DETAILED DESCRIPTION

[0030] The embodiment of the present application discloses a waste gas collection and utilization device for steam-cured aerated concrete blocks. Through the arrangement of an inner wall scraper 12, the pneumatic turbofan 8 can obtain power and generate rotation under the drive of the exhaust gas. The rotation of the pneumatic turbofan 8 drives the inner wall scraper 12 to move in contact with the inner wall of the main conveying cylinder 4, and scrape off the ash on the inner wall of the main conveying cylinder 4. After scraping, the ash becomes slag and falls to the outside of the slag sliding part 6011 and the slag guiding part 6012, so that the exhaust gas with waste heat is used to generate power for the inner wall scraper, thereby saving energy consumption.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Embodiment 1:

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7 The embodiment of the present application discloses a waste gas collection and utilization device for a steam-cured aerated concrete block, comprising: a waste gas inlet bin 1, a transition air duct 2, a waste slag collection shell bin 3 and a main conveying cylinder 4, wherein the waste gas inlet bin 1, the transition air duct 2, the waste slag collection shell bin 3 and the main conveying cylinder 4 are sequentially arranged from bottom to top, a slag guide channel 6, the slag guide channel 6 is fixedly arranged at the top of the transition air duct 2, the slag guide channel 6 is arranged on the inner side of the main conveying cylinder 4, and an anti-wall-adhering structure 11 is arranged on the outer side of the slag guide channel 6, and the anti-wall-adhering structure 11 is used to prevent the scraped ash from adhering to the slag guide channel On the outer wall of the road 6, there is an inner wall scraper 12, and the inner wall scraper 12 is arranged in contact with the inner wall of the main conveying cylinder 4. The anti-wall sticking structure 11 includes a bottom plate 1101, and side brackets 1102 are fixedly arranged on both sides of the bottom plate 1101. A transfer short column 1105 is penetrated and rotatably arranged on one side of the side bracket 1102. A wall scraper 1104 is fixedly arranged at one end of the transfer short column 1105 close to each other, and a reset torsion spring 1103 is fixedly arranged on the outer side of the transfer short column 1105, and the other end of the reset torsion spring 1103 is fixedly connected to the side bracket 1102.

[0034] The inner wall scraper 12 is arranged to fit the inner wall of the main conveying tube 4. The inner wall scraper 12 will scrape off the ash attached to the inner wall of the main conveying tube 4 during movement. The movement of the inner wall scraper 12 will drive the anti-sticking structure 11 to move. The ash enters the slag dropping chamber 3011 along the slag guiding channel 6. A small amount of ash will remain on the outside of the slag guiding channel 6. The wall scraper 1104 in the anti-sticking structure 11 fits the outer wall of the slag guiding channel 6 and moves, thereby scraping off the residual ash on its outer wall and entering the slag dropping chamber 3011. When the wall scraper 1104 and When the auxiliary shock-absorbing protrusion 5 contacts, the wall scraper 1104 will leave the slag guiding channel 6, and the reset torsion spring 1103 will shrink. After the wall scraper 1104 leaves the auxiliary shock-absorbing protrusion 5, the wall scraper 1104 will hit the slag guiding channel 6 through the elastic force of the reset torsion spring 1103, so that the slag guiding channel 6 will vibrate. When scraping off the ash outside the slag guiding channel 6, the ash will be vibrated down at the same time, thereby reducing the accumulation speed of the ash outside the slag guiding channel 6, facilitating cleaning, improving the recovery efficiency of the ash, and thus increasing the effective flow area of ​​the exhaust gas.

[0035] Among them, see Figure 2 , Figure 3 and Figure 4 A slag dropping chamber 3011 is arranged between the waste slag collecting shell bin 3 and the transition air duct 2, a slag sliding chamber 4011 is arranged between the outward slag cylinder 401 and the slag guiding channel 6, an air passage 4012 is arranged inside the main conveying cylinder 4, and the slag guiding channel 6 is divided into a slag sliding part 6011 and a slag guiding part 6012, both of which are trumpet-shaped, and the diameter of the slag sliding part 6011 is smaller than that of the slag guiding part 6012, and an auxiliary shock bulge 5 is fixedly arranged on the outer side of the slag sliding part 6011, and an anti-wall-adhering structure 11 is arranged in the slag sliding chamber 4011.

[0036] Among them, the inner wall scraper plate 12 will scrape off the ash attached to the inner wall of the main conveying cylinder 4 during movement, and form ash slag that falls on the sliding slag part 6011, and then the sliding slag part 6011 reaches the slag guiding part 6012. At this time, the ash slag is in the sliding slag chamber 4011, and then enters the slag falling chamber 3011 for collection, which is convenient for subsequent processing.

[0037] Specifically, an aerodynamic turbofan 8 is provided inside the transition air duct 2, and a transmission connecting column 801 is penetrated and fixedly provided on the top of the aerodynamic turbofan 8.

