Embodiment 1

[0020] During the electric carbonization process, when the carbonization furnace is at 400°C-700°C, a large amount of soot mixture will be produced. First, the soot mixture will be introduced into the condenser for condensation and separation. The heavy oil component in the soot mixture accounts for more than 80% of its weight After condensing, it falls into the collection tank and is used as chemical raw materials. The heavy oil can be used to make coatings and waterproof materials; then the flue gas mixture that removes most of the heavy oil components is passed into the burner and mixed with natural gas and burned in the furnace together. Heat is introduced into the drying equipment to dry granular carbon, in which the flue gas mixture mainly contains carbon monoxide, carbon dioxide, nitrogen monoxide, nitrogen dioxide and a small amount of ash, and the weight ratio of the flue gas mixture input to the burner to natural gas is 1 : 3; the flue gas mixture produced by combusti...

Abstract

The invention discloses a method for recycling a lampblack mixture produced in the electrical carbon carbonization process, and the method comprises the following steps: (1) firstly introducing the lampblack mixture produced in the electrical carbon carbonization process into a condenser to carry out condensation and separation; and allowing a heavy oil component in the lampblack mixture to fall into a collecting tank to serve as a chemical material after being condensed; (2) introducing the smoke mixture in which a large part of the heavy oil component is removed into a burner to mix with natural gas to burn in a hearth; and introducing heat obtained from the burning into other equipment to use; and (3) introducing the smoke mixture generated from the burning in the step 2 below the liquid level of an alkaline aqueous solution through a pipeline to carry out purification treatment, and discharging a purified gas into atmosphere. By adopting the method disclosed by the invention, wastecan be changed into a precious resource; the waste lampblack is recycled, a chemical material and heat are produced while the environmental pollution is reduced; the value is created; an energy source is saved; and the environment is protected.

Description

technical field [0001] The invention relates to the field of preparation of new carbon materials, in particular to a method for recovering electric carbonized oil fume mixture. Background technique [0002] During the carbonization and activation process of electric carbon, a large amount of soot mixture will be produced. The main component of the soot mixture is heavy oil, which contains a certain amount of carbon monoxide, carbon dioxide, nitrogen monoxide, nitrogen dioxide and a small amount of ash. Heavy oil can be used to make Coatings, waterproof materials, etc. If the soot mixture produced during the carbonization activation process is allowed to be discharged into the air, it will not only seriously pollute the environment, but also cause a serious waste of resources. Contents of the invention [0003] The object of the present invention is to provide a method for recovering electric carbonization oil fume mixture aiming at the defects existing in the prior art. ...
