Abstract
Description
Technical Field
[0001] The present invention relates to garbage disposal equipment, and particularly to an all-in-one small-sized garbage disposer. Background Art
[0002] The heterogeneous biomass pyrolysis gasification technology is a popular research field at present, because the treatment and resource utilization of domestic garbage, industrial waste, and agricultural and forestry waste included in the national environmental protection energy strategy all belong to this field.
[0003] In the prior art, garbage usually needs to be transported to a large garbage treatment plant for treatment, resulting in high transportation costs. To miniaturize garbage disposal equipment, reduce the floor area and construction cost of garbage disposal equipment, garbage disposers can be set up in areas with a large amount of garbage generated to achieve on-site garbage treatment. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide an all-in-one small-sized garbage disposer.
[0005] The technical solution of the present invention for solving the above technical problem is as follows: An all-in-one small-sized garbage disposer includes a feeding device, a box-type pyrolysis gasification furnace, a flue gas treatment box, an activated carbon adsorption box, and a smoking fan that are connected in sequence. The box-type pyrolysis gasification furnace, the flue gas treatment box, and the activated carbon adsorption box are arranged from bottom to top in sequence, and the feeding device is arranged on one side of the box-type pyrolysis gasification furnace.
[0006] The beneficial effects of the present invention are: The all-in-one small-sized garbage disposer of the present invention integrates feeding, pyrolysis, and flue gas treatment, and can realize the treatment of heterogeneous organic solid waste. Adopting a box-type structure, it has a compact structure and reasonable layout, achieving miniaturized and integrated design, with a small floor area, and is convenient for transportation and erection.
[0007] Based on the above technical solution, the present invention can be further improved as follows.
[0008] Further, the top wall of the box-type pyrolysis gasification furnace has a flue gas outlet, the bottom wall of the flue gas treatment box has a smoke inlet, and the smoke inlet and the flue gas outlet are arranged vertically aligned and directly connected.
[0009] The beneficial effect of adopting the above further solution is: Existing pyrolysis equipment and flue gas treatment equipment are both large-sized equipment, and a pipeline is required to connect them, resulting in a large floor area, and setting up a pipeline will generate wind resistance, which is not conducive to flue gas flow. By using the box-type pyrolysis gasification furnace and the flue gas treatment box of the present invention, the flue gas treatment box is arranged above the box-type pyrolysis gasification furnace, and the two can be directly connected through the corresponding flue gas outlet and smoke inlet, with a simple and compact structure and smooth flue gas flow.
[0010] Further, it further includes a spray water comprehensive treatment tank. The oil-contaminated hot water inlet of the spray water comprehensive treatment tank is communicated with the drain outlet of the flue gas treatment tank, and the spray water outlet of the spray water comprehensive treatment tank is communicated with the flue gas treatment tank.
[0011] The beneficial effect of adopting the above further scheme is that the all-in-one small garbage processor of the present invention can also realize the treatment and circulation of spray water, reducing waste water discharge.
[0012] Further, the spray water comprehensive treatment tank is arranged below the flue gas treatment tank.
[0013] The beneficial effect of adopting the above further scheme is that the structure is compact and the layout is reasonable.
[0014] Further, the spray water comprehensive treatment tank includes an oil-water separation device, a pressure filtration device and a heat exchange device arranged in the treatment tank body. The side wall of the treatment tank body has the oil-contaminated hot water inlet and the spray water outlet. The oil-contaminated hot water inlet is communicated with the oil-water separation device. The contaminated hot water outlet of the oil-water separation device is communicated with the inlet of the pressure filtration device. The outlet of the pressure filtration device is communicated with the heat medium inlet of the heat exchange device. The heat medium outlet of the heat exchange device is communicated with the spray water outlet.
[0015] The beneficial effect of adopting the above further scheme is that the flue gas spray water is separated into contaminated hot water and tar by the oil-water separation device. The contaminated hot water is filtered by the pressure filtration device to remove sludge, and then the contaminated hot water is cooled by the heat exchange device to obtain spray water that can be reused. The spray water comprehensive treatment tank is integrated in one tank body, with a compact structure, fast spray water treatment, and functions such as oil-water separation, particulate matter filtration, forced spray water heat exchange and cooling, so that the spray water can be comprehensively treated and recycled, realizing zero discharge of spray water.
[0016] Further, the feeding device includes a tubular housing, a chain conveyor and a pusher. One end of the housing has a feeding port, and the other end has a receiving port. One end of the housing near the receiving port has a convex section protruding upward, and the convex section is higher than the feeding port and the receiving port. The chain conveyor is fixedly arranged in the housing and is used to convey materials from the feeding port to the receiving port. The pusher is rotatably connected to the side wall of the receiving port and is used to push the materials out of the receiving port. The receiving port is communicated with the feeding port of the box-type pyrolysis gasification furnace.
[0017] The beneficial effects of adopting the above further solution are as follows: The organic solid waste without prior homogenization treatment is added onto the chain conveyor at the feeding port by a shovel (bucket) truck or manually. As the conveyor belt of the chain conveyor rotates, the garbage is conveyed obliquely upwards, and then pushed into the receiving port by a pusher for subsequent treatment. The feeding device of the present invention is suitable for small machinery (forklift) or manual feeding. The setting of the pusher can avoid the process interruption caused by tower bridging and the like during the feeding of non-homogeneous organic solid waste. The housing that is closed on all sides only includes the feeding port and the receiving port, and the receiving port is connected to the subsequent treatment equipment, so that the housing can prevent the odor from overflowing. The tubular housing serves as the drying section. Since the receiving port is connected to the box-type pyrolysis gasification furnace, the temperature in the box-type pyrolysis gasification furnace will cause the temperature in the housing to rise. The tubular structure is beneficial for heat preservation and enables it to have a preliminary drying function, which is beneficial for the subsequent treatment. The housing near the receiving port is in a shape that is higher in the middle and lower at both ends. Since hot air will rise under natural conditions, this structure can keep the hot air at the top of the housing, which is beneficial for heat preservation and preliminary drying of the material.
