Description

Technical Field

[0001] This invention relates to the field of pyrolysis solid waste treatment technology, and in particular to a sludge pyrolysis treatment device based on an energy ball circulation pipe structure. Background Technology

[0002] Currently, there are many technologies and equipment available for the pyrolysis of raw materials such as waste tires and waste plastics, such as rotary kilns. However, a drawback is that many raw materials tend to clump together after heating, making heat absorption difficult. In particular, the internal temperature of the clumps of material cannot reach the pyrolysis temperature for a long time, which seriously affects production efficiency.

[0003] The sludge pyrolysis process, which involves mixing solid waste into sludge, is suitable for municipal solid waste, sludge, and industrial waste such as waste tires and waste plastics. The advantages of pyrolysis include generating less waste gas, being able to treat difficult-to-treat materials unsuitable for incineration or landfill, converting waste into valuable energy, and reducing secondary pollution from incineration and the amount of waste requiring landfill disposal.

[0004] The invention patent with publication number "CN114917843A" discloses a continuous pyrolysis device with multiple energy ball circulation pipes installed on the inner wall of a reactor. The feeding device is sealed to the pyrolysis device. The pyrolysis device includes a heating furnace, a reactor, circulation pipes, ball guide pipes, a separating screen, and a material collection trough. The reactor is rotatably sleeved inside the heating furnace. Multiple circulation pipes are uniformly fixedly installed on the inner wall of the reactor. A ball guide pipe is fixedly installed at one end of the circulation pipe and is connected to one end of the separating screen. The other end of the separating screen is connected to the material collection trough. One end of the reactor is adapted to be connected to the discharge device.

[0005] The patent describes a structure with a circulating energy ball set in the center of the reactor. However, the circulation pipe, the energy ball, and the separation screen for the reaction residue are all located in the same center, resulting in a crowded setup. The energy ball circulation pipe runs through most of the reactor's length, making operation and maintenance difficult. Moreover, the energy ball circulation pipe only serves to guide the energy ball, and the heat of the energy ball continuously decreases during circulation, failing to meet the temperature requirements of different stages of the pyrolysis process. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a sludge pyrolysis treatment device based on an energy ball circulation pipe structure. The technical solution adopted is as follows:

[0007] A sludge pyrolysis treatment device based on an energy ball circulation pipe structure is used to treat solid waste sludge by pyrolysis. The device includes an anaerobic pulverization unit, a pyrolysis reaction unit, and an energy ball circulation unit. The anaerobic pulverization unit includes an isolated feeding device, a closed pulverizing unit, and a sealed discharge auger. The isolated feeding device is located at the top of the closed pulverizing unit to remove air from the incoming solid waste. The closed pulverizing unit pulverizes the solid waste and further removes any remaining air after pulverization. The sealed discharge auger... The discharge auger is located at the discharge port at the bottom of the enclosed crushing device, used to guide the crushed solid waste to be pyrolyzed into the inlet at the top of the pyrolysis reactor. The pyrolysis reactor is equipped with a drying zone, a dry distillation zone, a carbonization zone, and a gasification zone from top to bottom. The energy ball circulation device includes at least two energy ball pipe groups and multiple energy balls. The energy ball pipe groups are spirally arranged inside the pyrolysis reactor, forming an energy ball running channel inside. The multiple energy balls are located in the energy ball running channel and move from top to bottom with the solid waste. The energy ball circulation device is used to provide heating for the solid waste.

[0008] By adopting the above technical solution, solid waste pyrolysis refers to the chemical decomposition process in which combustible solid waste is decomposed at high temperature under anaerobic or oxygen-deficient conditions, and finally becomes combustible gas, oil, and solid carbon. It is a process in which solid waste containing organic combustibles is placed in a completely oxygen-free environment and heated, so that the chemical bonds of organic matter in the solid waste are broken, producing small molecule substances (gas and liquid) and solid residues.

[0009] Conventional pyrolysis processes generally do not take special measures to deal with the air carried by the solid waste entering the pyrolysis reactor, which will affect the pyrolysis reaction efficiency. The oxygen in the air carried by the solid waste will interfere with the pyrolysis process, thus affecting the pyrolysis quality and yield. At the same time, the safety risks will increase: oxygen is flammable and explosive. If there is an excess of oxygen in the anaerobic pyrolysis furnace, it will increase the safety risks of fire and explosion.

