Technical Field
[0001] This application relates to the technical field of solid waste combustion equipment, and in particular to a gas guiding structure for improving the combustion efficiency of solid waste. Background Technology
[0002] With the increasing population, the amount of various types of household waste generated by people's lives has also risen sharply, among which non-recyclable waste accounts for the majority. Landfilling and incineration of solid waste pose serious environmental problems such as groundwater and air pollution. Pyrolysis gasification is a globally recognized technological development direction. However, most of the pyrolysis gasification equipment currently in use is derived from coal gasification and biomass gasification equipment.
[0003] The existing announcement number is CN206430135U, entitled "A Solid Waste Pyrolysis Gasification Device," which includes a gasifier body, a heating chamber, an oxidation zone, a reduction zone, a dry distillation zone, and a drying zone. The gasifier body, arranged sequentially from bottom to top, includes a slag collection chamber, a heating chamber, an oxidation zone, a reduction zone, a dry distillation zone, and a drying zone. An internal crushing device pulverizes the waste, making it finer for easier combustion and improved efficiency. The installed heat-conducting plates rapidly enhance heat conduction, allowing for quick temperature increases, saving time, and ensuring uniform heating for easy temperature control. As the flue gas moves upward, it heats the water in the water jacket, absorbing heat from the flue gas and reducing heat loss. The vibrating mesh not only spreads the waste evenly for easy ignition and combustion but also shakes the generated slag into the slag collection chamber at the bottom for thorough and unified treatment, ensuring complete slag removal without obstructing internal oxygen flow.
[0004] Regarding the aforementioned technologies, the inventors discovered that the furnace body used for burning solid waste uses a fan to introduce external air into the furnace body. However, the furnace body has only one air supply pipe. As solid waste accumulates on the grate, the amount of air received by solid waste of different thicknesses varies when air flows upward through a single air inlet, thus affecting the combustion efficiency and effect of solid waste on the grate. Utility Model Content
[0005] In order to overcome the problem that existing furnaces have only one air inlet, but solid waste accumulates on the grate, and the amount of air received by different layers of solid waste varies when air flows upward through a single air inlet, thus affecting the combustion efficiency and effect of solid waste on the grate, this application provides a gas guiding structure to improve the combustion efficiency of solid waste.
[0006] The gas guiding structure for improving the combustion efficiency of solid waste provided in this application adopts the following technical solution:
[0007] A gas guiding structure for improving the combustion efficiency of solid waste includes a combustion furnace body, a first air inlet, and a second air inlet. Multiple sliding grooves are horizontally and vertically perforated at the bottom of the outer vertical end face of the combustion furnace body, and a high-pressure air pump is fixedly connected to the bottom of the combustion furnace body. The first air inlet is located inside the combustion furnace body, and the second air inlet is located inside the combustion furnace body below the first air inlet. The first air inlet includes a perforated plate, which is horizontally fixed to the inner wall of the combustion furnace body. Multiple diversion pipes are horizontally arranged below the perforated plate. A gas box is fixed to the outer wall of the combustion furnace body, and the gas box is connected and fixed to one end of the multiple diversion pipes. Multiple air inlet pipes are horizontally connected and fixed to the other end face of the gas box, and an air pump is fixedly connected to each of the multiple air inlet pipes. Multiple mesh rods are horizontally and vertically connected and fixed to the outer wall of the diversion pipes, and the multiple mesh rods are arranged upwards through the perforated plate.
[0008] By adopting the above technical solution, solid waste is added to the combustion furnace body during use. The solid waste falls onto the perforated plate. In order to ensure the uniformity of combustion of the solid waste accumulated on the perforated plate, it is necessary to supply air to different layers of solid waste on the perforated plate. According to the oxygen consumption of the solid waste, the appropriate number of air pumps on the air inlet pipes are started to drive the external air into the air box. The air is then dispersed and guided into the combustion furnace body through multiple distribution pipes. Then, the air in the distribution pipes is vertically dispersed and discharged through the mesh rods. The air evenly contacts the solid waste accumulated at different depths for combustion. Thus, the solid waste accumulates on the perforated plate. Multiple mesh rods are set at different positions of the solid waste. When the air flows upward, the solid waste of different thicknesses can all receive air, thereby ensuring the combustion efficiency and effect of solid waste on the grate.
[0009] Optionally, a mesh cylinder is vertically fitted on the outer side of the mesh pole, and the upper side of the inner wall of the mesh cylinder is provided with internal threads.
[0010] By adopting the above technical solution, the setting of the mesh cylinder is used to prevent solid waste from clogging the air outlet of the mesh pole and affecting the air discharge efficiency. At the same time, the internal thread set on the upper side of the inner wall of the mesh cylinder is used for assembly on the mesh pole.
[0011] Optionally, a screw seat is fixed to the top of the mesh pole, and the screw seat is assembled and connected to the internal thread of the mesh cylinder.
