Description
Technical Field
The utility model relates to a biodiesel production technical field, concretely relates to biodiesel waste water circulation processing apparatus.
Background
The biodiesel is used for refining automatic vegetable oil, and is commonly used for tractors, trucks, ships and the like. The renewable diesel fuel is prepared from oil crops such as soybean, rape, cotton, palm and the like, aquatic plant oil and fat such as wild oil plants, engineering microalgae and the like, animal oil and fat, food and beverage waste oil and the like serving as raw materials through an ester exchange or thermochemical process and can replace petroleum diesel. Biodiesel has excellent environmental properties: the sulfur content of the biodiesel is lower than that of the petrochemical diesel; has good safety performance: the flash point of the biodiesel is higher than that of the petrochemical diesel; has excellent combustion performance: the cetane number of biodiesel is higher than that of diesel oil. Therefore, the biodiesel is a real green diesel.
The raw material cost is high under the national 'four-in' policies of 'not meeting the land with grains', 'not meeting the grains with people', 'not meeting the oil with people' and 'not polluting the environment' when the biodiesel is prepared by adopting oil crops, so that the cost reduction of the biodiesel prepared by the illegal cooking oil is the key for the practicability of the biodiesel. In the prior art, the illegal cooking oil and methanol are esterified to generate fatty acid methyl ester in the presence of a solid strong acid catalyst, the esterification reaction needs to be cooled by a large amount of circulating water, green algae can be generated on the inner walls of a pipeline and a water tower in the using process of the circulating water, the running of a circulating water system can be seriously influenced by the excessive accumulation of the green algae, at present, the chemical cleaning agent is added into the circulating water system to eliminate the green algae, the chemical cleaning agent is not environment-friendly and has influence on the water quality, in addition, the waste liquid of the esterification reaction catalyst contains a large amount of water, the waste liquid does not have a recovery treatment device at present, but is directly discarded, so the water resource cannot.
