Description
Technical field
The invention belongs to scrap glass resource technology fields, and in particular to a kind of novel glass refuse processing method.
Background technique
With the rapid development of science and technology with the increasingly raising of living standards of the people, glass is widely used in house and builds
It builds among the daily life with the people.It has also been inevitably generated many glass wastes at the same time, has been formed a large amount of useless
Glass.For example, 5%~25% leftover bits can be generated under glass normal production conditions；Under non-normal condition, due to life
The loss of the cullet and glassware of unstable generation in transport and use process is produced, quantity is difficult to estimate.In addition people
In daily life the glass packaging Bottle & Can abandoned and the windowpane fragment smashed etc. be also one of the source for generating cullet.According to
Statistics, the cullet that China generates every year have 10,400,000 t, account for the 5% of solid waste total amount.However, being difficult to lead to post-consumer glass
It crosses Natural Circulation and general physico-chemical process is decomposed and handled, seriously affected ecological environment purification.This requires
Cullet is for recycling and reuse.Glass recycle in addition to reducing waste material, there are also saving raw material, it is energy saving, slow down mine
The many merits such as exploitation process.
Since the comprehensive utilization work of cullet has certain economic benefit and environmental benefit, thus countries in the world are
The work of Efforts To Develop recycling cullet.Recycling approach primarily now has following several: (1) direct circulation is sharp again
With this is concentrated mainly on glass container, such as beer bottle and pop bottle.Before the deadline, the number of its Reusability is improved, no
Utilization efficiency only can be improved, production cost can also be reduced.But the method directly recycled is confined to complete glass and holds
Device, and these glass containers have certain service life.(2) using post-consumer glass as the raw material of glass production, the party
Method can reduce the melting temperature of glass in technique, reduce the energy and save raw material.But the Glass optical deformation produced is serious,
The defects of color is deep, bubble, point, sand grains, scuffing is more, and easily broken.(3) by the life of post-consumer glass architecture engineering material
In production, such as the production of building facing material, insulation, acoustic material or various composite materials.This method save raw material,
Production cost is reduced, but processes preparation process complexity, cost is relatively high.
To guarantee that cullet continues efficiently to recycle, need to explore new cullet utilization ways, developing target market needs
New product.The present invention degrades to glass waste using hydrothermal method.By the temperature of control reaction, pressure and add
Add the content of agent, the type and concentration of adjustable products therefrom.This method is easy to operate, low in cost, is the money of cullet
Source provides new approach.
Summary of the invention
It is an object of the present invention to be directed to the limitation of existing glass refuse processing method, processing cost height, place are overcome
The problems such as managing complex process, the present invention provide a kind of easy to operate, low-cost glass refuse processing method.
Technical scheme is as follows:
A kind of method of hydrothermal degradation glass waste, the specific steps are as follows:
(1) reactant glass waste is mixed with water, is placed in reaction vessel, addition additive adjusts pH value；
(2) reactant is reacted to a period of time under given conditions；
(3) obtained product is separated.
It using the scrap glass that partial size is 20~60 mesh as reactant in step (1), takes water as a solvent, is placed in high pressure resistant, resistance to
In the reaction vessel of corrosion, for the mass values of reactant and solvent between 1:20~1:5, the additional amount of solvent is reactor body
Long-pending 20~60%.
Additive therefor is organic acid or inorganic acid in step (1), such as one in hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, acetic acid
Kind or two kinds, pH value is adjusted between 0~7, preferably pH be 2~5 between.
The reaction vessel equipped with mixture is placed in baking oven in step (2), within the scope of 150~300 DEG C, pressure exists
Within the scope of 0.48~8.58MPa, and 30~120min of heated at constant temperature with this condition, it takes out reactor and is cooled to room temperature.
Step (2) reaction optimal conditions be 200 ± 5 DEG C, pressure be 1.55 ± 0.15MPa, the reaction time be 60 ±
5min。
Separation method used in step (3) is any in filtering, complexing, precipitating, selectivity transmission or ion exchange
It is a kind of.
Glass waste is silicate glass, one of sillico aluminate glass, silicon borate glass or two kinds or more.
Reaction primary product is silicic acid, and by-product is one in chloride, sulfate, nitrate, phosphate or acetate
Kind or two kinds or more.
Present invention has an advantage that
(1) provide a kind of novel glass refuse processing method, for glass waste recycling open it is new
Approach.
(2) this method is easy to operate, low in cost.It is directly mixed using by glass waste with water, at 180~300 DEG C
30~120min of lower reaction, avoids high-temperature fusion when traditional recycling, to significantly reduce cost, has saved energy
Source.
(3) product can be used as industrial chemicals and be used.By hydro-thermal reaction, glass is degraded to silicic acid and corresponding salt
Class, such as chloride, sulfate, nitrate, phosphate, acetate.The product has certain application city as industrial chemicals
?.
