DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] For example, see Figure 1-Figure 4 The present invention provides a technical solution: a semi-dry desulfurization device, comprising a working box 2, the bottom of the working box 2 is fixedly connected to a bottom plate 1, the bottom of the bottom plate 1 is fixedly connected to a suction box 4, the top of the bottom plate 1 is fixedly connected to a feed pump 3, one end of the feed pump 3 is fixedly connected to the inner wall of the working box 2 through a connecting pipe, an impact mechanism 7 is provided at the top of the inner wall of the working box 2, and a material discharge mechanism 6 is provided on the inner wall of the working box 2, and also includes: The pushing mechanism 5 includes a connecting plate 501 fixedly connected to the bottom of the inner wall of the working box 2, a telescopic tube 502 is fixedly connected to the bottom of the inner wall of the connecting plate 501, a cleaning assembly 504 is arranged at one end of the telescopic tube 502 away from the connecting plate 501, an exhaust pipe 503 is fixedly connected to the top of the connecting plate 501, and the exhaust pipe 503 is arranged at the center of the connecting plate 501.

[0023] The cleaning component 504 includes a semicircular plate 5042 fixedly connected to one end of the telescopic tube 502, a push ring 5041 fixedly connected to the bottom of the semicircular plate 5042, and an end of the push ring 5041 away from the semicircular plate 5042 is fixedly connected to the inner wall of the connecting plate 501, a shrink tube 5048 is fixedly connected to the top of the semicircular plate 5042, and a sealing block is slidably connected to the inner wall of the shrink tube 5048. When the sealing block on the inner wall is pressed from the outside, it will be retracted to the bottom into the inside of the shrink tube 5048, so that the gas inside the shrink tube 5048 is ejected outward, and an impact pad 5043 is fixedly connected to the top of the semicircular plate 5042. The top of the impact pad 5043 is made of an elastic material that can be retracted inside and outside. When the impact pad 5043 is pressed by an object After the object is pushed, the object will be ejected outward. A clamping ring 5044 is slidably connected to the top slot of the semicircular plate 5042 through a slider. Contact feet 5046 are fixedly connected at both ends of the clamping ring 5044. A negative pressure cavity is provided inside the contact foot 5046. The surface of the contact foot 5046 is made of soft rubber material. When the negative pressure cavity inside the contact foot 5046 is impacted from the outside, it will shrink, thereby forming a pressure difference with the outside, and forming a negative pressure suction force that is transmitted into the clamping ring 5044. A passage is provided inside the clamping ring 5044, and the pressure will be transmitted to the absorption hole on the surface of the suction block 5045 through the passage. The suction block 5045 is fixedly connected to the top of the clamping ring 5044, and a pushing block 5047 is fixedly connected to the surface of the semicircular plate 5042.

[0024] The working method of the first embodiment is as follows: after the feed pump 3 discharges the absorbent into the working box 2 through the connecting pipe, the suction box 4 is started to discharge the flue gas into the working box 2 through the exhaust pipe 503. When the flue gas reacts chemically with the absorbent, solid sulfate products will be produced. When the flue gas reacts with the absorbent, compressed gas is injected into the working box 2 through the air pressure pump and flows into the telescopic tube 502. After the telescopic tube 502 is extended outward, it will push the semicircular plate 5042, so that one end of the semicircular plate 5042 tilts toward the top and tilts upward. When one end of the semicircular plate 5042 tilts toward the top, the clamping ring 5044 on its surface will slide toward the bottom, and the clamping ring 5044 slides on the surface of the semicircular plate 5042 to prevent the flue gas from contacting with the absorbent. The solid sulfate product produced by the chemical reaction is adhered to the bottom of the inner wall of the working box 2. When the clamping ring 5044 slides to the bottom to the surface of the impact pad 5043, the contact foot 5046 will come into contact with the surface of the impact pad 5043, thereby impacting the contact foot 5046, driving the clamping ring 5044 to slide to the top, and the inside of the contact foot 5046 will shrink inward after being impacted by the outside and generate negative pressure suction inside the clamping ring 5044. The generated negative pressure suction is transmitted outward through the absorption holes on the surface of the suction block 5045. The transmitted suction will absorb the flue gas and absorbent floating on the bottom of the working box 2 into the inside, which can reduce the solid sulfate product left by the reaction of the flue gas and the absorbent from adhering to the bottom of the inner wall of the working box 2.

[0025] Example 2: Based on Example 1, continue to refer to Figure 5-Figure 6 The unloading mechanism 6 includes a unloading plate 601, which is slidably connected to the inner wall groove of the working box 2 through a slider, and a telescopic pad 602 is fixedly connected to the top of the inner wall of the unloading plate 601, and one end of the telescopic pad 602 away from the top of the inner wall of the unloading plate 601 is fixedly connected to a lifting rod 603, and scraping assemblies 604 are arranged at both ends of the lifting rod 603.

