Description

Technical Field

[0001] The invention belongs to the technical field of organic solid waste treatment, and in particular relates to a device and method for pyrolysis treatment of organic solid waste. Background Art

[0002] The small scale of treatment limits its application in large-scale waste treatment. The design capacity of many devices cannot meet the large-scale waste treatment needs of cities or industrial parks, resulting in waste accumulation and possible environmental pollution. This scale limitation often stems from insufficient technology investment and inaccurate market demand assessment. Many small pyrolysis devices have failed to conduct sufficient market research, resulting in the inability to reasonably configure the equipment capacity. Secondly, many devices have too long reaction time during operation, and due to the limitations of reaction conditions, they fail to achieve efficient conversion of waste, resulting in some waste remaining, and the waste residue is easily carried with harmful smoke to pollute the environment when it is discharged. To solve the problem of low efficiency;

[0003] The conventional practice is to increase heating efficiency or improve atmosphere control by introducing catalysts, but such methods often have high technical requirements, increase the complexity of the equipment and maintenance costs, have a long construction period, and are difficult to achieve rapid improvements. In addition, there are many toxic smoke leakage problems after solid slag treatment, which is often caused by insufficient equipment sealing and poor design of the flue gas collection system, resulting in the harmful substances generated during the waste pyrolysis process not being effectively captured and directly discharged into the environment. In order to reduce smoke leakage, more complete flue gas purification devices and enhanced sealing measures are usually used, but this will significantly increase equipment investment and operating costs. At the same time, regular inspections and maintenance are still required during the production process to ensure its long-term effectiveness, which requires additional manpower and material costs. Therefore, we hope to design an organic solid waste pyrolysis treatment device with a new structure to solve this problem. Summary of the invention

[0023] The present invention also relates to a method for pyrolysis treatment of organic solid waste, comprising the following steps:

[0024] a. At the beginning of the equipment startup, it is necessary to check the switch parts of the equipment to ensure that the butterfly valve in the switch parts is in the closed state. When the butterfly valve is closed, the corresponding material blocking parts are also in the closed state. Then, the control box can be used to control the electric heating tubes 1, 2, 3 and 4 in the primary heat treatment component and the secondary heat treatment component to be energized. After the electric heating tubes 1, 2, 3 and 4 are energized, the pyrolysis chamber 1, 2, 3 and the inside of the heating element are heated (the heating temperature depends on the required treatment temperature). The type of organic solid waste is determined by the type of organic solid waste. After heating for a certain period of time, the feed piece and the drive module 2 are started through the control box. The drive module 2 drives the driven gear on the left side of the furnace body through the active gear, and rotates smoothly under the support and guidance of the support piece 1 and the support piece 2 on the left and right sides of the mounting frame. The rotation speed of the furnace body is set between 200 and 500 revolutions, and the organic solid waste to be pyrolyzed is transported to the hopper of the feed piece through the external feeding equipment. The power module drives the spiral blades in the conveying pipe to transport the organic solid waste falling from the hopper to the inside of the rotating furnace body.

[0025] b. After the organic solid waste enters the furnace body, the multiple electric heating tubes 4 on the upper and lower sides of the furnace body continue to heat the furnace body, so that the organic solid waste inside the rotating furnace body can be fully heated and pyrolyzed. With the continuous addition of subsequent organic solid waste, the previously entered organic solid waste is driven by the spiral blades to continuously move to the right end of the furnace body until it moves to the left side of the baffle of the material blocking member. At this time, the drive module 1 can be started through the control box to open the butterfly valve and synchronously rotate the material blocking member 180 degrees (in actual use, in the initial state, the notched part of the baffle faces upward, indicating blocking), which makes the notched part of the baffle face downward, and the organic solid waste that has been heated and pyrolyzed for the first time passes through the baffle. The notch on the lower side moves the material guide, and the material discharge barrel in the material guide and the connecting pipe and butterfly valve on the upper side of the switch assembly are transported to the upper side of the secondary heat treatment assembly. The opening conditions of the baffle and the butterfly valve are determined according to the organic solid waste to be treated. For organic solid waste that is easier to heat and pyrolyze, the baffle and the organic solid waste can be set to be normally open, and the rotation speed of the furnace body can be appropriately reduced. The rotation speed can be controlled between 350-500 revolutions. If it is difficult to heat and pyrolyze organic solid waste, the baffle and the butterfly valve can be opened for one to three minutes after the furnace body is heated for a certain period of time, so that the organic solid waste that has been heated can be discharged smoothly, and the rotation speed of the furnace body can be controlled between 200-350 revolutions;

