垃圾焚烧是实现垃圾减量化、 无害化和资源化处理的主要途径之一。 目前垃圾焚烧已逐渐成为城市生活垃圾处理的主要途径, 垃圾经过现代化 的焚烧处理,体积一般可减少 80°/»-90°/», 同时可以消灭各种病原体, 将有害 物质转化为无害物, 还可以实现资源化的利用。  Waste incineration is one of the main ways to achieve waste reduction, harmless and resource treatment. At present, waste incineration has gradually become the main way to treat municipal solid waste. After modern incineration, the waste can be reduced by 80°/»-90°/», and various pathogens can be eliminated to convert harmful substances into harmless substances. , can also achieve the use of resources.
现有的垃圾焚烧多釆用具有焚烧炉排的机械式垃圾焚烧炉, 所述炉排 主要包括: 顺推往复炉排、 逆推往复炉排、 滚筒式炉排等。 图 1所示的垃 圾焚烧炉就为釆用顺推往复炉排的一种垃圾焚烧炉。 如图 1所示, 所述垃 圾焚烧炉包括进料口 1、给料炉排 2、位于炉膛内的用于垃圾焚烧的炉排 3、 位于焚烧炉排下部的一次风供风系统 4、 位于炉喉部的二次风供风系统 5 以及排渣口 6。焚烧炉排整体构成用于焚烧垃圾的炉床,所述炉床沿纵向分 为干燥段、 燃烧段和燃尽段, 焚烧炉排整体沿纵向分为 3 个焚烧单元, 每 一焚烧单元由多个滑动炉排片、 翻动炉排片和固定炉排片组成。 垃圾从进 料口倒入所述垃圾焚烧炉, 通过给料炉排的往复推动作用所述垃圾进入所 述焚烧炉内的炉床上进行焚烧, 在所述干燥段所述垃圾被烘干、 脱水, 所 述垃圾主要在所述燃烧段进行燃烧, 经过燃尽段的垃圾已经燃烧殆尽, 之 后剩余的炉渣进入排渣口, 由排渣口排出炉外。 其中所述一次风从所述焚 烧炉排底部的风室送入, 用于燃烧所述垃圾, 所述二次风从所述垃圾焚烧 炉的炉喉部送入, 用于将燃烧后烟气中的可燃气体燃尽。 垃圾中燃烧的可 燃物质释放热量与原垃圾中的可燃物质的热量的比值, 即垃圾燃尽率是垃 圾焚烧工艺中一个非常重要的参数指标。  The existing garbage incineration uses a mechanical waste incinerator having an incinerator, and the grate mainly comprises: a reciprocating grate, a reverse reciprocating grate, a drum grate, and the like. The waste incinerator shown in Figure 1 is a waste incinerator that uses a reciprocating grate. As shown in FIG. 1, the garbage incinerator comprises a feed port 1, a feed grate 2, a grate 3 for waste incineration located in the grate, and a primary air supply system 4 located in the lower part of the incinerator. The secondary air supply system 5 of the furnace throat and the slag discharge port 6. The incinerator grate integrally constitutes a hearth for incinerating garbage, and the grate is divided into a drying section, a burning section and a burning section in the longitudinal direction, and the incinerator grate is divided into three incineration units as a whole in the longitudinal direction, and each incineration unit is composed of a plurality of incineration units. The sliding grate piece, the rotating grate piece and the fixed grate piece are composed. The garbage is poured into the garbage incinerator from the feed port, and the garbage is incinerated into the hearth of the incinerator by the reciprocating push of the feed grate, and the garbage is dried and dehydrated in the drying section. The garbage is mainly burned in the combustion section, and the garbage passing through the burnout section has been burned out, and then the remaining slag enters the slag discharge port and is discharged from the slag discharge port. Wherein the primary air is sent from a plenum at the bottom of the incinerator for burning the waste, and the secondary air is fed from the throat of the waste incinerator for use in the post-combustion flue gas The combustible gas in the burnout. The ratio of the amount of heat released by the combustible material burned in the waste to the heat of the combustible material in the original waste, that is, the burnout rate of the waste is a very important parameter in the waste incineration process.
