Description

Technical Field

[0001] The invention relates to the technical field of garbage disposal, in particular to a leachate circulation heating system. Background Art

[0002] Leachate is the liquid formed when landfill waste mixes with rainwater or groundwater. It contains various hazardous chemicals and requires specialized treatment before it can be discharged or reused. Heating leachate can help speed up the treatment process, improve treatment efficiency, or meet the requirements of specific treatment technologies.

[0003] For example, the Chinese patent document with the authorization announcement number CN111396884B discloses a leachate circulation heating system, including a stacking chamber, a preheating chamber, a fermentation chamber and a discharge chamber, a liquid collecting tank is arranged at the bottom of the preheating chamber, and a liquid storage tank is arranged at the bottom of the fermentation chamber; connecting grooves are provided on the bottom surfaces of the preheating chamber and the fermentation chamber, the connecting groove on the bottom surface of the preheating chamber is the first groove, and the connecting groove on the bottom surface of the fermentation chamber is the second groove, a heating device is fixedly arranged in the liquid storage tank, and an anti-escape device is fixedly installed on the top of the liquid storage tank, the anti-escape device allows the water leachated in the fermentation chamber to seep into the liquid storage tank, while the gas in the liquid storage tank cannot directly escape into the fermentation chamber, and an upper connecting pipe is connected between the upper end of the liquid storage tank and the upper end of the liquid collecting tank. The treatment method of this patent can reduce the moisture in the garbage to be incinerated and improve the garbage combustion efficiency.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] At present, the heating components in the leachate heating system, such as the heat exchange tubes, are mostly fixedly arranged inside the liquid storage tank. However, since the leachate is an organic wastewater with a relatively high concentration, and no cleaning structure is provided for the heat exchange tubes, thicker dirt often adheres to the outer wall of the heat exchange tubes after a long period of use, which often affects the heat exchange effect to a large extent, and affects the heating of the leachate, which is not conducive to the heating and fermentation of the garbage above. At the same time, the fixed arrangement of the heat exchange tubes in the prior art also makes the heat exchange position relatively fixed, and the leachate is also in a relatively static state, resulting in the uniformity of the heating of the leachate being relatively general, so there are limitations.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention provides a leachate circulation heating system through improvement. The technical solution of the present invention is:

The auxiliary heat exchange mechanisms include a plurality of heat exchange cavity tubes 404 slidably installed on the mounting plates 3 in the vertical direction. The bottom ends of the plurality of heat exchange cavity tubes 404 are fixedly installed with bottom ring plates 406, and connecting springs 407 are fixed between the bottom ring plates 406 and the bottom sides of the mounting plates 3. Through the above structure, when the leachate is heated by heat exchange with the heat exchange branch pipe 604, hot steam can be generated. When the leachate enters the heat exchange cavity tube 404, the garbage inside the fermentation box 2 can be heated to ensure that the fermentation temperature is met. The heat exchange cavity tube 404 can penetrate into the garbage inside the fermentation box 2 to increase the heat exchange area, realize three-dimensional heating, and ensure the overall heating effect of the garbage in the fermentation box 2.

[0040] As a further solution of the present invention, a middle plate 201 is fixedly connected to the middle end of the bottom of the fermentation box 2, connecting plates 303 are fixed to both sides of the bottom of the fermentation box 2, and cavity plates 301 are connected to both sides of multiple mounting plates 3 through hinges.

[0041] Furthermore, a filter plate 302 is slidably installed inside each cavity plate 301, and the bottom of the filter plate 302 is connected to the adjacent connecting plate 303 and the middle end plate 201 through a hinge.

[0042] Through the above structure, using the setting Figure 6 , Figure 8 as well as Fig. 9The cavity plate 301 and the filter plate 302 shown are arranged at an angle, which is more conducive to the flow of the leachate on the one hand, and on the other hand, the hot steam generated in the liquid receiving box 1 can also contact the garbage inside the fermentation box 2 in a more three-dimensional manner, which is conducive to improving the heating efficiency and ensuring the fermentation effect.

[0043] Furthermore, an extension column 403 is fixedly connected to the top of each heat exchange cavity tube 404, side frames 4 are fixedly installed on the outer walls of both sides of the fermentation box body 2, and electric telescopic rods 401 are fixedly installed on both ends of the top of the side frames 4, and a top plate 402 is arranged above the two mounting plates 3, and the bottom side of the top plate 402 is fixedly connected to multiple extension columns 403 and the electric telescopic rod 401, and each extension column 403 is provided with an integrated expansion head end 405 at one end close to the heat exchange cavity tube 404.

