A synthetic leather waste gas collection device and its use method

Abstract

A synthetic leather exhaust gas collection device and its use method, the side of the air storage chamber close to the air outlet is provided with an air blocking valve for blocking air, and the inner wall of the right end of the air storage chamber is fixedly connected with a fixing seat that can limit the displacement of the air blocking valve , the upper end of the blocking valve is fixedly connected with the fifth rotating shaft, the inner wall of the receiving rod cavity is provided with a chute for the fifth rotating shaft to slide, the upper end of the fifth rotating shaft is fixedly connected with one end of the first spring, the first The other end of the spring is fixedly connected to the inner wall of the top end of the receiving rod cavity, the fifth rotating shaft is rotatably connected to one end of the seventh connecting rod, the other end of the seventh connecting rod is rotatably connected to the fourth fixed shaft, and the fourth fixed The shaft is fixedly connected to the lower left end of the inner wall of the communication chamber at the right end, and the inner wall of the left end of the air storage chamber is slidably connected with a pusher plate, and the right end of the pusher plate is fixedly connected with a pusher plate, and the left end of the pusher plate is opened to be one-way. An air vent for air valve ventilation, and the push rod plate is slidably connected to the inner wall of the upper end of the air storage chamber.

Description

technical field [0001] The invention relates to the field of artificial leather waste gas treatment, in particular to a synthetic leather waste gas collection device and a method for using the same. Background technique [0002] At present, DMF (N,N-dimethylformamide), toluene, methyl ethyl ketone and other toxic and harmful gases in the production process of synthetic leather are now advocating environmental protection, and often the gases must be processed before they can be released into the atmosphere. Commonly used waste gas absorption, Treatment devices include packing absorption towers, etc. However, the amount of waste gas produced during the processing of synthetic leather is uneven, and the spray device in the absorption tower continues to spray. If the waste gas reaches a certain concentration and is not treated uniformly, it will easily cause waste of resources in the absorption tower. At present, the processing technology often needs to collect the exhaust gas t...

[0002] At present, DMF (N,N-dimethylformamide), toluene, methyl ethyl ketone and other toxic and harmful gases in the production process of synthetic leather are now advocating environmental protection, and often the gases must be processed before they can be released into the atmosphere. Commonly used waste gas absorption, Treatment devices include packing absorption towers, etc. However, the amount of waste gas produced during the processing of synthetic leather is uneven, and the spray device in the absorption tower continues to spray. If the waste gas reaches a certain concentration and is not treated uniformly, it will easily cause waste of resources in the absorption tower. At present, the processing technology often needs to collect the exhaust gas to a certain concentration, and then pass it into the absorption tower for further treatment. There is no device in the current process that can automatically adjust the exhaust gas to a certain concentration and then discharge it.
