一种燃烧供热*** 技术领域
本发明涉及一种燃烧供热***， 具体涉及一种节能环保型燃烧供热***。 背景技术
在陶瓷、化工、食品等行业使用的燃烧供热***， 普遍采用天燃气、柴油、 重油、 煤等作为燃料， 通过各式燃烧炉 （发生炉） 产生高温气体， 以供干燥、 烧结工艺使用。 专利 1216814A、 2540597Y. 201129853Y 2191971Y等对其实 施结果进行了具体描述。
随着社会的发展、 能源的紧缺以及国家环保政策的限制， 现有各式燃烧供 热***也逐渐遇到了很多突出的问题。 如柴油、 重油、 天燃气等燃料， 上世纪 九十年代普遍用于建筑陶瓷、 化工等行业加热、 干燥工艺， 具有热效率高， 易 于实现自动化等优点， 但是由于油价的不断上涨， 使得燃料成本逐渐超出了企 业能够承受的范围， 目前仅有食品、 特种陶瓷等对能源清洁度要求苛刻的行业 继续使用天燃气等作为燃料。
以煤炭为燃料的供热***种类繁多， 是建陶、 化工等行业主要采用的供热 方式。 目前工业化应用的有水煤浆方式、 链排炉方式、 干煤粉方式以及煤气方 式等， 但在实际使用过程中， 各种方式均存在燃料利用效率与热气体清洁度之 间的矛盾， 如水煤浆、 链排炉、 干煤粉等方式， 以燃料直接燃烧的方式提供热 量， 能源利用效率高， 但煤的直接燃烧带来大量的粉尘、 颗粒等， 严重影响了 热源的品质。 而现在普遍采用的旋风除尘根本无法达到企业的要求。 煤气方式 采用煤气发生炉将煤气化后除尘， 提高了热源的清洁度， 但是煤气化过程本身 就有一定的转化率， 加之有时需要将热煤气冷却后使用， 大幅降低了能源的利 用效率。

燃烧炉 2主要结构由燃烧炉主体部分及热风管道、 点火***、 电器控制、 测温仪表***等辅助设备组成。 启动时用燃油将燃烧室升温至 800°C， 由喷枪 雾化切向喷入炉膛， 着火旋转燃烧， 在离心力作用下， 灰尘附集于炉膛内壁， 螺旋下降至出渣口进入水封池内， 燃烧室中心的热空气上升至上部射流旋风除 尘器 3， 在空气角向喷射作用下， 热烟气高速旋转， 较细的灰尘沿旋风除尘器 3壁螺旋滑至导灰口， 中心洁净的热烟气通过供热风管直接导出。
陶瓷膜高温除尘器 4为一种以高温陶瓷膜滤芯为核心， 集高温烟尘净化、 脉冲反吹、 自动清灰与控制为一体的高效、 节能高温气体净化装置。 其中， 高 温陶瓷膜滤芯优先选用堇青石、 碳化硅或者陶瓷纤维材质， 本实施例中选用堇 青石高温陶瓷膜材料。 陶瓷膜高温除尘器的具体结构如图 2所示， 包括除尘器外壳 7、管板 11和 多孔陶瓷膜滤芯 12， 除尘器外壳 7下部设有含尘高温气体入口 13， 顶部设有 清洁气体出口 8， 除尘器内安装管板 11， 管板 11上悬吊安装数支多孔陶瓷膜 滤芯 12, 除尘器由管板 12分隔成下部含尘气体腔 15和上部清洁气体腔 16， 管板 11上方设有喷吹清灰***， 喷吹清灰***包括文丘里喷射器 10、 气体管 路 9和清灰口 14， 气体管路 9贯穿陶瓷膜高温除尘器的上部清洁气体腔 16， 气体管路 9上安装与多孔陶瓷膜滤芯位置对应的文丘里喷射器 10，除尘器外壳 7的底部设有清灰口 14。
从燃烧***出来的含尘高温气体进入管板 11下方的下部含尘气体腔 15， 经过多孔陶瓷膜滤芯 12除尘后的清洁气体进入管板 11上方的上部清洁气体腔 16, 这样， 粉尘颗粒被截留在多孔陶瓷膜滤芯 12 的外表面， 长时间使用后， 多孔陶瓷膜滤芯 12外表面上的粉尘颗粒会不断堆积成粉尘滤饼， 造成气体的 流动阻力增大， 一旦达到设定的压降或是经过一定的预设过滤时间， 就开始清 除粉尘滤饼。 反吹方式采用分组脉冲反吹， 这种反吹方式， 可以有效的利用容 器内的气体， 少量的气体就可以完成反吹再生。 每支多孔陶瓷膜滤芯 12上方 设置有文丘里喷射器 10， 每个文丘里喷射器像泵一样工作， 并为多孔陶瓷膜滤 芯 12 的清洁吸入额外的清洁气体， 反向喷射的部分动能转化为压能。 这样， 在多孔陶瓷膜滤芯 12 的空腔内产生压力反向于过滤气体流动的方向， 从而进 行在线反吹， 克服过滤方向上的压降和粉尘滤饼的黏着强度。 文丘里喷射器使 得有一个均匀流动气体分布穿过， 并沿过滤元件有一个均匀的延伸， 通过对热 应力的有利的热活塞流使得热冲击最小化。 该高温陶瓷膜过滤器最高使用温度 可达 750°C， 净化效率达到 99.9%， 出***尘浓度可控制在 5毫克每立方米以 内。 本发明的工作原理及过程为： 其利用农业副产品 （如棕榈壳、 椰壳）、 煤 炭等作为燃料， 先由粉碎机将燃料磨至 l〜2mm， 然后送入磨粉机进行细磨， 磨至 300目左右喷入燃烧炉进行燃烧。燃烧炉 2可产生 1200Ό左右的高温烟气， 该高温烟气经二次配风后降至 650°C左右，先通过旋风除尘器 3除去粗颗粒后， 经高温风机 5负压引入陶瓷膜高温除尘器 4过滤去除烟气中的微细粉尘， 清洁 的热源进入喷雾干燥塔 6用于物料的干燥。
控制***核心控制进入喷雾干燥塔 6前热风温度和压力， 温度通过燃烧炉 2进行控制，压力通过高温风机 5进行控制。控制***全部采用 PLC进行控制， ***选用模块式的组合结构， 并与工业计算机组成集中控制***， 界面友好， 操作方便， 可以满足用户的特定要求。
本发明开发的燃烧供热净化***， 利用煤炭为燃料， 可大大降低喷雾干燥 塔 6的燃料费用， 以 10000型喷雾干燥塔为例， 设备投资在 600-800万左右， 相对于天然气燃料炉， 一台 10000型喷雾干燥塔每年综合能耗节约 300万元以 上； 相对于水煤浆燃烧炉每年可节省燃料费用 200万元左右。
