Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection, and specifically relates to a semi-dry desulfurization device. Background Technique

[0002] The semi-dry desulfurization device is an important environmental protection device for reducing sulfur dioxide emissions in industrial waste gas. Semi-dry desulfurization mainly uses powdered or granular absorbents to react with sulfur-containing waste gas under specific reaction conditions to remove sulfur dioxide from the waste gas. After the sulfur-containing waste gas enters the desulfurization device, it is fully mixed with the sprayed absorbent, and under certain temperature and humidity conditions, the absorbent reacts chemically with sulfur dioxide.

[0003] The patent application with the application number 202010997381.0 discloses a semi-dry desulfurization device, including a desulfurization cabinet and a smoke outlet pipe connected to the top end inside the desulfurization cabinet. Among them, it also includes a scale scraping mechanism, a smoke inlet pipe, a chip discharge funnel, and a flue gas filtering mechanism. A lifting component is arranged inside the desulfurization cabinet; a chip discharge pipe is arranged at the bottom of the chip discharge funnel, and an anti-sticking wall component is arranged beside the desulfurization cabinet.

[0004] However, this patent also has the following deficiencies. That is, when the sulfur-containing waste gas enters the desulfurization device, it is fully mixed with the sprayed absorbent, and under certain temperature and humidity conditions, the absorbent reacts chemically with sulfur dioxide to generate solid products such as sulfates or sulfites. And a part of the generated solid sulfate products will precipitate and adhere inside the desulfurization box. If not cleaned in time, it will affect the subsequent desulfurization work. In view of this situation, a semi-dry desulfurization device is specifically proposed. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a semi-dry desulfurization device, which has the following beneficial effects:

[0017] 1. In the present invention, by providing a cleaning component, when the inside of the contact foot is subjected to an external impact, it will contract inward and generate a negative pressure suction force inside the clamping ring. The generated negative pressure suction force is transmitted outward through the absorption holes on the surface of the suction block, and the transmitted suction force will absorb the flue gas and absorbent floating at the bottom of the working box into the inside.

By setting this mechanism, the content of the solid sulfate products adhered to the inner wall of the working box can be reduced, and the solid sulfate products that are difficult to clean on the inner wall of the working box can also be removed.

[0019] 3. In the present invention, by providing an impact mechanism, when the top of the telescopic clip makes a sliding contact with the top inner wall of the working box, the telescopic clip will contract inward to buffer the generated extrusion force. By setting this mechanism, the solid sulfate products adhered to the top inner wall of the working box can be scraped off, and scratches can be avoided on the top inner wall of the working box.

[0020] 4. The present invention is provided with a telescopic component. When the clamping column impacts the solid sulfate product adhered inside the exhaust pipe, the solid sulfate product adhered inside the exhaust pipe is scraped off. The scraped solid sulfate product is absorbed into the interior through the absorption holes on the surface of the clamping column. By setting this component, it is possible to prevent the solid sulfate product generated after the surface flue gas is mixed with the absorbent from blocking the interior of the exhaust pipe, thereby preventing the flue gas from passing through the exhaust pipe and entering the working box interior.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1. Please refer to Figures 1 - 4 , the present invention provides a technical solution: a semi-dry desulfurization device, including a working box 2, the bottom of the working box 2 is fixedly connected with a bottom plate 1, the bottom of the bottom plate 1 is fixedly connected with a suction box 4, the top of the bottom plate 1 is fixedly connected with a feed pump 3, one end of the feed pump 3 is fixedly connected with the inner wall of the working box 2 through a connecting pipe, the top of the inner wall of the working box 2 is provided with an impact mechanism 7, the inner wall of the working box 2 is provided with a feeding mechanism 6, and further includes:

[0033] A pushing mechanism 5, including a connecting plate 501 fixedly connected to the bottom of the inner wall of the working box 2, the bottom of the inner wall of the connecting plate 501 is fixedly connected with a telescopic tube 502, one end of the telescopic tube 502 away from the connecting plate 501 is provided with a cleaning component 504, the top of the connecting plate 501 is fixedly connected with an exhaust pipe 503, and the exhaust pipe 503 is arranged at the center of the connecting plate 501.

