Construction of Titanium Plate Heat Exchanger
Titanium plate heat exchanger is a series of a certain corrugated shape of the metal sheet stack made of a new type of high efficiency heat exchanger between the various plates to form a shallow rectangular channel, through the half of the heat exchange with it. Compared with the case of the same flow resistance and pump power consumption, the heat transfer coefficient is much greater than that of the shell and tube heat exchanger, and there is a tendency to replace the shell-and-tube heat exchanger within the applicable scale. Titanium plate heat exchangers, heat exchangers Industry board commonly used materials are mainly austenitic stainless steel, titanium and titanium alloy, nickel and nickel alloy cold-rolled sheet industrial pure titanium 127 for plate heat exchanger, industrial titanium 276 and Ti-0.3Mo-0.8Ni345 for tubular heat exchanger with TA1 titanium plate to build the plate heat exchanger, compared with the tube heat exchanger has many advantages in the market has a strong competitive, mainly with In the chemical, oil, ship, desalination and other hot swap system.
Plate heat exchanger in the design of the following unique:
(1) energy efficiency: the heat transfers coefficient of 3000 ~ 4500 gal / m2? ℃? H, shell heat exchanger than the thermal efficiency of 3 to 5 times higher.
(2) compact and close: plate heat exchanger plate precision arrangement, compared with other types of heat exchanger, plate titanium frame what characteristics of the heat exchanger covers an area and take up less space, the same heat transfer the area of The plate heat exchanger is only 1/5 of the shell-and-tube heat exchanger.
(3) easy to clean Disassembly convenience: plate heat exchanger clamped by the clamping plate clamping plate, so easy disassembly, any time to open the cleaning, and because the board smooth, turbulent deep, straightforward to scale.
(4) no string of liquid, plate heat exchanger seal groove set leeward, a variety of media will not be collusion, even if there is leakage, the media is always out.
(5) long service life: plate heat exchanger with stainless steel or titanium plate to suppress, can withstand a variety of corrosive media. Pads can be changed in heart, and can facilitate the disassembly maintenance.
(6) muscular adaptability: plate heat exchanger plate for the self-force components, according to the requirements of the heart increase or decrease the process, the situation is diverse; applicable to a variety of different process requirements.
Titanium plate heat exchanger basic structure: titanium plate heat exchanger mainly by the frame and titanium plate 2 mostly constitute the plate is made of various materials made of thin plate with a variety of different conditions of the production model into the shape of the individual Corrugated, and in the corners of the plate 4 corners open hole for the media flow path plate around the corner and the corner with a rubber gasket to seal the frame by the fixed compression plate, playing the compression plate, the upper and lower guide And clamping bolts, etc. constitute a plate heat exchanger is the plate in a superposition of the situation in the fixed compression plate, the middle of the compression plate, and then clamped with clamping bolts.
The MSF unit with the largest single volume is produced, with a focus of 36,000 t / d. The installation of the Titanium Plate Heat Exchanger in Italy is an efficient, compact and close heat exchanger that was developed as a continuous low temperature sterilizer in the 1880s. , To the 20th century, 20 years began to apply to the food industry Titanium plate heat exchanger in the construction and application of some peculiar, therefore, the current plate heat exchanger has been widely used in petroleum, chemical, light industry, power, smelting Metal, machinery, energy and other industrial areas, a very influential family of heat exchanger family of our country from the 20th century, 60 years began to produce plate heat exchanger, until now the plate heat exchanger in many areas of China have been extensive The application of titanium and titanium alloy is a recent rise of the promising metal materials, made of titanium heat transfer with good corrosion resistance, high heat transfer efficiency, smooth surface without cracks, the proportion of small, high strength, equipment Volume and quality of small and so unique, widely used in aviation, space research and development, marine engineering, petroleum, chemical, metallurgical metals, electronics, medical drugs health, food Processing, instrumentation, and other visible spectrograph.
