Description

technical field

[0001] The invention relates to the field of heating equipment, in particular to a heating furnace, a heating system and a method for treating oily sludge using the same. Background technique

[0002] During oil and gas drilling, a large amount of oily sludge will be produced. It contains complex components such as oil, clay, sewage, and various chemical treatment agents. It has the characteristics of high oil content and many organic pollutants, and there is a major risk of environmental pollution.

[0003] The treatment methods for oily sludge mainly include physical, biological and chemical methods. The chemical treatment methods of oily sludge mainly include incineration, chemical demulsification and separation, heat treatment and so on. The heat treatment method is to send the oily sludge into the heating furnace through the transportation device, and a stirring member is installed in the furnace, and the drilling cuttings in the furnace are heated by ...
