Description

一种提高瓦斯抽放泵运行效率的闭式循环系统 技术领域
本发明涉及一种提高瓦斯抽放泵运行效率的闭式循环系统，尤其适用于煤矿井下移动泵站的瓦斯抽采系统。
背景技术
《煤矿瓦斯抽采工程设计规范》规定：高瓦斯矿井或开采有煤与瓦斯突出危险煤层的矿井必须建立瓦斯抽放系统。瓦斯抽放泵作为抽放系统的动力源，对矿井的高效、安全生产起着重要作用。然而，瓦斯抽放泵运行效率低、能耗高，实际效率仅为10～40％，但其占煤矿总耗电量的1/4。该问题与国家对煤矿节能减排要求及我国目前能源紧张现状极不适应。
为此，该领域工程技术人员提出了“一种高分子减阻剂提高瓦斯抽放液环真空泵效率的方法”，即向循环水池内注入高分子减阻剂，利用减阻溶液特有的链状结构，抑制瓦斯抽放泵的涡流损失，从而大幅提高泵的效率的方法。然而，矿用高分子减阻剂溶解性差、用量大，需搅拌充分后才能起到良好的减阻效果，并且需要定量定期添加。现有装置不能与煤矿井下泵站系统完全对接，且不能实现减阻剂的连续配液、即配即用的要求，导致工作程序繁琐、人力物力消耗大，不利于该技术的推广应用。
发明内容
木发明目的是克服已有技术中的不足之处，提供一种系统简单，操作方便，性能可靠，节约用水，能连续工作，并能使减阻剂充分溶解的提高瓦斯抽放泵运行效率的闭式循环系统。
技术方案：提高瓦斯抽放泵运行效率的闭式循环系统，包括气动隔膜泵、高分子减阻溶液罐、瓦斯抽放泵、潜水泵和压风管。所述的气动隔膜泵进液口与高分子减阻溶液罐的出液口相连，气动隔膜泵出液管通入循环水池内。所述的高分子减阻溶液罐内部设有气动搅拌器，顶部设有加料漏斗。所述潜水泵出液口通过三通分别与高分子减阻溶液罐进液口和瓦斯抽放泵进液口连接，瓦斯抽放泵排液管接入循环水池。所述压风管通过三通分别连接气动隔膜泵和气动搅拌器，为其提供动力。
所述的高分子减阻溶液罐出液口处设有钢丝网，钢丝网网孔目数为30～50目。
本发明用于提高瓦斯抽放泵运行效率循环系统，适用于煤矿井下瓦斯抽放移动泵站系统，可实现与井下泵站系统的完全对接。本发明利用已有的压风系统，为高分子减阻剂的充分溶解和添加提供动力；系统与压风管路和潜水泵供水管路相连，减阻剂可连续配液、即配即用，不需中途停顿配制高浓度减阻溶液，能实现连续作业，同时可避免因接井下水管外界水所导致的循环水池内减阻剂浓度不易控制的难点，并节约大量水源，实现闭式循环；通过调压阀和调节阀，简便地实现了搅拌器的搅拌速度控制，以及注入减阻溶液流量的控制，使高分子减阻溶液罐内液位高度得到平衡；通过高分子减阻溶液罐与管路连接处设有钢丝网，可以阻止未溶解的减阻剂进入循环水池内，影响减阻效果；本发明体积小，不含电器元件，在井下使用安全可靠，并可大幅提高瓦斯抽放泵的运行效率。

具体实施方式
下面结合附图和实施例，对本发明作进一步的说明。
附图所示，该系统主要由压风管1，气动隔膜泵13，高分子减阻溶液罐9，潜水泵16，瓦斯抽放泵21等组成。所述的气动隔膜泵13的进液口与高分子减阻溶液罐的出液口通过连接管10相连，气动隔膜泵出液管14通入循环水池15内。所述的高分子减阻溶液罐9内部设有气动搅拌器7，顶部设有加料漏斗8。所述潜水泵16的出液管17通过三通19分别与高分子减阻溶液罐进液口和瓦斯抽放泵进液口连接，该三通的两个出口分别设有调节阀I18和调节阀II20。瓦斯抽放泵排液管22接入循环水池15。所述压风管1依次连接管路变径2，透明胶管I3，气动胶管三通4，气动胶管三通4的一个出口通过透明胶管II、调压阀I连接气动搅拌器7。气动胶管三通4的另一个出口通过透明胶管III11、调压阀II12连接气动隔膜泵13。
工作原理：关闭调压阀II12，打开调压阀I6，压风管1中的高压空气带动气动搅拌器7高速旋转，同时，通过加料漏斗8向高分子减阻溶液罐9中添加高分子减阻剂。待减阻剂充分溶解后，打开调压阀II12，使压风管1中的部分高压空气带动气动隔膜泵13运转，使溶解的高分子减阻溶液通过连接管10、气动隔膜泵出液管14排向循环水池15内，与此同时，打开调节阀I18，使潜水泵出液管17中的部分水流向高分子减阻溶液罐9中。通过调节调压阀II12和调节阀I18的相对开度，使高分子减阻溶液罐9中的液位保持平衡。在此过程中，仍然不断定量地加料，使高分子减阻溶液罐9中的溶液浓度保持恒定。潜水泵出液管17中的另一部分水则通过管路供给瓦斯抽放泵21，潜水泵16也起到了对减阻溶液二次搅拌混匀的作用。瓦斯抽放泵排液管22将从泵中排出的液体送入循环水池内。当循环水池内的高分子减阻剂浓度达到最佳减阻浓度时，停止加料，此时可实现瓦斯抽放泵运行效率的大幅提高。这样就实现了瓦斯抽放泵工作介质的闭式循环。
