Description

Technical Field

[0001] This utility model belongs to the field of incinerator technology, and in particular relates to an air distribution device for an incinerator. Background Technology

[0002] Excessive combustion air is introduced into the incinerator to support the combustion of materials. Existing incinerators directly send the combustion air into their combustion chamber, which means that impurities in the air, such as particulate matter, dust, and other pollutants, are not effectively removed before entering the incinerator. These impurities not only affect the stability and efficiency of the incineration process and reduce combustion efficiency, but may also react chemically with the exhaust gases produced by incineration at high temperatures to generate even more harmful substances. These harmful substances pose a great threat to the environment and human health.

[0003] Secondly, existing incinerator designs also have significant shortcomings in terms of heat recovery and utilization. These designs typically focus only on the incineration process itself, neglecting the recovery of heat from the flue gas. Before a large amount of high-temperature flue gas is released into the atmosphere, the heat in it is not fully utilized, resulting in low energy efficiency. This not only increases the operating cost of the incinerator, as more energy is required to maintain the incineration process, but also causes unnecessary thermal pollution and energy waste to the environment. Utility Model Content

[0004] This utility model provides an air distribution device for an incinerator, which aims to solve the problems of insufficient air filtration in existing incinerators, which leads to impurities affecting incineration efficiency and generating harmful substances; secondly, insufficient heat recovery and utilization, resulting in low energy efficiency and thermal pollution.

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.

[0035] This utility model embodiment provides an air distribution device for an incinerator, such as Figure 1-6 As shown, it includes furnace body 1;

[0036] The air distribution structure is located on the side wall of the furnace body 1;

[0037] The air distribution structure includes:

[0038] Air distribution chamber 2 is located in the lower part of the outer side of furnace body 1;

[0039] An annular preheating jacket 3 is fitted on the outside of the air distribution chamber 2, and an annular flow channel 4 is opened inside and filled with heat transfer oil.

[0040] A preheating pipe 5 is connected between the furnace body 1 and the preheating jacket 3, and its flow direction is 180° opposite to the flue gas flow direction.

[0041] A fan 6 is installed at the end of the air distribution chamber 2 away from the furnace body 1. The air intake port of the fan 6 is equipped with a filter structure, and the air outlet port of the fan 6 is connected to the air distribution chamber 2.

[0042] A mounting base 7 is provided at the connection between the air distribution chamber 2 and the furnace body 1;

[0043] On the side of the mounting base 7 opposite to the furnace body 1, there is an air distribution nozzle 8 that is connected to the air distribution chamber 2. The nozzles of the air distribution nozzle 8 are inclined upwards.

[0044] It should be noted that existing incinerators suffer from insufficient air filtration, leading to impurities affecting combustion efficiency and generating harmful substances. Secondly, insufficient heat recovery and utilization result in low energy efficiency and thermal pollution. This solution, through the design of the preheating conduit 5, successfully achieves efficient recovery and utilization of heat from the high-temperature flue gas within the furnace body 1. The heat transfer oil in the preheating jacket 3 effectively absorbs and utilizes this heat to preheat the air in the air distribution chamber 2, significantly improving preheating efficiency and greatly reducing heat loss, making the entire combustion process more energy-efficient. Simultaneously, the precise adjustment function of the independent control valve 16 ensures stable operation of the heat transfer oil within a suitable temperature range, effectively avoiding overheating or insufficient heat, further enhancing the safety and stability of the preheating process. Furthermore, the adsorption port of the device's fan 6 is equipped with an advanced filter box 9. Before entering the air distribution chamber 2, the air undergoes dual filtration through a primary filter 10 and an activated carbon layer 11. These two layers of filter materials work closely together to efficiently remove various impurities from the air, ensuring that the air entering the air distribution chamber 2 is pure and free of impurities, thereby improving the purity of the air before it enters the air distribution chamber 2.

[0045] Specifically, in this embodiment, the solution mainly includes a furnace body 1; after the device is started, the blower 6 starts to work; the air intake port of the blower 6 draws in external air through the filter structure to ensure that the air entering the device is clean and free of impurities; subsequently, the filtered air is sent into the air distribution chamber 2 by the blower 6.

[0046] Outside the air distribution chamber 2, an annular preheating jacket 3 is fitted. The preheating jacket 3 has an annular flow channel 4 inside and is filled with heat transfer oil. The preheating pipe 5 connects the furnace body 1 and the preheating jacket 3, and its flow direction is 180° opposite to the flue gas flow direction. In this way, the high-temperature flue gas generated in the furnace body 1 can transfer heat to the heat transfer oil in the preheating jacket 3 through the preheating pipe 5, so that the heat transfer oil is heated.