[0044] Through the above structure, the electric telescopic rod 401 can drive the multiple heat exchange cavity tubes 404 to move vertically through the top plate 402 and the extension column 403, and can adjust the height of the mounting plate 3, and can further adjust the inclination of the multiple filter plates 302.

[0045] As a further solution of the present invention, a U-shaped plate 5 is fixedly installed on the outer wall of one side of each cavity plate 301, and a plurality of equidistantly distributed dredging holes 304 are opened at the cavity plate 301 and a position close to the U-shaped plate 5, and a corresponding arc head support rod 501 is movably penetrated inside each dredging hole 304, and the diameter of the dredging hole 304 is the same as the diameter of the filter hole of the filter plate 302.

[0046] Furthermore, each arc head support rod 501 is slidably connected to the U-shaped plate 5 , and a tensioning spring 502 is fixedly connected between one end of the arc head support rod 501 and the U-shaped plate 5 .

[0047] Through the above structure, when the height of the mounting plate 3 is lowered and the multiple filter plates 302 tend to be horizontal, the filter plates 302 are inserted into the cavity plate 301, and the multiple rows of filter holes of the filter plates 302 pass through the arc head push rods 501 in sequence, and when the filter holes are aligned with the dredging holes 304, the arc head push rods 501 are extended into the filter holes under the action of the tensioning spring 502, thereby playing a role in dredging and preventing blockage, ensuring that the leachate can fall smoothly and the leachate vapor can rise smoothly; at the same time, during the whole process, the arc head push rods 501 can continuously resist and knock the filter plates 302, so that the filter plates 302 can obtain a greater cleaning effect.

[0048] Furthermore, both sides of the liquid receiving box 1 near the bottom are fixedly connected to the slag box 101, and one end of the slag box 101 is movably connected to the plug plate 102, and two pairs of electric telescopic rods 103 are fixedly installed on the outer wall of the liquid receiving box 1, and each pair of electric telescopic rods 103 is fixedly connected to the plug plate 102 below.

[0049] Through the above structure, after the heating system has been used for a long time, when it is necessary to clean the dirt at the bottom of the receiving liquid box 1, the multiple electric telescopic rods 103 can be controlled to retract, and the two plug plates 102 can be pulled upward to move, so that the two slag boxes 101 can be opened, so that when the grid scraper 611 moves, the inner wall of the receiving liquid box 1 can be scraped and the dirt can be discharged.

[0050] As a further solution of the present invention, a steam pipe 6 is rotatably installed at one end of the two adapter pipe joints 601, and the two steam pipes 6 are fixedly connected to an external circulating steam generator. Both ends of the central axis rod 602 are fixedly penetrated by the steam pipe 6, and support brackets 8 are fixedly installed on both sides of the liquid receiving box 1, and the ends of the support brackets 8 are fixedly connected to the two ends of the central axis rod 602.

[0051] Furthermore, a gas distribution cone block 605 is fixedly installed at a position of the central axis rod 602 located inside the gas distribution plate 603, and the gas distribution cone block 605 is provided with evenly distributed steam distribution strip grooves 606.

[0052] Through the above structure, an external circulating steam generator can be used to circulate steam into multiple heat exchange branch pipes 604 through the steam pipe 6, so as to achieve heating treatment of the leachate in the docking liquid tank 1; at the same time, when the steam passes through the position of the gas separation cone block 605, part of the steam can flow under the guidance of the outer wall of the device, and the other part of the steam can be guided and circulated through the steam separation strip groove 606, which is conducive to the uniform entry of the steam into the multiple heat exchange branch pipes 604. At the same time, the collision between the steam and the gas separation plate 603 can be reduced. Finally, the set gas separation cone block 605 can form a narrow tube efficiency with the adapter pipe joint 601, which is conducive to increasing the flow rate of the steam and achieving the purpose of improving the heating effect.

