Continuous Sludge Pyrolysis Machine

Continuous Sludge Pyrolysis Machine

The Continuous Sludge Pyrolysis Machine decomposes organic waste such as municipal, industrial, or oilfield sludge into high-value-added energy and resources through high-temperature thermochemical decomposition (pyrolysis) in an anaerobic or hypoxic environment via continuous feeding, continuous reaction, and continuous discharge.

 There are many features of the continuous sludge pyrolysis machine, such as:

1.It has strong adaptability and tolerance to raw materials and is used in four major fields: soil remediation, solid waste treatment, hazardous waste treatment, and resource recycling. Raw materials can be directly processed in the production line.

2. The pyrolysis process does not cause coking at all. A unique anti-coking device is added inside the cracking reactor, which can complete the gas-liquid-solid separation of materials at a lower temperature without sticking to the wall.
3. Non-condensable combustible gas can be used as fuel for heating, saving energy, and reducing emissions.
4. Oil and gas cooling adopts a simple process of indirect cooling with circulating water, and the processing cost is much lower than other waste treatment processes and methods at home and abroad.

5. The production line has a high degree of automation. Through the PLC/DCS automated intelligent control system, each link and process control point in the equipment is monitored, collected, displayed, calculated, processed and issued corresponding instructions in real time, automatically corrected and alarmed, truly realizing intelligent and safe operation, and low staffing requirements; The equipment can run continuously for 24 hours without stopping, and can run continuously for 90 days, with only one shutdown for maintenance;

6. The treatment effect is excellent, and the mineral oil content of the solid product of the sludge after pyrolysis treatment is <0.1%

NO.	Name	Usage
1	Pyrolysis oil	• Can be sold directly.
		• Reprocessed into diesel and by waste oil refining equipment.
		• Can be used as fuel for an iron factory, power plant, cement factory, restaurant, etc.
2	Reduced soil	• Can be sold directly.
		• Can be used as backfill soil, etc., according to local requirements.
3	Combustible gas	• Can be used as fuel to heat the reactor.

1. What types of sludge can a continuous sludge pyrolysis system process?

Bottom sludge, tank bottom sludge, refinery sludge, crude oil sludge, petroleum sludge, engine sludge, drill cuttings, etc.
Note: The oil content, water content, and solid content of sludge from different sources vary significantly, which will affect the oil yield and process parameter settings.

2. What is the oil yield of a continuous sludge pyrolysis? What are the final products?

The oil yield varies considerably depending on the raw materials, generally ranging from 30% to 70%.
Final products of sludge pyrolysis include: fuel oil, water, and solid residue (sand). The produced fuel oil has a calorific value of approximately 9000-10000 kcal/kg and can be sold directly as industrial fuel or further processed into non-standard diesel fuel using distillation equipment.

3. How to solve the problem of coking and wall adhesion during continuous sludge pyrolysis?

Specialized equipment should be equipped with an anti-coking device: Continuous equipment with an anti-coking device can continuously peel off the attached coke during pyrolysis.

Material: It is recommended to use a furnace liner made of high-temperature-resistant and corrosion-resistant stainless steel.
