Abstract

Disclosed is a method and device for melting and refining motherboards and metal wastes, comprising: a primary furnace combusting at a lower temperature for burning and melting the metal parts in the motherboards, computer peripheral equipment, cables and metal wastes, for separating non-metal parts including flammable (such as plastic) and non-flammable (such as glasses) materials, and for discharging toxic gases (Dioxin) generated during combustion of the plastic to another combustion chamber to re-combust the gases for at least one more time at a lower temperature to reduce concentration of the toxic gases, and for discharging the high temperature combustion gases to a melting furnace for melting and refining the metals, followed by using a shower tower to cool and neutralize acids in the remaining gasses. In case of tempering, external air may be introduced through an externally connected air valve to speed up the temperature reduction. An additional water tower may be used to perform washing such that particles floating the exhaust may be absorbed by a cloth tube (filter band) to be cleansed by water. A blower is connected between the shower tower and water tower, so as to introduce (pressurized air) to stop second tempering, speed up temperature reduction and exhaust discharging, to thereby discharge clean air.

Description of the invention (l) < Invention of the invention " refers especially to quality, and can use the rest of the hot melt smelting method and < In the past, with the popularization of science and brain, both motherboards and electrical objects are not applicable to A dioxin was produced during an incinerator. However, most of the waste incinerator temperature and time, the burning temperature and the toxic substances have incomplete combustion: incomplete combustion, environmental pollution, 4

Evil changes, as well as the increase in the amount of personal electrical waste) and discarded computers. As a result of the above-mentioned disposal, destruction, and decomposition, which are more incinerated, the plastic materials on general gold are burned into a huge environmental protection load. The device is continuously being researched and developed. In the technical literature, the traditional waste incineration action, its combustion needs or changes, and the composition is arbitrarily changed, and after burning, it is easy to produce boards, cables, etc.), it is easy to waste. Leakage of toxic exhaust gas will further reduce the beauty of the environment. The technical field of this invention is related to the main board and the five wastes—refinable useful substances that can be effectively separated from metals and plastics in addition to burning plastics. . Technology > Technological progress has caused people to live in a variety of waste hardware (including the brain of the metal, edge equipment, line mirrors and other similar features, that is, it is not easy to recycle the way of burying, if the temperature is easy to make the motherboard or waste, etc. Toxic exhaust gas is often in the form of various types of incinerators that have been disclosed or other patents that are implemented in a single furnace body.

The above-mentioned residue ash can be subjected to a "solidification treatment" step 1 1 2 and an appropriate amount of lime material (white stone powder) is added to condense. The hard building materials are formed, and the metal is placed in a furnace 2 10. The toxic exhaust gas (dioxin) generated when the plastic materials are burned is introduced into a secondary combustion chamber 2 0 2 for the " "Second recombustion" step 103, decomposing the toxic exhaust gas at a higher combustion temperature (approximately 1300 ~ 1 400 ° C), and repeatedly introducing the toxic exhaust gas into a The third combustion chamber 203 performs the "third recombustion" step 104 until the toxic exhaust gas is decomposed to a concentration that meets the standard, and during this time, part of the exhaust gas that is burned to the standard concentration can be introduced into the above refining Furnace 210 performs the "melting" step 113, heating the furnace 2 1 0 with its high temperature to melt the metal, and the remaining exhaust gas is directed to a first sprinkler tower 2 0 4 to perform the "first cooling" step 105. The temperature of the exhaust gas is initially reduced by using the atomized water gas, and then introduced into a first sprinkler tower 2 05,