[0018] Further, the top of the convex section is communicated with the flue gas treatment box through a connecting pipe, and a blower is also provided on the connecting pipe. The blower pumps the gas in the feeding device into the secondary combustion chamber.
[0019] The beneficial effects of adopting the above further solution are as follows: The blower pumps the hot air in the feeding device into the secondary combustion chamber. This part of the hot air contains both a small amount of pyrolysis gas overflowing from the box-type pyrolysis gasification furnace and the air entering from the feeding port. After being introduced into the secondary combustion chamber, it can play a role in assisting combustion and burning the pollutants therein, avoiding the leakage of pollutants.
[0020] Further, the pusher includes a pressing block and a pressing driving mechanism. The lower side wall of the housing near the receiving port has a pressing port. The pressing block is rotatably connected to the side wall of the housing and is located in the pressing port. The pressing driving mechanism drives the pressing block to rotate; the pressing block has a pressing surface and a mating surface. The pressing surface is used to push the material out of the receiving port, and the mating surface abuts against the side wall of the pressing port during the rotation of the pressing block.
[0021] The beneficial effects of adopting the above further solution are as follows: The pressing block pushes the material to avoid the bridging phenomenon of the material in the feeding channel. During the rotation of the pressing block, that is, during the pressing process, the mating surface abuts against the side wall of the pressing port to prevent the material from leaking out of the pressing port.
[0022] Further, the box-type pyrolysis gasification furnace comprises a reaction kettle and a pyrolysis box body. The reaction kettle rotates horizontally and axially within the pyrolysis box body. The reaction kettle includes a reaction kettle body, a transition section, and a feed cylinder. The reaction kettle body is in a cylindrical shape with one end closed and the other end open. The other end of the reaction kettle body is fixedly connected or integrally formed and communicated with one end of the feed cylinder through the transition section. The diameter of the feed cylinder is smaller than that of the reaction kettle body. The other end of the feed cylinder passes through the pyrolysis box body and is communicated with the feeding device. The side wall of the reaction kettle body is provided with a discharge port, the bottom wall of the pyrolysis box body is provided with a slag discharge port, and the top of the pyrolysis box body is provided with a flue gas outlet. The flue gas outlet is communicated with the flue gas treatment box.
[0023] The beneficial effects of adopting the above further scheme are as follows: The heterogeneous biomass material can complete the feeding, charging, and pyrolysis processes with a box-type pyrolysis gasification furnace equipped with a bottle-shaped reaction kettle without pretreatment. Before the material is fed, there is no need to use a crusher. The diameter of the feed cylinder is smaller than that of the reaction kettle body, which is conducive to the accumulation of heat in the feed cylinder. The material just entering the reaction kettle can be preheated, and the pyrolysis efficiency is improved. Its principle is similar to the countercurrent pyrolysis in the prior art. The pyrolysis gas can be discharged from the discharge port and enter the space between the pyrolysis box body and the reaction kettle, and then be discharged from the flue gas outlet at the top of the pyrolysis box body to the flue gas treatment box. The pyrolysis gas can achieve the heat preservation of the reaction kettle, and the heat can be fully utilized. The box-type pyrolysis gasification furnace has a compact structure, high pyrolysis efficiency, does not require homogenization treatment of the material, and saves investment and operation costs.
[0024] Further, the flue gas treatment box includes a flue gas box body. The flue gas box body is divided into a secondary combustion chamber, a heat exchange area, a desulfurization and denitrification area, and a dust and mist removal area that are sequentially communicated through a partition board. The flue gas box body has a flue gas inlet and a smoke exhaust port. The secondary combustion chamber is communicated with the box-type pyrolysis gasification furnace through the flue gas inlet, and the dust and mist removal area is communicated with the inlet of the activated carbon adsorption box through the smoke exhaust port.
[0025] The beneficial effects of adopting the above further scheme are as follows: The flue gas treatment box ingeniously arranges tail gas treatment equipment such as a secondary combustion chamber for flue gas, a waste heat exchanger, wet desulfurization and denitrification, and wet electrostatic dust and mist removal in the box body, and highly integrates the waste heat utilization of flue gas and tail gas treatment in a box cabinet to achieve miniaturization and integration. This flue gas treatment box has the following advantages: ① No air duct connection is required, eliminating system air resistance and reducing pressure loss; ② Sharing the partition wall saves material investment; ③ Sharing refrigerant and cleaning medium improves efficiency; ④ Saving space; ⑤ Miniaturization and integration; ⑥ Providing a one-stop environmental protection treatment and energy utilization solution for raw flue gas (pyrolysis gas).

[0052] As a further solution of this embodiment, the spray water comprehensive treatment tank 6 is arranged below the flue gas treatment tank 3.
[0053] As a further solution of this embodiment, as Figures 11-13 shown, the spray water comprehensive treatment tank 6 includes an oil-water separation device 62, a pressure filtration device 64 and a heat exchange device arranged in the treatment tank body. The side wall of the treatment tank body has the oil-contaminated hot water inlet 61 and the spray water outlet. The oil-contaminated hot water inlet 61 is communicated with the oil-water separation device 62. The dirty hot water outlet of the oil-water separation device 62 is communicated with the inlet of the pressure filtration device 64. The outlet of the pressure filtration device 64 is communicated with the heat medium inlet of the heat exchange device. The heat medium outlet of the heat exchange device is communicated with the spray water outlet.
[0054] Preferably, the spray water outlet and the oil-contaminated hot water inlet 61 are arranged on the upper part of the side wall or the top wall of the treatment tank body.
[0055] Specifically, the oil-water separation device 62 can be an oil-water separation tank or an oil-water separation area separated by a partition in the box body. Water and oil are separated by natural sedimentation. The bottom of the oil-water separation area is communicated with the pressure filtration device 64, and the upper part of the oil-water separation area has a pipeline for discharging tar.
[0056] Specifically, the treatment tank body is a container.
