Abstract
Description
Technical Field
[0001] The invention relates to the technical field of cement denitration, and in particular to a cement kiln gasification furnace alternative fuel denitration device. Background Art
[0002] Cement kiln gasification furnace technology is an environmentally friendly technology that uses high-temperature oxidation to process garbage into thermal energy. It is a device that can convert biomass materials into gas, and the biomass charcoal formed by pyrolysis can fall to the bottom of the furnace through the screen and accumulate. Among them, the biomass energy denitrification technology uses the reducing compounds produced by biomass reactions, such as NH3, ammonia water, urea, etc., to react with NOx in the flue gas at high temperatures to generate nitrogen molecules and water vapor, thereby achieving the purpose of reducing NOx to N2. This technology obtains biomass energy from renewable resources, greatly reduces dependence on traditional fossil energy, and reduces the emission of greenhouse gases such as carbon dioxide. Compared with traditional SCR (selective catalytic reduction) and SNCR (selective non-catalytic reduction) technologies, biomass energy denitrification technology has the advantages of energy saving, environmental protection, low cost and flexible operation. Biomass charcoal is a carbon material made from biomass resources (such as agricultural waste, forestry product processing residues, food processing waste, etc.) through pyrolysis, carbonization and other processes. This carbon material can not only be used directly as fuel, but also compared with traditional fuels such as coal, the use of biochar can reduce sulfur emissions, thereby reducing pollution to the environment.
[0003] After searching, the existing patent (Announcement No.: CN214470146U) discloses a novel cement kiln pyrolysis gasification furnace alternative fuel denitrification device, which includes a pyrolysis furnace, a decomposition furnace, a gas transmission mechanism, and a feeding mechanism. The pyrolysis furnace is provided with a gas transmission mechanism inside, and the pyrolysis furnace is provided with a feeding mechanism outside; the feeding mechanism includes a motor, a threaded rod, a bevel gear four, a baffle, a positioning rod, a pulley one, a belt, a pulley two, and a feeding bucket. One end of the threaded rod is fixedly connected to the output end of the motor through a coupling. By setting the feeding mechanism, the threaded rod is driven to rotate by the motor, the threaded rod drives the baffle to move, and at the same time, the threaded rod drives the pulley one to rotate, and the pulley two drives the feeding bucket to rotate. When the biomass char formed by pyrolysis and carbonization in the pyrolysis furnace falls to the bottom, it can be sent to the decomposition furnace for use as fuel, thereby reducing the use of coal powder, reducing the generation of nitrogen oxides, reducing the use of reducing agents, and saving the production cost of the enterprise.
[0004] However, there are still some shortcomings in the above scheme:
[0005] The feeding of biomass raw materials in the pyrolysis furnace needs to be done manually or by setting up additional conveying equipment, which is troublesome and inconvenient to operate, increases the cost of use, and has a low degree of automation;
[0006] It moves the baffle by driving the threaded rod on the feeding mechanism to rotate, thereby moving the biochar into the feeding barrel. However, since the height of the baffle remains unchanged during the reciprocating movement, when the baffle moves back (towards the direction away from the feeding barrel), the baffle is likely to push the biochar remaining at the bottom of the pyrolysis furnace or the biochar just dropped from the combustion zone of the pyrolysis furnace away from the feeding barrel, thereby affecting the normal feeding work.

Example
[0050] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Fig. 9 A pushing mechanism 9 is provided at the inner side of the bottom of the pyrolysis furnace 2, and the pushing mechanism 9 can be driven by the transmission mechanism 4. The pushing mechanism 9 includes two supporting parts 91 symmetrically arranged at the bottom of the pyrolysis furnace 2, a pushing plate 96 is provided between the two supporting parts 91, a transverse axis 95 is fixedly connected to the top of the pushing plate 96, and both ends of the transverse axis 95 are respectively connected to the two supporting parts 91 through connecting parts 94, and support seats 93 are provided at the lower sides of the two connecting parts 94.
