Description

Technical Field

[0001] This application relates to the field of waste incineration technology, and in particular to a heat compensation device for a leachate treatment system. Background Technology

[0002] With the rapid development of exhaust gas treatment technology, waste incineration has become one of the most important waste treatment methods today, effectively achieving waste reduction, harmlessness, and resource recovery. Before incineration, waste needs to be placed in a waste pit for fermentation, allowing moisture to be released and forming leachate, reducing the water content of the waste and thus improving incineration efficiency. However, the process of leachate release during waste fermentation is greatly affected by ambient temperature, especially in cold winters. Therefore, a heat compensation device for the leachate treatment system needs to be designed.

[0003] A related leachate treatment system heat compensation device includes a waste pit, a heating flue, and an incinerator. The waste pit is used to store fermented waste, the incinerator incinerates the waste, and the heating flue transmits the high-temperature flue gas generated by the incinerator through the periphery of the waste pit, thereby heating the waste pit.

[0004] However, the heat compensation device in an existing leachate treatment system is prone to clogging the heating flue due to the large amount of dust particles in the high-temperature flue gas, and the direct heat transfer through the high-temperature flue gas makes it difficult to control the temperature of the waste pit. Utility Model Content

[0005] To reduce the problems of temperature control difficulties and easy blockage of heating flue gas during high-temperature flue gas heating, this application provides a heat compensation device for a leachate treatment system.

[0006] This application provides a heat compensation device for a leachate treatment system, which adopts the following technical solution: A heat compensation device for a leachate treatment system, comprising: The garbage pit is fixedly set on the ground. A fermentation chamber is set inside the garbage pit. A feed inlet is set around the garbage pit and is connected to the fermentation chamber. An incinerator is fixedly installed on the ground. The incinerator contains a combustion chamber and a heating chamber, which are higher than the combustion chamber. The feeding channel is fixedly connected to the garbage pit at one end and to the incinerator at the other end. The fermentation chamber and the incineration chamber are connected through the feeding channel, and a gate is installed on the feeding channel. The percolation assembly is vertically installed inside the fermentation chamber; The heat transfer component is fixedly connected at one end to the incinerator and at the other end to the waste pit. The heat transfer component can transfer the heat generated by the incinerator to the waste pit.

[0007] By adopting the above technical solution, the waste pit provides a fermentation space for the waste. Workers can put the waste into the fermentation chamber through the inlet. The leachate component can separate the waste in the waste pit from the leachate produced during fermentation, and the fermented waste is transported to the incinerator for incineration through the feeding channel. The heat transfer component can transfer the heat generated by the incinerator to the waste pit, allowing workers to control the fermentation temperature in the waste pit and improving the efficiency of waste fermentation. The setting of the heat transfer component can reduce the direct contact between high-temperature flue gas and the waste pit, making the heat transfer more uniform and easier to control, while reducing the probability of dust particles in the high-temperature flue gas clogging the heating channel.

[0008] Optionally, the percolation assembly includes: The first telescopic rod is vertically fixed to the inner side wall of the fermentation chamber, and two sets of the first telescopic rod are symmetrically arranged along the central axis of the length of the waste pool. The second telescopic rod is vertically fixed to the inner side wall of the fermentation chamber, and two sets of the second telescopic rod are symmetrically arranged along the central axis of the length of the waste pool. The filter plate is horizontally set inside the fermentation chamber. The end of the filter plate away from the feed inlet is rotatably connected to two sets of second telescopic rods. The filter plate is vertically provided with filter holes, and multiple sets of filter holes are spaced along the upper surface of the filter plate. A connecting frame is horizontally fixed on the filter plate. A sliding groove is horizontally provided on the connecting frame. Two sets of connecting frames are provided corresponding to the first telescopic rod. The slider has one end rotatably mounted on the telescopic end of the first telescopic rod, and the other end of the slider is embedded in the slide groove. The slider is slidably connected to the connecting frame.

