Technical Field
[0001] This utility model relates to the field of waste heat recovery technology, specifically a novel waste heat energy-saving recovery device for waste liquid incinerators. Background Technology
[0002] A waste liquid incinerator is a specialized device for incinerating and treating liquid waste. Its main function is to oxidize harmful substances in waste liquid into carbon dioxide and water through high-temperature incineration, thereby achieving environmentally compliant emissions. Waste liquid incinerators are typically used to treat hazardous organic waste liquids. These waste liquids undergo a controlled high-temperature chemical reaction process within the incinerator's combustion chamber, breaking down their molecular structure and achieving environmentally friendly treatment. During the incineration process, waste liquid incinerators generate a significant amount of waste heat, which usually needs to be recovered through preheating to save energy.
[0003] Existing methods for recovering waste heat from waste liquid incinerators cannot simultaneously recover the heat contained in the incinerator and the waste gas, and the preheating and recovery of the waste gas can easily cause obstruction of waste gas discharge. Therefore, they do not meet the current needs. To address this, we propose a new type of waste heat energy-saving recovery device for waste liquid incinerators. Utility Model Content
[0004] The purpose of this utility model is to provide a novel waste heat energy-saving recovery device for waste liquid incinerators, in order to solve the problems mentioned in the background art, such as the inability to simultaneously recover the heat contained in the incinerator and the waste gas during the waste heat recovery process, and the easy occurrence of obstructed waste gas discharge during waste gas preheating recovery.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel waste heat energy-saving recovery device for a waste liquid incinerator, comprising an isolation cover, a first exhaust pipe fixedly installed at the upper part of the rear end of the isolation cover, an isolation sleeve fixedly installed on the inner side of the isolation cover, a flow-slowing ring installed at the front end of the isolation sleeve, a flow-slowing cavity provided between the isolation sleeve and the flow-slowing ring, multiple flow-blocking rings fixedly installed on the outer side of the flow-slowing ring, multiple heat exchange plates installed in the middle of the isolation sleeve, multiple contact grooves provided on the surface of the heat exchange plates, a flow-diverting ring installed at the front end of the multiple heat exchange plates, liquid delivery pipes installed at both the upper and lower ends of the flow-diverting ring, a liquid storage tank fixedly installed in the middle of the rear end of the isolation cover, a heat-conducting sleeve fixedly installed on the inner side of the liquid storage tank, and multiple contact fins provided on the outer surface of the heat-conducting sleeve.
[0006] Preferably, a furnace body is installed on the inner side of the isolation sleeve, a feed end is fixedly installed at the front end of the furnace body, the isolation cover is fixedly connected to the furnace body through the feed end, and a second exhaust pipe is fixedly installed at the upper part of the rear end of the furnace body.
[0007] Preferably, the first exhaust pipe and the second exhaust pipe are coaxial, the isolation sleeve is inserted between the first exhaust pipe and the second exhaust pipe, the front end of the flow-damping ring is fixedly connected to the isolation cover, the rear end of the flow-damping ring is inserted into the inner side of the front end of the isolation sleeve, and the plurality of flow-damping rings are arranged linearly along the axis of the flow-damping ring, and the diameter of the plurality of flow-damping rings decreases sequentially from front to back along the axis of the flow-damping ring.
[0008] Preferably, the isolation sleeve is fixedly connected to the diversion ring and multiple heat exchange plates, the multiple heat exchange plates are arranged circumferentially relative to the axis of the isolation sleeve, and the two infusion tubes pass through the isolation cover and are connected to the multiple heat exchange plates through the diversion ring.
[0009] Preferably, a heat exchange chamber is provided between the liquid storage tank and the heat-conducting sleeve, and the heat-conducting sleeve is connected to the interior of the furnace body.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. In this utility model, the first exhaust pipe and the second exhaust pipe are coaxial, and a flow-slowing cavity is provided between the isolation sleeve and the flow-slowing ring. This allows the high-temperature gas discharged from the second exhaust pipe to be guided and diverted through the isolation sleeve, so that the high-temperature gas can fully contact the surface of the heat exchange plate. At the same time, multiple flow-blocking rings are fixedly installed on the outside of the flow-slowing ring in a linear arrangement. The number of flow-blocking rings decreases from front to back along the axis of the flow-slowing ring. Thus, the flow rate of the high-temperature gas can be effectively reduced by passing through multiple flow-blocking rings during the diversion process in the flow-slowing cavity.
[0012] 2. This utility model has multiple contact grooves on the surface of the heat exchange sleeve, which can effectively improve the heat exchange contact degree between the heat exchange sleeve and the high-temperature gas. When the liquid delivery pipe injects water into the multiple heat exchange sleeves through the diversion ring and circulates, it can achieve a high-efficiency recovery effect of waste heat from the waste liquid incinerator. At the same time, the heat-conducting sleeve is connected to the furnace body, so that the heat-conducting sleeve can exchange heat with the water inside the liquid storage tank through multiple contact fins, thereby realizing the waste heat recovery treatment of both the heat of the waste liquid incinerator itself and the heat of the gas.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Please see Figures 1 to 3 This utility model provides an embodiment of a novel waste heat recovery device for a waste liquid incinerator, comprising an isolation cover 1, a first exhaust pipe 4 fixedly installed at the upper rear end of the isolation cover 1, an isolation sleeve 8 fixedly installed inside the isolation cover 1, a furnace body 5 installed inside the isolation sleeve 8, a feed end 2 fixedly installed at the front end of the furnace body 5, the isolation cover 1 and the furnace body 5 being fixedly connected via the feed end 2, a second exhaust pipe 6 fixedly installed at the upper rear end of the furnace body 5, the first exhaust pipe 4 and the second exhaust pipe 6 being coaxial, the isolation sleeve 8 being inserted between the first exhaust pipe 4 and the second exhaust pipe 6, the furnace body 5 being fed through the feed end 2 to achieve waste liquid incineration treatment, and the high-temperature gas being discharged through the second exhaust pipe 6.
