Problems solved by technology

The nozzle of the spray falling film evaporator sprays the material on the surface of the heating tube bundle. However, the traditional spraying film device is set above the heating tube bundle. The sprayed material is difficult to reach the lower heating tube after being blocked by many heating tubes. , it is easy to cause uneven or no film distribution on the lower heating tube, dry film and broken film appear, reduce the efficiency of the evaporator, and affect the product quality

Embodiment Construction

[0011] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] Such as figure 1 figure 2 As shown, the film distribution device of the horizontal tube spray falling film evaporator according to the present invention includes three spray pipes 1 and several mist nozzles 2 arranged on the spray pipes 1 . Three spray pipes 1 are distributed at an angle of 120 degrees around the heating tube bundle 3 of the horizontal tube spray falling film evaporator, and one of the spray tubes 1 is located at the front of the heating tube bundle 3 of the horizontal tube spray falling film evaporator. above. Several mist nozzles 2 are arranged on each spray pipe 1 .

[0013] When in use, the material spreads film on the heating tube bundle 3 of the horizontal tube spray falling film evaporator through the mist nozzle 2 on the spray pipe 1 from different angles. Since the spray tube 1 and the nozzle 2 are arrange...

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 [0001] The invention relates to a spray falling film evaporator, in particular to a film distribution device for a horizontal tube spray falling film evaporator. Background technique [0002] The spray falling film evaporator is used for the concentrated evaporation of various materials such as beverages, medicines, alumina, etc. The nozzle of the spray falling film evaporator sprays the material on the surface of the heating tube bundle. However, the traditional spraying film device is set above the heating tube bundle. The sprayed material is difficult to reach the lower heating tube after being blocked by many heating tubes. , It is easy to cause uneven or no film distribution on the lower heating tube, dry film and broken film appear, reduce the efficiency of the evaporator, and affect the product quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a film distribution device for a horizo...