[0057] As a further solution of this embodiment, it further includes a dirty hot water tank 63 and a dirty hot water pump 611. The dirty hot water outlet of the oil-water separation device 62, the dirty hot water tank 63, the dirty hot water pump 611 and the inlet of the pressure filtration device 64 are communicated in sequence.

[0061] As a further solution of this embodiment, it further includes an alkali solution tank 610, and the outlet of the alkali solution tank 610 is communicated with the clean cold water tank 67. The alkali solution in the spray water is consumed during the adsorption process, and the alkali solution tank 610 replenishes the alkali solution into the clean cold water tank 67, so that the clean cold water can be used as spray water to play the functions of dust reduction and adsorption.
[0062] Specifically, a switching valve is provided on the pipeline connecting the alkali solution tank 610 and the clean cold water tank 67, and the switching valve is electrically connected to the controller in the electric control box 7. The controller opens the switching valve at regular intervals to add a certain amount of alkali solution into the clean cold water tank 67, and then closes the switching valve. Ensure that the alkali solution content in the spray water is sufficient so that the spray water can be recycled. It should be noted that the controller controls the opening and closing of the switching valve, and those skilled in the art can implement it using existing technologies. For the sake of concise expression, it will not be elaborated here.
[0063] Specifically, the dirty hot water tank 63, the clean hot water tank 65, the clean cold water tank 67, the tar tank 68 and the alkali solution tank 610 are all independent boxes, or are all areas separated by partitions in the processing box body for accommodating corresponding liquids.
[0064] As a further solution of this embodiment, the heat exchange device includes a plate heat exchanger 66 and a cooling tower 69. The outlet of the pressure filtration device 64 is communicated with the hot medium inlet of the plate heat exchanger 66. The hot medium outlet of the plate heat exchanger 66 is communicated with the spray water outlet of the processing box body. The refrigerant outlet of the plate heat exchanger 66 is connected to the inlet of the cooling tower 69, and the outlet of the cooling tower 69 is connected to the refrigerant inlet of the plate heat exchanger 66. The cooling tower 69 cools the refrigerant, and the refrigerant circulates and exchanges heat in the plate heat exchanger 66 and the cooling tower 69.
[0065] Specifically, the cooling tower 69 adopts a small cooling tower, which is small in volume and can be integrated in the processing box body.
[0066] As a further solution of this embodiment, as Figures 11-13As shown in the figure, the oil-water separation device 62 is located above one end of the treatment tank body. The dirty hot water tank 63, the clean hot water tank 65, and the clean cold water tank 67 are sequentially arranged below one end of the treatment tank body. The tar tank 68 and the lye tank 610 are arranged at one end of the treatment tank body and are located between the oil-water separation device 62 and the clean cold water tank 67. The filter press device 64 and the plate heat exchanger 66 are arranged at the other end of the treatment tank body. The internal layout is reasonable and the structure is compact, and it can be integrated into a container to achieve miniaturization and integration.
[0067] As a further solution of this embodiment, the dirty hot water pump 611, the clean hot water pump 612, and the clean cold water pump 613 are respectively arranged above the dirty hot water tank 63, the clean hot water tank 65, and the clean cold water tank 67.
[0068] As a further solution of this embodiment, the filter press device 64 is a filter press tank.
[0069] Specifically, preferably, a bag type filter press tank is adopted, and the mesh size of the filter press bag can be selected according to the usage situation.
[0070] The process of using the spray water comprehensive treatment tank 6 of the present invention is as follows: The oily hot water generated in the flue gas treatment tank 3 enters the treatment tank body from the oily hot water inlet 61. The oily hot water is separated into oil and water in the oil-water separation device 62. The separated tar enters the tar tank 68 along the pipeline, and the separated dirty hot water enters the dirty hot water tank 63. The dirty hot water in the dirty hot water tank 63 is pumped into the filter press device 64 by the dirty hot water pump 611. The filter press device 64 separates the dirty hot water into sludge and clean hot water. The sludge needs to be cleaned regularly or discharged to an external sludge collection device. The clean hot water enters the plate heat exchanger 66 to be cooled and become clean cold water. The clean cold water enters the clean cold water tank 67. The lye tank 610 adds lye to the clean cold water tank 67 regularly. The clean cold water is pumped from the spray water outlet into the spray pipe 341 of the flue gas treatment tank 3 by the clean cold water pump 613.
[0071] As a further solution of this embodiment, as Figure 2As shown in the figure, the feeding device 1 includes a tubular housing 11, a chain conveyor 12 and a pusher 13. One end of the housing 11 has a feeding port 1101, and the other end has a receiving port 1102. One end of the housing 11 near the receiving port 1102 has a convex section protruding upward, and the convex section is higher than the feeding port 1101 and the receiving port 1102. The chain conveyor 12 is fixedly arranged in the housing 11 and is used to convey materials from the feeding port 1101 to the receiving port 1102. The pusher 13 is rotatably connected to the side wall of the receiving port 1102 and is used to push the materials out of the receiving port 1102. The receiving port 1102 is communicated with the feeding port of the box-type pyrolysis gasification furnace 2.
[0072] As a further solution of this embodiment, the top of the convex section is communicated with the secondary combustion chamber 32 of the flue gas treatment box 3 through a connecting pipe, and a blower 322 is also arranged on the connecting pipe. The blower 322 pumps the gas in the feeding device 1 into the secondary combustion chamber 32.
[0073] As a further solution of this embodiment, the pusher 13 includes a pressing block 1301 and a pressing driving mechanism 1302. The lower side wall of the housing 11 near the receiving port 1102 has a pressing port. The pressing block 1301 is rotatably connected to the side wall of the housing 11 and is located in the pressing port. The pressing driving mechanism 1302 drives the pressing block 1301 to rotate; the pressing block 1301 has a pressing surface 13011 and a mating surface 13012. The pressing surface 13011 is used to push the materials out of the receiving port 1102, and the mating surface 13012 abuts against the side wall of the pressing port during the rotation of the pressing block 1301.
[0074] As a further solution of this embodiment, the feeding port 1101 is lower than the receiving port 1102, and the discharging end of the chain conveyor 12 is higher than the receiving port 1102.
