Horizontal type slew cylinder structure cracking furnace for waste steel wire blank continuous thermal cracking

Abstract

The invention disclosed a lying posture turnover cylinder cracking furnace which is used in the successive thermal cracking of a waste steel-wire tyre material. There's a below stack gas inlet and a top stack gas outlets on the outside tube of the cylinder; inside being positioned inner turning-over tube drived by transmission system; one side of the inner tube connects the tyre spiral feeder which can change the pitch, and the other side connects the static split product gathering trunk; on the top of the gathering trunk is the outlet of the gas hydrocracking product, while below the gathering trunk is outlet of the solid hydrocracking product, the gathering trunk also connects the spiral discharging device. The waste tyre material which is transferred by the spiral feeder is repeatedly grabbed by the grabbing plank located on the inner wall and pushed to the outlet. The high temperature stack gas counterflows in the passage between the outside and the inside tubes, during the process of the material's axial direction translation and circular direction rotation, the material absorbs the conducted calory from the tube wall to finish the splitting process. The gas product is pulped away by the blower while the solid product is discharged by the spiral discharging device through the bottom canal orifice.

Description

technical field [0001] The invention relates to a horizontal rotary cylinder structure pyrolysis furnace for continuous pyrolysis of waste steel wire blocks. Background technique [0002] With the rapid development of the automobile industry, the number of scrap tires is expected to increase at a rate of more than 20% every year. The large open-air accumulation of these waste tires not only occupies arable land, breeds mosquitoes, destroys the landscape, causes "black pollution" to the environment, but also buryes fire hazards. The non-degradable characteristics of waste tires make them unsuitable for landfill treatment; the crushing and granulation methods consume a lot of energy due to low temperature operation; the incineration method has the disadvantages of generating polycyclic aromatic hydrocarbons and soot and other pollutants. Pyrolysis technology is considered to be the most potential recycling method of waste tires in the 21st century because of its low pollution...

Problems solved by technology

However, the device uses rotating rakes to push the material block to move. When the tire material block is large and the cracked steel wire is long, it is very easy for the steel wire to entangle and ball to block the channel. Therefore, it is only suitable for non-steel tire material block and finely crushed steel wire Thermal cracking of tire blocks