[0026] c. After the first pyrolysis, the organic solid waste enters the pyrolysis chamber 1 through the material guide and the switch assembly, and falls on the transmission member 1 to the upper right side of the rotating transmission chain 1. The active shaft member 1 and the driven shaft member 1 on the transmission member 1 cooperate to drive the transmission chain 1 to rotate counterclockwise, and the electric heating tube 1 on the rear side of the pyrolysis chamber 1 continuously heats the inside of the pyrolysis chamber 1, so that the fully turned organic solid waste is heated again, and the smoke and dust gas after falling and turning is transported to the external waste gas treatment through the exhaust gas exhaust pipe 1 on the upper right side of the pyrolysis chamber 1. With the rotation of the transmission chain 1, the organic solid waste is continuously moved to the left and falls from the left end of the transmission chain 1 to the inside of the left end of the pyrolysis chamber 2, and smoothly falls on the left end of the transmission chain 2 on the transmission member 2. The active shaft member 2 and the driven shaft member 2 on the transmission member 2 cooperate to drive the transmission chain 2 to rotate clockwise, and the electric heating tube 2 on the rear side of the pyrolysis chamber 2 continuously heats the inside of the pyrolysis chamber 2;

[0027] d. As the conveyor chain 3 rotates, the organic solid waste is continuously moved to the right and falls from the left end of the conveyor chain 2 to the right end of the pyrolysis chamber 3, and smoothly falls on the right end of the conveyor chain 3 on the transmission member 3. The active shaft member 3 and the driven shaft member 3 on the transmission member 3 cooperate to drive the conveyor chain 3 to rotate counterclockwise, and the electric heating tube 3 on the rear side of the pyrolysis chamber 3 continuously heats the inside of the pyrolysis chamber 3, which makes the organic solid waste continuously heated and continuously pyrolyzed during continuous turning, and finally enters the waste residue box through the discharge port on the left side of the pyrolysis chamber 3 at the left end of the conveyor chain 3. The waste gas and smoke generated by the falling impact are transported to the external waste gas treatment equipment through the waste gas exhaust pipe 2 on the left side of the pyrolysis chamber 3 for unified environmental protection treatment. The rotation speeds of the above-mentioned transmission member 1, transmission member 2 and transmission member 3 are determined according to the organic solid waste to be treated. The rotation speed of the organic solid waste that is easier to heat and pyrolyze can be controlled between 400-600 revolutions. If the organic solid waste that is more difficult to heat and pyrolyze is encountered, it can be controlled between 200-400 revolutions.

[0028] After adopting the above technical scheme, the beneficial effects of the present invention are as follows: by setting a primary heat treatment component, the organic solid waste machine is fully heated and pyrolyzed in a relatively closed and rotatable furnace body, which helps to quickly increase the temperature of the organic solid waste being heated, thereby ensuring the heating and pyrolysis speed of the organic solid waste, and the organic solid waste can be continuously pyrolyzed in conjunction with the secondary heat treatment component, greatly improving the organic solid waste treatment capacity of the entire device;

[0029] The setting of the secondary heat treatment component can further heat and pyrolyze the organic solid waste, so as to avoid the organic solid waste from being retained in the furnace for too long, which will lead to a reduction in the equipment processing capacity. After continuous turning and tumbling, the pyrolysis efficiency of the organic solid waste can be effectively improved and the pyrolysis can be completely completed, so as to avoid residues. Moreover, the waste gas and smoke hidden in the waste residue can be stimulated to avoid the waste residue entering the waste residue box containing a large amount of waste gas and smoke, thereby reducing the difficulty of subsequent waste residue treatment, ensuring that the waste gas and smoke will not be excessively leaked, and improving the environmental protection performance of the equipment.