[0075] Specifically, as Figure 2 shown, the housing 11 near the receiving port 1102 is in a shape with the middle high and both ends low, and the structure of the housing 11 looks similar to a bird's beak. Since hot air will rise in a natural state, this structure can keep the hot air at the top of the housing, which is beneficial to heat preservation and preliminary drying of the materials. One end of the chain conveyor 12 is arranged in the receiving port 1102, and the other end extends obliquely upward to the highest point of the bottom wall of the convex section.
[0076] As a further solution of this embodiment, the housing 11 is a tubular shape with a rectangular cross-section.
[0077] As a further solution of this embodiment, a heat preservation layer is arranged on the inner or outer side of the housing 11.
[0078] Specifically, as Figure 2 shown, the two sector-shaped end walls and the arc-shaped side wall on the pressure block 1301 are the mating surfaces 13012.
[0079] As a further solution of this embodiment, the pressure block 1301 is a column with a sector-shaped cross-section, the pressure opening is rectangular, the pressure block 1301 is rotatably connected to one side wall of the pressure opening close to the material receiving port 1102, and the mating surface 13012 abuts against the other three side walls of the pressure opening.
[0080] As a further solution of this embodiment, the pressure driving mechanism 1302 is a hydraulic cylinder, and the output end of the hydraulic cylinder is hinged to the bottom wall of the pressure block 1301. The cylinder body of the hydraulic cylinder is hinged to an external support, and the hydraulic station 14 is communicated with the oil cavity of the hydraulic cylinder to supply oil to it.
[0081] Specifically, the pressure driving mechanism 1302 can also be a pressure motor. The pressure motor is fixedly connected to the outer side wall of the housing 11, a gear is fixedly connected to the output shaft of the pressure motor, an arc-shaped rack is fixedly connected to the outer arc surface of the pressure block 1301, the gear meshes with the arc-shaped rack, and the pressure motor drives the gear to rotate, thereby driving the pressure block 1301 to rotate.
[0082] Specifically, the pressure surface 13011 can also be an arc surface. When the pressure surface 13011 is an arc surface, when the pressure surface rotates to face the reaction kettle 21, the arc surface of the pressure surface 13011 is recessed toward the side away from the reaction kettle 21, and the pressure surface 13011 generates a pressure toward the center of curvature, which can better break the material bridging phenomenon, especially suitable for pressing non-homogeneous organic solid waste.
[0083] The using process of the feeding device is as follows: The organic solid waste without prior homogenization treatment is added to the chain conveyor 12 in the feeding port 1101 by a shovel (bucket) truck or manually. As the conveyor belt of the chain conveyor 12 rotates, the garbage is conveyed obliquely upward. The pressure block 1301 rotates counterclockwise driven by the hydraulic cylinder until the pressure surface 13011 faces the material receiving port 1102, and the material enters the box-type pyrolysis gasification furnace 2 from the material receiving port 1102 for subsequent treatment. During the rotation of the pressure block 1301, the mating surface 13012 abuts against the side wall of the pressure opening to prevent the material from leaking. After the pressing is completed, the pressure block 1301 can close the material receiving port 1102 to prevent the hot gas of the subsequent treatment equipment from leaking out. When the next feeding is required, the pressure block 1301 rotates clockwise back to Figure 2The position shown. The feeding device 1 of the present invention is applicable to small machinery (forklift trucks) or manual feeding. The setting of the pusher can avoid the process interruption caused by tower bridges, etc. during the feeding of inhomogeneous organic solid waste. The housing that is enclosed on all sides only includes a feeding port and a receiving port, and the receiving port is connected to the subsequent treatment equipment, so that the housing can prevent the odor from overflowing. The tubular housing serves as the drying section. Since the receiving port is connected to the treatment equipment, the temperature in the treatment equipment will cause the temperature in the housing to rise. The tubular structure is beneficial for heat preservation and enables it to have a preliminary drying function, which is beneficial for the subsequent treatment.
[0084] As a further solution of this embodiment, as Figures 3-9 shown, the box-type pyrolysis gasification furnace 2 includes a reaction kettle 21 and a pyrolysis box body 23. The reaction kettle 21 rotates horizontally axially in the pyrolysis box body 23. The reaction kettle 21 includes a reaction kettle main body 211, a transition section 212, and a feeding cylinder 213. The reaction kettle main body 211 is in the shape of a cylinder with one end closed and the other end open. The other end of the reaction kettle main body 211 is fixedly connected or integrally formed and communicated with one end of the feeding cylinder 213 through the transition section 212. The diameter of the feeding cylinder 213 is smaller than the diameter of the reaction kettle main body 211. The other end of the feeding cylinder 213 passes through the pyrolysis box body 23 and is communicated with the receiving port 1102 of the feeding device 1. The side wall of the reaction kettle main body 211 has a discharge port 2111, the bottom wall of the pyrolysis box body 23 has a slag discharge port 233, and the top of the pyrolysis box body 23 has a flue gas outlet 232. The flue gas outlet 232 is communicated with the flue gas inlet 311 of the flue gas treatment box 3.
[0085] Specifically, when the discharge port 2111 rotates to the lowermost position of the reaction kettle 21, the slag discharge port 233 is located directly below the discharge port 2111.
[0086] Specifically, the reaction kettle 21 composed of the reaction kettle main body 211, the transition section 212, and the feeding cylinder 213 is in the shape of a bottle.
[0087] Specifically, the feeding device 1 is fixed. As Figure 2 shown, the receiving port 1102 has an outward flanging. As Figure 3 shown, the other end of the feeding cylinder 213 is sleeved inside or outside the receiving port 1102 through a bearing and is communicated with the feeding device 1.