[0009] By adopting the above technical solution, the shortening of the first telescopic rod can drive the slider and the connecting frame to move synchronously. The movement of the connecting frame can drive the filter plate to move closer to the first telescopic rod. The shortening of the second telescopic rod can drive the filter plate to move closer to the second telescopic rod. When the shortening distance of the first telescopic rod and the second telescopic rod are the same, the filter plate moves away from the bottom of the fermentation chamber, thereby separating the waste and leachate on the filter plate. When the shortening distance of the first telescopic rod is greater than the shortening distance of the second telescopic rod, the filter plate will change from a horizontal state to an inclined state, and the waste will slide off the filter plate into the feeding channel and finally enter the incineration chamber, thereby realizing the incineration of waste.

[0010] Optional, the heat transfer components include: The first induced draft fan is fixedly installed around the garbage pit. The input end of the first induced draft fan is connected to the fermentation chamber, and the output end of the first induced draft fan is connected to the heating chamber through an air pipe. The second induced draft fan is fixedly installed around the incinerator. The input end of the second induced draft fan is connected to the heating chamber, and the output end of the second induced draft fan is connected to the fermentation chamber through a gas pipe.

[0011] By adopting the above technical solution, the first induced draft fan can transport the cold air in the fermentation chamber to the heating chamber for heating through the pipeline, and the second induced draft fan can transport the heated air back to the fermentation chamber through the pipeline, thereby increasing the temperature in the garbage pit, reducing the situation where high-temperature flue gas directly heats the garbage pit, making the heating temperature of the garbage pit easier to control, and reducing the probability of dust particles in the high-temperature flue gas clogging the heating channel.

[0012] Optionally, a cover is rotatably installed at the end of the waste pit near the inlet.

[0013] By adopting the above technical solution, the cover plate creates a sealed space in the garbage pit, reducing heat loss and odor emission.

[0014] Optionally, a temperature sensor may be fixedly installed inside the waste collection pit.

[0015] By adopting the above technical solution, the temperature sensor enables staff to monitor the temperature changes inside the waste pit in real time, allowing them to adjust the temperature in the waste pit promptly through the heat transfer components, thus maintaining a suitable fermentation temperature inside the waste pit.

[0016] Optionally, the heating chamber is arranged in a spiral shape.

[0017] By adopting the above technical solution, the spiral arrangement of the heating chamber can increase the residence time of the cold air input into the heating chamber through the first induced draft fan, so that the cold air in the heating chamber can fully absorb the heat generated by the incinerator.

[0018] Optionally, an aerator is installed at the bottom of the fermentation chamber, and the aerator is connected to the output end of the second blower through an air pipe.

[0019] By adopting the above technical solution, the aerator can increase the contact area between hot air and leachate, improve the heating effect of hot air on leachate in fermentation chamber, and increase the activity of bacteria in leachate, thereby accelerating the fermentation of waste.

[0020] Optionally, a three-way valve is installed on the gas pipe connecting the first induced draft fan and the heating chamber. The normally open end of the three-way valve is connected to the heating chamber through the gas pipe, and the normally closed end of the three-way valve is connected to the combustion chamber through the gas pipe.

[0021] By adopting the above technical solution, the three-way valve allows the staff to control the first induced draft fan to transport the gas generated in the fermentation chamber to the incineration chamber through the branch of the three-way valve. The fermentation gas can improve the incineration efficiency of the waste in the incineration chamber, while reducing the probability of fermentation gas escaping.

[0022] In summary, this utility model provides a heat compensation device for a leachate treatment system, which has at least one of the following beneficial technical effects: 1. The waste pit provides a fermentation space for the waste. Workers can put the waste into the fermentation chamber through the inlet. The leachate component can separate the waste in the waste pit from the leachate produced during fermentation, and then transport the fermented waste to the incinerator for incineration through the feeding channel. The heat transfer component can transfer the heat generated by the incinerator to the waste pit, allowing workers to control the fermentation temperature in the waste pit and improving the efficiency of waste fermentation. The setting of the heat transfer component can reduce the direct contact between high-temperature flue gas and the waste pit, making the heat transfer more uniform and easier to control, while reducing the probability of dust particles in the high-temperature flue gas clogging the heating channel.

