Description

Technical Field

[0001] This invention relates to the field of incinerator technology, and more specifically to a hazardous solid waste incineration device. Background Technology

[0002] Biomass combustion boilers utilize renewable fuels such as biomass pellets and wood blocks for combustion, generating heat energy and transferring it to provide heating. During operation, biomass combustion boilers generate hazardous solid waste, which is then further incinerated in a vertical incinerator. During incineration, the resulting flue gas, mixed with particulate matter remaining from the waste combustion, rises within the incinerator and is discharged through pipes at the top to a heat exchanger / cooling furnace on the side of the incinerator for cooling. The residues and some particulate matter from the waste combustion, upon entering the heat exchanger / cooling furnace and contacting the heat exchange walls, condense and adhere to them. Prolonged introduction of mixed flue gas into the furnace results in a layer of foreign matter deposits covering the heat exchanger walls. During continuous operation, the flue gas that enters the furnace first is propelled downwards by the following flue gas, causing it to linger in different areas of the furnace. This results in prolonged contact between the flue gas and the heat exchange walls and the deposit layer covering their surfaces. This deposit layer accumulates and thickens, forming large-scale caking on the heat exchange wall surface. This affects the flow velocity of the flue gas within the furnace and reduces the heat exchange efficiency of the heat exchange walls. The thickened deposit layer also hinders heat dissipation in the areas covering the heat exchange walls, preventing them from operating safely for extended periods and ultimately impacting the normal operation of the incineration equipment. Summary of the Invention

[0003] To overcome the aforementioned deficiencies of the prior art, this invention provides a hazardous solid waste incineration device. An angled guide shell allows mixed flue gas to enter, while an inclined release shell and guide plate release external gas obliquely into the angled guide shell, impacting the mixed flue gas as it enters the heat exchange furnace, thus increasing the rate at which the flue gas enters the furnace. Two opposing air outlets release a portion of the gas towards the furnace wall, and a trapezoidal baffle blocks the gas released towards the furnace wall between the two air outlets, effectively impacting different areas of the furnace wall and preventing the formation of a large-scale deposit layer covering the furnace wall. A guide box guides a portion of the gas into the opposing, staggered downward and upward inclined release outlets, subsequently releasing gas upward and downward from opposing positions, respectively. This propels the flue gas to diffuse at different heights within the furnace, allowing the flue gas and airflow to converge and circulate, contacting the furnace wall at corresponding heights. This improves the blowing effect on deposits adhering to the furnace wall and enhances heat exchange efficiency, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A hazardous solid waste incineration device includes an incinerator body and a heat exchanger body fixed at the outlet end of the incinerator body. The heat exchanger body has a guided release module inside, which includes an angled guide shell, a first gas supply component, and an inclined release shell. The angled guide shell is fixed in front of the outlet end of the incinerator body, the first gas supply component is fixed at the top of the heat exchanger body, and the inclined release shell is secured inside the angled guide shell by the first gas supply component, allowing the inclined release gas to mix with flue gas and enter the heat exchanger body. The heat exchanger body also has four soot blowing modules arranged from top to bottom. Each soot blowing module includes a guide box, a blowing exhaust, and an inclined downward release exhaust. The furnace has two upward-sloping release vents, which are symmetrically fixed inside the heat exchanger body via an air guide box. The downward-sloping release vent and the upward-sloping release vent are respectively fixed inside the two air vents. A second air supply component is fixedly connected to the top of the heat exchanger body, guiding the gas into the soot blowing module. Gas is released into the heat exchanger body by the air vents, the downward-sloping release vent, and the upward-sloping release vent. Four trapezoidal baffles corresponding to the soot blowing module are fixedly connected inside the heat exchanger body. These baffles are located between corresponding air vents to block and guide the released gas from impacting the inner wall of the heat exchanger body.

[0006] Furthermore, the top of the angular guide shell is fixedly connected to the inner wall of the top of the heat exchange furnace body, and the lateral inlet end of the angular guide shell is aligned with and connected to the outlet end of the incinerator body.

[0007] Furthermore, the inclined release shell is fixedly connected to the output end of the first air supply component, and the inclined release shell is engaged with the top of the angular guide shell.

[0008] Furthermore, the inner wall of the angular guide shell has an arc-shaped bevel, the bottom opening of the inclined release shell faces the arc-shaped bevel, and a guide plate is fixedly connected to the bottom of the inclined release shell.

[0009] Furthermore, the air guide box is fixedly connected to the inner wall of the heat exchange furnace, and the two air blowers are respectively fixedly connected to the bottom of the two long sides of the air guide box.

