The invention discloses a wave-current valve auto-cleaning-type vertical-pipe falling-film evaporator, wherein a wave-current valve, a coupling spring, and a cleaning spiral are combined to form an auto-cleaning mechanism for removing dirt in a heating pipe. A large pipe section and a small pipe section of the wave-current valve are functional sections of achieving alternate variation between large flow quantity and small flow quantity. Due to the alternate variation, vertical movement with travel ranging from 30-300 mm, auto-rotation with positive / negative angle being 150-1000 degrees, and frequent radial vibration of the cleaning spiral are driven, thereby auto-cleaning the tube. The structure is simple and has strong capability of removing dirt in the heating pipe, can uniformly clean the heating tube and increases the efficiency of the falling-film evaporator, in which dirt is liable to grow in interior of the heating tube, significantly even multiply. The vertical-pipe falling-film evaporator is good in energy-saving effect.
Description
technical field [0001] The invention relates to a vertical pipe falling film evaporator with automatic cleaning of wave flow valve, and mainly relates to the automatic cleaning of the dirt in the heating pipe of the vertical pipe falling film evaporation device and the uniform film distribution of the liquid flow. It is especially suitable for the falling film evaporation device that is easy to grow dirt in the vertical heating tube, and the heat pump vertical tube falling film evaporation device for the easy-scaling solution can greatly improve the production capacity and energy-saving benefits. Background technique [0002] Falling film evaporator, because the liquid film is very thin, the actual liquid film flow rate is fast, the heat transfer efficiency is very high, and the heat transfer coefficient can be as high as 2000-3000 (w / m °C). But the liquid film is very thin, it is easy to dry wall, and it is easier to scale than the forced circulation evaporator. Therefore,...
