Technical characteristics of plate heat exchanger
Superior Diversion Equipment
The inlet diverter area of the plate is designed with streamline guide grooves, which has the effect of reducing the difference in flow resistance on different flow channels, so that the fluid is evenly distributed in the plate heat exchange area, thereby avoiding uneven flow distribution and flow dead spots. It brings disadvantages such as reduced heat exchange efficiency, pitting and scaling. For plates with larger widths, an equipotential line equalizing groove is also added, so that the resistance formed by the streamline guide groove and the equipotential line equalizing groove is small, and a grid shape with nearly perfect current sharing effect Inlet diversion area. At the same time, the split zone also plays the role of rapid formation of turbulent and strong heat transfer, so that the split zone participates in heat exchange in advance, effectively increasing the length of the heat exchange and reducing the heat exchange area.
Advanced positioning structure
The plate adopts a dovetail-shaped suspension positioning system. The system has three functions:
Suspension: Hang the plate on the upper guide rod, so that it can slide freely forward and backward along the upper guide rod;
Positioning: Make the plate accurate positioning up, down, left and right;
Locking: The newly designed dovetailed hem allows the plates to be automatically locked to each other when clamped, thereby ensuring that all plates can be accurately aligned under any installation conditions, avoiding deviations caused by human factors. The positioning technology of the four corners of the plate is used to make the plates lock and lock each other during assembly.
Special steam-water efficient plate heat exchanger
When the heat source is steam, the traditional shell-and-tube heat exchanger is used. This heat exchanger has a low heat transfer coefficient (1000W / m²-° C), large volume, and difficult to remove scale. Up to 7000W / m²-° C, but because the gasket cannot withstand high temperatures, it is not suitable to use steam directly. To this end, our company has developed a steam-water high-efficiency plate heat exchanger that combines a steam-water direct heat exchanger (desuperheater) and a plate heat exchanger. It takes full advantage of the two types of heat exchangers to achieve operation. Reliable and energy-saving effect.
Introduction of new heat exchange plate
1) The plate corrugation is divided into two sides by the center line of the plate, thereby reducing the difference in resistance between different flow channels and achieving the principle of thermal mixing, which can completely match the heat exchange capacity, flow rate and allowable pressure drop. Greatly save heat exchange area.
2) The heat exchange plate is sealed on both sides. The four corner holes of the plate can be arbitrarily selected according to the actual process.
3) The unique design of the heat exchange plate can be assembled according to different processes and different structural forms. It can be assembled into equal sections and unequal sections, completely breaking the traditional unequal section heat exchanger. The so-called A and B plates combine to form a traditional plate type, with equipment accuracy
