Waste gas treatment device for plastic master batch processing

Abstract

The utility model provides a waste gas treatment device for plastic master batch processing, and relates to the field of waste gas treatment. A liquid inlet pipe is communicated with a water tank, and the bottom end surface of a cover plate is fixedly connected with a spraying seat; the waste gas treatment device solves the problems that a waste gas treatment device in the prior art generally leads out a part of waste gas and then supplies the waste gas into processing equipment for heating during waste gas treatment, but due to lack of an effective circulation structure, when gas is subjected to heating operation, the heating operation cannot be efficiently performed, and the utilization rate of the waste gas is relatively low. When waste gas generated during plastic master batch processing is recycled through the recycling pipe, recycled liquid can be collected through the circulating pipe of a spiral structure synchronously, the flowing speed of air can be reduced through slow flow of the circulating pipe, and therefore when the circulating pipe is installed on the outer side of processing equipment, the circulating pipe can be used for recycling waste gas generated during plastic master batch processing. And continuous and stable temperature increasing operation can be carried out through the arrangement of the circulating pipe, so that the purpose of waste heat recovery is achieved.
