Description

Technical Field

[0001] The invention relates to the technical field of industrial and solid waste pyrolysis treatment, and in particular to a pyrolysis combustion chamber structure for solid waste treatment. Background Art

[0002] Pyrolysis is a very environmentally friendly and efficient technology for treating organic solid waste. It can be used to treat various agricultural and forestry wastes, industrial solid wastes, hazardous wastes, domestic garbage and other organic solid wastes. Among the pyrolysis products of organic solid waste, there are three main phases of substances, namely pyrolysis gas, pyrolysis liquid and pyrolysis carbon. Part of the pyrolysis gas produced after the pyrolysis of organic matter provides pyrolysis energy for its own pyrolysis, and the excess combustible gas can be used for energy applications.

[0003] Most of the burners that provide the capability of existing pyrolysis equipment currently use simple Venturi burners to directly heat the pyrolysis carbonization cylinder with flames. Although this structure is simple, there is also the problem that the high-temperature flame directly heats the carbonization cylinder, causing local high-temperature oxidation and corrosion of the carbonization cylinder. In addition, the local high temperature is also likely to cause uneven thermal stress on the carbonization cylinder, causing it to deform and damage the carbonization cylinder. In severe cases, it will also cause the carbonization cylinder to be unusable and scrapped. Traditional pyrolysis combustion chambers usually use fossil fuels such as natural gas as the initial heat source to start the pyrolysis process. After pyrolysis produces combustible gas, it switches to the pyrolysis gas itself as fuel. However, this conversion process often relies on manual judgment of the pyrolysis gas concentration and manual ignition, which is not only inefficient but also poses safety risks. In addition, the flame flow path in the combustion chamber is short and the combustion is incomplete, resulting in unburned gas in the emissions, which not only pollutes the environment but also reduces the energy efficiency of the pyrolysis combustion chamber. For this reason, a pyrolysis combustion chamber structure for solid waste treatment is proposed. Summary of the invention

[0004] The object of the present invention is to provide a pyrolysis combustion chamber structure for solid waste treatment to solve the problems raised in the above background technology.

[0006] Preferably, the air inlet ends of the first air branch pipe and the second air branch pipe are respectively connected to an air collecting pipe, and the air inlet ends of the air collecting pipe are connected to an oxygen air inlet pipe.

[0007] Preferably, the above-mentioned: a burner is connected to one side of the nozzle, the second air inlet pipe is communicated with the first air vent, and the first air inlet pipe is communicated with the second air vent.

[0008] Preferably, the above-mentioned: the inner wall of the fire wall is respectively provided with a first combustion chamber and a second combustion chamber located on both sides of the baffle, the gas supply groove is respectively connected with the first combustion chamber and the second combustion chamber, and the first air hole, the insertion hole and the second air hole are all located on the inner side of the first combustion chamber.

[0009] Preferably, as mentioned above: a valve is installed at one end of the bottom of the third air inlet pipe, scale lines are provided on the surface of the transparent window, and the valve is located on one side of the top of the collection box.

[0010] Preferably, the connection assembly comprises a limit plate and a fixing frame, a limit groove and a slide groove are respectively provided inside the fixing frame, and a locking groove is provided on one side of the limit plate.

[0011] Preferably, as mentioned above: a slide plate is slidably connected to the inner side of the slide groove, and a spring is connected between one side of the slide plate and the inner side of the slide groove.

[0012] Preferably, as mentioned above: a locking rod is fixed to one side of the slide, when the locking rod is inserted into the inner side of the locking slot, the collection box is in an installed state, and when the locking rod leaves the inner side of the locking slot, the collection box is in a disassembled state.

[0013] Preferably, as mentioned above: a handle is fixed to one end of the locking rod, and the outer side of the locking rod is inserted into one side of the fixing frame.

[0014] Preferably, as mentioned above: one side of the limiting plate is fixed to one side of the collecting box, and one side of the fixing frame is fixed to one side of the box body.

