Description

Technical Field

[0001] The invention relates to the technical field of kilns, and in particular to a high-efficiency solid waste incinerator. Background Art

[0002] Kilns are commonly used equipment in industrial production. Their main purpose is heat treatment. According to different heating methods, they are mainly divided into two types. One is direct heating, which is to place fuel or gas directly in or outside the kiln. During the combustion process, high-temperature heat is generated that directly acts on the materials in the kiln to achieve heating. Common direct heating methods include fuel combustion (such as coal, wood, etc.), gas combustion (such as natural gas, liquefied gas, etc.); the other is indirect heating, which is to transfer the heat generated by the combustion of fuel or gas to the medium (such as air, liquid) and then act on the materials in the kiln to achieve heating. Common indirect heating methods include thermal oil heating, steam heating, electric heating, etc., and those used for solid waste treatment are usually directly heated kilns.

[0003] Solid waste incinerators are mainly divided into iron mesh incinerators, grate incinerators, fluidized bed incinerators, rotary incinerators, and dumping furnaces. In the rotary incinerator, the garbage passes through the rotating combustion chamber and is surrounded by high-temperature heat energy in all directions, which accelerates the combustion process and reduces the content of emissions. It is not only used for the treatment of solid waste, but also widely used for the heat treatment of solid materials such as refractory materials. In order to improve the combustion effect, the technicians in this field mainly achieve it through the following methods: controlling the combustion effect of the burner, changing the movement state of the material in the rotary furnace, and pre-treating the material.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0016] Example 1 like Figure 1-7As shown, a high-efficiency solid waste incinerator is used for processing pre-dried and crushed solid waste, including a frame 1, the frame 1 is a steel structure frame, a combustion kiln 2 is fixed on the frame 1, the combustion kiln 2 is connected to a burner 3, the burner 3 is a natural gas burner 3, the natural gas burner 3 is connected to a fuel pipe 7 and a combustion-supporting gas pipe 19, the combustion kiln 2 is connected to a feeding device, the feeding device includes a feeding auger 4 installed at the upper end of the combustion kiln 2, the discharge end of the feeding auger 4 has a compression isolation structure, the feeding end of the feeding auger 4 has a feeding hopper 5, specifically, the outlet of the feeding hopper 5 is long, so that the solid waste can be separated from the feeding auger 4 more fully contact, so that the feeding auger 4 on the discharge side of the feeding hopper 5 is filled with solid garbage, so that the compression isolation structure is fully fed. The compression isolation structure includes a small pitch auger 24 arranged at the end of the feeding auger 4. The pitch of the small pitch auger 24 gradually decreases from the feeding end to the discharging end. The main components of solid garbage are paper, plastic products, wood, cloth, etc. When conveyed through the feeding auger 4, more gaps will be generated, thereby causing smoke leakage and other phenomena, polluting the surrounding air environment. Through the compression isolation structure, the solid garbage at the discharge end of the feeding device can be made dense, reducing smoke overflow, and the compression isolation structure and the combustion kiln 2 are connected. A dispersion structure is also installed, which includes a blanking barrel 6 sealed and connected between the feed auger 4 and the combustion kiln 2. The blanking barrel 6 is installed vertically, and the cross-section of the blanking barrel 6 is rectangular. A stirring shaft 22 is installed in the blanking barrel 6, and stirring teeth 23 are installed on the stirring shaft 22. The stirring teeth 23 are blades, thereby dispersing the solid waste, so that the solid waste is fully contacted with the flame of the burner 3, and then fully burned, reducing the combustion residue. In this embodiment, the small-pitch auger 24 is connected to a pulley 17, and the stirring shaft 22 is connected to a pulley 2 18. The diameter of the pulley 17 is 6-8 times the diameter of the pulley 2 18. The stirring shaft 22 is rotated at high speed to ensure the dispersion effect of solid waste. The minimum blade spacing value of the small-pitch auger 24 is 1 / 2 of the blade spacing value of the feed auger 4. In order to improve the compression effect, the small-pitch auger 24 is a variable diameter auger, and the outer diameter gradually decreases from the feed end to the discharge end, thereby improving the compression effect and the sealing effect. During the test, an attempt was made to install a refractory grid at the lower end of the blanking barrel 6 in the combustion kiln 2 to allow the solid waste to fall onto the grid and then burn on the grid. The test found that since the grid is close to the outlet of the blanking barrel 6, accumulation will occur on the grid, and the grid is in a high temperature environment for a long time and is easily damaged.

