Description

Technical Field

[0001] The utility model relates to the technical field of flue gas desulfurization, in particular to a flue gas desulfurization device for avoiding blockage of a filtering mechanism. Background Technique

[0002] The design and manufacture of dry desulfurization equipment must meet the process requirements, and usually include parts such as a desulfurizer, a desiccant supply system, a separation device, a regeneration device, etc. It is widely used in industrial fields such as biogas power generation, coal-fired power plants, and boilers, and is especially suitable for occasions with small gas volume and high desulfurization accuracy.

[0003] Dry desulfurization mainly uses powdered or granular absorbents (such as limestone, dolomite, slaked lime, etc.) to chemically react with SO2 in the flue gas in a dry state to generate solid products (such as calcium sulfate, magnesium sulfate, etc.), thereby achieving the purpose of desulfurization.

[0004] In the existing technical solutions, it usually involves guiding the flue gas to a device filled with a solid absorbent. When the flue gas passes through the absorbent, sulfur dioxide in it chemically reacts with the absorbent to generate solid desulfurization products; however, in actual applications, sulfur dioxide mostly only reacts with the absorbent on the surface during circulation, and the remaining part of the absorbent cannot fully react with sulfur dioxide, resulting in the problem of waste due to insufficient use of the absorbent. Summary of the Invention

[0005] The purpose of the utility model is to provide a flue gas desulfurization device for avoiding blockage of a filtering mechanism. The granular absorbent on the breathable backing plate can vibrate up and down, so that the position of the granular absorbent can be adjusted during operation, enabling the granular absorbent to fully react with sulfur dioxide in the flowing flue gas, so as to solve the problems raised in the above background technique.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0026] The present utility model provides a technical solution:

[0027] Please refer to Figures 1 to 4, a flue gas desulfurization device for avoiding clogging of a filtering mechanism, comprising a desulfurization tank 1. A flue gas injection pipe 2 is fixedly communicated with the bottom end of the desulfurization tank 1, and a flue gas discharge pipe 3 is fixedly communicated with the top end of the desulfurization tank 1. An installation reaction assembly 7 is arranged inside the desulfurization tank 1. The installation reaction assembly 7 includes an assembly frame 701 fittingly installed inside the desulfurization tank 1. Ventilation backing plates 702 are fixedly installed at both the upper and lower ends of the assembly frame 701. Communication columns 703 penetrate through the middle of the ventilation backing plates 702. The communication columns 703 are of a hollow structure and there are multiple of them. Through holes 704 are formed on the outer end faces of the communication columns 703, and the number of the through holes 704 is set to be multiple. Assembly cavities 5 are formed in the inner walls on both the left and right sides of the desulfurization tank 1. Vibration anti-clogging assemblies 6 are arranged inside the assembly cavities 5. A vibration driving assembly 4 is arranged below the installation reaction assembly 7 inside the desulfurization tank 1.

[0028] By adopting the above technical solution, during use, the flue gas to be filtered and desulfurized is introduced into the desulfurization tank 1 through the flue gas injection pipe 2. By driving the vibration driving assembly 4 through the flue gas injection pipe 2, the vibration driving assembly 4 can be driven to move. By driving the vibration anti-clogging assembly 6 through the vibration driving assembly 4, the installation reaction assembly 7 can be driven to vibrate up and down. When the assembly frame 701 vibrates up and down, the granular absorbent on the ventilation backing plate 702 can vibrate up and down. In this way, the position of the granular absorbent can be adjusted during operation, so that the granular absorbent can fully react with sulfur dioxide in the flowing flue gas. Moreover, the up-and-down vibration of the ventilation backing plate 702 can also prevent dust in the flue gas from adhering to the end face of the ventilation backing plate 702, affecting the air permeability of the ventilation backing plate 702. At the same time, the arranged communication columns 703 can also guide sulfur dioxide in the flue gas to react with the granular absorbent through the through holes 704. In this way, the contact area between sulfur dioxide in the flue gas and the granular absorbent can be increased, thereby improving the effect of flue gas desulfurization.

