Description
Technical field
The utility model relates to the device of esterification, and particularly a kind of sewer oil esterification device belongs to the oil and fat chemical equipment technical field.
Background technology
Biofuel is a fatty acid methyl ester, is typical " green energy resource ", is fine petrifaction diesel substitute.At present, biofuel mainly prepares by greasy esterification, discovers, nearly all grease can be as biodiesel raw material, but is that the biofuel of raw material production is on the high side with the Vegetable oil lipoprotein, has limited popularization.Adopting cheap raw material, is raw material as the ageing oil of the tankage in the edible oil course of processing, waste cooking oil, oil expression waste residue, grain reserves, useless lard and inedible oil etc., and raw materials cost is reduced greatly.But the oily most acid number of these cheapnesss is all higher, should not directly adopt the base-catalyzed transesterification legal system to be equipped with biofuel.At present, the equipment aspect the esterification of acid catalysis sewer oil is complicated, the production cost height, and production efficiency is low.Therefore designing a kind of sewer oil esterification device simple, that cost is low and efficient is high has great importance.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of sewer oil esterification device is provided, and its equipment is simple, and production cost is low, can realize carrying out fast continuously of sewer oil esterification reaction of organic acid, improves feedstock conversion efficient.
The utility model is finished by the following technical programs: the esterification reaction of organic acid still bottom of band well heater is by the methanol gas producer of pipe connection band well heater, the outlet of esterification reaction of organic acid still is by pipe connection product separation tower, and the catalyst outlet of product separation tower bottom is with the inlet of pipe connection to the esterification reaction of organic acid still.
All be provided with safety valve on the top cover of esterification reaction of organic acid still and methanol gas producer, esterification reaction of organic acid still top is provided with the methyl alcohol outlet and by the pipe connection heat exchanger entrance, heat exchanger exit feeds methanol gas producer bottom after connecting surge tank again.
The sewer oil and the catalyst inlet of esterification reaction of organic acid still are arranged on the top, and the pipeline of esterification reaction of organic acid still outlet is provided with transferpump; The methanol feed mouth of methanol gas producer is arranged on top.
Its working process is:
At first, in the esterification reaction of organic acid still, add sewer oil and acid catalyst, be warming up to preset temperature by the well heater that carries on the still; Then, add methyl alcohol in the methanol gas producer, its well heater work produces methanol gas, feeds the bottom of esterification reaction of organic acid still through pipeline, with sewer oil generation esterification reaction of organic acid in the still, react remaining methyl alcohol and take the moisture that produces out of the esterification reaction of organic acid still simultaneously; The aqueous methanol steam by the interchanger condensation after surge tank return in the methanol gas producer 2; Esterification reaction of organic acid changes material over to the product separation tower and separates after finishing, and obtains the product fatty acid methyl ester, and the catalyzer of separating returns the recycling of esterification reaction of organic acid still at the bottom of tower.
Positively effect of the present utility model: this apparatus structure is simple, and production cost is low, adopts the mode by taking away the water in products branch to realize carrying out fast continuously of sewer oil esterification reaction of organic acid, has improved feedstock conversion efficient.