[0088] As a further solution of this embodiment, one end of the reactor main body 211 has a pyrolysis gas outlet 2112, and the pyrolysis gas outlet 2112 is communicated with the outside of the pyrolysis box body 23 through a pipeline. The pyrolysis gas can be transported to a power plant for power generation through the pyrolysis gas outlet 2112, or stored as an energy source after being transported out. The main component of this part of the gas is methane. The beneficial effect of adopting the above further solution is that one end of the reactor main body 211 is far from the feeding device 1, and the pyrolysis gas in this part has a low moisture content, a high concentration of organic small molecules and a low tar content, which is convenient for direct collection and utilization.
[0089] Specifically, since there is a connecting pipeline on the top wall of the housing 11 of the feeding device 1 and there is a blower 322 on the connecting pipeline, when the receiving port 1102 is opened, the blower 322 draws part of the pyrolysis gas out of the feeding device 2, forming a countercurrent pyrolysis with high pyrolysis efficiency. The pyrolysis gas drawn out by the blower 322 has a high moisture content, a low concentration of organic small molecules and a high tar content, and cannot be directly utilized. Further pyrolysis gas treatment is required before utilization. The pyrolysis gas at both ends of the reactor is discharged respectively, and the pyrolysis gas far from the feeding device 2 is directly utilized, and the pyrolysis gas at the feeding device 2 is utilized after entering the flue gas treatment box 3 for treatment. This avoids treating all the pyrolysis gas together and avoids mixing and treating the directly utilizable pyrolysis gas with the non-directly utilizable pyrolysis gas, resulting in energy waste.
[0090] As a further solution of this embodiment, it further includes a chain grate hot blast stove 25. The pyrolysis box body 23 is divided into an upper cavity and a lower cavity by a partition plate. The reactor 21 is arranged in the upper cavity. The partition plate has a discharge port 231 corresponding to the lower part of the discharge port 2111. The feeding end of the chain grate hot blast stove 25 is fixed in the lower cavity and is located below the discharge port 231. The bottom wall of the pyrolysis box body 23 has a slag discharge port 233 corresponding to the discharge end of the chain grate hot blast stove 25. The beneficial effect of adopting the above further solution is that a box-type pyrolysis gasification furnace equipped with a bottle-shaped reactor can complete the processes of feeding, charging, pyrolysis, slag discharging, melting and slag discharging, realizing the effective treatment of heterogeneous organic solid waste.
[0091] Specifically, the chain grate hot blast stove 25, also known as a chain grate furnace, is a type of traveling grate furnace and belongs to a mechanically fired grate. Working principle: The chain grate is driven to rotate by a speed reducer, so that the carbon slag ignites from the feeding end and burns out at the discharge end, which can improve the combustion efficiency compared with a fixed grate. At the same time, when the chain turns to the lower part, it is cooled by air to protect the grate bars from burning out. It is a relatively good combustion device in traveling grate furnaces. The combustion gas enters the upper cavity and keeps the reactor 21 warm. The materials discharged from the slag discharge port 233 are collected and processed uniformly.
[0092] As a further solution of this embodiment, it further includes a discharge door 27. The discharge door 27 is arranged inside the reactor main body 211. One side of it is hinged to any side of the discharge port 2111 along the circumferential direction of the reactor main body 211. The discharge door 27 can be rotated to abut against the inner side wall of the reactor main body 211 and completely block the discharge port 2111, and can be rotated to open the discharge port 111 and communicate the inside and outside of the reactor main body 211. The beneficial effect of adopting the above further solution is that: one side of the discharge door 27 is hinged to one side of the discharge port 2111 along the circumferential direction of the reactor main body 211, with a simple structure and being convenient for production and manufacturing. In this way, in the discharging state, when the reactor main body 211 rotates towards the hinged end of the discharge door 27, the discharge door 27 is in the open state when it rotates to the bottom of the reactor main body 211; in the pyrolysis state, when the reactor main body 211 rotates towards the other end of the discharge door 27, the discharge door 27 is in the closed state when it rotates to the bottom of the reactor main body 211. By changing the rotation direction of the reactor main body 211, the state of the discharge door 27 when it moves to the bottom can be controlled, so that discharging can be carried out during the pyrolysis process without affecting the pyrolysis process.
[0093] Specifically, as Figure 5 and Figure 6 shown, one side of the discharge door 27 is hinged to the reactor 21. As the reactor 21 rotates, the discharge door 27 opens or closes. As Figure 6 shown, Figure 6 in 1-1 to 1-4 represent the states of the discharge door 27 at four positions during the counterclockwise rotation of the reactor 21. The counterclockwise rotation of the reactor 21 is the pyrolysis state of the reactor. The reactor 21 rotates along the direction from one side of the discharge door 27 to the other side. That is to say, the counterclockwise rotation means that the hinge point of the discharge door 27 is located behind the rotation direction. When the discharge door 27 rotates to the lower part, that is, at the position shown in 1-3, the discharge door 27 is closed. As Figure 6 shown, 2-1 to 2-4 in the figure represent the states of the discharge door 27 at four positions during the clockwise rotation of the reactor 21. The clockwise rotation of the reactor 21 is the feeding state of the reactor. The reactor 21 rotates along the direction from the other side of the discharge door 27 to one side. That is to say, the clockwise rotation means that the hinge point of the discharge door 27 is located in front of the rotation direction. When the discharge door 27 rotates to the lower part, that is, at the position shown in 2-3, the discharge door 27 is open.
[0094] As a further solution of this embodiment, the discharge door 27 is provided with a plurality of sieve holes. The beneficial effect of adopting the above further solution is that the box-type pyrolysis gasification furnace equipped with the bottle-shaped reaction kettle is suitable for the pyrolysis of heterogeneous organic solid waste. During the pyrolysis process, the completely pyrolyzed organic solid waste will form carbon slag, which can be directly discharged from the sieve holes during the pyrolysis process; the incompletely pyrolyzed organic solid waste remains in the reaction kettle; materials that cannot be pyrolyzed can be discharged during discharging.
