Abstract
The invention discloses a film distributing device for a horizontal tube type spraying falling-film evaporator, which comprises a spray pipe and a plurality of nozzles on the spray pipe. In the device, a plurality of spray pipes are arranged on the periphery of a heat pipe bundle of the horizontal tube type spraying falling-film evaporator, when the number of the spray pipes is 3, the spray pipes enclosing the heat pipe bundle of the horizontal tube type spraying falling-film evaporator are distributed in an included angle of 120 degrees, wherein one spray pipe is positioned right above the heat pipe bundle of the horizontal tube type spraying falling-film evaporator; the nozzles are fog-shaped nozzles. The spray pipes and nozzles are arranged around the heat pipe bundle of the horizontal tube type spraying falling-film evaporator in a multidirectional manner, so the film on the surface of the heat pipe under the evaporator can be distributed uniformly, film drying and film cracking can be avoided, and the efficiency of the evaporator can be improved.
Description
Technical field
The present invention relates to sprinkling falling-film evaporator, refer more particularly to the film-distributing device of horizontal tube sprinkling falling-film evaporator.
Background technology
Sprinkling falling-film evaporator is used for the concentration and evaporation of various materials such as beverage, medicine, aluminium oxide etc.The nozzle of sprinkling falling-film evaporator sprays the cloth film on the heating tube bundle surface with material; Yet traditional spray film-distributing device is arranged on the heating tube bundle top; The material that sprays out is prone to cause lower heating Guan Shangbu film inequality or does not have the cloth film through the heating tube that is difficult to arrive the bottom that stops of numerous heating tubes, dry film, disconnected film occur; Reduce evaporator effectiveness, influence product quality.
Summary of the invention
Technical problem to be solved by this invention is: the film-distributing device that the horizontal tube sprinkling falling-film evaporator of the comprehensive even cloth film of a kind of ability is provided.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
The film-distributing device of horizontal tube sprinkling falling-film evaporator comprises: shower, be arranged on the plurality of nozzles on the shower, it is characterized in that: a plurality of showers are installed in around the heating tube bundle of horizontal tube sprinkling falling-film evaporator.Said shower number is 3 o'clock, and shower becomes 120 degree angles to distribute around the heating tube bundle of horizontal tube sprinkling falling-film evaporator, and wherein a shower is positioned at directly over the heating tube bundle of horizontal tube sprinkling falling-film evaporator.
Described nozzle is vaporific nozzle.
The invention has the beneficial effects as follows: the shower of multi-faceted setting and nozzle make that the heating tube surface ability cloth film of evaporimeter bottom is even around the heating tube bundle of horizontal tube sprinkling falling-film evaporator, have avoided dry film, disconnected film, have improved evaporator effectiveness.
Description of drawings
Fig. 1 is a main TV structure sketch map of the present invention.
Fig. 2 is a shower installation site sketch map.
Among Fig. 1 to Fig. 2: 1. shower, 2. vaporific nozzle, 3. heating tube bundle.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
Shown in Figure 2 like Fig. 1, the film-distributing device of horizontal tube sprinkling falling-film evaporator of the present invention comprises three showers 1, is arranged on the some vaporific nozzle 2 on the shower 1.The heating tube bundle 3 one-tenth 120 degree angle of three showers 1 around the horizontal tube sprinkling falling-film evaporator distributed, and wherein a shower 1 is positioned at directly over the heating tube bundle 3 of horizontal tube sprinkling falling-film evaporator.Some vaporific nozzles 2 are set on every shower 1.
During use, material carries out the cloth film from different perspectives through the vaporific nozzle 2 on the shower 1 on the heating tube bundle 3 of horizontal tube sprinkling falling-film evaporator.Because multi-faceted shower 1 and the nozzle 2 of being provided with around the heating tube bundle 3 of horizontal tube sprinkling falling-film evaporator makes that the heating tube surface ability cloth film of evaporimeter bottom is even, avoided dry film, disconnected film, improved evaporator effectiveness.
