Description

封闭式垃圾焚烧炉和焚烧炉体  Closed waste incinerator and incinerator body
技术领域 Technical field
本发明涉及垃圾焚烧炉技术领域, 特别涉及一种封闭式垃圾焚烧炉和焚烧炉体。 背景技术  The invention relates to the technical field of waste incinerators, in particular to a closed garbage incinerator and an incinerator body. Background technique
废弃垃圾包括: 城镇路面清扫垃圾、 居民生活垃圾、 餐饮垃圾、 医疗垃圾、 农产品加 工废弃物、 有机污泥、 粪便、 废旧塑料及轮胎等统称为废弃垃圾。 现有垃圾处理方式一般 采取填埋或填埋回收沼气发电和直接焚烧发电, 这些方法仅仅是利用了垃圾的少部分热 能, 但是在焚烧发电过程中总是有烟气排放, 造成二次污染问题仍然未能解决, 例如: 垃 圾填埋的渗透液污染和垃圾焚烧烟气排放的二次污染等。  Waste garbage includes: urban road cleaning garbage, household garbage, food waste, medical waste, agricultural product processing waste, organic sludge, manure, waste plastics and tires are collectively referred to as waste. Existing waste treatment methods generally use landfill or landfill to recover biogas power generation and direct incineration power generation. These methods only use a small part of the heat energy of the garbage, but there is always smoke emission during the incineration power generation, causing secondary pollution problems. Still unresolved, such as: permeate pollution from landfills and secondary pollution from waste incineration.
目前,用于废弃垃圾处理的焚烧炉主要有机械炉排炉、流化床焚烧炉、回转式焚烧炉、 静态热解焚烧炉等。 最为常用的机械炉排炉一般分为三个阶段, 即干燥段、 燃烧段和燃烬 段。 流化床主要由保持煤体流动的空气分散装置、 不燃物排出装置、 不燃物筛选煤体循环 装置等组成。 回转窖是在钢制的圆筒内部, 加装耐火衬里及有孔钢板焊接成筒状, 以垃圾 传送方向为轴心,呈小角度倾斜旋转的设备,其外围有两组环状钢制轮圈及几个滚轮支撑, 使圆筒缓慢的转动, 而将垃圾搅拌及向前输送。 这些炉的共同特征在于: (1 ) 、 燃烧温 度在 800-900°C范围内, 燃烧温度低, 燃烧效果差, 容易产生二恶英等有害气体; (2) 、 燃烧过程要向天空排放大量烟气(如氮氧化物、 二氧化碳、 二氧化硫及不完全燃烧的有害 气体二恶英等)造成二次污染; (3) 、 燃烧过程需要添加辅助燃料 (如煤、 油等) 造成燃 烧成本增高, 消耗大量的能源, 造成资源浪费; (4) 、 燃烧过程使用的助燃剂是空气, 由于空气中氮气是不参加燃烧反应而又要吸收大量的热量, 从而造成热损耗量大、 热效率 低。 由此可见, 这些炉存在如下不足之处: 炉体结构复杂、 炉膛容积大、 通入空气量大、 烟气排放量大、 燃烧温度低、 粉尘多、 热损耗量大, 既不节能也不环保。  At present, incinerators for waste disposal mainly include mechanical grate furnaces, fluidized bed incinerators, rotary incinerators, and static pyrolysis incinerators. The most commonly used mechanical grate furnaces are generally divided into three stages, namely the drying section, the combustion section and the burning section. The fluidized bed is mainly composed of an air dispersing device that keeps the coal body flowing, a non-combustible material discharging device, and a non-combustible material screening coal body circulating device. The slewing cymbal is a steel-made cylinder, which is equipped with a refractory lining and a perforated steel plate welded into a cylindrical shape, and is rotated at a small angle with the garbage conveying direction as the axis. There are two sets of ring-shaped steel wheels at the periphery. The ring and several roller supports, the cylinder rotates slowly, and the garbage is stirred and forwarded. The common characteristics of these furnaces are: (1), the combustion temperature is in the range of 800-900 °C, the combustion temperature is low, the combustion effect is poor, and harmful gases such as dioxins are easily generated; (2) The combustion process has to discharge a large amount into the sky. Flue gas (such as nitrogen oxides, carbon dioxide, sulfur dioxide and incompletely burned harmful gases such as dioxins) cause secondary pollution; (3) The combustion process requires the addition of auxiliary fuels (such as coal, oil, etc.), resulting in increased combustion costs. It consumes a lot of energy and wastes resources. (4) The combustion improver used in the combustion process is air. Because nitrogen in the air does not participate in the combustion reaction, it absorbs a large amount of heat, resulting in large heat loss and low thermal efficiency. It can be seen that these furnaces have the following deficiencies: The furnace structure is complex, the furnace volume is large, the amount of air introduced is large, the smoke emission is large, the combustion temperature is low, the dust is large, the heat loss is large, and neither energy saving nor energy is saved. Environmental protection.
