Abstract
The soot blower in a kind of SCR reactors is the utility model is related to, the device opens a hole on the side of SCR reactors and catalyst position and installs blowing pipe mounting flange；The blowing pipe of nozzle is provided with the side that blowing pipe mounting flange is located in SCR reactors, blowing pipe is connected with blowing pipe rolling wheel support, and is movably arranged on by high temperature resistant roller on blowing pipe rolling wheel support；Gas bag and impulse electromagnetic valve are installed on the side that blowing pipe mounting flange is located at outside SCR reactors.Using the utility model, in medium and small boiler denitration transformation project, effective soot blowing effect is reached in the small space that can be installed in SCR reactors, and in the case of not blowing out, the adjustment for blow back pipe nozzle is changed, and saves the time.
Description
Art
The soot blower in a kind of SCR reactors is the utility model is related to, is mainly used in medium and small boiler denitration transformation project,
SCR reactors are added between economizer and air preheater, can solve the problems, such as soot blowing using this device.
Background technology
As the requirement of national environmental protection discharge improves, medium and small boiler is also required to carry out denitration transformation, will to reach NOx emission
Ask.Medium and small boiler denitration transformation project, carry out adding SCR reactors between economizer and air preheater, due to empty in reactor
Between it is narrow and small, catalyst installation after space it is limited, in general acoustic wave ash ejector and steam sootblower do not have suitable installation site, lead
Cause can not be satisfactory to both parties.
The content of the invention
The purpose of this utility model is arranged in small space, can be reached effective soot blowing effect, can also not stopped
In the case of stove, the soot blower in a kind of SCR reactors for the adjustment replacing for blow back pipe nozzle.
The utility model adopts the technical scheme that：Soot blower in a kind of SCR reactors, it is characterised in that in SCR
A hole is opened on the side of reactor and catalyst position and blowing pipe mounting flange is installed；Blowing pipe mounting flange is located at
The blowing pipe of nozzle is provided with side in SCR reactors, blowing pipe is connected with blowing pipe rolling wheel support, and by resistance to
High temperature roller is movably arranged on blowing pipe rolling wheel support；Installed on the side that blowing pipe mounting flange is located at outside SCR reactors
There are gas bag and impulse electromagnetic valve.
Using the utility model, in medium and small boiler denitration transformation project, can be installed in narrow in SCR reactors
Reach effective soot blowing effect in small space, and in the case of not blowing out, the adjustment for blow back pipe nozzle is changed, during saving
Between.
Brief description of the drawings
Fig. 1 is application schematic diagram of the present utility model.
Fig. 2 is the connection diagram of blowing pipe of the present utility model and blowing pipe rolling wheel support.
Sequence number represents in figure：Blowing pipe 1, blowing pipe rolling wheel support 2, blowing pipe mounting flange 3, nozzle 4, elbow connection method
Orchid 5, elbow 6, Thermostable flexible hose 7, gas bag 8, impulse electromagnetic valve 9, high temperature resistant roller 10, anchor ear 11, SCR reactors 12 and catalysis
Agent 13.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Figures 1 and 2, the soot blower in the SCR reactors is in the side of SCR reactors 12 and catalyst 13
Position on open a hole and blowing pipe mounting flange 3 be installed；Blowing pipe mounting flange 3 is located in SCR reactors 12
The blowing pipe 1 of nozzle 4 is provided with side, is connected between blowing pipe 1 and blowing pipe rolling wheel support 2 by anchor ear 11, and
It is movably arranged on by high temperature resistant roller 10 on blowing pipe rolling wheel support 2；The mounting flange of blowing pipe 3 is located at outside SCR reactors 12
Side on by pacifying elbow 6 and Thermostable flexible hose 7 gas bag 8 and impulse electromagnetic valve 9 are installed.
In use, the certain interval of time of impulse electromagnetic valve 9 carries out deashing to catalyst 13 under control program control, it is removable
The nozzle 4 unloaded is online as needed to be changed, and when changing nozzle 4, only need to pull down elbow 6 and adpting flange 5 and Thermostable flexible hose
7, pull out blowing pipe 1, blowing pipe 1 by high temperature resistant roller 10 from blowing pipe rolling wheel support 2 it is protruding, pull down anchor ear afterwards
11, you can carry out nozzle 4 and change.