[0015] Compared with the prior art, the present invention adopts the above technical solution and has the following technical effects: The flame of the burner is preferentially sprayed toward the firewall through the nozzle. When the pyrolysis combustion chamber enters the normal pyrolysis mode and produces pyrolysis combustible gas, as long as the concentration of the pyrolysis combustible gas reaches a certain proportion, the pyrolysis combustible gas transported by the first air vent and the second air vent will automatically ignite when it touches the high-temperature firewall. At this time, the combustion of the natural gas burner is stopped, so that the pyrolysis combustion chamber enters the stage where the pyrolysis combustible gas provides pyrolysis energy, achieving a smooth transition from natural gas combustion to pyrolysis gas combustion. There is no need to manually judge whether the concentration of the pyrolysis combustible gas has reached the ignition point, and the safety risks that may be caused by frequent manual attempts to ignite are avoided, reducing errors and potential dangers in human operation, and improving the safety and reliability of the system.

[0016] By providing a baffle in the middle of the inner wall of the firewall, the flame needs to complete two degrees of flow turning in the first combustion chamber, the second combustion chamber and the gas trough, which greatly increases the residence time and combustion path of the flame in the combustion chamber. A longer combustion path means that the fuel has more time to mix with oxygen and burn, thereby improving the combustion efficiency. The flame is fully burned in the combustion chamber, thereby avoiding the discharge of unburned gas into the external environment, which not only reduces environmental pollution, but also improves the overall energy efficiency of the pyrolysis combustion chamber.

[0017] During the pyrolysis gas transportation process, tar is easily adsorbed on the side wall of the third intake pipe and gathers at the bottom of the pipe under the action of gravity. Through the transparent window and scale lines, workers can visually observe the amount of tar collected and promptly discharge the tar into the collection box by opening the valve, effectively preventing the risk of tar clogging the first and second intake pipes and ensuring the continued normal operation of the combustion system. Regular tar cleaning can reduce carbon deposits in the pipeline and combustion chamber, thereby extending the life of system components, simplifying the tar cleaning process, reducing the frequency of system maintenance due to tar accumulation, and extending the overall service life of the pyrolysis combustion chamber.

[0018] By pulling the handle, the locking rod and the slide plate are driven to move, and the slide plate compresses the spring, so that the locking rod leaves the inner side of the lock slot and the collection box is pulled to one side. The collection box drives the limit plate to leave the inner side of the limit slot. At this time, the tar collected inside the collection box can be cleaned, and the handle is pulled again to insert the limit plate into the inner side of the limit slot. The pulling force of the handle is released to complete the installation of the collection box. The worker only needs to pull the handle to easily unlock and take out the collection box to clean the tar. After cleaning, the collection box can be reinstalled through simple operations, which greatly simplifies the maintenance process. BRIEF DESCRIPTION OF THE DRAWINGS

When the vertically arranged third air inlet pipe 10 transports pyrolysis gas, the tar inside the pyrolysis gas will be adsorbed on the side wall of the third air inlet pipe 10. Under the action of gravity, the tar gathers at the bottom of the third air inlet pipe 10. A scale line 6 is provided on the surface of the transparent window 7. The valve 4 is located on the top side of the collecting box 5. The worker can visually observe the tar collection amount by observing the scale line 6 on the upper side of the transparent window 7. When the valve 4 is opened, the tar enters the inner side of the collecting box 5, thereby preventing the tar from clogging the first air inlet pipe 8 and the second air inlet pipe 9.

[0026] A collecting box 5 is provided at the bottom of the third air inlet pipe 10, and a connecting assembly 2 for disassembling and assembling the collecting box 5 is provided on one side of the box body 1.