[0030] The material blocking piece matched with the switch assembly can flexibly change the time that organic solid waste stays in the furnace body according to its type, greatly improving the equipment's ability to flexibly process different organic solid wastes;

[0031] The configuration of the transmission member 1, the transmission member 2 and the transmission member 3 can help improve the effect and efficiency of the secondary pyrolysis of the organic solid waste, thereby enabling the organic solid waste to be completely pyrolyzed before being discharged;

[0032] Through the pyrolysis treatment method of organic solid waste, the corresponding rate matching can be carried out according to the different organic solid wastes to be treated, thereby maximizing the treatment efficiency and treatment effect, which helps to improve the treatment capacity of different organic solid wastes and expand the application scope of the equipment.

After the electric heating tube 1 343, the electric heating tube 2 354, the electric heating tube 3 364 and the electric heating tube 4 561 are energized, the pyrolysis chamber 1 330, the pyrolysis chamber 2 320, the pyrolysis chamber 3 310 and the heating element 560 are heated. After heating for a certain period of time, the control box 2 00Start the feed member 540 and the second drive module 530. The second drive module 530 drives the driven gear 552 on the left side of the furnace body 553 through the driving gear 531. Under the support and guidance of the first support member 520 and the second support member 590 on the left and right sides of the mounting frame 510, the drive module 530 smoothly rotates, and the organic solid waste to be pyrolyzed is transported to the hopper 543 of the feed member 540 through the external feeding equipment. The power module 542 drives the spiral blade 544 in the conveying pipe 541 to transport the organic solid waste falling from the hopper 543 to the inside of the rotating furnace body 553.

[0072] After the organic solid waste enters the furnace body 553, the multiple electric heating tubes 561 on the upper and lower sides of the furnace body 553 continue to heat the furnace body 553, so that the organic solid waste inside the rotating furnace body 553 can be fully heated and pyrolyzed. As the subsequent organic solid waste is continuously added, the organic solid waste previously entered is driven by the spiral blade 544 to continuously move to the right end of the furnace body 553 until it moves to the left side of the baffle 582 of the material blocking member 580. At this time, the drive module 1 can be started by the control box 200. 430 then opens the butterfly valve 420 and synchronously rotates the material blocking member 580 180 degrees (the butterfly valve 420 is closed, and the corresponding material blocking member 580 is also in a closed state), so that the notched portion of the baffle 582 faces downward, and the organic solid waste after the first heating and pyrolysis moves to the material guide member 570 through the notch on the lower side of the baffle 582, and is transported to the upper interior of the secondary heat treatment assembly 300 by the material discharge barrel 572 in the material guide member 570 and the connecting pipe 410 and the butterfly valve 420 on the upper side of the switch assembly 400;

[0073] By setting up the primary heat treatment component 500, the organic solid waste is fully heated and pyrolyzed in a relatively closed and rotatable furnace body 553, which helps to quickly increase the temperature of the organic solid waste, thereby ensuring the heating and pyrolysis speed of the organic solid waste.

[0081] As a second embodiment of the present invention, based on the above-mentioned first embodiment, when the organic solid waste after the first pyrolysis enters the interior of the pyrolysis chamber 330 through the material guide 570 and the switch assembly 400, it falls on the transmission member 340 and the upper right side of the rotating transmission chain 342. The driving shaft 344 and the driven shaft 341 on the transmission member 340 cooperate to drive the transmission chain 342 to rotate counterclockwise, and the electric heating tube 343 on the rear side of the pyrolysis chamber 330 continuously heats the interior of the pyrolysis chamber 331, so that the fully turned organic solid waste is heated again, and the lower The flue gas after the fall and flip is transported to the external waste gas treatment through the waste gas exhaust pipe 1 on the upper right side of the pyrolysis chamber 1 330. As the conveying chain 1 342 rotates, the organic solid waste is continuously moved to the left and falls from the left end of the conveying chain 1 342 to the inside of the left end of the pyrolysis chamber 2 320, and smoothly falls on the left end of the conveying chain 2 352 on the conveying member 2 350.

[0082] As the conveyor chain 362 rotates, the organic solid waste is continuously moved to the right and falls from the left end of the conveyor chain 2 352 to the inside of the right end of the pyrolysis chamber 3 310, and smoothly falls on the right end of the conveyor chain 3 362 on the transmission member 3 360.

