Introduction
The dryer is an indirect heating type composed of the casing with jacket and shaft with a disc which contains steam or other heating media, disc dryer can dry all kinds of animal waste in an atmosphere controlled environment with multipoint thermal control, such as poultry entrails, municipal sludge, textile sludge, catering sludge, chemical sludge, etc.
The discs cover 80% of the total heating surface.
Compared to the other indirect heating dryer, the disc has a compact design and high thermal efficiency.
1. JYG sludge dryer has low energy consumption: due to indirect heating, it does not carry a large amount of air to take away the heat, and the outer wall of the dryer is provided with a thermal insulation layer.
2. JYG sludge dryer has low use cost: it has a huge heat transfer surface per unit effective volume, which shortens the treatment time, reduces the size of the equipment, and greatly reduces the building area and building space.
3. Wide range of materials to be treated: different thermal media are used to treat both heat-sensitive materials and materials requiring high-temperature treatment. Common media include steam, heat transfer oil, hot water, cooling water, etc., which can be operated continuously or intermittently. It can be used in many fields.
4. Small environmental pollution: vacuum or small air volume is used to take away the moisture in the material. The entrainment of dust and material is very small, and the evaporation of the material solvent is very small, which is convenient for treatment. Closed-circuit circulation can be adopted for contaminated materials or working conditions requiring solvent recovery.
5. Low operation cost: low-speed mixing and reasonable structure, small wear, and low maintenance cost.
6. Stable operation: due to the special compression expansion mixing function of the wedge-shaped blade, the material particles are in full contact with the heat transfer surface. In the axial range, the temperature, humidity, and mixing gradient of the material are very small, so as to ensure the stability of the process.
Paddle dryer (vacuum disc dryer) has been successfully used in food, chemical, petrochemical, dye, industrial sludge, and other fields.
The characteristics of heat transfer, cooling, and stirring of the equipment enable it to complete the following unit operations: combustion (low temperature), cooling, drying (solvent recovery), heating (melting), reaction, and sterilization.
At the same time, the stirring blade is the heat transfer surface, which increases the heat transfer area per unit effective volume and shortens the treatment time. The heat transfer surface of the wedge-shaped blade also has the function of self-cleaning.
Compression - expansion mixing function makes the materials mix evenly. The material moves in a "piston flow" along the axial direction. In the axial range, the gradient of temperature, humidity, and mixing degree of the material is very small. Using heat transfer oil or steam as a thermal medium, the paddle dryer can complete low-temperature combustion.
For example, the combustion of calcium sulfate dihydrate (Ca2SO4 · 2H2O) is transformed into calcium sulfate hemihydrate (Ca2SO4 · 1 / 22h2o). Sodium bicarbonate (NaHCO3) is converted into soda ash (na2hco3) by calcination. The cooling medium, such as water and cooling brine, can be used for cooling. For example, the paddle-type soda cooler used in the soda ash industry replaces the old air-cooled soda cooler, saving energy and tail gas treatment equipment and reducing operating costs. Drying, the main function of the equipment does not to use hot air, so that solvent recovery, energy consumption, and environmental control are in an ideal state of easy treatment. It is especially suitable for solvent recovery, flammable, and easily oxidized heat-sensitive materials. It has been widely used in fine chemical, petrochemical, and dye industries. In the axial section, the uniformity of temperature, humidity, and mixing degree makes the equipment can be used to heat or melt or react with some solid materials. It has been successfully used in compound fertilizer and modified starch industries. The paddle dryer can be used to sterilize food and flour. The large heating area in the unit effective volume can quickly heat the material to the sterilization temperature, avoiding the change of material quality caused by long-time heating.
