    Calcium Carbonate Paddle Dryer Contra Flow Low Temperature Dryer

    Contra-Flow Low Temperature Paddle Dryer for Drying Calcium Carbonate in Transmission

    Product Description

    Product Description

    Product Introduction

    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.
    Working principle

    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.
    Performence characteristics

    Performance characteristics

    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.
