Sludge Continuous Carbonisation Furnace Process

Wastewater treatment plants go through water treatment. Sludge is produced. It contains: sediment, particulate matter, floating matter. Sludge is often divided into: industrial wastewater sludge, domestic sewage sludge, municipal sewage sludge and so on. In solid waste, sludge is a very large toxic and harmful substances. If this is not well treated. It will cause serious pollution to the environment and soil. Therefore, the treatment of sludge needs to consider a variety of comprehensive factors. In order to solve its environmental problems. Then launched the city sewage treatment plant sludge carbonisation furnace process. The following is a detailed introduction:

Sewage treatment plant sludge carbonisation furnace process

Sludge carbonisation technology has high application value. It can effectively deal with urban sludge. Not only can the sludge be treated efficiently, but also valuable charcoal can be obtained. Sludge treatment plant should pay active attention to sludge carbonisation technology, which can improve the level of sewage and sludge treatment. High-temperature sludge carbonisation furnaces dry and pyrolyse sludge without pressure, and use carbonisation for high-temperature carbon neutralisation to obtain examples of carbonisation. The calorific value contained in the sludge during the production process and the air dust generated by the charring furnace can be continuously pyrolysed. This results in charred pellets. The amount of sludge can be reduced. Thus, the sludge can be harmless and recycled. The reason why sludge carbonisation technology has received widespread attention. It can remove the cellular water in sludge, and the proportion of char in the slurry increases dramatically. Under the action of dry distillation and pyrolysis. Converts organic matter into water vapour. No condensation of gas or char.

The sludge carbonisation furnace system is mainly a combination of: carbonisation furnace body, feeding conveyor, burner, second combustion chamber, cooling device, discharging system, environmental protection system, control system and so on. The sludge carbonisation furnace first pre-treats and dries the sludge. The furnace body is heated through the burner. The furnace body adopts spiral propulsion type, which gradually advances the material forward while rotating. And heating pyrolysis. So as to achieve the purpose of sludge carbonisation. The flue gas produced by the whole set of sludge carbonisation furnace production line is collected to the flue gas purification and treatment system through the induced draft fan under negative pressure. The combustible gas then enters into several combustion chambers of the furnace body for combustion through the pipeline. The charring temperature and advancing speed can be controlled and adjusted by PLC. The continuous pyrolysis treatment of sludge carbonisation can be realised. Thus, the sludge can be recycled.
