Abstract
The utility model relates to a device for producing fatty acid by utilizing swill-cooked dirty oil. The device comprises a reaction furnace, wherein a heater is arranged in the reaction furnace, the upper part of the reaction furnace is provided with a sulfuric acid dripper, and the reaction furnace is communicated with a hydrolysis tower; and a vacuum port of the hydrolysis tower is connected with a vacuum device, and the hydrolysis tower is connected with a multi-tower distillation tower through a distillation tower. A process of the device comprises the following steps of: adding vegetable oil leftovers subjected to impurity removal and water into a reaction furnace, stirring, heating, slowly dripping concentrated sulfuric acid, after the reaction is finished, standing still for layering, and separating liquid; (2) washing an oil layer in the step (1) until the pH value is larger than 6.5, after standing still and layering, adding the materials into the hydrolysis tower and heating; when the pressure is 0.65-0.75MPa, carrying out micro pressure relief for exhaust, and maintaining pressure according to an acid material valence; cooling after the reaction is finished, standing still for layering, and then draining recycled water on the lower part to obtain black fatty acid; dewatering and distilling the black fatty acid to obtain refined mixed fatty acid; and then the refined mixed fatty acid is subjected to evaporation and multi-tower rectification to obtain fatty acid and plant asphalt. The device has the characteristics of simple structure, strong practicality and convenience in use.
Description
Technical field
The present invention relates to a kind of device of producing lipid acid, be specifically related to a kind of device that utilizes sewer oil to produce lipid acid.
Background technology
The vegetable oil residue waste material is to refine the tankage that produce in the Vegetable oil lipoprotein processes such as soybean, vegetable seed, cottonseed, this tankage are used as offal treatment always, are not efficiently recovered utilization, also do not have corresponding production equipment, not only caused the wasting of resources, but also serious environment pollution.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of device that utilizes sewer oil to produce lipid acid, have characteristics simple in structure, practical and easy to use.
To achieve these goals, the technical solution used in the present invention is: a kind of device that utilizes sewer oil to produce lipid acid, include Reaktionsofen, and be provided with well heater in the Reaktionsofen, Reaktionsofen top is provided with the sulfuric acid Drop-adding device, and Reaktionsofen is connected with hydrolysis tower; The vacuum port of hydrolysis tower links to each other with vacuum unit, and hydrolysis tower links to each other with the multi-tower distillation tower by distillation tower.
Described hydrolysis tower need not to add any catalyzer in hydrolysis reaction, melt the valency control reaction times according to raw material, and reaction can be finished fully as without catalyst pressurized hydrolysis device.
The beneficial effects of the utility model are:
Because the utility model has adopted without catalyst pressurized hydrolysis device and the continuous vacuum distilling of multitower, mature and reliable can prevent the thermolysis in the lipid acid production process, has improved quality product; Compared with prior art, the utility model facility investment is few, and cost is low, adopts the utility model to produce lipid acid, has significantly reduced production cost, has strengthened enterprise competitiveness.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done step detailed description.
Referring to accompanying drawing 1, a kind of device that utilizes sewer oil to produce lipid acid includes Reaktionsofen 1, is provided with well heater 2 in the Reaktionsofen 1, and Reaktionsofen 1 top is provided with sulfuric acid Drop-adding device 3, and Reaktionsofen 1 is connected with hydrolysis tower 4; The vacuum port of hydrolysis tower 4 links to each other with vacuum unit 5, and hydrolysis tower 4 links to each other with multi-tower distillation tower 7 by distillation tower 6.
Described hydrolysis tower need not to add any catalyzer in hydrolysis reaction, melt the valency control reaction times according to raw material, and reaction can be finished fully as without catalyst pressurized hydrolysis device.
Principle of work of the present utility model is:
During use, 1) the vegetable oil residue waste material after the removal of impurities, water are added Reaktionsofen 1, be heated with stirring to 80～90 ℃, slowly dripping 2.0% the vitriol oil to pH value is 2.0～3.0, and restir 30～40 minutes has reacted rear standing demix, separating liquid; 2) wash oil reservoir in the step 1) with water, to pH value greater than 6.5 o'clock standing demix; 3) with step 2) material of preparation squeezes into hydrolysis tower heating, and pressure is little release exhaust when 0.65～0.75MPa, keeps pressure according to acid material valency, 7.5～8.5 hours periods, bottom Zhong Shui is got rid of in cooling after reaction finishes behind the standing demix, namely obtain black acid; 4) black acid with step 3) obtains refining mixed fatty acid again after the dehydration distillation; 5) the refining mixed fatty acid with step 4) obtains lipid acid and plant asphalt after evaporation, multitower rectifying.
