Description

Technical Field

[0001] This utility model belongs to the field of incinerator technology, and in particular relates to a vertical waste treatment incinerator. Background Technology

[0002] The incineration of combustible waste constitutes a core component of the comprehensive management strategy for municipal solid waste. Currently, this step mainly relies on specific types of incinerators, which are designed for the pretreatment and efficient incineration of high-quality municipal solid waste.

[0003] However, in actual operation, existing incinerators have revealed a key problem in the ash discharge process: when the ash is discharged, it is often accompanied by a large amount of heat that is not effectively utilized. This heat is directly released into the external environment, which not only causes significant energy waste, but may also interfere with the smooth discharge of ash.

[0004] In addition, the existing feeding mechanism is often inconvenient when handling waste, which affects the efficiency of the entire process. Utility Model Content

[0005] This utility model provides a vertical waste treatment incinerator, which aims to solve the problem that existing waste incinerators suffer from large heat loss and insufficient utilization during ash discharge, resulting in energy waste and affecting the smooth discharge of ash.

[0006] This utility model is implemented as follows: a vertical waste treatment incinerator, including a furnace body;

[0007] The feeding structure provided on the side wall of the furnace body; and

[0008] A slag discharge structure located at the lower part of the furnace body;

[0009] The slag discharge structure includes:

[0010] A slag discharge channel is provided on the outer wall of the furnace body, and the slag discharge channel is connected to the furnace body;

[0011] An annular heat-absorbing groove is provided on the outside of the slag discharge channel, and the heat-absorbing groove is filled with a heat-absorbing water source.

[0012] A drying chamber and a fan are sequentially arranged at the upper part of the furnace body near the slag discharge channel;

[0013] The bottom of the drying chamber is connected to the slag discharge channel via a heat recovery pipe;

[0014] The adsorption end of the fan is connected to the drying chamber, and the exhaust end of the fan is connected to the upper part of the furnace cavity through a heat recovery pipe.

[0015] Preferably, a number of heat-conducting plates are provided on the outer side of the heat absorption tank near the slag discharge channel.

[0016] Preferably, the drying chamber is provided with a set of drying layers, and the two drying layers are distributed in parallel, one above the other.

[0017] Preferably, a one-way valve is provided on the heat recovery pipe.

[0018] Preferably, the feeding structure includes:

[0019] A feeding channel is provided on the side wall of the furnace body, and the feeding channel is connected to the furnace body;

[0020] The feeding channel is equipped with a feeding auger, and the feeding auger and the feeding channel are in a rotating fit.

[0021] Preferably, a servo motor is provided at the side end of the feeding channel, and the output end of the servo motor is fixedly connected to the end of the feeding auger.

[0022] Preferably, a temperature and humidity sensor is installed inside the drying chamber.

[0023] Preferably, the end of the slag discharge channel away from the furnace body is open, and a sealing cover is hinged to the opening.

[0024] Compared with the prior art, the embodiments of this application have the following main advantages:

[0025] Firstly, the annular heat absorption groove set outside the slag discharge channel in this device not only helps to recover heat but also reduces the temperature of the slag discharge channel. This helps to reduce the thermal stress caused by high temperature in the slag discharge channel, thereby extending its service life. At the same time, the one-way valve set on the heat recovery pipe ensures the one-way flow of heat, preventing energy loss and system instability caused by backflow of heat. In addition, the sealing cover design at the opening end of the slag discharge channel not only ensures the safe discharge of ash and slag but also further ensures the efficient recovery of heat.

[0026] Secondly, this device effectively absorbs the heat released during the slag discharge process through the setting of annular heat absorption grooves and heat conduction plates. The recovered heat is used in the drying chamber to preheat and dry the waste that is about to enter the incinerator. This not only improves the incineration efficiency, but also reduces the external energy input required during the incineration process. On the other hand, through the fan system, the hot air in the drying chamber is drawn in and carries the heat back into the furnace cavity to further participate in the incineration process, realizing the recycling of heat. This heat recovery and reuse mechanism greatly improves the energy utilization efficiency of the entire system. Attached Figure Description

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0035] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0036] This utility model embodiment provides a vertical waste treatment incinerator, such as Figure 1-6 As shown, it includes furnace body 1;

[0037] The feeding structure is provided on the side wall of the furnace body 1; and

[0038] A slag discharge structure located at the lower part of the furnace body 1;

[0039] The slag discharge structure includes:

[0040] A slag discharge channel 2 is provided on the outer wall of the furnace body 1, and the slag discharge channel 2 is connected to the furnace body 1.