[0029] Specifically, such as Figures 2 to 4As shown in the figure, the vibration anti-blocking assembly 6 includes an assembly plate 601 fixedly installed on the side wall of the desulfurization tank 1. The assembly plate 601 serves as a support to avoid problems such as unstable assembly of the spring 602, connecting plate 603, filling reaction assembly 7, etc. Springs 602 are fixedly installed at both ends of the upper end surface of the assembly plate 601, and a connecting plate 603 is fixedly installed at the upper end of the spring 602; a fixing block 604 is fixedly installed on the inner side wall of the connecting plate 603, and the fixing block 604 is fixedly connected to the assembly frame 701; a moving groove 605 corresponding to the fixing block 604 is opened on the inner side wall of the desulfurization tank 1. A bladder pad 606 is fixedly installed below the fixing block 604 inside the moving groove 605. The bottom end of the bladder pad 606 is fixed to the bottom end surface of the moving groove 605, and the top end of the bladder pad 606 is fixed to the bottom end surface of the fixing block 604. In this way, when the fixing block 604 moves up and down, it can drive the bladder pad 606 to move up and down, so that the moving groove 605 can be blocked by the bladder pad 606, thereby preventing flue gas from escaping from the moving groove 605 and improving the filtering effect of sulfur dioxide in the flue gas.

[0030] The vibration driving assembly 4 includes a rotating shaft 402 rotatably installed on the inner wall of the desulfurization tank 1. A driving blade 401 is fixedly installed at the middle position of the shaft wall of the rotating shaft 402; the number of driving blades 401 is six and they are distributed in a circular array. The output port of the flue gas injection pipe 2 corresponds to the driving blade 401, and the force of the flue gas injected by the flue gas injection pipe 2 to drive the driving blade 401 to rotate is greater than the resistance received by the driving blade 401; at both ends of the rotating shaft 402 located in the assembly cavity 5, a dial rod 403 is fixedly installed, and a limiting groove 404 is opened on the assembly plate 601 outside the dial rod 403.

[0031] By adopting the above technical solution, during use, the flue gas to be filtered and desulfurized is introduced into the desulfurization tank 1 through the flue gas injection pipe 2. The continuous input of the flue gas in the flue gas injection pipe 2 can drive the corresponding driving blade 401 to rotate. In this way, the driving blade 401 can drive the rotating shaft 402 to rotate. Thus, the rotating shaft 402 can drive the lever 403 to rotate. The lever 403 can push the connecting plate 603 to move upward through rotating in the limiting groove 404. When the lever 403 rotates and separates from the connecting plate 603, the connecting plate 603 will vibrate up and down under the action of the spring 602. The up and down vibration of the connecting plate 603 can drive the assembly frame 701 to vibrate through the fixed block 604, thereby driving the entire filling reaction assembly 7 to vibrate. In this way, when the filling reaction assembly 7 vibrates, it can prevent blockage problems. At the same time, vibration can effectively prevent the absorbent particles from agglomerating and caking in the reaction assembly, keep the particles in a dispersed state, and reduce the risk of blockage. At the same time, through the cooperation of the vibration drive assembly 4 and the filling reaction assembly 7, the flow energy of the flue gas itself can be used to drive the vibration of the reaction assembly without an additional power source, thereby significantly reducing energy consumption. This natural driving method conforms to the environmental protection concept of energy conservation and emission reduction.

[0032] Working principle: During use, the flue gas to be filtered and desulfurized is introduced into the desulfurization tank 1 through the flue gas injection pipe 2. The continuous input of the flue gas in the flue gas injection pipe 2 can drive the corresponding driving blade 401 to rotate. In this way, the driving blade 401 can drive the rotating shaft 402 to rotate. Thus, the rotating shaft 402 can drive the lever 403 to rotate. The lever 403 can push the connecting plate 603 to move upward through rotating in the limiting groove 404. When the lever 403 rotates and separates from the connecting plate 603, the connecting plate 603 will vibrate up and down under the action of the spring 602. The up and down vibration of the connecting plate 603 can drive the assembly frame 701 to vibrate through the fixed block 604. When the assembly frame 701 vibrates up and down, the granular absorbent on the breathable backing plate 702 can vibrate up and down. In this way, the granular absorbent can fully react with the sulfur dioxide in the flowing flue gas. The up and down vibration of the breathable backing plate 702 can also prevent the dust in the flue gas from adhering to the end face of the breathable backing plate 702 and affecting the air permeability of the breathable backing plate 702. At the same time, the provided connecting column 703 can also guide the sulfur dioxide in the flue gas to react with the granular absorbent through the through hole 704, improving the effect of flue gas desulfurization.
