Advanced dust-removing and demisting device

一种深度脱尘除雾装置

Abstract

本发明公开了一种深度脱尘除雾装置,更具体地说,是一种适用于含有大量雾滴的饱和烟气的脱尘除雾装置。一种深度脱尘除雾装置,所述装置的主要工作原理如下:利用烟气中含有的大量雾滴液滴的特点,在烟气高速的运动中实现雾滴液体颗粒相互之间,雾滴液体颗粒与粉尘颗粒之间,碰撞而凝聚成较大的颗粒后沉降下来;雾滴液体颗粒与粉尘固体颗粒与装置内的持液层充分接触后,被液体捕悉实现分离;雾滴液体颗粒与粉尘固体颗粒随烟气高速旋转,利用与烟气的密度差实现离心分离,被抛向装置内壁表面,与装置壁面附着的液膜层接触后湮灭。本发明的优点是在在较低的运行成本与投资成本下,实现高效的脱尘除雾,结构简单可靠无堵塞风险,设备轻便安全。
The invention discloses an advanced dust-removing and demisting device, and particularly relates to a dust-removing and demisting device which is suitable for saturated flue gas containing a great deal of fog drops. The advanced dust-removing and demisting device has a main working principle as follows: collision among fog drop liquid particles and between fog drop liquid particles and dust particles can be realized during high-speed motion of flue gas based on the characteristic that the flue gas contains a great deal of fog drops and liquid drops, so that larger particles are formed by agglomeration and then settle; the fog drop liquid particles and the dust solid particles are in full contact with a liquid-containing layer in the device, and then separation is realized by liquid trap; the fog drop liquid particles and the dust solid particles rotate at high speed along with the flue gas, centrifugal separation is realized by virtue of the density difference between the fog drop liquid particles and the flue gas as well as between the dust particles and the flue gas, and then the fog drop liquid particles and the dust solid particles are thrown onto the surface of the inner wall of the device and are removed after contacting a liquid film layer attached onto the wall surface of the device. The advanced dust-removing and demisting device has the advantages that efficient dust removing and demisting can be realized under the conditions of low running cost and investment cost; the device is simple and reliable in structure and free of a risk of blocking, and is also portable and safe.
