A kind of preparation method of novel silicon titanium membrane tube
Technical field
The present invention relates to silicon titanium membrane tube production technical field, specially a kind of preparation method of novel silicon titanium membrane tube.
Background technique
Although silicon titanium membrane tube service life currently on the market is higher by much than common tube, air preheater low-temperature zone The main reason for windward side 400mm seriously corroded, sub other positions variation of whole root canal is little, this situation is air preheater low temperature knot Dew is serious, and very big to damaging inside and outside pipe cold wind end entrance pipe, silicon titanium film has very strong corrosion resistance, if blindly It all thickeies silicon titanium film thickness or inside and outside silicon titanium film process of doing entirely is undoubtedly the effective ways for solving low-temperature corrosion, but Cost can be multiplied, and increase very big financial burden for a user, be also one for other positions sub for whole root canal The unnecessary waste of kind, in addition, the generation of ash is blocked up in air preheater, mainly since the sulfuric acid vapor in flue gas condenses in On heating surface, generate caused by low-temperature corrosion.On metal heated face, be deposited on sulfuric acid solution dissolution tube wall on oxidation film (Fe3SO4) and metal (Fe), it is easy to react with flying dust, to generate acid bonding ash.Acidity bonding ash composition foot: Al2 (SO4)3、CaSO4And FeSO4、Fe(SO4)3.As the SO in flue gas3Concentration is in 5uL/L. or more, the low temperature of air preheater Corrosion will be the most serious, while also form more acid bonding ash.In addition, being removed in the smoke inlet section of air preheater The bonding of acid bonding ash and corrosion are outer, can also be by out of furnace and superheater area bring is sintered grey fragment and slag particle institute Blocking, influences the normal operation of air preheater.If soot blower leakage or economizer rupture leak, ash can become wet Profit, bonds agglomerating under surface tension effects, blocks so as to cause air preheater.Therefore, to make boiler and air preheater Safe and reliable operation, it is necessary to take effective measures, reduce dust stratification and corrosion is needed for such situation in original silicon titanium It is improved on the basis of golden film pipe, to meet the needs of market.
Summary of the invention
To solve the above-mentioned problems, the purpose of the present invention is to provide a kind of preparation methods of novel silicon titanium membrane tube.
To achieve the above object, the invention provides the following technical scheme: a kind of preparation method of novel silicon titanium membrane tube, Steps are as follows:

E, soaked silicon titanium membrane tube is put into drying box, carries out 230 ° of dehumidifying drying processing in 2 hours；
F, it is put into production line to be fired, speed 10-30cm per minute；
G, it fires and completes to be cooled down into four 16 outlet system of air of air inlet；
H, finished product off-line test.
Preferably, coating film thickness, it is 300 μm ± 20 μm of single layer, 600 μm ± 50 μm double-deck.
Preferably, silicon titanium membrane tube curvature≤2mm/m, total curvature is no more than 5mm/ root, silicon titanium membrane tube nozzle Ovality≤0.5mm, length variation≤0.5mm.
Preferably, the Tio of 12-15% is provided in silicon titanium film powder raw material2, 1~5% NiO2And 50~60% SiO2
Compared with prior art, the beneficial effects of the present invention are: the preparation method of the novel silicon titanium membrane tube；
1, it joined the Tio of 12-15%2, it is anti-oxidant when making its high temperature, have high abrasion acid-alkali-corrosive-resisting；
2, it joined 1~5% NiO2Keep its surface moist, be not easy dust, sufficiently solves the problems, such as stifled ash；
3, add 50~60% SiO2Make Rockwell hardness HRC > 60 kilogram, solve flue gas wear problem, heat exchange can be made to imitate Fruit is more preferable, is heated to 1000 DEG C or more, quick refrigeration again sharply heating will not fragmentation, service life can extend 5 times or more；
4, the defects of fast for air inlet corrosion on the basis of original silicon titanium membrane tube, plates one layer of silicon titanium using inner wall 40CM In addition golden film plates one layer of silicon titanium film in outer wall 40CM again, one layer of inner membrance, double-layer outer membrane are formed in the 40CM of end to be formed, It compares to have without inner membrance light single layer outer membrane originally after testing and improves very big step in corrosion-resistant, wear-resistant degree.This I.e. solve low-temperature corrosion is effectively saved cost to the harm of pipe to kind technique again, reduces unnecessary waste, this is novel Silicon titanium membrane tube substantially prolongs the service life of silicon titanium membrane tube and reduces maintenance cycle etc., to can bring to user Bigger economic benefit.