[0051] Specifically, the support component 91 includes a support frame 911 fixedly connected to the upper end surface of the bottom of the pyrolysis furnace 2, a built-in block 913 is arranged inside the upper side of the support frame 911, a track 912 is formed between the built-in block 913 and the support frame 911, a baffle 915 is rotatably connected to one side of the bottom of the track 912 through a rotating shaft, a U-shaped frame 914 is fixedly connected between the built-in block 913 and the support frame 911, and a T-shaped slot 916 is provided on the outer wall of the support frame 911 located on the lower side of the track 912.
[0052] Furthermore, the support seat 93 includes an outer frame 931 and an inner plate 933, the inner plate 933 is fixedly connected to the horizontal axis 95, the inner plate 933 slides and extends to the inside of the outer frame 931, and a support spring 934 is connected between the bottom end of the inner plate 933 and the outer frame 931, a T-block 932 is fixedly connected to the outer wall of the outer frame 931, the T-block 932 is slidingly fitted with the T-slot 916, one of the support frames 911 is rotatably connected to the inside of a screw rod 92, and the other support frame 911 is fixedly connected to the inside of a guide rod 97, the screw rod 92 is threadedly penetrated into the inside of the outer frame 931, and the guide rod 97 slides through the inside of the outer frame 931.
[0053] Furthermore, the connecting member 94 includes a connecting plate 941 fixedly connected to the side wall of the inner plate 933, and the upper end of the connecting plate 941 is rotatably connected to a roller 942, and the roller 942 is slidably sleeved on the inner side of the track 912. A limit plate 943 is respectively sleeved on both ends of the roller 942, and the two limit plates 943 are clamped on both sides of the track 912.
[0054] In this embodiment, during the rotation of the shaft 493, the shaft 493 drives the screw 92 to rotate, so that the outer frame 931 can move along the outer wall of the screw 92. Since the screw 92 can also rotate forward and reverse, the outer frame 931 can move back and forth along the outer wall of the screw 92, and the other outer frame 931 slides back and forth on the outer wall of the guide rod 97. During the movement of the two support seats 93, the roller 942 can be driven to move through the connecting plate 941, so that the roller 942 slides on the inside of the track 912. When the roller 942 slides inside the track 912, the overall trapezoidal track 912 can drive the roller 942 to move in a trapezoidal trajectory. For details, please refer to Figure 4 , Figure 5 as well as Figure 6 The roller 942 slides to the left along the bottom of the track 912, so that the roller 942 drives the support seat 93 to move left through the connecting plate 941, and the inner plate 933 on the support seat 93 drives the push plate 96 to move left through the horizontal axis 95, so that the bottom end of the push plate 96 rubs against the bottom of the pyrolysis furnace 2, and the push plate 96 that moves to the left can push the biomass charcoal that is pyrolyzed from the pyrolysis furnace 2 to the bottom of the pyrolysis furnace 2, so that the biomass charcoal at the bottom of the pyrolysis furnace 2 can enter the decomposition furnace 1 through the feeding frame 21, and be fed into the decomposition furnace 1 for use as fuel, thereby reducing the use of coal powder, reducing the generation of nitrogen oxides, reducing the use of reducing agents, and saving the production cost of the enterprise. As the support seat 93 moves to the left, the roller 942 can push the baffle 915 on the inner side of the track 912, causing the baffle 915 to flip upward in the clockwise direction until the roller 942 moves to the leftmost end of the bottom of the track 912. The baffle 915 loses the squeezing of the roller 942 and flips counterclockwise under the action of gravity. In actual applications, a torsion spring can also be set between the baffle 915 and the built-in block 913 to provide an elastic force for the baffle 915 to flip and reset counterclockwise.
