Denoising and tail gas removing isolation room for automotive drum tests

Abstract

The invention discloses a denoising and tail gas removing isolation room for automotive drum tests. The denoising and tail gas removing isolation room comprises a working chamber which is internally provided with a drum test platform, and the working chamber comprises two right opposite automatic doors; walls of the working chamber are sound insulation walls, and each sound insulation wall comprises a perlite sound absorption board, a vacuum glass layer and a cement and sawdust sound absorption board which are sequentially arranged from inside to outside; the portion between each perlite sound absorption board and the corresponding vacuum glass layer is filled with glass wool, and the portion between each vacuum glass layer and the corresponding cement and sawdust sound absorption board is filled with glass wool; a temperature adjusting device, a centrifugal fan, a filtering device and a three-way catalysis device are further arranged in the working chamber, an air inlet of the centrifugal fan is right opposite to the drum test platform, and an exhaust duct of the centrifugal fan is sequentially communicated to the filtering device and the three-way catalysis device. The denoising and tail gas removing isolation room is used for solving the problems of large noise pollution and tail gas pollution caused in a workshop in the existing drum test process and achieving the purposes of reducing the noise pollution and tail gas pollution in the workshop.

Description

technical field [0001] The invention relates to the field of motor vehicle testing, in particular to a noise reduction and exhaust gas isolation chamber for automobile drum tests. Background technique [0002] Automobile braking performance is an important indicator and must-check item of the technical conditions of automobile operation safety, which is directly related to road traffic safety. Among the traffic accidents of automobiles, the proportion of accidents caused by the technical failure of the braking system is very large. Therefore, the national standard GB7258-2004 "Technical Conditions for Motor Vehicle Operation Safety", GB18565-2001 "Comprehensive Performance Requirements and Inspection Methods for Commercial Vehicles", GB / T16739.1-2004 "Opening Conditions for Automobile Maintenance Industry Part 1: Complete Vehicles "Maintenance Enterprise" and other standards require mandatory inspection of the braking performance of automobiles. GB7258 stipulates that road...