[0023] 2. The three-way valve allows staff to control the first induced draft fan to transport the gas produced by fermentation in the fermentation chamber to the incineration chamber through the branch of the three-way valve. The fermentation gas can improve the incineration efficiency of the waste in the incineration chamber and at the same time reduce the probability of fermentation gas escaping.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses a heat compensation device for a leachate treatment system, comprising: a waste pit 31, an incinerator 32, a feeding channel 33, a leachate assembly 1, and a heat transfer assembly 2; the waste pit 31 is fixedly installed on the ground, and a fermentation chamber 42 is provided inside the waste pit 31; a feed inlet 41 is provided around the waste pit 31 and communicates with the fermentation chamber 42; the incinerator 32 is fixedly installed on the ground, and a combustion chamber 43 is provided inside the incinerator 32; a heating chamber 44 is provided inside the incinerator 32, and the height of the heating chamber 44 is [not specified]. In the incineration chamber 43, one end of the feeding channel 33 is fixedly connected to the waste pool 31, and the other end of the feeding channel 33 is fixedly connected to the incinerator 32. The fermentation chamber 42 and the incineration chamber 43 are connected through the feeding channel 33. A gate 36 is provided on the feeding channel 33. The percolation component 1 is vertically installed in the fermentation chamber 42. One end of the heat transfer component 2 is fixedly connected to the incinerator 32, and the other end of the heat transfer component 2 is fixedly connected to the waste pool 31. The heat transfer component 2 can transfer the heat generated by the incinerator 32 to the waste pool 31.

[0028] In this embodiment, the waste pit 31 is rectangular, the fermentation chamber 42 is rectangular, and the feed inlet 41 is rectangular. A cover plate 34 is rotatably mounted on one end of the waste pit 31 near the feed inlet 41. The cover plate 34 is rectangular and rotatably mounted on one side of the length of the waste pit 31. The cover plate 34 can effectively prevent the diffusion of odors and heat loss in the waste pit 31, thus improving the heat preservation performance of the waste pit 31. The percolation assembly 1 is disposed in the fermentation chamber 42, and the operator can control the percolation assembly 1 to make the fermentation process... The fermented waste and leachate in the fermentation chamber 42 come into contact with or separate, and the fermented waste is then transported to the incineration chamber 43 through the feeding channel 33. The feeding channel 33 is funnel-shaped, with the larger cross-sectional area end connected to the fermentation chamber 42 and the smaller cross-sectional area end connected to the incineration chamber 43. Operators can control the opening and closing of the feeding channel 33 via valves, reducing the probability of high-temperature flue gas from the incineration chamber 43 entering the fermentation chamber 42 through the feeding channel 33. The working principle of the gate 36 is [not specified in the original text]. The technology is known, therefore it will not be described in detail in the embodiments of this application; the incinerator 32 is rectangular, the incineration chamber 43 is rectangular, the incineration chamber 43 is connected to the gas treatment device through the flue duct 47, the heating chamber 44 is spirally arranged, the heating chamber 44 is vertically arranged around the outside of the flue duct 47, and the heating chamber 44 is not connected to the flue duct 47, that is, the high-temperature flue gas in the flue duct 47 cannot enter the heating chamber 44, the medium in the heating chamber 44 can absorb the heat of the high-temperature flue gas in the flue duct 47, and the heat transfer component 2 heats the gas in the heating chamber 44. The medium is transported to the garbage pit 31, thereby heating the garbage pit 31. A temperature sensor 35 is fixedly installed inside the garbage pit 31. The staff can monitor the temperature of the garbage pit 31 in real time through the temperature sensor 35, so that the garbage pit 31 can be at a suitable temperature for fermentation even in cold winter. This improves the fermentation efficiency of the garbage pit 31 in winter and also reduces the problem of difficulty in controlling the temperature and easy blockage of the heating flue when directly using high-temperature flue gas for heating. This improves the convenience and accuracy of the staff in controlling the temperature of the garbage pit 31.

