Textile printing and dyeing sludge Dryer - Hollow Blade Dryer, hollow shaft densely arranged with wedge-shaped hollow blades, heat medium flows through the hollow shaft through the blade. There is a large area of heat transfer within the effective volume of the unit, and the heat medium can be water vapor, hot water, or thermal oil. The heat transfer medium passes through the rotary joint and flows through the jacket of the housing and the hollow agitation shaft. The hollow agitation shaft has different internal structures according to the type of the heat medium to ensure better heat transfer effect. When steam is applied to the paddles and jackets, heating is performed at the same time as the upper part of the discharge outlet is also passed through the heated dry air to further dry, which greatly increases the drying strength of the equipment. The evaporated water is taken out of the Drying Equipment by the exhaust gas, and the moist air is discharged outside by the induced draft fan. Textile printing and dyeing sludge dryer - hollow blade dryer is suitable for industrial sludge drying, electroplating sludge drying, chemical sludge drying, paper sludge drying textile printing and dyeing sludge dryer
Features: 1) low energy consumption of blade dryer : Due to indirect heating, there is not a lot of carrying air to carry away heat and the thermal efficiency is high. 2) The effective volume of the paddle dryer has a large heat transfer surface, which shortens the processing time and the size of the equipment becomes smaller. It has greatly reduced the construction area and the construction space. 3) Wide range of processing materials: Different media can be used to handle both heat-sensitive materials and high-temperature materials. Commonly used media are: water vapor, thermal oil, hot water, cooling water (cooling) and so on. Both continuous and intermittent operation can be applied in many fields. 4) Small environmental pollution: The amount of carried air is very small, and there are few entrained dust materials. Closed-circuit circulation may be used for contaminated materials or conditions where solvents are to be recovered. 5) Low operating costs: The equipment is operating normally, only 1 person/day. Low speed stirring and reasonable structure. The amount of wear is small and maintenance costs are low. 6) Operation stability: Due to the special compression-expansion stirring action of the wedge-type paddle, the particle components of the material are in contact with the heat transfer surface. In the axial range, the temperature, humidity, and mixing temperature gradient of the material are small, and the heat transfer coefficient is large. .
