Problems solved by technology

The structure of the evaporator adopts the upper water distribution structure, the raw material water is easy to form part of the falling film flowing down the tubes, part of the water column flows down in the tubes, and part of the tubes are short of water, resulting in uneven distribution of raw material water in each tube, and The steam pressure of the boiler is unstable, and the output of the secondary steam is also unstable. Under the fluctuation of the back pressure of the secondary steam, the raw material water flows down in the tubes intermittently. In addition, it is affected by the evaporator Due to the limitatio

Embodiment Construction

[0013] Before use, the figure 1 Or the multiple effects of the present invention shown in 2 are used in series to improve the production efficiency of distilled water.

[0014] When in use, inject high-temperature industrial steam into the evaporation chamber 5 of the evaporation section 3 through the steam inlet 15, and the high-temperature steam will quickly heat up the tubes 4 in the evaporation section 3, and at the same time, the raw material water passes through the rising film water chamber 13 The water inlet 12 enters the rising film water chamber 13, and quickly fills the rising film water chamber 13, because the raw material water rises at the same time at the same level, so it rises rapidly and evenly along the tubes 4 of each rising film part, And as it rises, it is vaporized in some of the tubes 4 of the rising film group, and the vaporized mixture of steam and water moves up quickly along the tubes 4, and the raw material water that is not completely vaporized en...

Abstract

The invention is a climbing film water evaporator, relating to water evaporating device field. It includes evaporator and matchable pipes. The character lies in: the evaporator body is made up of two segments, the upper one is steam and water separation segment, the lower is evaporating segment. The invention makes the water distribution in climbing film pipes even, and it uses double-evaporation structure, the use factor of heat is upgraded greatly, the evaporator works stably, it can upgrade the efficiency of evaporated water, and reduces the cost.

Description

technical field [0001] The invention relates to the field of water distillation equipment, in particular to a rising film water distribution evaporator. Background technique [0002] At present, the equipment for producing medical distilled water generally adopts multi-effect distilled water machines. The distilled water machine is connected in series by multi-effect evaporators. Most of the structures of the evaporators in the prior art are that the upper section is a water distribution section, and the lower section is an evaporation section. The structure of the evaporator adopts the upper water distribution structure, the raw material water is easy to form part of the falling film flowing down the tubes, part of the water column flows down in the tubes, and part of the tubes are short of water, resulting in uneven distribution of raw material water in each tube, and the affected The steam pressure of the boiler is unstable, and the output of the secondary steam is also ...
