Abstract
The utility model discloses a kind of accurate distribution igniter of shock-wave ash blowing, including compressed air line, increase bypass duct all the way on compressed air line, be connected with turn：Stainless steel flexible hose, joint, bypass air magnetic valve and ball valve, stainless steel flexible hose is drawn after compressed-air filter, bypass air magnetic valve is in normally open, ball valve opens a part, when needing soot blowing, and supervisor's air solenoid valve is opened, bypass air closed electromagnetic valve, supervisor's air solenoid valve is closed after inlet period is arrived, and bypass air magnetic valve is opened, and is finally lighted a fire.The utility model improves compressed air piping on the original basis; add after purging pipeline; scavenging pipeline reduces backflow dust and clogged with soot when not lighting a fire; slow down the impact of reflux gas after igniting; protect valve body; the probability that each pipeline parts such as valve body are blocked or damaged can be greatly reduced, its service life is added, reduce frequency of maintenance and cost.
Description
Technical field
The utility model is applied to garbage incinerating power plant boiler superheater deashing process field, and specifically a kind of shock wave blows
The accurate distribution igniter of ash.
Background technology
Because the fuel of the boiler is house refuse, composition is more complicated, and the ash of flue gas is more after burning, molten condition
Flying dust is wrapped on superheater tube outer wall, and the heat transfer efficiency of superheater will be reduced, and not clear up easily cause superheater blocking for a long time,
So as to influence boiler combustion.
Existing garbage incinerating power plant boiler superheater deashing major way has：Zheng vapour Chui Hui ﹑ Ji ripple Chui Hui ﹑ vibration dust-cleanings three
Kind；Steam soot blowing occupation area of equipment is big, and maintenance is larger, and soot blowing has dead angle, and vibration dust-cleaning effect is poor, and rapping position
It is easily broken off；So garbage incinerating power plant superheater deashing is mainly the mode of shock-wave ash blowing now, distribution igniter is
The core component of shock-wave ash blowing, it act as：Fuel gas is uniformly mixed by a certain percentage with compressed air, pipeline is set back
Fiery device and air purge set, high-energy igniter light mixed gas, reach blast in surge tank, the shock wave of generation and
Strong sound wave acts on superheater surface by spout, by repeatedly repeatedly acting on dust stratification surface, even harder
Matter black dirt, also can eventually fall out its pine that shakes.
The shock-wave ash blowing distribution igniter used in the prior art, assembles scattered, no air purge set, is also easy to produce quick-fried
Fried shock wave backflow situation, causes acetylene tempering valve to block, and easy damaged magnetic valve causes magnetic valve adhesive not in place.The opposing party
Face original using shock-wave ash blowing acetylene and air stoichiometry in terms of it is chaotic, situation appearance or not when ringing sometimes.
Utility model content
In order to solve above-mentioned technical problem present in prior art, the utility model is empty in the compression of original pipeline foundation
Increase bypass duct all the way on air pipe, concrete technical scheme is as follows：
A kind of accurate distribution igniter of shock-wave ash blowing, including compressed air line, increase on compressed air line
Bypass duct, is connected with turn all the way：Stainless steel flexible hose, joint, bypass air magnetic valve and ball valve, stainless steel flexible hose is in compression
Drawn after air cleaner, bypass air magnetic valve is in normally open, and ball valve opens a part, when needing soot blowing, supervisor
Air solenoid valve is opened, bypass air closed electromagnetic valve, and supervisor's air solenoid valve is closed after inlet period is arrived, bypass air electromagnetism
Valve is opened, and is finally lighted a fire.
The utility model improves compressed air piping on the original basis, adds after purging pipeline, is purged when not lighting a fire
Pipeline reduces backflow dust and clogged with soot, slows down the impact of reflux gas after igniting, protects valve body, can greatly reduce valve body
The probability for blocking or damaging etc. each pipeline parts, adds its service life, reduces frequency of maintenance and cost.
Brief description of the drawings
Fig. 1 is the accurate distribution ignition device structure schematic diagram of shock-wave ash blowing of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, the accurate distribution igniter of shock-wave ash blowing of the present utility model, including compressed air line 5,
Increase bypass duct all the way on original compressed air line, including：Stainless steel flexible hose 1, joint 2, the and of bypass air magnetic valve 3
Ball valve 4, adds a bypass after compressed-air filter, and bypass air magnetic valve 3 is in normally open, and ball valve 4 is opened
A part, has been achieved in that the function of bypass purging, when needing soot blowing, and supervisor's air solenoid valve 6 is opened, bypass air electromagnetism
Valve 3 is closed, and inlet period is responsible for air solenoid valve 6 after and closed, and bypass air magnetic valve 3 is opened, and is finally lighted a fire, time of generation
Gas is known from experience the compressed air being bypassed and slowed down, so as to play the function of protecting each valve body.
On the other hand, it is that compressed air pressure exists mixed gas repeatedly accurately to be matched by us to test obtained conclusion
0.3Mpa, acetylene pressure explosive effect in 0.15Mpa is best, and can succeed every time, and inflationtime is according to live distributing cabinet
To depending on the distance of surge tank.
