Smoke exhaust system for melting combustion of secondary aluminum and working method of smoke exhaust system

Abstract

The invention belongs to the technical field of secondary aluminum production, and relates to a smoke exhaust system for melting combustion of secondary aluminum and a working method of the smoke exhaust system. The system comprises an equipment body and a water tank, wherein the water tank is located above the equipment body; a first water outlet of the water tank is connected with a first water inlet of the equipment body through a water pipe; a feeding port is formed in the water tank; a stirring device is installed in the water tank; a first cavity is formed in the equipment body; the interior of the first cavity is divided into a spraying chamber and a dust removal chamber through a partition plate; the spraying chamber communicates with the dust removal chamber through a first gas inlet; a pressurizer is installed in the first water inlet; a water spraying plate is installed at the top of the spraying chamber; water spraying openings are evenly formed in the water spraying plate; a second gas inlet is formed in the left side of the spraying chamber; a second water outlet is formed in the bottom of the spraying chamber; a plurality of dust removal plates are installed in the dust removal chamber; a gas outlet is formed in the right side of the dust removal chamber; and a second water inlet is formed in the left side of the water tank.

Description

technical field [0001] The invention belongs to the technical field of secondary aluminum production, and relates to a secondary aluminum melting combustion smoke exhaust system and a working method thereof. Background technique [0002] Recycled aluminum is aluminum ingots that meet the requirements of various standards and are produced by smelting and preparing recycled aluminum scrap parts or scraps and scrap aluminum wires in the process of producing aluminum products as the main raw materials. This kind of aluminum ingot adopts recycled waste aluminum, which has lower production cost, and it is the reuse of natural resources, which has strong vitality, especially in today's rapid development of science and technology and continuous improvement of people's living quality, the product update The frequency of replacement is accelerating, and the recycling and comprehensive utilization of waste products has become an important issue for the sustainable development of human ...

AI Technical Summary

Problems solved by technology

The following gas pollutants may exist in the secondary aluminum industry, CO, CO 2 , NO X , SO 2 , HCl, HF, hydrocarbons and volatile metal oxides or volatile metals, there may be chlorine gas, etc. Of course, not all components are harmful, but most of them will have a greater impact on the environment. Some may endanger the lives of workers

[0005] At present, most of the smoke exhaust devices are to discharge the exhaust gas after being treated by different devices. The operation is troublesome, the floor area is large, and the exhaust gas treatment is not thorough.