[0017] The combustion kiln 2 is connected to the rotary kiln 8. The combustion kiln 2 has a first-level pushing structure for pushing materials toward the rotary kiln 8. Specifically, the combustion kiln 2 includes a steel shell 201, which is connected to the frame 1. The first-level pushing structure includes an inner lining layer 202 fixed in the steel shell 201. The inner lining layer 202 is a prefabricated refractory material layer. The lower end of the inner lining layer 202 is prefabricated with a pushing slope. In the combustion kiln 2, due to the effect of the dispersion structure, the solid waste does not gather and fall, and through the disturbance of the combustion airflow, the solid waste can move toward the rotary kiln 8 in the combustion kiln 2. Part of the solid waste falls on the inner lining layer 202, and slides toward the rotary kiln 8 under the disturbance of gravity and the combustion airflow, thereby avoiding accumulation in the combustion kiln 2. During the test, it was found that without using the dispersion structure , more solid waste falls to the bottom of the combustion kiln 2, and the combustion is not complete, resulting in material accumulation at the lower end of the combustion kiln 2, which needs to be cleaned regularly. If the combustion kiln 2 is rotated, the accumulation of materials at the lower end of the combustion kiln 2 can be effectively avoided. At present, most rotary combustion kilns 2 install the burner 3 at the kiln head, which can ensure sufficient combustion. The disadvantage is that the kiln needs to be stopped regularly for feeding and discharging. During the test process, it was found that in this embodiment, due to the small amount of solid waste falling into the bottom of the inner lining layer 202, the solid waste is still burning at the bottom of the inner lining layer 202, and the heat is transferred to the bottom of the inner lining layer 202, thereby making the bottom of the inner lining layer 202 high-temperature, so that the solid waste falling into the bottom of the inner lining layer 202 is fully burned, and the ashes after combustion slide toward the rotary kiln 8 under the disturbance of the combustion airflow.

[0018] A primary sealing device is installed between the combustion kiln 2 and the rotary kiln 8, and the primary sealing device includes a sealing sleeve 9 installed between the combustion kiln 2 and the rotary kiln 8. The sealing sleeve 9 is mounted outside the combustion kiln 2, and a sealing ring 902 is installed in the sealing sleeve 9. In this embodiment, due to the relative rotation between the combustion kiln 2 and the rotary kiln 8, a gap needs to be reserved between the combustion kiln 2 and the rotary kiln 8 to reduce the friction between the combustion kiln 2 and the rotary kiln 8. A sealing adjustment device is also installed between the sealing sleeve 9 and the sealing ring 902. The sealing ring 902 is made of an elastic plate, specifically a stainless steel plate with a thickness of 3 mm, and has good elasticity and corrosion resistance. The sealing adjustment device includes a retaining ring 901 fixed to the edge of the sealing sleeve 9, and an adjusting rod 903 connected to the sealing sleeve 9 is fixed in the middle position of the sealing ring 902. The adjusting rod 903 extends outward to the outside of the sealing sleeve 9 and is connected to an adjusting ring 904. The adjusting rod 903 is a screw, and the adjusting ring 904 is a nut. 9 is made of a steel plate with a thickness of 6 mm. The lower end of the sealing sleeve 9 is fixed to the frame 1. The retaining ring 901 is formed by bending threaded steel, thereby improving the structural strength of the sealing sleeve 9. The width of the sealing ring 902 is twice the width of the sealing sleeve 9, thereby extending the sealing ring 902 to the outside of the sealing sleeve 9. The middle position of the sealing ring 902 is made close to the sealing sleeve 9 by adjusting the rod 903. Correspondingly, under the action of the retaining ring 901, the outer end of the sealing ring 902 is close to the combustion kiln 2 and the rotary kiln 8, thereby forming a seal. In order to improve the sealing effect, a vulcanized rubber layer can also be fixed on the edge of the sealing ring 902, and the rubber layer cooperates with the corresponding combustion kiln 2 and rotary kiln 8. The structure is simple and easy to adjust. It is found in the process of use that due to the wear of the rotary support device of the rotary kiln 8, the rotary kiln 8 will shift downward. When smoke leakage is found, the sealing ring 902 can be adjusted, which is convenient for operation. The rotary support device can be maintained after multiple adjustments.

[0019] The rotary kiln 8 has a two-stage pushing structure. The rotary kiln 8 is connected to a rotary support device and a rotary drive device. Specifically, the rotary kiln 8 includes a steel shell 801, which is connected to the rotary support device and the rotary drive device. The two-stage pushing device includes an inner lining layer 802 fixed in the steel shell. The inner lining layer 802 is also a prefabricated refractory material. The thickness of the inner lining layer 802 gradually decreases from the feed end to the discharge end, so that the ash can be pushed backward while ensuring the complete combustion of the solid waste. Since the thickness of the inner lining layer 802 at the front end is thicker, heat storage can be better performed. In the rotary kiln 8, the disturbance effect of the combustion airflow on the solid waste is weakened, and the solid waste has more contact with the rotary kiln 8. The heat storage of the inner lining layer 802 can promote the combustion of the solid waste. The rotary support device includes a plurality of sets of rotary support wheels 10 installed on the frame 1. The steel shell 801 is connected to the rotary support device and the rotary drive device. The two-stage pushing device includes an inner lining layer 802 fixed in the steel shell. The inner lining layer 802 is also a prefabricated refractory material. The thickness of the inner lining layer 802 gradually decreases from the feed end to the discharge end, so that the ash can be pushed backward while ensuring the complete combustion of the solid waste. Moreover, since the thickness of the inner lining layer 802 at the front end is thicker, heat storage can be better performed. In the rotary kiln 8, the disturbance effect of the combustion airflow on the solid waste is weakened, and the solid waste has more contact with the rotary kiln 8. The heat storage of the inner lining layer 802 can promote the combustion of the solid waste. A wear-resistant ring matched with the rotary support wheel 10 is fixed on 801, and the wear-resistant ring is a steel ring. The rotary drive device includes a reduction motor 13 installed on the frame 1, and the output end of the reduction motor 13 is connected to the rotary drive wheel. A rotary driven wheel 11 matched with the rotary drive wheel is fixed on the steel shell 801. The rotary drive wheel and the rotary driven wheel 11 are both gears, thereby ensuring the stable rotation of the rotary kiln 8. In this embodiment, the feed auger 4 is connected to the auger drive wheel 12, and the auger drive wheel 12 is connected to the rotary impulse wheel through the transition wheel 20. No additional drive source is required. The transition wheel 20 is connected to the feed auger 4 through the transition wheel frame 25. The rotation speed of the feed auger 4 is controlled by selecting the number of auger drive wheels 12. A support frame (not shown in the figure) is also installed between the end of the feed auger 4 and the frame 1 to improve the stability of the feed auger 4.

