The treatment and disposal of domestic waste is an important task to improve the quality of the living environment and is related to people's livelihood and well-being.

[0003] The waste pyrolysis process refers to the process in which waste undergoes pyrolysis reaction under oxygen-deficient or oxygen-free conditions to generate recyclable combustible gas, organic oil and solid pyrolytic carbon. Compared with waste incineration technology, waste pyrolysis has the advantages of good adaptability to raw material properties, no dioxin production, low investment and small land occupation, making it a waste treatment technology with great potential.

[0004] The rotary kiln reactor is a special gas-solid contact reactor that has been widely used in the fields of building materials and chemical industry, such as cement kilns, dryers, etc. In recent years, due to its advantages such as good raw material adaptability, material mixing characteristics and flexible adjustability, the rotary kiln is just suitable for the treatment of domestic waste with unstable raw material composition and shape, and is increasingly used in the field of domestic waste pyrolysis.

[0005] In the process of applying the rotary kiln reactor to the pyrolysis reaction of domestic waste, it was found that due to the generally high water content and complex composition of domestic waste, the waste raw materials entering the rotary kiln reactor will cause the parts with high water content to stick together during the tumbling process in the reactor, forming larger block materials, which greatly increases the heat and mass transfer resistance of the materials, affects the final product yield and composition, and even causes the outlet materials to wrap around the unreacted materials, greatly reducing the thermal efficiency of the system.

[0006] In summary, solving the problems of high moisture content and easy agglomeration of domestic waste raw materials is the key to improving the product yield and system thermal efficiency of the pyrolysis reaction process. Utility Model Content

[0037] Example 1

[0038] See also Figure 1-3 The present embodiment provides a rotary kiln garbage pyrolysis device coupled with a rapid dehydration device. As can be seen from the figure, it includes a garbage conveying device 1, a material lifting pipe 5, a rotary kiln reactor and a high-temperature gas conveying device; the material lifting pipe 5 is provided with a connecting port 16 for feeding, and the outlet 17 of the material lifting pipe 5 extends into the rotary kiln reactor. The rotary kiln reactor is connected to the high-temperature gas conveying device, and the high-temperature gas conveying device is connected to the inlet of the material lifting pipe 5; the high-temperature gas conveying device is used to convey high-temperature gas to the material lifting pipe, and the high-temperature gas dries the material in the material lifting pipe 5 and transports the material to the rotary kiln reactor through the outlet 17.

[0039] The garbage conveying device 1 is connected to the connection port 16 of the material lifting pipe 5, and the garbage conveying device 1 is used to convey garbage to the material lifting pipe 5.

[0040] In this embodiment, the garbage conveying device 1 is provided with a garbage feed port 2 , and the domestic garbage to be processed enters from the garbage feed port 2 and is conveyed by the garbage conveying device 1 to the material lifting pipe 5 .

[0041] The rotary kiln garbage pyrolysis equipment coupled with a rapid dehydration device provided in this embodiment adds a material lifting pipe 5 at the front end of the rotary kiln reactor. The high-temperature gas is transported to the material lifting pipe 5 through the high-temperature gas conveying device, and the high-temperature gas is used to pre-treat the garbage. Inside the material lifting pipe 5, the high-temperature gas flows at a high speed and mixes with the domestic garbage. In the turbulent airflow, the solid garbage is quickly heated, the water is quickly evaporated, and the agglomerated garbage is broken up, laying the foundation for fully and efficiently realizing the pyrolysis process of the garbage in the rotary kiln reactor.

[0042] Furthermore, inorganic materials such as building slag blocks and metals mixed in domestic garbage are inert materials that do not participate in the pyrolysis reaction, and their density is usually higher than that of organic domestic garbage that can react. In this embodiment, by setting a suitable gas flow rate for the high-temperature gas in the material lifting pipe 5, for example, setting the gas flow rate to 3-5m / s, the gas flow rate can carry organic domestic garbage into the rotary kiln reactor, and the heavy inert materials fall under the action of gravity, thereby achieving the preliminary sorting of garbage, improving the quality of the materials entering the furnace, and improving the efficiency of the system. If the gas flow rate is set too small, it cannot achieve the purpose of fluidized entrainment and screening. If the gas flow rate is set too large, it is easy to cause excessive wear of the material on the pipe wall, affecting the life of the system. In actual use, the gas flow rate can be adjusted according to the moisture and composition of the garbage to achieve the effect of preliminary sorting of the garbage.

[0043] In other embodiments, at least one partition 13 is provided in the material lifting pipe 5 and is arranged along the axial direction of the material lifting pipe 5. The partition 13 divides the internal space of the material lifting pipe 5 into a plurality of air channels. At least one connection port 16 for feeding is provided on the pipe wall of the material lifting pipe 5 corresponding to each air channel.

