The low-temperature drying process of sludge is a process that improves drying efficiency by reducing the drying temperature and appropriately increasing wind speed and air volume within a set temperature range. What are the application characteristics of low-temperature drying equipment? Let's analyze together:
(1) By controlling the working conditions of the equipment, the temperature of the hot dry air in the drying room is between 10-75 ℃, which can meet the high-quality drying requirements of thermosensitive materials.
(2) Energy saving. Heat pumps can generate a large amount of heat by consuming a small amount of work, and their SMER (water content in materials that are dehumidified per unit of energy) is usually 1.0-4.0 kg/kWh, while the SMER of traditional convection dryers is about 0.2-0.6 kg/kWh.
(3) Convenient temperature and humidity control, using intelligent control to automatically control temperature and humidity.
(4) Environmental protection. Pollution is caused by the discharge of dry exhaust gas into the environment without material dust, volatile substances, and odors; By directly recovering waste heat through a heat pump to heat dry and cold air, the unit will not cause thermal pollution to the environment.
(5) Low-temperature drying equipment is suitable for a wide range of materials and is not affected by climate. It can be widely used in heating and drying operations in industries such as food, chemical, pharmaceutical, paper products, leather, wood, and agricultural and sideline product processing.
(6) Easy to install. Easy to install and disassemble, with a small footprint, suitable for both indoor and outdoor installation.
(7) Safe and reliable operation. The entire system operates without any hazards, such as flammability, poisoning, and short circuits, which may exist in traditional dryers. This is a safe and reliable fully enclosed drying system.
(8) Long service life, low maintenance cost, mature technology, stable and reliable performance, and long service life.
(9) Comfortable and convenient, with a high degree of automation and intelligence, the 24-hour continuous drying operation adopts an automatic constant temperature control device.
What are the characteristics of low-temperature drying equipment? Let's take a brief look together.
1. Using low-temperature sludge drying equipment to treat sludge not only has high operating efficiency but also can save costs. In addition, using low-temperature sludge drying equipment, the entire purification process rarely produces other pollutants, making it relatively environmentally friendly. In addition, compared to other devices, this operating process is safer and more reliable. 4. Low-temperature drying has high operating efficiency, adopts advanced technology, is more lightweight, has a long service life, and can be automatically adjusted. Compared with previous facilities, low-temperature sludge drying equipment has greater advantages, such as less time, higher efficiency, and more convenient operation. In addition, after being treated by low-temperature sludge drying equipment, the sludge treatment rate is very high compared to other equipment, and the treatment effect is very delicate with fewer impurities.
