Fixed-row and continuous-row flash tank
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 The so-called first, second and third categories of the old capacity regulations are no longer applicable.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
Fixed-row and continuous-row flash tank
Regular blowdown flash tank is to discharge the boiler sewage regularly, and after decompression and expansion, secondary steam and waste hot water are separated. Secondary steam is discharged into the atmosphere or used as a heat source, and waste hot water is generally discharged into the groundwater system through the sewage cooling pool.
The continuous blowdown flash tank is connected with the continuous blowdown outlet of the boiler to reduce the pressure, expand the capacity, and then discharge the continuous blowdown of the boiler. The secondary steam is led out by a special pipeline and generally enters the deaerator. The waste hot water is automatically discharged through the float liquid level valve or the overflow regulating valve, and generally enters the fixed discharge flash tank, so that the heat energy can be recovered and reused. The continuous blowdown amount is automatically adjusted with the change of boiler feed water load to maintain a relatively stable blowdown rate. Secondary steam and waste hot water can be used as heat sources to recover part of the heat lost in continuous blowdown of the boiler and improve boiler efficiency.
