本实用新型涉及一种风量检测取压装置，尤其是一种具有自清灰装置的风量检测取压装置，属于锅炉检测装置领域。The utility model relates to an air volume detection and pressure-taking device, in particular to an air volume detection and pressure-taking device with a self-cleaning device, belonging to the field of boiler detection devices.
背景技术Background technique
目前，测量电厂使用的锅炉风管内的风量检测取压装置，利用风量检测取压装置全压和静压之差与风量关系，测算出风管内的风量。但是由于风道内的气流中粉尘较大，因此，为了不堵塞风量检测取压装置的管道，需要清扫管道内的粉尘，但由于风量检测取压装置安装于管道上，清理时若要拆卸则费时费力且耽误生产，现有风量检测取压装置上安装的自清灰装置为悬置在取压管内的细杆，细杆在气流的作用下做无序摆动，敲击取压管壁起到清灰作用，但是清灰效果不理想。At present, the air volume detection and pressure taking device in the boiler air duct used in the power plant is measured, and the air volume in the air duct is calculated by using the relationship between the difference between the total pressure and the static pressure of the air volume detection and pressure acquisition device and the air volume. However, due to the large dust in the airflow in the air duct, in order not to block the pipeline of the air volume detection and pressure taking device, the dust in the pipeline needs to be cleaned. However, since the air flow detection and pressure taking device is installed on the pipeline, it will take time to disassemble it during cleaning. It is laborious and delays production. The self-cleaning device installed on the existing air volume detection and pressure taking device is a thin rod suspended in the pressure taking pipe. Dust removal effect, but the dust removal effect is not ideal.
有鉴于此特提出本实用新型。In view of this, the utility model is proposed.
