This is one and adopts local raw material, the improvement invention of manufacture of intraocular synthesis of dichroite based high temperature ceramic heat-exchanger.It is bond that the present invention adopts cheap water soluble organic substance solution, through rolling the film roller press briquetting, makes the bonding slip with this blank, adopts and loads firing technology, makes the crossed cordierite based high temperature ceramic heat-exchanger of the sine wave with different sizes.
As everyone knows, when making high temperature ceramic heat-exchanger with cordierite, the external raw materials such as expensive magnesite, talcum, aluminium oxide that adopt mostly.
The thermoplastic organic polymer that the plasticising bond adopts China to lack mostly is a bond.It is major ingredient that the present invention adopts region flint clay, mild-clay, artificial synthesis of dichroite base pottery.
Adopting the water-soluble organic polymer of the abundant cheapness of China's output is bond, has made qualified right-angled intersection thin wall cordierite based high temperature ceramic heat-exchanger.
When becoming overall structure by the layering monomeric adhesion, the present invention adopts this blank slurry to make bond, has guaranteed the globality of the high temperature ceramic heat-exchanger after the burning and has had good anti-chilling hot property.
Characteristics at the plasticising bond, adopt and load firing technology, thereby guaranteed that product has lower leak rate, whole good, profile rule just, overcome and weakened because of adjacent corrugated plate and plain film are in the right-angled intersection position, the bursting stress that causes during contraction has improved the burning yield rate of product greatly.
Detailed description of the present invention:
The present invention has introduced the improvement of right-angled intersection thin wall cordierite based high temperature ceramic heat-exchanger.
The conventional method that is used to make right-angled intersection thin-walled high temperature ceramic heat-exchanger has, and at first ceramic powder and thermoplastic binder is mixed, through rolling film, cutting, roll-in, bonding, process, firing and form.Big with the equipment investment of said method manufacturing ceramic heat exchanger, the manufacturing cost height.
The invention provides a kind of raw material sources inexpensive method of manufacturing widely.The characteristics of this method be with burn jewel, green coke jewel, burn talcum earlier through in broken, again with burn aluminium oxide, the levigate mill of mild-clay goal, cross 10000-hole sieve, that powder is beaten in oven dry is standby.
With above-mentioned standby powder is 100 parts, water-soluble organic polymer soln is 40 parts, make the thin slice of 0.2～0.8 millimeters thick through rolling film, after the cutting, a part of plain film is sent to drying, and a part of plain film is sent to the sinusoidal wave corrugated plate that different moduluses are made in roll-in, with this blank slurry a slice corrugated plate and a slice plain film are bonded together and form unit (Fig. 1 a, b), after the oven dry, by the right-angled intersection position that above-mentioned monomer is bonding once more, form overall structure (Fig. 2).
With above-mentioned bulk ceramics heat exchanger semi-finished product oven dry, through being machined to required size, burn product with alumina hollow ball filling technology dress, burnt to 13701370 ℃ ± 20 ℃ insulations 2～4 hours through 42～56 hours, ceramic heat exchanger after burned is through cleaning, block with the part of high-temperature inorganic adhesive, can deliver assembling after qualified through leaking hunting and use obstructed gas.
The invention process 1:
To burn jewel, green coke jewel, to burn talc lump broken in jaw crusher respectively, batching is promptly burnt jewel 20～40% by weight percentage then, green coke jewel 20～30% burns talcum 15～30%, burns aluminium oxide 10～20%, mild-clay 10～15%.Add grinding in ball grinder after the weighing, cross 10000-hole sieve, dry, beat powder, it is standby to cross 40 mesh sieves.With above-mentioned getting the raw materials ready is 100 to add polyvinyl alcohol water solution 40% especially, is rolled to 0.5 millimeter, is cut into 230 * 370 millimeters and 230 * 250 millimeters plain films, after the oven dry, wherein partly is pressed into the ripple of the sine wave of different moduluses through pair roller; Oven dry, being bonded to monomer with this blank slurry dries again, use above-mentioned monomer (Fig. 1 again, a, b) be bonded to whole shape ceramic heat exchanger by the right-angled intersection position, drying, be processed into 208 * 208 * 336 millimeters semi-finished product after pouring into the hot melt organic matter, load with the hollow garden of aluminium oxide ball and burn till caulking joint, technical process such as leak hunting makes the exhaust gases passes right-angled intersection thin wall cordierite based high temperature ceramic heat-exchanger identical with air duct bellows-shaped size.The chemical analysis of its goods is SiO
240～55%, Al
2O
330～40%, MgO5～12%, Fe
2O
30.4～0.7%, KNa0.5～0.9%.
The invention process 2:
To burn jewel, green coke jewel, to burn talc lump broken in jaw crusher respectively, then by burning jewel 15～35%, green coke jewel 10～30%, burn talcum 15～35%, aluminium hydroxide 10～20% burns aluminium oxide 0～10%, mild-clay 10～20%, following operation is identical with enforcement 1.But the ripple size of the alternate passage of right-angled intersection is inequality, and exhaust gases passes is bigger than air duct, and appearance and size is 380 * 247 * 215 millimeters right-angled intersection thin wall cordierite based high temperature ceramic heat-exchanger.Its goods chemical analysis is with implementing 1.
Crossed cordierite based high temperature ceramic heat-exchanger, it is supporting to can be used for each class A furnace A or gas-turbine, reclaims the heat of 900～1100 ℃ flue gas, and temperature efficiency is about 50%, and leak rate is below 10%. Use ceramic heat exchanger provided by the invention can save the fuel consumption of industrial furnace and energy rotary device, energy-saving efficiency is about 30%.
