Abstract

本实用新型公开了一种逆流冷凝真空器,包括桶体、射水筒和喷雾筒,其特征在于喷雾筒与射水筒为两个独立构件,喷雾筒设置在射水筒的上方,沿喷雾筒体的轴线设置有多层辐射状支管,支管的顶端安装有喷雾嘴,射水筒下部设置有多个射水嘴,所有射水嘴的中心线在一定的距离外聚焦,射水筒和喷雾筒各有进水管与桶体外的滤水筒相连。工作时,其喷出的水雾与反向流入雾腔的汁汽起逆流冷凝作用,经冷凝的热汁汽急剧冷缩,达到冷凝和抽真空的目的。此种结构的工作过程为两次抽空过程。本实用新型由于冷凝过程为逆流冷凝,因此冷凝效果更好,抽空速度更快,真空度更高,用水量更少,适用于糖厂煮糖罐、蒸发罐和各种蒸汽蒸发过程的冷凝和抽真空。
The utility model discloses a reflux condensation vacuum device, comprising a barrel body, a water injection cylinder and a spraying cylinder. The utility model is characterized in that the spraying cylinder and the water injection cylinder are two independent components; the spraying cylinder is arranged above the water injection cylinder; a plurality of layers of radial manifolds are arranged along an axis line of the spraying cylinder; the top of the manifold is provided with a spraying nozzle; the lower part of the water injection cylinder is provided with a plurality of water injection nozzles; the central lines of all water injection nozzles are focused outside a certain distance; the water injection cylinder and the spraying cylinder are respectively provided with a water inlet cylinder connected with a water filter cylinder outside the barrel body. When in working, the sprayed water mist has a reflux condensation function with the liquor reversely flowing into a mist chamber; the hot liquor is sharply contracted by the condensation, thus reaching the condensation and vacuum pumping aims. The working process of the structure is divided into two pumping processes. Owning to the reflux condensation of the condensation process, the utility model has the advantages of better condensation effect, faster vacuum pumping speed, higher vacuum degree, less water dosage and being suitable for the condensation and vacuum pumping of sugar bowls in sugar factories, vaporization tanks and all steam vaporization processes.
