Background technology
After coal-burning power plant uses wet desulphurization, wet flue gas condenses in chimney and forms condensation acid solution, produces chimney
The strongest raw corrosivity, the commonly used spraying of domestic present stage, patch block and titanium alloy inner core etc., use acidproof
Brick is the most cracking, come off or acid solution seepage, uses titanium steel composite board or the sleeve of nickel-base alloy composite plate
The ruuning situation of formula chimney is good, but its cost is higher.
Meanwhile, under fiber glass reinforced plastic chimney working condition, wet flue gas is meeting and inner wall of stack under the conditions of certain gas speed
Produce electrostatic, thus cause the Soot accumulation in flue gas at inner wall of stack, increase surface roughness, to flow velocity
Producing impact, also can increase the load of chimney simultaneously, this can affect the normal use of chimney.
Summary of the invention
The present invention is directed to the problems referred to above, it is provided that a kind of smoke-gas wet desulfurization anticorrosion antistatic chimney, there is corrosion resistant
Lose performance more preferably, the advantages such as antistatic performance is good, and service life is longer, and cost is moderate, and the completion time of project is short.
The technical scheme is that a kind of smoke-gas wet desulfurization anticorrosion antistatic chimney, including chimney, its
It is characterised by: be provided with adhesive phase, stainless steel fibre and aramid fiber mixing Nomex, poly-at inner wall of stack
Sulfide fibers Nomex, inner wall of stack has in the middle of aramid fiber mixing Nomex one side with stainless steel fibre
Adhesive phase, stainless steel fibre and aramid fiber mixing Nomex another side with in polyphenylene sulfide fibre Nomex
Between have adhesive phase, be provided with anticorrosive coat at chimney outer wall.
Described stainless steel fibre is 7.5～8.0 millimeters with the thickness of aramid fiber mixing Nomex, grammes per square metre
3000g/m2。
The thickness of described polyphenylene sulfide fibre Nomex is 3.1～3.5 millimeters, grammes per square metre 1100g/m2。
The thickness of described adhesive phase is 1.9～2.0 millimeters.
The thickness of described anticorrosive coat is 2.5～3.0 millimeters.
The invention has the beneficial effects as follows: the present invention has decay resistance more preferably, antistatic performance is good, uses
The advantages such as the life-span is longer, and cost is moderate, and the completion time of project is short.
Compared with prior art, the invention have the advantages that, economic effect:
1) in inner liner, employing has the polyphenylene sulfide fibre of acid corrosion-resistant performance, and this fiber is resistant in flue gas
S02Concentration 5000～6000mg/Nm3, improve the acid corrosion-resistant performance of chimney；
2) stainless steel fibre that can conduct electricity, flue gas is used to produce quiet with equipment inner wall friction in inner liner fiber
During electricity, electrostatic is transmitted to connect electricity system by stainless steel fibre, and then eliminates electrostatic dust stratification, and service life is long；
3) by the spraying of chimney outer wall being had the quinary alloy powder of decay resistance, chimney corrosion resistance is improved.
