Electromagnetic energy quick sterilization sludge dehumidifying anhydration system
Technical field
The present invention relates to technical field of sludge treatment, especially sludge drying system.
Background technology
Sludge drying is the further part of sewage disposal, with the quickening of Urbanization Process In China, municipal sewage plant
Still it is continuously increased, sludge yield is also in the gesture maintained sustained and rapid growth.The concern of society promotes the national processing to sludge of having to
Disposal is paid attention to, and national attention has promoted the formation in specific resistance to filtration market again.At present, metropolitan sludge treatment becomes
Difficult and costliness is obtained, the haul of long range sludge, fuel and freight rise, and Sludge landfill consumes a large amount of land resources, and
Expense rises, and wet mud directly burns somewhat expensive, and because the problems such as haze, public opposition builds incinerator in city.
Existing common sludge drying system is based on mechanical dehydration and Thermal dehydration, and main plant equipment has:Rotary drum vacuum mistake
Filter, Revolving-drum centrifuge, plate and frame filter press, band press filter dewatering machine, spiral pressing dehydrator, paddle machine, sleeve machine or stream
Change bed etc..However, there is problems with actual implementation process:
1st, when using Thermal dehydration, in sludge drying processing procedure, the pollutants such as flue dust, flue gas, deep fat can be produced, so that
Surrounding environment is adversely affected.
2nd, when using mechanical dehydration, what is sloughed due to mechanical dehydration is only free clearance water in sludge, though through dehydration,
Sludge moisture content still suffers from 75%~85% or so, but 75%-85% moisture content can not cause sludge to be directly disposed, the inside
The poisonous and harmful substance contained is not also processed, therefore, with sludge drying drying efficiency it is low the problem of.
3rd, complicated, cost is high.
The content of the invention
It is an object of the invention to provide a kind of electromagnetic energy quick sterilization sludge dehumidifying anhydration system, sterilization, desiccation are realized
