The invention belongs to the technical field of atmospheric detection devices, and discloses an atmospheric sampling detector, which includes a box body, a cover plate is hinged on the upper side of the box body, a cylinder is arranged in the box body, an outer disk is fixedly connected to the upper end of the cylinder, and The upper end of the disc is provided with a card slot, and the clamp is installed in the card slot, and the sample film is clamped by the clamp. Both sides of the outer disc are provided with an air inlet channel, and the air inlet channel is provided with a second opening. The negative pressure pump and the first motor, the lower end of the air intake passage are connected to the air intake pipe of the negative pressure pump, and a push-pull mechanism is arranged in the box, and the push-pull mechanism is used to insert the clamp from the second opening to completely cut off the air intake passage The inner cavity of the box or return the fixture to its original position; the air intake channel is provided with a solenoid valve and a gas flow sensor, and a control module is installed outside the box. The device can not only improve the collection efficiency, but also perform data comparison, reduce the measured concentration error, improve the accuracy of atmospheric sampling and detection, and can also automatically replace the sampling membrane, reducing labor.
Description
technical field [0001] The invention relates to the technical field of atmospheric detection devices, in particular to an atmospheric sampling detector. Background technique [0002] With the aggravation of environmental pollution and people's increasing attention to environmental quality and air quality, the detection of air quality has become more and more important. Atmospheric detection can not only provide various pollution degree indicators, but more importantly, remind people Sources and how to strengthen the control of pollution sources and the protection of the environment. Atmospheric sampling includes harmful gas sampling and particulate matter sampling. When particulate matter is sampled, a certain volume of air passes through the sampling membrane, and the particulate matter suspended in the air is blocked on the sampling membrane. The added mass of the membrane and the volume of air passing through the filter membrane determine the mass concentration of total s...
