Description

Technical Field

[0001] The present invention relates to the technical field of denitration catalysts, and in particular to an SCR denitration catalyst production device. Background Art

[0002] SCR (Selective Catalytic Reduction) honeycomb denitrification catalyst is an important environmental protection technology product used for flue gas denitrification in coal-fired power plants. It reduces nitrogen oxides (NOx) in flue gas into nitrogen and water through catalysis, thereby reducing air pollution. The main production steps of SCR denitrification honeycomb denitrification catalyst are: the main raw materials of titanium dioxide, ammonium metatungstate, and ammonium metavanadate are stirred with auxiliary materials such as glass fiber and clay to mix them evenly, and then formed into honeycomb rectangular blocks with the required pore size through extrusion molding equipment. The blocks are dried and calcined, and then cut into honeycomb catalyst monomers of a certain length and assembled into modules.

[0003] Among them, the quality of the inner pores of the catalyst directly affects the efficiency of the contact between the flue gas and the catalyst. In the existing technology, during the calcination heat treatment of the honeycomb denitrification catalyst, it is more important to control the temperature in the calcination chamber. However, since the honeycomb denitrification catalyst has more inner pores, the heat treatment of the honeycomb pores of many denitrification catalysts is different, resulting in a decrease in the molding quality of the inner wall of the honeycomb pores and a decrease in the working performance of the catalyst.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] See also Figures 1 to 7 , an embodiment of the present invention provides a technical solution:

[0031] An SCR denitration catalyst production device, comprising:

[0032] A continuous calcination space is provided, in which a substrate 1 is operated, and a variable tray is designed on the substrate 1, which can carry a honeycomb-shaped rectangular calcination object; an assembly frame 3 is slidably assembled on the substrate 1, and the assembly frame 3 can be displaced toward the honeycomb end of the calcination object; a plurality of guide tubes 4 corresponding to the honeycomb inner holes of the calcination object are rotatably designed on the assembly frame 3, and the outer wall of the guide tube 4 is designed with a plurality of air holes 5, and both ends of the guide tube 4 are open; a switching mechanism with two modes of convection and rotary spraying is provided, in which, in the convection mode, the air holes 5 are closed, and the guide tube 4 can output convective hot air to the honeycomb inner hole; in the rotary spraying mode, the insertion end of the guide tube 4 is closed, and the guide tube 4 can be displaced into the honeycomb inner hole, and the guide tube 4 can rotate and open the air holes 5 to output hot air with a calcination atmosphere into the honeycomb inner hole; a pump source for inputting hot air or calcination atmosphere into the guide tube 4; an integrated driver for controlling the displacement of the assembly frame 3.

[0033] In the accompanying drawings, Figures 1 to 7 The total number of flow tube arrays is not fully shown.

[0034] In the prior art, when the honeycomb SCR denitrification catalyst is subjected to calcination heat treatment, if the extrusion molding quality of the inner hole is defective, it will cause uneven heating of the inner hole, and excessive calcination will reduce the quality of the calcined object. In the present invention, by designing two usage modes of the guide tube 4, it can be switched in the calcination space, wherein the convection mode can be used to flow hot air or high-temperature gas so that it can accurately pass through the honeycomb inner hole of the calcined object, so that the high-temperature gas can form convection in the honeycomb inner hole, complete the heat treatment of the inner hole with high quality, and reduce the uneven heating. Secondly, it can also be switched to the rotary spray mode. In the process of heat treatment of the calcined object, it is also necessary to add a calcination atmosphere to the high-temperature gas. For example, studies have shown that the ferric oxide / LA catalyst calcined in an air atmosphere Compared with the catalyst calcined under argon atmosphere, it has better denitrification activity at low temperature, especially at 120-200°C, the denitrification efficiency can reach 80%-100%. Therefore, when the preset temperature is reached, a calcination atmosphere needs to be added. The flowing atmosphere helps to avoid overheating in local areas and reduce damage to the catalyst structure or performance degradation caused by uneven temperature. The flow of the calcination atmosphere can help achieve more uniform heating and ensure that all parts of the catalyst can reach consistent temperature conditions during the calcination process. The present invention can add calcination atmosphere to the high-temperature gas by designing a rotary spray mode, and at the same time utilize the rotation of the guide tube 4 to release the calcination atmosphere into the inner hole of the calcination object, so that the calcination atmosphere quickly enters the honeycomb inner hole and flows in parallel, thereby better controlling the calcination process and improving the calcination quality of the calcination object.

