Device for measuring concentration value of particulate matters in gas on site

The invention discloses a device for measuring the concentration value of particulate matter in gas on site. The device comprises a gas inlet pipe, a heating device communicated with the gas inlet pipe, a sensor communicated with the heating device, a flowmeter communicated with the sensor and a gas outlet nozzle communicated with the flowmeter. The heating device is also connected with a pitot tube. The device can accurately measure the concentration of particulate matters in flue gas and the flow velocity of the flue gas, facilitates comparison of flue gas emission, accurately verifies the working efficiency of some dust removers and equipment of desulfurization and denitrification manufacturers, and improves the reliability and feasibility of environmental protection law enforcement data. 本申请公开了一种当场测出气体中颗粒物浓度数值的装置，包括：进气管、与进气管连通的加热装置、与加热装置连通的传感器、与传感器连通的流量计、与流量计连通的出气嘴；所述加热装置上还连接有皮托管。本装置能够准确的测出烟气中颗粒物的浓度以及烟气流速，便于烟气排放的对比，对一些除尘器和脱硫脱硝厂家的设备的工作效率进行准确的验证，以及环保执法数据的可靠性、可行性。
