jet flow air flotation purifier for oil pipelien washing water

high efficient jet flow air flotation purification machine (degreaser)

Introduction

The main function of YM series high efficient jet flow air flotation purification machine (degreaser) is remove oil and suspended matter in the sewage, which is improved to be series air floation purification machine by our company using foreign technique. Its predecessor equipment is invented by American WEMCO on 1980 ,this equipment is rectangle tank, the entrance and exit of water is

setup in both ends of tank, the top of tank install 4pcs motors ,this motors will drive respectively impeller in trough form into 4 grade aeration, both sides of flotation tank set scraper used in scrape oil, then the motor drive the scraper to achieve the purpose of oil-water separation by scraping out the flotation oil .Our company import this technique in 1993,after digestive absorption,

begin to produce the second generation Floating purification machine ,which solved the original equipment ‘ s shortcoming of Aeration bubble large particle size ,bubble scatter uneven,low removal rate of oil . our company made a Comprehensive Analysis of operation condition to each spot in 2001, then made technical transformation once again and produced the third generation jet flow

air flotation machine, and got good valuation from client.

The jet flow air flotation purification machine( degreaser) has widely used in

each big coking plant and Oil Refinery in nationwide,it has obvious remove effect

in dealing with Surplus ammonia, Phenol cyanide wastewater,tar in Washing-rich

liquid,oil in discharge water of offsite, mainly solved the puzzle question of

ammonia distillation tower and heat exchanger blocking constantly which will

affect normal production.

The removal oil effect of jet flow air flotation purification machine ( degreaser)is

more obvious in Petrochemical Industry , such as the first factory of DaQing

petroleum and other factory, Liaohe Oilfield, Dagang oilfield, Qilu

Petrochemical,Fushun petroleum etc.

The treated wastewater can meet up to the emission standard of national

regulation(special wastewater can dispose by dosing chemicals). This equipment

especially win the bidding by defeating American Mcwong Air flotation machine

in Beijing Yanshan Petrochemical sewage project .

Dozens of coking plants and iron and steel company,oil-field all adopt our

company produced jet flow air flotation purification machine ( degreaser) at

present, in application of flotation technique,our company’s bid rate above 90%

in Engineering bid.

Scope of application :

YM series jet flow air flotation purification machine ( degreaser) is an Efficient

energy-saving patented product in purifying sewage which new developed by our

company, various indicators of this equipment has reached to international

advanced level, this machine apply to treating sewage in oil-field ,refinery ,

petrochemical industry,metallurgy,steel rolling,coking,leather,machining,

generate electricity,municipal engineering,,textile,Dyeing and Finishing and

Light Industry etc, which can effectively remove oil,suspended matter ,organic

matter and heavy metal etc.

Operating principle :

YM series jet flow air flotation purification machine ( degreaser) absorb air into

water system by circulating water pump(jet pump) in jet flow manner, forming air

water admixture , the air water mixed liquid pass dissloved air vessel respectively

enter into 4 aeration regulator, then return equipment by release head, the

bubble size processed by release head will be small ,make them adhere to

floccule surface, thus separate the pollutant in water. The pollutant in different

position of equipment will focus discharge into the under tank or mechanize

clarifying tank after collected. The water after purify can be reuse ,air flotation

purification machine has advanced jet flow dissolved air system, which realized

multilevel tandem type flotation, improve the removal rate of oil or suspended

matter.

Application characteristic:

No power slag draining, the main parts of such equipment is round tank

shape ,so its sealing property is fine when operation, the flotation air can recycle,

the medium odour can’t leak easily, no secondary pollution. The slag draining

way is overflow, without power, no operation parts, make waste residue drag-in

to dump tank fully relying on water flow then outflow equipment external. So its

failure rate is 0, no need maintenance, reduce operation cost.

The equipment has big sewage treatment yield, short water retention time, only

15-20 minutes.

Wide Applicability range, good operation environment,, the water pump

can install indoor, main parts of equipment installed outdoor, no noise.

Which can add different floating agent (organic, inorganic) aiming at different

sewage, also can adopt 2-8 grades different flotation manner, the size and

quantity of micro bubble generated can be adjusted, all kinds of sewage

purification can get ideal effect. Low energy consumption, easy to manage and

operate, can save electricity 40% than other flotation machine, low operating

expense, only need 1 water pump (jet flow pump) can ensure the equipment

stable operation, can start operation or stop at any time.

As the aeration manner Is second dissolved air ,so the flotation bubble size

is small and more bubble.,the particle size is between 10-60 micron, and the

20-30 micron particle size will be above 70%,specially suit to flotation, its

flotation effect is good, high remove rate than other air flotation machine, no

second pollution,the released gas can be recycle, only need replenish little gas.

Small occupying area, convenient install, small one-time investment .

Low sewage treatment expense, the main parts is made of composite steel

plate (Lined with stainless steel plate) according to user’s requirement, improve the service life .

Fully automatic operation, no need personnel operate, property stable, safety and reliable.
