布膜器

Filming device

Abstract

本发明公开了一种管式换热器用的布膜器,其结构为:在管式换热器的管板上方有下层料池(8),在下层料池(8)的上方有上层料池(6),在上层料池(6)的中间有中间下料通道(7),在下层料池(8)上有布膜头(9)。布膜头(9)由钢筒、筋板、钢管、堵头组成,钢管通过筋板与钢筒连接,钢管与堵头连接。钢管与堵头通过螺纹连接。在堵头穿过钢管的上部有锁紧螺母。本布膜器能将物料平缓、均匀地分布到管板上,并使料液能均匀地溢流到换热管的管内壁上形成一层均匀液膜,换热效果更好,换热效率更高;同时延长了管板、换热管及换热器的使用寿命。
The invention discloses a filming device for a tubular heat exchanger, comprising a lower feed liquid tank (8), an upper feed liquid tank (6), a middle discharge passage (7) and a filming head (9). The lower feed liquid tank (8) is arranged above a tubular plate of the tubular heat exchanger; the upper feed liquid tank (6) is arranged above the lower feed liquid tank (8); the middle discharge passage (7) is arranged in the middle of the upper feed liquid tank (6); the filming head (9) is arranged on the lower feed liquid tank (8) and comprises a steel cylinder, a reinforcing plate, a steel tube and a plug; and the steel tube is connected with the steel cylinder by the reinforcing plate and is in threaded connection with the plug, and the upper part of the plug penetrating through the steeltube is provided with a locking nut. The filming device enables feed liquid to be smoothly and uniformly distributed on the tubular plate and uniformly overflow to the tubular inner wall of a heat-exchanging tube to form a uniform liquid film, has better heat-exchanging effect and higher heat-exchanging efficiency and prolongs the service life of the tubular plate, the heat-exchanging tube and the heat exchanger.
