复合型除尘器
本申请属于环保设备
,涉及一种除尘器,具体涉及一种复合型除尘器。
技术介绍
除尘器是常见的环保设备,作用是把粉尘从烟气中分离出来,使得废气排放符合环保要求。除尘器种类很多,如袋式除尘器、静电除尘器、旋风除尘器、水雾除尘器等等;各种除尘器各有各的优点,但同时也各有各的缺点需要改进,难以适应多种工况。因此需要研发一些具有两种或两种以上除尘器优点的复合型除尘器,以满足多种工况要求。
技术实现思路
鉴于现有技术中的上述缺陷或不足,期望提供一种复合型除尘器。本申请提供一种复合型除尘器,包括内筒、包围在内筒外的中筒和包围在中筒外的外筒;内筒、中筒、外筒为同轴设置的圆柱形筒;内筒上端敞口;中筒下端敞口,倒扣在内筒外;中筒顶壁高于内筒上沿;中筒内设有与中筒同轴且共顶壁的芯筒;芯筒半径小于内筒半径;芯筒下沿高于内筒底壁;外筒套在中筒外;外筒内壁与中筒水平相对的位置处嵌有螺旋形延伸的螺旋盘管;螺旋盘管上均匀分布有向中筒外壁喷射的扁嘴喷头;外筒内腔于中筒上方设有雾化喷头;外筒底部设有水池;水池内液面低于中筒下沿;水池内的水通过循环水泵、水管与螺旋盘管、雾化喷头相连;外筒顶部设有出气口;外筒底部设有直通芯筒内的进气管。烟气自进气管进入芯筒内,再经芯筒下端进入内筒,经内筒上端进入中筒,经中筒下端进入外筒;烟气在迷宫式路径中进行降温和初步除尘。螺旋盘管和扁嘴喷头使得外筒与中筒之间形成多层螺旋形水膜,烟气进入外筒后自下而上穿过多层水膜,多数粉尘被螺旋形水膜截留除去;烟气经过螺旋形水膜后进入雾化喷头下方进行雾化除尘,将残余粉尘除去,洁净空气经出气口排放。烟气先后经过迷宫除 ...
