Mixed plastic treatment process and water treatment system

Abstract

The invention relates to a mixed plastic treatment process. The mixed plastic treatment process comprises the following steps of primarily screening original garbage, and screening out mixed plastic garbage; conveying the mixed plastic to a crushing and dust removal system, and removing the mixed dust and soil particles in the mixed plastic; conveying the crushed plastic to a plastic winnowing system for sorting, conveying the high-quality plastic flowing out of a upper outlet of the plastic winnowing system to scrubbing equipment, conveying the scrubbed plastic to a washing tank for washing,and conveying a small amount of inferior plastic which is suspended in water and immersed into the water bottom to a centrifugal device to be dehydrated and dried by using a scraper; conveying the plastic floating on the water surface to a rinsing circulating tank, and rinsing the plastic; dewatering and drying the rinsed plastic to obtain the raw materials of the renewable plastics so as to complete the recovery treatment of the mixed plastics. On the whole, the mixed plastic treatment process and the water treatment system has the advantages of being reasonable in design, clear in classification, clean in cleaning, small in water consumption and free of pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of plastic recycling, and in particular relates to a mixed plastic treatment process and a water treatment system. Background technique [0002] As a new type of material, plastic products have the advantages of light weight, waterproof, durable, mature production technology, and low cost. They are widely used all over the world and show a growing trend year by year. my country is one of the top ten plastic product production and consumption countries in the world. , these easy-to-use and low-cost plastic products bring a lot of convenience to people's lives, but these plastic products are often discarded after use, causing "white pollution", forming environmental hazards, and becoming a huge environmental problem. , A large number of plastics are recycled by landfill or incineration, resulting in a huge waste of resources and environmental pollution. With the rise of global crude oil prices, the price of plas...

[0002] As a new type of material, plastic products have the advantages of light weight, waterproof, durable, mature production technology, and low cost. They are widely used all over the world and show a growing trend year by year. my country is one of the top ten plastic product production and consumption countries in the world. , these easy-to-use and low-cost plastic products bring a lot of convenience to people's lives, but these plastic products are often discarded after use, causing "white pollution", forming environmental hazards, and becoming a huge environmental problem. , A large number of plastics are recycled by landfill or incineration, resulting in a huge waste of resources and environmental pollution. With the rise of global crude oil prices, the price of plastic products, one of petroleum derivatives, naturally also rises, and the recycling of waste plastics is also being used. The primary position is mentioned, and the recycling and reuse of waste plastics has been widely adopted by modern chemical enterprises; therefore, it is necessary to provide a mixed plastic treatment process and water treatment system with clear classification, cleanness, low water consumption, and no pollution to the environment
