The Pollution abatement technology of degreasing at present and cleaning by degreasing waste water mainly is the end treatment technology, uses the acidifying breakdown of emulsion, adds a large amount of mineral acids, regulates pH value about 2, removes grease; Use remaining grease, polymeric surface active agent and metal ion etc. in the mixed condensed gas flotation process removal waste water then; Adopt aerobic biochemical process to remove dissolved organic matter in the waste water and a spot of phosphoric acid salt etc. again; The water outlet qualified discharge.
Present application industry clearer production technology mainly contains the purification techniques, electrophoresis groove liquid electrocoating paint recovery technology of low toxicity coating technology, no nitrite-oxidizing technology, low alkali degreaser technology, low acidity rust remover technology, low zinc phosphating process agent technology, spraying cleaning water-saving technology, phosphatization tank liquor etc.But cleansing and recycling is carried out in the draining with regard to degreasing and cleaning by degreasing operation, reclaims industrial chemicals (grease-removing agent and caustic soda) simultaneously, reduces blowdown, and the cleaner production equipment of the closed cycle of water still is blank at home in realizing producing.
Summary of the invention
The utility model is at the deficiency of above-mentioned existence, and degreasing and the water saving of cleaning by degreasing operation subtract dirty consumption reduction device before the application of a kind of rational in infrastructure, good working effect, energy-conserving and environment-protective and provide.
For solving the problems of the technologies described above, the utility model is solved by following technical proposals:
The water saving of degreasing and cleaning by degreasing operation subtracts dirty consumption reduction device before a kind of application, comprise skimming unit, skimming unit is arranged on the sledge-borne type platform, described skimming unit comprises the heating oil eliminator, filters lift pump, adsorption filtration jar, sump oil groove and electrical control cubicles, wherein, the heating oil eliminator is fixedly mounted on the sledge-borne type platform, filters lift pump and links to each other with the heating oil eliminator, and adsorption filtration jar, sump oil groove and electrical control cubicles are fixedly mounted on the sledge-borne type platform from left to right successively.
As preferably, be provided with whipping appts in the described heating oil eliminator.
As preferably, be provided with the grease absorbent filter medium in the described adsorption filtration jar.Grease absorbent filter medium that is provided with the grease absorbent filter medium formed by caking agents such as the pearlstone of 30-60mg and resins in the adsorption filtration jar or forms by carbon fiber and quartz sand or the absorbent filter medium of forming by carbon fiber and gac.The one, can make the emulsified fat in the sewage under high pH value condition, realize the absorption removal; The 2nd, can hold back the suspended substance of removing in the sewage by filtration.
The utility model is in concrete work, and the degreasing cleaning fluid in its pre-treatment degreasing tank needs discharging regularly, contains a large amount of alkali lye and grease in this part degreasing waste water, and PH is more than 14, and oleaginousness is more than 2000mg/L, based on oil in water emulsion.And cleaning by degreasing waste water is divided into twice, contain more alkali lye and grease in the first road rinse water, PH is about 9, oleaginousness contains a spot of alkali lye and grease in the second road cleaning sullage about 100mg/l, PH is about 8, oleaginousness is about 30mg/l, in order to guarantee the workpiece cleaning quality, the water of rinse bath is wanted continuous overflow, therefore produces a large amount of oily(waste)waters.
The utility model is a core technology with breaking milk and removing oil technology under the high pH value condition of waste water and the absorption degreasing technique under the high pH value condition.
After the heating oil eliminator oil removing of degreasing cleaning fluid through having whipping appts, oleaginousness can reach below the 150mg/L, and after the further oil removing of adsorption filtration technology and removing suspended substance, the alkaline water of cleaning is back in the rinse bath then.Finish closed cycle, save fresh water, save the alkali consumption, reclaim greases such as stretching sump oil.
Contain grease and alkali lye that a large amount of workpiece are taken out of after the degreasing in the cleaning sullage.The first road cleaning by degreasing sewage is after collecting, at first regulate pH value by neutralization, pressurization promotes and by the adsorption filtration oil eliminator grease in the sewage is dropped to below the 5mg/l again, suspended substance drops to below the 10mg/l, cleaning water is back to use the second road cleaning sink moisturizing through pressurization, finish the water closed cycle, save fresh water.In order to guarantee the stable of pH value, the PH varitrol is set in sewage recovering system.
The utility model has been owing to adopted above technical scheme, can solve simultaneously from the source application industry pre-treatment degreasing process water saving, reduce blowdown, reduce material consumption and improve the quality of products etc. many-sided technical barrier.Simultaneously, each unit equipment is assembled in and forms an integral body on the steel platform, rectangular structure, and compact construction, rationally distributed, be convenient to operation, install, transport and maintenance; Control is automatically adopted in operation, can realize unattended; Equipment can carry out automatically easily, manual switchover, and is easy to operate.
