, wherein the desulfurization treatment system includes a desulfurization tower 1;
[0036] Specifically, the desulfurization waste ash recovery device includes:
[0037] Ash storage silo 2, with an ash inlet 201 at the upper end and a first valve 3 at the ash inlet 201, the ash inlet 201 is connected to the ash discharge hole 101 at the bottom of the desulfurization tower 1; and an ash outlet 202 at the lower end of the ash storage silo 2, with a second valve 4 at the ash outlet 202.
[0038] Fluidization component 5 is used to inject a first airflow into the ash storage bin 2. The first airflow is used to drive the waste ash to move so that the waste ash remains fluidized.
[0039] The ash bin 6 and the pipe assembly 7 are connected to the ash outlet 202 through the pipe assembly 7. The ash bin 6 is used for the unified recycling of waste ash.
[0040] The technical solution of this utility model directly connects the ash inlet 201 of the ash storage bin 2 to the ash discharge hole 101 of the desulfurization tower 1, using the ash storage bin 2 as a transfer station for waste ash. When the waste ash in the ash storage bin 2 reaches a preset amount, the second valve 4 is opened to allow the waste ash to fall from the ash outlet 202 of the ash storage bin 2 under its own weight and be transported along the pipeline assembly 7 to the waste ash bin 6 for unified recycling. A first airflow is injected into the ash storage bin 2 using the fluidizing component 5. This first airflow is used to move the waste ash to keep it fluidized and prevent the formation of dense arch bridges and agglomerates. Simultaneously, the first valve 3, the second valve 4, and the pipeline assembly 7 form a fully enclosed conveying path, eliminating the aerosol diffusion phenomenon caused by traditional open ash dropping methods and preventing the escape of fine particles from the waste ash, which could lead to environmental pollution. Furthermore, the fully enclosed conveying path also prevents external moisture from combining with the waste ash, achieving a waste ash moisture content control of <0.5%; it also prevents the waste ash (especially when containing carbon or sulfides) from coming into contact with external oxygen and causing a risk of combustion and explosion. In addition, the above process can be operated in a fully automated manner, which can significantly reduce labor and maintenance costs and reduce human intervention: it can save more than 50% of labor costs and optimize energy consumption.
[0041] Among them, the inner lining of the ash storage silo 2 is provided with an alumina wear-resistant ceramic layer with a thickness of 2-4mm (Rockwell hardness ≥85HRA), ensuring wear resistance life ≥10 years.
[0042] Specifically, the first valve 3 is configured as a flap valve; thus, the flap valve, also known as a gravity airlock valve, opens when the waste ash in the desulfurization tower 1 accumulates to a preset weight, allowing the waste ash to fall from the desulfurization tower 1 into the ash storage bin 2 under its own weight, thereby automating the ash removal operation of the desulfurization tower 1. It should be noted that in actual operation, operators can also manually open the flap valve according to the site conditions, thereby improving the flexibility of operating the first valve 3.
[0043] Specifically, the second valve 4 is configured as a rotary discharge valve. This configuration utilizes the rotary discharge valve (also known as a star-shaped discharger), a key piece of equipment widely used in industrial material conveying systems, primarily for the quantitative discharge and sealing of powdery and granular materials. In actual operation, operators can manually or automatically open the rotary discharge valve. Simultaneously, to increase the discharge speed of the ash storage silo 2, a pressurization component can be installed within the ash storage silo 2. This increases the air pressure inside the ash storage silo 2, and according to airflow principles, the high-pressure air carries the waste ash from the ash storage silo 2 to the pipeline assembly 7, further ensuring the smooth implementation of the technical solution of this application. In this embodiment, the rotary discharge valve uses a wear-resistant stainless steel rotor (gap ≤ 0.1 mm) and a variable frequency motor (adjustable from 0.5-5 r / min) to achieve controllable ash discharge (accuracy ±2%).