[0029] In practical use, the staff put the garbage into the garbage pit 31 through the feed inlet 41 and close the cover 34. After the garbage is fermented in the fermentation tank, the staff controls the leachate component 1 to separate the fermented garbage from the leachate. The staff opens the valve and transports the fermented garbage to the incineration chamber 43 through the feeding channel 33. The incinerator 32 incinerates the garbage. The high-temperature flue gas generated during the incineration process leaves the incinerator 32 through the exhaust duct 47. The heat transfer component 2 injects the cold air in the fermentation tank into the heating chamber 44. After the cold air absorbs the heat of the high-temperature flue gas, it is transported to the garbage pit 31 through the heat transfer component 2 to heat the garbage pit 31.

[0030] Combination Figure 1 , Figure 2and Figure 3 In one specific embodiment, the percolation assembly 1 includes: a first telescopic rod 11, a second telescopic rod 12, a filter plate 15, a connecting frame 14, and a slider 13; the first telescopic rod 11 is vertically fixed to the inner wall of the fermentation chamber 42, and two sets of the first telescopic rod 11 are symmetrically arranged along the central axis of the length direction of the waste pit 31; the second telescopic rod 12 is vertically fixed to the inner wall of the fermentation chamber 42, and two sets of the second telescopic rod 12 are symmetrically arranged along the central axis of the length direction of the waste pit 31; the filter plate 15 is horizontally arranged inside the fermentation chamber 42. One end away from the feed inlet 41 is rotatably connected to two sets of second telescopic rods 12. Filter holes 45 are vertically arranged on the filter plate 15. Multiple sets of filter holes 45 are arranged at intervals along the upper surface of the filter plate 15. The connecting frame 14 is horizontally fixed on the filter plate 15. A sliding groove 46 is horizontally arranged on the connecting frame 14. Two sets of connecting frames 14 are arranged corresponding to the first telescopic rods 11. One end of the slider 13 is rotatably arranged on the telescopic end of the first telescopic rod 11. The other end of the slider 13 is embedded in the sliding groove 46. The slider 13 is slidably connected to the connecting frame 14.

[0031] In this embodiment, the telescopic ends of the first telescopic rod 11 and the second telescopic rod 12 are both vertically downward. The filter plate 15 provides a space for the fermented waste. When the staff needs to separate the fermented waste from the leachate, the staff controls the first telescopic rod 11 and the second telescopic rod 12 to retract synchronously. The shortening of the first telescopic rod 11 drives the filter plate 15 to move synchronously through the slider 13 and the connecting frame 14. The shortening of the second telescopic rod 12 drives the filter plate 15 to move synchronously, thereby causing the filter plate 15 to move away from the bottom of the fermentation chamber 42. The filter holes 45 are cylindrical. Under the action of gravity, the leachate flows through the filter holes 45 to the bottom of the fermentation chamber 42, thereby achieving the purpose of separating the waste from the leachate. A drain pipe 40 is fixedly installed around the waste pit 31. The drain pipe 40 is cylindrical. The staff can use the drain pipe 40 to discharge the leachate from the waste pit 31 for subsequent treatment. When the operator controls the shortening of the first telescopic rod 11 to be greater than the shortening of the second telescopic rod 12, the filter plate 15 forms an angle with the rotating connection of the slider 13 and the second telescopic rod 12. The slider 13 slides along the direction of the slide groove 46, causing the end of the filter plate 15 near the feed inlet 41 to tilt upward and the end of the filter plate 15 near the feed channel 33 to tilt downward. This allows the fermented waste to slide down to one side of the feed channel 33 under the action of gravity and enter the incineration chamber 43 for incineration. The operator can control the contact state between the waste and the leachate through the first telescopic rod 11 and the second telescopic rod 12. When the waste needs to be fermented, the operator can control the filter plate 15 to immerse the waste in the leachate. The bacteria in the leachate will accelerate the fermentation process of the waste. After fermentation is completed, the operator controls the waste to separate from the leachate and enter the incineration chamber 43 for incineration, reducing the impact of the leachate on the incineration temperature.