[0047] After the heat transfer oil is heated, its heat will be transferred to the air in the air distribution chamber 2, thereby preheating the air; the preheated air has higher energy and better combustion effect;

[0048] Next, the preheated and pressurized air enters the air distribution nozzle 8, which is connected to the air distribution chamber 2, through the mounting base 7 at the connection between the air distribution chamber 2 and the furnace body 1. The nozzles of the air distribution nozzle 8 are inclined upwards, which allows the air to be sprayed into the furnace body 1 at a certain angle.

[0049] The air injected into the furnace body 1 can be more evenly distributed throughout the furnace chamber, and fully mixed with the fuel in the furnace chamber, improving combustion efficiency and combustion uniformity; at the same time, since the air has been preheated, its combustion effect is better, which helps to reduce fuel consumption and reduce emissions.

[0050] In a further preferred embodiment of this utility model, such as Figure 4-5 As shown, the filter structure includes:

[0051] Filter box 9 is connected to the adsorption port of fan 6;

[0052] A primary filter 10 and an activated carbon layer 11 are sequentially arranged on the air inlet side of the filter box 9.

[0053] In this embodiment, the air intake port of the fan 6 is connected to the filter box 9, so the outside air first enters the filter box 9; on the air intake side of the filter box 9, the air will pass through the pre-filter 10 and the activated carbon layer 11 in sequence.

[0054] The pre-filter 10 can block and filter out large particles of dust and impurities in the air, ensuring that the air entering the subsequent filtration stage is relatively clean. Then, the air filtered by the pre-filter 10 will enter the activated carbon layer 11. The activated carbon layer 11 has a strong adsorption capacity, which can further adsorb and remove fine particles, harmful gases and odors in the air, thereby providing purer air to the fan 6. The fan 6 will draw in the clean air after double filtration and send it into the air distribution chamber 2.

[0055] In a further preferred embodiment of this utility model, such as Figure 4-5 As shown, a temperature sensor 12 and a pressure sensor 13 are installed on the connection surface between the air distribution chamber 2 and the furnace body 1.

[0056] In this embodiment, temperature sensor 12 (TC-K-1-1200) is used to monitor the temperature of the air in the air distribution chamber 2 in real time to ensure that the preheated air reaches the ideal combustion temperature, thereby improving combustion efficiency. At the same time, pressure sensor 13 (APC-3050-060) is used to monitor the pressure change at the connection between the air distribution chamber 2 and the furnace body 1 to ensure that the air can enter the furnace body 1 stably and evenly, and avoid pressure fluctuations from adversely affecting the combustion process.

[0057] In a further preferred embodiment of this utility model, such as Figure 4 As shown, a graphene sealing gasket 14 is provided at the connection between the air distribution chamber 2 and the furnace body 1.

[0058] In this embodiment, the graphene sealing gasket 14, with its high temperature resistance, corrosion resistance, and toughness, ensures the tightness of the connection, effectively preventing air leakage and corrosion of the connector by high-temperature flue gas, thereby extending the service life of the device.

[0059] In a further preferred embodiment of this utility model, such as Figure 4-5 As shown, a pressure relief pipe assembly 15 is provided on the top side of the furnace body 1 and is connected to it. The pressure relief pipe assembly 15 is connected to the furnace body 1 by a quick-release clamp.

[0060] In this embodiment, the pressure relief pipe assembly 15 is connected to the furnace body 1 using a quick-release clamp. This connection method not only facilitates installation and disassembly, but also ensures that the pressure inside the furnace body 1 can be quickly released when needed, guaranteeing the safe operation of the incinerator. At the same time, the quick-release clamp connection also has good sealing performance, effectively preventing the leakage of flue gas inside the furnace body 1.

[0061] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, the preheating conduit 5 is a ceramic fiber insulated pipe.

[0062] In this embodiment, the preheating conduit 5 is made of ceramic fiber insulation pipe. This material has excellent high temperature resistance and heat insulation performance, and can effectively transfer the heat of high temperature flue gas in the furnace body 1 to the heat transfer oil in the preheating jacket 3, thereby preheating the air in the air distribution chamber 2.

[0063] In a further preferred embodiment of this utility model, such as Figure 4-5 As shown, an independent control valve 16 is installed on the preheating conduit 5.

[0064] In this embodiment, this design allows the operator to precisely control the opening and closing of the preheating conduit 5 and adjust the heat transfer rate during the preheating process. By adjusting the independent control valve 16, it can be ensured that the heat transfer oil in the preheating jacket 3 operates within an appropriate temperature range, thereby avoiding overheating or underheating and further improving preheating efficiency and safety.