[0095] Specifically, as Figure 5 and Figure 6 shown, during the material processing, the heterogeneous material includes inorganic materials that cannot be pyrolyzed and organic materials that can be pyrolyzed. Among them, the organic materials include materials that are easily pyrolyzed and materials that are not easily pyrolyzed. Materials that are not easily pyrolyzed are such as furniture and wood, etc., and materials that are easily pyrolyzed are such as plastic films and plastic lunch boxes, etc. Since the heterogeneous material is not classified and homogenized before being put into the reaction kettle 21, the materials that are easily pyrolyzed will be pyrolyzed into carbon slag first, and the materials that are not easily pyrolyzed need to be pyrolyzed into carbon slag after a long time of pyrolysis. Therefore, in the pyrolysis state, when the reaction kettle 21 rotates to Figure 6 in the 1-3 state among them, the carbon slag can be directly discharged through the sieve holes on the discharge door 27 during the pyrolysis process. If there is a large amount of inorganic material that cannot be pyrolyzed accumulated in the reaction kettle 21, the reaction kettle 21 rotates clockwise. In the discharging state, the reaction kettle 21 rotates to Figure 6 in the 2-3 state among them, and the materials that cannot be pyrolyzed are discharged from the discharge port 2111. The beneficial effect is that the reaction kettle 21 needs to work at a high temperature and is arranged in the pyrolysis box body 23. If a closed discharge door is set, when discharging, it is necessary to wait for the reaction kettle 21 to cool down before manually opening it. This not only greatly reduces the production efficiency but also wastes heat energy. After restarting the reaction kettle, it still needs to be reheated, and the heat energy loss is large. By adopting the discharge door 27 of the present invention, discharging can be carried out without stopping the machine, and the production efficiency is high. And through a large number of experiments, it is proved that in the 1-1, 1-2, 1-4, 2-1, 2-2, and 2-4 states, the materials will not fall out of the reaction kettle 21, solving the discharging problem of heterogeneous materials during pyrolysis in the reaction kettle.
[0096] As a further solution of this embodiment, a plurality of material lifting plates 28 are further fixed in the reaction kettle body 211, and a guide plate 29 for guiding the material into the reaction kettle body 211 is further fixed in the transition section 212 and the feed cylinder 213. The beneficial effect of adopting the above further solution is that the guide plate helps the material to quickly enter the reaction kettle body, and the feeding efficiency is high.
[0097] Specifically, as Figure 3 、 Figure 4 and Figure 7As shown, a plurality of material lifting plates 28 are evenly distributed in the circumferential direction of the reaction kettle 21 to form a material lifting plate group, and a plurality of material lifting plate groups are arranged side by side along the axial direction of the reaction kettle 21. In order not to affect the opening and closing of the discharge door 27, no material lifting plate 28 is provided within the rotation range of the discharge door 27. As Figure 7 shown, the material lifting plate 28 is plate-shaped, one end of the material lifting plate 28 is fixedly connected to the inner wall of the reaction kettle 21, one end of the material lifting plate 28 is arranged along the radial direction of the reaction kettle 21, and the other end has an included angle α with the radial direction of the reaction kettle 21, and the included angle α is 0-90°. The bending direction of the other end of the material lifting plate 28 faces the rotation direction of the reaction kettle 21.
[0098] Specifically, as Figure 8 and Figure 9 shown, the guide plate 29 is arranged along a spiral direction in the transition section 212 and the feed cylinder 213. As Figure 8 shown, the guide plate 29 can be a plurality of rectangular plates, and a plurality of guide plates 29 are arranged along a spiral direction. As Figure 9 shown, the guide plate 29 can also be a spiral strip plate, and the outer side of the guide plate 29 is fixedly connected to the transition section 212 and the feed cylinder 213.
[0099] Specifically, as Figure 3 shown, both ends of the reaction kettle 21 pass through two opposite side walls of the pyrolysis box body 23 and are rotatably connected to the pyrolysis box body 23. A transmission gear ring is sleeved on any one end of the reaction kettle 21. Further included is a reaction kettle motor 216. A transmission gear is coaxially fixed to the output shaft of the reaction kettle motor 216, and the transmission gear meshes with the transmission gear ring. The reaction kettle motor 216 rotates and drives the transmission gear ring to rotate through the transmission gear, thereby enabling the reaction kettle 21 to horizontally rotate around its axis. Fixed frames are respectively fixed below both ends of the pyrolysis box body 23, the reaction kettle motor 216 is fixed on the fixed frames, and a supporting wheel 215 is rotatably connected to each fixed frame. Specifically, a supporting wheel shaft parallel to the axis of the reaction kettle 21 is rotatably connected to the fixed frame, the supporting wheel 215 is coaxially fixedly connected to the supporting wheel shaft, the supporting wheel 215 is a gear, rolling rings 214 are respectively sleeved on both ends of the reaction kettle 21, the rolling rings 214 are gear rings, the supporting wheel 215 meshes with the rolling rings 214, and as the reaction kettle 21 rotates, the rolling rings 214 drive the supporting wheels 215 to rotate accordingly. The supporting wheels 215 and the rolling rings 214 play a role in supporting and positioning.
[0100] As a further solution of this embodiment, as Figure 10As shown in the figure, the flue gas treatment box 3 includes a flue gas box body 31, which is separated into a secondary combustion chamber 32, a heat exchange area 33, a desulfurization and denitrification area 34, and a dust and mist removal area 35 that are connected in sequence by a partition. The flue gas box body 31 has a flue gas inlet 311 and a flue gas outlet 312. The secondary combustion chamber 32 is communicated with the flue gas outlet 232 of the box-type pyrolysis gasification furnace 2 through the flue gas inlet 311, and the dust and mist removal area 35 is communicated with the inlet of the activated carbon adsorption box 4 through the flue gas outlet 312.
[0101] As a further solution of this embodiment, a combustion gun 321 for raising the temperature of the secondary combustion chamber 32 is provided on the side wall of the secondary combustion chamber 32. The beneficial effect of adopting the above further solution is that the combustion gun raises the temperature of the secondary combustion chamber, and the gaseous small molecule pollutants that are not completely oxidized are oxidized in the secondary combustion chamber.
