Problems solved by technology

[0004] At the same time, due to the huge power consumption of polysilicon production, polysilicon manufacturers will build thermal power plants at the same time and use steam to generate electricity to provide electricity. They cannot use the condensate after polysilicon production and utilization to reduce resource consumption in thermal power plants, resulting in higher production costs for thermal power plants.

Abstract

The invention provides a condensate recovery and recycling system. The condensate recovery and recycling system comprises a detection device, a purifying device, a recovery device, a discharge device and a control device. The detection device is used for detecting impurity content of the condensate. The control device is used to determine whether the detection result is in a detection range. The purifying device is used for purifying the condensate. The recovery device is used for recovering and treating the purified condensate. The discharge device is used for discharging the condensate. Through the condensate recovery and recycling system, the recycled condensate is purified, is input into a recycling system and then is recycled.

Description

technical field [0001] The invention relates to the field of chemical production, in particular to a condensate recycling system. Background technique [0002] In the field of polysilicon production, since the production process of polysilicon requires a high temperature and high pressure environment, it is necessary to configure a circulating cooling system to cool down the production equipment to ensure the normal operation of the equipment. At present, the way of condensate circulation is mostly used to cool down the production equipment. The condensate can be cooling water or freon. Because the cost of freon is high, and 7 ℃ cooling water is very easy to obtain in the production of polysilicon, so in actual production Generally, cooling water at 7°C is used as the condensate. [0003] However, due to the leakage of raw materials is easy to occur in the polysilicon production process, after the leaked raw materials enter the circulating condensate, the recycled condensat...
