Further, can also comprise storage compartment and cyclic part, described storage compartment adopts accumulator tank, and described cyclic part adopts circulating pump and circulation pipe; The tube side of described pipe heat exchanger is connected with the entrance of described accumulator tank, the outlet of described accumulator tank is connected with one end of the circulation pipe of cyclic part, the other end of described circulation pipe connects the charging aperture of described mixing portion, is provided with circulating pump in the middle of described circulation pipe.
Further, the circulation pipe between circulating pump and recycle stock charging aperture is provided with discharge valve.
Further, the charging aperture be connected with described circulation pipe is arranged on the top of described mixing portion.
Concrete technological process is: first, by water through transport pump to water inlet, then reactive moieties is spurted into through the injector head be arranged on water inlet, then raw material is delivered to charging aperture through dehvery pump, mixing portion is injected into through the injector head be arranged on charging aperture, the liquid distributor of raw material under gravity through being arranged on reactive moieties entrance flows into reactive moieties, and at reactive moieties and water generation hydrolysis, then accumulator tank is entered, after under the effect of circulating pump, the product in accumulator tank is delivered to the charging aperture be arranged on bottom mixing portion, recycle stock spurts into mixing portion through the injector head be arranged on charging aperture, recycle stock fully mixes at mixing portion with raw material, then the liquid distributor under gravity through being arranged on reactive moieties entrance flows into reactive moieties, and at reactive moieties and water generation hydrolysis, then accumulator tank is entered, according to described regular cycles.Circulation pipe between circulating pump and recycle stock charging aperture is provided with discharge valve, can judges whether to reach quantity-produced requirement by the concentration detecting product in discharge valve place recycle stock, thus judge whether to open discharge valve.
Hydrolysis controls in relatively little scope by the utility model, hydrolysis in less space makes the control of condition relatively easy, the injector head being arranged on charging aperture and water inlet makes raw material, recycle stock and water fully to mix, the exchange heat that hydrolysis produces can promptly be walked by the pipe heat exchanger of heat exchanging part, thus can in more among a small circle controlled hydrolysis reaction temperature effectively, hydrolysis is steadily carried out, ensures the controllability of hydrolysis condition and higher security.
