Description
Technical field
The utility model relates to the three-phase separating device of a kind of gas, liquid and solid mixture, is specifically related to a kind of three phase separator that is used for the overcritical separation of printed substrate.
Background technology
Since the twentieth century, the develop rapidly of information technology and electronics industry, make that the range of application of electronic product is more and more wider, kind and quantity surge, and the update cycle of electronic product is shorter and shorter, a problem will be placed in front of us inevitably, the generation of electron wastes in a large number that Here it is.China is the production of household electrical appliance and uses big country.From 20th century the mid-80, household electrical appliance enter family in a large number, and the social recoverable amount of refrigerator reaches 1.1 hundred million at present, and 1.5 hundred million of washing machines, television set are especially up to 3.2 hundred million.Because all met or exceeded service life the service life of these large household appliances, thereby by social recoverable amount measuring and calculating, annual about 4,000,000 of the refrigerator that a few years from now on will enter regeneration period, 5,000,000 of washing machines, 5,000,000 of television sets.China's household electrical appliance upgrade to be scrapped and will enter the peak.Printed substrate (PCB) is the basis of electronics industry, is indispensable vitals in each electronic product, from computer, television set to electronic toy etc., almost all has printed substrate to exist in all electronic products.Therefore, the recycling of PCB has critical role in the processing of electron wastes.
The electronic devices and components that can re-use and the economic worth of precious metal are to support the economic base that the electron wastes industrialization is reclaimed, all precious metals all are used to make electronic devices and components, and electronic devices and components all concentrate on the circuit of PCB, therefore the industrialization of PCB recycling is an economic feasibility, is the breach of electron wastes industrialization recycling.This point worldwide obtains common recognition, and the U.S., Germany, Japan, Singapore have all set up the factory of special recovery PCB, have obtained high economic well-being of workers and staff and environmental benefit.But PCB is substrate with the thermosetting resin, how to exist with the coating form, and metal is difficult to separate.The recovery and treatment method of the domestic and international waste printed circuit board that uses has pyrogenic process recovery, hydrometallurgic recovery, bioanalysis to reclaim at present, machinery reclaims etc., and new technology is also in continuous Application and Development.Supercritical technology is exactly wherein a kind of.
Complicated polymer such as printed substrate, small-sized magnetic head and small inductance contain a large amount of metals in the electron wastes, as copper, zinc, aluminium, iron, nickel, tin and a certain amount of gold, silver, platinum and rare element selenium etc., tenor is higher than ore far away, with respect to from raw ore, refining, the recycling expense can reduce by 20～50%, produce the refuse amount and can reduce 15～90%, economy and environmental benefit are considerable.Yet metal exists with the coating form usually in the electron wastes, can't effectively separate with conventional meanses such as machinery, electromagnetism, chemical methodes.
Utilize supercritical technology, substrate is carried out swelling, makes its fluidization, and metal keeps solid-state, in three phase separation, reach complete invisible separation of substrate and metal, metal recovery rate height, and non-secondary pollution.Supercritical fluid technique itself is ripe and be used widely.When fluid temperature surpasses specific critical point with a pressure that bears, promptly enter supercriticality, density and liquid are close, and viscosity and gas are seemingly.Fluid has extremely strong solubility property under supercriticality, even can make the polymeric substrates fluidization, and gas and organic solubility are distal to liquid state, and inorganic matter is then opposite, thereby realizes and thoroughly the separating of metal.In addition, near super critical point, can control the solubility of substrate very easily by changing supercritical temperature and pressure, the restriction of mass transfer rate has also been broken in the increase of solubility, thereby greatly improved the speed of reaction, effectively metal and the substrate in the separate complex polymer.The main characteristic of this technology is multidisciplinary intersection with comprehensive, and the method for utilizing supercritical fluid to separate realizes separating fully of plastics and metal in the electron wastes, improves the rate of recovery of metal, and that realizes that electron wastes reclaims cleans.
But present supercritical reaction device is not to separate and design at printed substrate, and three phase separator wherein often is unsuitable for the separation of metal dust, metal fragment, solvent, gas.The application has developed the three phase separator of special printed substrate at this situation.
