Abstract

Relating to environmental protection technology, this application provides a volatile gas trap and a volatile gas purge and trap device. The volatile gas trap includes a trap tube, a heat conduction layer, and a heating layer. The trap tube includes an adsorption agent, the collection pipe is U-shaped, the heat conduction layer is coated on the outside of the collection pipe, the heating layer includes electric heating wires, and the heat generated by the electric heating wires is conducted to the heat transfer layer through the heat conduction layer. The collecting tube; the electric heating wire includes an electric heating wire, an insulating and heat-conducting film and a tube shell, the shell includes an inner lumen, the heating wire runs through the inner lumen, and the insulating and heat-conducting film is coated on the Outside the heating wire, the insulating and heat-conducting film is located between the tube shell and the heating wire. The trap with a new structure adopts a new type of electric heating tube, which can realize rapid heating, and the measured temperature rise rate can reach 30 degrees Celsius / second, which can significantly improve the desorption efficiency of the trap.

Description

technical field [0001] The present application relates to environmental protection technology, in particular to a volatile gas trap and a volatile gas purging and trapping device. Background technique [0002] A purge and trap device is an instrument used to analyze volatile organic compounds in a sample. When working, the purge and trap device uses the purge gas to continuously pass into the purge tube to bubble, so as to drive the volatile components in the sample to escape with the purge gas, and then concentrate through the trapping device equipped with adsorbent; After purging for a certain period of time, the gas in the trapping device is introduced into the analyzer for analysis. [0003] In the existing trapping device, a heating device is generally installed in the trapping tube, so as to heat the adsorbent in the trapping tube during the desorption step, thereby desorbing the volatile gas in it, but the desorption efficiency of the existing trapping device is rela...