[0027] When the handle 29 is pulled to one side, the handle 29 drives the locking rod 25 and the sliding plate 26 to move with it, and the sliding plate 26 compresses the spring 27. When the locking rod 25 is inserted into the inner side of the locking groove 24, the collecting box 5 is in the installed state. When the locking rod 25 leaves the inner side of the locking groove 24, the collecting box 5 is in the disassembled state. A handle 29 is fixed to one end of the locking rod 25, and the outer side of the locking rod 25 is inserted into one side of the fixing frame 22, so that the locking rod 25 leaves the inner side of the locking groove 24 and the collecting box 5 is pulled to one side, the collecting box 5 drives the limiting plate 21 to leave the inner side of the limiting groove 23. At this time, the tar collected in the collecting box 5 can be cleaned, and one side of the limiting plate 21 is fixed to one side of the collecting box 5, and one side of the fixing frame 22 is fixed to one side of the box body 1. The collecting box 5 can be reinstalled by simple operation, which greatly simplifies the maintenance process.

[0028] Working principle: When the pyrolysis combustion chamber needs to be started, the burner is first used to spray natural gas flames into the first combustion chamber 181 through the nozzle 3 inside the insertion hole 20. The natural gas flames are directly shot toward the firewall 16 inside the box body 1 to heat it to a high temperature state; Then, the pyrolysis gas enters the inner side of the first intake pipe 8 and the second intake pipe 9 through the third intake pipe 10, and the pyrolysis gas is sprayed toward the inner wall of the firewall 16 inside the first combustion chamber 181 through the first vent hole 191 and the second vent hole 192. As the pyrolysis combustion chamber gradually heats up and enters the normal pyrolysis mode, when the concentration of the pyrolysis gas delivered by the third intake pipe 10 reaches the ignition point and contacts the high-temperature firewall 16, the pyrolysis gas will be automatically ignited, thereby achieving a smooth transition of the pyrolysis combustion chamber, from natural gas combustion to pyrolysis gas combustion, without having to manually judge whether the concentration of the pyrolysis combustible gas has reached the ignition point, and avoiding the insecurity caused by manual attempts to ignite. When the third air intake pipe 10 transports pyrolysis gas, the oxygen air intake pipe 12 transports oxygen inwardly, and the oxygen passes through the inner side of the air collecting pipe 13, and is transported to the inner sides of the first air distribution pipe 14 and the second air distribution pipe 15 through the air collecting pipe 13, and is transported to the box body 1 through the first air intake pipe 8 and the second air intake pipe 9 to participate in pyrolysis combustion. At this time, the first air vent 191 and the second air vent 192 simultaneously spray flames toward one side of the firewall 16, and the ratio of pyrolysis gas to oxygen can be adjusted according to the amount of pyrolysis gas generated and the combustion demand; At this time, the baffle 17 plays a key role. It is located on the side of the firewall 16 away from the first air vent 191 and the second air vent 192, and its height is higher than the top of the first air vent 191 and the second air vent 192. The flame first flows to the firewall 16 close to the first air vent 191 and the second air vent 192 in the first combustion chamber 181, and then flows to the upper part of the baffle 17 through the gas conveying groove 30 between the firewall 16 and the baffle 17 to enter the inner side of the first combustion chamber 181, and is discharged through the outlet pipe 11. In this process, the flame needs to complete two 180-degree flow turns, thereby increasing the residence time and combustion path of the flame in the first combustion chamber 181 and the second combustion chamber 182, ensuring that the flame is fully burned before reaching the outlet pipe 11, thereby avoiding the discharge of unburned gas into the external environment.

