Abstract

The invention discloses a normal-pressure infiltration catalytic separation structure of a waste polyethylene (PE) strip steel corrugated pipe and a technology for the structure. On one hand, the normal-pressure infiltration catalytic separation structure of the waste PE strip steel corrugated pipe comprises a reactor, a reactor cover, a steam cooling tank and a charging basket, wherein an electric heating pipe is arranged in the reactor; the reactor cover is connected with an electric block arranged on a hoisting support through a sling; the charging basket is hoisted into the reactor through the electric block; and a steam discharge pipe is arranged in the steam cooling tank, and two ends of the steam discharge pipe respectively extend into the reactor. On the other hand, the invention also discloses the technology for implementing the structure. The technology is simple, easy to operate and high in production safety; and peculiar smell, dust and noise are not generated, waste gas, waste water and waste smoke are not discharged, irradiation is not generated, waste slag is not discharged, electrical energy is saved, separation is simple, a separation effect is good, and a steel plate can be manually and randomly taken out of plastic.

Description

technical field [0001] The invention relates to an atmospheric pressure infiltration catalytic separation structure of a waste secondary PE strip steel corrugated pipe, in particular to an atmospheric pressure infiltration catalytic separation structure of a secondary PE strip steel corrugated pipe and a process thereof. Background technique [0002] With the massive construction of national infrastructure projects, PE strip steel corrugated pipes are increasingly used in municipal engineering construction. At the same time, the waste and defective products produced by pipe manufacturers in the production process cannot be recycled due to the connection of steel and plastic, which has become a major problem for manufacturers. [0003] Current status of reuse of waste PE corrugated pipes: According to the survey, the current large manufacturers have about 20-60 tons of waste and defective products in the production process every month. At the same time, many municipal projec...
