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
The invention relates to the melting method and the device thereof of a kind of motherboard and waste hardware, be meant a kind of effectively separating metal, flammable and not flammable nonmetallic substance especially, and the poisonous fume (dioxin) that produces in the time of can eliminating the burning plastics, and all the other hot melts of mat refining useful matteies, reach the melting method and the device thereof of the gaseous emission of compliance with environmental protection requirements.
Background technology
Cause the change of people's lifestyle along with scientific-technical progress, and PC is universal, various waste hardwares (metallic waste) and depleted computer main frame panel, computer peripheral equipment, cable etc. roll up, because above-mentioned waste all has a common characteristic, promptly be difficult for reclaiming, destroying and decompose, so be not suitable for the processing mode of generally burying, if handle in the burning mode, then the temperature of common incinerator easily makes the plastic material on motherboard or the waste hardware produce poisonous fumes such as dioxin when burning, often forms in the environmental protection and loads greatly.
For this reason, the incinerator device of various types continues to be studied development, yet, in the patent or other technical literature of most of rights formerly, mostly traditional waste incinerator is to implement the relevant action of burning with single body of heater, its incendiary temperature and time is all fixing, can't be according to actual needs or variation and change temperature of combustion and time arbitrarily, be applied to complicated and burning back easy toxigenous material (as: the aforementioned calculation machine host plate of combination ingredient with it, cable etc.) time, incomplete combustion and the situation that produces poisonous fume (dioxin) are arranged easily, waste combustion not exclusively then is unfavorable for follow-up processing, poisonous fume leaks and more causes the pollution of environment, so causes the original meaning of incinerating the environmental protection offal treatment to be had a greatly reduced quality.
Because common waste incinerating apparatus structure still has above-mentioned shortcoming, the contriver improves at those shortcoming researchs, and generation of the present invention is arranged finally.
Summary of the invention
The present invention aims to provide the melting method and the device thereof of a kind of motherboard and waste hardware, it mainly is to fuse this motherboard by a main furnace body with lower temperature control primary combustion, metal in the waste hardware partly, and make flammable (as: plastics) reach nonmetal separation after burning such as not flammable (as: glass), and the poisonous fume (dioxin) that is produced will burn plastics the time leads to another combustion chamber, reignition with at least higher temperatures, to reduce the concentration of this poisonous fume, and these pyritous combustion gases are exported to the smelting furnace smelting metal, then, lower the temperature and the step of acid-base neutralisation through at least one watering tower again, with in and the acidity of residual gas, again to implement a water-washing step by a water wash column, go up and wash so that the particle that swims in the waste gas is attached to stringing (strainer) with water, last then gas that should cleaning can be discharged, it can fill part and reach the environmental requirement of removing poisonous fume, and this is a main purpose of the present invention.
The melting method and the device thereof of this kind motherboard of the present invention and waste hardware, it can increase reignition number of times and follow-up in difference watering tower in the lower the temperature number of times of this poisonous fume in different combustion chambers according to objective working conditions and environmental requirement, it is used and goes up than tool elasticity, and can satisfy different actual demands, this is an another object of the present invention.
The melting method and the device thereof of this kind motherboard of the present invention and waste hardware, it can suitably import (pressurization) air admission with an air intake valve in the pipeline after the waste gas cooling, can avoid the high tempering phenomenon, lower the temperature faster and the deflated effect and reach, use the effect that reaches enhancement off gas treatment efficient, this is a further object of the present invention.
As for detailed construction of the present invention, application principle, effect and effect, then the explanation of doing with reference to following adjoint can be understood completely:
Description of drawings