[0010] By installing an oxygen-free pulverizing treatment device, the combination of an isolated feeding device, a closed pulverizing device, and a sealed discharge auger can greatly reduce the air carried by the solid waste entering the pyrolysis reactor, thereby improving pyrolysis quality and yield, and reducing safety risks.

[0011] The energy ball pipeline assembly is spirally arranged inside the pyrolysis reaction device, forming an energy ball running channel inside. In addition, multiple heated energy balls are located in the energy ball running channel and move from top to bottom with the solid waste. This can provide a more stable temperature inside the solid waste, making the quality of each area of ​​the pyrolysis reaction more stable and meeting the temperature requirements of different stages of the pyrolysis process.

[0012] Optionally, the isolated feeding device includes a feeding hopper, a hopper gate, a buffer bin, a feeding door, and a vacuum pump. The feeding hopper is installed at the top of the buffer bin, the hopper gate is installed at the junction, and the feeding door is installed at the bottom of the buffer bin. Both the hopper gate and the feeding door are electric doors. The air extraction port of the vacuum pump is connected to the air extraction port on the side wall of the buffer bin through a pipe to remove the air from the solid waste inside the buffer bin.

[0013] By adopting the above technical solution, first open the funnel door and close the feed door. After the crushed solid waste falls from the feed funnel into the buffer chamber, close the funnel door, turn on the vacuum pump to remove more than 90% of the air in the buffer chamber, maintain negative pressure, open the feed door, and the crushed solid waste will fall into the closed crushing device.

[0014] Optionally, the enclosed pulverizing device includes a solid waste pulverizer, a vacuum detection module, and a microcontroller-based air extraction controller. The feed inlet at the top of the solid waste pulverizer is connected to the bottom of the buffer bin above the feed door. When the feed door is open, the solid waste to be pulverized falls into the pulverizing chamber of the solid waste pulverizer. The discharge outlet at the bottom of the solid waste pulverizer is connected to the feed inlet of the sealed discharge auger. The air extraction port of the vacuum pump is connected to the air extraction port set on the side wall of the pulverizing chamber of the solid waste pulverizer through a pipe. The vacuum detection module detects the vacuum degree in the pulverizing chamber of the solid waste pulverizer and transmits it to the air extraction controller. When the air extraction controller determines that the measured vacuum degree value is greater than a set threshold, it controls the vacuum pump to start air extraction. The solid waste pulverizer pulverizes the solid waste to be pyrolyzed into particles with a particle size of less than one centimeter, which can ensure a more stable quality and yield of the subsequent pyrolysis reaction.

[0015] By adopting the above technical solution, the closed crushing device is mainly based on a solid waste crusher. The upstream and isolated feeding device form a sealed feeding system. During the crushing operation, air is also extracted at the same time. Some solid waste will release the internal air during the crushing process to avoid this part of the air affecting the pyrolysis reaction. When the vacuum controller determines that the measured vacuum value is greater than the set threshold, it controls the vacuum pump to start the extraction. The set threshold here is a vacuum degree of 90%. While ensuring the stability of the subsequent pyrolysis reaction, it avoids the risks caused by vacuuming.

[0016] Optionally, the pyrolysis reaction device is a pyrolysis reactor with an energy ball inlet at the top and an energy ball outlet at the bottom. An energy ball inlet gate and an energy ball outlet gate are respectively provided at the energy ball inlet and outlet.

[0017] Optionally, the energy ball pipeline assembly includes at least three spiral tubes. The three spiral tubes are installed inside the pyrolysis reaction device and pass through the drying zone, the dry distillation zone, the carbonization zone and the gasification zone. Their two ends are connected to the energy ball inlet and the energy ball outlet, respectively. The interior of the three spiral tubes forms an energy ball running channel.

[0018] By adopting the above technical solution, the design concept of the energy ball pipeline group is to arrange at least three spiral tubes in parallel spirals, preferably four spiral tubes in parallel spirals. The internal area is the energy ball running channel. In actual use, the heated energy ball and the granular solid waste are put in together. Under the entanglement of the granular solid waste, it falls slowly. During the fall, it passes through the drying zone, the dry distillation zone, the carbonization zone and the gasification zone respectively. The energy ball provides heat inside the granular solid waste, which improves the problem of incomplete pyrolysis reaction caused by uneven heating inside and outside the granular solid waste.

