Description
Technical field
The utility model belongs to a kind of waste treatment system.Specifically, the utility model relates to a kind of industrial waste acid treatment system.
Background technology
In the modern industrial, for example non-ferrous metal metallurgy, Iron And Steel Industry, electronics change in the industries such as platinum, store battery, wlding, photovoltaic, five metals, rare earth, need carry out various processing with a large amount of acid, and produce a large amount of spent acid.Exist the concentration of a large amount of metal-salts and acid still higher in these spent acid,, waste resource again, so must recycle to it if directly discharging both can cause environmental pollution.
Yet, can not realize in actual industrial production owing to be usually used in carrying out the acid resistance of the reverse osmosis membrane of liquid waste disposal in the existing Technology, so spent acid and acid waste water are infeasible through the spissated method of reverse osmosis membrane.
In addition, existing spent acid reclaims pretreatment technology and adopts sand filtration, melt-blown filter strainer, under the situation high in the face of the spent acid foreign matter content, needs often to change silica sand, filter core.If it is adopt ceramic membrane overanxious, but impracticable in actual production process because ceramic membrane does not have acid resistance.
Moreover existing spent acid recovery processing technique has only solved sour part reuse, also has a large amount of raffinates and acid waste water to discharge, and does not have thoroughly to solve the problem of recycling.
Also have, on liquid concentrator was handled, existing general technology adopted freezing and crystallizing, and energy consumption is very high, and the salt that freezing and crystallizing comes out is inapplicable.
Hoping has a kind of treatment system to handle industrial waste acid effectively, overcomes similar problems such as the prior art cost is high, efficient is low.
The utility model content
The technical problem that the utility model will solve is a kind of treatment system to be provided, to overcome similar problems such as the prior art cost is high, efficient is low.
The utility model technical problem to be solved can be able to solve through following technical scheme:
A kind of industrial waste acid treatment system is characterized in that it comprises:
Full-automatic acidproof microfiltration equipment;
Diffusion dialysis device with said full-automatic acidproof microfiltration equipment fluid communication;
Acidproof film nanofiltration equipment with said diffusion dialysis device fluid communication; And
Vacuum salting-out evaporator with said acidproof film nanofiltration equipment fluid communication.
Said acidproof film nanofiltration equipment further forms circulation loop with said diffusion dialysis device, returning said diffusion dialysis device again through the acid solution that said acidproof film nanofiltration device processes is crossed.
Filtering material in the said full-automatic acidproof microfiltration equipment is Vilaterm or Vestolen PP 7052.
Said full-automatic acidproof microfiltration equipment is the full-automatic microfiltration equipment of TJB series.
The utility model adopts full-automatic microfiltration systems, filtering accuracy controllable precision scope: 0.03um-150um.Minimizing labor strength and saving frequent change filter core cause the cost waste.
The acidproof film nanofiltration equipment of the utility model is used to accept the acid solution of handling through said diffusion dialysis device and will return said diffusion dialysis device again through the acid solution that acidproof film nanofiltration equipment is further handled, and has reduced the spent acid residual liquid discharge.
Filtering material in the said microfiltration equipment in the utility model is Vilaterm or Vestolen PP 7052, and it realizes surface filtration, and filter core is difficult for stifled, is prone to backwash, and the blowback product is a solid slag, no longer takes to and reduces spent acid raffinate intractability in the spent acid raffinate.
Handle the residual night after the utility model reclaims spent acid through the vacuum salting-out evaporator, and the raffinate that solves after spent acid reclaims is handled problems.Adopt vacuum distillation method in addition, energy consumption is low.
Generally speaking, adopt the industrial waste acid treatment system of the utility model, can improve the spent acid recovery, significantly reduce labor strength, reduce the pretreated operation of spent acid, one step of spent acid pre-treatment can realize accomplishing.Easy handling cuts down the consumption of energy.
