Problems solved by technology

In the case of using an atomizing nozzle, since the liquid channel inside the nozzle must have a certain inner diameter, it must not be too thin, so that when the liquid flow rate is small, the spray will appear intermittent pulsation, which will affect the stability of the occurrence

Abstract

The invention discloses a gaseous organic pollutant generator used in an air filter test system, which comprises a liquid container, the outlet of the liquid container is connected with the liquid inlet of a constant-flow pump through a liquid pipeline, and the liquid outlet of the constant-flow pump is sent through a The liquid pipeline is connected with the liquid pollutant inlet of the evaporating chamber, the air inlet of the rotameter is connected with the compressed air, the air outlet of the rotameter is connected with the compressed air inlet of the evaporating chamber through the air pipeline, and a thermocouple is inserted in the evaporating chamber , thermocouples and solid state relays are respectively connected to the temperature controller through wires, the evaporation chamber is a U-shaped structure, and a horizontal bending section is set on the top of one side of the U-shaped structure, and the compressed air inlet is set at the entrance of the horizontal bending section. There are multiple inlets for liquid pollutants and they are arranged on the horizontal bending section, and the vertical port on the other side of the U-shaped structure is used as an outlet for gaseous pollutants. The device adapts to the change of the flow rate of liquid pollutants and ensures the gasification of the liquid.

Description

technical field [0001] The invention relates to a generator of various gaseous chemical pollutants, in particular to a gaseous pollutant generator used for air filter performance testing. 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 3 ), styrene (≤0.26mg / m 3 ), formaldehyde (≤0.10mg / m 3 ), acetaldehyde (≤0....