[0019] Optionally, the spiral tube includes a first heating section, a second heating section, and a third heating section, which are located at the intersection of the drying zone and the dry distillation zone, the intersection of the dry distillation zone and the carbonization zone, and the intersection of the carbonization zone and the gasification zone, respectively.

[0020] Optionally, the first heating section, the second heating section, and the third heating section are all electric heating tubes, with the temperature of the first heating section being 300℃-350℃, the temperature of the second heating section being 600℃-650℃, and the temperature of the third heating section being 1000℃-1100℃.

[0021] By adopting the above technical solution, the spiral tube is additionally designed with three heating sections: the first heating section, the second heating section, and the third heating section. These sections are located at the intersection of the drying zone and the dry distillation zone, the intersection of the dry distillation zone and the carbonization zone, and the intersection of the carbonization zone and the gasification zone, respectively. This changes the traditional design concept of high-temperature entry of the energy ball, making the energy ball more compatible with the temperature of each pyrolysis zone, and making the solid waste pyrolysis effect more stable and complete.

[0022] Optionally, it also includes a microcontroller-based electric heating controller, which is electrically connected to the first heating section, the second heating section and the third heating section respectively, and controls the power of the first heating section, the second heating section and the third heating section.

[0023] By adopting the above technical solution, the first heating section, the second heating section and the third heating section are all electric heaters, and the heating temperature can be adjusted under the control of the electric heating controller to match the pyrolysis process.

[0024] Optionally, the energy sphere includes a heat-conducting outer shell and a heat storage body, wherein the heat storage body is disposed inside the heat-conducting outer shell, and the heat-conducting outer shell is a sphere.

[0025] By adopting the above technical solution, the heat-conducting outer shell is generally a metal sphere shell, which can quickly conduct heat to the heat storage body during heating and release the heat stored in the heat storage body when moving inside the solid waste.

[0026] Optionally, a stop bar is provided at the end of the first heating section, the second heating section, and the third heating section. The stop bar is set on the side wall of the pyrolysis reaction device through a telescopic device. The telescopic part of the telescopic device drives the stop bar to be located at the end of the first heating section, the second heating section, or the third heating section to block the energy ball from falling.

[0027] By adopting the above technical solution, baffles can be set at the ends of the first heating section, the second heating section and the third heating section to control the falling of the energy ball, so that the energy ball is heated more fully in the first heating section, the second heating section and the third heating section to match the pyrolysis temperature requirements of each region.

[0028] In summary, the present invention has at least one of the following beneficial technical effects:

[0029] This invention provides a sludge pyrolysis treatment device based on an energy ball circulation pipe structure. It incorporates an anaerobic pulverizing device, and through the combined use of an isolated feeding device, a closed pulverizing device, and a sealed discharge auger, it significantly reduces the amount of air carried by the solid waste entering the pyrolysis reactor, improving pyrolysis quality and yield while reducing safety risks. The energy ball pipe assembly is spirally arranged within the pyrolysis reactor, forming an internal energy ball running channel. Multiple heated energy balls, located within this channel, move downwards with the solid waste, providing a more stable temperature within the solid waste. This ensures more stable quality across different areas of the pyrolysis reaction, meeting the temperature requirements of different stages of the pyrolysis process. Attached Figure Description

[0036] This invention discloses a sludge pyrolysis treatment device based on an energy ball circulation pipe structure.

[0037] Reference Figure 1 - Figure 4 Example 1: A sludge pyrolysis treatment device based on an energy ball circulation pipe structure. This device is used to treat solid waste sludge using pyrolysis. The sludge pyrolysis treatment device includes an anaerobic pulverization treatment device, a pyrolysis reaction device 2, and an energy ball circulation device. The anaerobic pulverization treatment device includes an isolated feeding device 11, a closed pulverizing device, and a sealed discharge auger 13. The isolated feeding device 11 is located at the top of the closed pulverizing device to remove air from the incoming solid waste. The closed pulverizing device pulverizes the solid waste and further removes any remaining air after pulverization. The sealed discharge auger... 13 is a discharge port located at the bottom of the closed crushing device, used to introduce the crushed solid waste to be pyrolyzed into the inlet at the top of the pyrolysis reaction device 2. The pyrolysis reaction device 2 is provided with a drying zone, a dry distillation zone, a carbonization zone and a gasification zone from top to bottom. The energy ball circulation device includes at least two energy ball pipe groups 33 and multiple energy balls 34. The energy ball pipe groups 33 are spirally arranged inside the pyrolysis reaction device 2, forming an energy ball running channel 3311 inside. Multiple energy balls 34 are located in the energy ball running channel 3311 and move from top to bottom with the solid waste. The energy ball circulation device is used to provide heating for the solid waste.

