Embodiment Construction

[0011] In conjunction with the accompanying drawings, the overall structure of the present invention and its working principle are described in detail:

[0012] The waste heat combined steam jet vacuum pump system that can be used includes the existing steam jet vacuum pump unit, especially after the first, second, third, fourth or fifth stage ejector of the steam jet vacuum pump unit Add an ejector and condenser between the condenser and the ejector and condenser group behind it, wherein the ejector and condenser group are one group, two groups, three groups or four groups, on the condenser in front of an ejector It is connected with a water ring vacuum pump to form a new steam jet vacuum pump unit. The new steam jet vacuum pump unit is equipped with an absorption refrigerator, a water separation drum, a steam distribution drum and a waste heat source device. As shown in Figure 1, it provides a specific embodiment of the present invention. From the existing steam jet vacuum ...

Abstract

The invention relates to a combined steam injection vacuum pump system capable of utilizing waste heat which is used in a production technique of industrial production needing to obtain vacuum and refining products in vacuum. The combined steam injection vacuum pump unit is mainly formed by the existing steam injection vacuum pump set, especially by additionally arranging a jet apparatus and a condenser between a condenser 5 which is behind the first, the second, the third, the fourth or the fifth grade jet apparatus of the steam injection vacuum pump unit and a jet apparatus and a condenser set which are behind the condenser 5, connecting a water ring type vacuum pump in parallel with the condenser in front of one jet apparatus to from a novel steam injection vaccum pump set and arranging a suction type refrigeration apparatus, a water dividing packet, a steam dividing packet and a waste heat source device on the novel steam injection vacuum pump set. The combined steam injection vacuum pump system capable of utilizing waste heat integrates all the advantages of the existing steam injection vacuum pump and overcomes potential defects thereof by the comprehensive design and not only achieves the effects of energy saving and exhaustion reducing, but also ensures the long period reliability and stability needed by large industrial production.

Description

technical field [0001] The invention relates to a waste heat combined steam jet vacuum pump system, which belongs to the technical scope of power machinery. It is used in industrial production processes where it is necessary to obtain a vacuum and refine the product under vacuum. For example, the out-of-furnace refining of special molten steel, the refining process of edible oil, the molecular distillation of biopharmaceuticals, and the vacuum sublimation drying of food, etc. Background technique [0002] There are more than 10,000 steam jet vacuum pumps in operation in China's industrial production, most of which are pure steam jet vacuum pump systems. There are also 5--10% water ring-steam jet vacuum pump system. The pure steam jet vacuum pump is characterized by a simple structure, almost no maintenance, once debugged and used, it can run continuously for a long time without failure. Its main disadvantages are large consumption of steam and cooling water, resulting in ...
