Product introduction

The vacuum deaerator is also referred to as:vacuum jet air exhausting device,vacuum exhausting device,vacuum degassing tank,vacuum degassing device,vacuum degassing unit and vacuum sputtering exhaust device,etc.
If there is gas in the heating and cooling system,the system will generate air resistance easily,so as to block the circulation of the system partially or completely.The increase of air resistance will disable the heating system and the cooling system.At the same time due to the water containing oxygen and makes heating (cooling) equipment,pipes and steel radiators have oxygen corrosion, leading to perforation,leakage.In the system,the gas can also cause the corrosion of the pump, which directly affects the safety of the whole system.Vacuum degassing method is used to remove the free gas and dissolved gas in the system,so that the system can operate safely and reliably.In the circulating water system,many users use the water softener,pump controlled pressurisation system,spiral dirt separator and vacuum deaerator cooperatively,which do not only reduce the scaling,stabilize system pressure and reduce the energy consumption,but also slow down the corrosion,reduce noise and water turbidity.
The vacuum deaerator is a new generation of circulating water system degassing device introduced by Peide Water Treatment Equipment Co., Ltd. from the developed countries,such as United States and England,through adopting world leading vacuum degassing technology.It solves the problems of poor circulation of the partial or entire system caused by gas,noise in the pipe network caused by oxygen,bad heat transfer effect of the heat exchanger in the heating and cooling system.Vacuum deaerator is an important part of the circulating water system.
The vacuum deaerator is widely used in HVAC circulating water system and it can remove the free and dissolved air and oxygen in the water effectively with the degassing efficiency of above 99%,which can solve the problems of air resistance and air block in the pipeline completely,eliminate the noise of pipe network system,slowly down the oxygen corrosion of radiator and pipe significantly,eliminate the cavitation of pump and prolong the service life.

Working principle of vacuum deaerator

According to Henry's law,the solubility of gas in water is related to the water temperature and pressure. At a certain temperature,the pressure of the gas is proportional to the pressure.Under the pressure,the water temperature decreases,the solubility of the gas increases,the water temperature increases and the gas solubility decreases.When the water pressure is reduced,the gas can be dissolved in the water,so that the gas in the water can be removed.Vacuum deaerator is through the generation of vacuum,the free gas and dissolved gas released from the water,and then through the automatic exhaust valve system,the water re injection system.These low water volume of water is unsaturated water and is highly absorbent of gas,it will absorb gas system so as to achieve a balance between water and gas.Vacuum deaerator to repeat such a cycle every 20~30 seconds.Most gas of the system will be removed by adopting such circulation.

Working process of vacuum deaerator 

1.When the water pump is running,the water enters into the water inlet through sputtering mode. The water level of the tank is dropping to form vacuum state in the degassing tank. 2.When the water pump is running,the water enters into the water inlet through sputtering mode.The gas is separated from the water and exhausted through the vent valve because of negative pressure.The water level of the degassing tank is dropping continuously.

1.When the water level of the degassing tank drops to the alarm level,the water pump will stop. The water enters into the water inlet continuously and the gas is removed.
2.After the setting time, the water pump is turned on and continues to pump the vacuum.Then it will enter into the next operation cycle.