[0053] Furthermore, a driving motor 7 is fixedly installed on the outer wall of one side of the liquid receiving box 1, and a driving gear 701 is fixedly installed on the output shaft of the driving motor 7, and a driven gear ring 702 is fixedly installed on the outer wall of one end of one gas distribution plate 603, and the driven gear ring 702 is meshed with the driving gear 701; through the above structure, when the driving motor 7 is controlled to operate, the transmission action of the driving gear 701 and the driven gear ring 702 can drive the gas distribution plate 603 and the multiple heat exchange branch pipes 604 to rotate.

[0054] The specific working method is as follows: when in use, first put the garbage into the fermentation box 2, and during the storage process of the garbage, the leachate therein will gradually pass through the filter plate 302 and fall into the liquid receiving box 1; an external circulating steam generator can be used to circulate steam into multiple heat exchange branch pipes 604 through the steam pipe 6, so as to achieve heating treatment of the leachate in the liquid receiving box 1; at the same time, when the steam passes through the position of the gas separation cone block 605, part of the steam circulates under the guidance of the outer wall of the device, and the other part of the steam can be guided and circulated through the steam separation strip groove 606, which is conducive to the uniform entry of the steam into the multiple heat exchange branch pipes 604, and at the same time , which can reduce the collision between steam and the gas distribution plate 603. Finally, the gas distribution cone block 605 can form a narrow tube efficiency with the adapter pipe 601, which is conducive to improving the flow rate of steam and achieving the purpose of improving the heating effect. When the leachate is heated by heat exchange with the heat exchange branch pipe 604, hot steam is generated. When it enters the heat exchange cavity tube 404, the garbage inside the fermentation box 2 is heated to ensure that it meets the fermentation temperature; and the heat exchange cavity tube 404 is used to penetrate the garbage inside the fermentation box 2, increase the heat exchange area, realize three-dimensional heating, and ensure the overall heating effect of the garbage in the fermentation box 2;

[0055] When the control driving motor 7 is running, the driving gear 701 and the driven gear ring 702 drive the gas distribution plate 603 and the multiple heat exchange branch pipes 604 to rotate. When the gas distribution plate 603 and the multiple heat exchange branch pipes 604 rotate with the central shaft rod 602 as the center, the scraper plate 609 and the reciprocating shaft sleeve 608 and the reciprocating thread end 607 are driven to rotate relative to each other, so that the scraper plate 609 can move back and forth along the reciprocating thread end 607 and scrape the outer peripheral walls of the multiple heat exchange branch pipes 604 to wipe off the scale attached to the surface, thereby ensuring the heat exchange effect between the heat exchange branch pipes 604 and the leachate;

[0056] like Figure 6 , Figure 8 as well as Fig. 9As shown in the figure, the cavity plate 301 and the filter plate 302 are arranged at an angle, which is more conducive to the flow of the leachate on the one hand, and on the other hand, the hot steam generated in the liquid receiving box 1 is more three-dimensionally in contact with the garbage inside the fermentation box 2, which is conducive to improving the heating efficiency and ensuring the fermentation effect; the electric telescopic rod 401 is arranged to drive the multiple heat exchange cavity tubes 404 to move vertically through the top plate 402 and the extension column 403, and the height of the mounting plate 3 is adjusted, and the inclination of the multiple filter plates 302 can be further adjusted. When the height of the mounting plate 3 is lowered, and the multiple filter plates 302 are adjusted, the height of the mounting plate 3 is adjusted, and the inclination of the multiple filter plates 302 is adjusted. When the plate 302 tends to be in a horizontal state, the filter plate 302 is inserted into the cavity plate 301, and the multiple rows of filter holes of the filter plate 302 pass through the arc-head push rod 501 in sequence, and when the filter holes are aligned with the dredging holes 304, the arc-head push rod 501, under the action of the tension spring 502, will extend into the filter holes, thereby playing the role of dredging and preventing clogging, ensuring that the leachate falls smoothly and the leachate vapor rises smoothly; at the same time, during the whole process, the arc-head push rod 501 constantly contacts and knocks the filter plate 302, so that the filter plate 302 has a greater cleaning effect;

[0057] After the heating system has been used for a long time, when it is necessary to clean the dirt at the bottom of the liquid receiving box 1, the multiple electric telescopic rods 103 can be controlled to retract, and the two plug plates 102 can be pulled upward to move, thereby opening the two slag boxes 101, so that when the grid scraper 611 moves, the inner wall of the liquid receiving box 1 can be scraped and the dirt can be discharged.