[0010] Furthermore, the top ends of both the downward-sloping release outlet and the upward-sloping release outlet are fixedly connected to the bottom of the air guide box. The release ports on the downward-sloping release outlet and the upward-sloping release outlet are staggered, with the release port on the upward-sloping release outlet located below the corresponding release port on the downward-sloping release outlet.

[0011] Furthermore, the outer walls of the two air guide boxes, which are positioned vertically, are fixedly connected to an outer connecting box. The outer connecting box is located on the outside of the heat exchange furnace body and is fixedly connected to the outer wall of the heat exchange furnace body.

[0012] Furthermore, the output end of the second gas supply component is fixedly connected to a combination frame, which is fixedly connected between the inner wall of the heat exchange furnace and the outer wall of the angular guide shell, and the output end of the combination frame is fixedly connected to the top of the uppermost gas guide box.

[0013] Furthermore, the top of the trapezoidal baffle is flush with the bottom of the air outlet, and through slots are provided on all four sides of the trapezoidal baffle. A fixing rod is fixedly connected to the outer wall of the trapezoidal baffle, and the fixing rod is screwed and fixed inside the heat exchange furnace body.

[0014] Furthermore, a combustion rack is fixedly connected inside the incinerator body.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention, by setting a guide release module, connects the top inlet of the heat exchange furnace body to the top outlet of the incinerator body. When the mixed flue gas is discharged from the top outlet of the incinerator body to the heat exchange furnace body, the angular guide shell allows the mixed flue gas to enter. The external gas introduced by the first gas supply component is released obliquely into the angular guide shell by the inclined release shell and guide plate, so as to effectively impact the mixed flue gas to enter the heat exchange furnace body and increase the rate at which the flue gas enters the heat exchange furnace body.

[0017] 2. In this invention, flue gas enters downwards into the inner area of ​​the trapezoidal baffle and the soot blowing module. External gas is introduced into the gas guide box by the second gas supply component. Two opposing gas blowing outlets release some gas towards the furnace wall to impact and treat the deposits on the furnace wall. The trapezoidal baffle blocks the gas released towards the furnace wall between the two gas blowing outlets, extending the distance the gas travels downwards on the furnace wall. Simultaneously, it allows the gas to circulate within the range between the furnace wall and the trapezoidal baffle, effectively impacting different areas of the furnace wall and preventing the formation of a large-scale deposit layer covering the furnace wall. The gas guide box also guides some gas into the opposing, staggered downward and upward release outlets, which then release gas upwards and downwards from opposite positions. This promotes the diffusion of flue gas at different heights within the furnace, allowing the flue gas and airflow to converge and circulate, contacting the furnace wall at corresponding heights. This optimizes the flow of flue gas within the furnace, improves the blowing effect on the deposits on the furnace wall and the heat exchange efficiency, and ensures the normal operation of the incineration equipment.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Specific mechanical structures of the present invention will be described in conjunction with the following references. Figures 1 to 6 The detailed description of the structure will be clearly presented. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0027] Please see Figures 1-6In this embodiment of the invention, a hazardous solid waste incineration device includes an incinerator body 1 and a heat exchanger body 2 fixed at the outlet end of the incinerator body 1. The heat exchanger body 2 is equipped with a guide release module 3, which includes an angular guide shell 31, a first gas supply component 32, and an inclined release shell 33. The angular guide shell 31 is fixed in front of the outlet end of the incinerator body 1, the first gas supply component 32 is fixed at the top of the heat exchanger body 2, and the inclined release shell 33 is secured inside the angular guide shell 31 by the first gas supply component 32, allowing the inclined release gas to mix with the flue gas and enter the heat exchanger body 2. The heat exchanger body 2 is equipped with four soot blowing modules 4 distributed from top to bottom. Each soot blowing module 4 includes a guide box 41 and a blower 4. 2. There are two air-blowing outlets 42, one downward-facing release outlet 43 and the other upward-facing release outlet 44. The two air-blowing outlets 42 are symmetrically fixed inside the heat exchange furnace body 2 through the air guide box 41. The downward-facing release outlet 43 and the upward-facing release outlet 44 are respectively fixed inside the two air-blowing outlets 42. The top of the heat exchange furnace body 2 is fixedly connected to the second air supply component 5. The second air supply component 5 guides the gas into the soot blowing module 4, and the gas is released into the heat exchange furnace body 2 by the air-blowing outlets 42, the downward-facing release outlet 43 and the upward-facing release outlet 44. Four trapezoidal baffles 6 corresponding to the soot blowing module 4 are fixedly connected inside the heat exchange furnace body 2. The trapezoidal baffles 6 are located between the corresponding two air-blowing outlets 42 to block and guide the released gas to impact the inner wall of the heat exchange furnace body 2.

