Description
Technical field
The present invention relates to a kind of recycle devices of waste liquid of concentrated base containing aluminium, can be used for pot mould to aluminum profile production process
Waste alkaline solution, the aircraft aluminum of (also referred to as boil mould or steep mould) waste liquid, aluminum profile and Aluminum Plate and Strip in process carry out lye
The milling waste liquid generated during chemistry milling is recycled, and the alkali collection for belonging to environment protection field utilizes device.
Background technique
First working procedure of the aluminum profile in production, the profile of shape required for being exactly squeezed into aluminium bar.It is needed when extruding
Use mold, and these molds need after the completion of extruding by aluminium removal remaining in mould cavity, using piece aqueous slkali or
Liquid alkaline (NaOH) impregnates.Remaining aluminium generates kickback and heat release in these high-concentration sodium hydroxide solution and mould cavity,
Metallic aluminium can be dissolved gradually in mold, so that mold becomes completely, in order to be reused.This process is referred to as
" stewing mould " also referred to as " boils mould or bubble mould ".
Aluminium content in the lye of this processing mold can gradually rise, when the aluminium that sodium hydroxide and metal reactive aluminum generate
Sour sodium is further continued for dissolving more aluminium, the solvability of sodium hydroxide solution can be decreased until when lye China is more and more
It completely loses.
When general fluting, mould liquid naoh concentration is stewed between 200-300g/L, with the continuous increasing of dissolution metallic aluminium
More, aluminium ion concentration rises, and the speed for dissolving aluminium constantly declines, and when aluminium ion reaches 50-70g/L, pot mould speed is too slow, needs
Slot forms waste liquid.Stewing mould waste liquid is a kind of very high waste liquid of alkalinity, such as without processing, it will generate biggish environment
Pollution.
Similarly, in many aluminum profiles and the process of surface treatment of Aluminum Plate and Strip, there is " alkaline etching " link.When molten in alkaline etching slot
After having solved excessive metallic aluminium, the aluminium composition in tank liquor is excessively high, and tank liquor must discharge, and forms waste liquid.
Similarly, in the lye chemistry milling of aircraft aluminum, when aluminium ion concentration is excessively high in lye, also will be unable to using,
Generate waste liquid.
Currently, more commonly processing waste water mode mainly has acid-base neutralization and aluminium hydroxide partial crystallization etc., but this both at home and abroad
There is various deficiencies, especially processing cost are excessively high for a little modes.The waste liquid of concentrated base containing aluminium is a kind of higher waste liquid of alkalinity, is used
Common acid-base neutralization mode not only wastes a large amount of acid, can also generate the waste residue and waste water of flood tide.With aluminium hydroxide partial crystallization
When mode is handled, not only invest huge, and aluminium ion removal rate is only capable of reaching 50% or so, and will cause pipeline, valve and
Partial crystallization slot serious scale, it is very troublesome.Most of aluminium processing enterprise will not only expend a large amount of piece alkali use cost, and
And a large amount of concentrated base waste water is handled, form the waste of huge social resources.
Summary of the invention
The purpose of the present invention is to provide a kind of devil liquor recoveries of concentrated base containing aluminium to utilize device, to solve existing technological deficiency
With inaccessiable technical requirements.
To achieve the above object, the invention provides the following technical scheme: including waste collection bucket, diaphragm pump, filter, stirring
Mix reaction cone tank, lime powder medicine-adding bin, powder-suction, corrosion-resistant filter press and clear liquid reuse bucket.The waste collection bucket
Top is equipped with corrosion resisting diaphragm pump, and waste liquid is entered after filter 1 filters to continue to be pumped by diaphragm pump by pipeline to be stirred to react
In cone tank, the lime powder in medicine-adding bin is pumped into and is stirred to react in cone tank by powder-suction, while originally water solenoid valve is logical
Electricity water inlet.To after the reaction was completed, the mixture being stirred to react in cone tank is separated by solid-liquid separation by filter press, that isolates is limpid
Lye, which enters after clear liquid reuse bucket is collected, to be recycled；The solid matter isolated is that high-quality Industrial chemicals water closes calcium aluminate, dress
Raw materials for production after bag collection as water purification agent aluminium polychloride (a kind of water purification agent being widely used) are used.
Preferably, corrosion resisting diaphragm pump is installed, diaphragm pump enters waste liquid by pipeline above the waste collection bucket
Filter 1 continues to be pumped into after filtering to be stirred to react in cone tank, and each section is connected by pipeline.
Preferably, the lime powder in medicine-adding bin is pumped into and is stirred to react in cone tank by the powder-suction, while originally
Water solenoid valve, which is powered, intakes, and each section passes through pipeline and connects.
Preferably, the mixture being stirred to react in cone tank is separated by solid-liquid separation by the filter press after completion of the reaction,
The limpid lye isolated, which enters after clear liquid reuse bucket is collected, to be recycled；The solid matter isolated is high-quality Industrial chemicals water
Calcium aluminate is closed, pack is collected.Each section is connected with pipeline.
Compared with prior art, beneficial effects of the present invention are as follows:
1. the device of the invention can remove 95-in waste liquid compared with the general waste liquor treatment equipment of concentrated base containing aluminium
100% aluminium ion, speed is fast, at low cost, easy to operate, waste liquid 100% is recycled, zero-emission.Reduce 90% or more
Alkali consumption, the aluminate hydrates sodium solid separated can be used as good industrial chemicals and be used, achieve many things at one stroke.