[0032] In practical use, when the staff puts the garbage into the fermentation chamber 42, the staff controls the first telescopic rod 11 and the second telescopic rod 12 to extend towards the bottom of the fermentation chamber 42. The extension of the first telescopic rod 11 and the second telescopic rod 12 drives the filter plate 15 to move synchronously. The garbage on the filter plate 15 comes into contact with the leachate and ferments. When fermentation is complete, the staff controls the first telescopic rod 11 and the second telescopic rod 12 to retract. The amount of retraction of the first telescopic rod 11 is greater than the amount of retraction of the second telescopic rod 12. The two ends of the filter plate 15 move at different heights. The filter plate 15 changes from a horizontal state to an inclined state. The end of the filter plate 15 near the feed inlet 41 is higher than the end of the filter plate 15 away from the feed inlet 41. The fermented garbage slides down into the feeding channel 33 under the action of gravity. The staff opens the valve, and the garbage in the feeding channel 33 enters the incineration chamber 43 for incineration.

[0033] Combination Figure 1 , Figure 2 and Figure 4 In one specific embodiment, the heat transfer component 2 includes: a first induced draft fan 21 and a second induced draft fan 22; the first induced draft fan 21 is fixedly disposed around the garbage pit 31, the input end of the first induced draft fan 21 is connected to the fermentation chamber 42, and the output end of the first induced draft fan 21 is connected to the heating chamber 44 through the air pipe 37; the second induced draft fan 22 is fixedly disposed around the incinerator 32, the input end of the second induced draft fan 22 is connected to the heating chamber 44, and the output end of the second induced draft fan 22 is connected to the fermentation chamber 42 through the air pipe 37.

[0034] In this embodiment, the first induced draft fan 21, when activated, can input cold air from the fermentation tank into the heating chamber 44 through the air pipe 37. After entering the heating chamber 44, the cold air can absorb the heat of the high-temperature flue gas in the exhaust duct 47. The cold air spirals upward along the heating chamber 44 and gradually heats up into hot air. The second induced draft fan 22, when activated, can guide the hot air in the heating chamber 44 into the bottom of the fermentation chamber 42. The induced draft principle of the first induced draft fan 21 and the second induced draft fan 22 is prior art in this application embodiment, therefore, the induced draft principle of the first induced draft fan 21 and the second induced draft fan 22 is not specifically described in this embodiment. An aerator 38 is provided at the bottom of the fermentation chamber 42. The aerator 38 is connected to the output end of the second induced draft fan 22 through the air pipe 37. The aerator 38 is rectangular and has multiple sets of aeration holes. The aerator 38 can input the second induced draft fan 22 through the air pipe. The gas input at 37 is dispersed into multiple groups of small bubbles, increasing the contact area between the hot gas and the leachate, and enhancing the activity of bacteria in the leachate, thereby accelerating the efficiency of waste fermentation. A three-way valve 39 is installed on the gas pipe 37 connecting the first induced draft fan 21 and the heating chamber 44. The normally open end of the three-way valve 39 is connected to the heating chamber 44 through the gas pipe 37, and the normally closed end of the three-way valve 39 is connected to the incineration chamber 43 through the gas pipe 37. That is, the gas in the gas pipe 37 cannot enter the incineration chamber 43 through the three-way valve 39. When enough combustible gas is produced in the fermentation chamber 42, the operator activates the normally closed end of the three-way valve 39, so that the combustible gas produced in the fermentation chamber 42 is transported to the incineration chamber 43 through the gas pipe 37 under the action of the first induced draft fan 21, improving the incineration efficiency of the waste in the incineration chamber 43, while reducing the probability of fermentation gas escape, and improving the environmental performance and energy utilization rate of the heat compensation device.

