Abstract

The invention discloses a chain plate natural gas heating sludge drying device and a sludge drying processing method. The device comprises a drying furnace, a chain plate transmission belt, and a natural gas heater; wherein the chain plate transmission belt and the natural gas heater are arranged in the drying furnace and the natural gas heater is arranged under the chain plate commission belt. The chain plate natural gas heating slug drying device provided by the invention has the advantages of good drying effect, more economic, and environment-friendliness.

Description

technical field [0001] The invention relates to a sludge drying device and system, in particular to a chain plate type natural gas heating sludge drying device and a sludge drying treatment method. Background technique [0002] Sludge is a kind of viscous substance produced in the process of sewage treatment. The composition of sludge varies greatly, which varies with the source of sewage, sewage treatment process and season. For large-scale urban sewage treatment plants, due to the large amount of industrial wastewater discharged into the system, the heavy metal content in sewage sludge is relatively high, among which copper and zinc content are often close to or exceed the acceptance standards for sludge as agricultural fertilizers. Sewage from small and medium cities is mainly composed of Domestic sewage is the main source, so there is generally no problem of excessive heavy metals. The sludge discharged from the sewage treatment plant is generally a loose colloidal past...