[0055] In this embodiment, when the roller 942 moves to the leftmost end of the bottom of the track 912, the screw 92 starts to reverse, prompting the support seat 93 to drive the roller 942 to start moving right through the connecting plate 941. When the roller 942 moves to the baffle 915, it is blocked and limited by the baffle 915, so that the roller 942 can move obliquely upward during the right movement, that is, move along the upper side of the track 912. At this time, as the roller 942 moves upward, the inner plate 933 can move inside the outer frame 931. Slide upward to stretch the support spring 934. When the inner plate 933 moves upward, the push plate 96 can be driven to move upward through the horizontal axis 95, so that when the push plate 96 moves to the right, its bottom end is away from the bottom of the pyrolysis furnace 2, thereby effectively preventing the push plate 96 that moves to the right from pushing and shoveling the biomass charcoal remaining at the bottom of the pyrolysis furnace 2 or the newly formed biomass charcoal that falls from the combustion area inside the pyrolysis furnace 2 to the bottom of the pyrolysis furnace 2 during the push plate 96 moving to the left, so that the biomass charcoal at the bottom of the pyrolysis furnace 2 cannot be fully transported to the inside of the decomposition furnace 1. Example
[0056] See also Figure 1 , Figure 8 , Fig. 9 as well as Fig.10 A feeding mechanism 5 is connected between the transmission mechanism 4 and the feeding cylinder 7. The transmission mechanism 4 can drive the pushing mechanism 9 and synchronously drive the feeding mechanism 5.
[0057] Specifically, the feeding mechanism 5 includes an auger 51 disposed inside the feeding cylinder 7 and extending to the inside of the hopper 8 . A rotating rod 52 is fixedly connected to the bottom end of the auger 51 . The rotating rod 52 rotates and penetrates the outer wall of the feeding cylinder 7 .
[0058] Furthermore, a fixing ring 53 is provided on the outer side of the bottom end of the rotating rod 52, and the fixing ring 53 is coaxially fixed with the spur column 48. The inner wall of the fixing ring 53 is evenly provided with ratchet grooves 54, and a plurality of ratchet pawls 56 matching with the ratchet grooves 54 are evenly provided on the outer side of the bottom end of the rotating rod 52. The ratchet 56 is rotatably connected to the rotating rod 52 through a rotating shaft, and a reset spring 55 is connected between the ratchet 56 and the rotating rod 52.
[0059] In this embodiment, each time the biochar is pushed, the spur column 48 can rotate forward and backward once, and when the spur column 48 rotates forward and backward, it can drive the fixing ring 53 to rotate forward and backward. Please refer to Fig. 9 and Fig.10During the counterclockwise rotation of the fixing ring 53, the ratchet groove 54 on the inner wall of the fixing ring 53 conflicts with the ratchet 56, and the ratchet 56 is limited by the outer wall of the rotating rod 52 and cannot rotate, so that during the counterclockwise rotation of the fixing ring 53, the rotating rod 52 can be driven to rotate by the ratchet 56, and the rotating rod 52 drives the auger 51 to rotate, so that the biomass fragments accumulated on the inner side of the hopper 8 can be transported to the feeding cylinder 7 by the auger 51, and put into the pyrolysis furnace 2 for pyrolysis, and the quantitative feeding work is automatically completed. And when the fixing ring 53 rotates clockwise, the ratchet groove 54 can push the ratchet 56, so that the ratchet 56 rotates clockwise through the rotating shaft, and will not drive the rotating rod 52 to rotate.
[0060] Working principle and use process: When working, turn on the power and start the motor 3. The motor 3 drives the active gear 47 to rotate through the output shaft. The active gear 47 drives the two transmission gears 46 to rotate synchronously. The two transmission gears 46 drive the rack 42 to transmit. The rack 42 can push the spur column 48 and can slide relative to the spur column 48, so that the spur column 48 can rotate alternately forward and reverse. Since the large bevel gear 491 and the fixed ring 53 are coaxially fixed with the spur column 48, during the rotation of the spur column 48, the fixed ring 53 and the large bevel gear 491 can be driven to rotate synchronously. In the process of large bevel gear 491 rotating alternately with spur column 48, small bevel gear 492 can be driven to rotate, and small bevel gear 492 can rotate several circles for every rotation of large bevel gear 491. In the process of small bevel gear 492 rotating, shaft rod 493 can be driven to rotate, shaft rod 493 drives screw rod 92 to rotate, so that outer frame 931 can move along the outer wall of screw rod 92. Since screw rod 92 can also rotate forward and reverse, outer frame 931 can move back and forth along the outer wall of screw rod 92, and the other outer frame 931 slides back and forth on the outer wall of guide rod 97.
