How to design and select wide-channel plate heat exchangers?

Thread Content

The wide-channel plate heat exchanger belongs to the type of partitioned heat exchangers; it is a product designed and developed by Beijing Puripler specifically for heat exchange applications involving various solids, crystals, fibers, pasty substances, and high-viscosity media. The plate design features a unique structure with coarse corrugations and wide gap channels; the width of the flow channels between the plates can range from 6 to 16 mm. The outer contour of the plates is composed primarily of horizontal corrugations, and there are no metal contacts between the plates. The medium can flow freely over the heat exchange surfaces of the plates without any blockages or stagnation. This design fills the gap in applications where herringbone corrugations cannot be used, and it offers higher heat transfer performance compared to traditional tubular heat exchangers. When designing and selecting wide-channel plate heat exchangers, it is necessary to understand certain physical properties of the heat exchange medium, such as temperature, flow rate, source of the medium, and whether it contains particles or fibers. Information on the particle size or length of impurities in the medium, as well as whether corrosive substances are present, is also important, in order to ensure a more rational design and selection of the wide-channel heat exchanger. The main models of wide-channel heat exchangers are as follows: Model, Interface Size, Wave Depth (mm), Particle Passage Capability, Pressure Resistance (MPa), Maximum Processing Capacity (m3/h): PLK100DN100 – 4.85; particle diameter that can pass through: 3 mm; pressure resistance: 1180 MPa; maximum processing capacity: 0.6400 m3/h. PLK200DN200 – 6/11.5; particle diameter that can pass through: 6 mm; pressure resistance: 0.6400 MPa; maximum processing capacity: 400 m3/h. PLK250DN250 – 8; particle diameter that can pass through: 5 mm; pressure resistance: 1700 MPa; maximum processing capacity: 1700 m3/h. PLK250LDN250 – 8; particle diameter that can pass through: 5 mm; pressure resistance: 1700 MPa; maximum processing capacity: 1700 m3/h. The available sheet materials include 304/316L/SMO254/Tita/C276; the available gasket materials include NBR/EPDM/Viton. If the particle size in the medium is within 30 mm, or if there are long fibers/stems present, an ultra-wide-channel intelligent heat exchange system can be used for applications such as cold and hot exchange processes in organic fertilizers, livestock farming, slaughterhouses, solid-liquid waste treatment, and biological fermentation. The main design models for ultra-wide channel heat exchange systems are as follows: Model, Interface Size, Maximum Processing Capacity, Material.
