1. Technology Name

Dalian Dongfang Yipeng-Wound Heat Exchanger Technology

Wound Heat Exchanger(Coil-Wound Heat Exchanger) has incomparable advantages compared to ordinary shell-and-tube heat exchangers.It belongs to the shell-and-tube heat exchanger of the wall heat transfer principle.It has a wide applicable temperature range, can adapt to thermal shock, self-eliminate thermal stress, and has high compactness. Due to its special structure, the flow field is fully developed, with no flow dead zones, especially by setting multiple tube passes.(single pass in the shell), it can meet the simultaneous heat exchange of multiple fluid streams within one device..

The wound heat exchanger is formed by alternately winding heat transfer tubes in a spiral shape in the space between the core tube and the outer tube, with adjacent layers of spiral heat transfer tubes having opposite spiral directions, and using certain shaped spacers to maintain a certain distance, as shown in the figure.:

This heat exchanger is widely used in hydrogenation cracking, reforming, low-temperature methanol washing, gas storage facilities, and other devices..

2. Advanced Features

Compared with ordinary shell-and-tube heat exchangers, the wound heat exchanger has the following characteristics:

1) Compact structure, with a large heat exchange area per unit volume.

2) Good thermal compensation capability, the thermal expansion of the heat exchange tubes can be partially self-compensated.3) By selecting a certain number of winding layers and reasonably distributing the flow areas of the tube and shell sides, pressure drop is reduced.

34) Interleaved spiral winding, good turbulence effect, excellent heat transfer enhancement effect, and high heat transfer efficiency, achieving a low-end temperature difference of 2°C.It can simultaneously conduct heat transfer for multiple media.

44) Interleaved spiral winding, good turbulence effect, excellent heat transfer enhancement effect, and high heat transfer efficiency, achieving a low-end temperature difference of 2°C.High pressure and large scale.3. Case Sharing

  64) Interleaved spiral winding, good turbulence effect, excellent heat transfer enhancement effect, and high heat transfer efficiency, achieving a low-end temperature difference of 2°C.This multi-stream wound heat exchanger is a national key project.

—— The largest gas storage facility in Northeast China, the Shuangtaizi Gas Storage of PetroChina Liaohe Oilfield, is one of the core devices.

Currently, this heat exchanger is the heaviest, largest diameter, longest winding, and largest heat exchange area wound tube heat exchanger in domestic gas storage projects.

It has created multiple firsts in similar domestic natural gas processing devices.Technical parameters:The design pressure of this equipment is 14MPa, design temperature -20°C to 50°C, heat exchange area 6159㎡, diameter 3200mm, length about 16000mm, total weight about 270 tons.Photos of loading at Dongfang Yipeng factory.Photos of successful operation on site.CCTV News "Morning News" and Finance "Economic Information Broadcast" extensively reported on the completion and production of the largest gas storage facility in Northeast China.

—— The Shuangtaizi Gas Storage Group of PetroChina Liaohe Oilfield.

This gas storage facility is responsible for the seasonal peak shaving task of natural gas in Northeast and Beijing-Tianjin-Hebei regions, which has significant social and strategic significance for enhancing the winter natural gas supply capacity in Northeast and Beijing-Tianjin-Hebei regions, adjusting China's energy structure, promoting energy conservation and emission reduction, addressing climate change, ensuring gas supply safety, and national strategic reserves.CCTV Media News Report.
