The sampling head includes sampling pipe and the filter of setting in the sampling pipe, and the sampling mouth has been seted up to sampling pipe one side, and the sampling mouth link up with the air inlet of filter, and the filter is the cylindrical shape that the axial link up, and the air inlet of filter is its axial one end, and appearance trachea connection is to the lateral wall of filter. The invention evenly distributes a plurality of detection points on the cross section of the flue, each sampling head is respectively connected with a sample gas pipe, the sample gas pipes are communicated with the detection equipment outside the flue, the nitrogen content in the flue gas of each sampling head area is detected one by one, and the regional monitoring of the flue is really realized.

摘要：【中文】本发明公开一种高连接和密封可靠性纯铂针水电极的结构方案及其制作方法。该水电极的不锈钢嵌件一端为电极接线端，该端从端面向内部延伸设置有电极连接孔；另一端为铂针安装端，该端开设有螺纹孔用于铂针的压紧固定。不锈钢止松件的内孔插入铂针，通过止松件和不锈钢嵌件铂针安装端配合压紧铂针；压紧垫片预装后具有倒楔形结构，包胶注塑电极本体后其具有结构防松作用，并且可保证包胶时注塑的封胶可靠。内部O型圈处于不锈钢嵌件和电极本体的结合面上，具有进一步提高防水密封效果的作用；该水电极通过包胶注塑的方法得到电极本体。本发明具备连接和密封的高可靠性特点，能保证水电极长期使用下优异的电接触性能和密封性能。 【EN】The invention discloses a structural scheme of a pure platinum needle water electrode with high connection and sealing reliability and a manufacturing method thereof. One end of the stainless steel insert of the water electrode is an electrode wiring terminal, and the end extends inwards from the end surface and is provided with an electrode connecting hole; the other end is a platinum needle mounting end, and the end is provided with a threaded hole for compressing and fixing the platinum needle. The platinum needle is inserted into the inner hole of the stainless steel loosening-stopping piece, and the platinum needle is tightly pressed through the loosening-stopping piece and the stainless steel embedded platinum needle mounting end in a matching manner; the pressing gasket has an inverted wedge-shaped structure after being preassembled, and the encapsulated injection molding electrode body has a structure anti-loosening effect, so that the encapsulation of injection molding during encapsulation can be ensured to be reliable. The inner O-shaped ring is positioned on the combined surface of the stainless steel insert and the electrode body, and has the function of further improving the waterproof sealing effect; the water electrode is obtained into an electrode body by an encapsulation injection molding method. The invention has the characteristics of high reliability of connection and sealing, and can ensure excellent electric contact performance and sealing performance of the water electrode in long-term use.