[0021] Please see Figure 3 and Figure 5 A flow-slowing ring 7 is installed at the front end of the isolation sleeve 8. A flow-slowing cavity 9 is provided between the isolation sleeve 8 and the flow-slowing ring 7. Multiple flow-blocking rings 16 are fixedly installed on the outer side of the flow-slowing ring 7. The front end of the flow-slowing ring 7 is fixedly connected to the isolation cover 1. The rear end of the flow-slowing ring 7 is inserted into the inner side of the front end of the isolation sleeve 8. The multiple flow-blocking rings 16 are arranged linearly along the axis of the flow-slowing ring 7. The diameter of the multiple flow-blocking rings 16 decreases sequentially from front to back along the axis of the flow-slowing ring 7.
[0022] Please see Figure 3 and Figure 5Multiple heat exchange plates 10 are installed in the middle of the isolation sleeve 8. Multiple contact grooves 15 are provided on the surface of the heat exchange plates 10. A diversion ring 14 is installed at the front end of the multiple heat exchange plates 10. Infusion pipes 3 are installed at both the upper and lower ends of the diversion ring 14. The isolation sleeve 8 is fixedly connected to the diversion ring 14 and the multiple heat exchange plates 10. The multiple heat exchange plates 10 are arranged in a circle relative to the axis of the isolation sleeve 8. Two infusion pipes 3 pass through the isolation cover 1 and are connected to the multiple heat exchange plates 10 through the diversion ring 14. The high-temperature gas discharged from the second exhaust pipe 6 can be guided and reversed through the isolation sleeve 8, so that the high-temperature gas can fully contact the surface of the heat exchange plates 10. The contact grooves 15 can effectively improve the heat exchange contact degree of the heat exchange plates 10 with the high-temperature gas.
[0023] Please see Figure 3 and Figure 4 A liquid storage tank 11 is fixedly installed in the middle of the rear end of the isolation cover 1. A heat-conducting sleeve 12 is fixedly installed on the inner side of the liquid storage tank 11. The outer surface of the heat-conducting sleeve 12 is provided with multiple contact fins 13. A heat exchange chamber is provided between the liquid storage tank 11 and the heat-conducting sleeve 12. The heat-conducting sleeve 12 is connected to the interior of the furnace body 5. The heat-conducting sleeve 12 can exchange heat with the water inside the liquid storage tank 11 through multiple contact fins 13, thereby realizing the waste heat recovery treatment of both the heat of the waste liquid incinerator itself and the heat of the gas.
[0024] In summary, when recovering the waste heat from the waste liquid incinerator, the isolation cover 1 is fitted and fixed on the outside of the furnace body 5, so that the first exhaust pipe 4 and the second exhaust pipe 6 are coaxial. When the power is turned on, the furnace body 5 is filled with material through the feed end 2 to realize the incineration treatment of the waste liquid and the high temperature gas is discharged through the second exhaust pipe 6. The isolation sleeve 8 is inserted between the first exhaust pipe 4 and the second exhaust pipe 6 and fitted on the outside of the rear end of the slow flow ring 7. A slow flow cavity 9 is provided between the isolation sleeve 8 and the slow flow ring 7, so that the high temperature gas discharged from the second exhaust pipe 6 can be guided and reversed through the isolation sleeve 8, so that the high temperature gas can fully contact the surface of the heat exchange sleeve 10.
[0025] Meanwhile, multiple flow-blocking rings 16 arranged linearly are fixedly installed on the outside of the flow-slowing ring 7, and the number of flow-blocking rings 16 decreases sequentially from front to back along the axis of the flow-slowing ring 7. Thus, during the reversal process of the high-temperature gas in the flow-slowing cavity 9, the flow rate can be effectively reduced by passing through multiple flow-blocking rings 16. Multiple contact grooves 15 are provided on the surface of the heat exchange sleeve 10, so that the heat exchange contact degree of the heat exchange sleeve 10 with the high-temperature gas can be effectively improved through the contact grooves 15.
[0026] Furthermore, when the infusion pipe 3 injects water into multiple heat exchange plates 10 through the diversion ring 14 and circulates, it can achieve a high-efficiency recovery effect of waste heat from the waste liquid incinerator. At the same time, the heat-conducting sleeve 12 is connected to the furnace body 5, so that the heat-conducting sleeve 12 can exchange heat with the water inside the storage tank 11 through multiple contact fins 13, thereby realizing the waste heat recovery treatment of both the heat of the waste liquid incinerator itself and the heat of the gas.
