Heating device of ultra-low smoke instrument

The utility model relates to the technical field of smoke instruments, in particular to an ultra-low smoke instrument heating device which comprises a heating chamber, the bottom face and the top face of the heating chamber are respectively communicated with an air inlet pipe and an air outlet pipe in a sealed mode, and a plurality of transversely-arranged heating plates are arranged in the heating chamber. The heating plates are arranged up and down, and the connecting sides of every two adjacent heating plates are located on the opposite sides. When the device is used, the passing speed of gas can be slowed down, so that the time of the gas in the heating chamber can be ensured, the gas can be effectively heated, and water vapor in the gas is prevented from influencing measured data. 本实用新型涉及烟尘仪技术领域，具体地说是一种超低烟尘仪加热装置，包括加热室，所述加热室的底面和顶面分别密封连通有进气管和出气管，所述加热室内设置有数个横向布置的加热板，所述加热板上下布置且相邻两加热板的之间连接侧均位于相反侧。本装置在使用时，能减缓气体的通过速度，从而能保证气体在加热室内的时间，进而能有效的对气体进行加热，防止气体内存在水蒸气影响测量数据。
