Abstract
The utility model discloses an efficient esterification reaction vessel. An air ring is coiled on the inner wall of a reaction vessel body of the efficient esterification reaction vessel and is connected with an air pump. The efficient esterification reaction vessel adopts unique structure of the air ring, so as to cause an esterification reaction between methanol under the state of gas phase with grease, thereby enhancing the esterification efficiency. The efficient esterification reaction vessel is especially suitable for the use in production of biodiesel.
Description
Technical field
The utility model relates to technical field of chemical, and specifically, the utility model is a kind of efficient esterifier.
Background technology
At present, biodiesel is that raw material makes with ester exchange reaction with methyl alcohol and grease usually.Conventional esterification is generally carried out in reactor, and efficient is lower, need make improvements.
The utility model content
The purpose of this utility model provides a kind of efficient esterifier.This reactor is adapted to the production of biodiesel especially.
In order to realize above-mentioned utility model purpose, the utility model by the following technical solutions:
A kind of efficient esterifier, coiling has air ring on the inwall of reactor body, and this air ring is connected with air pump.
Described reactor body bottom is provided with drain hole, and the product that is used to react after finishing discharges.
Be provided with agitator in the described reactor body.In case of necessity, can stir reactant.
After a certain amount of methyl alcohol and glyceride stock adding, when treating that temperature is raised to greater than the methyl alcohol boiling point, there are a large amount of methanol steams to produce, at this moment booster air pump makes methanol steam be entered the grease liquid phase by air ring, and esterification takes place.
Because be the reaction of gas-phase methanol and grease, than the liquid phase reactor of routine, gas-phase reaction has increased the surface area of methyl alcohol, thereby has increased reaction surface, sending into of methanol steam can also strengthen combined amount, therefore can improve reaction efficiency.
The utlity model has following advantage:
Efficient esterifier of the present utility model adopts unique air ring structure, make methyl alcohol under gas phase state with grease generation esterification, improved esterification efficient.The utility model is particluarly suitable for using in the production process of biodiesel.

The specific embodiment
Embodiment 1
The structure of efficient esterifier of the present utility model as shown in Figure 1.In Fig. 1, efficient esterifier of the present utility model, coiling has air ring 4 on the inwall of reactor body 7, and this air ring 4 is connected with air pump 6.
Described reactor body 7 bottoms are provided with drain hole 5, are provided with agitator 8 in the described reactor body 7.Also be connected to thermometer 3 and Pressure gauge 2 on the reactor body 7, the temperature and pressure when being used for detection reaction.
During use, after adding methyl alcohol and grease from charging aperture 1 by certain amount, opening steam valve heats up to system, start agitator 8 simultaneously, when treating that temperature is raised to greater than the methyl alcohol boiling point, have a large amount of methanol steams to produce, at this moment booster air pump 6, make methanol steam enter the liquid phase grease, esterification efficiently takes place by air ring 4.
The product of reaction back gained discharges from drain hole 5, after packing, can get product formally.
Because be the reaction of gas-phase methanol and grease, than the liquid phase reactor of routine, gas-phase reaction has increased the surface area of methyl alcohol, thereby has increased reaction surface, sending into of methanol steam can also strengthen combined amount, therefore can improve reaction efficiency.The utility model is particluarly suitable for using in the production process of biodiesel.
More than efficient esterifier provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