[0038] When the exhaust gas passes through the pneumatic turbofan 8, it will drive the pneumatic turbofan 8 to rotate, and the rotation of the pneumatic turbofan 8 will drive the transmission column 801 to rotate together, using the exhaust gas with residual heat to generate power to drive the cleaning component 10, the anti-wall structure 11 and the inner wall scraper 12, thereby saving energy consumption.

[0039] In this embodiment, see Figure 1 , Figure 2 and Figure 3 The transition air duct 2 is fixedly arranged at the top of the waste gas inlet bin 1, and a waste gas inlet port 101 is arranged at the bottom end of the waste gas inlet bin 1, and the waste gas inlet port 101 is externally connected to the autoclave.

[0040] The waste gas generated by curing concrete blocks in the autoclave enters the waste gas inlet bin 1 through the waste gas inlet port 101. The outwardly expanded slag barrel 401 is provided to adapt to the shape of the slag guiding channel 6 and is used for the falling and storage of ash slag.

[0041] See also Figure 1 and Figure 2 An external top plate 402 is fixedly provided on the outside of the transition air duct 2 and the main conveying cylinder 4, and a connecting fixed column 403 is fixedly provided between the external top plates 402. A closing top cover 404 is detachably provided on the top of the main conveying cylinder 4, and an outlet pipe 405 is fixedly provided on the top of the closing top cover 404. The outlet pipe 405 is externally connected to the desulfurization equipment. The closing top cover 404 is conically set, and the outer diameter of the slag sliding part 6011 is smaller than the inner diameter of the main conveying cylinder 4.

[0042] Among them, the external top plate 402 and the connecting fixed column 403 are used to connect and fix the waste gas inlet bin 1 and the main conveying cylinder 4, and the closing top cover 404 is used to reduce the flow rate of the waste gas, thereby increasing the residence time of the waste gas in the main conveying cylinder 4 and making full use of the waste gas. The outer diameter of the slag sliding part 6011 is smaller than the inner diameter of the main conveying cylinder 4, so that the ash can slide along the outer wall of the slag sliding part 6011 after cleaning, which is convenient for collecting the ash.

[0043] See also Figure 2 and Figure 7 A water-passing coil 7 is arranged inside the main conveying cylinder 4, and the water-passing coil 7 is arranged above the slag guiding channel 6. Both ends of the water-passing coil 7 penetrate the air outlet pipe 405, and the two ends of the water-passing coil 7 are respectively connected to the water supply equipment and the water storage equipment.

[0044] Cold water enters from one end of the water-passing coil 7, and the water is sent into the water-passing coil 7 by the water supply equipment. After the water is heated, it can be pumped out through the external water storage equipment, and then new cold water is sent in through the water supply equipment. The cycle is repeated, and the water can be continuously heated to give full play to the heat in the exhaust gas. The heated water can be supplied to the workers for living water or for heating.

[0045] Embodiment 2:

[0046] Reference Figure 2 , Figure 3 and Figure 5 A cleaning component 10 is arranged inside the exhaust gas entry bin 1, and the cleaning component 10 includes a connecting frame 1001, which is fixedly arranged on the outside of the other end of the transmission connecting column 801, and a fixed bevel gear 1002 is rotatably arranged on the bottom end of the connecting frame 1001, and a movable bevel gear 1003 is symmetrically meshed on the outside of the fixed bevel gear 1002, and a cleaning roller brush 1004 is fixedly arranged on one end of the movable bevel gear 1003, and the cleaning roller brush 1004 is rotatably arranged on both sides of the connecting frame 1001.

[0047] Among them, the rotation of the transmission column 801 will drive the connecting frame 1001 in the cleaning component 10 to rotate, and the rotation of the connecting frame 1001 will drive the two movable bevel gears 1003 to move around. Since the movable bevel gear 1003 is in a meshing state with the fixed bevel gear 1002, the movable bevel gear 1003 will rotate while moving around. The rotation of the movable bevel gear 1003 will drive the cleaning roller brush 1004 to rotate, and then the large particles of impurities at the bottom of the barrier mesh plate 9 can be swept down, so as to achieve the effect of preliminary filtration of the exhaust gas and improve the quality of exhaust gas emissions.

[0048] For further information, see Figure 2 and Figure 5 A blocking mesh plate 9 is arranged on the outer side of the cleaning roller brush 1004, and the blocking mesh plate 9 is fixedly arranged on the inner side of the transition air duct 2. The transmission connecting column 801 passes through and is rotatably arranged on the top of the blocking mesh plate 9. A fixed wheel connecting column 1005 is fixedly arranged on one end of the fixed bevel gear 1002, and a transverse fixed plate 1006 is fixedly arranged on the other end of the fixed wheel connecting column 1005. The transverse fixed plate 1006 is fixedly arranged on the inner side of the exhaust gas inlet 101. The connecting adapter frame 1001 is rotatably arranged on the bottom end of the blocking mesh plate 9, and the blocking mesh plate 9 is fixedly arranged on the inner side of the transition air duct 2.

