Method for improving smoke discharge height of chimney

Abstract

The invention discloses a method for improving the smoke discharge height of a chimney. The method is characterized by comprising the steps of a, setting up a supercharging area at the top cavity of the chimney, and compressing smoke ascending to the supercharging area; and b, setting up a smoke vortex ring generating part above the supercharging area, generating smoke vortex when the smoke compressed in the supercharging area passes through the smoke vortex ring generating part, upwards spraying the smoke out of the chimney and then discharging into atmosphere. An upper fixing plate is arranged in the supercharging area and is used to separate the top cavity of the chimney, a lower movable plate is arranged below the upper fixing plate and moves longitudinally in a reciprocating way to compress the smoke between the upper fixing plate and the lower movable plate, and a center opening is formed on the upper fixing plate to serve as the smoke vortex ring generating part. By adopting the method, the smoke discharge height can be increased to more than two times that of an existing chimney with the same size, thus contributing to improve the urban air environment and achieving good social and economic benefits.

Description

technical field [0001] The invention relates to a method for raising the smoke emission height of a chimney. Background technique [0002] Chimneys are currently the main facilities for emitting smoke and dust, and are also an important source of pollution for the atmospheric environment around cities and towns. Although measures have been taken to reduce dust particles and remove sulfur and denitrification, the exhausted smoke still contains a large amount of fine dust and toxic and harmful gases. In order to prevent the smoke and dust from settling around the chimney and causing severe local environmental pollution, the method of increasing the height of the chimney is often used to discharge the smoke and dust to a higher air, and use the high-altitude airflow to accelerate the spread of the smoke and dust. However, due to technical and cost reasons, the construction height of the chimney will be limited, and the smoke cannot be discharged to a higher height. In additio...

However, due to technical and cost reasons, the construction height of the chimney will be limited, and the smoke cannot be discharged to a higher height

In addition, there is a method of increasing the flow rate of smoke and dust in the chimney. Although this method helps to increase the discharge height of smoke and dust, it is limited by boiler specifications, etc., and due to the turbulent effect of smoke and dust entering the atmosphere, the effect of increasing the discharge height of smoke and dust quite limited