[0029] At this time, when the third vertically arranged air inlet pipe 10 is conveying pyrolysis gas, the tar inside the pyrolysis gas will be adsorbed on the side wall of the third air inlet pipe 10. Under the action of gravity, the tar will gather at the bottom of the third air inlet pipe 10. The worker can visually observe the amount of tar collected by observing the scale line 6 on the upper side of the transparent window 7, and open the valve 4. At this time, the tar enters the inner side of the collection box 5, and the tar is prevented from clogging the first air inlet pipe 8 and the second air inlet pipe 9. The amount of tar flowing to the first air inlet pipe 8 and the second air inlet pipe 9 by pyrolysis is greatly reduced, so that the combustion system can maintain normal operation for a longer period of time and will not be blocked by tar before the maintenance period arrives. When the collecting box 5 has collected a certain amount of tar and needs to be disassembled for cleaning, it is only necessary to pull the handle 29 to one side, at which time the handle 29 drives the locking rod 25 and the slide plate 26 to move accordingly, and at the same time the slide plate 26 compresses the spring 27, at which time the locking rod 25 leaves the inner side of the locking groove 24, and the collecting box 5 is pulled to one side, and the collecting box 5 drives the limiting plate 21 to leave the inner side of the limiting groove 23, and at this time the tar collected in the collecting box 5 can be cleaned; After cleaning, the limit plate 21 on one side of the collection box 5 is aligned with the limit groove 23, and then the handle 29 is pulled again, and then the limit plate 21 is inserted into the inner side of the limit groove 23, and the pulling force of pulling the handle 29 is released. At this time, under the elastic force of the spring 27, the slide plate 26 is pushed to slide on the inner side of the slide groove 28, so that the slide plate 26 drives the locking rod 25 to move toward the inner side of the locking groove 24. When the locking rod 25 is inserted into the inner side of the locking groove 24, the installation of the collection box 5 is completed.

[0030] In summary, the flame of the burner is preferentially sprayed toward the firewall 16 through the nozzle 3. When the pyrolysis combustion chamber enters the normal pyrolysis mode and produces pyrolysis combustible gas, as long as the concentration of the pyrolysis combustible gas reaches a certain proportion, the pyrolysis combustible gas delivered by the first vent 191 and the second vent 192 will automatically ignite when it hits the high-temperature firewall 16. At this time, the combustion of the natural gas burner is stopped, so that the pyrolysis combustion chamber enters the stage where the pyrolysis combustible gas provides pyrolysis energy, achieving a smooth transition from natural gas combustion to pyrolysis gas combustion. There is no need to manually judge whether the concentration of the pyrolysis combustible gas has reached the ignition point, and the safety risks that may be caused by frequent manual attempts to ignite are avoided, reducing errors and potential dangers in human operations, and improving the safety and reliability of the system. By providing a baffle 17 in the middle of the inner wall of the firewall 16, the flame needs to complete two 180-degree flow turns in the first combustion chamber 181, the second combustion chamber 182 and the gas delivery groove 30, which greatly increases the residence time and combustion path of the flame in the combustion chamber. The longer combustion path means that the fuel has more time to mix with oxygen and burn, thereby improving the combustion efficiency. The flame is fully burned in the combustion chamber, thereby avoiding the discharge of unburned gas into the external environment, which not only reduces environmental pollution, but also improves the overall energy efficiency of the pyrolysis combustion chamber. During the pyrolysis gas transportation process, tar is easily adsorbed on the side wall of the third air inlet pipe 10 and gathers at the bottom of the pipe under the action of gravity. Through the transparent window 7 and the scale line 6, workers can visually observe the amount of tar collected and timely discharge the tar into the collection box 5 by opening the valve 4, which effectively prevents the risk of tar blocking the first air inlet pipe 8 and the second air inlet pipe 9, ensuring the continuous normal operation of the combustion system. Regular cleaning of tar can reduce carbon deposits in the pipeline and the combustion chamber, thereby extending the life of system components, simplifying the tar cleaning process, reducing the system maintenance frequency caused by tar accumulation, and extending the overall service life of the pyrolysis combustion chamber; By pulling the handle 29, the locking rod 25 and the slide plate 26 are driven to move accordingly. The slide plate 26 compresses the spring 27, and the locking rod 25 leaves the inner side of the locking groove 24. The collecting box 5 is pulled to one side, and the collecting box 5 drives the limiting plate 21 to leave the inner side of the limiting groove 23. At this time, the tar collected inside the collecting box 5 can be cleaned. The handle 29 is pulled again to insert the limiting plate 21 into the inner side of the limiting groove 23. The pulling force of the pulling handle 29 is released to complete the installation of the collecting box 5. The worker only needs to pull the handle 29 to easily unlock and take out the collecting box 5 to clean the tar. After cleaning, the collecting box 5 can be reinstalled through simple operations, which greatly simplifies the maintenance process.
