Abstract

The invention discloses a gas-state pollutant generating device and method for detecting performance of an air purifier. The device comprises a constant-flow pump, the constant-flow pump is connected with the liquid inlet of an atomization nozzle, the air inlet of the atomization nozzle is connected with a floater flowmeter, atomized liquid enters an evaporation chamber, an electric heating band is arranged outside the evaporation chamber, a temperature comptroller is arranged on the electric heating band, a heat preservation layer is arranged outside the electric heating band, and the outlet of the evaporation chamber is connected with a purifier test system. The gas-state pollutant generating device and generating method are simple in principle, low in cost, suitable for various pollutants which are formed by liquid evaporation and generate gas, economical and practical. A computer can remotely control the rotating speed of the constant-flow pump, control and adjust the occurrence number of the pollutants and adjust the temperature of the electric heating band, a certain quantity of gas-state pollutants can be generated, and the operation is simple and convenient.

Description

technical field

[0001] The invention relates to a device and method for generating gaseous pollutants used for performance testing of an air purifier, in particular to a device and method for generating gaseous pollutants used in a road vehicle filter test system. Background technique

[0002] With the rapid development of my country's economy, my country's car ownership is increasing rapidly. By the end of 2011, there were 73.2677 million privately owned vehicles in my country, which was 7.5 times that of 2002, increasing at a compound annual growth rate of 25% in the past ten years. When the pollutants emitted by automobiles become a problem of increasing concern, the interior environment of automobiles has also attracted more and more public attention. Since March 2012, the national standard GB / T27630-2011 "Guidelines for the Evaluation of Air Quality in Passenger Cars" has been implemented. 3 ), toluene (≤1.10mg / m 3 ), xylene (≤1.50mg / m 3 ), ethylbenzene (≤1.50mg / m ...
