Description

A kind of processing system of waste emulsified mixture

Technical field

The utility model relates to field of industrial waste water treatment, more particularly to a kind of processing system of waste emulsified mixture.

Background technique

Emulsion is mainly made of mineral oil, water, other additives, mainly risen in process of metal working lubrication, cooling, The effects of antirust.Occur rotten after long-time use and becomes waste emulsified mixture.Waste emulsified mixture is a kind of intractable industrial wastewater, And be hazardous waste, chemical stability and pollutional load are high.In emulsifying liquid waste water oil quality at concentrations up to 15000~ 20000mg/L, COD are up to 18000~35000mg/L, and BOD is up to 5000~10000mg/L.For improve emulsion performance, usually In use, the additive of addition has: oiliness additive, EP agent, rust-inhibiting additive, mildewproof additive, anti-bubble Foam additive etc., so that emulsion ingredient is extremely complex, processing difficulty is increased.

Currently, waste emulsified mixture treatment process has:

1. physical-chemical process+biochemical process: the method is low suitable for concentration of emulsion used, the big place of water；

2. physical-chemical process+absorbing process: the method is suitable for most of emulsions.Advantage is strong applicability, easy to operate；

3. physical-chemical process+film filter: the method is a kind of current domestic emerging technique, is suitable for most of emulsification Liquid.Advantage is that effluent quality is good, and management is easy.

But physical-chemical process needs to add strong acid, sodium, magnesium, calcium salt, alcohol, ethers organic matter etc. in waste emulsified mixture, it is right Emulsion is decomposed, to realize water-oil separating.Although such technique can reach water-oil separating purpose, can produce in the process Raw unpleasant poisonous gas and new oxide, the security risk for aggravating acid are larger.It is undesirable to exist simultaneously effect, clear liquid is slightly Muddy, the problems such as solid-liquid can not separate, process system limitation is strong, risk is big.Treatment process 1. the shortcomings that also reside in: it is primary High investment, operational management is relative complex, requires operator high.Treatment process 2. the shortcomings that also reside in: carbon leaching material It is needed to change after adsorption saturation, operating cost is caused to increase.Treatment process 3. the shortcomings that also reside in: one-time investment is big, concentration Liquid is difficult with backwash water, and fenestra easily blocks.

Therefore, a kind of new processing system is developed, water-oil separating, solid-liquor separation, Liquid liquid Separation are effectively handled, to useless cream The protection of the processing and environment of changing liquid is of great significance.

Summary of the invention

The technical problem to be solved by the utility model is to provide a kind of processing system of waste emulsified mixture, which was used Cheng Zhongwu security risk does not generate unpleasant poisonous gas in emulsion decomposable process；The multistage membrane separation technique used goes out Water water quality is good, and management is easy；Process system use flexibly moves, online processing waste liquid, before having the application of good market Scape.

The utility model provides a kind of processing system of waste emulsified mixture, including the connected breaking device of successively sequence, admittedly Liquid divides curette, primary filter, adsorption filter and overclocking vibration film；

The breaking device for adding demulsifier thereto；

The solid-liquid divides curette for tentatively removing the solid impurity for floating on waste emulsified mixture surface；

The waste emulsified mixture that the primary filter is used to remove solid carries out primary filter；

The adsorption filter is for adsorbing the oxygen consumption microorganism in emulsion, pigment；

The overclocking vibration film is for for re-filtering to primary clear liquid.

Further, the primary filter includes dross scaler and filter press.

It is less than 300mg/L by the clear liquid COD that the utility model is handled, has reached three class standard of sewage discharge, it is dense Contracting liquid can be evaporated by evaporator, and waste emulsified mixture is thoroughly refined into clear water

Beneficial effect

Without security risk in the utility model use process, unpleasant toxicity gas is not generated in emulsion decomposable process Body；The multistage membrane separation technique effluent quality used is good, and management is easy；Process system use flexibly moves, online processing is given up Liquid has good market application prospect.

Detailed description of the invention

Fig. 1 is the schematic diagram of the utility model.

Specific embodiment

The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen It please the appended claims limited range.,

Embodiment 1

As shown in Figure 1, the present embodiment is related to a kind of processing system of waste emulsified mixture, including the connected demulsification dress of successively sequence It sets, solid-liquid divides curette, primary filter, adsorption filter and overclocking vibration film；

The breaking device for adding demulsifier thereto；

The solid-liquid divides curette for tentatively removing the solid impurity for floating on waste emulsified mixture surface；

The waste emulsified mixture that the primary filter is used to remove solid carries out primary filter；

The adsorption filter is for adsorbing the oxygen consumption microorganism in emulsion, pigment；

The overclocking vibration film is for for re-filtering to primary clear liquid.

Further, the primary filter includes dross scaler and filter press.

The processing system application method of the present embodiment is as follows:

(1) waste emulsified mixture is under vacuum state and is heated to 55-65 DEG C, demulsifier is added into breaking device, decomposed Additive in waste emulsified mixture；