[0034] The cleaning component 504 includes a semi-circular plate 5042 fixedly connected to one end of the telescopic tube 502. A pushing ring 5041 is fixedly connected to the bottom of the semi-circular plate 5042. One end of the pushing ring 5041 away from the semi-circular plate 5042 is fixedly connected to the inner wall of the connecting plate 501. A contraction tube 5048 is fixedly connected to the top of the semi-circular plate 5042. A sealing block is slidably connected to the inner wall of the contraction tube 5048. When the sealing block on its inner wall is externally pressed, it will retract into the interior of the contraction tube 5048 towards the bottom, thereby ejecting the gas inside the contraction tube 5048 outwards. An impact pad 5043 is fixedly connected to the top of the semi-circular plate 5042. The top of the impact pad 5043 is made of an elastic material that can be telescoped in and out. When the impact pad 5043 is pushed by an object, it will eject the object outwards. A material clamping ring 5044 is slidably connected to the slot on the top of the semi-circular plate 5042 through a slider. Contact feet 5046 are fixedly connected to both ends of the material clamping ring 5044. A negative pressure cavity is formed inside the contact feet 5046. The surface of the contact feet 5046 is made of a soft rubber material. When the negative pressure cavity inside the contact feet 5046 is externally impacted, it will contract, thereby forming a pressure difference with the outside and forming a negative pressure suction force that is transmitted into the material clamping ring 5044. A passage is formed inside the material clamping ring 5044, and through this passage, it will be transmitted to the absorption holes on the surface of the material suction block 5045. A material suction block 5045 is fixedly connected to the top of the material clamping ring 5044. A pushing block 5047 is fixedly connected to the surface of the semi-circular plate 5042.

[0035] Working mode of the first embodiment: After the feed pump 3 discharges the absorbent into the interior of the working box 2 through the connecting pipe, the suction box 4 is started to discharge the flue gas into the interior of the working box 2 through the exhaust pipe 503. When a chemical reaction occurs between the flue gas and the absorbent, solid sulfate products will be generated. During the reaction between the flue gas and the absorbent, compressed gas is injected into the interior of the working box 2 through the air pressure pump and flows into the telescopic pipe 502. After the telescopic pipe 502 expands outward, it will push the semi-circular plate 5042, causing one end of the semi-circular plate 5042 to tilt upward towards the top. When one end of the semi-circular plate 5042 tilts upward towards the top, the clamping ring 5044 on its surface will slide downward. By sliding the clamping ring 5044 on the surface of the semi-circular plate 5042, it is avoided that the solid sulfate products generated by the chemical reaction between the flue gas and the absorbent adhere to the bottom inner wall of the working box 2. When the clamping ring 5044 slides downward to hit the surface of the impact pad 5043, the contact foot 5046 will come into contact with the surface of the impact pad 5043, thereby hitting the contact foot 5046 and driving the clamping ring 5044 to slide upward. After being externally impacted, the inside of the contact foot 5046 will contract inward and generate a negative pressure suction force inside the clamping ring 5044. The generated negative pressure suction force is transmitted outward through the absorption holes on the surface of the absorbent block 5045. The transmitted suction force will absorb the flue gas and absorbent floating at the bottom of the working box 2 into the interior, which can reduce the adhesion of the solid sulfate products left by the reaction between the flue gas and the absorbent to the bottom inner wall of the working box 2.

[0036] Embodiment 2: On the basis of Embodiment 1, continue to refer to Figures 5 - 6 , the blanking mechanism 6 includes a blanking plate 601. The blanking plate 601 is slidably connected to the inner wall slot of the working box 2 through a slider. A telescopic pad 602 is fixedly connected to the top of the inner wall of the blanking plate 601. One end of the telescopic pad 602 away from the top of the inner wall of the blanking plate 601 is fixedly connected to a lifting rod 603. Scraping components 604 are arranged at both ends of the lifting rod 603.

