Rotating bed retort furnace

Abstract

The invention discloses a rotating bed dry distillation furnace comprising a circular ring-shaped furnace body, a charging plate, a radiation pipe, at least one material turning device, an oxygen distributor and an oxygen device, wherein an accommodating space is limited in the furnace body, and a feed port and a discharge port are formed in the furnace body; the charging plate is rotatably arranged in the accommodating space; the radiation plate is arranged in the accommodating space and is positioned above the charging plate; the at least one material turning device is arranged between the charging plate and the radiation plate; the material turning devices are arranged along the periphery of the furnace body and are spaced from each other; the oxygen distributor is arranged on the material turning device; and the oxygen device is connected with the oxygen distributor. According to the rotating bed dry distillation furnace disclosed by the invention, the oxygen device and the oxygen distributor are arranged, oxygen can be introduced into the furnace body through the oxygen device, oxygen introduced from the oxygen device can be subjected to incomplete combustion reaction with semi-coke which has a certain temperature, and semi-coke is partially oxidized to generate CO (carbon monoxide) and release heat, thus the pyrolysis temperature of materials is further increased, and full pyrolysis of the materials is achieved.

Description

technical field [0001] The invention relates to the technical field of pyrolysis, in particular to a rotary bed carbonization furnace. Background technique [0002] As global oil demand continues to rise, international oil prices continue to rise, making countries around the world actively looking for alternative resources for oil. Semi-coke, tar and non-condensable gas can be obtained by low-temperature dry distillation of lignite. Therefore, using coal to produce gasoline and diesel components through dry distillation technology has become an important alternative for petroleum resources. [0003] The rotary bed is used as the pyrolysis technology of the retort furnace, which has the characteristics of thin material layer and fast pyrolysis, and can realize large-scale processing of raw coal to a certain extent. However, limited by the thermal conductivity of coal, the coal is heated unevenly. Therefore, the quality of the product is not uniform, and it is difficult to fu...

[0003] The rotary bed is used as the pyrolysis technology of the retort furnace, which has the characteristics of thin material layer and fast pyrolysis, and can realize large-scale processing of raw coal to a certain extent. However, limited by the thermal conductivity of coal, the coal is heated unevenly. As a result, the quality of the product is not uniform, and it is difficult to further increase the output of the rotary bed retort furnace by increasing the thickness of the material layer, and the coal processing capacity is low
