Embodiment 1

[0020] (1) Pre-treatment: transfer the hogwash to the hogwash separation tower, add water, heat together to boil, and keep boiling for 4 hours; then use air to boil for 60 minutes to separate the oil from the hogwash, and then centrifuge to separate Solid residue and grease, the grease is transported into the biodiesel production line, and the food residue is kept for later use.

[0021] (2) Hydrolysis treatment: the oil is placed in an alkali refining tank, and water and sodium hydroxide are added for alkali refining. Under stirring, after high-speed emulsification, the oil and soap base are centrifuged and separated by a centrifuge.

[0022] (3) continue to dehydrate the oil obtained in step (2) under the centrifugation state of 5000 revs / min, then input it into a continuous transesterification system and methanol for transesterification, and continuously separate ester and alcohol with a high-speed centrifuge; The obtained ester is washed with 3 times of water and dehydrate...

Embodiment 2

[0028] (1) Pre-treatment: transfer the hogwash to the hogwash separation tower, add water, heat and boil together, and keep boiling for 3 hours; then use air to boil for 50 minutes to separate the oil from the hogwash, and then centrifuge to separate the solids Residue and grease, the grease is transported to the biodiesel production line, and the food residue is retained for future use.

[0029] (2) Hydrolysis treatment: Put the oil in an alkali refining tank, add water and potassium hydroxide to carry out alkali refining at a temperature of 100°C, and then emulsify at a high speed under stirring, then centrifuge and separate oil and soap base in a high-speed centrifuge .

[0030] (3) continue to dehydrate the oil obtained in step (2) under the centrifugal state of 6000 rev / min, then input it into a continuous transesterification system and methanol for transesterification, and use a high-speed centrifuge to continuously separate esters and alcohols; The obtained ester is wa...

Embodiment 3

[0036] (1) Pre-treatment: Concentrate the hogwash into the hogwash separation tower, add water, heat them together until boiling, and keep boiling for 4 hours; then use air to boil for 40 minutes to separate the oil from the hogwash, and then centrifuge for separation Solid residue and grease, the grease is transported into the biodiesel production line, and the food residue is kept for later use.

[0037] (2) Hydrolysis treatment: Put the oil in an alkali refining tank, add water and sodium carbonate to carry out alkali refining at a temperature of 100°C, and then emulsify at a high speed under stirring, then centrifuge and separate oil and soap base in a high-speed centrifuge.

[0038] (3) continue to dehydrate the oil obtained in step (2) under the centrifugal state of 7000 rev / min, then input it into a continuous transesterification system and methanol for transesterification, and continuously separate ester and alcohol with a high-speed centrifuge; The obtained ester is t...

Abstract

The invention discloses a biological diesel manufacturing technology through urban waste water, which comprises the following steps: (1) collecting waste water together; separating solid slag from grease; (2) proceeding alkaline disposal for grease; centrifuging to separate oil and soap base; (3) dehydrating the oil under 5000-8000 r / min; transmitting in the continual ester exchanging system; separating the ester from alcohol; distilling rough product; dehydrating; adding p-toluenesulfonic acid or salt and carbinol; refluxing for 5-7h at 60-70 deg.c; recycling carbinol; washing; distilling the rought product to obtain the product.

Description

technical field [0001] The invention relates to a process for industrially producing biodiesel by utilizing urban sewage. Background technique [0002] At present, with the rapid development of the economy, the shortage of domestic diesel oil market demand has become increasingly apparent, and its supply and demand has become the focus of my country's oil market development. On the one hand, the technical hotspot of refined oil focuses on alternatives, that is, non-petrochemical sources of energy; on the other hand, it lies in the so-called "renewable raw materials", especially animal and vegetable oils. The main components of animal and vegetable oils are fatty acid glycerides, which are biodegradable and environmentally compatible energy sources, and are processed to obtain biodiesel. And also contain a large amount of animal and vegetable oils in the hog oil produced in catering, food industry, but they are not well utilized yet. [0003] The current catering industry, ...
