Problems solved by technology

At present, these waste oils are discharged into the trench together with the waste water, but due to the high freezing point of the oil, especially the meat oil, it is easy to solidify in the trench and form a blockage of the trench
Therefore, waste oil has caused two major problems: one is environmental protection. After the waste water is clogged, it will cause cross flow of waste water, which is easy to stink in summer and seriously affects the environment; the other is waste of resources. Lubricants, preservatives for building materials, release agents, etc.
However, the collection, recovery and purification of waste oil have not been paid attention to at present, and there is no set of standardized technologies

Embodiment Construction

[0018] Fig. 1 has shown a kind of embodiment of the present invention, there is waste oil inlet 2 on the top of recovery separation tank 1, liquid level gauge 3 is arranged in the tank wall middle part, oil outlet valve 4 is housed at the height of liquid level gauge, in The lower part of the tank body is equipped with a waste water outlet valve 5, an agitator 6, a waste water filter screen 7, a low temperature filter screen 8, and a high temperature filter screen 9. The heater installed in the low-temperature filter tank and the high-temperature filter tank is an electric heater or a steam heater, and a waste residue discharge pipe is installed at the bottom of the tank. The sterilizer can be a high-pressure sterilizer or an ultraviolet sterilizer. The waste residue discharged in this process can be used as soil fertilizer after fermentation.

[0019] figure 2 It shows the structure of the well-type oil-water separation device, which is built by using an underground well, wi...

Abstract

The present invention provides a method of extraction and purification of waste oil, relating to recycling of waste resource, waste oil discharged by the present catering trade contains more oil, bringing trench blockage and waste of resource, the resolving steps of the invention include: input the waste liquid in the recycling separation groove, filtering oil in a low temperature and a high temperature after separating oil with water, then vaporizing water; further sterilizing and packing, the product is obtained. The invention not only achieves the recycling of oil resource, protecting environmental sanitation, but also has advantages of simple equipment, convenient operation, easy to extension.

Description

Technical field: [0001] The invention relates to the field of resource recovery and utilization, especially the utilization of waste resources. Background technique: [0002] There is a large amount of waste liquid discharged in the catering industry, which contains a lot of oil, some of which are fried waste oil, some are oil in vegetable soup, and some are oil discharged during washing. At present, these waste oils are discharged into the trench together with the waste water, but because the freezing point of the oil is relatively high, especially the meat oil, it is easy to solidify in the trench and form a blockage of the trench. Therefore, waste oil has caused two major problems: one is environmental protection. After the waste water is clogged, it will cause cross flow of waste water, which is easy to stink in summer and seriously affects the environment; the other is waste of resources. Lubricants, preservatives for building materials, release agents, etc. However, ...
