Plastic magma spray device and method for spraying magma mist

Abstract

A plastic magma spraying device and a method for spraying magma mist relate to the technical field of plastic processing and solve the technical problem of improving the gasification effect of plastic magma. The device includes a spray body, a suction pipe, and a nozzle fixed on the spray body; the spray body has a hollow inner cavity, and the wall of the inner cavity is provided with a feed port communicating with the outside; the nozzle is always Linear pipe body, one end of the pipe body is open, and the other end is provided with a cone-shaped spray port, and its inner cavity is connected to the inner cavity of the spray body through a straw; the inner diameter of the straw is smaller than the inner diameter of the nozzle, and one end of the straw is fixed to the nozzle , and the other end extends into the inner cavity of the spray body. The device provided by the invention can uniformly spray the plastic melt on the melt coating surface of the gasification furnace.

Description

technical field [0001] The invention relates to plastic processing technology, in particular to a plastic magma spraying device and a method for spraying magma mist. Background technique [0002] With the development of the plastic industry, the widespread use of plastic products has brought about a large amount of plastic waste, which has brought a huge burden to the environment. As a measure to save energy and protect the environment, the recycling of plastic waste has become increasingly popular in various countries. attention. [0003] Waste plastic recycling gasoline (diesel) oil technology is a technology to extract gasoline (diesel) oil from waste plastics. This technology first melts waste plastic particles into a slurry, and then injects the plastic melt into a gasifier for gasification and refining. Steam (diesel) oil. In order to improve the gasification completeness of the plastic melt, the plastic melt is usually scraped into a thin film with a scraper after i...

AI Technical Summary

Problems solved by technology

However, the plastic melt film formed by scraping with a scraper is thicker, and it is not easy to scrape evenly; in addition, the plastic melt to be scraped will accumulate on the melt coating surface of the scraper and the gasifier. When scraping, part of the molten slurry will be gasified and carbonized under the high temperature of the gasifier, which will affect the scraping of plastic molten slurry, and then affect the gasification effect of plastic molten slurry

At present, there is still a lack of a method that can timely and effectively coat the plastic melt on the melt coating surface of the gasifier under the high temperature environment in the gasifier to form a uniform melt film.
