[0002] In a garbage treatment plant, incineration is one of the main ways to deal with garbage. However, during the incineration process, the water content in the garbage is high, and a large amount of leachate will be produced. Generally, the leachate treatment station set up in the plant can treat it to meet the emission standards. However, during the leachate treatment process, concentrated liquid will be produced, which needs to be evaporated through the concentrated liquid return spray chamber. The existing concentrated liquid return spray chamber atomizes and sprays the concentrated liquid when in use, and uses the high temperature in the combustion chamber to evaporate the atomized concentrated liquid. The evaporation effect is limited. Therefore, we propose a concentrated liquid return spray furnace that can quickly evaporate the concentrated liquid.

The existing technology has the following problems: the existing concentrated liquid is only sprayed out through an atomizing nozzle during processing, and is evaporated by taking advantage of the heat in the combustion chamber. The evaporation method is single and the evaporation effect is limited. Utility Model Content

The auxiliary evaporation chambers are distributed on both sides of the main evaporation chamber; when in use, the bottom opening of the furnace body 1 is connected to the external combustion chamber to allow the heat in the combustion chamber to enter the furnace body 1. After the hot air enters the furnace body 1, most of the heat will pass through the middle main evaporation chamber, and some of the hot air will enter the auxiliary evaporation chamber. An outlet is provided above the auxiliary evaporation chamber to reconnect with the main evaporation chamber. The main evaporation chamber mainly evaporates the small droplets of concentrated liquid sprayed by the atomizing nozzle 503, while the auxiliary evaporation chamber evaporates the concentrated liquid film falling from the inner wall of the evaporation tube 502. The double evaporation effect is better. If some of the concentrated liquid is not completely evaporated, it will rise with the hot air, be blocked after touching the inner wall of the butterfly cover 2, flow into the annular groove 3 along the inner wall of the butterfly cover 2, and flow into the concentrated liquid tank 501 from the first pipe 4 on the rear side of the annular groove 3 to continue to circulate and evaporate until the concentrated liquid is completely evaporated.

