What are the advantages of low temperature sludge dryer

At present, the figure of sludge dryer can be seen in many industries and is welcomed by many enterprise users. The following is about the low temperature sludge dryer equipment where?

First of all, from the low temperature sludge dryer process. The difference between this equipment and other dryers is that the low temperature drying mode is adopted, that is, by reducing the drying temperature and increasing the air volume and wind speed, the sludge can be dried. Because some hazardous waste sludge contains harmful substances, if the calorific value exceeds the calorific value required for volatilization of harmful sludge, the harmful substances in the sludge will volatilize through the gas, which will not only cause certain damage to the dryer cylinder, but also increase the difficulty for the later tail gas treatment. The remarkable effect of low temperature drying treatment is energy saving, which can not only effectively reduce the volatilization of harmful substances in sludge, but also greatly reduce the energy consumption.

Secondly, the low-temperature sludge drying machine has strong adaptability, which can dry municipal sludge, electroplating sludge, urban sludge, chemical sludge, steel sludge, papermaking sludge, printing and dyeing sludge, oily sludge, pharmaceutical sludge, iron vanadium slag, lead-zinc slag, coal slime, etc. At the same time, it has a wide range of fuel applications, such as coal, gas, oil, electricity, biomass fuel, steam and boiler flue gas waste heat, etc., which can be used as the heat source of equipment.

Third, the whole equipment system is easy to control. The low temperature sludge dryer adopts automatic control, which is easy to operate, stable and reliable performance, and can operate continuously for a long time without fault.

Fourth, the environmental protection of the equipment. The whole production line is tightly sealed and operated under negative pressure without any gas leakage during operation. The tail gas after production is transported to dust removal equipment by induced draft fan for filtration, purification and dust reduction, so as to meet the national emission standards.

Fifth, the structure of the equipment. The low-temperature sludge dryer adopts three sleeve structure, that is, three cylinders with different diameters are embedded together, which expands the storage space inside the cylinder, reduces the equipment volume, reduces the occupied area and equipment installation.

Sixth, the warm sludge dryer also uses a hot air distribution system, which can automatically adjust the temperature and air volume according to the different moisture content of sludge in the drying process, which greatly saves energy consumption. At the same time, the outer wall of the cylinder is provided with an insulating layer, so the heat loss is very small.

Low temperature sludge dryer can realize harmless, stabilization, reduction and resource disposal of sludge. The economic value of the dried sludge is improved. It can be used for landfill, agricultural manure, composting, incineration, and production of various building materials (such as cement, brick and tile, ceramsite, etc.) to drive the new economic development of enterprises.