[0044] As a preferred embodiment of the above embodiments, refer to Figure 2 The bottom of the ash storage silo 2 is designed as a conical structure (cone angle ≥ 65°), and the fluidization component 5 is disposed in the conical part of the ash storage silo 2. Specifically, the fluidization component 5 includes an air source device 501 and a microporous fluidizing plate 502. The first airflow emitted by the air source device 501 is injected into the interior of the ash storage silo 2 through the microporous fluidizing plate 502. With this configuration, the microporous fluidizing plate 502 is installed in the conical part at the bottom of the ash storage silo 2, and its micropore diameter is Φ0.3-0.5mm with an opening rate ≥ 40%. The first airflow of 0.15~0.25MPa is introduced through the air source device 501. The first airflow passes through the micropores of the microporous fluidizing plate 502 to form a turbulent airflow, so as to drive the waste ash to float with the first airflow to form a fluidized state, thereby ensuring the smooth implementation of the technical solution of this application.
[0045] Meanwhile, the bottom of the ash storage bin 2 is designed as a conical structure (cone angle ≥ 65°), mainly to utilize the effect of the conical geometry to overcome the arch bridge effect. It is understandable that waste ash is prone to forming arch bridges in rectangular or shallow conical containers, while the design of a cone angle ≥ 65° makes the side wall inclination angle greater than the waste ash angle of repose, eliminating the mechanical equilibrium point of static particle accumulation and forcing the waste ash to slide down the conical slope. At the same time, the design of the gas source device 501 combined with the microporous fluidizing plate 502 forms a gas-solid lubrication layer, converting solid friction. Furthermore, the alumina ceramic lining of the ash storage bin 2 provides an ultra-smooth wall surface to maintain continuous flow, thereby achieving the rectification process of reducing the waste ash angle of repose. After testing, the waste ash angle of repose was reduced from 68° to 35°, achieving the purpose of avoiding the formation of dense arch bridge agglomerates.
[0046] As a preferred embodiment of the above embodiments, refer to Figure 2 An observation window 203 is provided on the side of the ash storage silo 2. The observation window 203 has an openable structure. This design allows operators to observe the accumulation of waste ash inside the ash storage silo 2. The openable structure of the observation window 203 allows operators to manually remove dense, arched clumps of ash using an external cleaning scraper when they are present in the ash storage silo 2. It also allows for periodic cleaning of the dust on the inner surface of the glass of the observation window 203 to ensure clear observation. The glass of the observation window 203 is made of tempered borosilicate glass (temperature resistance ≥300℃, impact strength ≥1.5J), and a fluororubber gasket (corrosion resistant) seals the glass and frame. The observation window 203 features a hinged flip-top design, with stainless steel hinges, a power spring, and a safety lock pin to achieve opening and closing.
[0047] As a preferred embodiment of the above embodiments, refer to Figure 2The ash storage silo 2 is externally equipped with a vibrating device 8. This vibrating device 8 (also known as a silo wall vibrator) continuously vibrates and strikes the ash storage silo 2, loosening the agglomerated powdery material through periodic mechanical vibration and restoring its flowability. In this embodiment, the vibrating device 8 works in conjunction with the fluidization component 5 to completely eliminate the risk of agglomeration. In this embodiment, the vibrating device 8 is a pneumatic vibrator with a frequency of 50Hz and an excitation force ≥5kN. Furthermore, two vibrating devices 8 are included, symmetrically arranged on the left and right sides of the ash storage silo 2; this improves the efficiency of the vibration and striking of the ash storage silo 2.
[0048] As a preferred embodiment of the above, the ash storage silo 2 is externally covered with an insulation layer (not shown in the attached drawings). This design ensures that the outer wall temperature of the silo is below 50°C, preventing water vapor condensation and the formation of dense arched bridges from the ash agglomeration. In this embodiment, the insulation layer is made of aluminum silicate material (thermal conductivity ≤0.05W / m·K). Furthermore, the insulation layer also indirectly improves the airtightness of the ash storage silo 2 (leakage rate <0.5%), effectively preventing the ash from leaking out and polluting the environment.