在现有的垃圾焚烧炉中烟气污染物都是通过烟肉排放到大气层。由于烟气处理运行成 本高或处理系统维护困难等原因, 导致大量的烟气含有毒有害气体(如: 二氧化硫、 一氧 化碳、 氮氧化物、 二恶英等)及飞灰排放, 对环境空气、 水源和土壤造成严重污染, 这些 烟气长期排放会严重危及人类的生存环境。 现有的焚烧炉中对烟气二次污染问题仍未解 决。  In existing waste incinerators, smoke pollutants are emitted into the atmosphere through bacon. Due to high operating costs of flue gas treatment or difficult maintenance of the treatment system, a large amount of flue gas contains toxic and harmful gases (such as: sulfur dioxide, carbon monoxide, nitrogen oxides, dioxins, etc.) and fly ash emissions, to ambient air and water sources. And the soil causes serious pollution, and the long-term discharge of these flue gases will seriously endanger the living environment of human beings. The problem of secondary pollution of flue gas in existing incinerators remains unresolved.
现有的垃圾焚烧炉中由于有大量的烟气不断排放,垃圾焚烧的热量会随着烟气排放而 被带走一部分热量使炉温下降; 且由于垃圾含水分高而热值低, 难以燃烧, 干燥这些垃圾 需耗大量的热空气, 垃圾焚烧产生的热量因加热空气又被损耗一部分, 也造成炉温下降; 此外, 由于焚烧炉的炉膛体积大, 炉膛表面散热面积大、 散热速度快和散热量大, 垃圾焚 烧产生的热量随着炉膛表面不断散热而又被损耗一部分, 使炉温下降。 其结果是现有各种 垃圾焚烧炉热效率低, 不能达到节能降耗的效果。 In the existing garbage incinerator, due to the continuous discharge of a large amount of flue gas, the heat of waste incineration will be discharged along with the flue gas. A part of the heat is taken away to lower the temperature of the furnace; and because the water content of the garbage is high, the heat value is low, and it is difficult to burn. The drying of the garbage requires a large amount of hot air, and the heat generated by the waste incineration is lost due to the heating air, and the furnace is also caused. In addition, due to the large volume of the furnace of the incinerator, the heat dissipation area of the furnace surface is large, the heat dissipation speed is fast, and the heat dissipation amount is large. The heat generated by the waste incineration is partially lost due to the continuous heat dissipation of the surface of the furnace, and the furnace temperature is lowered. As a result, various garbage incinerators have low thermal efficiency and cannot achieve the effect of energy saving and consumption reduction.