[0049] The bristles on the outside of the cleaning roller brush 1004 are in contact with the barrier mesh plate 9. When the cleaning roller brush 1004 rotates, it can brush off the impurities accumulated at the bottom of the barrier mesh plate 9 to prevent the filter holes of the barrier mesh plate 9 from being blocked, and can prevent large particles of impurities from passing through the barrier mesh plate 9. The setting of the horizontal fixed plate 1006 is convenient for fixing the fixed wheel connecting column 1005, so that the fixed bevel gear 1002 can be stable and motionless during use.

[0050] Working principle: the exhaust gas inlet 101 is connected to the autoclave to facilitate the recovery of the exhaust gas, and the exhaust pipe 405 is externally connected to the desulfurization equipment to facilitate the subsequent treatment of the utilized exhaust gas. The exhaust gas enters from the exhaust gas inlet 101, passes through the barrier mesh plate 9 and the pneumatic turbofan 8 and enters the main conveying cylinder 4. When the exhaust gas passes through the barrier mesh plate 9, large particles of impurities will be blocked outside, which has the effect of preliminary filtration and is convenient for subsequent discharge. The pneumatic turbofan 8 is driven by the exhaust gas to rotate, providing power for the cleaning component 10, the anti-wall structure 11 and the inner wall scraper 12, saving energy consumption;

[0051] When the hot exhaust gas passes through the pneumatic turbofan 8, it will be rotated, and the rotation of the pneumatic turbofan 8 will drive the transmission column 801 to rotate. The rotation of the transmission column 801 can drive the cleaning component 10, the anti-wall structure 11, the inner wall scraper 12 and the connecting cross plate 1201 connected thereto to move around, wherein the inner wall scraper 12 is arranged to fit the inner wall of the main conveying cylinder 4, and the inner wall scraper 12 will scrape off the ash attached to the inner wall of the main conveying cylinder 4 during the movement, and form ash slag that falls on the sliding slag part 6011, and then the sliding slag part 6011 reaches the slag guiding part 6012, at this time, the ash slag is in the sliding slag chamber 4011, and then enters the slag falling chamber 3011 for collection, which is convenient for subsequent processing;

[0052] It should be noted that the outer diameter of the slag sliding portion 6011 is smaller than the inner diameter of the main conveying tube 4, and the slag sliding portion 6011 and the slag guiding portion 6012 are configured in a trumpet shape to prevent the ash from entering the slag guiding channel 6 and falling back into the autoclave;

[0053] Among them, the movement of the connecting cross plate 1201 drives the anti-wall-adhering structure 11 to move, and the ash enters the slag-falling chamber 3011 along the slag-guiding channel 6. A small amount of ash will remain on the outside of the slag-guiding channel 6. The wall-adhering scraper 1104 in the anti-wall-adhering structure 11 moves in accordance with the outer wall of the slag-guiding channel 6, thereby scraping off the residual ash on its outer wall and entering the slag-falling chamber 3011. When the wall-adhering scraper 1104 contacts the auxiliary shock-absorbing protrusion 5, the wall-adhering scraper 1104 will leave the slag-guiding channel 6, and the reset torsion spring 1103 will shrink. When the wall-adhering scraper 1104 leaves the auxiliary shock-absorbing protrusion 5, the wall-adhering scraper 1104 will knock the slag-guiding channel 6 through the elastic force of the reset torsion spring 1103, so that the slag-guiding channel 6 will vibrate. When scraping off the ash outside the slag-guiding channel 6, the ash will be vibrated down at the same time, thereby reducing the accumulation speed of the ash outside the slag-guiding channel 6, facilitating cleaning, and improving the recovery efficiency of the ash.

[0054] The rotation of the transmission connecting column 801 will drive the connecting adapter frame 1001 in the cleaning component 10 to rotate, and the rotation of the connecting adapter frame 1001 will drive the two movable bevel gears 1003 to move around. Since the movable bevel gear 1003 is in meshing state with the fixed bevel gear 1002, the movable bevel gear 1003 will rotate while moving around. The rotating movement of the movable bevel gear 1003 will drive the cleaning roller brush 1004 to rotate, thereby sweeping down the large particles of impurities at the bottom of the barrier mesh plate 9, achieving the effect of preliminary filtration of the exhaust gas and improving the quality of exhaust gas emission.

[0055] Among them, the fixed bevel gear 1002 will not rotate, and the fixed bevel gear 1002 will be fixed due to the arrangement of the fixed wheel connecting column 1005 and the horizontal fixed plate 1006, so that the movable bevel gear 1003 and the cleaning roller brush 1004 can perform circumferential and self-rotation movements;

[0056] The heat in the exhaust gas can heat the water inside the water-passing coil 7, and the heated water can be used for heating or domestic water. The water-passing coil 7 is spirally arranged so that the exhaust gas can fully contact the water-passing coil 7. It should be noted that since the closing top cover 404 is conically arranged, the exhaust gas discharge flow rate is reduced, so that the exhaust gas can stay longer in the main conveying cylinder 4, thereby making full use of the thermal energy resources in the exhaust gas and improving the utilization rate of the exhaust gas.

[0057] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
