Titanium plate heat exchanger is a new type of high-efficiency heat exchanger stacked by a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and thermal energy is exchanged through the plates. Titanium plate heat exchangers, heat exchanger plates commonly used materials are mainly austenitic stainless steel, titanium and titanium alloys, nickel and nickel alloys and other cold-rolled thin plates. Industrial pure titanium 127 is used in plate heat exchangers, industrial pure titanium 276 and Ti-0.3Mo-0.8Ni345 are used in tube heat exchangers. The plate heat exchanger made of TA1 titanium plate has many advantages compared with the tube-and-tube heat exchanger and has a strong competitiveness in the market. It is mainly used in heat exchange systems such as chemical industry, petroleum, ships, and desalination . The plate heat exchanger has the following unique features in design.
(1) High efficiency and energy saving. Its heat transfer coefficient is 3000 ~ 4500 kcal / m2? ℃? H, which is 3 ~ 5 times higher than the heat efficiency of the shell and tube heat exchanger.
(2) Compact and close. The plate heat exchanger has a precise arrangement of plates. Compared with other heat exchanger types, the plate heat exchanger occupies less floor space and occupies less space. The area of a plate heat exchanger with the same heat exchange capacity is only the shell and tube heat 1/5 of the device.
(3) Long service life. The plate heat exchanger is pressed by stainless steel or titanium alloy plate, which can withstand all kinds of corrosive media.
(4) Strong adaptability. The plate heat exchanger plate is a self-supporting element, which can be increased or decreased as required. It can be adapted to the requirements of a variety of different processes.
