How to reduce the coking situation of waste oil sludge pyrolysis process?

Due to the high viscosity and strong corrosiveness of waste oil sludge raw materials, during the high-temperature pyrolysis process, as the furnace temperature gradually increases, it is easy to adhere to the inner wall of the main furnace of the waste oil sludge pyrolysis equipment, forming coking and carbon deposition on the surface of the pyrolysis furnace. So, do you know how to effectively reduce the coking situation of waste oil sludge pyrolysis process?

Oil sludge waste for treatment pyrolysis

Henan Doing Company provides three de-coking solutions for you to choose from:

1. Improve the material of the pyrolysis furnace

One of the effective ways to reduce the coking situation of waste oil sludge pyrolysis equipmet is to improve the material of the furnace, and choose stainless steel instead of carbon steel. The use of stainless steel waste oil sludge pyrolysis equipment can effectively reduce the phenomenon of sludge coking and wall adhesion due to high viscosity. On the other hand, sludge is highly corrosive, and the pyrolysis oil outlet temperature is generally around 400°C, which is much higher than waste tires (pyrolysis oil outlet temperature 320~350°C). The use of stainless steel pyrolysis furnace material is resistant to high temperature and corrosion, which can extend the service life of the equipment.

2. Add decoking device

Another effective way to reduce the coking situation of waste oil sludge pyrolysis process is to add decoking devices to the inner wall of the oil sludge pyrolysis plant furnace, such as energy balls, decokers, maces, scrapers, etc. The decoking device installed in the pyrolysis reactor of Henan DOING waste oil sludge pyrolysis equipment can increase the dispersibility and thermal conductivity of waste oil sludge, creating favorable conditions for the balanced and rapid heating of materials. On the other hand, the formed coking can be removed and new coking can be prevented by scratching and friction.

3. Manual regular cleaning

After the waste oil sludge pyrolysis equipment has been running for a period of time, it is recommended to conduct manual inspections and perform manual decoking and maintenance regularly. The process of manual decoking should pay attention to safety because of the nature of the decoking of the pyrolysis furnace. Avoid using friction sparks and other operating methods, which will cause irreversible effects on the sealing system, thereby affecting the safety and stability of the waste oil sludge pyrolysis equipment.

The above are three effective ways to reduce the coking situation of waste oil sludge pyrolysis process. The waste oil sludge pyrolysis equipment designed and manufactured by DOING for customers in Shaanxi province of China, Malaysia, Colombia, etc. are all made of 304 stainless steel, and the pyrolysis furnace is equipped with a decoker to achieve stable and continuous operation of the pyrolysis equipment. We have successful waste oil sludge pyrolysis equipment project cases for your reference.