[0049] As a preferred embodiment of the above embodiments, refer to Figure 1 The pipeline assembly 7 includes a first ash conveying pipeline 701, a second ash conveying pipeline 702, and a main ash conveying pipeline 703. The first end of the first ash conveying pipeline 701 is connected to the ash outlet 202, and the first end of the second ash conveying pipeline 702 is connected to a dust collector 12, which is used to perform dust removal operations on the desulfurization tower 1. The first end of the main ash conveying pipeline 703 is simultaneously connected to the second ends of both the first ash conveying pipeline 701 and the second ash conveying pipeline 702, and the second end of the main ash conveying pipeline 703 is connected to the waste ash silo 6. Specifically, the first ash conveying pipeline 701 is equipped with a first fan 9, which is used to drive waste ash sequentially through the first ash conveying pipeline 701 and the main ash conveying pipeline 703 to the waste ash silo 6. The second ash conveying pipeline 702 is equipped with a second fan 10, which is used to drive the dust from the dust collector 12 sequentially through the second ash conveying pipeline 702 and the main ash conveying pipeline 703 to the waste ash silo 6. With this configuration, when waste ash falls into the first ash conveying pipe 701, it moves from the first end of the first ash conveying pipe 701 to its second end under the drive of the first fan 9; at the same time, the dust generated by the dust collector 12, as the existing dust removal equipment of the desulfurization tower 1, also moves from the first end of the second ash conveying pipe 702 to its second end under the drive of the second fan 10; at this time, the airflow of the first fan 9 and the second fan 10 merges at the first end of the main ash conveying pipe 703, and under the combined action of the airflow of the first fan 9 and the second fan 10, the waste ash and dust move along the main ash conveying pipe 703 towards the waste ash bin 6, and are finally stored in the waste ash bin 6; to ensure the smooth implementation of the technical solution of this application.
[0050] In this embodiment, the first fan 9 is configured as a fluidizing fan. This configuration utilizes the fluidizing fan, an industrial device based on fluid dynamics principles, primarily used to fluidize particulate materials (similar to a fluid state) through high-speed airflow. By using the fluidizing fan as one of the power sources to drive the waste ash along a specified direction, the waste ash is kept fluidized at all times, preventing agglomeration during movement.
[0051] In this embodiment, the second blower 10 is a Roots blower. This configuration ensures the smooth implementation of the technical solution presented in this application by using the Roots blower as a second power source to drive the waste ash in a designated direction. (Note: The original text contains some inconsistencies and inconsistencies in the original text. A more accurate translation would require the full context.)
[0052] Further, refer to Figure 1 and Figure 3 The first ash conveying pipe 701 has a first inclined section 7011 at its second end, and the first ash conveying pipe 701 is connected to the main ash conveying pipe 703 through the first inclined section 7011; and / or, the second ash conveying pipe 702 has a second inclined section 7021 at its second end, and the second ash conveying pipe 702 is connected to the main ash conveying pipe 703 through the second inclined section 7021. This arrangement ensures that when the airflow from the first fan 9 reaches this position, it flows smoothly along the first inclined section 7011 towards the main ash conveying pipe 703, preventing it from flowing towards the second ash conveying pipe 702 and causing convective interference between it and the airflow from the second fan 10. The reason for setting the second inclined section 7021 in the second ash conveying pipe 702 is similar, and therefore will not be described in detail here.
[0053] Further, refer to Figure 1 and Figure 3 The first ash conveying pipe 701 and / or the second ash conveying pipe 702 and / or the main ash conveying pipe 703 are equipped with pressure sensors 11 and backflushing components (not shown in the attached drawings). The pressure sensors 11 are electrically connected to the backflushing components. The pressure sensors 11 are used to detect the pipe pressure of their respective pipes. Specifically, the pressure sensors 11 are installed in the sections of the pipes where ash easily accumulates, such as those shown in the attached drawings. Figure 1At the junction of the first ash conveying pipe 701, the second ash conveying pipe 702, and the main ash conveying pipe 703, a backflushing assembly is used to send a second airflow in the opposite direction to the preset flow direction of the waste ash in the corresponding pipe. This configuration ensures that when waste ash accumulates and blocks in the first ash conveying pipe 701, the second ash conveying pipe 702, or the main ash conveying pipe 703, causing the pipe pressure detected by the pressure sensor 11 to be too high, the backflushing assembly is activated to blow the waste ash in the opposite direction, hoping to disperse the accumulated material and ensure smooth waste ash transport. The backflushing assembly uses a frequency converter to control the fan, and the gas pressure needs to be adjusted according to the pipe length and the degree of blockage; it includes a pulse jet assembly: a pulse valve (core component) with a response time of <50ms, capable of instantly releasing high-pressure gas.

Since this desulfurization treatment system adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here.
[0055] It should be noted that other aspects of the desulfurization waste ash recovery device disclosed in this utility model are existing technologies and will not be described in detail here.
[0056] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any application of this utility model directly or indirectly in other related technical fields is included within the patent protection scope of this utility model.
