Product description
Printing and dyeing sludge dryer
By absorbing foreign advanced technology, based on to improve and optimize the
design of the wedge-shaped hollow paddle dryer for paste, granular, powder,
paste material indirect heating or cooling , to be completed by drying, cooling,
heating, sterilization, reaction, low temperature calcination and other unit
operations. Wedge-shaped mixing device in a special heat transfer blade, has a
high heat transfer efficiency and heat transfer surface self-cleaning
function.
Large - scale printing and dyeing sludge dryer:
Densely
lined with wedge-shaped hollow shaft hollow blades, heat medium through the
hollow axial flow through blades. Unit effective volume of a very large area of
heat transfer, heat medium temperature from -40 ℃ to 320 ℃, can be water vapor,
may also be liquid-type: such as water, oil and so on. Indirect conduction
heating, the air does not carry away the heat, the heat are used to heat
materials. Only through the device body heat loss to the environment, heat
insulation layer. Wedge-shaped blades with self-cleaning heat transfer surfaces.
Wedge-shaped surface material particles and scrubbing effect relative movement,
to wash away the wedge surface material attachments, so in operation have
maintained a clean heat transfer surfaces. Blade dryer for the W-type shell, the
shell of the general arrangements for 2-4 hollow stirring shaft. Shell with a
sealed cover with the cover to prevent dust leakage and collection of materials,
solvent vapor materials. Set out and exit pull a block, to ensure a high degree
of material level, so that heat transfer surface is covered with full play
materials. Heat medium through the rotary joint, passing through the shell
jacket and the hollow stirring shaft, hollow shaft stirring according to the
type of thermal media have different internal structures to ensure the best heat
transfer.
Low energy consumption printing and dyeing sludge dryer:
Blade
dryer has been successfully used in food, chemical, petrochemical, dye,
industrial sludge and other fields. Equipment heat, cooling, mixing features
make it to complete the following unit operations: calcination (low
temperature), cooling, drying (solvent recovery), heating (melting), response
and sterilization. Mixing blades at the same time the heat transfer surface, the
effective volume per unit area of heat transfer increases, reducing the
processing time. Heat transfer surfaces in wedge-shaped blades with
self-cleaning function. Compression - Expansion mixing features make the
material mixed uniformly. Material along the axis into a "plug flow" movement,
in the axial zone, the material temperature, humidity, mixing a very small
degree of gradient.
●
Conducting oil to do with the heat medium, blade dryer to complete the work of
low-temperature calcination. Such as: calcium sulfate dihydrate (Ca2SO4 · 2H2O)
calcined into calcium sulfate hemihydrate (Ca2SO4 · 1/2H2O). Sodium bicarbonate
(NaHCO3) into calcined soda (Na2CO3) and so on.
●
Pass into the cooling medium, such as water, salt, etc. can be used to cool the
cooling. Such as: use of soda ash industry in blade-type cooler base machine to
replace the old air-cooled cooler base machine, saving energy and exhaust gas
processing equipment, lower operating costs, but also for titanium, nickel alloy
powder and all kinds of powder granular materials cooling. On a single machine
where the material can be cooled from 1000 ℃ to less than 40 ℃.
●
Dry, the main function of equipment, do not use hot air to solvent recovery,
energy consumption, environmental control is easy to deal with the ideal state.
On the need to recover solvents, heat-sensitive materials, particularly
flammable adapt easily oxidized. Has been widely used in fine chemical,
petrochemical, dye industry.
●
Axial range, temperature, humidity, mixing degree of uniformity, so equipment
can be used to heating or melting, or some solid material response. In the
compound and modified starch industries have been successfully used. Blade dryer
can be used to carry out sterilization of food and flour. Unit within the
effective volume of a large heating area, will soon be material heated to
sterilization temperature, to avoid prolonged heating change the quality of
materials.
Adaptation
of materials
Petrochemical Industry: polyolefin powder, polycarbonate resin, high and low
density polyethylene, linear low density polyethylene, polyacetal particles,
nylon 6, nylon 66, nylon 12, cellulose acetate, polyphenylene sulfide, propylene
base resin, engineering plastics, polyvinyl chloride, polyvinyl alcohol,
polystyrene, polypropylene, polyester, polyoxymethylene, styrene ~
Acrylonitrile, ethylene propylene copolymer ~.
Environmental protection industry: PTA sludge, electroplating sludge into the
water, boiler ash, pharmaceutical waste, sugar residue, glutamate factory waste,
coal ash.

pharmaceuticals.
Chemical industry: soda ash, NPK fertilizer, kaolin, bentonite, white carbon
black, carbon black, phosphorus gypsum, oxidation of sodium fluoride, calcium
nitrate, magnesium carbonate, sodium cyanide, aluminum hydroxide, barium
sulfate, sulfuric acid , calcium carbonate, dyes, molecular sieve,
saponin.
Printing and dyeing sludge special dryer:
●
Blade dryer energy consumption is low: as indirect heating, the air does not
carry away a lot of heat insulation of dryer wall has, on the slurry material,
evaporation of 1kg of water vapor only 1.22kg.
●
Blade dryer system costs low: within the effective volume of units have a large
heat transfer surface, the reduced processing time, equipment size becomes
smaller. Would greatly reduce the building area and building space.
●
Dealing with a wide range of materials: using a different hot medium, able to
deal with heat-sensitive materials can be heat-treated materials handling.
Commonly used media are: water, steam, oil, hot water, cooling water. Continuous
operation can also be intermittent operation can be applied in many fields.
●
Environmental pollution: do not carry air, dust entrainment few materials.
Solvent evaporation material is very small, easy to handle. To have contaminated
materials or be recycled solvent conditions, can be used closed circuit.
●
Low operating cost: the equipment normal operation, only 1 hour / Heaven. Low
speed and reasonable structure. Wear a small, very low maintenance costs.
●
Operation stability: As the wedge-shaped blades of special compression -
expansion of stirring, so that material particles sufficient surface contact
with the heat transfer in the axial zone, the material temperature, humidity,
mixed density gradient is very small, thus ensuring the process
stability.
