Embodiment 1

[0028] (1) Add 500 kg of waste oil into a 1500 liter enamel reaction tank, then add 400 kg of clear water, heat up to 60°C, stir for 1 hour, dissolve and mix;

[0029] (2) add 40 kilograms of NaCl in above-mentioned retort, stir and simultaneously insulate 30 minutes, leave standstill then, oil layer, water layer appear;

[0030] (3) Separating the oil layer and filtering it with a 30-purpose filter screen to obtain the filtrate;

[0031] (4) Weigh 300 kg of filtrate, put it into a 1000-liter reaction tank, add 30 kg of activated carbon and activated clay mixture in a ratio of 1:8, heat up to 140 ° C, stir for 1.5 hours, filter with a 60-mesh filter screen, and obtain the filtrate ;

[0032] (5) take step (4) and make 400 kilograms of filtrates, add 180 kilograms of clear water, volume concentration is 50 kilograms of industrial grade sulfuric acid of 76%, volume concentration is 3 kilograms of alkylbenzenesulfonic acids of 1%, stir and be warming up to 110°C, react for 12 h...

Embodiment 2

[0039] (1) Add 500 kg of swill oil into a 1500 liter enamel reaction tank, then add 350 kg of clear water, heat up to 75°C, stir for 1 hour, dissolve and mix;

[0040] (2) add 35 kilograms of NaCl in above-mentioned reaction tank, stir and simultaneously insulate for 30 minutes, leave standstill then, oil layer, water layer occur;

[0041] (3) Separating the oil layer and filtering it with a 30-purpose filter screen to obtain the filtrate;

[0042] (4) Weigh 350 kg of filtrate, put it into a 1000-liter reaction tank, add 40 kg of activated carbon and activated clay mixture in a ratio of 1:7, heat up to 150 ° C, stir for 2 hours, filter with a 70-mesh filter screen, and obtain the filtrate ;

[0043] (5) Take by weighing 300 kilograms of filtrate obtained in step (4), add 200 kilograms of clear water, 60 kilograms of sulfuric acid with a volume concentration of 50%, and 4 kilograms of alkylbenzenesulfonic acids with a volume concentration of 1%, stir and be heated to 120° C. ...

Embodiment 3

[0050] Weigh raw materials according to the following weight ratio:

[0051] 100 parts of waste oil, 12 parts of 50% dilute sulfuric acid, 20 parts of caustic soda, 4 parts of a mixture of activated carbon and activated clay with a weight ratio of 1:6, 0.8 parts of alkylbenzenesulfonic acid, 8 parts of sodium chloride, and 16 parts of high-efficiency additives , 12 parts of a mixture of sodium sulfate, sodium carbonate and sodium silicate.

Abstract

The invention discloses a kind of use ditch oil or slops incompatible highly effective washes clothes with the soap powder method, including the ditch oil or slops the incompatible pretreatment, the ditch oil or slops the incompatible acidification, the ditch oil or slops the incompatible saponification, the saponified fluid synergize, bestows on the shape, makes grain, is dry and so on the step. The invention method, both reduced the ditch oil either slops incompatibly and has stopped up the derelict land ditch oil to the environment pollution from the source or slops incompatible two edible, has guaranteed people's health, moreover also provides the sufficient raw material supply for the fat chemistry, simultaneously this method also has the soap powder decontamination strength which the production cost low, makes to be strong, not injurying also the non- pollution characteristic, has the better application promotion value.

Description

technical field [0001] The invention relates to a method for producing soap powder, in particular to a method for producing high-efficiency soap powder for laundry by utilizing waste oil or swill oil. Background technique [0002] With the improvement of living standards, the consumption of various foods is gradually increasing, and the remaining meals of people in daily life, the fats and oils discarded by restaurants and food processing enterprises, and the fats and oils retained by waste water after washing tableware are also increasing rapidly. , and most of these oils, which are usually regarded as garbage, enter the sewer, forming what is often referred to as waste oil. Because waste oil biodegradability is very slow, it causes surface and geological water pollution, which brings serious harm to the ecological environment. [0003] The problem of how to deal with waste oil or swill oil has always been a subject of concern. And now there are people who are motivated b...
