Oil sludge is a kind of hazardous waste produced in industrial production, which contains much oil and a few impurities such as wax, asphaltene and colloid. Therefore, the oil sludge has a high recovery value. The continuous oil sludge pyrolysis plant can recycle and treat the oil sludge to reduce the environmental pollution brought by the oil sludge, in addition, the oil obtained from the oil sludge can also bring economic benefits.
Continuous oil sludge pyrolysis plant
Continuous oil sludge pyrolysis plant manufactured by Henan DOING adopts the principle of pyrolysis, which can pyrolysis the oil sludge, chemical sludge, residue and other wastes at high temperature to obtain fuel oil. Continuous oil sludge pyrolysis plant is a completely closed operation of the system. Its degree of automation control is relatively high. Feeding and discharge slag do not need manual operation. Most operations are mechanical automatic execution.
The main components of continuous oil sludge pyrolysis plant include continuous feeder, continuous rotary pyrolysis reactor, continuous slag discharge, continuous heat exchanger, continuous dry gas recovery unit, continuous flue gas purification discharge unit and continuous automatic dust collector, etc.

The main working process of continuous oil sludge pyrolysis plant
1. Feeding
Take different feeding modes according to the state of raw materials. If it is solid, it can be directly fed. If it is liquid, it needs to be fed in a ton bag, and then the oil mud is sent into the pyrolysis reactor through a sealed screw feeder.

2. Heating
Heating the pyrolysis reactor of continuous oil sludge pyrolysis plant by any fuels such as coal, natural gas, liquefied petroleum gas, etc. When heated to 100 degrees Celsius, the moisture in oil sludge will take the lead in evaporation, internal temperature rise along with the pyrolysis reactor, to a certain extent, oil sludge pyrolysis to produce oil gas, and then flow into the buffer tank, the oil gas in the large molecules will liquefied the collection for the heavy oil into heavy oil tank, small molecules of oil gas rose up into the cooling system.
3. Cooling
The light oil gas enters the condenser uniformly. Through the three-stage condensation system, the oil gas will be liquefied to fuel oil and stored in the tank. The non-condensable gas will be desulphurized in the water seal and then circulated to the pyrolysis reactor to provide heat as heating fuel, thus saving fuel cost.

4. Slagging
After all the above operations are completed, the slag can be discharged through the automatic screw unloading machine. The slag is mainly composed of soil.
Advantages of continuous oil sludge pyrolysis plant
1. The pyrolysis reactor is rotated in vitro, and the reactor body is evenly heated at 360 degrees, which can extend the life of continuous oil sludge pyrolysis plant.
2. There is a turnover device inside the reactor, which needs to be turned over more than 4000 times in the process from feed to discharge. The waste oil sludge is continuously forced to turn in the reactor and is highly dispersed. In this way, the oil sludge can be fully pyrolyzed and the oil yield can be improved.

3. The pyrolysis reactor adopts the rotary varus continuous heating mode. The waste oil sludge runs along the inner wall of the reactor and is in direct contact with the surface of heat transfer. So that heat transfer speed is fast, which can save the reaction time.
4. The production scale can be adjusted. The continuous oil sludge pyrolysis plant can combine multiple pyrolysis reactor in tandem to achieve large-scale production, and can also be further adjusted according to customer requirements.
Final products and their applications from continuous oil sludge pyrolysis plant
Fuel oil, soil and water can be obtained from oil sludge through the treatment of continuous oil sludge pyrolysis plant. Fuel oil can be used directly in steel works, boilers for heating, heavy oil generators, cement plants, etc. The resulting soil is not much different from ordinary soil and can be used directly to make bricks or pave roads.
