Acid -base regenerating unit of quick continuous type, can be fast the concentrated and continuous type ejection of compact, avoided that the membrane increases the weight of the contact scar with continuouslying, the feed liquid is rotten and the acid -base regenerating unit of quick continuous type of the lost scheduling problem of feed liquid effective ingredient.
Description
Technical field
The utility model relates to chemical field, particularly a kind of acid-alkali regeneration device of rapid continuous.
Background technology
At present, produce in high performance pigment, need to use sodium hydroxide eluted products, take the impurity such as the sodium phosphate in product, sodium-metaphosphate and pigment out of, the alkali content of the waste lye of generation is 1-2%.If by this part direct discharging of waste water to environmental protection treatment center, in spent acid salkali waste and after, adopt traditional biochemical treatment to qualified discharge.Alkali lye a large amount of in waste water does not have efficient recovery, causes larger waste, directly enhances production cost and environmental protection pressure.
Summary of the invention
For the problems referred to above, the utility model object is to provide one can rapid concentration continous way discharging, avoids the acid-alkali regeneration device of the rapid continuous of the problems such as film continues to increase the weight of contact scar, feed liquid goes bad and feed liquid effective ingredient is scattered and disappeared.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of acid-alkali regeneration device of rapid continuous, it is characterized in that: comprise the surge tank, dehvery pump, the cartridge filter that are connected successively by feed pipe, also comprise the membrane separation unit that at least two-stage and feed pipe are connected in parallel, every one-level membrane separation unit comprises recycle pump, membrane module, and the dialyzate outlet of membrane module in every one-level membrane separation unit is connected with regeneration pond; The concentrated solution outlet of the membrane module in every one-level membrane separation unit connects feed pipe; And the feed pipe between the feed pipe place that is connected with feed pipe junction and concentrated solution outlet of the recycle pump of every one-level membrane separation unit is provided with automatic ratio variable valve; Membrane element in described membrane module is nanofiltration membrane.
Preferably, described nanofiltration membrane is acid and alkali-resistance and high temperature resistant nanofiltration membrane.
Preferably, described acid and alkali-resistance and high temperature resistant nanofiltration membrane are section's formula (KOCH) acid and alkali-resistance and high temperature resistant nanofiltration membrane.
Adopt technique scheme, the acid-alkali regeneration device of rapid continuous described in the utility model, the beneficial effect had is:
1) durable acid and alkali-resistance and high temperature resistant nanofiltration membrane, preferably adopt the high chemical stability nanofiltration membrane of KOCH, acid and alkali-resistance and high temperature resistant nanofiltration membrane, can adapt to the requirement of harsh chemical environments; Effective to spent acid, waste frying oil, COD interception rate is more than 60%, and total phosphorus interception rate is more than 80%;
2) multistage high speed inner loop mode, can reach concentrating and separating requirement fast, improves enterprise work efficiency, reduces enterprise operation cost;
3) input and output material of continous way, reduces the feed liquid residence time, the problems such as feed liquid is rotten, effective ingredient is scattered and disappeared that effectively prevent overstand from causing.
Accompanying drawing explanation
Fig. 1 is the acid-alkali regeneration device schematic diagram of rapid continuous described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the acid-alkali regeneration device of rapid continuous described in the utility model, comprise the surge tank 11, dehvery pump 13, the cartridge filter 14 that are connected successively by feed pipe 12, the first step membrane separation unit 15 that two-stage and feed pipe 12 are connected in parallel and second stage membrane separation unit 16, first step membrane separation unit 15 comprises recycle pump 150, membrane module 151, second stage membrane separation unit 16 comprises recycle pump 160, membrane module 161, and the dialyzate outlet of membrane module in every one-level membrane separation unit is connected with regeneration pond 18; The concentrated solution outlet of the membrane module in every one-level membrane separation unit connects feed pipe 12; And the feed pipe between the feed pipe place that is connected with feed pipe junction and concentrated solution outlet of the recycle pump of every one-level membrane separation unit is provided with automatic ratio variable valve 17; Membrane element in described membrane module is nanofiltration membrane, and preferred nanofiltration membrane is the acid and alkali-resistance of acid and alkali-resistance and high temperature resistant nanofiltration membrane, particularly KOCH and high temperature resistant nanofiltration membrane.
During concrete use, after pending feed liquid enters into surge tank, open operated pneumatic valve, automatic ratio control valve opening is adjusted to 50%, then open dehvery pump and recycle pump successively.Now, feed liquid is transmitted across cartridge filter via dehvery pump and carries out elementary interception filtration, then it is concentrated to enter the circulation of first step membrane separation unit through recycle pump, and the acid & alkali liquid that concentrating and separating goes out directly reclaims; Dehvery pump continues to supplement feed liquid, then it is concentrated to enter the circulation of second stage membrane separation unit via recycle pump, and the acid & alkali liquid that concentrating and separating goes out directly reclaims; Last concentrated solution directly discharges; If the soda acid rate of recovery is low, membrane sepn progression can be increased or regulate proportion adjustment valve opening and increase pump flow.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
