Description

除尘箱及具有该除尘箱的除尘系统
技术领域
本发明关于一种除尘系统， 且特别是关于一种对含尘气流进行过滤的 除尘箱及具有该除尘箱的除尘系统。 背景技术
目前， 国内干式除尘扫路车普遍使用除尘箱对含尘气流进行过滤除尘， 虽有部分厂家采用布袋或板式滤网作为过滤体， 但在使用中存在清灰效率 低、 易糊袋等缺陷， 所以， 采用布袋或板式滤网作为干式除尘的产品越来 越少， 更多的干式除尘扫路车采用了除尘箱除尘的模式。
现有的除尘箱， 不论是采用内设三个滤气筒的还是内设四个滤气筒的， 除尘箱分为上下两部分， 箱体上部设有高压去尘器， 还有直通大气的排气 口， 箱体下部设有通入含尘气流的进气口及过滤后的粉尘收集装置， 滤气 筒位于排气口与进气口之间。 除尘箱制作上多采用薄板， 箱体内部呈简单 的矩形， 部分箱体内设骨架进行加强； 箱体内滤气筒对称布置。
箱体上下部分基本隔绝， 但含尘气流从除尘箱下部下方进入， 经过滤 气筒过滤后， 干净空气可进入箱体上部最终排入大气。 通过程序控制， 高 压去尘器能定期释放出高压空气对滤气筒进行吹喷， 以清除吸附在滤气筒 外表面的粉尘； 被清除的粉尘在自身重量作用下落入箱体下部的集灰斗， 并最终通过吸嘴被送入垃圾箱， 这是下进上排的进气除尘模式。 但是， 这 种下进上排的进气除尘方式存在不足之处， 源源不断的含尘气流从除尘箱 下方涌入并充斥箱体内部， 当滤气筒壁上的粉尘被箱体上方的脉冲清灰装 置清除， 受箱体下部高速涌入的含尘气流的影响， 被清除的粉尘无法顺利 地落入箱体下部的集灰斗。 含尘气流虽然不断地被滤气筒过滤， 粉尘留在 滤气筒外壁上， 最后又被脉冲清灰装置从滤气筒壁上清除下来， 但其中大 部分粉尘又不断地被重新搅入含尘气流中， 使得滤气筒上部的含尘气流中 的粉尘浓度始终保持在一个较高的状态， 滤气筒的过滤除尘效率并不理想， 降低了干式过滤除尘的效率。 发明内容

请参照图 1，本发明除尘系统 1可以应用于干式除尘扫路车或对含尘气 流进行过滤除尘的除尘器。除尘系统 1包括除尘箱 100和吸嘴 200。除尘箱 100过滤下来的粉尘通过吸嘴 200排到垃圾箱。
除尘箱 100包括箱体 10、 高压去尘器 20和滤气筒 30。 箱体 10内设隔 板 17将箱体 10分隔成箱体上部 12和箱体下部 13。 箱体上部 12开设排气 口 15， 高压去尘器 20装设在箱体上部 12。 滤气筒 30可以可分离地安装在 隔板 17上， 或通过固定装置 （图未示） 安装在箱体下部 13。 滤气筒 30包 括由滤网卷成的网筒 31，网筒 31的一端并未封闭，为滤气筒 30的顶部 32; 另一端封闭， 为滤气筒 30的底部 33。 隔板 17上开设与滤气筒 30的顶部 32对应的通孔 （图未示）， 从而滤气筒 30的顶部 32与排气口 15相通。 箱 体下部 13的上端， 靠近滤气筒 30的顶部 32处开设进气口 16。含尘气流从 进气口 16进入箱体 10， 然后经过滤气筒 30的过滤， 最后通过排气口 15排 出。 箱体 10的底端， 靠近滤气筒 30的底部 33设计成或连接有锥形的集灰 斗 14， 以方便收集过滤后的粉尘， 集灰斗 14的口径从上至下逐渐缩小。 滤 后的粉尘掉落到落入集灰斗 14， 然后通过吸嘴 200排到垃圾箱。
图 1中， 箭头 A为含尘气流的流动方向， 箭头 B为经滤气筒 30过滤 的干净气体的流动方向，箭头 C为高压去尘器 20释放出的高压气体的流动 方向， 箭头 D为过滤出来的灰尘落下的方向。 在本实施例中， 含尘气流从 箱体下部 13上方进入， 经过滤气筒 30过滤后， 干净空气可进入箱体上部 12并最终排入大气。通过程序控制， 高压去尘器 20能定期释放出高压空气 对滤气筒 30进行吹喷， 以清除吸附在滤气筒 30外表面的粉尘。 被清除的 粉尘在自身重量和含尘气流的作用下落入箱体下部 13的集灰斗 14，并最终 通过吸嘴 200被送入垃圾箱。
请同时参照图 2， 在本实施例中， 箱体下部 13内设四个对称排列的滤 气筒 30， 箱体下部 13整体呈矩形， 箱体下部 13具有四个侧面板 131， 四 个侧面板 131采用斜边 134连接。进气口 16设在其中一个侧面板 131的中 部。在进气口 16处设置二直导流板 132， 二直导流板 132向进气口 16的中 心处延伸， 成八字形。 其它三个侧面板 131的内侧中部设有 V形凸起 133。 箱体下部 13的内部空间的中部设有二个弧形导流板 136a，所述二个弧形导 流板 136a分别对应朝向靠近进气口 16处的二个滤气筒 30。导流板 136a的 长度与滤气筒 30的长度可以相同也可以不同， 主要看设计需要。 直导流板 132、 V形凸起 133和弧形导流板 136a组成导流组合的第一种结构， 使进 入箱体下部 13的含尘气流环绕滤气筒 30流动。
