Introduction of sludge treatment process
The sludge treatment process refers to the sludge treatment by the dry distillation method to prepare the sludge carbon particles and the sludge ceramsite. The whole set is a chemical reaction process carried out under closed, anaerobic and high temperature conditions, and the sludge is subjected to high temperature heating. Thermal decomposition produces flammable gas and material charcoal, which effectively decomposes sludge, realizes resource utilization, protects the environment, and achieves benefits.
A sludge treatment plant is made up of several Main components:
(1) Sludge Drying Treatment Skid Mounted
(2) Sludge Dry Distillation Skid Mounted
(3) Exhaust Gas Treatment Skid Mounted
(4) Water Treatment Skid Mounted
(5) System Controlled Skid Mounted
The sludge treatment plant has the capacity on treat 20,000 tons dried sludge with a moisture content of 20% annually. The sludge treatment plant adopts a modular design. All the pry bodies are respectively installed in the 40GP container. The transportation is convenient, the land occupation is small, the adaptability is strong, and it is not affected by urban planning.
Sludge treatment key technology
The concentrated and dehydrated municipal sludge contains a large number of pathogens, parasites and harmful substances (such as heavy metals, organic compounds, etc.), and must follow the principle of “reduction, stabilization, harmlessness and resource utilization”, to avoid secondary pollution to the environment.
In the process of equipment development, the Sludge Carbonization Rotary kiln Incinerator always follows the design concept of “advanced application, safety and reliability, economical rationality, low energy consumption and energy saving”. The designed treatment capacity is 48t/d (the sludge moisture content is 20%), and the sludge carbon particles are produced. The sludge ceramsite can be adapted to 0.5~2 times of design and output change to realize “a set of equipment and two kinds of processes”, and complete the first set of equipment development and standard demonstration in China.