[0083] The setting of the secondary heat treatment component 300 can further heat and pyrolyze the organic solid waste, so as to avoid the organic solid waste from being retained in the furnace body 553 for too long, which may reduce the processing capacity of the equipment. After continuous turning and tumbling, the pyrolysis efficiency of the organic solid waste can be effectively improved and the pyrolysis can be completely completed, so as to avoid residues. Moreover, the waste gas and smoke hidden in the waste residue can be stimulated to avoid the waste residue entering the waste residue box 370 containing a large amount of waste gas and smoke, thereby reducing the difficulty of subsequent waste residue processing, ensuring that the waste gas and smoke will not be excessively leaked, and improving the environmental protection performance of the equipment.

[0084] The provision of the transmission member 1 340 , the transmission member 2 350 , and the transmission member 3 360 can help to improve the effect and efficiency of the secondary pyrolysis of the organic solid waste, thereby enabling the organic solid waste to be completely pyrolyzed before being discharged.

[0085] The present invention also relates to a method for pyrolysis treatment of organic solid waste, comprising the following steps:

[0086] At the beginning of the start-up of the equipment, it is necessary to check the switch of the equipment first to ensure that the butterfly valve 420 in the switch is in the closed state. When the butterfly valve 420 is closed, the corresponding material blocking member 580 is also in the closed state. Then, the control box 200 can be used to control the electric heating tube 1 343, the electric heating tube 2 354, the electric heating tube 3 364 and the electric heating tube 4 561 in the primary heat treatment component 500 and the secondary heat treatment component 300 to be energized. After the electric heating tube 1 343, the electric heating tube 2 354, the electric heating tube 3 364 and the electric heating tube 4 561 are energized, the pyrolysis chamber 1 330, the pyrolysis chamber 2 320, the pyrolysis chamber 3 310 and the inside of the heating element 560 are heated (the heating temperature depends on the required treatment). The feeder 540 and the drive module 2 530 are started through the control box 200 after heating for a certain period of time. The drive module 2 530 drives the driven gear 552 on the left side of the furnace body 553 through the driving gear 531, and the furnace body 553 rotates smoothly under the support and guidance of the support member 1 520 and the support member 2 590 on the left and right sides of the mounting frame 510. The rotation speed of the furnace body 553 is set between 200 and 500 revolutions, and the organic solid waste to be pyrolyzed is transported to the hopper 543 of the feeder 540 through the external feeding equipment. The power module 542 drives the spiral blade 544 in the conveying pipe 541 to transport the organic solid waste falling from the hopper 543 to the inside of the rotating furnace body 553;

[0087] After the organic solid waste enters the furnace body 553, the multiple electric heating tubes 561 on the upper and lower sides of the furnace body 553 continue to heat the furnace body 553, so that the organic solid waste inside the rotating furnace body 553 can be fully heated and pyrolyzed. With the continuous addition of subsequent organic solid waste, the previously entered organic solid waste is driven by the spiral blade 544 to continuously move toward the right end of the furnace body 553 until it moves to the left side of the baffle 582 of the material blocking member 580. At this time, the drive module 430 can be started by the control box 200 to open the butterfly valve 420 and synchronously rotate the material blocking member 580 180 degrees, so that the notched part of the baffle 582 faces downward, and the organic solid waste that has been heated and pyrolyzed for the first time moves to the guide member 570 through the notch on the lower side of the baffle 582. The material discharge barrel 572 in the material guide 570 and the connecting pipe 410 and the butterfly valve 420 on the upper side of the switch assembly 400 are transported to the upper side of the secondary heat treatment assembly 300. The opening conditions of the baffle 582 and the butterfly valve 420 are determined according to the organic solid waste to be treated. For organic solid waste that is easier to heat and pyrolyze, the baffle 582 and the organic solid waste can be set to be normally open, and the rotation speed of the furnace body 553 can be appropriately reduced, and the rotation speed can be controlled between 350-500 revolutions. If the organic solid waste is difficult to heat and pyrolyze, the baffle 582 and the butterfly valve 420 can be opened for one to three minutes after the furnace body 553 is heated for a certain period of time, so that the organic solid waste that has been heated can be discharged smoothly, and the rotation speed of the furnace body 553 can be controlled between 200-350 revolutions;

