In the past, the recovery and utilization of the medium in the production line of large particles mostly used tubular heat exchanger, but the tubular heat exchanger was characterized by large volume, poor heat transfer effect and poor corrosion resistance.A plate-type heat exchanger is mainly composed of a metal plate and a sealing gasket. The plate has four corner holes for the passage of hot and cold media.A network channel is formed between the plates, and the sealing gasket seals the hot and cold media in the heat exchanger, and reasonably separates the hot and cold media at the same time.

The groove depth on the surface of the plate is the key to whether the medium with large particles can pass smoothly, while the technical difficulty of "groove depth" is not easy to break through. Whether the raw materials of the plate are thick enough and the uniformity of the stretch of the plate is linked to the technical strength of the company.The unique shape of corrugated plate of 6-12 mm not every company can do, metal can form a layer of passivation film in the air, the smaller the degree of stretch, break the extent is smaller, the better the corrosion resistance, but for special condition, need to pull sheets - 12 mm to 10 mm, this 2 mm is actually present technical strength, board piece break down problems directly affect the degree of corrosion resistant plate.

Combined in order to improve thermal efficiency in GEA, and the advantage of the heat exchanger, Qingdao rui put r&d engineer team with 20 years of industry experience in technology research and development on continuous improvement and application of a wide flow plate heat exchangers instead of the original tube heat exchanger, the heat exchanger advantage is small size, in high thermal efficiency, simple installation steps, anticorrosive is good, service life can reach more than 10 years.
