Description

Adopt new catalyst to handle the sewer oil technology

Affiliated technical field

The present invention relates to adopt a kind of new catalyst, adopt the high-temperature high-pressure craft condition, handle idle or waste animal and vegetable oil, especially sewer oil.

Background technology

Sewer oil is that the mixture that flows into the composition complexity that various greases in the water drain, food debris (comprise rice, noodles, respectively plant vegetables leaf, capsicum, Chinese prickly ash etc.) and wooden chopsticks etc. form with water is scrubbed in the tableware process in family or restaurant, hotel etc.These materials form a kind of brown, thickness, have malodorous congee shape body through biological fermentation.If through particular processing, IT for oil trap.At present, some illegal retailers but simply are processed into edible oil with oil trap rubbish, are passed to have threatened directly on the market that people's is healthy again.For preventing this from occurring, various countries have taked various measure.For example:

The edible waste oil of the U.S. reclaims mainly through two steps.The first step all is equipped with " kitchen waste pulverizer " with the scullery basin below of family kitchen at the restaurant.People need screen for the first time, earlier with those meat slags, dish leaf and so on stodge not too, directly smash the back by this machine and discharge from water drain; In second step, the food that those oil contents are high can not be put into pulverizer, but need collect specially, pours in the special-purpose refuse container, and the waste oil in these barrels will be unified to be reclaimed by the edible waste oil recovery company of the U.S..These companies must obtain the business licence that health and environmental administration issue, and have transportation, recovery and the processing units of specialty.Company can regularly reclaim waste oil from restaurant and Residential areas.

There were three steps in Britain for the treating method of catering industry waste oil at present: waste oil is poured in the free container of providing of government; Company by government's approval is responsible for collection again; These oil are processed into products such as available biofuel the most at last.

In the kitchen in New Zealand restaurant, food garbage treater and fat separator device are installed all.This device need not manually carry out the oleaginousness screening to food waste and leftovers, unified being poured in the machine, and those residues can be entered water drain after pulverizing and the harmless treatment; And those have and will be separated after greasy waste water will flow into fat separator device automatically again, and waste oil and fat are stored in separately in the another one container, are responsible for collection by specified company of government.

In Germany, the restaurant must be signed " swill recovery contract " with government.Every day, the swill in the dining room enters the swill treatment facility by pipeline.Through 6 road programs such as precipitation, separation, sewer oil is separated.The unified recovery of company that the oil of separating is given special approval to by government.The waste oil of retrieving, except making biofuel, many enterprises also therefrom extract special composition, are used to produce chemical, organic fertilizer etc.Germany's sewer oil recovery utilization rate has reached 100%.

Japanese government's high price reclaims waste oil from food and beverage enterprise, adds Viscotrol C in the waste oil of retrieving at once, has so not only made things convenient for when purifying in the future and has used, and has prevented fundamentally that also sewer oil from flowing to dining table again.Specialized company will be processed into the sewer oil that reclaims can supply dumper incendiary biofuel.

Summary of the invention

Again flow back to dining table for fear of sewer oil, optimal scheme is that the energy is extracted again, recycle.The invention provides a kind of novel treatment technology, adopt new catalyst, from the depleted sewer oil, successfully extract biofuel.No. 0 fossil diesel fuel of this biofuel sulfur-bearing numeric ratio is low, and 16 alkane values are higher than fossil diesel fuel, and aromatic free and heavy metal contain oxygen value 11% and can guarantee sufficient combustion, does not almost pollute, and belongs to the clean fuel liquid product.

This kind new catalyst main component is a methyl cyclopentyl-dialkyl-tricarbon manganium, mainly act as the colloid that destroys in the mixture, and solid, liquid and colloid are separated.

The technical solution adopted for the present invention to solve the technical problems is: the sewer oil after will filtering adds catalyzer, enters reaction unit through feeding device, according to the difference of each component vapour point under differing temps and the pressure condition, isolates different products.High temperature, high pressure and the gas that has a charcoal are through the carbon removal device in the filtration unit, with charcoal row down, and through desulfuration carbon removal removal of impurities, enter orderly the reacting of stable-pressure device, final assurance oil gas, oily water separation, the continuous output biofuel of rectifier unit, gas and moisture content waste liquid, waste water is finished the Chemicals of production high added value again by reaction unit.

The invention has the beneficial effects as follows, the sewer oil that is detrimental to health can be carried out efficient recovery, reach the resource circulation utilization, produce effective biofuel, sewer oil is turned waste into wealth.
