Abstract
The utility model discloses a xylose production vertical continuous crystallizer which belongs to a xylose production device and comprises a case and a flat cover, wherein the case is a vertical barrel-shaped container; the top part of the case is provided with the flat cover; the flat cover is provided with a hydraulic lifting device; the top part in the case is provided with a drapery device; 2-5 groups of cooling coil pipes are arranged below the drapery device; the cooling coil pipes are respectively communicated with a cooling medium distributing pipe by the lifting pipe; the lower part in the case is provided with a taper end enclosure; a scraper device is arranged on the taper end enclosure below the cooling coil pipe; and a seed crystal circulation pipeline is arranged outside the case. Compared with the prior art, the xylose production vertical continuous crystallizer has the following advantages: (1) the problem that xylose crystal production can not be continuous is solved, continuous turnout of materials is realized, and continuous run of the production is ensured; (2) a plurality of the coil pipes lower the temperature in gradient mode, the temperature reduction of the materials is uniform and controllable, and the crystallization effect is good; (3) and the labour intensity of workers is reduced.
Description
Technical field
The utility model relates to a kind of xylose production device, specifically xylose production vertical continuous crystallizer.
Background technology
The technical process of xylose production is: raw material, and------------ion-exchange---evaporation concentration---crystallization---wood sugar finished product decolours in hydrolysis in pre-treatment.Crystallization Procedure is that oversaturated xylose solution is slowly lowered the temperature, and reduces the saturation solubility of wood sugar, and adds the crystal assisting crystallisation of some amount, and the wood sugar crystal is separated out.Its crystallization processes all utilizes horizontal crystallizer at present, adopt the intermittent type crystallization process, promptly at first horizontal crystallizer is filled with material,, when dropping to certain temperature, add an amount of crystal assisting crystallisation then according to the temperature lowering curve gradient cooling, stir simultaneously, make whole jar of temperature of charge identical as far as possible, finish up to crystallisation process, after crystallization is finished, material in the crystallizer tank is all delivered to separation circuit, charging again then.This production technique exists every crystallizer tank crystallizing cycle of various disadvantages (1) all to comprise independent charging, add crystal seed, growing the grain etc., has caused crystallizing cycle long, and production efficiency is low; (2) the crystallizer tank capacity is little, if increase output, then needs to increase the quantity of crystallizer tank, and frequent operation expends great amount of manpower; (3) crystallizer tank adopts the chuck cooling, and material is heated inhomogeneous, overall cooling of influence and crystallization effect; (4) the crystallizer tank stirring wing makes the crystal grain fragmentation easily, makes finished product crystal grain inhomogeneous.
Summary of the invention
Technical assignment of the present utility model is at above weak point, and a kind of production efficiency height, xylose production vertical continuous crystallizer that crystallization effect is good are provided.
The technical scheme that its technical problem that solves the utility model adopts is: this crystallizer comprises housing and flat cover, housing is the vertical barrel type container, the top of housing is provided with flat cover, flat cover is provided with hydraulic lifting apparatus, be provided with distribution device at the intravital top of shell, the below of distribution device is provided with 2-5 group spiral coil cooling tube, spiral coil cooling tube is communicated with the heat-eliminating medium distribution piping by riser tube respectively, the intravital bottom of shell is equipped with conical head, on the conical head of the below of spiral coil cooling tube scraper is installed, housing is outside equipped with the crystal seed circulation line.
Described hydraulic lifting apparatus comprises the frame that is rigidly connected, hydro-cylinder and hydraulic power unit, and riser tube is installed on the frame that is rigidly connected, hydro-cylinder by pipeline be arranged on the lateral hydraulic power unit of housing and be communicated with.
During use, need the crystalline material to enter housing, material and crystalline seed are evenly distributed to the equipment cross section by distribution device by feed-pipe.Heat-eliminating medium divides the multichannel countercurrent flow to feed spiral coil cooling tube by distribution piping, and the multilayer spiral coil cooling tube is equivalent to a plurality of single crystallizers that connect successively in order, and equipment is divided into the different crystallizer of a plurality of cooling conditionss.Each crystallizing range that material successively decreases through thermograde from top to bottom, crystallization gradually, and rely on the gravity of self and the impellent of spiral coil cooling tube to move to conical head, discharge product to next procedure through scraper.Part product is got back to the equipment top by the crystal seed circulation line and is entered housing as crystal seed, and the required crystal seed in the back of driving is supplied with by the equipment self circulation, and crystallisation process is realized serialization.
Xylose production vertical continuous crystallizer of the present utility model is compared with prior art, has following characteristics:
(1) having solved xylose crystalline production can not the successive problem, has realized that the turnover of material is continuous, guarantees that the serialization of producing carries out.
(2) multilayer coil pipe gradient cooling, material lowering temperature uniform, controlled, crystallization effect is good.
(3) reduce working strength of workers.
