The special wedge-type stirring heat transfer paddle in the device has high heat transfer efficiency and self-cleaning function of the heat transfer surface. Refinery sludge dryer can indirectly heat or cool the paste, granular, powder, and slurries. It can perform such operations as drying, cooling, heating, sterilization, reaction, and low-temperature combustion.
Refinery Sludge Dryer Working principle
Hollow shafts are densely arranged with wedge-shaped hollow blades,
and the hot medium flows through the hollow shaft through the
hollow shaft. There is a large area of heat transfer within
the unit's effective volume. The temperature of the heat medium
ranges from -40°C to 320°C. It can be water vapor or liquid type:
Such as hot water, heat transfer oil, etc. Indirect conductive
heating, without carrying air to take away heat, heat is used to
heat the material. The heat loss is only through the body heat
insulation layer to the environment. The wedge blade heat transfer
surface has a self-cleaning function. The relative motion of
the material particles and the wedge-shaped surface creates
a scrubbing action that can wash away the adhered material on
the wedge surface so that a clean heat transfer surface is
maintained during operation. The shell of the paddle dryer is
Ω type, and two to four hollow stirring shafts are generally
arranged in the casing. The housing has a sealed end cap and
a top cover to prevent material dust from leaking out and
fully functioning.
The heat transfer medium passes through the rotary joint and flows
through the housing jacket and the hollow agitation shaft. The
hollow agitation shaft has different internal structures according
to the type of the heat medium to ensure the best heat transfer
effect.
Blade dryer energy consumption is low: As a result of indirect
heating, there is not a lot of carrying air to take away heat,
and the outer wall of the dryer is provided with insulation layer.
For slurry materials, only 1 kg of water vapor is needed to
evaporate 1 kg of water.
Low cost of blade dryer system: The unit has a large heat
transfer surface in the effective volume, which shortens the
processing time and reduces the size of the equipment. It has
greatly reduced the construction area and the construction
space.
Wide range of processing materials: With different heat media,
heat-sensitive materials can be processed and materials that
require high temperature treatment can be processed. Commonly used
media are: Water vapor, thermal oil, hot water, cooling water and
so on.
Both continuous and intermittent operation can be applied in many
fields.
Low environmental pollution: Do not use carrying air, dust material
is very little entrainment. The solvent evaporation volume is very
small and it is easy to handle.
Closed-circuit circulation may be used for contaminated materials
or conditions where solvent is to be recovered.
Operating cost is low: The structure. The amount of wear is small
and maintenance costs are low.
Operation stability: Due to the special compression-expansion
stirring action of the wedge-shaped paddle, the particles of the
material are fully in contact with the heat transfer surface. In
the axial range, the gradient of temperature, humidity and mixing
degree of the material is very small, thus ensuring the process
Stability.
Adaptable material
Paddle dryer has been successfully used in food, chemical,
petrochemical, dye, industrial sludge and other fields. The heat
transfer, cooling, and stirring characteristics of the equipment
allow it to perform the following unit operations: Combustion (low
temperature), cooling, drying (solvent recovery), heating
(melting), reaction, and sterilization. The stirring blade is
a heat transfer surface at the same time, so that the heat
transfer area in the effective volume per unit is increased, and
the processing time is shortened. The wedge-shaped blade heat
transfer surface also has a self-cleaning function.
Compression-expanding stirring function makes the materials mixed
evenly. The material moves in the axial direction as "plug flow".
In the axial interval, the gradient of temperature, humidity and
mixing degree of the material is very small. The heat medium blade
dryer can be used for the low-temperature combustion work. Such as:
Calcium sulfate dihydrate (Ca2SO4 · 2H2O) combustion into
calcium sulfate hemihydrate (Ca2SO4 · 1/22H2O). Sodium
bicarbonate (NaHCO3) was converted into soda (Na2HCO3) by
calcination. The cooling medium, such as water, cooling brine,
etc., can be used for cooling. For example, paddle coolers used in
the soda industry replace old-fashioned air-cooled coolers, saving
energy and exhaust gas treatment equipment, and lowering operating
costs. Drying, the most important function of the equipment, does
not use hot air, so that solvent recovery, energy consumption, and
environmental control are in an ideal state of easy handling.
Particularly suitable for the recovery of solvents, flammable and
easily oxidized heat-sensitive materials. Has been widely used in
fine chemicals, petrochemicals, dyes industry. Within the axial
section, the uniformity of temperature, humidity, and mixing allows
the device to be used for heating or melting, or for some solid
material reaction. It has been successfully used in the compound
fertilizer and modified starch industries. The paddle dryer can be
used to sterilize food and flour. The large heating area in the
unit's effective volume quickly heats the material to the
sterilization temperature, avoiding long-term heating and changing
the material quality.