上述垃圾焚烧炉在实际应用中有以下缺陷:  The above waste incinerator has the following defects in practical applications:
1 ) 由于上述炉排整体上为纵向布置, 在宽度方向由 4列炉排单元并列 组成, 所述炉排横向分四段驱动, 每个单元由一组油缸控制, 这就造成在 上述炉排中间部位留有液压驱动装置的空间, 而炉排本身结构比较紧凑, 这个中间的空间较小, 造成了这个部位由炉膛内传递出的热量积聚, 温度 升高,根据运行经验, 基本上该处温度在 以上, 而现有焚烧炉排液压 驱动装置的油管多釆用管接头连接结构, 在炉排中部两段驱动轴相接处的 过高温度会导致上述焚烧炉排油缸密封圈老化, 经常性漏油, 甚至由此引 起火灾, 运行上困难较大。 1) Since the above-mentioned grate is arranged in a longitudinal direction as a whole, it is composed of four rows of grate units juxtaposed in the width direction, and the grate is driven in four stages in a lateral direction, and each unit is controlled by a group of oil cylinders, which is caused in the above grate The middle part has space for the hydraulic drive, and the grate itself is compact. The space in the middle is small, which causes the heat generated in the furnace to accumulate and the temperature rises. According to the operating experience, basically the temperature is above, and the oil pipe of the existing incinerator hydraulic drive unit is used more. The pipe joint connection structure, the excessive temperature at the junction of the two drive shafts in the middle of the grate will cause the above-mentioned incinerator exhaust cylinder seal ring to age, frequent oil leakage, and even cause fire, which is difficult to operate.
2 )现有技术中生活垃圾焚烧炉给料炉排的给料小车在向前推料过程中 经常出现小车尾部翘起过大造成小车卡死不能正常推料及回退, 需要人工 手拉葫芦将小车拉回初始位置, 给生产运行带来很多困难。 同时由于现有 技术中给料炉排和焚烧炉排的宽度不同, 导致生活垃圾在炉排横向上分布 不均匀, 直接影响了垃圾的燃烧效果。  2) In the prior art, the feeding trolley of the feeding waste incinerator of the domestic garbage incinerator often appears in the process of pushing forward the trolley, and the tail of the trolley is too large to cause the trolley to be stuck and cannot be pushed and retracted normally, and the manual chain hoist is required. Pulling the car back to the initial position brings many difficulties to the production operation. At the same time, due to the different widths of the feed grate and the incinerator row in the prior art, the distribution of domestic garbage in the lateral direction of the grate is uneven, which directly affects the burning effect of the garbage.
3 ) 现有的末段垃圾焚烧炉排单元过短, 难以满足在我国生活垃圾高水 分条件下尽可能将垃圾燃尽的要求。  3) The existing end-of-life waste incinerator unit is too short to meet the requirements of burning up the garbage as much as possible under the high water conditions of domestic garbage.
4) 炉排一次风的冷却效果较差, 炉排之间的摩擦较大, 造成炉排片磨 损严重, 影响了寿命, 但上述炉排的更换成本却非常高。  4) The cooling effect of the grate primary wind is poor, the friction between the grate is large, causing serious damage to the grate piece and affecting the life, but the replacement cost of the above grate is very high.
5 )现有垃圾焚烧炉的翻动炉排经常出现轴向窜动,由此造成拉杆断裂, 翻动炉排片与侧墙炉排片间磨损严重, 严重影响生产运行。  5) The flipping grate of the existing garbage incinerator often has axial turbulence, which causes the tie rod to break, and the wear between the tumbling furnace row and the side wall grate plate is serious, which seriously affects the production operation.
6 ) 由于中国目前的垃圾分类工作还没有像西方发达国家做的那样好, 因此目前中国的城市生活垃圾中厨余物比较多, 含水量也比较高、 热值较 低。 加上现有的供风系统和炉排的动作多是根据运行人员的经验进行的手 动调节, 受主观因素和运行人员的经验影向较大且不能及时的根据垃圾热 值的变化而进行调整, 导致垃圾的燃烧效果较差, 出生渣率偏高。  6) Since China's current garbage sorting work has not been as good as that of developed countries in the West, China's urban domestic waste currently has more kitchen waste, higher water content and lower calorific value. In addition, the existing air supply system and the operation of the grate are mostly manually adjusted according to the experience of the operating personnel. The subjective factors and the experience of the operating personnel are large and cannot be adjusted according to the change of the calorific value of the garbage. , resulting in poor combustion of garbage, high birth slag rate.
7 ) 翻动炉排片翻起 25度后, 回落时无缓冲, 对支撑轮的冲击较大。 7) After the tumbling furnace is turned up 25 degrees, there is no cushion when falling back, and the impact on the support wheel is large.
8 ) 焚烧炉排一次风入炉温度设计为 180 C , 根据已运行垃圾电厂的运 行经验, 垃圾的水分偏高, 尤其是在冬季, 一次风的入炉温度偏低不利于 垃圾的干燥和烧透。 8) The temperature of the incinerator grate is designed to be 180 C. According to the operating experience of the waste power plant that has been operated, the moisture of the garbage is high, especially in winter. The low temperature of the primary air is not conducive to the drying and burning of the garbage. through.
