立式冷凝器在冷库中使用最为广泛,它靠分水头将冷却水呈水膜状旋转下流散布于管壁,在自然下落过程中传导出工质的热量。立式冷凝器在使用中,也常常由于分水头损坏,进水孔堵塞,水量分布不匀,以及管壁结垢锈蚀等原因,造成冷却水垂直下落,换热过程不充分,导致了冷凝效果降低,冷凝压力升高。为此,冷库每年都要耗费相当的人力物力用于冷凝器的维护保养。单以管壁结垢来说,生成的坚硬水垢管道清洗机有时难于清除。而化学清洗则由于存不住水不好进行。天
Vertical condenser in the cold storage is the most widely used, it is by sub-head cooling water was film-like rotation down the spread in the wall, the process of natural convection in the heat of the working medium. Vertical condenser in use, but also often due to sub-head damage, water inlet blocked, uneven water distribution, and corrosion and other causes of scaling corrosion, resulting in vertical cooling water, heat exchange process is not sufficient, resulting in condensation Reduce, condensing pressure rises. To this end, cold storage each year to spend considerable human and material resources for condenser maintenance. Single scale scaling, the resulting hard scale pipeline cleaning machine is sometimes difficult to remove. The chemical cleaning is not good because of water can not keep. day