优选地， 箱体 10采用折弯板， 这样可以使用较薄的板材制作箱体 10 面板， 无需设置内框架及加强梁， 更节省材料。 同时， 由于箱体 10焊接量 大大减少， 箱体 10制作中的变形更小， 箱体 10的平整度更易得到保证。 但是， 箱体 10也可以不采用折弯板制作箱体 10的面板， 而使用非折弯板 加成型板的方式制作， 在现有的折弯处采用相近的成型零件 （支板或圆弧 板） 与箱体 10内板拼接。
图 3显示了导流组合的第二种结构， 在导流组合第一种结构的基础上， 取消正对含尘气流进口的侧面板 131 的内侧中部的凸起 133， 使与进气口 16正对的侧面板 131的内侧为平整表面。
图 4显示了导流组合的第三种结构， 在导流组合第一种结构的基础上， 将二个弧形导流板 136a延伸至与位于所述进气口 16二侧的所述侧面板 131 上的 V形凸起 133相连接形成导流板 136b。
图 5显示了导流组合的第四种结构， 在导流组合第三种结构的基础上， 取消正对进气口 16的侧面板 31上的凸起 133， 使与进气口 16正对的侧面 板 131的内侧为平整表面。
图 6显示了导流组合的第五种结构， 在导流组合第一种结构的基础上， 导流板 136a由四片首尾相连的弧形导流板 136c代替，四片弧形导流板 136c 分别对应朝向四个滤气筒 30，四片首尾相连的弧形导流板 136c的横截面呈 菱形结构。 可以理解， 四片首尾相连的弧形导流板 136c也可以由一个具有 四个首尾相连的弧形侧面的长条实体代替， 该四个弧形侧面分别对应朝向 四个滤气筒 30， 该四个弧形侧面的横截面呈菱形结构。
为了可以定期将滤气筒 30取出清理， 在本实施例中， 箱体上部 12和 箱体下部 13—体成型， 箱体下部 13在其中一个侧板 131上设置了一个装 有密封条的侧门 （图未示）， 滤气筒 30从侧门取出。 在其他实施例中， 箱 体上部 12可以可分离地安装在箱体下部 13上或为箱体下部 13的可揭开的 盖子。
可以理解， 滤气筒 30的数量也可以为三个或其它数量， 此时弧形导流 板可以根据滤气筒 30的排列位置关系进行适当的调整， 以使含尘气流分流 后环绕各个滤气筒 30流动。 例如， 当滤气筒 30的数量为三个， 且排列成 正三角形形状时， 可以在三角形中部设置三片首尾相连的弧形导流片， 每 片弧形导流片对应朝向一个滤气筒 30。 在除尘作业时， 含尘气流进入除尘箱 100， 在箱体 10的内部空间的中 部遇到导流板 136a、 136b, 136c, 部分气体被导流板 136a、 136b, 136c分 流， 开始绕滤气筒 30流动， 到侧面板 131后沿箱体 10成型面继续绕滤气 筒 30旋转， 最终形成绕滤气筒 30转动的气流。 另有部分含尘气流穿过导 流板 136a、 136b中部的空隙继续向前， 遇到进气口 16对面的侧面板 131 后， 在侧面板 131 上的导流面被拆分成流向完全相反的两股气流， 在侧面 板 131的导流下形成绕滤气筒 30转动的两股气流， 至此， 进入除尘箱 100 的含尘气流在导流板 136a、 136b, 136c和侧面板 131的分流和导引下， 被 分成了绕滤气筒 30流动的气流。
在含尘气流围绕滤气筒 30转动的过程中， 粉尘被滤气筒 30过滤， 干 净空气穿过过滤层进入滤气筒内部并向上进入除尘箱 100上部并最终排入 大气， 同时， 滤气筒 30外壁上滞留的粉尘被箱体 10上部的高压去尘器 20 定期释放的高压气体清除下来并被让滤气筒 30转动的气流带到除尘箱 100 下方， 通过集灰斗 14、 吸嘴 200， 最终进入垃圾箱。
相较现有技术的下进上排的除尘方式， 本发明的除尘箱 100采取上进 上排的除尘方式提高了过滤除尘的效率， 从而避免源源不断的含尘气流从 除尘箱 100下方涌入并充斥箱体 10内部阻挡被高压去尘器 20清除的粉尘 顺利地落入箱体 10下部的集灰斗 14，有效防止过滤的粉尘不断地被重新搅 入含尘气流中， 降低滤气筒 30上部的含尘气流中的粉尘浓度， 提高滤气筒 30的过滤除尘效率。
本发明的除尘箱 100结构改变了箱内含尘气流的流向， 含尘气流在除 尘箱 100内呈有序流动状态， 更有利于提升滤气筒 30的过滤功能。 从上部 进入除尘箱 100的含尘气流在围绕滤气筒 30流动的同时， 还起到了冲刷滤 气筒 30表面粉尘的作用， 有利于滤气筒 30始终处于较佳的工作状态。
以上所述， 仅是本发明的实施例而已， 并非对本发明作任何形式上的 限制， 虽然本发明已以实施例揭露如上， 然而并非用以限定本发明， 任何 熟悉本专业的技术人员， 在不脱离本发明技术方案范围内， 当可利用上述 揭示的技术内容作出些许更动或修饰为等同变化的等效实施例， 但凡是未 脱离本发明技术方案内容， 依据本发明的技术实质对以上实施例所作的任 何简单修改、 等同变化与修饰， 均仍属于本发明技术方案的范围内。
