Secondary pollution, meanwhile, meet the VOC processing requirements of various runners.
Technical scheme：The VOC dynamic experimental test methods of the present invention, it is characterised in that：Comprise the steps,
(1) VOC gas enter after air compressor machine pressure regulation and enter VOC solvent case supplement VOC solvent through tracheae, then transtracheal enters
Fresh air blending bin is mixed with the gas handled again, is entered temperature and moisture by temp.-humidity measuring apparatus measurement, is passed through VOC concentration
Enter tested VOC adsorption runners after measuring instrument measurement air inlet VOC concentration to be handled；
(2) gas after the processing of VOC adsorption runners measures temperature and moisture by temp.-humidity measuring apparatus, passes through VOC
Concentration measuring apparatus measures outlet VOC concentration, by the presence of stainless steel blower fan, being closed after air quantity measurement and control instrument measurement outlet air quantity
Air is discharged into after lattice, it is unqualified to be handled again into fresh air blending bin；
(3) desorption air-flow is heated by heater, to tested in the presence of high temperature resistant stainless steel blower fan
VOC adsorption runners are desorbed；Desorption air-flow is purified by purifier, Primordial Qi stream carried out by heat reclamation device
Waste heat recovery；
(4) VOC adsorption runners are tested according to the desorption ability of the disposal ability of VOC adsorption runners and VOC adsorption runners
Performance provides test evaluation report.