[0088] After the first pyrolysis, the organic solid waste enters the pyrolysis chamber 330 through the guide member 570 and the switch assembly 400, and falls on the transmission member 340 to rotate the upper right side of the transmission chain 342. The driving shaft 344 on the transmission member 340 cooperates with the driven shaft 341 to drive the transmission chain 342 to rotate counterclockwise. The electric heating tube 343 on the rear side of the pyrolysis chamber 330 continues to heat the inside of the pyrolysis chamber 331, so that the fully turned organic solid waste is heated again, and the smoke gas after falling and turning passes through the heat. The waste gas exhaust pipe 1 on the upper right side of the pyrolysis chamber 1 330 is transported to the outside for waste gas treatment. As the conveying chain 1 342 rotates, the organic solid waste is continuously moved to the left and falls from the left end of the conveying chain 1 342 to the inside of the left end of the pyrolysis chamber 2 320, and smoothly falls on the left end of the conveying chain 2 352 on the transmission member 2 350. The driving shaft member 2 351 and the driven shaft member 2 353 on the transmission member 2 350 cooperate to drive the conveying chain 2 352 to rotate clockwise, and the electric heating pipe 2 354 on the rear side of the pyrolysis chamber 2 320 continuously heats the inside of the pyrolysis chamber 2 321;

[0089] As the conveyor chain 362 rotates, the organic solid waste is continuously moved to the right and falls from the left end of the conveyor chain 2 352 to the right end of the pyrolysis chamber 3 310, and smoothly falls on the right end of the conveyor chain 3 362 on the transmission member 360. The active shaft member 363 and the driven shaft member 361 on the transmission member 360 cooperate to drive the conveyor chain 3 362 to rotate counterclockwise, and the electric heating tube 364 on the rear side of the pyrolysis chamber 3 310 continuously heats the inside of the pyrolysis chamber 3 313, so that the organic solid waste is continuously heated and continuously pyrolyzed during continuous flipping, and finally on the left side of the conveyor chain 3 362 The exhaust gas and smoke generated by the falling impact are transported to the external exhaust gas treatment equipment through the exhaust gas exhaust pipe 2 on the left side of the pyrolysis chamber 310 for unified environmental protection treatment. The rotation speed of the above-mentioned transmission component 1 340, transmission component 2 350 and transmission component 3 360 is determined according to the organic solid waste to be treated. For organic solid waste that is easier to heat and pyrolyze, the rotation speed can be controlled between 400-600 rpm. If it is difficult to heat and pyrolyze organic solid waste, the rotation speed can be controlled between 200-400 rpm.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