[0065] In a further preferred embodiment of this utility model, such as Figure 4-5 As shown, a PLC controller 17 is installed on the bottom side of the air distribution chamber 2, which is electrically connected to the independent control valve 16, the temperature sensor 12 and the pressure sensor 13.

[0066] In this embodiment, the PLC controller 17 can receive signals from the temperature sensor 12 and the pressure sensor 13 in real time, and precisely control the independent control valve 16 according to the preset program and algorithm. Through the intelligent adjustment of the PLC controller 17, the heat of the preheating conduit 5, the real-time monitoring and adjustment of the air temperature in the air distribution chamber 2, and the stable control of the pressure in the furnace body 1 can be realized, thereby ensuring the stable operation and efficient combustion of the incinerator.

[0067] Working principle: When this device is in use, the fan 6 starts to operate; the air intake port of the fan 6 is connected to the filter box 9, and the outside air first enters the filter box 9; on the air intake side of the filter box 9, the air will pass through the pre-filter 10 and the activated carbon layer 11 in sequence. The two layers of filtration structure work together to ensure that the air entering the fan 6 is clean and free of impurities.

[0068] The blower 6 draws in clean air that has undergone double filtration and sends it into the air distribution chamber 2. The outer side of the air distribution chamber 2 is fitted with an annular preheating sleeve 3. The preheating sleeve 3 has an annular flow channel 4 inside and is filled with heat-conducting oil. In order to improve the preheating efficiency and reduce heat loss, the preheating conduit 5 is made of ceramic fiber insulation pipe. This material has excellent high temperature resistance and heat insulation performance, and can effectively transfer the heat of the high temperature flue gas in the furnace body 1 to the heat-conducting oil in the preheating sleeve 3, thereby preheating the air in the air distribution chamber 2.

[0069] An independent control valve 16 is installed on the preheating conduit 5. This design allows the operator to precisely control the opening and closing of the preheating conduit 5 and adjust the heat transfer rate during the preheating process. By adjusting the independent control valve 16, it can be ensured that the heat transfer oil in the preheating jacket 3 operates within an appropriate temperature range, thereby avoiding overheating or underheating and further improving preheating efficiency and safety.

[0070] A PLC controller 17 is installed on the bottom side of the air distribution chamber 2. The PLC controller 17 is electrically connected to the independent control valve 16, the temperature sensor 12, and the pressure sensor 13. The PLC controller 17 can receive signals from the temperature sensor 12 and the pressure sensor 13 in real time, and accurately control the independent control valve 16 according to the preset program and algorithm. Through the intelligent adjustment of the PLC controller 17, the heat of the preheating conduit 5 can be accurately controlled, the air temperature in the air distribution chamber 2 can be monitored and adjusted in real time, and the pressure in the furnace body 1 can be stably controlled, thereby ensuring the stable operation and efficient combustion of the incinerator.

[0071] A pressure relief pipe assembly 15 is provided on the top side of the furnace body 1 and is connected to it. The pressure relief pipe assembly 15 is connected to the furnace body 1 by a quick-release clamp. This connection method is not only easy to install and disassemble, but also ensures that the pressure inside the furnace body 1 can be released quickly when needed, ensuring the safe operation of the incinerator. At the same time, the quick-release clamp connection also has good sealing performance, effectively preventing the leakage of flue gas inside the furnace body 1.

[0072] When the preheated air reaches the set temperature and the pressure is stable, the air enters the air distribution nozzle 8, which is connected to the air distribution chamber 2, through the mounting seat 7 at the connection between the air distribution chamber 2 and the furnace body 1. The nozzle tilt angle of the air distribution nozzle 8 is reasonably designed so that the air is sprayed into the furnace body 1 at a certain angle, thereby achieving uniform air distribution and efficient combustion.

[0073] During the incineration process, the flue gas generated inside the furnace body 1 is transferred to the heat transfer oil in the preheating jacket 3 through the preheating conduit 5 for heat recovery. At the same time, some of the flue gas is discharged from the furnace body 1 through the pressure relief pipe group 15 to maintain the pressure balance inside the furnace body 1. The use of ceramic fiber insulation pipes not only improves the preheating efficiency, but also effectively reduces heat loss, making the entire incineration process more energy-efficient and efficient.

[0074] The PLC controller 17 can precisely control the preheating conduit 5 through the independent control valve 16 according to the temperature changes and combustion requirements inside the furnace body 1, so as to realize the dynamic adjustment of heat. At the same time, the PLC controller 17 can also monitor the air temperature inside the air distribution chamber 2 and the pressure changes inside the furnace body 1 in real time, and perform alarms or automatic adjustments according to preset thresholds to ensure the safe operation and efficient combustion of the incinerator.
