Built-in deaerator
Pressure vessel (yālì ró ng qì), English: pressure vessel refers to a closed device that contains gas or liquid and carries a certain pressure. In order to implement scientific management and safety inspection more effectively, pressure vessels are divided into three categories according to working pressure, medium harmfulness and its role in production in China's Pressure Vessel Safety Supervision Regulations. And for each category of pressure vessels in the design, manufacturing process, as well as inspection items, content and methods to make different provisions. Pressure vessels have implemented the safety and quality licensing system for imported goods, and goods that have not obtained the import safety and quality license are not allowed to be imported. According to the latest TSG21-2016 "Safety and Technical Supervision Regulations for Fixed Pressure Vessels", it should be divided into the first group of media and the second group of media according to the media, and then classified into categories I, II and III according to the pressure and volume. The so-called first, second and third categories of the old capacity regulations are no longer applicable.
A pressure vessel is a closed container that can withstand pressure. The use of pressure vessels is extremely wide, it has an important position and role in many sectors such as industry, civil, military and many other fields of scientific research. Among them, the pressure vessels used in the chemical industry and petrochemical industry are the most, and the pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. Pressure vessels are mainly used for heat transfer, mass transfer, reaction and other technological processes in the chemical and petrochemical fields, as well as storage and transportation of pressurized gases or liquefied gases; they are also widely used in other industrial and civil fields, such as air compressors. All kinds of special compressors and auxiliary machines of refrigeration compressors (coolers, buffers, oil-water separators, gas storage tanks, evaporators, liquid coolant storage tanks, etc.) are pressure vessels.

Product introduction:
The deaerator is a kind of hybrid heater in the steam turbine regenerative system. It uses the intermediate extraction steam of the steam turbine to heat the boiler feed water to the saturation temperature under the working pressure of the deaerator to remove dissolved oxygen and other non-condensable gases in the water, prevent or slow down the corrosion of the boiler, steam turbine and its pipelines, and extend The service life ensures the safe operation of the power plant. The operation of the deaerator adopts the physical deaeration method, which is divided into two stages, the primary deaeration stage and the deep deaeration stage. The primary deaeration stage is completed by the spray device. Under various working conditions, the spray device can fully atomize the condensed water, fully contact with the steam, and heat it to the saturation temperature. In the saturated state, oxygen and non-condensable gas are separated out from the water, enter the steam space, and gather near the spray device. When the separated oxygen accumulates to a certain concentration, it is discharged from the running oxygen outlet together with a small amount of steam. The deep deaeration stage is achieved by injecting the main steam into the lower part of the water tank. Depending on the steam in different situations, pressurized hot water and steam/water mixture can all act as the deaeration medium.
The main forms of deaerator are atmospheric (low pressure) deaerator and pressure (high and medium pressure) deaerator, and the operation mode is divided into constant pressure and sliding pressure.
