Product Description
Horizontal high temperature positive displacement heat exchanger
Heat exchanger is a kind of equipment that transfers part of the heat of hot fluid to cold fluid, also known as heat exchanger. Heat exchanger plays an important role in chemical, petroleum, power, food and many other industrial production. It can be widely used as heater, cooler, condenser, evaporator and reboiler in chemical production.
Heat exchanger is a kind of energy-saving equipment to realize heat transfer between two or more fluids with different temperatures. It is to transfer heat from the fluid with higher temperature to the fluid with lower temperature, so that the fluid temperature can reach the index specified in the process, so as to meet the needs of process conditions. At the same time, it is also one of the main equipment to improve energy utilization. The heat exchanger industry involves more than 30 industries, such as HVAC, pressure vessel, reclaimed water treatment equipment, chemical industry, petroleum and so on, forming an industrial chain with each other. Data show that the market scale of China's heat exchanger industry in 2010 is about 50 billion yuan, mainly concentrated in petroleum, chemical industry, metallurgy, electric power, shipping, central heating, refrigeration and air conditioning, machinery, food, pharmaceutical and other fields. Among them, petrochemical industry is still the largest market of heat exchanger industry, with a market scale of 15 billion yuan; the market scale of heat exchanger in power metallurgy is about 8 billion yuan; the market scale of heat exchanger in shipbuilding industry is more than 4 billion yuan; the market scale of heat exchanger in machinery industry is about 4 billion yuan; the market scale of heat exchanger in central heating industry is more than 3 billion yuan, and that of food industry is nearly 3 billion yuan The market. In addition, aerospace vehicles, semiconductor devices, nuclear power conventional island, nuclear island, wind turbine, solar photovoltaic power generation, polysilicon production and other fields all need a large number of professional heat exchangers. These markets have a scale of about 13 billion yuan. The domestic heat exchanger industry has made remarkable achievements in energy saving and efficiency increasing, improving heat transfer efficiency, reducing heat transfer area, reducing pressure drop and improving heat intensity of the device. Based on the steady growth of heat exchanger demand in petroleum, chemical, electric power, metallurgy, shipbuilding, machinery, food, pharmaceutical and other industries, China's heat exchanger industry will maintain a stable growth in the future. From 2011 to 2020, China's heat exchanger industry will maintain an average annual growth rate of about 10-15%, and the scale of China's heat exchanger industry is expected to reach 150 billion yuan by 2020.
It is suitable for heat exchangers with different media, different working conditions, different temperatures and different pressures, and has different structural types. The specific classification of heat exchangers is as follows:
Installation Instructions
Classification according to heat transfer principle
Inter wall heat exchanger is a kind of heat exchanger in which two kinds of fluids with different temperatures flow in the space separated by the wall, and heat transfer is carried out between the two fluids through heat conduction on the wall and convection on the wall surface. There are shell and tube type, sleeve type and other types of inter wall heat exchanger. The inter wall heat exchanger is the most widely used heat exchanger at present. 2. The regenerative heat exchanger transfers heat from the high temperature fluid to the low temperature fluid through the heat storage body composed of solid materials. The heat medium first reaches a certain temperature by heating the solid materials, and then the cold medium is heated through the solid materials, so as to achieve the purpose of heat transfer. Regenerative heat exchanger has rotary type, valve switching type and so on. 3. Fluid connected indirect heat exchanger fluid connected indirect heat exchanger is a heat exchanger that connects two surface heat exchangers by circulating heat carriers. The heat carrier circulates between the high temperature fluid heat exchanger and the low temperature fluid, receives heat in the high temperature fluid, and releases heat to the low temperature fluid in the low temperature fluid heat exchanger. 4. Direct contact heat exchanger is also known as hybrid heat exchanger, this kind of heat exchanger is two kinds of fluid in direct contact, mixed with each other for heat exchange equipment, such as cold water tower, gas condenser, etc. 5. The compound heat exchanger has two kinds of heat exchange modes: steam surface indirect heat exchange and water water direct mixed flow heat exchange. Compared with steam water surface indirect heat transfer, it has higher heat transfer efficiency; compared with steam water direct mixed heat transfer, it has higher stability and lower unit noise.
Classification by use
1. The heater is to heat the fluid to the necessary temperature, but there is no phase change in the heated fluid.
2. The preheater pre heats the fluid to provide standard process parameters for process operation.
Heat exchanger
3. Superheater superheater is used to heat the fluid (process gas or steam) to superheated state. 4. The evaporator is used to heat the fluid to reach the temperature above the boiling point and make the fluid evaporate, generally with phase change.
By structure
It can be divided into: floating head heat exchanger, fixed tubesheet heat exchanger, U-shaped tubesheet heat exchanger, plate heat exchanger, etc.
