AI Technical Summary

Technical Problem

Uneven airflow distribution in traditional exhaust pipes leads to low exhaust gas treatment efficiency, eddies and backflow phenomena, and significant energy loss.

Method used

Design a cement production waste gas emission pipe with a baffle plate. The pipe is a combination of a spiral structure exhaust pipe and a baffle pipe. The diameter of the baffle pipe gradually decreases. It is combined with a ceramic inner wall and rubber pad support, and the outside is covered with thermal insulation cotton to improve the uniformity and stability of airflow.

Benefits of technology

By forcing the exhaust gas to rotate and flow, eddies and backflows are reduced, exhaust gas treatment efficiency is improved, airflow concentration and guidance are enhanced, and energy loss and noise pollution are reduced.

Abstract

This utility model relates to the field of waste gas emission technology and discloses a cement production waste gas emission pipe with a guide plate design. It includes an outer pipe and an inner pipe. A connecting plate is provided on one side of the inner wall of the outer pipe, and the inner pipe is connected to the connecting plate. The inner pipe is composed of a spiral exhaust pipe and a guide pipe. The guide pipe is connected to one end of the exhaust pipe, and one end of the guide pipe is funnel-shaped, meaning the diameter of the guide pipe gradually decreases from the air inlet end to the exhaust pipe. A fixing frame is provided at the end of the outer pipe away from the connecting plate, and an exhaust fan is connected to the fixing frame. The combination of the spiral exhaust pipe and the gradually narrowing guide pipe helps to evenly distribute the airflow and enhance centrifugal force, thereby improving the efficiency of subsequent waste gas treatment.