[0027] In this embodiment, Figure 2 , Figure 3-Figure 4 , Figure 6-Figure 8As shown, the evaporation assembly 5 includes two concentrated liquid tanks 501 respectively fixedly connected to the inside of the two installation chambers 8, the bottoms of the two concentrated liquid tanks 501 are respectively connected to three evaporation tubes 502, the bottom ends of the three evaporation tubes 502 are all connected to the atomizing nozzles 503 through the partition 6, the two concentrated liquid tanks 501 are connected through the second pipeline 9, the top surface of the concentrated liquid tank 501 is penetrated by three fixing rods 504, the top ends of the three fixing rods 504 are connected by a fixing plate 505, and the fixed The fixed plate 505 is embedded in the top surface of the installation cavity 8. The bottom ends of the three fixing rods 504 are fixedly connected with fixing rings 5014. The fixing rings 5014 penetrate the middle straight grooves of the plurality of adjusting rings 5015. The inner sides of the top ends of the plurality of adjusting rings 5015 are hinged with the threaded tube 506. The inner wall of the threaded tube 506 is threadedly connected with the outer side of the adjusting screw 507. The outer sides of the plurality of adjusting rings 5015 are attached with soft liquid cloth films 5013. The top ends of the adjusting screws 507 are fixedly connected with the fixing rings 5014. A sub-gear 508 is fixedly connected, and a main gear 509 is meshed on one side of the sub-gear 508. The main gear 509 is fixedly connected to the output end of the motor 5010, and the motor 5010 is fixedly connected to the middle of the top surface of the concentrate tank 501. The outer side of the threaded cylinder 506 is fixedly connected to two guide plates 5011, and the two guide plates 5011 are respectively slidably connected to the middle of two guide grooves 5012. The guide grooves 5012 are set on the inner wall surface of the hole on the bottom of the concentrate tank 501. The threaded cylinder 506 The middle of the threaded barrel 506 and the adjusting screw 507 are provided with through holes, the fixing rod 504 penetrates through the middle through holes of the threaded barrel 506 and the adjusting screw 507, and the fixing rod 504, the threaded barrel 506 and the adjusting screw 507 are not in contact with each other, three threaded barrels 506 are provided in the concentrate tank 501, and the three threaded barrels 506 correspond to the three evaporation tubes 502 respectively, and the adjusting ring 5015 and the soft liquid cloth film 5013 at the bottom end of the threaded barrel 506 are located at the inner top of the evaporation tube 502;The concentrated liquid in the concentrate tank 501 can flow into the evaporation tube 502 through the holes on the bottom surface of the concentrate tank 501. The concentrated liquid will form a liquid film along the inner wall of the evaporation tube 502 and flow downward. The evaporation tube 502 is heated by the high temperature in the auxiliary evaporation chamber and has a very high temperature. Therefore, the concentrated liquid on the inner wall can be evaporated for the first time. Part of the concentrated liquid that has not been completely evaporated will continue to fall to the position of the atomizing nozzle 503 and be sprayed into the main evaporation chamber. It will be evaporated for the second time at the high temperature in the main evaporation chamber. The double evaporation effect is better, and the evaporation tube 502 has a higher temperature for the concentrated liquid. The evaporation effect of the liquid is directly affected by the thickness of the liquid film on the inner wall of the evaporation tube 502. The thinner the liquid film, the better the evaporation effect. Therefore, when it is necessary to adjust the thickness of the liquid film on the inner wall of the evaporation tube 502, the start motor 5010 drives the main gear 509 to rotate, and the main gear 509 drives the adjusting screw 507 to rotate through the sub-gear 508. The adjusting screw 507 is rotatably connected to the top of the concentrated liquid tank 501. Therefore, when the adjusting screw 507 rotates, it can drive the threaded barrel 506 to rise and fall. The threaded barrel 506 threadedly connected to the adjusting screw 507 is The main cylinder is the main cylinder, and the rest are auxiliary cylinders. The main cylinder and the auxiliary cylinder are connected by a cross bar. When the main cylinder in the threaded cylinder 506 is lifted or lowered, the cross bar and the guide plate 5011 are simultaneously driven to lift or lower. At this time, the guide plate 5011 is located in the middle of the guide groove 5012 and slides, making the lifting of the threaded cylinder 506 more stable, and the cross bar can drive the two auxiliary cylinders to lift or lower synchronously. Taking the lowering of the threaded cylinder 506 as an example, the threaded cylinder 506 will drive several adjusting rings 5015 and the soft liquid cloth membrane 5013 at the bottom to lift or lower synchronously, while the fixing ring 5014 and the fixing plate 505 at the top are Therefore, the height of the fixed ring 5014 remains unchanged. When the adjusting ring 5015 descends, the fixed ring 5014 moves relatively. The fixed ring 5014 moves upward in the straight notch in the middle of the adjusting ring 5015, so that the bottom end of the adjusting ring 5015 opens outward, thereby expanding the bottom surface of the soft liquid distribution film 5013, reducing the gap between the soft liquid distribution film 5013 and the inner wall of the evaporation tube 502, and achieving the purpose of adjusting the thickness of the concentrated liquid film on the inner wall of the evaporation tube 502. Conversely, the thickness of the concentrated liquid film on the inner wall of the evaporation tube 502 can be increased by the same reasoning. ;

[0028] The use method and advantages of the utility model: When the concentrated liquid spraying furnace chamber capable of rapidly evaporating the concentrated liquid is used, the working process is as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, first, the bottom opening of the furnace body 1 is connected to the external combustion chamber, and then the heat in the combustion chamber will enter the main evaporation chamber and the auxiliary evaporation chamber inside the furnace body 1, and then the concentrated liquid in the concentrated liquid tank 501 will be sprayed out from the atomizing nozzle 503 through the evaporation component 5, and the atomizing nozzle 503 will atomize the concentrated liquid and spray it into the main evaporation chamber for evaporation, and the auxiliary evaporation chamber can evaporate the concentrated liquid on the inner wall of the evaporation tube 502, and the double evaporation effect is better, wherein the concentrated liquid that is not completely evaporated will rise and contact the inner wall of the butterfly cover 2, and flow into the annular groove 3 along the inner wall of the butterfly cover 2, and finally flow back to the concentrated liquid tank 501 through the first pipeline 4, forming a cycle until the concentrated liquid is completely evaporated, and when it is necessary to change the thickness of the liquid film on the inner wall of the evaporation tube 502 When the evaporation effect of the concentrated liquid in the evaporation tube 502 is changed, the motor 5010 is used to drive and drive the adjusting screw 507 to rotate. The rotation of the adjusting screw 507 will drive the several adjusting rings 5015 and the soft liquid cloth membrane 5013 at the bottom to rise and fall synchronously through the threaded tube 506. When the adjusting ring 5015 descends, the fixed ring 5014 will move relatively. The fixed ring 5014 moves upward in the straight groove in the middle of the adjusting ring 5015, so that the bottom end of the adjusting ring 5015 opens outward, thereby expanding the bottom surface of the soft liquid cloth membrane 5013 and reducing the gap between the soft liquid cloth membrane 5013 and the inner wall of the evaporation tube 502, so as to achieve the purpose of adjusting the thickness of the concentrated liquid film on the inner wall of the evaporation tube 502.
