Abstract

一种烟道阀门包括进烟管道、插板、差压圈和排烟管道,进烟管道一端与引风机进出口连接,排烟管道一端与排烟筒连接,差压圈安装在插板后。本实用新型的有益效果在于:当引风机停用时,烟道阀门落下,为防止潮湿烟气透过烟道阀与烟道间缝隙进入引风机,导致引风机带水腐蚀,在插板阀后侧加差压圈,并通过管道将空气送入差压圈,以阻止烟气进入引风机。

Description

一种烟道阀门
技术领域
本实用新型涉及一种烟道阀门,尤其涉及一种废气处理领域的脱硫装置。 
背景技术
目前锅炉等排出的烟气大多需要经过脱硫除尘后方可排放到大气中。由于一个锅炉房内常常有多套脱硫装置,但只能共用一个排烟筒,当多套脱硫装置中有脱硫装置停用时,就会使运行的脱硫装置排出的烟气回流到停用的引风机、脱硫塔及其他设施内,从而造成腐蚀,甚至带来操作人员的安全问题。 
实用新型内容
本实用新型所要解决的技术问题是提供一种结构合理且能阻止烟气回流的烟道阀门。 
一种烟道阀门包括进烟管道、插板、差压圈和排烟管道,进烟管道一端与引风机进出口连接,排烟管道一端与排烟筒连接,差压圈安装在插板后。 
优选地,所述的烟道阀门包括差压圈以及依次相连的阀杆驱动、阀杆和位于阀体内的插板。 
优选地,所述的差压圈上有一个外部气源接口。 
优选地,所述的插板两侧设有密封板的限位装置。 
本实用新型的有益效果在于: 
1.  当引风机停用时,烟道阀门落下,为防止潮湿烟气透过烟道阀与烟道间缝隙进入引风机,导致引风机带水腐蚀,在插板阀后侧加差压圈,并通过管道将空气送入差压圈,以阻止烟气进入引风机。
2.  插板阀后侧设有差压圈,插板阀包括差压圈及依次相连的阀杆驱动、阀杆和位于阀体内的插板,插板两侧设有限位装置,中空阀体内侧设有密封板的限位装置,通过管道将空气送入差压圈外部气源进口,使烟道阀门结构更为合理,阻烟效果更好。 
附图说明
图1为本实用新型结构示意图。 
具体实施方式
下面结合附图和实施例进一步详细说明本实用新型,但本实用新型的保护范围并不限于此。 
如图1所示,一种烟道阀门包括气源进口1、差压圈2和排烟管道3、插板4、进烟管道5、引风机6、转盘7和螺杆8,气源进口1与差压圈2连接,排烟管道3和进烟管道5间安装插板4,差压圈2安装在插板后侧且底部与排烟管道3焊接,插板4、螺杆8及转盘7连接在成一体,转盘7转动可带动螺杆8将插板4拉起或放下,为防止插板晃动,在插板两侧安装有限位装置。 

Claims (4)
