Energy-saving environment-friendly treatment system for recycling of waste metal paint buckets

Abstract

The invention belongs to the field of environment-friendly waste metal paint bucket treatment and purification and discloses an energy-saving environment-friendly treatment system for recycling of waste metal paint buckets. The system comprises an automatic feeding system, a pyrolysis system, an iron scrap recovery system, an incineration system, a waste heat utilization system, a quenching system, a deacidifying system, a dedusting system, a denitration system and a smoke discharging system. After pyrolysis treatment, sheet iron of the waste metal paint buckets enters a cooling furnace to be cooled and recovered, and other systems completely recycle waste heat. Due to adoption of recycled smoke for pyrolysis, generated NOx is greatly reduced, fuel saving is realized by complete utilization of energy, and tail gas treatment cost is reduced.

Description

technical field [0001] The invention belongs to the field of waste metal paint bucket treatment, purification and environmental protection, and specifically relates to an energy-saving and environment-friendly treatment system for waste metal paint bucket recycling. Background technique [0002] Collecting used waste paint buckets is an act to prevent them from entering the ecosystem and causing harm to the environment. Waste paint buckets contain a lot of toxic substances. If discarded at will, discarded waste paint buckets will destroy our water sources, corrode the crops and land we depend on for survival, and our living environment will face a huge threat. [0003] For the waste paint buckets produced, in the past, they were generally crushed mechanically or directly landfilled as construction waste. This treatment method cannot completely dispose of the waste paint. With the development of social economy and industrialization, especially in the construction, installat...

Problems solved by technology

[0003] For the waste paint buckets generated, in the past, mechanical crushing or direct landfilling as construction waste was generally used. This treatment method cannot completely dispose of the waste paint

With the development of social economy and industrialization, especially in construction, installation, shipbuilding and other industries, a large number of waste paint buckets are produced. The waste paint buckets produced every year not only occupy a large number of sites and warehouses, but also create certain environmental pollution. Pollution and potential safety hazards restrict the development space of enterprises

This problem has become a headache for many industries. Therefore, the task of processing waste paint buckets is very arduous, and it also affects the further expansion of the industry's business.
