The utility model is achieved through the following technical solutions, and the utility model comprises quantizer, the first conductivitimeter, the second conductivitimeter, control valve, described quantizer is provided with esterifying liquid entrance, the first esterifying liquid outlet, the second esterifying liquid outlet, acid alcohol outlet and methyl alcohol outlet, the bottom of quantizer is taper, conical lower portion is provided with heating coil, described acid alcohol outlet is positioned at the bottom of quantizer, the first conductivitimeter is positioned in acid alcohol outlet, the second conductivitimeter is positioned in the conical lower portion of quantizer and is positioned on the first conductivitimeter, one end acid alcohol outlet of control valve, the other end connects respectively esterification flow container and acid alcohol tank, the second esterifying liquid outlet is positioned on esterifying liquid entrance, the first esterifying liquid outlet is positioned on the second esterifying liquid outlet, methyl alcohol outlet is positioned at the top of quantizer.
In described quantizer, be provided with sparger, described sparger is connected with esterifying liquid entrance, realizes fully and disperseing.
Described control valve comprises the first ball valve, magnetic valve, visor, the second ball valve, the 3rd ball valve; Described the first ball valve, magnetic valve, visor, the second ball valve are in parallel with the 3rd ball valve again after connecting successively.
Esterifying liquid reaction and an AUTOMATIC ZONING method in production of biodiesel, comprise the following steps:
(1) esterifying liquid after over-churning enters into layering tank from esterifying liquid entrance through sparger, and esterifying liquid is fully disperseed, and in layering tank, acid alcohol is in lower floor, and esterifying liquid is on upper strata;
(2) bottom of heating quantizer, rises methyl alcohol and fully reacts with esterifying liquid, reduces acid number, and the esterifying liquid on upper strata flows out from the first esterifying liquid outlet after sedimentation, realizes continuously and producing;
(3), after charging stops, esterifying liquid starts to flow out from the second esterifying liquid outlet;
(4) acid alcohol flows out from the first conductivitimeter, according to the difference of esterifying liquid and acid alcohol specific conductivity, makes the liquid level of acid alcohol in whole quantizer can not increase.
The utility model has the following advantages compared to existing technology: the utility model has improved the speed of esterifying liquid layering greatly, and can make the efficiency of acidification reaction still improve, guaranteed layered effect, and played the effect of secondary esterification, and made to produce and become possibility continuously.
