Description

一种瓦斯抽采管路排水除尘装置 技术领域
本发明涉及瓦斯抽采技术领域，尤其是一种用于瓦斯抽采管路上的瓦斯抽采气体排水除尘装置。
背景技术
瓦斯灾害严重制约着矿井的安全高效生产，瓦斯爆炸同样会造成大量的人员伤亡和财产损失。但瓦斯同时也是一种清洁资源，为有效防治瓦斯灾害，并实现瓦斯的高效利用，制定了《防治煤与瓦斯突出规定》、《瓦斯抽采达标暂行规定》、《煤矿瓦斯抽放规范AQ1027》等一系列瓦斯防治标准和技术规范，并建立了“通风可靠、抽采达标、监控有效、管理到位”的煤矿瓦斯治理工作体系。但是抽采过程中受井下条件的限制，钻孔内会同时抽出水和粉尘，抽出的水和粉尘不但会增加抽采阻力，同时对抽采管路中嵌入式的检测仪表造成影响。例如皮托管或孔板流量计、瓦斯温度和浓度传感器等检测仪器，影响瓦斯抽采参数的准确计量，因此在抽采钻孔孔口处需要进行排水降尘处理。针对瓦斯抽采管路中气体混杂有水和粉尘的问题，目前通常使用矿用负压放水器解决。但是矿用负压放水器需要人工定期维护，并且对于含有粉尘气体的净化效果较差，粉尘会影响瓦斯抽采参数的准确计量，并影响瓦斯参数检测装置的使用寿命。为此，需要提供一种排水除尘装置，对瓦斯抽采管路上的瓦斯气体进行处理，有效消除其中的粉尘和水，并实现粉尘和水的自动排放。

发明实施例
本发明的实施方式
结合图1至图2所示，本发明提供的一种瓦斯抽采管路排水除尘装置具体实施方 式如下。
在瓦斯抽采管路中，由于抽采瓦斯气体中含有粉尘和水，从而影响瓦斯抽采管路上的检测仪器，提供一种瓦斯抽采管路排水除尘装置，实现了粉尘和水的自动排放。其集气机构包括采气管1、集气箱2和进气管3，采气管1和瓦斯抽采的管路相连，采气管1汇集气体于集气箱2内。其中集气箱2为变径管，采气管1连接大直径集气箱2的一侧，进气管3连接集气箱2的小直径集气箱2一侧，从而使各个瓦斯抽采管的抽采气体汇合导入，保证气体了流动压力。
该装置还包括除尘机构和排水除尘机构，其中的除尘机构将瓦斯气体与粉尘和水分离，将纯净的瓦斯气体通过导流管导出，除尘机构将分离出的粉尘和水排入排水除尘机构中，排水除尘机构自动进行排水，使用该装置能够提高瓦斯浓度检测的精度并延长瓦斯浓度检测仪的寿命，提高了瓦斯抽采纯度，防止抽采瓦斯中混杂的粉尘和水对管路及设备的损害。集气箱2通过进气管3和除尘机构相连，抽采气体通过进气管3保持输送压力，送入除尘机构进行尘气分离，以及水气分离。其除尘机构具体包括除尘腔室5和导流管4，排水除尘机构设置在除尘机构的下方。导流管4设置在除尘腔室顶部的中轴线上，除尘腔室5的上部呈圆筒状，除尘腔室5的下部呈圆锥状。进气管3沿除尘腔室5切向将气体送入除尘腔室5，除尘腔室5的下部出口处设置有水尘收集管6，水尘收集管6沿除尘腔室5的轴线布置，水尘收集管6的下端和蓄水箱8的上部相连。气流沿除尘腔室5上部切向进入除尘腔室，在气体沿除尘腔室5上部的筒壁内部运动，其中的粉尘和水受离心力的作用与腔室内壁产生碰撞，失去能量被捕获然后下落，随着外气旋向下运动，进入锥形区域，气压平衡的作用下，形成有除尘后的气体在轴部构成的内气旋，最终除尘厚度气体从导流管被抽走。
排水除尘机构包括蓄水箱8、导杆10、动力浮漂11、上套筒12、连接盘、平衡浮漂14、下套筒17、活塞阀18、固定杆20和排水管19，连接盘包括连接绳15、上连接盘13和下连接盘16，固定杆20沿排水管19内直径设置，导杆10固定在固定杆20的中部，导杆10固定在蓄水箱8的轴线上，动力浮漂11、平衡浮漂14和连接盘均套设在导杆10上，上套筒12连接动力浮漂11和上连接盘13，平衡浮漂设置在上连接盘13和下连接盘16之间，下套筒连接活塞阀18和下连接盘16。蓄水 箱8的横截面面积由水尘收集管连接端向排水管连接端逐渐减小，其中蓄水箱8可以是呈圆锥状、圆台状、多边锥状或多边台状。导杆10的上端设置有防尘盖9，防尘盖9呈伞状，防尘盖9的面积大于套筒的直径，从而避免粉尘和水进入上套筒或者下套筒，导杆10和固定杆20相互垂直。平衡浮漂14在水中的最大浮力等于平衡浮漂14、下连接盘16、下套筒17和活塞阀18的重力之和。
在蓄水箱8内，初始状态下，上连接盘13在重力作用下压在平衡浮漂14上，柔性的连接绳15处于松弛状态；瓦斯抽采管路排水除尘装置工作一段时间后，蓄水箱8内液面持续上升至没过平衡浮漂14后，下套筒17连接的平衡浮漂14、下连接盘16、活塞阀18受到平衡浮漂14提供的浮力，此时形活塞并未打开；然后蓄水箱8内液面继续上升，当水升至动力浮漂11处，动力浮漂11受到浮力开始上升，柔性连接绳15逐渐张紧，连接绳15张紧后，由于液面继续上升，动力浮漂11在浮力作用下继续上升，连接绳15开始带动着下连接盘16向上运动，同时下连接盘带动平衡浮漂14、下套筒17及活塞阀18向上运动，排水管19被打开，底部积尘和水被排出；最后随着液面下降，动力浮漂11开始下降，连接绳15逐渐松弛，当动力浮漂11带动上连接盘下降至与平衡浮漂14接触后，平衡浮漂14在上连接盘13的压力下带动活塞阀18下降封闭排水管19。因除尘腔室5内气体流速大，容器内为负压，当形活塞打开后，液体无法全部流出，起到液封的作用，水尘排出管与大气连通后，不会有外界气体被吸入装置。
瓦斯抽采管路排水除尘装置，可实现对瓦斯抽采管路的持续排水除尘，且可以自动排污，高效、方便、经济效益好。
当然，上述说明并非是对本发明的限制，本发明也并不仅限于上述举例，本技术领域的技术人员在本发明的实质范围内所做出的变化、改型、添加或替换，也应属于本发明的保护范围。

