What are the advantages and scope of application of Titanium coil heat exchanger?
Titanium coil heat exchanger is a new type of heat exchanger stacked by a series of metal sheets with some corrugated shapes. A thin rectangular channel is formed between each sheet, and heat is exchanged through half a sheet. It is compatible with a conventional shell Compared with the type heat exchanger, its heat transfer coefficient is much higher under the same flow resistance and pump power consumption, and it has a tendency to replace the shell-and-tube heat exchanger within the applicable scale. Titanium plate heat exchangers and plates commonly used in the heat exchanger industry mainly include austenitic stainless steel, titanium and titanium alloys, nickel and nickel alloys, etc. cold-rolled thin industrial pure titanium 127 is used for heat exchangers, and industrial pure titanium 276 And Ti-0.3Mo-0.8Ni345 is used for tube heat exchanger. The heat exchanger made of TA1 titanium plate has many advantages compared with the shell and tube heat exchanger. It has strong competitiveness in the market and is mainly used in chemical industry. , oil, ships, seawater desalination and other heat exchange systems.
It is an ideal liquid-liquid and liquid-vapor heat exchange equipment. It has the characteristics of high heat transfer efficiency, small heat loss, compact and light structure, small footprint, convenient installation and cleaning, wide application and long service life. Under the same pressure loss, the heat transfer coefficient is 3-50% higher than that of the tubular heat exchanger, accounting for one-third of the area of the tubular heat exchanger, and the heat recovery rate can reach 90%.
The removable titanium heat exchanger is made of many punched wave titanium plates sealed with gaskets at some intervals, and overlapped with frames and compression screws. The four corner holes of the plates and gaskets form fluid distribution and collection pipes. At the same time, the cold and hot fluids are reasonably separated so that they flow in the channels on both sides of each titanium plate and exchange heat through the titanium plates.
Titanium coil heat exchanger has the following unique features in design:
(1) Energy saving and high efficiency: its heat transfer coefficient is 3000-4500 kcal/m2?℃?h, which is 3-5 times higher than that of shell-and-tube heat exchangers.
(2) Compact and compact: the plates of the heat exchanger are arranged precisely. Compared with other types of heat exchangers, what are the characteristics of the plate-type pure titanium frame? The area of the titanium plate heat exchanger is 1/5 of that of the shell and tube heat exchanger.
(3) Easy to clean and disassemble: the titanium plate heat exchanger is clamped by clamping bolts, so it is easy to disassemble and assemble, and can be opened and cleaned at any time. At the same time, because the plate surface is smooth and the turbulence is deep, it is not easy to scale .
(4) No liquid leakage, the sealing groove of the titanium plate heat exchanger is provided with a liquid discharge channel, and the various media will not collude. Even if a leak occurs, the medium will always be discharged outward.
(5) The service life is quite long: it is pressed with titanium alloy plates, which can withstand various corrosive media. The rubber pad can be replaced at will, and it can be easily disassembled and repaired.
(6) Good adaptability: The titanium heat exchanger plate is an independent component, which can be increased or decreased according to the requirements, in various forms; it can be applied to the requirements of different processes.
Advantages:
1. The titanium tube heat exchanger is made of industrial titanium precision. The purity of titanium reaches 99.7%. It has strong corrosion resistance, high electrical conductivity, and good heat resistance. It is suitable for processing and cooling low-concentration and acidic liquids; the surface is not easy to produce Oxide layer, no pollution to the medium, no scaling, not easy to block, and protect the environment.
2. The titanium heat exchanger is welded by a special process, and the welding interface is tight and stable, and it is not easy to leak.
3. The titanium tube heat exchanger has a simple structure and high pressure resistance. It adopts an immersion structure and is installed in the container to be heat exchanged. It can be made into a single layer or multiple layers according to the container.
Scope of application:
Titanium heat exchangers have a variety of excellent properties of pure titanium, and are mostly used in a variety of seafood farming, seawater heat exchange, salt water heat exchange, chemical industry, food, metallurgy, refrigeration, light industry, electroplating, aluminum oxide T and other fields. Crude, salt, paper, electronic communications, central heating and other industries and fields.
