Method and apparatus for continuously and rapidly separating pyrolysis oil

Abstract

The invention discloses a method and an apparatus for continuously and rapidly separating a pyrolysis oil, which is characterized in that a waste rubber, a waste plastic or the pyrolysis oil generated by thermal cracking of biomass is filtered and enters into a first preheater, the preheated pyrolysis oil enters into a cyclone hydraulic separator in a tangential direction, and enables spiral movement downwardly, the impurities spirally flow downwards to an outlet of a cone base due to inertial centrifugal force, the pyrolysis oil is discharged from a center tube at the top and enters into a second preheater for heating, then enters into an evaporator, the certain temperature is kept in the evaporator, steam is continuously introduced in the evaporator, the steam carries the distilled components enter into a condenser from the top of the evaporator together for condensate recovery, and the heavy components are sent from the bottom of the evaporator and cooled to obtain the finished product. The apparatus comprises a filter, a charge pump, the first preheater, the cyclone hydraulic separator, the second preheater, the evaporator in series, the top of the evaporator is connected to the condenser, the bottom of the evaporator is connected to a cooler. The method and apparatus for continuously and rapidly separating the pyrolysis oil have the advantages of high automation degree, and convenient and easy operation.

Description

technical field

[0001] The invention belongs to the technical field of energy, and relates to a new technology for continuous and rapid separation of light components and heavy components of waste pyrolysis oil. Background technique

[0002] my country is the world's largest consumer of rubber and plastics, and the production of waste rubber and waste plastics has also increased sharply. Waste rubber and waste plastics account for about 15% of the total solid waste. If the "black garbage" represented by waste rubber and the "white garbage" represented by waste plastics are not treated effectively, they will not only cause serious pollution to the environment, but also cause a huge waste of resources. For waste rubber and waste plastics, there are currently three main treatment methods: recycling, incineration, and cracking. For waste rubber and waste plastics that are not suitable for recycling and regeneration, incineration can recover energy, but it will cause serious s...