[0037] The scraping component 604 includes a contact plate 6041. The contact plate 6041 is fixedly connected to one end of the lifting rod 603. The two sides of the inner wall of the contact plate 6041 are rotatably connected to a pushing arm 6042 through a rotating shaft. One end of the pushing arm 6042 is fixedly connected to a scraping block 6043. The top part of the scraping block 6043 is made of metal wrapped with rubber. When the scraping block 6043 contacts the inner wall of the working box 2, the chemical reactants on its inner wall can be scraped by the scraping block 6043. An absorption film 6044 is slidably connected to the inner wall of the pushing arm 6042. Absorption grooves are formed on the surface of the absorption film 6044, and a cavity is formed inside the absorption film 6044. The absorption film 6044 is made of a film material. When the absorption film 6044 contacts the surface of the working box 2, external substances can be absorbed through the absorption grooves.

[0038] The working method of the second embodiment is as follows: when one end of the semicircular plate 5042 tilts toward the top and tilts up, the pushing block 5047 pushes the lifting rod 603, and the lifting rod 603 slides toward the top after being pushed. When the lifting rod 603 slides toward the top, it squeezes one end of the telescopic pad 602, driving one end of the telescopic pad 602 to telescope inwardly. When the lifting rod 603 slides toward the top, it drives the contact plate 6041 to move upward, and when the contact plate 6041 moves upward, it comes into contact with the inner wall of the working box 2. At this time, the gas generated by the inward expansion and contraction of the expansion pad 602 will flow into the internal cavity of the contact plate 6041 through the inside of the lifting rod 603, and will flow into the inside of the push arm 6042 through the cavity inside the contact plate 6041. The gas will be injected into the absorption film 6044 inside the push arm 6042, thereby driving the absorption film 6044 to expand and contract outward and extend from the inside of the push arm 6042 to contact the inner wall of the working box 2. Since the surface of the absorption film 6044 has a certain elasticity, when the absorption film 6044 is in contact with the working box 2 When the inner wall of the working box 2 is in contact, the pushing arm 6042 is pushed, so that the pushing arm 6042 swings inside the contact plate 6041. When one end of the pushing arm 6042 swings to the inner wall of the working box 2, the solid sulfate product adhering to the inner wall of the working box 2 can be scraped off by the scraping block 6043, and the absorption film 6044 contacts the inside of the working box 2. The absorption groove on the surface of the absorption film 6044 absorbs the scraped solid sulfate product into the interior. When one end of the semicircular plate 5042 is completely tilted to the top, After rising, the pushing block 5047 on the surface of the semicircular plate 5042 will leave the surface of the lifting rod 603, and the lifting rod 603 will slide downward without being pushed upward, and drive the telescopic pad 602 to telescope downward. At this time, the gas discharged from the inside of the telescopic pad 602 will flow back into the inside, and when the absorption film 6044 loses the gas push, it will telescope inward into the inside of the pushing arm 6042, which can reduce the content of solid sulfate products adhered to the inner wall of the working box 2, and can also remove the solid sulfate products that are difficult to clean the inner wall of the working box 2.

[0039] Example 3: Based on Example 1, continue to refer to Figures 7 - 8 The impact mechanism 7 includes a sliding block 701, which is fixedly connected to the top of the inner wall of the working box 2. The inner wall of the sliding block 701 is slidably connected to the impact plate 704 through a sliding block. The bottom of the sliding block 701 is fixedly connected to an air inlet pipe 702. The left side of the inner wall of the sliding block 701 is fixedly connected to a folding ring 703. The folding ring 703 has the characteristics of retractable reset, and an air cavity is opened inside it. When compressed gas is injected into the interior, it will expand and retract outward. The end of the folding ring 703 away from the left side of the inner wall of the sliding block 701 is fixedly connected to the left side of the impact plate 704.

