Method for smelting main machine plate and waste hardwares and its equipment

Abstract

The present invention relates to a method for smelting host machine board and waste hardwares and its equipment. It utilizes a main furnace body to melt the metal portion of host machine board, peripheral equipment of computer, cable and waste hardwares by using lower temp. and adopting first combustion, and can make the non-metal portions of inflammable material (for example plastics) and non-inflammable material (for example glass) be separated after they are combusted. The noxious waste gas (Daiaoxin) produced by combusting plastics can be led out, and fed into another combustion chamber to make the waste gas undergo the process of high-temp. secondary combustion so as to reduce concentration of said noxious waste gas. It also provides other equipment of water washing tower, etc. and other steps.

Description

technical field [0001] The invention relates to a method and device for smelting motherboards and waste metals, in particular to a method that can effectively separate metals, combustible and non-combustible non-metallic substances, and can eliminate toxic waste gas (dioxin) produced when burning plastics , and use the residual heat to smelt useful substances to achieve the smelting method and device of the gas emission meeting the environmental protection requirements. Background technique [0002] With the change of people's living style caused by the advancement of science and technology, and the popularization of personal computers, various waste metals (waste containing metal) and discarded computer motherboards, computer peripheral equipment, cables, etc. have increased in large quantities. One common feature is that it is not easy to recycle, destroy and decompose, so it is not suitable for general landfill treatment. If it is incinerated, the temperature of the ordin...

Problems solved by technology

[0002] With the change of people's living style caused by the advancement of science and technology, and the popularization of personal computers, various waste metals (waste containing metal) and discarded computer motherboards, computer peripheral equipment, cables, etc. have increased in large quantities. One common feature is that it is not easy to recycle, destroy and decompose, so it is not suitable for general landfill treatment. If it is incinerated, the temperature of the ordinary incinerator will easily cause the plastic material on the main board or waste hardware to burn. Toxic waste gas such as dioxin is produced, which often forms a huge load on environmental protection

[0003] For this reason, various types of incinerator devices have been continuously researched and developed. However, in most patents or other technical documents that have prior rights, traditional waste incinerators mostly perform related incineration actions with a single furnace body. The temperature and time of combustion are fixed, and the combustion temperature and time cannot be changed arbitrarily according to actual needs or changes, so that it is applied to substances with complex composition and easy to produce toxicity after combustion (such as: the above-mentioned computer motherboards, cables, etc.) , it is easy to have incomplete combustion and produce toxic waste gas (dioxin). Incomplete combustion of waste is not conducive to subsequent treatment. Leakage of toxic waste gas will cause environmental pollution, which greatly reduces the original intention of incineration for environmental protection waste treatment.