[0038] Solid waste pyrolysis refers to the chemical decomposition process in which combustible solid waste is decomposed at high temperatures under anaerobic or oxygen-deficient conditions, ultimately becoming combustible gases, oils, and solid carbon. It involves heating solid waste containing organic combustibles in a completely oxygen-free environment, causing the chemical bonds of the organic matter in the solid waste to break, producing small molecule substances (gas and liquid) and solid residues.

[0039] Conventional pyrolysis processes generally do not take special measures to treat the air carried by the solid waste entering the pyrolysis reactor 2, which will affect the pyrolysis reaction effect. The oxygen in the air carried by the solid waste will interfere with the pyrolysis process, thus affecting the pyrolysis quality and yield. At the same time, the safety risks will increase: oxygen is flammable and explosive. If there is an excess of oxygen in the anaerobic pyrolysis furnace, it will increase the safety risks of fire and explosion.

[0040] An oxygen-free pulverizing treatment device is set up. The combination of an isolated feeding device 11, a closed pulverizing device, and a sealed discharge auger 13 can greatly reduce the air carried in the solid waste entering the pyrolysis reaction device 2, improve the pyrolysis quality and output, and reduce safety risks.

[0041] The energy ball pipeline group 33 is spirally arranged inside the pyrolysis reaction device 2, forming an energy ball running channel 3311 inside. In addition, multiple heated energy balls 34 are located in the energy ball running channel 3311 and move from top to bottom with the solid waste. This can provide a more stable temperature inside the solid waste, making the quality of each area of ​​the pyrolysis reaction more stable and meeting the temperature requirements of different stages of the pyrolysis process.

[0042] Example 2: The isolated feeding device 11 includes a feeding funnel 111, a funnel gate 112, a buffer chamber 113, a feeding gate 114, and a vacuum pump 115. The feeding funnel 111 is provided at the top of the buffer chamber 113, the funnel gate 112 is provided at the junction, and the feeding gate 114 is provided at the bottom of the buffer chamber 113. Both the funnel gate 112 and the feeding gate 114 are electric gates. The air extraction port of the vacuum pump 115 is connected to the air extraction port on the side wall of the buffer chamber 113 through a pipe, and is used to extract the air from the solid waste in the buffer chamber 113.

[0043] First, open the funnel door 112 and close the feed door 114. Wait for the crushed solid waste to fall from the feed funnel 111 into the buffer chamber 113. Then, close the funnel door 112 and turn on the vacuum pump 115 to remove more than 90% of the air in the buffer chamber 113. After maintaining negative pressure, open the feed door 114 and the crushed solid waste will fall into the closed crushing device.

[0044] Example 3: The closed-loop pulverizing device includes a solid waste pulverizer 121, a vacuum detection module 122, and a microcontroller-based air extraction controller 123. The feed inlet at the top of the solid waste pulverizer 121 is connected to the bottom of the buffer chamber 113 above the feed door 114. When the feed door 114 is open, the solid waste to be pulverized falls into the pulverizing chamber of the solid waste pulverizer 121. The discharge outlet at the bottom of the solid waste pulverizer 121 is connected to the feed inlet of the sealed discharge auger 13. The air extraction port of the vacuum pump 115 is connected to the air extraction port set on the side wall of the pulverizing chamber of the solid waste pulverizer 121 through a pipe. The vacuum detection module 122 detects the vacuum degree in the pulverizing chamber of the solid waste pulverizer 121 and transmits it to the air extraction controller 123. When the air extraction controller 123 determines that the measured vacuum degree value is greater than the set threshold, it controls the vacuum pump 115 to start air extraction. The solid waste pulverizer 121 pulverizes the solid waste to be pyrolyzed into particles with a particle size of less than one centimeter, which can ensure a more stable quality and yield of the subsequent pyrolysis reaction.

[0045] The enclosed crushing device is mainly based on the solid waste crusher 121. It forms a sealed feeding system with the isolated feeding device 11 upstream. During the crushing process, air is also extracted at the same time. Some solid waste will release the internal air during the crushing process to avoid this part of the air affecting the pyrolysis reaction. When the vacuum controller 123 determines that the measured vacuum value is greater than the set threshold, it controls the vacuum pump 115 to start the vacuum extraction. The set threshold here is a vacuum degree of 90%. While ensuring the stability of the subsequent pyrolysis reaction, it avoids the risks caused by vacuum extraction.