8. A method for pyrolysis treatment of organic solid waste according to any one of claims 1 to 7, characterized in that: The steps include: a. When the equipment is started, it is necessary to first check the switch components of the equipment to ensure that the butterfly valve (420) in the switch components is in a closed state. When the butterfly valve (420) is closed, the corresponding material blocking component (580) is also in a closed state. Then, the control box (200) can be used to control the electric heating tube 1 (343), the electric heating tube 2 (354), the electric heating tube 3 (364) and the electric heating tube 4 (561) in the primary heat treatment component (500) and the secondary heat treatment component (300) to be energized. After the electric heating tube 1 (343), the electric heating tube 2 (354), the electric heating tube 3 (364) and the electric heating tube 4 (561) are energized, the pyrolysis chamber 1 (330), the pyrolysis chamber 2 (320), the pyrolysis chamber 3 (310) and the heating component (560) are heated. After heating for a certain period of time, the feed member (540) and the second drive module (530) are started through the control box (200). The second drive module (530) drives the driven gear (552) on the left side of the furnace body (553) through the driving gear (531). The driven gear (552) on the left side of the furnace body (553) rotates smoothly under the support and guidance of the first support member (520) and the second support member (590) on the left and right sides of the mounting frame (510). The rotation speed of the furnace body (553) is set between 200 and 500 revolutions. The organic solid waste to be pyrolyzed is transported to the hopper (543) of the feed member (540) through an external feeding device. The power module (542) drives the spiral blade (544) in the conveying pipe (541) to transport the organic solid waste falling from the hopper (543) to the inside of the rotating furnace body (553). b. After the organic solid waste enters the furnace body (553), the plurality of electric heating tubes (561) on the upper and lower sides of the furnace body (553) continue to heat the furnace body (553), thereby enabling the organic solid waste inside the rotating furnace body (553) to be fully heated and pyrolyzed. As subsequent organic solid waste is continuously added, the previously entered organic solid waste is driven by the spiral blade (544) to continuously move toward the right end of the furnace body (553) until it moves to the left side of the baffle (582) of the material blocking member (580). At this time, the drive module (430) can be started through the control box (200) to open the butterfly valve (420) and synchronously rotate the material blocking member (580) 180 degrees, so that the notched portion of the baffle (582) faces downward, and the organic solid waste that has been heated and pyrolyzed for the first time passes through the notch on the lower side of the baffle (582) to the material guide member (570). The material is transported to the upper interior of the secondary heat treatment component (300) by the material discharge barrel (572) in the material guide member (570) and the connecting pipe (410) and the butterfly valve (420) on the upper side of the switch component (400). The opening conditions of the baffle (582) and the butterfly valve (420) are determined according to the organic solid waste to be treated. For organic solid waste that is easier to heat and pyrolyze, the baffle (582) and the organic solid waste can be set to be normally open, and the rotation speed of the furnace body (553) can be appropriately reduced, and the rotation speed can be controlled between 350 and 500 revolutions. If organic solid waste that is more difficult to heat and pyrolyze is encountered, the baffle (582) and the butterfly valve (420) can be opened for one to three minutes after the furnace body (553) has been heated for a certain period of time, so that the organic solid waste that has been heated can be discharged smoothly, and the rotation speed of the furnace body (553) can be controlled between 200 and 350 revolutions; c. After the first pyrolysis, the organic solid waste enters the pyrolysis chamber (330) through the material guide (570) and the switch assembly (400), and falls on the transmission member (340) to the upper right side of the rotating transmission chain (342). The driving shaft member (344) and the driven shaft member (341) on the transmission member (340) cooperate to drive the transmission chain (342) to rotate counterclockwise, and the electric heating tube (343) on the rear side of the pyrolysis chamber (330) continues to heat the inside of the pyrolysis chamber (331), so that the organic solid waste that has been fully turned over is heated again, and the smoke gas that has fallen and turned over passes through the heat. During the waste gas treatment that is transported to the outside by the waste gas exhaust pipe 1 on the upper right side of the pyrolysis chamber 1 (330), as the conveyor chain 1 (342) rotates, the organic solid waste is continuously moved to the left and falls from the left end of the conveyor chain 1 (342) to the inside of the left end of the pyrolysis chamber 2 (320), and smoothly falls on the left end of the conveyor chain 2 (352) on the transmission member 2 (350). The driving shaft member 2 (351) and the driven shaft member 2 (353) on the transmission member 2 (350) cooperate to drive the conveyor chain 2 (352) to rotate clockwise, and the electric heating pipe 2 (354) on the rear side of the pyrolysis chamber 2 (320) continuously heats the inside of the pyrolysis chamber 2 (321); d. As the conveyor chain 3 (362) rotates, the organic solid waste is continuously moved to the right and falls from the left end of the conveyor chain 2 (352) to the right end of the pyrolysis chamber 3 (310), and smoothly falls on the right end of the conveyor chain 3 (362) on the transmission member 3 (360). The driving shaft member 3 (363) and the driven shaft member 3 (361) on the transmission member 3 (360) cooperate to drive the conveyor chain 3 (362) to rotate counterclockwise. The electric heating tube 3 (364) on the rear side of the pyrolysis chamber 3 (310) continuously heats the inside of the pyrolysis chamber 3 (313), so that the organic solid waste is continuously heated and continuously pyrolyzed during the continuous turning, and finally on the conveyor chain 3 The left end of (362) enters into the waste slag box (370) through the discharge port (312) on the left side of the pyrolysis chamber three (310), and the waste gas and smoke generated by the falling impact are transported to the external waste gas treatment equipment through the waste gas exhaust pipe two on the left side of the pyrolysis chamber three (310) for unified environmental protection treatment. The rotation speed of the above-mentioned transmission component one (340), transmission component two (350) and transmission component three (360) is determined according to the organic solid waste to be treated. For organic solid waste that is easier to heat and pyrolyze, the rotation speed can be controlled between 400-600 rpm. If it is encountered that the organic solid waste is more difficult to heat and pyrolyze, it can be controlled between 200-400 rpm.