[0035] In practical use, the staff starts the first induced draft fan 21. Under the action of the first induced draft fan 21, the cold air in the fermentation chamber 42 is transported to the heating chamber 44 through the air pipe 37. The cold air absorbs the heat from the flue 47 in the heating chamber 44 and becomes hot air. The staff then starts the second induced draft fan 22. Under the action of the second induced draft fan 22, the hot air in the heating chamber 44 is transported to the bottom of the fermentation chamber 42 through the air pipe 37. The hot air is dispersed into bubbles by the aerator 38 and enters the leachate, increasing the temperature of the waste pit 31 and the activity of bacteria in the leachate, thus accelerating the fermentation of the waste. The staff periodically starts the normally closed end of the three-way valve 39. The combustible gas in the fermentation chamber 42 is transported to the incineration chamber 43 through the air pipe 37 under the action of the first induced draft fan 21 and is burned.

[0036] It should be noted that the first telescopic rod 11, the second telescopic rod 12, the first induced draft fan 21, the second induced draft fan 22, and the temperature sensor 35 are electrically connected to an external power source. The heat compensation device of the leachate treatment system is equipped with a PLC control panel. The PLC control panel is electrically connected to the first telescopic rod 11, the second telescopic rod 12, the first induced draft fan 21, the second induced draft fan 22, and the temperature sensor 35. The extension and retraction of the first telescopic rod 11 and the second telescopic rod 12 can be controlled through the PLC control panel. The start of the first induced draft fan 21 and the second induced draft fan 22 can be controlled through the PLC control panel. The temperature detected by the temperature sensor 35 can be displayed through the PLC control panel.

[0037] The implementation principle of this application is as follows: Workers pour garbage into the garbage pit 31 through the inlet 41 and close the cover 34. Workers control the first telescopic rod 11 and the second telescopic rod 12 to extend towards the bottom of the fermentation chamber 42, causing the filter plate 15 to move synchronously. The garbage on the filter plate 15 comes into contact with the leachate and ferments. When fermentation is complete, workers control the first telescopic rod 11 and the second telescopic rod 12 to retract, causing the filter plate 15 to move synchronously. The garbage on the filter plate 15 separates from the leachate. The residual leachate on the filter plate 15 flows through the filter holes 45 to the bottom of the fermentation chamber 42. Because the retraction amount of the first telescopic rod 11 is greater than that of the second telescopic rod 12, the two ends of the filter plate 15 are at different heights and tilt. The garbage on the filter plate 15 slides down into the feeding channel 33. Personnel open the valve, and the garbage in the feeding channel 33 enters the incineration chamber 43 for incineration. The staff then activates the first induced draft fan 21, and the cold air in the fermentation chamber 42 is transported to the heating chamber 44 through the air pipe 37 under the action of the first induced draft fan 21. The cold air absorbs the heat generated by the garbage incineration and heats up into hot air. The staff then activates the second induced draft fan 22, and the hot air in the heating chamber 44 is transported to the aerator 38 through the air pipe 37 under the action of the second induced draft fan 22. The hot air is dispersed into bubbles by the aerator 38 and enters the leachate, increasing the temperature of the garbage pit 31 and the activity of bacteria in the leachate, thus accelerating the fermentation of the garbage. The staff periodically activates the normally closed end of the three-way valve 39, and the combustible gas in the fermentation chamber 42 is transported to the incineration chamber 43 through the air pipe 37 under the action of the first induced draft fan 21 for combustion.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
