Reflective heated waste rubber and waste plastic thermal cracking device

Abstract

The invention relates to a reflective heated waste rubber and waste plastic thermal cracking device. The device comprises a feeder, a cracking chamber and two spiral cracking devices. The spiral cracking devices are vertically arranged. Two combustion furnaces are respectively arranged on both sides of the lower part of the cracking chamber. Separators are respectively arranged in a vertical direction outside the spiral cracking devices in the cracking chamber. The separators and inner walls on both sides of the cracking chamber form reflective hot air ducts, respectively. Hot air channels are reserved on the upper parts. Compared with conventional cracking devices, the reflective heated waste rubber and waste plastic thermal cracking device provided by the invention is high in degree of automation, large in production capacity and low in manufacturing cost which is half of that of conventional rotary furnaces, and the daily production capacity is twice as much as that of the conventional rotary furnaces. The spiral cracking device is prevented from being directly burned by flame, the upmost spiral cracking device is heated first to reach the higher temperature required by a feeding part. The reflective heated waste rubber and waste plastic thermal cracking device heats uniformly and has high thermal cracking efficiency. Retention time of hot air in the furnace is prolonged, so that the heat is adequately used, and the energy sources are saved. The reflective heated waste rubber and waste plastic thermal cracking device is in totally-enclosed continuous production and low in labor intensity, and no secondary pollution is generated.

Description

technical field [0001] The invention relates to a reflective heating waste rubber and waste plastic pyrolysis device, which is a double-reflection pyrolysis device Background technique [0002] Waste rubber and waste plastic thermal cracking renewable energy technology has made great progress in recent years [0003] Pyrolysis equipment also emerged as the times require, with a wide variety, but most of them are intermittently produced pyrolysis equipment, with low output, high labor intensity, and difficult operation, which restrict the development of this industry to varying degrees. Although the "continuous cracking device for waste plastics" (application number 201120077319.6) applied by the inventor in 2011 solved the problem of continuous production with continuous feeding, the combustion furnace of this design directly heats the bottom spiral cracker, which not only heats unevenly , and where high temperature is required at the top feed end, high temperature ...

[0003] Pyrolysis equipment also emerged as the times require, with a wide variety, but most of them are intermittently produced pyrolysis equipment, with low output, high labor intensity, and difficult operation, which restrict the development of this industry to varying degrees.

Although the "continuous cracking device for waste plastics" (application number 201120077319.6) applied by the inventor in 2011 solved the problem of continuous production with continuous feeding, the combustion furnace of this design directly heats the bottom spiral cracker, which not only heats unevenly , and the place where high temperature is required at the top feed end cannot guarantee high temperature, resulting in low cracking efficiency
