Background technology
After coal-burning power plant uses wet desulphurization, wet flue gas condenses in equipment and forms condensation acid solution, produces equipment
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 equipment is good, but its cost is higher.
Summary of the invention
The present invention is directed to the problems referred to above, it is provided that the corrosion-proof lining of a kind of smoke-gas wet desulfurization equipment, there is corrosion resistant
Lose performance more preferably, the advantages such as fire resistance is good, and service life is longer, and cost is moderate, and the completion time of project is short.
The technical scheme is that the corrosion-proof lining of a kind of smoke-gas wet desulfurization equipment, including adhesive phase,
Stainless steel fibre Nomex, aramid fiber Nomex, polyphenylene sulfide fibre Nomex, it is characterised in that:
Described stainless steel fibre Nomex has adhesive phase, at described aramid fiber with the centre of aramid fiber Nomex
Nomex has adhesive phase, the lower surface of stainless steel fibre Nomex with the centre of polyphenylene sulfide fibre Nomex
There is adhesive phase.
The thickness of described stainless steel fibre Nomex is 5.5～6.5 millimeters, grammes per square metre 2000g/m2。
The thickness of described aramid fiber Nomex is 1.9～2.2 millimeters, grammes per square metre 600g/m2。
The thickness of described polyphenylene sulfide fibre Nomex is 2.8～2.9 millimeters, grammes per square metre 900g/m2。
The thickness of described adhesive phase is 1.5～1.8 millimeters.
The invention has the beneficial effects as follows: the present invention has decay resistance more preferably, fire resistance is good, uses the longevity
Order longer, the advantages such as 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 resistance to strong acid corrosion, and this fiber is resistant in flue gas
SO2Concentration is 5000～6000mg/Nm3Corrosive gas, improve the acid corrosion-resistant performance of equipment；
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) in inner liner fiber, employing has the aramid fiber of fire resistance, improves the fire resistance of equipment.
