Abstract
Description
Technical Field
[0001] This application relates to the field of dust removal equipment technology, and in particular to a device for eliminating water accumulation and preventing corrosion on the top of a centralized ash silo in a dust removal system. Background Technology
[0002] Centralized ash silos for environmental dust collection utilize efficient dust removal technologies, such as bag filters, to effectively capture and process dust particles within the silo, reducing dust emissions, improving environmental quality, and achieving resource recycling. However, the silo roof is horizontally positioned without any inclination, and other related dust collection equipment, including scraper conveyor tail wheels, silo top dust collectors, and cable trays, is often installed on the roof. This results in a situation where the roof is lower in the middle and higher around the edges, making drainage impossible. Prolonged water accumulation easily leads to corrosion and perforation of the roof's iron plate, causing water ingress into the ash silo and posing significant challenges to ash transport. Large amounts of water ingress necessitate silo cleaning, which is a labor-intensive process. Therefore, this application provides a water-accumulation and corrosion-preventing device for the top of a centralized ash silo in a dust collection system to address these problems. Utility Model Content
[0003] In order to eliminate water accumulation and prevent corrosion on the top of the centralized ash silo and ensure its service life, this application provides a water accumulation and corrosion prevention device for the top of the centralized ash silo in a dust removal system.
[0004] The technical solution provided in this application for a water-eliminating and corrosion-preventing device for the top of a centralized ash silo in a dust removal system is as follows:
[0005] A device for eliminating water accumulation and preventing corrosion on the top of a centralized ash silo in a dust removal system includes a centralized ash silo. The top wall of the centralized ash silo has an opening and a flow guiding system. The flow guiding system includes a rainwater collection hopper and a flow guiding pipe. The inner wall of the rainwater collection hopper is inclined towards the center. The diameters of the two ends of the rainwater collection hopper are φ120 and φ70, respectively. One end of the flow guiding pipe is connected to the rainwater collection hopper, and the other end extends out of the side wall of the centralized ash silo. The size of the flow guiding pipe is DN60.
[0006] By adopting the above technical solution, the water accumulated on the top of the centralized ash silo will flow towards the rainwater collection hopper and be discharged through the guide pipe, thereby preventing rainwater from accumulating on the top of the centralized ash silo, which would otherwise cause corrosion and damage, and prevent rainwater from entering the interior of the centralized ash silo and causing internal ash caking. This extends the service life of the centralized ash silo and ensures its normal operation.
[0007] Preferably, the flow guiding system further includes an impurity screen plate, which is disposed at the opening on the top wall of the centralized ash silo, and the rainwater collection hopper is located below the impurity screen plate.
[0008] By adopting the above technical solution, the impurity screen plate can isolate impurities such as leaves and garbage from the top of the centralized ash silo, so that staff can clean the impurities regularly, keep the guide pipe unobstructed, and reduce the probability of the guide pipe being blocked by impurities.
[0009] Preferably, the impurity sieve plate is honeycomb-shaped.
[0010] By adopting the above technical solution, the honeycomb-shaped impurity screen plate can effectively block impurities, preventing them from entering the rainwater collection hopper and causing blockage inside the diversion system, thus affecting the centralized ash silo from effectively draining water.
[0011] Preferably, the guide pipe is L-shaped, the vertical section of the guide pipe is connected to the rainwater collection hopper, and the angle between the vertical section and the horizontal section of the guide pipe is 93°.
[0012] By adopting the above technical solution, the diversion pipe is set in an L-shape, which can divert rainwater and facilitate the faster removal of water accumulated on the top of the centralized ash silo, reducing the probability of damage to the centralized ash silo.
[0013] Preferably, the surface of the guide tube is coated with a zinc protective layer.
[0014] By adopting the above technical solution, the zinc protective layer can play a role in corrosion protection for the guide pipe, thereby effectively extending the service life of the corrosion protection device of this application.
[0015] Preferably, one end of the guide pipe that passes through the wall of the centralized ash silo is welded and fixed to the connection point of the centralized ash silo.
[0016] By adopting the above technical solution, the stability of the diversion pipe can be maintained to prevent it from falling off during the drainage of accumulated water, thus ensuring the concentrated and stable discharge of rainwater.
[0017] Preferably, the opening size of the top wall of the centralized ash silo is φ120, and the diameter of the impurity screen plate is φ120.
[0018] By adopting the above technical solution, the opening size at the top of the centralized ash silo is consistent with the size of the impurity screen plate and the large-diameter end of the rainwater collection hopper, which can effectively ensure the smoothness and convenience of the installation of the diversion system of this application.
[0019] Preferably, the hole in the top wall of the centralized ash silo is located in a low-lying area of the top wall of the centralized ash silo.
