图2-图4为本发明提出的第一个实施例的结构示意图，其中图2为整体结构示意图，图3为局部结构 示意图，图4为局部结构放大示意图。
图中显示，与现有技术不同的是，本例中，将活性炭缓冲罐21及喷射系统置于第一独立空间A，在缓冲罐及喷射系统之前新增设卸料装置及前端贮存系统并将其置于第二独立空间B，在第一独立空间A与第二独立空间B之间设置螺旋输送机，活性炭从第二独立空间B由螺旋输送机输送至第一独立空间A。
图2显示，新增设卸料装置包括活性炭罐车1及卸料管道2，在卸料管道2上设置电动阀2.1。
前端贮存系统包括活性炭储存仓8、按照活性炭的流动方向，在活性炭储存仓8底部依次设置手动插板阀10、电动旋转阀11、膨胀节12、螺旋输送机13；在活性炭储存仓8的底部还设置有电动振打器9；
图2及图3显示，在活性炭储存仓8的仓体外壁还设置有高料位报警器23A2及低料位报警器23B2；
图3及图4显示，将现有技术中安装在喷射系统的就地温度计24.1、就地压力表24.2及远程温度计及远程压力表25更改为安装在活性炭储存仓8顶部设置；同时，在活性炭储存仓8顶部新增脉冲式布袋除尘器6及压力释放阀7。同时，还增设置氮气供给系统，氮气供给系统包括氮气瓶3及氮气管道3.1及按照气流流动方向依次设置的手动球阀4及电动球阀5；氮气管道3.1一端与氮气瓶3连接而另一端与所述活性炭储存仓8连接，氮气从氮气瓶3经氮气管道3.1输送到活性炭储存仓8。
本例中，活性炭经活性炭罐车1打入活性炭储存仓8，活性炭从活性炭储存仓8底部出来，经手动插板阀10、电动旋转阀11、膨胀节12、螺旋输送机13输送到活性炭缓冲罐21；从活性炭缓冲罐21出来的活性炭依次经重料斗14、双螺杆输送机15之后进入文丘里喷射器20。活性炭进入文丘里喷射器20之后，在喷射系统的作用下经喷射管道20.1被喷射到活性炭用户26。
本例中，在活性炭储存仓8顶部还设置压力和温度测点，若压力超过2kpa，打开布袋除尘器风机6，维持仓内微负压；若温度超过80℃，打开氮气供给系统的电动球阀5，往活性炭储存仓8中通入氮气，防止仓内温度过高混合氧气发生燃烧或者爆炸。正常情况下，活性炭储存仓8底下的手动插板阀10保持常开。
活性炭缓冲罐21的高料位报警器23A1、低料位报警器23B1的信号与电动旋转阀11进行连接，通过高料位报警器23A1、低料位报警器23B1的信号控制电动旋转阀11的打开或关闭。活性炭储存仓8的高料位报警器23A2及低料位报警器23B2的信号与电动旋转阀2.1进行连接，通过高料位报警器23A2、低料位报警器23B2的信号控制电动旋转阀2.1的打开或关闭。从而使活性炭储存仓8及活性炭缓冲罐21中的活性炭料位始终保持在可控范围内。
图2显示，活性炭从第二独立空间B由螺旋输送机13输送至第一独立空间A。由于A空间与B空间分开设置，并且螺旋输送机13采用密封输送，因此，可以有效的防止缓冲贮存(缓冲罐)及喷射系统作业空间出现扬尘。防止发生意外。