[0102] Specifically, the combustion gun 321 is installed on the outer side wall of the flue gas box body 31, and the gun head of the combustion gun 321 extends into the secondary combustion chamber 32 to heat the flue gas in the secondary combustion chamber 32, so that the gaseous molecules that are not completely oxidized in the flue gas can be oxidized at high temperature.
[0103] As a further solution of this embodiment, the side wall of the secondary combustion chamber 32 also has a secondary air duct, and a blower 322 is fixed in the secondary air duct for introducing air into the secondary combustion chamber 32. The beneficial effect of adopting the above further solution is that blowing air into the secondary combustion chamber helps the gaseous pollutants to flow forward, and enables the oxygen in the air to enter the flue gas box body, which is beneficial to the oxidation of pollutants. At the same time, the harmful gases in the feeding device are drawn into the secondary combustion chamber 32 for treatment.
[0104] As a further solution of this embodiment, it further includes a heat exchanger 331 for cooling the flue gas, and the heat exchanger 331 is fixedly connected in the heat exchange area 33. The beneficial effect of adopting the above further solution is that the refrigerant in the heat exchanger absorbs the heat of the flue gas, realizing the cooling of the flue gas and the utilization of the waste heat of the flue gas.
[0105] Specifically, the heat exchanger 331 can be a tube-type heat exchanger or a plate-type heat exchanger in the prior art, or other existing heat exchangers in other forms. The heat exchanger 331 has a refrigerant inlet and a refrigerant outlet, and both the refrigerant inlet and the refrigerant outlet are communicated with the refrigerant pipeline outside the flue gas box body 31. The refrigerant is water or coolant or other common cooling media. When the refrigerant is water, the hot water discharged from the refrigerant outlet can be supplied to places where hot water is needed to realize the effective utilization of heat.
[0106] As a further solution of this embodiment, it further includes a spray pipe 341, which is fixedly arranged on the top wall of the desulfurization and denitrification area 34. The spray pipe 341 is connected to the spray water outlet of the spray water comprehensive treatment tank 6 and is used to introduce spray water into the desulfurization and denitrification area 34. The bottom wall of the flue gas box body 31 has a drain port, and the drain port is communicated with the oil-contaminated hot water inlet 61 of the spray water comprehensive treatment tank 6. The beneficial effect of adopting the above further solution is that wet desulfurization and denitrification are adopted. The wet desulfurization and denitrification technology is relatively mature, with a fast reaction speed, safe and reliable production operation, small occupied volume, suitable for small equipment, and can also achieve the cooling and dust removal of flue gas.
[0107] Specifically, the spray pipe 341 is communicated with the spray water outlet of the spray water comprehensive treatment tank 6. The spray water is an alkaline solution, which is the spray water used in wet desulfurization and denitrification in the prior art. The spray water is recycled and there is no pollutant discharge.
[0108] As a further solution of this embodiment, it further includes a wet electrostatic precipitator and demister 351, which is fixedly arranged in the dust removal and demister area 35. The beneficial effect of adopting the above further solution is that the wet electrostatic precipitator and demister removes particles and dust in the flue gas.
[0109] Specifically, the wet electrostatic precipitator and demister 351 can be a plate-type or tube-type wet electrostatic precipitator and demister in the prior art.
[0110] Specifically, the smoke exhaust port 12 is sequentially connected and communicated with the activated carbon adsorption box 4 and the smoking fan 5. The smoking fan 5 accelerates the flow of flue gas from the smoke inlet to the smoke exhaust port and discharges the treated flue gas out of the flue gas box body. The activated carbon in the activated carbon adsorption box 4 further filters and adsorbs the substances in the flue gas.
[0111] As a further solution of this embodiment, the secondary combustion chamber 32 is arranged at one end of the flue gas box body 31 and is divided into an inverted U shape by the first partition 313. The smoke inlet 311 is located at the bottom of one end of the flue gas box body 31, and the smoke inlet 311 is communicated with one side of the secondary combustion chamber 32 close to the end wall of the flue gas box body 31. The beneficial effect of adopting the above further solution is that the secondary combustion chamber is in an inverted U shape, with a long channel and a small floor area, ensuring that the flue gas stays in the secondary combustion chamber for enough time, enabling the flue gas to be fully oxidized or decomposed in the secondary combustion chamber, and at the same time realizing the miniaturization and integration of the garbage incineration flue gas comprehensive treatment tank.
[0112] Specifically, as Figure 10 shown, the secondary combustion chamber 32 is located at the right end of the flue gas box body 31 and is in an inverted U shape. The smoke inlet 11 is located at the bottom of the right end of the flue gas box body 31, and the smoke inlet 311 is communicated with the lower end on the right side of the secondary combustion chamber 32.
[0113] As a further solution of this embodiment, the heat exchange area 33, the desulfurization and denitrification area 34, and the dust removal and demisting area 35 are arranged at the other end of the flue gas box body 31 and are arranged in sequence from bottom to top. One end of the heat exchange area 33 is communicated with the secondary combustion chamber 32, the other end of the heat exchange area 33 is communicated with the other end of the desulfurization and denitrification area 34, one end of the desulfurization and denitrification area 34 is communicated with one end of the dust removal and demisting area 35, and the smoke exhaust port 312 is located on the top wall of the other end of the flue gas box body 31 and is communicated with the other end of the dust removal and demisting area 35. The beneficial effect of adopting the above further solution is that the flue gas (or pyrolysis gas) from waste incineration (or pyrolysis) enters the ∩-type secondary combustion chamber, and the secondary combustion chamber is heated to a high temperature (850°C - 1000°C) by a burner. The high-temperature flue gas enters from one end of the horizontally arranged heat exchange area communicated with the secondary combustion chamber, exchanges heat with a refrigerant (water, heat-conducting oil, etc.), the temperature of the flue gas is reduced to 150°C - 180°C, and it is discharged from the other end of the heat exchange area, rises and enters the desulfurization and denitrification area, where desulfurization and denitrification are carried out under the action of sprayed water (alkali solution), and the temperature is further reduced and dust is removed. Then it bends and rises into the dust removal and demisting area, and the tail gas after dust removal and white removal is discharged up to the standard through a smoke exhaust fan.
