Continuous internal heating solid organic cracking furnace

Abstract

The invention discloses a continuous internal heating solid organic matter cracking furnace. The continuous internal heating solid organic matter cracking furnace possesses a fixed horizontal cylinder structure. According to the continuous internal heating solid organic matter cracking furnace, continuous feeding is realized via the upper part of one end of a cylinder body, and continuous slagging is realized via the lower end of the other end of the cylinder body; the cylinder body is provided with a plurality of gas outlets; a rotor is used for dividing wall heating of materials in the cylinder body, and realizing rotating push and stirring materials at the same time; the rotor is composed of a beam barrel and a spiral ribbon with a hollow structure; high temperature smoke is delivered into the beam barrel firstly, and then is delivered into a spiral ribbon internal chamber via flow diversion holes; in the spiral ribbon internal chamber, smoke rotates along with a rotating cylinder, and at the same time flow spirally along the spiral ribbon internal chamber; sufficient heat release is realized, materials are heated, and the smoke is discharged from the beam barrel. Dividing wall heat transmission of the smoke with the materials is realized; temperature difference is large; heating area is large; the temperature of discharged smoke is low; heating is uniform; cracking gas can be discharged in time; no secondary cracking is caused; and oil yield is high. The continuous internal heating solid organic matter cracking furnace is scientific and reasonable in structure and technology; processing capability is excellent; cost is low; energy is saved; the continuous internal heating solid organic matter cracking furnace is friendly to the environment, is safe and reliable, and is low in labor intensity; burning dioxin pollution is avoided; reasonable utilization of resources is realized; and market popularization value is high.

Description

technical field [0001] The invention relates to a continuous internal heat type solid organic matter cracking furnace, which belongs to the field of solid organic matter cracking and is used for thermal cracking or carbonization of solid organic matter. Background technique [0002] Every year in my country, a large amount of solid organic matter needs to be treated. Solid organic matter generally includes plastics, rubber, straw, wood, coal powder, residual oil, etc., especially the waste plastics, waste rubber and other solid organic matter contained in the growing urban waste are difficult to degrade. , These general methods containing solid organic matter are direct incineration, incineration only recovers heat, and also produces dioxins and other pollutants, which are generally resisted by local people, resulting in unreasonable use of resources; similarly, burning straw in rural areas pollutes the air and wastes resource. These solid organics are treated by thermal crac...
