[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] like Figure 1-2 As shown, this embodiment proposes an anti-clogging biological desulfurization tower, which mainly includes a tower body 1. The tower body 1 includes basic desulfurization structures such as an air inlet 11, an air outlet 12, and a plurality of desulfurization plates. A filter screen 2 is provided inside the tower body 1. The filter screen 2 is located between each desulfurization plate and the air inlet 11. With the help of the physical filtering effect of the filter screen 2, the solidified particulate matter in the sulfide gas is filtered to prevent these solidified particulate matter from contacting the desulfurization plate, thereby solving the problem of solidified particulate matter sticking to the desulfurization plate and gradually accumulating to form blockage over time.
[0028] At the same time, it is considered that the solidified particulate matter filtered through the filter 2 may adhere to the filter 2 over time, and block the mesh of the filter 2 over time, which will also cause the gas channel inside the tower body 1 to be blocked, resulting in a decrease in the gas flow rate or even a failure of gas flow; therefore, the tower body 1 is provided with an anti-blocking mechanism 3 at the filter 2, and the filter 2 is cleaned with the help of the anti-blocking mechanism 3 to prevent the filter 2 from being blocked, thereby ensuring that the gas channel inside the tower body 1 is sufficiently unobstructed; and because the desulfurization plate may contain a certain amount of biological solution, the cleaning work of the anti-blocking mechanism 3 mainly acts on the filter 2, which can effectively prevent the cleaning work of the anti-blocking mechanism 3 from damaging the biological solution on the desulfurization plate, thereby avoiding affecting the desulfurization work of the desulfurization tower.
[0029] The anti-blocking mechanism 3 mainly includes an anti-blocking scraper strip 31, a driving motor 32, and a linkage body 33 for linking the anti-blocking scraper strip 31 to the output shaft of the driving motor 32. The linkage body 33 is rotatably connected to the inside of the tower body 1. Since the linkage body 33 is linked to the output shaft of the driving motor 32, the rotational movement of the linkage body 33 inside the tower body 1 is controlled by the driving motor 32, that is, the rotational movement of the linkage body 33 has sufficient stability and durability; a cleaning brush 34 is provided on the anti-blocking scraper strip 31, and the cleaning brush 34 is located at the anti-blocking scraper strip 31. One end is away from the linkage body 33 and is fixedly connected to the anti-blocking scraper strip 31. At the same time, one end of the cleaning brush 34 is away from the anti-blocking scraper strip 31 and abuts against the filter screen 2. In this way, when the anti-blocking scraper strip 31 is linked with the linkage body 33 and the output shaft of the driving motor 32, the cleaning brush 34 will rotate on the filter screen 2, thereby realizing the cleaning work of the filter screen 2. The length of the cleaning brush 34 is equal to the diameter of the filter screen 2, which can quickly clean the blockage on the surface of the filter screen 2 during the rotation process, thereby improving the cleaning effect of the anti-blocking mechanism 3.
[0030] The cleaning brush 34 in this embodiment is preferably made of nylon material which is corrosion-resistant and has a certain elasticity to prevent the cleaning brush 34 from being corroded due to long-term exposure to sulfide gas, thereby affecting the normal operation of the anti-blocking mechanism 3.
[0031] like Figure 4-5 As shown, the linkage body 33 in this embodiment includes a connecting disk 331 and a plurality of connecting rods 332. The connecting disk 331 is provided with a connecting hole at one end close to the driving motor 32, and the output shaft of the driving motor 32 is fixedly connected in the connecting hole, so as to realize the linkage between the connecting disk 331 and the output shaft of the driving motor 32; the two ends of each connecting rod 332 are respectively fixedly connected to the anti-blocking scraper strip 31 and the connecting disk 331, so as to realize the linkage between the anti-blocking scraper strip 31 and the linkage body 33, and the fixed connection method between the anti-blocking scraper strip 31 and the linkage body 33 is preferably an integrated molding connection method, which fully ensures the stability of the connection between the two.
[0032] A guide body 311 is provided at one end of the anti-blocking scraper strip 31 away from the cleaning brush 34. The guide body 311 is an inverted triangular structure, which allows the rising sulfide gas to continue to rise along the outer surface of the guide body 311, thereby preventing a small part of the sulfide gas from staying in the anti-blocking scraper strip 31 for a long time, corroding the anti-blocking scraper strip 31 and affecting the service life of the anti-blocking mechanism 3; the guide body 311 is fixedly connected to the anti-blocking scraper strip 31, so that the guide body 311 can rotate with the anti-blocking scraper strip 31, and the fixed connection between the two is preferably integrally formed to make the connection between the two more stable.