[0028] The incinerator body 1 and the heat exchanger body 2 located on the side stand in the working area. An incinerator rack 11 is fixedly connected inside the incinerator body 1. When the furnace door of the incinerator body 1 is opened, waste is fed onto the incinerator rack 11. After closing the furnace door, the incinerator body 1 is started to incinerate the waste. The top inlet of the heat exchanger body 2 connects to the top outlet of the incinerator body 1, allowing the flue gas generated from waste incineration to enter the heat exchanger body 2 from the top outlet of the incinerator body 1, where the heat exchanger body 2 guides and cools the flue gas.

[0029] The guide release module 3 is located inside the heat exchange furnace body 2. The guide release module 3 consists of an angular guide shell 31, a first gas supply component 32, and an inclined release shell 33. The top of the angular guide shell 31 is fixedly connected to the inner wall of the top of the heat exchange furnace body 2. The transverse inlet end of the angular guide shell 31 is aligned with and connected to the outlet end of the incinerator body 1, stably connecting the angular guide shell 31 in front of the outlet end of the incinerator body 1 to guide the flue gas drawn from the incinerator body 1 into the interior of the angular guide shell 31. The first gas supply component 32 is fixedly connected to the top of the heat exchange furnace body 2. The inclined release shell 33 is fixedly connected to the output end of the first gas supply component 32, engaging with the top of the angular guide shell 31, positioning the inclined release shell 33 between the transverse inlet end of the angular guide shell 31 and the outlet end of the incinerator body 1. When the first gas supply component 32 is activated, it can release external gas at an angle through the inclined release shell 33 into the interior of the angular guide shell 31 to mix with the flue gas discharged from the incinerator body 1. The inner wall of the angular guide shell 31 has an arc-shaped guide angle 311, and the bottom opening of the inclined release shell 33 faces the arc-shaped guide angle 311, which can avoid dead angles in flue gas flow and allow the flue gas to smoothly enter the interior of the heat exchange furnace body 2 along the angular guide shell 31. A guide plate 331 is fixedly connected to the bottom of the inclined release shell 33. An inclined guide area is formed between the bottom outlet of the inclined release shell 33 and the guide plate 331. After the mixed flue gas is discharged into the interior of the angular guide shell 31 from the top outlet of the incinerator body 1, the inclined release shell 33 and the guide plate 331 can cooperate to release the external gas introduced by the first gas supply component 32 at an angle into the interior of the angular guide shell 31, so as to effectively impact the mixed flue gas to enter the interior of the heat exchange furnace body 2 and increase the rate at which the flue gas enters the heat exchange furnace body 2.

[0030] Four soot blowing modules 4 are installed inside the heat exchanger body 2, vertically distributed from top to bottom. Each soot blowing module 4 consists of an air guide box 41, air outlets 42, downward-sloping release outlets 43, and upward-sloping release outlets 44. The air guide box 41 is fixedly connected to the inner wall of the heat exchanger body 2. Two air outlets 42 are fixedly connected to the bottom of the two long sides of the air guide box 41, symmetrically fixing the two air outlets 42 inside the heat exchanger body 2. The tops of the downward-sloping release outlets 43 and 44 are fixedly connected to the bottom of the air guide box 41. The downward-sloping release outlets 43 and 44 are located inside the two air outlets 42, ensuring that they do not obstruct each other. The second air supply component 5 is fixed to the top of the heat exchange furnace body 2. The output end of the second air supply component 5 is fixedly connected to a combination frame 51. The combination frame 51 is fixedly connected between the inner wall of the heat exchange furnace body 2 and the outer wall of the angular guide shell 31, stably connecting the combination frame 51 inside the heat exchange furnace body 2. The output end of the combination frame 51 is fixedly connected to the top of the uppermost air guide box 41. The combination frame 51 connects the output end of the second air supply component 5 and the uppermost air guide box 41. When the second air supply component 5 is activated, external gas is guided into the uppermost soot blowing module 4, allowing the gas to flow inside the air guide box 41. The gas is then released into the heat exchange furnace body 2 through the air blowing outlet 42, the downward-sloping release outlet 43, and the upward-sloping release outlet 44, allowing the gas to mix with the flue gas and blow against the furnace wall inside the heat exchange furnace body 2. The outer walls of the two air guide boxes 41 located at the top and bottom are fixedly connected to the outer connecting box 45. The outer connecting box 45 is located outside the heat exchange furnace body 2 and is fixedly connected to the outer wall of the heat exchange furnace body 2. The two corresponding air guide boxes 41 are connected through the outer connecting box 45 to effectively connect the four vertically distributed air guide boxes 41, so that the four soot blowing modules 4 can effectively cover different height positions inside the furnace.