在现有的焚烧炉中燃烧氧化反应的助燃剂都是采用空气中的氧, 由于垃圾的组成较为 复杂, 热值不稳定性导致炉温不稳定, 热值低时一般会添加柴油或煤等高热值燃料维持炉 温, 也就是说必须消耗部分能源才能够稳定焚烧炉的炉温。 在有氧化剂条件下, 垃圾中的 塑料燃烧不充分时, 容易导致二恶英等有毒有害气体的产生而造成严重的污染。 垃圾焚烧 通常需要加大空气量以增加湍流度, 让空气与垃圾在炉膛内形成沸腾状态, 这样会导致烟 气中飞灰量增加, 使烟气净化处理难度增高并造成处理成本增加。现有的垃圾焚烧炉中对 提高炉温、 减少能源使用量以及烟气和粉尘等污染物控制仍未得到有效的解决。 发明内容  The combustion improver in the existing incinerator uses oxygen in the air. Due to the complicated composition of the waste, the instability of the calorific value causes the furnace temperature to be unstable. When the calorific value is low, diesel or coal is generally added. The high calorific value fuel maintains the furnace temperature, which means that part of the energy must be consumed to stabilize the furnace temperature of the incinerator. In the case of oxidizing agents, when the plastic in the garbage is not sufficiently burned, it may cause serious pollution due to the generation of toxic and harmful gases such as dioxins. Waste incineration Generally, it is necessary to increase the amount of air to increase the turbulence, so that the air and the garbage form a boiling state in the furnace. This will increase the amount of fly ash in the flue gas, making the flue gas purification treatment more difficult and increasing the treatment cost. The existing waste incinerators have not been effectively solved for improving furnace temperature, reducing energy use, and controlling pollutants such as flue gas and dust. Summary of the invention
本发明的目的在于提供一种封闭式垃圾焚烧炉和焚烧炉体, 该炉结构简单、 炉膛体积 小、 燃烧速度快、 燃烧效果好、 燃烧过程产生的烟气量能大幅度减少, 并全部回收, 实现 零排放无污染。  The object of the present invention is to provide a closed type garbage incinerator and an incinerator body. The structure of the furnace is simple, the furnace volume is small, the burning speed is fast, the combustion effect is good, the amount of flue gas generated by the combustion process can be greatly reduced, and all the recycling is completed. , achieve zero emissions and no pollution.

与现有技术相比, 本发明具有如下显著效果:  Compared with the prior art, the present invention has the following remarkable effects:
( 1 ) 由于本发明的封闭式垃圾焚烧炉和焚烧炉体是将废弃垃圾压缩成原体积的 65 % -80 %的圆柱体压缩垃圾, 并放入圆柱形耐高温陶瓷滚筒内, 然后该滚筒首先进入温度为 200°C左右的下层焚烧炉 2-2的干燥区 16干燥, 压缩垃圾干燥后进入温度为 600°C左右的 热解区 17内热解, 然后再进入温度为 1200°C-1500°C的燃烧区 18内燃烧, 在燃烧区 18完 全燃烧后, 垃圾中碳及碳水化合物全部转化变成烟气, 烟气的成分主要是占 90 %的 C02、 占 10 %的 N02, 由于压缩垃圾是在缺氧状态下热解垃圾中的塑料袋等有机碳, 防止了二 恶英的生成。由于在圆柱形耐高温滚筒 3两侧喷入富氧气体,能使垃圾得到充分氧化燃烧, 变成烟气和灰渣。 可见本封闭式垃圾焚烧炉结构简单, 炉膛体积小, 燃烧速度快, 燃烧效 果好, 燃烧产生的烟气量大幅减少, 与现有相同垃圾处理量的垃圾焚烧炉相比, 其炉膛体 积可缩小 2 / 3, 焚烧过程产生的烟气量减少 3 / 4。 (1) Since the closed type garbage incinerator and the incinerator body of the present invention compresses the waste garbage into 65%-80% of the cylindrical compressed garbage of the original volume, and puts it into a cylindrical high-temperature ceramic drum, and then the drum First, the drying zone 16 of the lower incinerator 2-2 having a temperature of about 200 ° C is dried, and the compressed garbage is dried and then enters a temperature of about 600 ° C. The pyrolysis zone 17 is pyrolyzed and then burned into the combustion zone 18 at a temperature of 1200 ° C - 1500 ° C. After the combustion zone 18 is completely burned, the carbon and carbohydrates in the waste are all converted into flue gas, flue gas. The composition is mainly 90% of C0 2 and 10% of N0 2 . Since compressed garbage is an organic carbon such as a plastic bag that is pyrolyzed in an anoxic state, the formation of dioxins is prevented. Since the oxygen-rich gas is injected on both sides of the cylindrical high-temperature resistant drum 3, the garbage can be sufficiently oxidized and burned to become flue gas and ash. It can be seen that the closed garbage incinerator has a simple structure, a small furnace volume, a fast burning speed, a good combustion effect, and a large reduction in the amount of flue gas generated by combustion, and the furnace volume can be reduced compared with the existing waste incinerator of the same garbage disposal amount. 2 / 3, the amount of smoke generated by the incineration process is reduced by 3 / 4.