[0020] By adopting the above technical solution, opening holes in the low-lying areas of the top wall of the centralized ash silo helps the water accumulated on the top wall of the centralized ash silo to flow towards the low-lying areas and enter the rainwater collection hopper. This can better solve the problem of rainwater deposition on the top of the centralized ash silo, and prevent rainwater from accumulating on the top of the centralized ash silo for a long time, causing corrosion and breakage, and preventing rainwater from entering the centralized ash silo, which would further lead to the dust collector ash getting damp and hardening at the bottom of the silo.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. The water accumulated on the top of the centralized ash silo will flow towards the rainwater collection hopper and be discharged through the guide pipe, thereby preventing rainwater from accumulating on the top of the centralized ash silo, which would lead to corrosion and damage to the centralized ash silo, and prevent rainwater from entering the interior of the centralized ash silo, causing the problem of ash caking. This extends the service life of the centralized ash silo and ensures its normal operation.
[0023] 2. The impurity screen plate can isolate impurities such as leaves and garbage from the top of the centralized ash silo, so that staff can clean the impurities regularly, keep the guide pipe unobstructed, and reduce the probability of the guide pipe being blocked by impurities.
[0024] 3. The honeycomb-shaped impurity screen plate can effectively block impurities, preventing them from entering the rainwater collection hopper and causing blockage inside the diversion system, thus affecting the centralized ash silo and preventing effective drainage of water.
[0025] 4. After the modification of the centralized ash silo, the water accumulated in the low-lying area at the top is discharged through the rainwater collection hopper and the guide pipe after large impurities are removed by the impurity screen plate. This prevents rainwater from accumulating in the low-lying area at the top of the silo, better protects the strength of the centralized ash silo, extends the service life of the centralized ash silo, keeps the silo top intact, and prevents water from entering the silo and mixing with the ash material, causing caking. This ensures the continuous production of the dust removal system and reduces the cost of use and maintenance. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0030] This application discloses a device for eliminating water accumulation and preventing corrosion on the top of a centralized ash silo 1 in a dust removal system. (Refer to...) Figure 1 The ash silo includes a centralized ash silo 1. A scraper conveyor tail wheel device is installed on the top of the centralized ash silo 1. The top of the centralized ash silo 1 bears its weight and has a center that is lower than the surrounding area. Rainwater will accumulate on the top of the centralized ash silo 1. A hole is opened in the low-lying area on the top of the centralized ash silo 1, and a diversion system 2 is installed in the hole to drain the rainwater from the top of the centralized ash silo 1. In this embodiment, the size of the hole on the top of the centralized ash silo 1 is φ120.
[0031] Reference Figure 1 The flow guiding system 2 includes an impurity screen plate 23, a rainwater collection hopper 21, and a flow guiding pipe 22. The impurity screen plate 23 has a size of φ120 and is arranged in a honeycomb pattern. The impurity screen plate 23 is located at the opening of the top hole of the centralized ash silo 1 to isolate impurities at the top of the centralized ash silo, thereby preventing the flow guiding system of this application from being blocked by impurities, which would affect the normal use of the centralized ash silo and reduce the probability of corrosion of the centralized ash silo. The rainwater collection hopper 21 is located below the impurity screen plate 23, and the inner wall of the rainwater collection hopper 21 is inclined towards the center. The two ends of the rainwater collection hopper 21 have a size of φ120. With a diameter of φ70, the guide pipe 22 is connected to the rainwater collection hopper 21. In this embodiment, the guide pipe 22 is L-shaped. The vertical section of the guide pipe 22 is connected to the bottom end of the rainwater collection hopper 21, and the horizontal section of the guide pipe 22 passes through the side wall of the centralized ash hopper 1 and is fixedly connected to the wall of the centralized ash hopper 1 by welding. The angle between the vertical section and the horizontal section of the guide pipe 22 is 93° to better discharge rainwater. The size of the guide pipe 22 is DN60. The outer surface of the guide pipe 22 is plated with a zinc protective layer to improve the corrosion resistance of the guide pipe 22, thereby extending the service life of the water accumulation elimination and corrosion prevention device of this application.
[0032] The implementation principle of the anti-water accumulation and anti-corrosion device on the top of the centralized ash silo 1 in this embodiment of the application is as follows: the water accumulated on the top of the centralized ash silo 1 will flow towards the rainwater collection hopper 21, impurities will be blocked by the impurity screen plate 23, and the water will be discharged through the guide pipe 22, thereby preventing rainwater from accumulating on the top of the centralized ash silo 1, which would lead to corrosion and damage to the centralized ash silo 1, and prevent rainwater from entering the interior of the centralized ash silo 1, causing the internal ash to clump together. This extends the service life of the centralized ash silo 1 and ensures its normal operation. After the modification of the centralized ash silo 1, the water accumulated in the low-lying area on the top of the centralized ash silo 1 is discharged through the rainwater collection hopper 21 and the guide pipe 22 after the impurity screen plate 23 removes large impurities. This prevents rainwater from accumulating in the low-lying area on the top of the silo, better protects the strength of the centralized ash silo 1, extends the service life of the centralized ash silo 1, keeps the silo top intact, and prevents water from entering the silo and mixing with the ash material, causing clumping. This ensures the continuous production of the dust removal system and reduces the cost of use and maintenance.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
