A waste plastic recycling system based on solar energy integration technology

Abstract

The invention discloses a waste plastic regeneration system based on a solar energy integration technology. The system comprises a disc type heat collection tracking device used for collecting solar energy, a thermal storage insulation device used for storing heat energy, and a spiral heating and mixing device, wherein the disc type heat collection tracking device is connected with the thermal storage insulation device in series by a heat storage circulating pipeline; the thermal storage insulation device is connected with the spiral heating and mixing device in series by a heat supply circulating pipeline; a PC controller is respectively connected with the disc type heat collection tracking device, the thermal storage insulation device and the spiral heating and mixing device by a lead. The heat-conducting medium in the thermal storage insulation device is transmitted into an external heating circulation pipeline and a hollow screw shaft by a pipeline pump through the heat supply circulating pipeline, and the waste plastic fed into a shell can be heated by a heat exchange way. According to the system, the solar energy is used for replacing electric energy and fire coal for heating, so that the waste plastic regeneration cost is lowered, and the environmental pollution can be alleviated.

Description

technical field [0001] The invention relates to auxiliary equipment for solar heat collection and a waste plastic regeneration system, in particular to a waste plastic regeneration system based on solar energy integration technology. Background technique [0002] The development of the plastics industry has brought great benefits to mankind, but it has also left behind endless "white pollution". Because waste plastics are not easy to age and degrade at room temperature, white pollution is increasing day by day, causing serious damage to the ecological environment. The recycling of waste plastics has always been the focus of people's attention and research. The most widely used and most mature processing method in the recycling of waste plastics is to heat, melt and knead waste plastics to produce plastic particles. At present, the heating, melting and mixing of waste plastic recycling equipment mainly adopts electric heating and coal-fired heating. The shortcomings of the e...

AI Technical Summary

Problems solved by technology

At present, the heating, melting and mixing of waste plastic recycling equipment mainly adopts electric heating and coal-fired heating. The shortcomings of the existing technology are that the electric heating method consumes a lot of energy, and coal-fired heating has solid waste residue pollution and air pollution. ; and the cost of electric heating and coal-fired heating is high