[0035] The substrate 1 can be moved in the calcining space, and the moving speed or residence time can be adjusted to ensure the calcining time and the transfer of the calcined object.

[0036] Among the more preferred embodiments, the switching mechanism includes a turbofan blade 6 fixedly installed inside the guide tube 4. When the pump source inputs hot air into the guide tube 4, the turbofan blade 6 will drive the guide tube 4 to rotate. A friction unit for limiting the rotation of multiple guide tubes 4 is installed on the assembly frame 3. The base plate 1 is also designed with a latch unit for sealing the insertion end of the guide tube 4. An adaptive switching valve is installed on the inner wall of the air hole 5. In the convection mode, the air hole 5 is closed, and in the rotary spray mode, the air hole 5 is open.

[0037] See also Figure 5 and Figure 6 In this embodiment, the pump source will input high-temperature gas into the guide tube 4, or the pump source can extract the high-temperature gas in the calcination space and output it to the inside of the guide tube 4. After the high-temperature gas enters the inside of the guide tube 4, due to the rotational assembly relationship between the guide tube 4 and the assembly frame 3, when the high-temperature airflow passes through the turbofan blades 6, the guide tube 4 can rotate, so that the high-temperature gas mixed with the calcination atmosphere can quickly fill the inner hole, thereby improving the calcination quality of the inner hole. In the convection mode, the insertion end of the guide tube 4 is open, and the air hole 5 will be closed, so that the high-temperature gas input from one end of the guide tube 4 can be output from the insertion end, guiding and aligning the high-temperature gas, so that the high-temperature gas can enter the honeycomb inner hole of the calcination object.

[0038] Example 2

[0039] Based on Example 1, this Example 2 provides a specific preferred embodiment, specifically:

[0040] The latch unit includes a vertical plate 20 slidably mounted on the base plate 1. A plurality of docking pins 21 corresponding to the guide tube 4 are rotatably mounted on the outer wall of the vertical plate 20. The insertion end of the guide tube 4 can form a rotational seal with the docking pins 21 after passing through the honeycomb inner hole of the calcined object. Figure 1 In this embodiment, by designing the fit between the docking pin 21 and the insertion end of the guide tube 4, the end of the guide tube 4 can be closed. At this time, the pressure of the high-temperature gas input into the guide tube 4 will increase, and the high-temperature gas will be ejected outward through the pores 5, so that the calcination atmosphere directly enters the honeycomb inner pores of the calcination object, thereby improving the calcination quality of the honeycomb inner pores of the calcination object.

[0041] In a more preferred embodiment, the switch valve includes two valve plates 23 rotatably mounted on the inner wall of the air hole 5. When the ends of the two valve plates 23 are in contact with each other, the flow of the air hole 5 can be blocked. A baffle 24 is installed on the inner wall of the air hole 5. The baffle 24 can limit the two valve plates 23 from deflecting downward into the guide tube 4. When the two valve plates 23 collide with the baffle 24, the baffle 24 limits the two valve plates 23 to a contact state to close the air hole 5. Please refer to Figure 3 In this embodiment, when both ends of the flow guide tube 4 are open, high-temperature gas is input into one end and the gas is output from the other end. The opening of the flow guide tube 4 is much larger than the opening of the air hole 5, so that the high-temperature gas can be output more smoothly to the insertion end of the flow guide tube 4. According to Bernoulli's principle, the pressure in the area where the fluid flows quickly will decrease, so that the air pressure in the calcination space will cause the two valve plates 23 to deflect toward the inside of the flow guide tube 4, and then keep in contact under the restriction of the baffle 24 to close the air hole 5, thereby realizing the output of high-temperature gas. When switching to the rotary spray mode, the insertion end of the flow guide tube 4 is blocked. At this time, the gas pressure inside the flow guide tube 4 will increase, and the gas pressure in the calcination space is lower than the gas pressure inside the flow guide tube 4, which will cause the two valve plates 23 to deflect outward, release the blockage of the air hole 5, and allow the airflow inside the flow guide tube 4 to be output outward.