9 ) 给料炉排及滑动炉排的速度、 行程和频率是通过料层压差来控制, 由于垃圾成分、 热值等都有较大波动, 因而该控制方法不利于垃圾燃尽。  9) The speed, stroke and frequency of the feed grate and the sliding grate are controlled by the difference in material lamination. Because of the large fluctuations in the composition of the garbage and the calorific value, the control method is not conducive to the burning of the garbage.
因此, 急需一种新型的垃圾焚烧炉及其控制方法, 以解决现有垃圾焚 烧炉中存在的各种不足。 发明内容  Therefore, there is an urgent need for a new type of waste incinerator and its control method to solve various deficiencies in existing garbage incinerators. Summary of the invention

本发明解决了上述炉排垃圾焚烧炉存在的技术问题, 提供一种更适合 中国生活垃圾特点的焚烧炉排炉,并釆用更为合理的供风和炉排控制方案, 使得釆用本炉排炉及控制方案的垃圾焚烧发电厂高效、 稳定的运行。 本发 明具有以下优点:  The invention solves the technical problems existing in the above-mentioned grate waste incinerator, provides an incinerator grate furnace which is more suitable for the characteristics of domestic domestic garbage, and adopts a more reasonable supply air and grate control scheme, so that the furnace is used Efficient and stable operation of waste incineration power plants with furnaces and control schemes. The present invention has the following advantages:
1、 因为炉排整体沿纵向 (生活垃圾的在焚烧炉内的前进方向)分为五个单 元, 为垃圾的干燥、 燃烧和燃尽提供了足够的空间和时间, 能够显著改善垃 圾的燃烧状况, 提高垃圾的燃尽率; 每排炉排片横向由一根轴进行驱动并且 在两侧和中间位置进行至少三点支撑可以控制液压系统潜在漏油点和驱动 轴、 炉排的变形, 从而使运行更为稳定、 可靠同时改善燃烧效果; 驱动炉排 片的液压油管路釆用焊接油管路, 这样的设计可以避免由于温度过高, 焚烧 炉排油缸密封圈老化, 经常性漏油, 由此引起火灾的可能性, 由于炉排整体 为模块化结构, 安装速度快、 精度高。 2、 由于限位支撑轮与盖板之间留合理的间隙, 这样给料炉排在前进过程 中, 向上方向的位移被滚轮限制在很小的范围内, 有效保证了给料炉排按设 计的运行轨道平稳运行, 不会发生偏移及卡死的现象, 有效解决了给料小车 经常脱轨的问题。 同时, 给料炉排与焚烧炉排的宽度相同, 使得焚烧炉排横 向上垃圾分布更为均匀, 燃烧更充分。 1. Because the grate is divided into five units along the longitudinal direction (the direction of the domestic garbage in the incinerator), it provides sufficient space and time for the drying, burning and burning of the garbage, which can significantly improve the burning status of the garbage. , to improve the burnout rate of garbage; each row of furnace rows is driven by one shaft in the lateral direction and at least three points of support on both sides and intermediate positions can control the potential oil leakage point of the hydraulic system and the deformation of the drive shaft and the grate, thereby The operation is more stable and reliable, and the combustion effect is improved. The hydraulic oil pipeline for driving the grate plate is welded with the welding oil pipe. This design can avoid the aging of the exhaust cylinder of the incinerator due to excessive temperature, and frequent oil leakage. The possibility of fire, due to the modular structure of the grate as a whole, the installation speed is fast and the precision is high. 2. Due to the reasonable gap between the limiting support wheel and the cover plate, the feeding furnace row is in the forward process, and the upward displacement is limited by the roller to a small range, which effectively ensures the design of the feeding furnace row. The running track runs smoothly, and there is no phenomenon of offset and jamming, which effectively solves the problem that the feeding trolley often derails. At the same time, the width of the feed grate and the incinerator grate are the same, so that the garbage distribution in the lateral direction of the incinerator is more uniform and the combustion is more complete.
3、 由于末端垃圾炉排的加长, 垃圾在焚烧炉内的停留时间延长, 从而提 高了生活垃圾的燃尽率。  3. Due to the lengthening of the end garbage grate, the residence time of the garbage in the incinerator is prolonged, thereby increasing the burnout rate of domestic garbage.
