Abstract

The invention relates to a steam condensate waste heat recovery device. The steam condensate waste heat recovery device comprises a vacuum condenser, a heater, a centrifugal steam dispersing device, a water tank, a constant-pressure drainage tank and a multilevel drainer, a lower portion of the vacuum condenser is communicated with a lower portion of the heater through an ammonia gas pipe, an upper portion of the heater is communicated with an upper portion of the centrifugal steam dispersing device through a steam pipe, the lower portion of the heater is also communicated with a lower portion of the centrifugal steam dispersing device through a first drainage pipe, and the upper portion of the centrifugal steam dispersing device is also communicated with the water tank through a connection pipe. Compared with the prior art, the steam condensate waste heat recovery device has the advantages that the heater is capable of utilizing steam heat obtained from self-steaming to heat sugar juice, and by means of making full use of waste heat to heat the sugar juice, continuous production and use by the waste heat is realized, high self-steaming efficiency is realized, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery, in particular to a steam condensate waste heat recovery device. Background technique [0002] During the production process of the sugar factory, a large amount of water in the sugar juice is evaporated, and the sugar juice can only be crystallized after it is concentrated. , and the temperature of these condensed water is as high as 90-95 degrees, which has more energy. Many sugar factories directly discharge the condensed water into the circulating water pool, without fully recovering the remaining heat, resulting in a great waste of energy. At the same time, it also increases the burden of cooling treatment of circulating water and increases power consumption. At present, there is also a method of directly heating low-temperature sugarcane juice with high-temperature condensed water to make full use of the waste heat of high-temperature condensed water. However, due to the low hea...
