Compared with the prior art, the purification device has the advantage that the treatment cost is lower, the market price of CaCo3 is **-* yuan/ton, 2.3 tons of CaCo3, the same dosage as that of H2SO4, is used for the production of one ton of expansible graphite materials, and plus the cost of power consumption and manual work, the unit cost is around ** yuan, which is seven times lower than that of alkali treatment and more than 5 times lower than that of quicklime treatment, so enterprises producing expansible graphite materials can afford the cost of sewage neutralization treatment.
Description
Technical field
The utility model relates to a kind of graphite production unit, particularly a kind of expansible black lead wash water purifying processing device.
Background technology
Producing expansible black lead, is with natural flake graphite and H
2SO
4(vitriol oil) or HNO
3Strong oxidizers such as (nitric acid) drops into special reactor by formula rate and carries out the acid group intercalation, again through washing, dehydration, dry getting final product.No matter used which kind of acids chemical products carries out intercalation, and after washing, it is acid that its wash water all is, and acidity value can reach PH=1, all can not directly discharge, otherwise can serious environment pollution and water source.So must carry out neutralizing treatment, make PH=6 ~ 7 just can reach discharging standards.
In producing expansible black lead raw material process, owing to consume H
2O (water), H
2O
2(hydrogen peroxide), H
2SO
4Chemical products amounts such as (vitriol oils) is bigger, and the sour water amount of formation is also very big, and it is an important difficult problem that wash water is handled.Usually the sour water neutralizing treatment is used solid alkali or liquid alkali, carries out acid-base neutralisation and handles, and perhaps uses unslaked lime, carbide slag neutralizing treatment.If use the bases neutralizing treatment, because of bases produce market price height, the neutralizing treatment cost is very high.2.3 tons in the sulfuric acid of market one ton of expansible black lead raw material need concentration 98%, about 80 tons of flushing water consumptions, 2.3 tons of the soda ash of neutralizing treatment sewage need content 99.9%, 1800 yuan/ton of market prices add the electricity charge, labour cost etc., unit cost is up to more than 4000 yuan/ton.If use unslaked lime, carbide slag neutralizing treatment, the sewage disposal of the one ton of raw material in market need consume 4 ~ 6 tons, and the processed in units expense also reaches more than 3000 yuan/ton.Also produce a large amount of precipitation slags simultaneously, form secondary pollution.With above-mentioned traditional neutralizing treatment method processing cost expense height not only, also there is a common problem, be that bases product or unslaked lime input amount in neutralizing treatment is on the low side, it is acid that sewage still is, and PH＜5 are if input amount is on the high side, sewage is alkalescence, PH〉7, be difficult in actually operating the neutrality of control water, all can not directly discharge.Therefore, the wash water neutralizing treatment is to perplex the great difficult problem that expansible black lead is produced for a long time.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides a kind of expansible black lead wash water purifying processing device, can reduce the cost of sewage purification, improves the effect of sewage purification, reduces environmental pollution.
The purpose of this utility model is achieved in that a kind of expansible black lead wash water purifying processing device, comprises the neutralizing treatment pond, and the sour water pipe is communicated with the neutralizing treatment pond, and top, neutralizing treatment pond also is provided with the neutralization material and throws in tube seat.
Described neutralizing treatment also is provided with wash pipe in the pond, and an end of wash pipe is positioned at the neutralizing treatment pond, and wash pipe is provided with water pump.
Described neutralizing treatment also is provided with circulating pipe in the pond.
Described neutralization material is thrown in tube seat and is connected with the equipment of carrying water-ground limestone.
Described neutralizing treatment pond is a plurality of, and correspondingly sour water pipe, wash pipe and circulating pipe also are a plurality of.
A kind of expansible black lead wash water purifying processing device that the utility model provides, by the neutralization material input tube seat be communicated with the water-ground limestone handling equipment is set above the neutralizing treatment pond, in having reduced and cost, good purification, practical.Reached desirable decontamination effect improving.
Compared with prior art advantage of the present utility model is: the one, and the processing costs cost is low, CaCO
3The market price is 140 ~ 180 yuan/ton, produces one ton of expansible black lead raw material and drops into 2.3 tons (with H
2SO
4Consumption is identical, and this is the conclusion that repetition test detects), add power consumption, expense such as artificial, unit cost is about 600 yuan, descending 7 times than handling with bases, descend more than 5 times than handling with unslaked lime, is that enterprise produces the sewage neutralizing treatment cost that the expansible black lead raw material can bear.
The 2nd, simple to operate, particularly control the neutrality of water easily.After sewage enters the neutralizing treatment pond, directly incite somebody to action CaCO
3Put in the pond and immediately vigorous reaction can take place, if injected volume is few, when water is acidity, strengthen injected volume again, water can not be alkalescence, remains in the pond CaCO
3Can react with sour water again, can not form waste.Also available noncorrosive pump extracts that water stirs dashing in the pond in the pond, allows it fully react.Chi Zhongshui can remain neutrality after being neutrality, and is too much, CaCO
3Can treat to react with sour water more next time, also can not waste.
The 3rd, neutralizing treatment water can extract recycle again.After the reaction, treat the precipitation clarification in the pond, its clear water is drawn back the workshop recycle with pump, can significantly reduce water loss, and namely the conserve water resource has reduced the water consumption production cost again.
The 4th, throw out is collected the byproduct for treatment that can be used as enterprise after the drying in the pond, for example is used for the production of material of construction, can not form secondary pollution.CaCO
3With the H in the sewage
2SO
4After the reaction, be decomposed into CaSO
4(calcium sulfate) and CO
2(carbonic acid gas), H
2O (water).Calcium sulfate is a kind of general byproduct of having many uses, not only can be used for material of construction and cement, also can be used for industries such as rubber, plastics, fertilizer, agricultural chemicals, paint, weaving, medicine, papermaking, chemical industry, industrial art, culture and education, metallurgy, very high value of exploiting and utilizing is arranged.
The 5th, sewage does not discharge substantially, is conducive to environment protection.
