Structure overview of titanium heat exchanger

Titanium heat exchanger is a new type of high efficiency heat exchanger made of a series of corrugated metal sheets stacked into a thin rectangular channel between various sheets, through the process of heat exchange of half a sheet it and the general tube and shell heat exchanger compared with the same flow resistance and pump power consumption, the heat transfer coefficient is much higher, There is a trend to replace shell and tube heat exchangers at suitable scales. Titanium plate heat exchanger, heat exchanger industry plate 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 pure titanium 276 and Ti-0.3Mo-0.8Ni345 for tube heat exchanger with TA1 titanium plate made of plate heat exchanger, Compared with tubular heat exchanger has many advantages, has a strong competitiveness in the market, mainly used in chemical industry, petroleum, ships, seawater desalination and other heat exchange system.

The design of plate heat exchanger mainly has the following unique features:

(1) High efficiency and energy saving: its heat transfer coefficient is 3000 ~ 4500 kcal/m2? ℃? h, the thermal efficiency is 3~5 times higher than that of shell and tube heat exchanger.

(2) Compact and close: plate heat exchanger plate precision arrangement, compared with other heat exchanger types, plate pure titanium frame what characteristics of the heat exchanger covers an area and occupies less space, the same heat exchanger area of the plate heat exchanger is only 1/5 of the tube and shell heat exchanger.

(3) Easy to clean and disassemble and assemble: plate heat exchanger by clamping bolt clamping plate clamping, so easy to disassemble and assemble, can be opened at any time cleaning, at the same time because the surface is smooth, turbulence deep, not easy to scale.

(4) Do not string liquid, plate heat exchanger sealing groove set up drain, all kinds of media will not collude, even if the emergence of leakage, the media is always discharged to the outside.

(5) Long application life: plate heat exchanger is made of stainless steel or titanium alloy plate pressing, can withstand all kinds of decay media, rubber pad can be changed, and can be easily disassembled and repaired.

(6) Strong adaptability: plate heat exchanger plate is a self-reliant component, can be according to the requirements of the flow, the situation is diverse; Can be applied to various different process requirements.

The basic structure of titanium plate heat exchanger: Titanium plate heat exchanger is mainly composed of frame and titanium plate 2 mostly plate is made of a variety of materials made of thin plate with a variety of different situations of production model pressed into different shapes of corrugated, and in the plate 4 corners open corner holes, Used for the medium of the flow channel plate around and corner hole with rubber (15260, -775.00, -4.83%) gasket to seal the frame by the fixed compression plate, action compression plate, upper and lower guide rod and clamping bolt, etc. Plate heat exchanger is the plate with superimposed situation installed in the fixed compression plate, action compression plate in the middle, and then clamping bolt.

The MSF device with the largest single volume is produced, with a focus of 36000t/d. The titanium plate heat exchanger installed in Italy is a kind of efficient, compact and close heat exchange equipment. It was first developed as a continuous low temperature sterilizer in the 1880s. Since the 1920s, it has been used in the food industry since the titanium plate heat exchanger has some strange features in the creation and application. Therefore, the plate heat exchanger has been widely used in petroleum, chemical industry, light industry, electric power, metal smelting, machinery, energy and other industrial categories. Since the 1960s, plate heat exchangers have been first produced in our country. Until now, plate heat exchangers have been widely used in many fields in our country. Titanium alloy and titanium alloy are a promising metal material emerging recently. Titanium for heat exchange has the advantages of good corrosion resistance, high heat transfer efficiency, smooth appearance, no scale layer, small proportion, high strength, small equipment volume and quality, and is widely used in aviation, space research and development, ocean engineering, petroleum, chemical industry, metal smelting, electronics, medical medicine and health, food processing, spectrograph instrument and other fields.
