Abstract
The utility model belongs to the technical field of equipment for producing biodiesel, and particularly relates to a methanol recycling device for a biodiesel production process. The device comprises a first level condenser, a cooling buffer tank, and a second level condenser, wherein the cooling buffer tank is communicated with an outlet of the first level condenser, a steam outlet is arranged at the top of the cooling buffer tank, and a drain port is arranged at the bottom; an outlet of the second level condenser communicated with the steam outlet is arranged at the top of the second level condenser, and an outlet of the second level condenser is arranged at the bottom. During use, the first level condenser primarily condenses methanol steam, almost vapor is condensed and separated out and collected in a tank after entering into the cooling buffer tank, methanol steam which is not condensed enters into the second level condenser to be condensed to liquid methanol with low water content and is returned to a workshop section of producing the biodiesel through the outlet of the second level condenser, thus, the problem that the methanol steam produced by producing biodiesel or produced in other chemical production flows related to methyl esterification cannot be directly recycled is solved, thereby effectively reducing the energy consumption and lowering the production cost.
Description
Technical field
The utility model belongs to production biofuel equipment technical field, relates in particular to a kind of Methanol Recovery re-use device for production of biodiesel process.
Background technology
Methyl alcohol is the raw material that must use in production biofuel or other Chemical Manufacture flow processs relevant with esterification; these Production Flow Charts all need constantly to add a large amount of methyl alcohol; therefore in Production Flow Chart, often can produce many methanol steams, its methanol content is usually up to more than 90%.The methanol steam of directly draining, can pollute environment on the one hand, can cause the wasting of resources on the other hand.
Because can hindering the forward of esterification reaction of organic acid, the existence of water carries out, therefore require the methyl alcohol water content added in Production Flow Chart very low, and the water content of the methanol steam that these generate is on stream all higher, so these methyl alcohol all can not directly be recycled, need to, by methanol steam rectifying, obtain highly purified methyl alcohol recycling.
At present, common way is first methanol steam to be made it to become liquid through condensation, again these liquid are delivered to methanol rectifying tower, reheat, finally could the very high methyl alcohol of output purity through gas-liquid conversion for several times back and forth, this process to consume a large amount of energy and also equipment cost high, increased production cost.
Granted publication number is the utility model patent of CN 202022865 U, a kind of device of recovering excessive methyl alcohol in biodiesel production by low energy consumption is disclosed, its cardinal principle is to replace traditional rectifying tower with the device that the condenser of a set of infiltration vaporization membrane module and connection thereof, receiving tank, surge tank and vacuum pump form, thereby has reduced the cost of energy consumption and production process.Yet the raw material in China's production biofuel is taken from sewer oil more, its complicated component is very high to the foreign matter content of the toxic effect of infiltrating and vaporizing membrane, so this device is also inapplicable concerning the enterprise of most of production biofuel of China.