4、 因为将翻动炉排片分成两部分 (上盖板和翻动炉排片支撑) , 在实际 使用中, 即使磨损了上盖板, 可以直接将上盖板进行更换, 而无须更换翻动 炉排支撑, 避免了现有技术中需要整个炉排片进行更换的缺陷, 节约了成本、 减少了材料损耗, 降低了运行成本; 由于翻动滚轮由两个或两个以上的支撑 件支撑, 整个翻动滚轮中间支撑由一点变成了两点以上, 有效的分解了托轮 的受力, 保证托轮中的轴承在长期运行中不会损坏, 并有效限制了转动大轴 的挠度, 延长了转动大轴的使用寿命。 该托轮釆用耐高温的滚子轴承, 即满 足焚烧炉内高温的使用环境又满足了焚烧炉的高负荷运行, 且该轴承又具有 自动对中调心的功能, 非常适合该焚烧炉内的使用工况; 由于在翻动炉排片 翻起后由 25度回落至 21度后, 通过液压油进行缓冲, 减小了对支撑轮的冲 击, 延长了支撑轮的寿命; 由于滑动炉排片、 固定炉排片和翻动炉排片均设 置了挡灰板, 可以最大可能的减少炉排的漏灰; 由于设置了弹性耐磨刮片, 所以在相临两排炉片之间几乎没有摩擦, 提高了使用寿命; 炉排组件为模块 化结构, 安装精度高, 安装速度快, 成本更低。  4. Because the flipper row is divided into two parts (upper cover and flipper support), in actual use, even if the upper cover is worn out, the upper cover can be directly replaced without replacing the flipper support. It avoids the defects in the prior art that the entire grate piece needs to be replaced, saves cost, reduces material loss, and reduces running cost; since the turning roller is supported by two or more supporting members, the entire supporting roller intermediate support is The point becomes more than two points, effectively decomposing the force of the supporting wheel, ensuring that the bearing in the supporting wheel will not be damaged during long-term operation, and effectively limiting the deflection of the rotating large shaft and prolonging the service life of the rotating large shaft. . The roller rim uses a high temperature resistant roller bearing, that is, it satisfies the high temperature environment in the incinerator and satisfies the high load operation of the incinerator, and the bearing has the function of automatic centering and aligning, which is very suitable for the incinerator. The working condition; due to the backlash from 25 degrees to 21 degrees after the turning of the turning furnace, the buffer is relieved by the hydraulic oil, which reduces the impact on the supporting wheel and prolongs the life of the supporting wheel; Both the grate piece and the tumbling furnace row plate are provided with ash shims, which can reduce the ash leakage of the grate as much as possible. Because of the elastic wear-resistant squeegee, there is almost no friction between the two rows of slabs, which improves the use. Life; grate assembly is modular, with high installation accuracy, fast installation and lower cost.
5、 因为燃烧室出口烟气温度反应了炉排上垃圾的燃烧状况,如果烟气温 度较高说明炉排上面的垃圾燃烧状况较好, 否则燃烧状况不佳, 因此根据燃 烧室出口烟气温度对一次风进行调整能够改善炉排上垃圾的燃烧状况。 根据 炉膛出口烟气含量和氧含量对二次风进行调整能够显著改善挥发分的燃烧状 况, 减小 C O等污染物的排放。 在垃圾焚烧炉一次风供应系统设计中, 将一次 风的入炉温度提高到 220 C , 能够使垃圾燃烧得更充分, 燃尽率更高。  5. Because the flue gas temperature at the exit of the combustion chamber reflects the burning condition of the garbage on the grate, if the temperature of the flue gas is higher, the burning of the garbage above the grate is better, otherwise the combustion condition is not good, so according to the flue gas temperature at the exit of the combustion chamber Adjusting the primary air can improve the burning of the garbage on the grate. Adjusting the secondary air according to the flue gas content and oxygen content of the furnace outlet can significantly improve the combustion of volatiles and reduce the emission of pollutants such as C O. In the design of the primary air supply system of the waste incinerator, the temperature of the primary air is increased to 220 C, which can make the garbage burn more fully and burn out more.
6、 因为火床长度和高度反应了垃圾焚烧炉内生活垃圾的燃烧状况, 因此 根据火床长度和高度对炉排进行控制能使焚烧炉的垃圾始终处于很好的燃烧 状况; 此外炉排片的温度也反应了垃圾焚烧炉内垃圾的燃烧状况, 因此根据 炉排片的温度对给料炉排、 滑动炉排和翻动炉排进行调整, 也能够使炉内的 生活垃圾始终处于很好的燃烧状况。 附图说明 6. Because the length and height of the fire bed reflect the burning condition of the domestic garbage in the garbage incinerator, the control of the grate according to the length and height of the fire bed can keep the garbage of the incinerator in a good burning condition; The temperature also reflects the burning condition of the garbage in the waste incinerator. Therefore, adjusting the feeding grate, the sliding grate and the turning grate according to the temperature of the grate piece can also make the domestic garbage in the furnace always in a good burning condition. .
