Problems solved by technology
[0003] 1. Noise pollution. After the deaerator undergoes thermal deoxygenation, it will also discharge part of the steam while discharging the gas. Due to the high pressure of the deaerator, the noise will be louder when the oxygen is discharged, causing noise pollution to the surrounding environment;
[0004] 2. Waste of heat energy, the gas discharged from the deaerator contains steam, and the steam will take away part of the heat energy, resulting in waste of heat energy

The invention discloses a noise reducing and energy saving device applied to a deaerator. The noise reducing and energy saving device applied to the deaerator comprises a heat exchanger, a first pipeline, an exhaust fan, a second pipeline, a demineralized water main pipe, a third pipeline, a fourth pipeline, a sixth pipeline and a demineralized water tank. The heat exchanger communicates with the deaerator through the first pipeline and communicates with the exhaust fan through the second pipeline. The deaerator communicates with a demineralized water isolating valve through the demineralized water main pipe. The section, located between the deaerator and the demineralized water isolating valve, of the demineralized water main pipe communicates with the heat exchanger through the third pipeline. The demineralized water isolating valve communicates with the heat exchanger through the fourth pipeline. The demineralized water isolating valve communicates with the demineralized water tank through the sixth pipeline. Heat exchange between demineralized water from the demineralized water tank and water vapor from the deaerator is conducted inside the heat exchanger, the demineralized water brings away heat energy of the water vapor and goes back to the deaerator, the water vapor cools and coagulates into water which is then discharged out of the heat exchanger, and separated gas is exhausted out of the heat exchanger through the exhaust fan. The noise problem is solved, and meanwhile the heat energy is recycled.
Description
technical field [0001] The invention relates to the technical field of deaerators, in particular to a noise reduction and energy-saving device applied to a deaerator. Background technique [0002] Deaerators in thermal power plants need to discharge oxygen after thermal deoxygenation. Generally, they are evacuated. The main disadvantages are as follows: [0003] 1. Noise pollution. After the deaerator undergoes thermal deoxygenation, it will also discharge part of the steam while discharging the gas. Due to the high pressure of the deaerator, the noise is loud when discharging oxygen, causing noise pollution to the surrounding environment; [0004] 2. Waste of heat energy. The gas discharged from the deaerator contains steam, and the steam will take away part of the heat energy, resulting in waste of heat energy. Contents of the invention [0005] In view of this, in order to solve the problems in the prior art, the present invention proposes a noise reduction and energy ...
