PTFE Heat Exchanger Is Very Convenient To Repair Sep 18, 2017

In the process of chemical production, heat exchange and transfer is realized by heat exchanger, and there are often some strong corrosive and strong oxidizing materials in heat exchange, so it is necessary to make heat exchanger with anti-corrosion material, so the PTFE heat exchanger solves this problem well. Here, Rui can give you a brief analysis of the performance characteristics of the PTFE heat exchanger in the anti-corrosion equipment.

PTFE is a chemical inert materials, in addition to the high-temperature elements of fluorine, trichloroethylene and other chemical substances, PTFE Tetrafluoroethane Heat Exchanger almost all of the media can work in the four-fluorine heat exchanger after spraying has very good anti-corrosion performance, its performance characteristics are as follows:

1, due to the chemical inertia of PTFE tube, surface smoothness, winding and high expansion coefficient, so that its heat transfer surface is difficult to scale, PTFE Tetrafluoroethane Heat Exchanger greatly reducing the number of equipment maintenance, to ensure a relatively stable coefficient of heat transfer and production of long-term operation.

2, PTFE heat exchanger Teflon does not contain photosensitive genes, so it has excellent resistance to atmospheric aging. In the strong corrosive medium its service life is 20 to 30 times times of stainless steel, PTFE Tetrafluoroethane Heat Exchanger plus eliminates the maintenance, the accident is caused by the loss, its comprehensive cost is definitely lower than other heat exchangers.

3, four fluorine heat exchanger's heat transfer performance is good, because the heat exchanger uses is the thin-walled tube, therefore overcomes the PTFE material thermal conductivity low disadvantage, PTFE Tetrafluoroethane Heat Exchanger causes its total heat transfer coefficient to reach $number (w/㎡k). The heat transfer technology is used to improve the pressure resistance and the total heat transfer coefficient is improved.

4, PTFE heat exchanger small size, light weight, compact structure, unit volume of heat transfer area is particularly large, in transport, installation, PTFE Tetrafluoroethane Heat Exchanger maintenance is very convenient.

The four fluorine heat exchanger is divided into bundle type and tube shell type; Tube type is the heat exchanger directly installed in the need to heat the solution of the container, to achieve the exchange of heat. Tube-Bundle type heat exchanger installation, maintenance is simple, easy to use; Tube-type heat exchanger has a plate (placed in the Groove side) W-shaped, U-shaped, L-shaped (placed in the trough), PTFE Tetrafluoroethane Heat Exchanger a zigzag or garden-shaped, oval-shaped shape, etc.

PTFE heat exchanger, including the shell, the shell inside the heat row tube, heat exchanger tube at both ends of the fluorine plastic ring, a plurality of heat exchanger tubes are laminated with each other through the fluorine plastic ring at each end of the tube, and the outer surface of the fluorine plastic ring at both ends of the casing and the multi-layer tube is arranged in connection with the column tube, PTFE Tetrafluoroethane Heat Exchanger and the shell is provided with the material inlet and outlet of the cavity in the shell. The shell is provided with a metal pipe wall which is connected with the clamping sleeve to the outer and the outlet of the pipe, PTFE Tetrafluoroethane Heat Exchanger and the plastic anticorrosion layer is compounded by the outside tube. The utility model has the advantages of reasonable structure, high pressure-resisting ability, can withstand -0.1~+1.6MPa working pressure, the heat transfer coefficient can be higher than the ordinary PTFE tube heat exchanger 50%, to 150 kcal/square meters, heat exchanger layout of the proportion of the heat exchanger area, each cubic metre of equipment volume within the heat exchange area of up to 80 square meters , the working temperature reaches -20℃~+200℃.
