At present, the crystalliser volume generally used of monosodium glutamate industry is 12m
3, 15m
3More, maximum also is no more than 50m
3
3, automaticity is low, the technology instability, and the ability of resisting the raw material quality fluctuation is also poor, thereby impurity content is higher in the monosodium glutamate finished product, the production cost height.
(3) utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of continuous crystalizer that steam is low, equipment capacity is high and automaticity is high that consumes is provided.
The purpose of this utility model is achieved in that a kind of continuous crystalizer, from top to bottom successively by upper cover, go up cylinder, upper cone, middle cylinder, lower cone and bottom (head) is end to end forms, described going up in the cylinder is horizontally arranged with a shower, be connected with a magma circulation port and inoculation mouthful on below the described shower on the cylinder barrel, in described upper cone and middle cylinder, be respectively arranged with an inner cone and an inner barrel, inner cone is inverted cone shape and is connected in the inner barrel top, is provided with a guide shell in described inner cone, inner barrel and lower cone; The cylinder barrel is provided with a circulation discharging opening in described, described lower cone barrel is provided with one and loops back head piece and magma outlet, be provided with an internal circulation pump in the bottom of described crystallizer, the import of this internal circulation pump and the intracavity inter-connection of crystallizer, the outlet of this internal circulation pump is arranged in the described guide shell, be provided with trap at described upper cover top, this trap has umbrella-shaped baffle, is provided with indirect steam outlet at the trap side.
The beneficial effects of the utility model are:
1, crystallizer equipment enlarging, production capacity increases.
The volume of crystallizer has been broken through the conventional size of gap single-action condensing crystallizing device, can reach 80m
3More than.And general gap crystallizer has only 20m
3About, amplify doubly a lot of.Not only equipment capacity is greatly improved, but also has saved the table of equipment number, has reduced investment cost.It is reported, build identical production-scale monosodium glutamate device.The investment of continuous crystalizer technology will be saved more than 30%.
2, continuous crystalizer operation serialization, production cost descends.
Continuous crystalizer technology has been improved the recurrent state of crystallization solution, has reduced degree of supersaturation, and is very favourable to the growth of the formation of nucleus and crystal.Thereby crystallization temperature has descended, and percent crystallization in massecuite is enhanced, and magma can be from extraction continuously in the crystallizer.Realized the operation serialization, required operating personnel reduce significantly, and labor productivity is enhanced.
3, continuous crystalizer can be realized automation control, and quality further improves.Show that mainly impurity is few, the appearance luster light, long crystal formation crystallization is evenly neat.
The gap crystallizer is in order to obtain higher percent crystallization in massecuite, have to rely on the means that improve degree of supersaturation to realize, but degree of supersaturation is high more, the viscosity of magma also sharply raises, viscosity raises and is unfavorable for crystallization, must improve crystallization temperature again as reducing viscosity, chromogenesis and pyroglutamic acid influence product quality and crystalline rate so inevitably.Continuous crystalizer has been implemented the key process parameter feedback controls, and inside and outside internal circulating load and advance jar steam and rationally set has been optimized technology greatly, and impurity obviously reduces in the product, and quality is greatly improved.
Comprehensively above-mentioned, continuous crystalizer of the present utility model has production capacity height, characteristic of low energy consumption.
