Shell and Tube Heat Exchanger
Shell types Heat Exchanger are classified into fixed and floating type Heat Exchangers. Fixed type Heat Exchangers are used where there are absolutely no chances for inter mixing of two fluids. In this type, the tube sheets are completely welded to the shell and acted as shell flanges. The Floating type Heat Exchangers has the advantages of removability of tube bundle and access for cleaning both inner and outer side of tubes and shell. BEU heat exchanger are shell and tube exchangers with tube bundle consisting of 'U' shaped tubes fixed by mechanical rolling to only one tube sheet. This type of heat exchangers is designed and built with removable shell and tube to allow easy maintenance.

Principle A plate and frame heat exchanger as known as gasketed plate heat exchanger is a high efficiency heat exchanger that assembled from metal sheets with corrugated pattern and different kind of gaskets. Plate heat exchangers are the ideal equipment for heat exchange between liquid-liquid and liquid-vapor.In the case of the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, but the floor space is one-third of the tube heat exchanger, and the heat recovery rate can be as high as 90% or more. Maximum volume: 5000m3 /h;Maximum design pressure: 25bar Maximum temperature: 200 celsius degree; Minimum difference in temperature: 0.5-1 celsius degree Nozzle diameter: DN15~DN500;Plate thickness: 0.4mm - 1.2mm Gasket material:NBR, EPDM, HNBR, HT-NBR, HEPDM, CR,VITON/FKM Fixed and movable plate material: Carbon Steel, Stainless Steel, and others on request. Plate material:AISI304, AISI316, AISI316L, Titanium,Ti-Pa,Hastelloy C276,254SMO,Nickel, AISI904L. Plate heat exchanger High heat transfer coefficient The design of the plate corrugation is aimed at the high thermal conductivity. The special flow path are formed by the plate corrugation causing strong disturbance flow at a very low flow rate, which is called turbulent flow. And the disturbance flow can be self-cleaning to prevent fouling and thus the heat transfer efficiency is high. Plate heat exchanger Large logarithmic temperature difference The temperature difference at the end is small, and the plate heat exchanger is mostly a cocurrent or countercurrent type of flow. In addition,there's no bypass flow. Plate heat exchanger Small footprint and easy maintenance The plate heat exchanger has a compact structure, and the heat exchange area per unit volume is 2-5 times that of the shell-and-tube type, and the floor area of the plate heat exchanger is about 1/2-1/3 of the shell - tube heat exchanger when achieving same heat exchange capacity .
Removable Plate Heat Exchanger: The Removable plate heat exchanger is a new type of high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between the various plates, and heat is exchanged through the halves. Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-vapor heat exchange. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger, the floor area is one third of that of the tubular heat exchanger, and the heat recovery rate can be as high as 90% or more. This product is suitable for chemical, machinery, food, beverage, medicine, residential heating, hot water supply, air conditioning and other departments. Intermediate heat exchangers used in conjunction with boilers, intermediate heat exchangers in high-rise buildings, etc., soda ash industry, synthetic ammonia, alcohol fermentation, resin synthesis cooling, etc. Detachable plate heat exchanger is a new type of energy-saving heat exchange device with high heat transfer effect, compact structure, small footprint, easy operation, convenient cleaning, disassembly and maintenance, and easy to change the heat exchange area or process combination, etc. advantage. 1. The Removable plate heat exchanger has a compact structure with a small footprint, and the heat exchange area per unit volume is 2 to 5 times that of the shell-and-tube type. Unlike the shell-and-tube type, the maintenance site for drawing out the tube bundle is not reserved, so the same For heat exchange, the plate heat exchanger covers an area of â??â??about 1/5~1/8 of the shell and tube heat exchanger. 2. It is easy to change the heat exchange area or process combination. As long as a few plates are added or reduced, the purpose of increasing or reducing the heat exchange area can be achieved; by changing the plate arrangement or replacing a few plates, the required process combination can be achieved. It is almost impossible to increase the heat transfer area of â??â??shell and tube heat exchangers to adapt to new heat exchange conditions. Removable plate heat exchanger is a kind of heat exchanger that is widely used in heat exchangers. It is widely used in chemical, machinery, food, beverage, medicine and other occasions. Users should select and use according to actual needs and the advantages and characteristics of heat exchangers are used to choose, and well-known brand products are also very important.
