Abstract
The utility model discloses a film evaporator which comprises a box body, wherein a feeding opening and a vacuum air exhausting opening are formed in the top of the box body; a discharging opening is formed in the bottom of the box body; a steam inlet and a steam outlet are formed in the sidewall of the box body; a distribution tray is close to the feeding opening inside the box body; a distributor is arranged below the distribution tray; the distributor is arranged in an upper opening of a heat exchange tube bundle; a lower opening of the heat exchange tube bundle is communicated with the discharging opening. The film evaporator disclosed by the utility model enlarges a heat contact surface between a material and steam, increases water evaporation speed of the material, can concentrate the material after the material is charged through a heat exchange tube and discharged from the heat exchange tube, thereby ensuring the subsequent usage of the material, also effectively improving the utilization efficiency of the steam, and saving energy.
Description
Technical field
The utility model relates to evaporation equipment field, particularly a kind of thin film evaporator.
Background technology
Evaporation is a kind of technique common in industry; The object of evaporation is that the moisture vaporization in material is removed, to be concentrated into the concentration needing, the heat energy of evaporation is supplied with by heating steam, therefore, evaporimeter, as the visual plant in the industry production such as chemical industry, medicine, food, is widely used in each field.The steam consumption that existing evaporimeter uses in evaporation process is very large, relatively wastes energy, and poor to material film-formation result when entering in heat exchanger tube, caused material contained humidity evaporation efficiency lower, the problem that the product quality of formation is not good.
Utility model content
The problem that the utility model solves is to provide a kind of thin film evaporator, solves the not good problem of existing evaporimeter result of use.
For addressing the above problem, the technical solution adopted in the utility model is:
A kind of thin film evaporator, comprise casing, described casing top is provided with charging aperture and vacuum pumping opening, bottom are provided with discharging opening, described wall box is provided with steam inlet and steam (vapor) outlet, described box house is provided with distributing disc near charging aperture place, below described distributing disc, be provided with distributor, described distributor is positioned at the upper port place of heat-exchanging tube bundle, and described heat-exchanging tube bundle lower port is communicated with discharging opening.
Further, described distributing disc is closely fixed on described cabinet wall, and its card is distributed with multiple through holes.
Further, the cross section of described distributor is annulus, and has barrier sheet in the middle of annulus.
Further, the heat exchanger tube internal coat of described heat-exchanging tube bundle has anticorrosive coat.
Further, described casing outer setting has heat-insulation layer.
Further, described heat-exchanging tube bundle is comprised of spiral heat exchange tube.
Further, between described heat-exchanging tube bundle and described cabinet wall, be provided with steam deflector
Compared with prior art, the advantage of technical solutions of the utility model is:
By setting gradually distribution plate, distributor near the charging aperture in casing, the material that charging aperture is come in is evenly distributed to heat exchanger tube fast by distribution plate and distributor, and form film-form at heat exchange tube wall, under Action of Gravity Field, flow downward, thereby increase the thermal interface of material and steam, improve the moisture evaporation rate of material, not only can make material enter to have concentrated out time to heat exchanger tube from heat exchanger tube, guarantee the follow-up use of material, and effectively improved the utilization ratio of steam, saved the energy.
Accompanying drawing explanation
Fig. 1 is the utility model specific embodiment schematic diagram.
Fig. 2 is the utility model specific embodiment distributor schematic diagram.
Fig. 3 is the utility model specific embodiment spiral heat exchange tube schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
As shown in Figure 1, a kind of thin film evaporator, comprise casing 1, described casing 1 top is provided with charging aperture 11 and vacuum pumping opening 12, bottom are provided with discharging opening 13, described casing 1 sidewall is provided with steam inlet 14 and steam (vapor) outlet 15, and described casing 1 is inner is provided with distributing disc 2 near charging aperture 11 places, and described distributing disc 2 is provided with distributor 3 below, described distributor 3 is positioned at the upper port place of heat-exchanging tube bundle 4, and described heat-exchanging tube bundle 4 lower port are communicated with discharging opening.
Wherein, described distributing disc 2 is closely fixed on described casing 1 inwall, and its card is distributed with multiple through holes 21.Described distributing disc 2 carries out face distribution by the through hole 21 that is evenly distributed on card by the material that enters casing 1, makes material can disperse as far as possible to enter heat-exchanging tube bundle 4.
Wherein, the cross section of described distributor 3 is annulus 31, and has barrier sheet 32 in the middle of annulus 31.Described distributor 3 is circular by being again dispersed into by the material of distributing disc 2 through holes 21, and material is trickled along the inwall of heat exchanger tube as far as possible, thereby increases the thermal interface of material and steam, improves heat exchange efficiency.
Wherein, the heat exchanger tube internal coat of described heat-exchanging tube bundle 4 has anticorrosive coat (not shown).Described anticorrosive coat can slow down the corrosion of material to tube wall, improves the service life of heat exchanger tube.
Wherein, described casing 1 outer setting has heat-insulation layer 5.
Wherein, described heat-exchanging tube bundle 4 is comprised of spiral heat exchange tube 41.Spiral helicine heat exchanger tube 41 not only makes its surface area increase, and in limited box height, make the stroke of material longer, thereby make material carry out more fully heat exchange with steam, and then material can be concentrated fully when heat-exchanging tube bundle 4 upper port drop down onto lower port, guarantee that the subsequent treatment of material can be carried out smoothly.
Wherein, between described heat-exchanging tube bundle 4 and described casing 1 inwall, be provided with steam deflector 6.Described steam deflector 6 is on casing 1 inwall between steam inlet 14 and steam (vapor) outlet 15, it is arranged alternately by plurality of plates, after guiding steam is entered by steam inlet 14 around heat-exchanging tube bundle 4 from top to bottom spiral enter steam (vapor) outlet 15 and go out, so, just can make steam contact heat-exchanging tube bank 4 more fully, and then improve heat exchange efficiency.Further, steam deflector 6 can also be fixed on casing 1 by one end, one end is fixed on heat-exchanging tube bundle 4, and heat-exchanging tube bundle 4 is fixed in casing 1 more firmly.
Thin film evaporator described in the utility model, by setting gradually distribution plate near the charging aperture in casing, distributor, the material that charging aperture is come in is evenly distributed to heat exchanger tube fast by distribution plate and distributor, and form film-form at heat exchange tube wall, under Action of Gravity Field, flow downward, thereby increase the thermal interface of material and steam, improve the moisture evaporation rate of material, not only can make material enter to have concentrated out time to heat exchanger tube from heat exchanger tube, guarantee the follow-up use of material, and effectively improved the utilization ratio of steam, saved the energy.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not departing from spirit and scope of the present utility model; can make possible variation and modification, the scope that therefore protection domain of the present utility model should be defined with the utility model claim is as the criterion.