本封闭式垃圾焚烧炉的运行过程是这样的:  The operation process of the closed garbage incinerator is as follows:
垃圾从封闭式垃圾储存罐 8进入挤压式推进器 1的内腔,经挤压式推进器挤压成体积 仅为原体积 65 %-80 %的压缩垃圾 14,进而被推入上层焚烧炉体 2-1的装料区 21的圆柱形 耐高温滚筒 3的第 2段 3-2内, 圆柱形耐高温滚筒 3依靠自重在有坡度 5-10度的上导轨 6 上向下滚动移动, 圆柱形耐高温滚筒 3装载着压缩垃圾 14进入下层焚烧炉体 2-2的干燥 区 16, 由于下导轨 15有坡度 3-8度, 所以圆柱形耐高温滚筒 3从干燥区 16 (温度为 200 °C )干燥后滚动移动进入热解区 17 (温度为 600°C )热解, 再继续进入燃烧区 18 (温度为 1200°C ) , 此时位于圆柱形耐高温滚筒 3两侧的第一喷咀 4和第二喷咀 12同时向圆柱形 耐高温滚筒 3内的压缩垃圾 14喷射富氧气体,启动喷枪点燃压缩垃圾 14并使其在高温富 氧状态下完全燃烧。 圆柱形耐高温滚筒 3的步进式移动与燃烧区 18压缩垃圾的焚烧速度 匹配, 每焚烧完毕一个圆柱形耐高温滚筒 3内的压缩垃圾 14后, 升降器 22就将焚烧完毕 的圆柱形耐高温滚筒 3从下层焚烧炉体 2-2燃烧区 18升至上层焚烧炉体 2-1的待吸灰区 19, 圆柱形耐高温滚筒 3沿着上导轨 6移动到吸灰区 20时, 程序控制器启动吸灰器 5动 作, 将该圆柱形耐高温滚筒 3内的灰渣吸出, 然后, 空的圆柱形耐高温滚筒 3沿着上导轨 6向装料区 21移动, 假设每焚烧完毕一个圆柱形耐高温滚筒 3内的压缩垃圾 14的时间控 制为 1分钟 (具体时间与压缩垃圾大小有关) , 所以升降器 22的升降时间亦控制为 1分 钟, 也就是说圆柱形耐高温滚筒 3每 1分钟向前移动一个筒位, 焚烧炉内的圆柱形耐高温 滚筒 3沿着上导轨 6依次从上层焚烧炉体 2-1的装料区 21滚动移动至下层焚烧炉 2-2的干 燥区 16、热解区 17, 再进入燃烧区 18, 此时第一喷咀 4与第二喷咀 12同时向进入燃烧区 18的圆柱形耐高温滚筒 3内的压缩垃圾 14喷射富氧气体,点燃压缩垃圾 14并使其完全燃 烧, 产生温度达 1200°C的烟气。  The garbage enters the inner cavity of the squeeze propeller 1 from the closed garbage storage tank 8, and is extruded into a compressed garbage 14 having a volume of only 65%-80% of the original volume by the squeeze propeller, and then pushed into the upper incinerator.

The time of the compressed garbage 14 in the cylindrical high temperature resistant drum 3 is controlled to be 1 minute (the specific time is related to the size of the compressed garbage), so the lifting time of the lifter 22 is also controlled to 1 minute, that is, the cylindrical high temperature resistant drum 3 is 1 minute forward to move a cylinder position, the cylindrical high temperature resistant drum 3 in the incinerator is sequentially moved along the upper rail 6 from the charging zone 21 of the upper incinerator body 2-1 to the lower incinerator 2-2. The drying zone 16, the pyrolysis zone 17, and the combustion zone 18, at which time the first nozzle 4 and the second nozzle 12 simultaneously simultaneously eject oxygen-enriched gas into the compressed waste 14 entering the cylindrical high temperature resistant drum 3 of the combustion zone 18.