[0044] In this embodiment, the garbage conveying device 1 includes screw feeders, the number of which is the same as the number of the connecting ports 16 , and the screw feeders are connected to the connecting ports 16 correspondingly.

[0045] It can be understood that when the gas flow rate remains unchanged, the larger the pipe diameter, the slower the gas flow rate; the smaller the pipe diameter, the faster the gas flow rate. In this embodiment, the internal space of the material lifting pipe 5 is divided to reduce the cross-section of the internal airway of the material lifting pipe 5. At the same time, each airway is designed with a screw feeder for separate feeding. This setting is conducive to ensuring the flow rate of high-temperature gas in each airway under a limited gas flow rate, thereby ensuring that organic waste is effectively entrained and quickly mixed with the high-temperature gas. Block materials with higher density, such as metals, slag blocks, and glass blocks, will be initially separated by gas separation.

[0046] See also Figure 2 In this embodiment, two mutually perpendicular partitions 13 are used to divide the internal space of the material lifting pipe 5 into four air channels, and a connecting port 16 is provided on the pipe wall of the material lifting pipe 5 corresponding to each air channel. The garbage conveying device 1 includes four screw feeders, and the four screw feeders are connected to the four connecting ports 16 one by one.

[0047] In other embodiments, the number of screw feeders can be designed according to the amount of garbage processed, thereby dividing the internal space of the material lifting pipe 5.

[0048] See also Figure 1In this embodiment, the rotary kiln waste pyrolysis equipment coupled with the rapid dehydration device further includes a high-temperature gas buffer 3, and the high-temperature gas conveying device is connected to the high-temperature gas buffer 3; a gas outlet is provided at the top of the high-temperature gas buffer 3, and the gas outlet is connected to the inlet of the material lifting pipe 5. The high-temperature gas generated from the rotary kiln reactor is conveyed by the high-temperature gas conveying device to first enter the high-temperature gas buffer 3, and then enter the material lifting pipe 5 upward. The block materials with high density such as metal, slag blocks, and glass blocks separated by the airflow fall into the high-temperature gas buffer 3 by gravity for temporary storage.

[0049] The utility model uses the flow rate of high-temperature gas to sort garbage. To ensure that heavy inert materials and organic garbage are effectively separated, the distance L from the connection port 16 to the inlet of the material lifting pipe 5 is greater than the inner diameter of the material lifting pipe 5. In a preferred embodiment, the distance L from the connection port 16 to the inlet of the material lifting pipe 5 is greater than 3 times the inner diameter of the material lifting pipe 5.

[0050] In this embodiment, the distance L from the connecting port 16 to the inlet of the material lifting pipe 5 is 5 times the inner diameter of the material lifting pipe 5 .

[0051] See also Figure 1 In this embodiment, the rotary kiln garbage pyrolysis equipment coupled with the rapid dehydration device also includes a heavy material slag discharge tank 15, and a slag discharge port 31 is provided at the bottom of the high-temperature gas buffer 3, and the heavy material slag discharge tank 15 is detachably connected to the slag discharge port 31.

[0052] In order to ensure that the high-temperature gas flows upward after entering the high-temperature gas buffer 3, the heavy material discharge tank 15 of this embodiment is operated in an intermittent discharge manner. When it is discharging, it is disconnected from the high-temperature gas buffer 3, and heavy materials such as metals, slag blocks, and glass blocks will be temporarily stored in the high-temperature gas buffer 3. After discharging, the heavy material discharge tank 15 will be reconnected with the high-temperature gas buffer 3, and the temporarily stored materials will fall into the heavy material discharge tank 15 through the discharge port 31 and be discharged from the system in the next discharge process.

[0053] In this embodiment, the outlet 17 of the material lifting pipe faces the inner wall of the rotary kiln reactor.

[0054] Specifically, the rotary kiln reactor includes a reactor inner tube 8 , and the outlet 17 of the material lifting pipe faces the inner wall of the reactor inner tube 8 .

[0055] Specifically, based on the upward movement of the high-temperature gas in the material lifting pipe 5 , the outlet 17 of the material lifting pipe is vertically oriented toward the inner wall of the reactor inner tube 8 .

