Abstract

A tester for testing the performance of a new material degrading tail gas relates to a testing unit. The invention solves the problem of limited usage range, light-tightness of a gas reaction chamber, unstable testing result due to the change of temperature and environment, high cost of equipment and complicated structure, all of which are caused by that the prior test equipment does not have light conditions necessary for light-catalyzed reaction. A gas reaction chamber (12) of the invention is made from light transmissible materials, and consists of a cover gasket (1) and a reaction chamber vessel (14) which are in closed connection with each other; a sensor probe (13) is inserted in a jack (4) on the cover gasket (1), and is connected with a tail gas analyzer (10); a vacuum air pump (9) is connected with the bottom of the reaction chamber vessel (14) through a connecting hose (15). The invention has the advantages of unlimited usage range, direct use of solar light source as the reaction condition by the gas reaction chamber, accurate testing result, low cost of equipment and simple structure.

Description

technical field [0001] The present invention relates to a test device. Background technique [0002] With the research of new degradable tail gas materials such as photocatalysts, corresponding test and test equipment has also emerged. Among them, the test equipment for tail gas concentration has been developed and put into use. Due to the complexity of the situation, its related research and development work is still in its infancy. The following several test equipments are provided in the prior art: 1. The P7510 exhaust gas catalytic reaction device released by U.S. Cusson Company can be used to test the purification efficiency of the catalyst and the flow rate of the gas. Ceramic honeycomb carrier, put various catalysts to be tested on the carrier respectively, and test the concentration change of each harmful substance in the automobile exhaust flowing through the catalytic reactor, so as to obtain the catalytic conversion efficiency of each catalyst. However, the scop...