[0061] During the movement of the two support seats 93, the connecting plate 941 can drive the roller 942 to move, so that the roller 942 slides inside the track 912. When the roller 942 slides inside the track 912, the overall trapezoidal track 912 can drive the roller 942 to move in a trapezoidal track. Figure 4 , Figure 5 as well as Figure 6The roller 942 slides to the left along the bottom of the track 912, so that the roller 942 drives the support seat 93 to move left through the connecting plate 941, and the inner plate 933 on the support seat 93 drives the push plate 96 to move left through the horizontal axis 95, so that the bottom end of the push plate 96 rubs against the bottom of the pyrolysis furnace 2, and the push plate 96 that moves to the left can push the biomass charcoal that is pyrolyzed from the pyrolysis furnace 2 to the bottom of the pyrolysis furnace 2, so that the biomass charcoal at the bottom of the pyrolysis furnace 2 can enter the decomposition furnace 1 through the feeding frame 21, and be fed into the decomposition furnace 1 for use as fuel, thereby reducing the use of coal powder, reducing the generation of nitrogen oxides, reducing the use of reducing agents, and saving the production cost of the enterprise. As the support seat 93 moves to the left, the roller 942 can push the baffle 915 on the inner side of the track 912, causing the baffle 915 to flip upward in the clockwise direction until the roller 942 moves to the leftmost end of the bottom of the track 912. The baffle 915 loses the squeezing of the roller 942 and flips counterclockwise under the action of gravity. In actual applications, a torsion spring can also be set between the baffle 915 and the built-in block 913 to provide an elastic force for the baffle 915 to flip and reset counterclockwise.
[0062] When roller 942 moves to the leftmost end of the bottom of track 912, screw rod 92 starts to reverse, prompting support seat 93 to drive roller 942 to start moving right through connecting plate 941. When roller 942 moves to baffle 915, it is blocked and limited by baffle 915, so that roller 942 can move obliquely upward during the right movement, that is, move along the upper side of track 912. At this time, as roller 942 moves upward, inner plate 933 can slide upward inside outer frame 931 , stretching the support spring 934, when the inner plate 933 moves upward, the push plate 96 can be driven to move upward through the horizontal axis 95, so that when the push plate 96 moves to the right, its bottom end is away from the bottom of the pyrolysis furnace 2, thereby effectively preventing the push plate 96 that moves to the right from pushing and shoveling the biomass charcoal remaining at the bottom of the pyrolysis furnace 2 or the newly formed biomass charcoal that falls from the combustion area inside the pyrolysis furnace 2 to the bottom of the pyrolysis furnace 2 during the leftward movement of the push plate 96, so that the biomass charcoal at the bottom of the pyrolysis furnace 2 cannot be fully transported to the inside of the decomposition furnace 1.
[0063] Each time the biochar is pushed, the spur column 48 can rotate forward and backward once, and when the spur column 48 rotates forward and backward, it can drive the fixing ring 53 to rotate forward and backward. Please refer to Fig. 9 and Fig.10During the counterclockwise rotation of the fixed ring 53, the ratchet groove 54 on the inner wall of the fixed ring 53 conflicts with the pawl 56, and the pawl 56 is limited by the outer wall of the rotating rod 52 and cannot rotate, so that during the counterclockwise rotation of the fixed ring 53, the rotating rod 52 can be driven to rotate by the ratchet 56, and the rotating rod 52 drives the auger 51 to rotate, so that the biomass fragments accumulated on the inner side of the hopper 8 can be transported to the feeding cylinder 7 by the auger 51, and put into the pyrolysis furnace 2 for pyrolysis, and the quantitative feeding work is automatically completed. And when the fixed ring 53 rotates clockwise, the ratchet groove 54 can push the pawl 56, so that the pawl 56 rotates clockwise through the rotating shaft, and will not drive the rotating rod 52 to rotate, that is, every time the push plate 96 reciprocates to push the biomass charcoal, the auger 51 can perform a rotation feeding work, with a high degree of automation and high use value.

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.