[0041] An annular heat absorption groove 3 is provided on the outside of the slag discharge channel 2, and the heat absorption groove 3 is filled with a heat absorption water source.

[0042] A drying chamber 4 and a blower 5 are sequentially arranged at the upper part of the furnace body 1 adjacent to the slag discharge channel 2;

[0043] The bottom of the drying chamber 4 is connected to the slag discharge channel 2 via a heat recovery pipe 6;

[0044] The adsorption end of the fan 5 is connected to the drying chamber 4, and the exhaust end of the fan 5 is connected to the upper part of the inner cavity of the furnace body 1 through the heat recovery pipe 6.

[0045] It should be noted that existing waste incinerators suffer from significant heat loss and underutilization during ash discharge, leading to energy waste and hindering smooth ash discharge. This solution effectively recovers heat during ash discharge by combining annular heat-absorbing groove 3 with heat-conducting plate 7, reintroducing hot air from drying chamber 4 into furnace body 1, achieving heat recycling and significantly improving the energy efficiency of the entire system. Meanwhile, the one-way valve 9 ensures unidirectional heat flow, preventing energy loss and system instability. The sealing cover 14 at the opening of ash discharge channel 2 ensures safe ash discharge and efficient heat recovery. This series of designs, working together, not only extends the equipment's service life but also greatly enhances system stability and energy efficiency, achieving a dual optimization of environmental protection and economy.

[0046] Specifically, in this embodiment, the solution mainly includes a furnace body 1, a feeding structure, and a slag discharge structure; during the incineration process, waste is fed into the furnace body 1 through the feeding structure for combustion; as combustion proceeds, the generated ash and slag gradually accumulate in the lower part of the furnace body 1.

[0047] When the ash and slag accumulate to a certain extent, they will be discharged through the slag discharge channel 2 on the outer wall of the furnace body 1. The slag discharge channel 2 is connected to the inside of the furnace body 1 to ensure that the ash and slag can be discharged smoothly. An annular heat absorption groove 3 is set at the outside of the slag discharge channel 2. The heat absorption groove 3 is filled with a heat absorption water source to absorb the heat released during the slag discharge process. This can not only improve the heat utilization rate, but also reduce the temperature of the slag discharge channel 2 and extend its service life.

[0048] Meanwhile, a drying chamber 4 and a blower 5 are installed at the upper part of the furnace body 1 near the slag discharge channel 2; the bottom of the drying chamber 4 is connected to the slag discharge channel 2 through a heat recovery pipe 6; in this way, the heat in the slag discharge channel 2 can be recovered and used in the drying chamber 4.

[0049] The adsorption end of the blower 5 is connected to the drying chamber 4, drawing in the hot air from the drying chamber 4. Then, the exhaust end of the blower 5 is connected to the upper part of the inner cavity of the furnace body 1 through another heat recovery pipe 6. In this way, the air drawn in can carry heat back into the inner cavity of the furnace body 1 and further participate in the combustion process, realizing the recycling of heat.

[0050] In a further preferred embodiment of this utility model, such as Figure 3 As shown, a number of heat-conducting plates 7 are provided on the outside of the heat absorption tank 3 near the slag discharge channel 2.

[0051] In this embodiment, the heat-conducting plate 7 has excellent thermal conductivity and is closely attached to the outer wall of the heat-absorbing tank 3, forming an effective heat exchange interface with the ash in the ash discharge channel 2. When the ash passes through the ash discharge channel 2, the heat it carries is quickly transferred to the heat-absorbing water source in the heat-absorbing tank 3 through the heat-conducting plate 7.

[0052] In a further preferred embodiment of this utility model, such as Figure 3 As shown, a set of drying layers 8 are provided in the drying chamber 4, and the two drying layers 8 are distributed in parallel, one above the other.

[0053] In this embodiment, the lower drying layer 8 initially adsorbs moisture from the recovered hot gas. The recovered hot gas continues to rise into the upper drying layer 8 as it is adsorbed by the fan 5. Here, the heat transfer is more thorough, further removing moisture from the waste and bringing it to a state more suitable for incineration.

[0054] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, a one-way valve 9 is installed on the heat recovery pipe 6.

[0055] In this embodiment, a one-way valve 9 is installed on the heat recovery pipe 6 to ensure that heat can only flow in one direction, that is, only from the heat absorption tank 3 to the drying chamber 4, and then from the drying chamber 4 to the inner cavity of the furnace body 1 through the fan 5 system. This effectively prevents heat backflow and avoids energy loss and system instability.

[0056] In a further preferred embodiment of this utility model, such as Figure 1-4 As shown, the feeding structure includes:

[0057] A feeding channel 10 is provided on the side wall of the furnace body 1, and the feeding channel 10 is connected to the furnace body 1.

