Description
Technical field
This utility model relates to a kind of chimney positive pressure protection analog and method, particularly relates to a kind of Wet chimney malleation and protects
Protect analog.
Background technology
The effect of chimney be by fuel combustion after flue gas be delivered in the air of certain altitude discharge, chimney structure is main
Including urceolus and inner core.Urceolus is mainly poured by armored concrete and forms, and primarily serves stress load-bearing effect.Inner core is the most resistance to
Brick inner core and integral plate that acid refractory brick etc. is built into weld the steel inner cylinder two kinds tied, and acting primarily as smoke evacuation insulation, isolating flue gas, it is to avoid
The effect of flue gas corrosion urceolus.
Along with Environmental Protection in China regulation increasingly stringent, current operating unit is the most supporting to be taken off with Gypsum Wet
Sulfur technique is main flue gas desulfurization device.Owing to humidity increase, the temperature of flue gas after desulfurization decline, and desulfurizer is to three oxidations
The removal efficiency of sulfur is relatively low, therefore, flue gas easily in chimney condensation form acid condensed fluid, than non-desulfurization time flue gas more corrode
Property.
Wet chimney is many with operation under positive pressure, and due to the reason of malleation, wet flue gas is to inner wall of stack tympanites, diffusion, penetrating power
Strengthening, the corrosion to chimney aggravates.When especially having the defects such as crack when chimney lining, condensed fluid can penetrate into whole liner and cylinder
Body, causes corrosion to be accelerated, jeopardizes safety in production.
If the method for operation of chimney can become negative pressure run, then it is avoided that the infiltration at inner wall of stack of the flue gas condensing liquid,
Thus effectively stop the corrosion of chimney.
Summary of the invention
In order to solve above-mentioned deficiency, the purpose of this utility model be to provide a kind of Wet chimney positive pressure protection analog and
Method, the sleeve-type chimney that positive-pressure type is run, in the case of considering that inner/outer tube has leakage, take to chimney interlayer air blast
Mode, improves and maintains interlayer pressure, make interlayer pressure higher than chimney internal cylinder operating pressure, with reach to stop flue gas condensing liquid to
Inner wall of stack permeates, thus reaches to suppress the purpose of chimney internal cylinder wall erosion.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
A kind of Wet chimney positive pressure protection analog, is mainly formed Wet chimney model, described urceolus 6 by inner core 5 and urceolus 6
On have air inlet 7, relief valve 1 and discharge outlet 9, air inlet 7 connecting fan 10；Simulated field cigarette is had on described inner core 5 sidewall
Multiple defective hole 3 of chimney defect, the stopple 4 of blocking defective hole 3, have one or more leakage hole 8 bottom inner core 5；In connecting
It is connected to Pressure gauge 2 on the composition surface of cylinder 5 and urceolus 6.
Described relief valve 1 is positioned at urceolus 6 upper position, uses for adjusting means pressure.
Described discharge outlet 9 is positioned at bottom urceolus 6, and emission testing waste water is used.
Described stopple 4 has solid and hollow two kinds, and hollow stopple has the aperture of different pore size.
Described blower fan 10 is centrifugal blower, and total head is 800kPa-2000kPa, from air inlet 7 to device air blast.
Described Pressure gauge 2 is capsule pressure gauge.
Described inner core 5 and urceolus 6 are column type straight tube, and material is lucite.
The analogy method of a kind of Wet chimney positive pressure protection analog described above, urceolus 6 and inner core 5 form Wet chimney
Model, opens some defective hole 3, simulation chimney outer wall or the leakage situation of inwall, adjusts the aperture of relief valve 1, by entering
Air port 7 air blast also maintains constant blast, makes urceolus 6 and inner core 5 interlayer pressure higher than chimney internal cylinder operating pressure；Push up from inner core 5
The slow water filling in portion, observes the reading of moment Pressure gauge 2 before inner core bottom leakage mouth 8 has water to leak；I.e. simulate certain Wet chimney
Blast needed for positive pressure protection.
The most relatively, this utility model possesses following advantage:
This utility model can simulate various chimney defect, the different defects of correspondence, it is provided that the pressure needed for positive pressure protection, just
The method of pressure protection has small investment, environmental protection, flexible operation compared to anti-corrosion modes such as anticorrosion with coat, corrosion resistant alloy material chimneys
Etc. advantage.
Accompanying drawing explanation
Fig. 1 is this utility model Wet chimney positive pressure protection analog structural representation.
Detailed description of the invention
With detailed description of the invention, structural principle of the present utility model and operation principle are made the most below in conjunction with the accompanying drawings
Describe in detail bright.
As described in Figure 1, this utility model one Wet chimney positive pressure protection analog includes: inner core 5 and urceolus 6 are by flange
It is formed by connecting, forms chimney model, described urceolus 6 has air inlet 7, relief valve 1 and discharge outlet 9, air inlet 7 connecting fan
10；The defective hole of inner core side opening 3, the defect such as simulated field chimney cracks.Open blower fan 10, adjust relief valve 1 aperture, make dress
Put and maintain a certain pressure, inner core top slowly pour water to device, observe the peak level that can maintain under this pressure, in observing
Cylinder bottom leakage mouth 8 has the reading of moment Pressure gauge 2 before water leakage；I.e. simulate the wind needed for certain Wet chimney positive pressure protection
