Waste Refrigerator Recycling Scheme

Solution Background

With the increasing consumption of electrical products and the decreasing product life cycle, the output of electrical waste is gradually increasing, and the growth rate is increasing year by year. The impact of electrical waste on the environment has become a global problem, especially in China. As a country with relatively scarce resources, strengthening the recycling of electrical waste can not only ease the tension of resources, but also meet the needs of sustainable development of human society.
In some places, there are a large number of individual workshops for dismantling and disposing of waste electrical products. In order to pursue short-term benefits, they use primitive and backward methods such as open-air incineration and strong acid immersion to extract precious metals. The random discharge of waste gas, waste liquid and residue has caused sub heavy pollution to the atmosphere, soil and water, and endangered human health. Nonstandard disassembly and extraction of raw materials are the main causes of serious environmental pollution and human health damage caused by waste electrical products.

Solution Introduction

System Introduction

Brand: Zhihao

Introduction: the harmless treatment and resource recovery equipment for waste refrigerators is independently developed by Hebei Zhihao. It adopts the unique combination design of "pretreatment system + vertical shaft strong crusher + crushing product sorting system + foam granulation system + weighing system + dust removal system". It dilutes with large air volume and collects cyclopentane to avoid explosion. The waste refrigerator resource recovery and treatment equipment is mainly used for crushing, separating, sorting and resource recycling of waste refrigerators

Performance Advantage

All electrical components of the supporting equipment are imported brands such as Siemens / ABB / Schneider, France, and the matching cables are domestic first-line brands, which meet the national mandatory standards. The iron recovery rate of the production line is ≥ 99.5%, the plastic recovery rate is ≥ 98%, and the polyurethane foam separation rate is ≥ 97.8%.
The whole production line adopts Mitsubishi PLC automatic control, has CCTV monitoring system and big data center, can collect operation data of all equipment, has operation fault alarm function, better analyzes the operation data of the production line for the owner, calculates the operation cost, and optimizes the operation rhythm.
Prepare a nitrogen device to ensure that the alkane gas does not accumulate and explode during the operation of the crusher; Equipped with flammable gas detector; Equipped with high-sensitivity flame detector, spray device, etc., full-automatic PLC detection and control, short reaction time of spark detector, automatically start the spray device to extinguish the fire in case of fire accident;
The whole line is equipped with foam plastic collection and dust collection system. The central pulse dust collector collects the dust generated in the production process in a unified way, with an emission of ≤ 10mg / m3, which conforms to the national standard GB / z2.1-2007; Materials, dust and exhaust are conducted separately, and independent exhaust system is adopted, which is conducive to environmental protection and production safety.