  6. 根据权利要求1所述的一种瓦斯抽采管路排水除尘装置，其特征在 于，所述蓄水箱呈圆锥状、圆台状、多边锥状或多边台状。
  7. 根据权利要求1所述的一种瓦斯抽采管路排水除尘装置，其特征在于，所述导杆的上端设置有防尘盖，导杆和固定杆相互垂直。
  8. 根据权利要求1所述的一种瓦斯抽采管路排水除尘装置，其特征在于，所述平衡浮漂在水中的最大浮力等于平衡浮漂、下连接盘、下套筒和活塞阀的重力之和。
  9. 根据权利要求1至8任一项所述的一种瓦斯抽采管路排水除尘装置，其特征在于，所述蓄水箱内，初始状态下，上连接盘在重力作用下压在平衡浮漂上，柔性的连接绳处于松弛状态；瓦斯抽采管路排水除尘装置工作一段时间后，蓄水箱内液面持续上升至没过平衡浮漂后，下套筒连接的平衡浮漂、下连接盘、活塞阀受到平衡浮漂提供的浮力，此时形活塞并未打开；然后蓄水箱内液面继续上升，当水升至动力浮漂处，动力浮漂受到浮力开始上升，柔性连接绳逐渐张紧，连接绳张紧后，由于液面继续上升，动力浮漂在浮力作用下继续上升，连接绳开始带动着下连接盘向上运动，同时下连接盘带动平衡浮漂、下套筒及活塞阀向上运动，排水管打开，底部积尘和水被排出；最后随着液面下降，动力浮漂开始下降，连接绳逐渐松弛，当动力浮漂带动上连接盘下降至与平衡浮漂接触后，平衡浮漂在上连接盘的压力下带动活塞阀下降封闭排水管。