[0033] The connecting rods 332 are symmetrically distributed with the anti-blocking scraper strip 31 as the center, so that the reaction force exerted on the anti-blocking scraper strip 31 when driving the cleaning brush 34 to perform cleaning work can maintain a certain balance and be evenly distributed along the entire linkage body 33, thereby ensuring the stability of the overall structure of the anti-blocking mechanism 3; the flow guide 311 is located between adjacent connecting rods 332, which facilitates the flow guide 311 to contact the rising sulfide gas, so that the flow guide 311 can better guide the sulfide gas to rise.
[0034] A guide portion 3321 is provided on each connecting rod 332, and each guide portion 3321 is at the same horizontal height as the air inlet 11, that is, the guiding function of the guide portion 3321 mainly acts on the air inlet 11, to prevent the connecting rod 332 from being driven by the driving motor 32 to move to the air inlet 11 under certain circumstances, thereby affecting the air intake operation of this embodiment. The cross-section of each guide portion 3321 is a triangular structure, and when the guide portion 3321 corresponds to the air inlet 11, the width of the end of the guide portion 3321 close to the air inlet 11 is smaller than the width of the end of the guide portion 3321 away from the air inlet 11, thereby facilitating the movement of the sulfide gas along the outer surface of the guide portion 3321.
[0035] The connecting disk 331 is provided with a discharge structure 4, which includes a receiving ring 41 and a plurality of discharge ports 42. The receiving ring 41 is fixedly connected to the connecting disk 331. With the help of the mutual cooperation between the receiving ring 41 and the connecting disk 331, a receiving cavity is formed on the connecting disk 331 to receive the deposits cleaned by the cleaning brush 34 or the reactants generated after the sulfide gas reacts with the desulfurization plate. The receiving cavity is in an active state with the action of the driving motor 32 to prevent these substances from forming solid waste due to being in a static state inside the tower body 1 for a long time, and to facilitate the discharge of these reactants. The discharge ports 42 are evenly distributed around the connecting disk 331 in a circle and all penetrate the connecting disk 331, so that the reactants can flow from the connecting disk 331 to the bottom of the tower body 1 for discharge.
[0036] Furthermore, since the driving motor 32 is also located at the bottom of the tower body 1, in order to prevent these reactants from affecting the normal operation of the driving motor 32, Figure 2-3 As shown, the motor seat for installing the driving motor 32 in this embodiment adopts a suspended design, and is fixed at the hollow position at the bottom of the tower body 1 by a plurality of support rods, and the motor seat completely wraps the driving motor 32, making it difficult for the reactants to contact the driving motor 32, thereby ensuring the stability of the operation of this embodiment.
[0037] At the same time, the support rod should preferably be a support rod with a circular shape or other structure that is not easy to accumulate materials, so as to prevent the excrement discharged from the connecting plate 331 from accumulating on the support rod, causing difficulty in excretion in this embodiment.
[0038] The drive motor 32 in this embodiment is preferably a motor with good heat resistance such as a brushless direct-flow motor to prevent the drive motor 32 from being adversely affected by the heat generated by its long-term operation due to the closed motor base, thereby improving the stability of the operation of this embodiment.
[0039] like Figure 5 As shown, the projection surface of each discharge port 42 in this embodiment on the horizontal plane is tangent to the inner ring of the projection surface of the containing ring 41 on the horizontal plane, that is, each discharge port 42 is located at the outer diameter of the connecting disk 331, which facilitates the reactants in the containing cavity to quickly enter the discharge port 42 for discharge under the action of the centrifugal force generated when the connecting disk 331 rotates, thereby improving the discharge efficiency.
[0040] A first drainage body 411 is provided on the end of the containing ring 41 away from the connecting disk 331. The longitudinal section of the first drainage body 411 is a triangular structure, and the end of the first drainage body 411 close to the connecting disk 331 is wider than the end of the first drainage body 411 away from the connecting disk 331, so that the blockages cleaned from the filter 2 and the reactants dropped from the desulfurization plate can enter the containing cavity conveniently, and prevent the blockages and reactants from accumulating on the containing ring 41; a second drainage body 3311 is provided on the connecting disk 331, and the second drainage body 3311 is a conical structure, that is, the blockages and reactants falling into the containing cavity can be quickly moved along the second drainage body 3311 to the locations of the discharge ports 42, further improving the discharge efficiency of this embodiment.
[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
