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.
Installation:
According to the foundation drawing of this type equipment to install it, adjust
the level, specially the longitudinal level must be ensured 1‰within requirement,
then fixed foot margin , connect all pipeline and valve according to the
installation drawing, installed all components such as sight glass as request,
wait to debug.
Technique data:
According to sewage ‘s variety and Emulsification degree , The oil removal rate of
the exit sewage emulsified fuel after multistage flotation can reach
70%-90%( if contain Soluble oil,emulsified oil can be dispose by dosing ) ,the
removal of suspended can reach 50%-80%; the removal of COD can reach
50%,this series equipment’s dispose capacity is 10-800 CBM, its main
performance index can achieved the international similar product level in the
1990s, leading position in china.
Dispose medium temperature : 0-80 ℃
Jet pump power: 380V,50HZ or customized according to client
