The invention belongs to the technical field of
waste gas treatment, and particularly relates to a rubber
vulcanization waste gas collecting device. The rubber
vulcanization waste gas collecting device comprises a main pipeline, the main pipeline is connected with a waste gas treatment device through a fan, a plurality of
branch pipelines are further connected to the main pipeline, the main pipeline and the
branch pipelines are correspondingly connected with a vertical
pipe, the lower section of the vertical
pipe is connected with a gas collecting cover through a connecting
system, an openingof the gas collecting cover faces downwards and is located on a waste gas emission source, the connecting
system comprises a variable-
diameter pipeline joint and a stretchable pipeline, the upper endof the variable-
diameter pipeline joint is connected with the vertical
pipe, the lower end of the variable-
diameter pipeline joint is connected with the upper end of the stretchable pipeline, and thelower end of the stretchable pipeline is connected with the gas collecting cover. According to the rubber
vulcanization waste gas collecting device, the stretchable pipeline is connected with the gascollecting cover, the angle and the position of the gas collecting cover can be changed in the using process, and the arrangement precision of the pipelines at the early stage can also be relaxed, sothat the installation process of the gas collecting cover is convenient, moreover, a buffering function is achieved, and the gas collecting cover is not prone to
impact.