[0020] A transition kiln 15 is connected to the end of the rotary kiln 8. The transition kiln 15 is fixed to the frame 1. The transition kiln 15 is connected to a ash cleaning device. The ash cleaning device includes an ash discharge channel 16 processed at the lower end of the transition kiln 15. The solid waste is fully burned in the combustion kiln 2 and the rotary kiln 8. When entering the transition kiln 15, the flue gas is located in the upper layer and the ash is located in the lower layer. The ash in the lower layer falls from the ash discharge channel 16. After the flue gas enters the heat exchange equipment through the channel, it enters the flue gas desulfurization and denitrification equipment, and then is discharged to reduce environmental pollution and recycle heat energy. In this embodiment, a discharge pipe 21 is installed at the ash discharge channel 16. The discharge pipe 21 passes through the ash discharge channel 16 horizontally. The discharge pipe 21 is connected to the combustion-supporting gas inlet pipe, so that the combustion-supporting gas can be preheated. The vibration generated by the discharge pipe 21 can accelerate the falling of the ash. And the discharge pipe 21 reduces the flow area of ​​the ash outlet channel 16. During use, a valve can be installed at the lower end of the ash outlet channel 16, and the valve can be opened regularly to clean the ash. A secondary sealing device 14 is installed between the transition kiln 15 and the rotary kiln 8. The secondary sealing device 14 includes a sealing sleeve 2 1401 installed between the rotary kiln 8 and the transition kiln 15. The sealing sleeve is fixed to the frame 1. Since the temperature at the transition kiln 15 is reduced, the transition kiln 15 is made of a steel shell 3 1501. The steel shell 3 1501 is wrapped with an insulation layer 1502. The end of the insulation layer 1502 extends into the sealing sleeve 2 1401, and then is fixed by the sealing sleeve 2 1401. The gap between the insulation layer 1502 and the steel shell 2 801 is fixed, thereby improving the sealing effect between the steel shell 1 201 and the steel shell 2 801.

[0021] The high-efficiency solid waste incinerator provided in this embodiment continuously conveys the pre-dried and crushed solid waste to the feed hopper 5 through the conveyor belt, pushes it to the small-pitch auger 24 through the feed auger 4, and then is compressed, the gap is reduced, and a sealed isolation is formed, and it is continuously conveyed to the drop barrel 6 by the small-pitch auger 24, dispersed when passing through the dispersion structure, and then falls into the combustion kiln 2 and is ignited by the flame of the burner 3. Due to the effect of the dispersion structure, the solid waste does not gather and fall, and through the disturbance of the combustion airflow, the solid waste can move to the rotary kiln 8 in the combustion kiln 2, and part of the solid waste falls on the inner lining layer 202, and under the disturbance of gravity and the combustion airflow, it moves to the rotary kiln 8. The rotary kiln 8 slides to avoid accumulation in the combustion kiln 2. The solid waste in combustion enters the rotary kiln 8. In the rotary kiln 8, the disturbance effect of the combustion airflow on the solid waste is weakened, and the solid waste has more contact with the rotary kiln 8. The heat storage of the lining layer 2 802 can promote the combustion of the solid waste. After the solid waste is burned in the combustion kiln 2 and the rotary kiln 8, it enters the transition kiln 15. When entering the transition kiln 15, the flue gas is located in the upper layer and the ash is located in the lower layer. The ash in the lower layer falls from the ash outlet channel 16. After the flue gas enters the heat exchange equipment through the channel, it enters the flue gas desulfurization and denitrification equipment, and then is discharged to reduce environmental pollution. Heat energy can also be recycled and used in power plants.

[0022] The high-efficiency solid waste incinerator provided in this embodiment can also be used for cement production. When used for cement production, raw cement meal is fed into the feed auger 4, and the cement clinker is discharged through the ash discharge channel 16. The speed of the reduction motor is controlled to control the calcination time of the raw cement meal.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