[0026] The scraper assembly 604 includes a contact plate 6041, which is fixedly connected to one end of the lifting rod 603. Push arms 6042 are rotatably connected to the inner walls of the contact plate 6041 on both sides through a rotating shaft. A scraper block 6043 is fixedly connected to one end of the push arm 6042. The top part of the scraper block 6043 is made of metal material wrapped in rubber. When the scraper block 6043 contacts the inner wall of the working box 2, the chemical reactants on the inner wall can be scraped by the scraper block 6043. The inner wall of the pushing arm 6042 is slidably connected to an absorption film 6044. An absorption groove is provided on the surface of the absorption film 6044, and a cavity is provided 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 groove.

[0027] 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.

[0028] Example 3: Based on Example 1, continue to refer to Figure 7-Figure 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.

[0029] The impact mechanism 7 includes a feed pipe 705, one end of which is fixedly connected to the right side of the impact plate 704, the top of the impact plate 704 is fixedly connected to a pad 706, the top of the pad 706 is fixedly connected to a telescopic clip 707, and a telescopic component 708 is provided at one end of the sliding block 701 away from the air intake pipe 702.

[0030] The telescopic assembly 708 includes a telescopic chamber 7081, which is fixedly connected to one end of the sliding block 701, and the telescopic chamber 7081 is fixedly connected to the top of the inner wall of the working box 2. The bottom of the telescopic chamber 7081 is fixedly connected to a feeding box 7082, and air inlet holes are provided on both sides of the feeding box 7082. When the feeding pipe 705 is extended into the air inlet hole, the feeding pipe 705 will be telescoped inward into the inside of the impact plate 704, thereby compressing the folding ring 703. When the gas inside the folding ring 703 is compressed by the outside, it will be discharged into the internal passage of the impact plate 704, and flow into the inside of the feeding box 7082 from the pipe mouth of the feeding pipe 705. The inner wall of the feeding box 7082 is slidably connected to a push membrane 7083, and the bottom of the push membrane 7083 is fixedly connected to a clamping column 7084, and the bottom of the clamping column 7084 is fixedly connected to an impact membrane 7085.

[0031] The working method of the third embodiment is as follows: when one end of the semicircular plate 5042 is tilted and completely tilted up, the one end of the semicircular plate 5042 will move and approach the surface of the sliding block 701, and at this time, the bottom of the air inlet pipe 702 will be inserted into the inside of the shrink tube 5048, and the shrink tube 5048 is connected to the inside of the telescopic tube 502. When one end of the air inlet pipe 702 pushes the sealing block on the inner wall of the shrink tube 5048, the sealing block on the inner wall of the shrink tube 5048 is retracted inwardly into the inside, and at this time, one end of the air inlet pipe 702 will be inserted into the inside of the shrink tube 5048, and the gas inside the shrink tube 5048 will be discharged into the inside of the folding ring 703 through the air inlet pipe 702. The inside of the folding ring 703 receives gas and expands outward, and drives the impact plate 704 to slide outward on the inner wall of the sliding block 701. During the sliding process, the expansion clip 707 on the top of the impact plate 704 will come into contact with the top of the inner wall of the working box 2, and the solid sulfate product adhered to the top of the inner wall of the working box 2 will be scraped off by the expansion clip 707. The expansion clip 707 has expansion characteristics inside. When the top of the expansion clip 707 comes into sliding contact with the top of the inner wall of the working box 2, the expansion clip 707 will expand inward to buffer the extrusion force generated, so that the solid sulfate product adhered to the top of the inner wall of the working box 2 can be scraped off. Scrape it off and avoid leaving scratches on the top of the inner wall of the working box 2. When the impact plate 704 slides outward to the surface of the feeding box 7082, one end of the feeding tube 705 will extend into the air inlet holes on both sides of the feeding box 7082. After being pressed, one end of the feeding tube 705 will expand and contract inward, thereby squeezing the gas inside the folding ring 703 outward through the internal passage of the impact plate 704, and finally discharged into the feeding box 7082 through the pipe mouth of the feeding tube 705. When the gas injected into the feeding box 7082 drives the pushing membrane 7083 to expand and contract outward, when the pushing membrane 7083 expands and contracts outward, it drives the clamping column 7084 to move to the bottom to exhaust. Inside the tube 503, when the clamping column 7084 collides with 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 is scraped off, and after the surface of the impact membrane 7085 comes into contact with the inside of the exhaust pipe 503, it will expand and contract inward and generate negative pressure suction, which is transmitted to the surface absorption holes of the clamping column 7084. The scraped solid sulfate product is absorbed into the interior through the absorption holes on the surface of the clamping column 7084. The solid sulfate product generated after the surface flue gas and the absorbent are mixed can block the inside of the exhaust pipe 503, thereby preventing the flue gas from passing through the exhaust pipe 503 and being discharged into the working box 2.
