Closed water circulation cooler
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 The so-called first, second and third categories of the old capacity regulations are no longer applicable.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.
Key words:
Closed water circulation cooler
Closed water circulation cooler
Classification:
Product Introduction
closed circulating water heat exchanger]
Product features:
Effectively prevent the chiller condenser, heat exchanger blockage, prolong the service life of the chiller, reduce the use of water treatment chemicals, than the open cooling tower water loss reduction.
Product introduction:
1. Scope of application: The closed circulating cooling water heat exchanger is mainly used for the cooling of closed circulating cooling water in power plants. The circulating cooling water of the power plant is cooled by the open-type water of the heat exchanger and then provides cooling water to each power plant equipment of the closed cooling system.
2. Structural characteristics
2.1 generally use shell-and-tube structure.
The 2.2 closed circulating cooling water generally goes through the shell side and the open cooling water goes through the pipe side (except for special cases).
The interface of 2.3 closed circulating cooling water heat exchanger is generally set up as follows: inlet and outlet of shell-and-tube side fluid; Shell-and-tube side safety valve interface; Shell-and-tube side exhaust and liquid discharge interface; Temperature and pressure measuring ports at the inlet and outlet of shell-and-tube side fluid.