[0012] By adopting the above technical solution, the screw seat fixed at the top of the mesh pole is assembled and connected with the internal thread of the mesh cylinder, which facilitates the assembly of the mesh cylinder on the mesh pole.
[0013] Optionally, a mesh box is connected and fixed to the end of the air intake pipe, and a mesh sheet is fixed through the other vertical end face of the mesh box.
[0014] By adopting the above technical solution, the air intake end of the air intake pipe is connected to a fixed mesh box for filtering air and removing impurities from the air. A mesh sheet is fixed on the outside of the mesh box for filtering and removing impurities from the air.
[0015] Optionally, a filter frame is vertically slidably assembled on the mesh box, and the inside of the filter frame is filled with filter cotton.
[0016] By adopting the above technical solution, a filter frame is vertically slidably inserted into the middle mesh box, and the filter cotton in the filter frame filters out impurities entering the air.
[0017] Optionally, the second air intake component includes an orifice plate, which is horizontally arranged below multiple diversion pipes and fixed to the inner wall of the combustion furnace body. Multiple blocking plates are horizontally arranged below the orifice plate.
[0018] By adopting the above technical solution, the orifice plate is used to discharge solid waste impurities. At the same time, the external air flows upward with the orifice plate. The number of air holes on the orifice plate is vertically opened by the blocking plate, and the amount of air flowing upward with the high-pressure air pump is controlled to control the amount of air entering and contacting the solid waste.
[0019] Optionally, a slide block is fixed to one end of the blocking plate, and the slide block is vertically slidably assembled in the slide groove. Multiple blocking blocks are vertically fixed on the top surface of the blocking plate, and the multiple blocking blocks on the blocking plate are inserted into the orifice plate one by one.
[0020] By adopting the above technical solution, when the blocking plate is opened during use, the slide at one end of the blocking plate slides vertically in the slide groove, causing the blocking block on the blocking plate to be pulled out of the orifice plate, thereby controlling the amount of air used for guiding the upward flow.
[0021] Optionally, multiple hydraulic rods are fixed horizontally and vertically on the outer wall of the combustion furnace body, and the output ends of the multiple hydraulic rods are fixed one-to-one on the slides at one end of multiple blocking plates.
[0022] By adopting the above technical solution, during use, the hydraulic rod pushes the slide block at one end of the block plate to slide vertically in the slide groove, and the block block on the moving block plate is pulled out of the orifice plate, which makes it easier to control the amount of air used for guiding the upward flow.
[0023] In summary, this application includes at least one of the following beneficial technical effects: During use, solid waste is added to the combustion furnace body and falls onto the perforated plate. To ensure the uniformity of combustion of the solid waste accumulated on the perforated plate, it is necessary to supply air to different layers of solid waste on the perforated plate. Based on the oxygen consumption of the burning solid waste, an appropriate number of air pumps on the air inlet pipes are activated, driving external air into the air box. The air is then dispersed and guided into the combustion furnace body through multiple distribution pipes. The air in the distribution pipes is then vertically dispersed and discharged through the mesh rods. The air uniformly contacts the solid waste accumulated at different depths for combustion, thus ensuring the solid waste accumulates on the perforated plate. Multiple mesh rods are set at different positions on the solid waste, allowing air to flow upwards, ensuring that solid waste of different thicknesses can receive air, thereby guaranteeing the combustion efficiency and effect of the solid waste on the grate.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.
[0031] This application discloses a gas guiding structure for improving the combustion efficiency of solid waste. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A gas guiding structure for improving the combustion efficiency of solid waste includes a combustion furnace body 1, a first air inlet 2, and a second air inlet 3. Multiple sliding grooves 11 are horizontally and vertically penetrating the bottom of the outer vertical end face of the combustion furnace body 1, and a high-pressure air pump 12 is fixedly connected to the bottom of the combustion furnace body 1. The first air inlet 2 is disposed inside the combustion furnace body 1. The second air inlet 3 is located inside the combustion furnace body 1, below the first air inlet 2. The first air inlet 2 includes a mesh plate 21, which is horizontally fixed on the inner wall of the combustion furnace body 1. Multiple diversion pipes 27 are horizontally arranged below the mesh plate 21. An air box 22 is fixed on the outer wall of the combustion furnace body 1. The air box 22 is connected and fixed to one end of the multiple diversion pipes 27. Multiple air inlet pipes 23 are horizontally connected and fixed on the other end face of the air box 22. An air pump 24 is connected and fixed on each of the multiple air inlet pipes 23. Multiple mesh rods 28 are horizontally and vertically connected and fixed on the outer wall of the diversion pipes 27. The multiple mesh rods 28 are arranged to penetrate the mesh plate 21 upwards.