[0058] The feeding channel 10 is equipped with a feeding auger 11, and the feeding auger 11 and the feeding channel 10 are in a rotating fit.

[0059] In this embodiment, waste is fed into the feeding channel 10, and the spiral blades of the feeding auger 11 begin to rotate, pushing the waste along the feeding channel 10 into the furnace body 1. Due to the close cooperation between the feeding auger 11 and the feeding channel 10, the waste can be transported continuously and stably. When the waste is pushed to the outlet end of the channel, it will directly enter the furnace body 1 for incineration.

[0060] In a further preferred embodiment of this utility model, such as Figure 4 As shown, a servo motor 12 is provided on the side end of the feeding channel 10, and the output end of the servo motor 12 is fixedly connected to the end of the feeding auger 11.

[0061] In this embodiment, the servo motor 12 transmits power to the feeding auger 11 through a keyed connection, causing it to start rotating.

[0062] In a further preferred embodiment of this utility model, such as Figure 3 As shown, a temperature and humidity sensor 13 (PT100) is installed inside the drying chamber 4.

[0063] In this embodiment, through continuous monitoring and adjustment, the temperature and humidity inside the drying chamber 4 can be maintained within the optimal range, providing favorable conditions for the subsequent incineration process of the waste.

[0064] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, the end of the slag discharge channel 2 away from the furnace body 1 is open, and a sealing cover 14 is hinged to the opening.

[0065] In this embodiment, by hinged and fitted with a sealing cover 14 at the opening end of the slag discharge channel 2, safe discharge of ash and efficient heat recovery are achieved.

[0066] Working principle: When this device is in use, waste is put into the feeding channel 10; then, the servo motor 12 drives the spiral blades of the feeding auger 11 to start rotating. With the close cooperation between the auger and the feeding channel 10, the waste is continuously and stably pushed into the furnace body 1 along the channel; when the waste is pushed to the outlet end of the channel, it enters the furnace body 1 and the incineration process begins.

[0067] Inside the furnace body 1, the waste undergoes an incineration process, and the resulting ash gradually accumulates in the lower part of the furnace body 1. When the ash accumulates to a certain extent, it will be discharged through the ash discharge channel 2 on the outer wall of the furnace body 1. The ash discharge channel 2 is closely connected to the interior of the furnace body 1 to ensure the smooth discharge of ash.

[0068] An annular heat-absorbing groove 3 is installed outside the slag discharge channel 2, and the heat-absorbing groove 3 is filled with a heat-absorbing water source. The main function of the heat-absorbing groove 3 is to absorb the heat released during the slag discharge process, thereby improving the heat utilization rate and effectively reducing the temperature of the slag discharge channel 2 and extending its service life. In order to achieve efficient heat exchange, the heat-conducting plate 7 is tightly attached to the outer wall of the heat-absorbing groove 3, forming an effective heat exchange interface with the ash and slag in the slag discharge channel 2. When the ash and slag pass through the slag discharge channel 2, the heat it carries is quickly transferred to the heat-absorbing water source in the heat-absorbing groove 3 through the heat-conducting plate 7.

[0069] Meanwhile, a drying chamber 4 and a blower 5 are configured at the upper part of the furnace body 1 near the slag discharge channel 2. The bottom of the drying chamber 4 is connected to the slag discharge channel 2 through a heat recovery pipe 6, so that the heat in the slag discharge channel 2 can be recovered and used in the drying chamber 4. The adsorption end of the blower 5 is connected to the drying chamber 4, drawing in the hot air from the drying chamber 4. Its discharge end is connected to the upper part of the inner cavity of the furnace body 1 through another heat recovery pipe 6. In this way, the air that is drawn in carries heat and re-enters the inner cavity of the furnace body 1 to further participate in the combustion process, realizing the recycling of heat.

[0070] Inside the drying chamber 4, there are two drying layers 8, one above the other. The lower drying layer 8 performs preliminary moisture adsorption on the recovered hot air, and then the hot air continues to rise into the upper drying layer 8 with the adsorption of the fan 5. Here, the heat transfer is more complete, further removing the moisture from the waste and making it more suitable for incineration.

[0071] To ensure the unidirectional flow of heat and prevent energy loss and system instability caused by backflow of heat, a one-way valve 9 is installed on the heat recovery pipe 6. The one-way valve 9 ensures that heat can only flow from the heat absorption tank 3 to the drying chamber 4, and then from the drying chamber 4 to the inner cavity of the furnace body 1 through the fan 5 system.

However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
