Abstract
The invention provides mobile production equipments and a technological process used for continuously producing biodiesel. According to the invention, biodiesel is continuously produced from animal and plant waste grease and methanol in fixed bed esterification reactors containing solid acid. According to the invention, combined equipments of plural sets of serial fixed beds and separators are adopted. All the equipments are arranged in a mobile room with a size of a freight container, such that the equipments are convenient for transportation and production. The production is continuously carried out with solid acid, normal temperature and normal pressure. Most of the equipments are processed from carbon steel. Therefore, the investment cost is low, the payoff is high. The equipments and the technological process are energy saving and environment friendly.
Description
Technical field
The invention belongs to the biochemical industry technical field of new energies, more specifically relate to a kind of to reclaim the mobile biodiesel production facility and the technical process of propagation waste oil fat and methyl alcohol prepared in reaction biofuel.
Background technology
With the animal-plant oil is raw material, and the fatty acid methyl ester that obtains through methanol esterification can be used as diesel-fuel, the common name biofuel.Biofuel be a kind of can the fast development of regenerated green energy resource in.American-European production biofuel is many to be raw material with alkali refining rapeseed oil and VT 18, adopts the productions of base catalysis and methyl alcohol ester-interchange method.Waste cooking oil and trench main body of oil also are lipid acid, can react synthesizing fatty acid methyl ester with methyl alcohol.But it is many to reclaim grease impurity, and acid number is high, can not use the base-catalyzed transesterification method.Use sulfuric acid, sulfonic acid etc. are as the esterification process of catalyzer, long reaction time, and inconvenient operation, equipment manufacturing cost high duration of service is short to have spent acid to handle again, is not a kind of ideal method.Thereby the solid acid fixed-bed reactor can all even efficiently successive fully contact the catalyzer of reactant in fixed bed to react; What filled in the fixed bed is solid acid catalyst, water resisting property strong, active high, be prone to recycle and reuse, non-environmental-pollution, and the raw oil source is in extensive range, the restriction of acid and alkali value.There is complex manufacturing in existing production of biodiesel, and the equipment manufacturing cost high pollution is serious, technical problems such as high energy consumption, and also waste cooking oil and trench wet goods refiltered oil fat resource relatively disperse, and the transportation back and forth of raw material and product has caused very big cost waste.
Goal of the invention
The present invention is directed to the problems referred to above; Provide a kind of movable type to organize polyphone fixed bed solid acid biodiesel continuous production equipment and technical process, this production unit is simple more, can complete manufacturing and be installed in the prefabricated house of a freight container size and be convenient to carrying; Be convenient to move and can this device be transported to suitable production site energising water flowing and can inject the raw material production biofuel; Avoided the transportation cost back and forth of raw material and product, production cost is reduced, productivity effect significantly improves not only energy-conservation but also environmental protection.
Remarkable advantage of the present invention is: (1) equipment of the present invention is installed in the big or small prefabricated house of a freight container is convenient to carrying; After transporting to production site, connect water power and supporting storage tank, inject raw material and can produce; Avoided the transportation cost back and forth of raw material and product; Production cost is reduced, and productivity effect significantly improves, and the energy 65% is saved in low-temperature atmosphere-pressure production (55-65 degree).
(2) use apparatus and process flow process of the present invention simple, and adopt the DCS system to realize automatic red-tape operati, 2 workmans of easy to operate need are the ability continuous production just, and production unit is cheap, and product need not be washed does not have the sewage discharge environmental protection and energy saving.
(3) good product quality of use device fabrication of the present invention, fatty acid methyl ester can reach about 97%.Each item index reaches the BD-100 standard.
