Sludge Carbonisation Furnace Working Principle

Sludge is the residual sediment after sewage. It contains sediment, particulate matter, floating matter, etc. According to different sewage after treatment. The proportion of harmful substances in its sludge is also different. Common sludge are: industrial wastewater sludge, municipal sludge, domestic sludge, waterworks sludge, aquaculture wastewater sludge and so on. Sludge has a large number of harmful substances, even to toxic residues. It will cause some pollution to the environment and soil. Sludge carbonisation furnace is a modern and efficient environmental protection equipment. It plays an important role in the field of sludge carbonisation.

Sludge carbonisation furnace working principle:
Carbonise the sludge by high temperature cracking under the condition of oxygen-free atmosphere. Carbonise the organic components in the sludge. Put the sludge through anaerobic pyrolysis treatment. Thus the organic matter is converted into biochar. The water in the sludge can be evaporated. It also reduces the volume of sludge. There are many microorganisms and heavy metal pollutants in the sludge. After high temperature decomposition, it can be converted into harmless solid residue. Thus, the sludge can be reused in a harmless, reduced and resourceful way. Firstly, the sludge is sent to the sludge carbonisation furnace through a feeding device. The furnace is externally heated and the temperature is raised to a suitable pyrolysis temperature. The sludge is then pyrolysed in the closed carbonisation furnace. High energy pyrolysis gas is released. Eventually. It is then discharged by the discharge system. The gas produced by pyrolysis is combusted, sprayed and purified. Thus providing energy inside the carbonisation furnace.

Sludge Carbonisation Furnace Working Principle

Sludge carbonisation furnace components:
The whole production line is composed of: carbonisation furnace, inlet and outlet device, gasifier, burner, gas purification system, PLC control system and so on. Gas-making equipment in the pre-gasification furnace. It can provide the heating body for the sludge carbonisation furnace in the preliminary stage. At the bottom of the carbonisation furnace, the furnace body is heated externally by the burner. Carbonisation furnace includes: feeding conveyor, furnace body, feeding port, connecting pipe, active sprocket, chain, reducer, motor frame, discharge port, screw conveyor and other components. The inside of the furnace body adopts the screw propulsion type. It can heat the material fully and evenly. Gasifier gas and flue gas from dry distillation are sent to gas purification system through induced draft fan to be converted into combustible gas. Then it reaches the combustion chamber at the bottom of the dry distillation furnace through the gas pipeline for combustion. It can be used as carbonisation heat source for continuous production. Thus completing the resource recovery. There will be no secondary pollution.