[0042] Example 3

[0043] Based on Example 1 and Example 2, this Example 3 provides a specific preferred embodiment, specifically:

[0044] The friction unit includes a plurality of rotating shafts rotatably mounted on the assembly frame 3, and a plurality of cams 9 are fixedly mounted on the outer wall of the rotating shaft. After the cams 9 rotate at a preset angle, they can press and limit the outer wall of the guide tube 4. The multiple guide tubes 4 are in a rectangular array, and the multiple cams 9 are respectively located between the rows and columns. The assembly frame 3 is designed with a transmission component for controlling the synchronous rotation of the multiple rotating shafts. In the convection state, the cams 9 will press the outer wall of the guide tube 4, thereby locking the guide tube 4 by friction. When switching to the rotary spray mode, the cams 9 release the lock on the guide tube 4, so that the guide tube 4 can rotate with the cooperation of the turbofan blades 6, thereby effectively inputting the calcining atmosphere into the honeycomb inner hole. The continuous input of the calcining atmosphere can increase the pressure of the honeycomb inner hole and cause the calcining atmosphere to flow. Alternatively, after the calcining atmosphere is input into the honeycomb inner hole, it can exit the guide tube 4 and use the convection mode to make the calcining atmosphere flow, so as to improve the calcination quality of the honeycomb inner hole.

[0045] Furthermore, the transmission component includes an assembly base 2 fixedly mounted on the assembly frame 3, a worm 18 is rotatably mounted on the assembly base 2, a worm gear 17 is fixedly mounted on the outer wall of the rotating shaft passing through the assembly frame 3, multiple worm gears 17 are meshed with the worm 18 for transmission, and a high-temperature motor is installed in the assembly base 2 to control the rotation of the worm 18. Figure 2 By utilizing the cooperation of the worm 18 and the multiple worm wheels 17, the multiple cams 9 can be controlled synchronously and unlocked or locked synchronously.

[0046] Example 4

[0047] Based on Examples 1 to 3, this Example 4 provides a specific preferred embodiment, specifically:

[0048] The variable tray includes a plurality of first bearing rollers 11 and a plurality of second bearing rollers 12, which are alternately distributed. The bottoms of the plurality of first bearing rollers 11 and the second bearing rollers 12 are fixedly mounted with a frame 14. A lifter is designed on the base plate 1, and the lifter can control any frame 14 to move downward. Figure 1 and Figure 4 In this embodiment, the first supporting roller 11 and the second supporting roller 12 constitute the supporting chassis of the variable pallet. When one of the frames 14 is displaced downward, the downward displacement of the first supporting roller 11 or the second supporting roller 12 can be controlled, thereby freeing part of the bonding part of the calcining object, so that the part can also come into contact with the high-temperature gas or calcining atmosphere without affecting the stability of the variable pallet. The lifter can operate at high temperature and only needs to control the downward movement and reset of the frame 14. The calcination quality of the outer surface will affect the thermal stability and durability of the calcination object. Therefore, it is necessary to improve whether the outer surface has different calcination heat treatment to avoid poor calcination quality of the bearing bonding part and reduce bad points.

[0049] Example 5

[0050] Based on Examples 1 to 4, this Example 5 provides a specific preferred embodiment, specifically:

[0051] Two ribs 13 are fixedly installed on the top of the first supporting roller 11 and the second supporting roller 12. The outer walls of the opposite surfaces of the two ribs 13 are provided with multiple notches, and the multiple notches are equidistantly distributed along the axial direction of the ribs 13. By designing the ribs 13, the bearing stability of the calcination object can be improved, and when the first supporting roller 11 or the second supporting roller 12 is displaced downward, the position of the notch will also change, thereby improving the calcination quality of the side of the calcination object.

[0052] Furthermore, the SCR denitration catalyst production device also includes multiple calcining furnaces 15, the calcining space is set inside the calcining furnace 15, the multiple calcining furnaces 15 are arranged continuously, and the multiple calcining spaces are sequentially associated, and the temperature inside the multiple calcining furnaces 15 can be freely set.

[0053] Furthermore, the pump source is arranged outside the calcining furnace 15, and the output end of the pump source is connected to a plurality of collecting pipes 8, and the collecting pipes 8 are fixedly connected to the packaging pipes 7, and the packaging pipes 7 are rotatably connected to the input end of the guide pipe 4, see Figure 2 The pump source can synchronously input high-temperature gas to multiple collecting pipes 8, and the multiple collecting pipes 8 use the intermediary relationship of the packaging pipe 7 to transfer the high-temperature gas to the guide pipe 4.

[0054] By utilizing the above-mentioned structures, the high-temperature gas can accurately pass through the honeycomb inner holes of the calcination object, so that the high-temperature gas can form convection in the honeycomb inner holes, reducing the uneven heating situation. It can also spin-spray the high-temperature gas containing the calcination atmosphere to improve the calcination quality of the honeycomb inner holes.

[0055] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
