Tunnel type pyrolysis gasifying device and pyrolysis gasification method

Abstract

The invention provides a tunnel-type pyrolysis gasification device and a pyrolysis gasification method. The tunnel-type pyrolysis gasification device is provided in sequence with a feeding table, a pyrolysis furnace body and a discharging table from a feeding end; both sides of the pyrolysis furnace body are provided with sealing furnace doors, the furnace body is internally provided with a pyrolysis chamber, a combustion chamber and a flue between the pyrolysis chamber and the inner wall of the furnace body, the upper part of the furnace body is provided with an exhaust port and a pyrolysis gas pipeline, the lower part of the furnace body is provided with a pyrolysis gas combustion nozzle and a fuel combustion nozzle, wherein, the tunnel-type pyrolysis gasification device also comprises an electric push rod, a feed frame and a slide rail, the feed frame filled with the feeds is pushed by the electric push rod to get into and out of the furnace body, the slide rail is arranged on the lower part of the furnace body so that the feed frame can slide forwards thereon. By employing the tunnel-type pyrolysis gasification device of the invention, in accordance with the pyrolysis gasification method of the invention, not only the semi-automatic feeding and discharging can be realized to improve the productivity on the basis of the favorable sealing effect, but also the materials can be pyrolyzed completely with simple operations, high metal recovery ratio, good energy-saving effect and little environmental pollution.

Description

technical field [0001] The invention relates to the field of environmental protection solid waste treatment, in particular to a tunnel-type pyrolysis gasification device and a pyrolysis gasification method suitable for the cleaning treatment and resource recovery of waste wires and cables, electronic circuit boards and waste motors. Background technique [0002] In recent years, the recycling of metal resources has been highly valued by countries all over the world. How to recycle metal resources in waste cables and wires and waste motors is a key technology. Among them, the use of pyrolysis to recover metals has gradually attracted the attention of many scientific researchers. Its advantage is that not only can metal resources be recovered efficiently, but also the produced pyrolysis gas and tar are valuable products that can be recovered simultaneously. Therefore, the application of pyrolysis to recover metal resources in waste wires and cables and waste motors has the adv...

Problems solved by technology

[0005] The common disadvantage of this type of furnace is that the operation of feeding and discharging materials is time-consuming and laborious, the operability is not high, and the production efficiency is generally low

In addition, there is no air flow stirring device in the pyrolysis chamber of this kind of pyrolysis furnace, which makes it difficult to make the material reach a uniform temperature, and the pyrolysis is not thorough enough, which is not conducive to the separation of the wire insulation layer and the metal