[0056] It can be understood that the high-temperature gas carries part of the garbage materials upward. In this process, the water in the garbage is quickly evaporated, and the domestic garbage will undergo preliminary pyrolysis. However, due to the short residence time in the material lifting pipe 5, no deep pyrolysis reaction will occur. The dried garbage particles enter the reactor inner tube 8 of the rotary kiln reactor through the outlet 17 of the material lifting pipe. The outlet 17 of the material lifting pipe faces the inner wall of the reactor inner tube 8. This outlet orientation is conducive to the collision between materials and between materials and the high-temperature wall of the reactor inner tube 8, further breaking up the materials. At the same time, the axial movement speed of the garbage materials is minimized, and the effective heating space of the rotary kiln is increased. The inner diameter of the reactor inner tube 8 is much larger than the inner diameter of the material lifting pipe 5, so that after the entrained high-temperature gas enters the reactor inner tube 8, the speed is greatly reduced, preferably below 0.5m / s. At this time, the high-temperature gas loses the ability to entrain solids, and the solid materials gradually settle in the space of the reactor inner tube 8 and slowly move forward with the rotation of the reactor inner tube 8, and a deep pyrolysis reaction occurs. The pyrolysis temperature is 400-500°C and the residence time is 40-60 minutes. The pyrolysis reaction will generate solid pyrolysis carbon, liquid pyrolysis oil and gaseous pyrolysis gas. After the pyrolysis carbon is cooled, it is discharged as a product. After the liquid pyrolysis oil and gaseous pyrolysis gas products are cooled and purified, combustible gas and pyrolysis oil products are obtained. The smoke exhaust gas generated by the combustion is directly discharged after the flue gas is purified.

[0057] See also Figure 1 In this embodiment, the rotary kiln garbage pyrolysis equipment coupled with the rapid dehydration device also includes a pressurized fan 9, which includes an air inlet 93, a first air outlet 91 and a second air outlet 92; the rotary kiln reactor is provided with a combustible gas outlet, and the air inlet 93 of the pressurized fan is connected to the combustible gas outlet; the rotary kiln reactor is provided with a heating chamber 11, and the heating chamber 11 is connected to the first air outlet 91; the second air outlet 92 is connected to the high-temperature gas conveying device.

[0058] Specifically, a burner 10 is provided at the bottom of the heating chamber 11 , and the first air outlet 91 is connected to the burner 10 .

[0059] In this embodiment, part of the combustible gas generated by the rotary kiln reactor is sold as an additional product; the other part enters the pressurized fan 9 for pressurization and reuse. After entering the pressurized fan 9, the combustible gas is divided into two parts. One part is used as energy, and the combustible gas entering the burner 10 of the heating chamber 11 is mixed with air and burned to provide heat for heating the combustible gas and the rotary kiln reactor, ensuring that the temperature in the heating chamber 11 is 400-500°C; the other part enters the high-temperature gas conveying device for heat exchange and is used to dry the garbage raw materials.

[0060] See also Figure 3In this embodiment, the high-temperature gas delivery device includes a high-temperature gas distribution pipe 7, a high-temperature gas collecting pipe 6 and a heating pipe 12; the reactor inner tube 8 passes through the heating chamber 11; the reactor inner tube 8 includes a feed end and a discharge end, the high-temperature gas collecting pipe 6 is arranged around the outer periphery of the feed end, the high-temperature gas distribution pipe 7 is arranged around the outer periphery of the discharge end, and the two ends of the heating pipe 12 are respectively connected to the high-temperature gas distribution pipe 7 and the high-temperature gas collecting pipe 6; the high-temperature gas distribution pipe 7 is connected to the second gas outlet 92.

[0061] In this embodiment, the number of the heating tubes 12 is multiple, and one end of the multiple heating tubes 12 is evenly distributed along the circumference of the high-temperature gas distribution tube 7, and all are connected to the high-temperature gas distribution tube 7; the other end of the multiple heating tubes 12 is evenly distributed along the circumference of the high-temperature gas collecting pipe 6, and all are connected to the high-temperature gas collecting pipe 6.

[0062] Depend on Figure 3 It can be seen that the reactor inner tube 8 is sleeved in the heating chamber 11, and a plurality of heating tubes 12 are evenly arranged in the circumferential direction in the space between the outer wall 14 of the heating chamber and the outer wall of the reactor inner tube 8 to fully utilize the heat of the space for heat exchange.

[0063] Another part of the combustible gas coming out of the pressure blower 9 is used as entrained gas, and first enters the high-temperature gas distribution pipe 7, which is arranged around the outer periphery of the discharge end, and is connected to a plurality of heating pipes 12 and evenly distributed along the circumference, so as to make full use of the heating chamber 11 for heat exchange. The heating pipe 12 passes through the heating chamber 11, and the high-temperature gas inside reaches 400-500°C after heat exchange, and then enters the high-temperature gas collecting pipe 6. The structure of the high-temperature gas collecting pipe 6 is the same as that of the entrained gas distribution pipe 7, and is arranged around the outer periphery of the feed end, and is used to collect the gas in each heating pipe 12.

[0064] In this embodiment, the high temperature gas buffer 3 is provided with a high temperature gas inlet 4 ; the high temperature gas collecting pipe 6 is connected to the high temperature gas inlet 4 of the high temperature gas buffer 3 .

[0065] The high-temperature gas collected by the high-temperature gas collecting pipe 6 enters the high-temperature gas buffer 3 through the high-temperature gas inlet 4 of the high-temperature gas buffer 3, and then enters the material lifting pipe 5 from the gas outlet at the top of the high-temperature gas buffer 3 for drying the domestic waste material.