[0032] By adopting the above technical solution, solid waste is added to the combustion furnace 1 during use, and the solid waste falls onto the perforated plate 21. In order to ensure the uniformity of combustion of the solid waste accumulated on the perforated plate 21, it is necessary to supply air to different layers of solid waste on the perforated plate 21. According to the oxygen consumption of the solid waste, the air pumps 24 on the appropriate number of air inlet pipes 23 are started, which drive the external air into the air box 22. The air is dispersed and guided to the combustion furnace 1 through multiple diversion pipes 27. Then, the air in the diversion pipes 27 is vertically dispersed and discharged through the mesh rods 287. The air evenly contacts the solid waste accumulated at different depths for gas supply and combustion. Thus, the solid waste is accumulated on the perforated plate 21. Multiple mesh rods 287 are set at different positions of the solid waste. When the air flows upward, the solid waste of different thicknesses can all receive air, thereby ensuring the combustion efficiency and effect of solid waste on the grate.
[0033] Reference Figure 3 and Figure 4 A mesh cylinder 29 is vertically fitted onto the outer side of the mesh rod 28, and an internal thread 291 is formed on the upper side of the inner wall of the mesh cylinder 29. The mesh cylinder 29 is used to prevent solid waste from clogging the air outlet of the mesh rod 28, thus affecting air discharge efficiency. Simultaneously, the internal thread 291 on the upper side of the inner wall of the mesh cylinder 29 is used for assembly onto the mesh rod 28. A screw seat 281 is fixed to the top of the mesh rod 28, and the screw seat 281 is assembled and connected to the internal thread 291 of the mesh cylinder 29. The assembly and connection of the screw seat 281 fixed to the top of the mesh rod 28 with the internal thread 291 of the mesh cylinder 29 facilitates the assembly of the mesh cylinder 29 onto the mesh rod 28.
[0034] Reference Figure 3 and Figure 4 The intake pipe 23 is connected to and fixedly connected to a mesh box 25, and a mesh sheet 251 is fixedly connected through the other vertical end face of the mesh box 25. The intake end of the intake pipe 23 is connected to and fixedly connected to the mesh box 25 for filtering air and removing impurities from the air. The mesh sheet 251 is fixedly connected to the outside of the mesh box 25 for filtering and removing impurities from the air. A filter frame 26 is vertically slidably assembled on the mesh box 25, and the inside of the filter frame 26 is filled with filter cotton 261. In use, the filter frame 26 is vertically slidably inserted into the mesh box 25, and the filter cotton 261 in the filter frame 26 filters and removes impurities from the incoming air.
[0035] Reference Figure 3 and Figure 4The second air inlet component 3 includes an orifice plate 31, which is horizontally positioned below multiple branch pipes 27 and fixed to the inner wall of the combustion furnace body 1. Multiple blocking plates 32 are horizontally positioned below the orifice plate 31. During use, the orifice plate 31 is used to discharge solid waste impurities. Simultaneously, the orifice plate 31 allows external air to flow upwards. The number of air holes vertically opened on the orifice plate 31 by the blocking plates 32, in conjunction with the amount of air guided upwards by the high-pressure air pump 12, controls the amount of air entering and contacting the solid waste. A slide block 33 is fixed to one end of the blocking plate 32 and is vertically slidably assembled in a slide groove 11. Multiple blocking blocks are vertically fixed to the top surface of the blocking plate 32, and these blocks are inserted into the orifice plate 31 one-to-one. When the blocking plate 32 is opened during use, the slide block 33 at one end of the blocking plate 32 slides vertically in the slide groove 11, causing the blocking blocks on the blocking plate 32 to be pulled out of the orifice plate 31, thereby controlling the amount of air used for upward airflow. Multiple hydraulic rods 34 are fixed horizontally and vertically on the outer wall of the combustion furnace body 1, and the output ends of the multiple hydraulic rods 34 are fixed one-to-one on the slide block 33 at one end of the multiple blocking plates 32. In use, the hydraulic rods 34 are activated to push the slide block 33 at one end of the blocking plate 32 to slide vertically in the slide groove 11, and the blocking block on the moving blocking plate 32 is pulled out of the orifice plate 31, which makes it easier to control the amount of gas used for upward flow.
[0036] The implementation principle of a gas guiding structure for improving the combustion efficiency of solid waste in this application embodiment is as follows: During use, solid waste is added to the combustion furnace body 1 and falls onto the perforated plate 21. In order to ensure the uniformity of combustion of the solid waste accumulated on the perforated plate 21, it is necessary to supply gas to different layers of solid waste on the perforated plate 21. According to the oxygen consumption of the solid waste, the appropriate number of air pumps 24 on the air inlet pipes 23 are selected and started, which drives the external air into the air box 22. The air is dispersed and guided to the combustion furnace body 1 through multiple diversion pipes 27. Then, the air in the diversion pipes 27 is vertically dispersed and discharged through the mesh rod 287. The air evenly contacts the solid waste accumulated at different depths for gas supply and combustion, so that the solid waste accumulates on the perforated plate 21.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