[0046] Example 4: The pyrolysis reaction device 2 is a pyrolysis reactor with an energy ball inlet at the top and an energy ball outlet at the bottom. An energy ball inlet gate 21 and an energy ball outlet gate 22 are respectively provided at the energy ball inlet and outlet.

[0047] Example 5: The energy ball pipeline group 33 includes at least three spiral tubes 331. The three spiral tubes 331 are arranged in the pyrolysis reaction device 2 and pass through the drying zone, the dry distillation zone, the carbonization zone and the gasification zone. Both ends are connected to the energy ball inlet and the energy ball outlet, respectively. The three spiral tubes 331 form an energy ball running channel 3311 inside.

[0048] The design concept of the energy ball pipeline group 33 is that at least three spiral tubes 331 are arranged in parallel spirals, preferably four spiral tubes 331 are arranged in parallel spirals. The internal area is the energy ball running channel 3311. In actual use, the heated energy ball 34 is put in together with the granular solid waste. Under the entanglement of the granular solid waste, it slowly falls. During the fall, it passes through the drying zone, the dry distillation zone, the carbonization zone and the gasification zone respectively. The energy ball 34 provides heat inside the granular solid waste, which improves the problem of incomplete pyrolysis reaction caused by uneven heating inside and outside the granular solid waste.

[0049] Example 6: The spiral tube 331 includes a first heating section 332, a second heating section 333, and a third heating section 334. The first heating section 332, the second heating section 333, and the third heating section 334 are located at the intersection of the drying zone and the dry distillation zone, the intersection of the dry distillation zone and the carbonization zone, and the intersection of the carbonization zone and the gasification zone, respectively.

[0050] In Example 7, the first heating section 332, the second heating section 333, and the third heating section 334 are all electric heating tubes. The temperature of the first heating section 332 is 300℃-350℃, the temperature of the second heating section 333 is 600℃-650℃, and the temperature of the third heating section 334 is 1000℃-1100℃.

[0051] The spiral tube 331 is additionally designed with three heating sections: the first heating section 332, the second heating section 333, and the third heating section 334. These sections are located at the intersection of the drying zone and the dry distillation zone, the intersection of the dry distillation zone and the carbonization zone, and the intersection of the carbonization zone and the gasification zone, respectively. This design changes the traditional high-temperature entry concept of the energy ball, making the energy ball more compatible with the temperature of each pyrolysis zone, and making the solid waste pyrolysis effect more stable and complete.

[0052] Example 8 also includes a microcontroller-based electric heating controller, which is electrically connected to the first heating section 332, the second heating section 333 and the third heating section 334 respectively, and controls the power of the first heating section 332, the second heating section 333 and the third heating section 334.

[0053] The first heating section 332, the second heating section 333, and the third heating section 334 are all electric heaters. Under the control of the electric heating controller, the heating temperature can be adjusted to match the pyrolysis process.

[0054] Example 9: The energy ball 34 includes a heat-conducting outer shell 341 and a heat storage body 342. The heat storage body 342 is disposed inside the heat-conducting outer shell 341, which is a sphere.

[0055] The heat-conducting outer shell 341 is generally a metal spherical shell, which can quickly conduct heat to the heat storage body 342 during heating and release the heat stored in the heat storage body 342 when moving inside the solid waste.

[0056] In Example 10, a stop bar 335 is provided at the end of the first heating section 332, the second heating section 333, and the third heating section 334. The stop bar 335 is provided on the side wall of the pyrolysis reaction device 2 through a telescopic device 336. The telescopic part of the telescopic device 336 drives the stop bar 335 to be located at the end of the first heating section 332, the second heating section 333, or the third heating section 334 to block the energy ball 34 from falling.

[0057] Stop bars 335 can be installed at the ends of the first heating section 332, the second heating section 333, and the third heating section 334 to control the falling of the energy ball 34, so that the energy ball 34 is heated more fully in the first heating section 332, the second heating section 333, and the third heating section 334 to match the pyrolysis temperature requirements of each region. The telescopic device 336 can be a mechanically controllable, high-temperature resistant electric telescopic rod.

[0058] A closed discharge auger can be installed at the bottom of the pyrolysis reactor to remove the solid waste generated after the pyrolysis reaction.

[0059] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