[0031] Four trapezoidal baffles 6 are installed inside the heat exchange furnace body 2, corresponding to four soot blowing modules 4. The top of the trapezoidal baffle 6 is flush with the bottom of the air blowing nozzle 42. A fixing rod 62 is fixedly connected to the outer wall of the trapezoidal baffle 6, extending to the outside of the heat exchange furnace body 2. The end of the fixing rod 62 extending to the outside of the heat exchange furnace body 2 is fixed with a nut, so that the trapezoidal baffle 6 is stably fixed inside the heat exchange furnace body 2 by the fixing rod 62, so as to effectively position the trapezoidal baffle 6 between the corresponding two air blowing nozzles 42. The flue gas released by the guide release module 3 enters downward into the inner area of ​​the trapezoidal baffle 6 and the soot blowing module 4. External gas is introduced into the air guide box 41 by the second air supply component 5. The two opposing air blowing nozzles 42 release part of the gas towards the furnace wall of the heat exchange furnace body 2. The gas moves downward along the furnace wall to impact and treat the adhering substances on the furnace wall. The trapezoidal baffle 6 blocks the gas released from the two air outlets 42 to the furnace wall, and guides the gas to flow between the furnace wall and the trapezoidal baffle 6. This can extend the distance that the gas blows downward on the furnace wall, and at the same time allow the gas to circulate within the range between the furnace wall and the trapezoidal baffle 6, so as to effectively impact different areas of the furnace wall being treated and avoid the formation of a large-scale deposit layer covering the furnace wall.

[0032] The gas in the gas guide box 41 flows through the upward and downward release outlets 44 and 43, guiding some of the gas into the interior of the opposing and staggered downward and upward release outlets 43 and 44. The release ports on the downward and upward release outlets 43 and 44 are staggered, with the release port on the upward release outlet 44 located below the corresponding release port on the downward release outlet 43. This allows the upward and downward release outlets 44 and 43 to release gas upward and downward from opposite positions, respectively. The released gas mixes with the flue gas in the furnace and simultaneously promotes the diffusion of the flue gas at different heights in the furnace. This allows the flue gas and airflow to converge and circulate, contacting the furnace wall at the corresponding height, optimizing the flow of the flue gas in the furnace, increasing the contact time between the flue gas and the furnace wall of the heat exchange furnace 2, and improving the heat exchange efficiency. The trapezoidal baffle 6 has through slots 61 on all four sides. The mixed flue gas, which is pushed, circulates in and out of the space between the trapezoidal baffle 6 and the furnace wall through the through slots 61. This ensures that the flue gas waste has sufficient residence time in the furnace wall area, allowing the blowing exhaust 42 to continuously blow and treat the adhering substances in the flue gas that are in contact with the furnace wall. This improves the blowing and treatment effect of the adhering substances on the furnace wall, avoids the formation of large-scale caking on the surface of the furnace wall of the heat exchange furnace body 2, and ensures the safe operation of the heat exchange furnace body 2 for a long time and the normal use of the incineration equipment.

[0033] The working principle of this invention is as follows: the furnace door of the incinerator body 1 is opened, the waste is put into the incineration rack 11, the furnace door is closed, and the incinerator body 1 is started to carry out the incineration operation of the waste. The flue gas generated by the incineration of waste flows from the top outlet of the incinerator body 1 to the heat exchange furnace body 2. The flue gas enters the interior of the angular guide shell 31. The first gas supply component 32 is activated, and external gas is released obliquely through the inclined release shell 33 into the interior of the angular guide shell 31. The gas mixes with the flue gas discharged from the incinerator body 1, allowing the flue gas to smoothly enter the interior of the heat exchange furnace body 2 along the angular guide shell 31. The second air supply unit 5 is activated, guiding external gas into the topmost soot blowing module 4. The gas flows inside the air guide box 41 and is released into the heat exchange furnace body 2 by the air blowing outlet 42, the downward-sloping release outlet 43, and the upward-sloping release outlet 44. The gas mixes with the flue gas and blows against the furnace wall inside the heat exchange furnace body 2. The gas diffuses inside the heat exchange furnace body 2 to contact the furnace wall for cooling. At the same time, the gas released by the air blowing outlet 42 moves downward along the furnace wall between the trapezoidal baffle 6 and the furnace wall to impact and treat the adhering substances on the furnace wall. The cooled flue gas is discharged from the bottom opening of the heat exchange furnace body 2 to continue flowing to the next stage for dust removal in the flue gas.