[0114] Specifically, as Figure 10 shown, the flue gas box body 31 is divided into the secondary combustion chamber 32, the heat exchange area 33, the desulfurization and denitrification area 34, and the dust removal and demisting area 35 by a first partition plate 313, a second partition plate 314, and a third partition plate 315. The first partition plate 313 is a vertical flat plate, the bottom end of the first partition plate 313 is fixedly connected to the bottom wall of one end of the flue gas box body 31, and the smoke inlet 311 is arranged between the first partition plate 313 and the end wall of one end of the flue gas box body 31. The second partition plate 314 is an L-shaped plate, one end of which is fixedly connected to the top wall of the flue gas box body 31, and the other end is horizontally arranged in a direction away from the first partition plate 313. The third partition plate 315 is a horizontally arranged plate, one end of which is fixedly connected to the end wall of the other end of the flue gas box body 31, and the third partition plate 315 is located above the other end of the second partition plate 314. A labyrinth channel is formed in the flue gas box body 31, and the flue gas can directly pass through the secondary combustion chamber 32, the heat exchange area 33, the desulfurization and denitrification area 34, and the dust removal and demisting area 35 in sequence without passing through a pipeline to complete the treatment of the flue gas. The system has a small wind resistance and a compact structure.
[0115] Specifically, the water discharged from the wet electrostatic precipitator and demister 351 can flow along the third partition plate 315 and the second partition plate 314 to the drain port at the bottom wall of the flue gas box body 31, and the functions of temperature reduction and dust removal can also be realized during the flowing process, thus realizing the sharing of refrigerant and cleaning medium and improving the efficiency. The liquid discharged from the drain port can be recycled and then introduced into the spray pipe 341 for recycling.
[0116] The flue gas (or pyrolysis gas) from waste incineration (or pyrolysis) enters the ∩-type secondary combustion chamber. The secondary combustion chamber is heated to a high temperature (850°C - 1000°C) by a burner. The high-temperature flue gas enters from one end of the heat exchange area that is horizontally placed and connected to the secondary combustion chamber, exchanges heat with the refrigerant (water, heat-conducting oil, etc.), the temperature of the flue gas drops to 150°C - 180°C, and it is discharged from the other end of the heat exchange area, then rises and enters the desulfurization and denitrification area, where desulfurization and denitrification are carried out under the action of sprayed water (alkali solution), and it is further cooled and dedusted. Then it bends and rises into the dust removal and demisting area. After dust removal and white smoke removal, the tail gas passes through the activated carbon adsorption box 4 and the smoking fan 5 and is discharged up to standard.
[0117] As a further solution of this embodiment, it further includes an electric control box 7. The controller in the electric control box 7 is electrically connected to devices such as the chain conveyor 12, the hydraulic station 14, the reaction kettle motor 216, the chain grate hot blast stove 25, the blower 322, the smoking fan 5, the dirty hot water pump 611, the clean hot water pump 612, the clean cold water pump 613, etc., and controls their start or stop, and controls the forward or reverse rotation of the reaction kettle motor 216. The above control process can be realized by existing technologies. For the sake of concise expression, it will not be elaborated here.
[0118] As Figure 1 shown, preferably, the box-type pyrolysis gasification furnace 2 and the sprayed water comprehensive treatment box 6 are arranged side by side below the flue gas treatment box 3. The feeding device 1 is located on one side of the box-type pyrolysis gasification furnace 2. The electric control box 7 is located above the box-type pyrolysis gasification furnace 2 and on one side of the flue gas treatment box 3. The activated carbon adsorption box 4 and the smoking fan 5 are located above the flue gas treatment box 3. It should be noted that the feeding device 1, the box-type pyrolysis gasification furnace 2, the flue gas treatment box 3, the activated carbon adsorption box 4, the smoking fan 5, the sprayed water comprehensive treatment box 6, and the electric control box 7 of the present invention can also adopt other arrangement methods, and their positional relationships can be flexibly adjusted. After adjustment, each box body can be connected by pipelines, and a fan can also be set on the connected pipelines to make the gas flow smoothly. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
[0119] The working process of the all-in-one small garbage processor of the present invention is as follows: The organic solid waste without prior homogenization treatment is added into the chain conveyor 12 in the feeding port 1101 by a shovel (bucket) truck or manually. As the conveyor belt of the chain conveyor 12 rotates, the garbage is conveyed obliquely upwards. The pressing block 1301 rotates counterclockwise driven by the hydraulic cylinder until the pressing surface 13011 faces the receiving port 1102, and the material enters the box-type pyrolysis gasification furnace 2 from the receiving port 1102. The inhomogeneous organic solid waste is pyrolyzed in the reaction kettle 21. The carbon slag or the material that cannot be pyrolyzed is further processed by the chain grate hot blast stove 25 and discharged from the slag discharge port 233. Part of the pyrolysis gas is exported from the pyrolysis gas outlet 2112 for power generation or used as energy, and the other part of the pyrolysis gas overflows from the discharge port 2111 and directly enters the flue gas treatment box 3 through the flue gas outlet 232. The flue gas (or pyrolysis gas) enters the ∩-type secondary combustion chamber 32. The secondary combustion chamber 32 is heated to a high temperature (850°C - 1000°C) by the combustion gun 321. The high-temperature flue gas enters from one end of the heat exchange area 33 which is horizontally placed and communicated with the secondary combustion chamber 32, exchanges heat with the refrigerant (water, heat-conducting oil, etc.), the temperature of the flue gas is reduced to 150°C - 180°C, and is discharged from the other end of the heat exchange area 33, rises and enters the desulfurization and denitrification area 34, where desulfurization and denitrification are carried out under the action of the sprayed water (alkali solution), further cooling and dust removal are carried out, then it bends and rises into the dust removal and demisting area 35, and the tail gas after dust removal and dewhiteing is discharged up to the standard through the activated carbon adsorption box 4 and the smoking fan 5.