[0040] The impact mechanism 7 includes a feeding pipe 705. One end of the feeding pipe 705 is fixedly connected to the right side of the impact plate 704. A backing plate 706 is fixedly connected to the top of the impact plate 704. A telescopic clip 707 is fixedly connected to the top of the backing plate 706. One end of the sliding block 701 away from the air inlet pipe 702 is provided with a telescopic assembly 708.

[0041] The telescopic assembly 708 includes a telescopic cavity 7081. The telescopic cavity 7081 is fixedly connected to one end of the sliding block 701 and is also fixedly connected to the top inner wall of the working box 2. A feeding box 7082 is fixedly connected to the bottom of the telescopic cavity 7081. Air inlet holes are formed on both sides of the feeding box 7082. After the feeding pipe 705 extends into the air inlet holes, the feeding pipe 705 will telescopically move inward into the impact plate 704, thereby compressing the folding ring 703. When the gas inside the folding ring 703 is externally compressed, it will be discharged into the internal passage of the impact plate 704 and pour into the inside of the feeding box 7082 from the pipe orifice of the feeding pipe 705. A pushing membrane 7083 is slidably connected to the inner wall of the feeding box 7082. A clamping column 7084 is fixedly connected to the bottom of the pushing membrane 7083. An impact membrane 7085 is fixedly connected to the bottom of the clamping column 7084.

[0042] Working mode of the third embodiment: When one end of the semi-circular plate 5042 is tilted and completely lifted, one end of the semi-circular plate 5042 will move and approach the surface of the sliding block 701. At this time, the bottom of the air inlet pipe 702 will be inserted into the inside of the contraction pipe 5048, and the contraction pipe 5048 is connected to the inside of the telescopic pipe 502. When one end of the air inlet pipe 702 pushes the sealing block on the inner wall of the contraction pipe 5048, the sealing block on the inner wall of the contraction pipe 5048 will retract inward into the inside. At this time, one end of the air inlet pipe 702 will be inserted into the inside of the contraction pipe 5048. The gas inside the contraction pipe 5048 will be discharged into the inside of the folding ring 703 through the air inlet pipe 702. After receiving the gas, the inside of the folding ring 703 will expand outward and drive the impact plate 704 to slide outward on the inner wall of the sliding block 701. During the sliding process, the telescopic clip 707 on the top of the impact plate 704 will come into contact with the top inner wall of the working box 2. The solid sulfate product adhered to the top inner wall of the working box 2 will be scraped off by the telescopic clip 707. The telescopic clip 707 has telescopic characteristics inside. When the top of the telescopic clip 707 makes a sliding contact with the top inner wall of the working box 2, the telescopic clip 707 will retract inward to buffer the generated extrusion force, and the solid sulfate product adhered to the top inner wall of the working box 2 can be scraped off, and scratches on the top inner wall of the working box 2 can be avoided. When the impact plate 704 slides outward to the surface of the feeding box 7082, one end of the feeding pipe 705 will extend into the two air inlet holes on both sides of the feeding box 7082. After one end of the feeding pipe 705 is pressed, it will retract inward, so as to squeeze the gas inside the folding ring 703 outward through the internal passage of the impact plate 704, and finally discharge it into the feeding box 7082 through the pipe orifice of the feeding pipe 705. When the gas injected into the feeding box 7082 drives the pushing membrane 7083 to expand outward, after the pushing membrane 7083 expands outward, it will drive the clamping column 7084 to move downward into the exhaust pipe 503. When the clamping column 7084 impacts the solid sulfate product adhered to the inside of the exhaust pipe 503, the solid sulfate product adhered to the inside of the exhaust pipe 503 will be scraped off. After the surface of the impact membrane 7085 comes into contact with the inside of the exhaust pipe 503, it will retract inward and generate a negative pressure suction force to be transmitted to the absorption holes on the surface of the clamping column 7084. The scraped solid sulfate product will be absorbed into the inside through the absorption holes on the surface of the clamping column 7084, which can prevent the solid sulfate product generated after the flue gas is mixed with the absorbent from blocking the inside of the exhaust pipe 503, so that the flue gas cannot be discharged into the working box 2 through the exhaust pipe 503.
