Problems solved by technology

However, there are indeed some unscrupulous traders who are driven by profit and do not care about the safety of the people to privately produce and process "waste oil" and sell it as edible oil to some small restaurants at a low price, which has the defect of causing great harm to people's body and mind.

Embodiment 1

[0021] Reference figure 1 As shown, a system device for refining waste-ditch oil includes a recovery tank, a sedimentation metering tank, a hydrolysis tower, a black fatty acid dehydration tank, a distillation tower system, a fatty acid tank, a soap powder batching tank, an aging tank, a high-pressure pump, Powder spraying tower, heating system, mixing tank, finished product warehouse, packaging finished product warehouse; the waste meal oil and water are pumped into the recycling pool 2 through a water pump or valve 1, and the waste meal oil and water in the recycling pool 2 passes through the precipitated supernatant The sedimentation metering tank 3 sends the supernatant liquid to the hydrolysis tower 4, the hydrolyzed liquid is sent to the black fatty acid dehydration tank 5, the dehydrated black fatty acid is sent to the distillation tower system 7, and the distilled steam passes through the vacuum system and The condenser becomes fatty acid and is sent to the temporary sto...

Embodiment 2

[0023] An application method for extracting waste oil and waste oil from the system device described in the following steps:

[0024] 1). Pour the recovered waste oil and water into the recovery tank and pass it into steam for cooking. When the material is turned over, add 1.5 to 2 parts of sulfuric acid according to the mass ratio of the waste oil and water, and let it continue to cook for 3 to 5 hours, then stop cooking Settling for 2 to 3 hours;

[0025] 2) Take the supernatant liquid and pump it into the sedimentation metering tank 3 equipped with a measuring scale, continue to settle for 5 to 8 hours to drain the sedimentation and residue, and recycle the discharged sedimentation and residue;

[0026] 3). Analyze the acid value of the settled neutral oil, determine the hydrolysis time according to the acid value, and then pour the settled neutral oil into the hydrolysis tower 4 at the ratio of 3 parts to 2 parts according to the oil and water. 4 Heat with steam and increase the...

Embodiment 3

[0033] An application method for extracting waste oil and waste oil from the system device described in the following steps:

[0034] 1). Pour the recovered waste oil and water into the recovery tank and pass it into steam for cooking. When the material is overturned, add 2 parts of sulfuric acid according to the mass ratio of the waste oil and water, let it continue to cook for 5 hours, and then stop cooking for 3 hours;

[0035] 2). Take the supernatant liquid and pump it into the sedimentation metering tank 3 equipped with a measuring scale, continue the sedimentation for 7 hours to drain the sedimentation and residue, and recycle the discharged sedimentation and residue;

[0036] 3). Analyze the acid value of the settled neutral oil, determine the hydrolysis time according to the acid value, and then pour the settled neutral oil into the hydrolysis tower 4 at the ratio of 3 parts to 2 parts according to the oil and water. 4 Heat with steam and increase the pressure for hydrolysis...

Abstract

The invention discloses a system device for extracting waste-swill-cooked dirty oil and an extraction method. The system device comprises a recycle pool, a sedimentation measuring tank, a hydrolyzer, a drain sump, a distillation tower system, a fatty acid material tank, a soap powder compounding tank, an aging tank, a high pressure pump, a spray tower, a heating and vacuum system, a mixed cylinder and a finished product warehouse; and the method comprises digestion, sedimentation, hydrolyzation, oil-water separation, dehydration, distillation, condensation, soap power compounding, aging, airflow drying, mixing and packaging. Therefore, the environment is protected and improved, wastes of high energy consumption, high pollution and resources industries are utilized efficiently and comprehensively, the pollutant emission is reduced, swill-cooked dirty oil is prevented from flowing back onto dinner tables to harm human health, harmful wastes harming environment and human life safety are turned into valuable things; and stearin pitch is used as raw materials of sand consolidation agent and rubber accelerator, the soap powder is applied as raw materials of washing powder or soap, and the system device and the extraction method are widely used in recycle industry of swill-cooked dirty oil.

Description

technical field [0001] The invention relates to oleochemical equipment and a method for recycling and refining waste, in particular to a system device for refining waste oil and an application method for refining waste oil and waste oil. Background technique [0002] The catering industry on the market needs to discharge a large amount of waste every day, i.e. leftovers and leftovers. These wastes are commonly called swill, and waste oil is the garbage that flows quietly in the urban sewer. Some scouts processed it and turned it into "edible oil" on the table. They take a large amount of dark, turbid, reddish paste from there every day, and after just one night of filtering, heating, precipitation, and separation, they can turn these foul-smelling garbage into clear "edible oil" and finally pass through Sell ​​at low prices and return to people's dining tables. This three-free product called "waste oil" is still triglycerides as its main component, but it has many more pat...
