The condenser steam injection mixed heat exchange vacuum system comprises a condenser pipe connected with the condenser and a steam pipe connected with auxiliary steam.

Steam pipes and condenser pipes are connected with steam injectors and vacuum type mixed heat exchange systems. The steam injectors are respectively connected with condenser pipes.

The outlet diffuser pipe at the tail is connected to the inlet of the vacuum type mixed heat exchange system.

the other end of that hybrid heat exchange system is connecte to the water re vacuum pump group, and there are at least two groups of water re vacuum pump groups and are connected to the condenser in parallel

On the pipeline. For the first time, the project innovatively uses condensed water in the condensed water system as cooling water. Compared with open water, its water quality is better.

Avoid fouling problems. At the same time, in order to reasonably control the amount of condensate entering the hybrid heat exchange system, add water to the condensate inlet

The adjusting device automatically controls the flow and pressure according to the heat exchange situation and makes reasonable use of condensed water. The drain of the mixed heat exchange system is connected to the condenser

The hot well eventually returned to the boiler water system, effectively utilizing the heat exchange in the hybrid heat exchanger. Unlike tube heat exchangers

In the method of heat exchange through the pipe wall, the hybrid heat exchange system directly reduces the temperature by mixing cooling water and the exhaust gas from the jet pump

For the purpose of condensation, its heat exchange efficiency is greatly improved and a large amount of cooling water consumption is saved. Cold in a hybrid heat exchange system

However, the water source also uses condensed water different from the tube heat exchanger. Compared with open water, condensed water has a higher quality and contains impurities.

The quality and calcium and magnesium ions that are easy to scale are also lower, which can avoid heat exchange efficiency degradation caused by fouling of heat exchange tubes such as tubular heat exchangers.

Low, a problem that requires frequent cleaning.

The project system (condenser steam injection mixed heat exchange vacuum system) has been developed and successfully operated, and has passed Shanghai quality supervision and inspection.

Tested by the Institute of Technology, its performance meets relevant technical requirements; at the same time, the project technology has been consulted by China Academy of Sciences in Shanghai Science and Technology Novelty Searching

Xinxin believes that it is novel and reaches the domestic leading level; the project has been under the responsibility of China Datang Group Datang Henan Sanmenxia Power Generation Limited

Ren Company, China Power Investment Corporation China Power International Anhui Huainan Pingwei Power Generation Co., Ltd., Jilin Electric Power Co., Ltd. Baicheng Power Generation Company

It was tried by other units, and the reaction effect was good, and the experimental performance and quality were better than the condenser steam injection vacuum system; the core technology of the project system

It is mature and has obtained 1 invention patent authorization. The company has an experienced R & D team and advanced testing equipment

And production equipment can well ensure project implementation.
