Detachable plate heat exchanger is a high heat transfer efficiency, compact structure, easy maintenance of heat transfer equipment, has been widely used in heating, air conditioning, water supply and drainage, metallurgy, chemicals, video, petroleum, machinery and other industries, a design staff and the user's choice of plate heat exchanger, BR series plate heat exchanger consists of a pack of corrugated metal plates and gaskets, compression plate, guide bar, column, and took over the clamp bolt and other components. The four corners of the board opened a corner plate heat exchanger consists of a pack of corrugated metal plates and gaskets, compression plate, guide bar, column, and took over the clamp bolt and other components. Angular corners of the board open holes for the two heat transfer fluid passes. Metal plate mounted within the frame fixed plate and movable pressing plate composed, with the clamping bolt intensify. Board equipped with gaskets, seals the fluid passage, and alternately directing the fluid flow into the respective channels. Corrugated board not only improve the level of turbulence, and the formation of a number of support points, enough to withstand the media pressure difference, the performance characteristics of plate heat exchanger, heat transfer efficiency. Corrugated scientific and reasonable size, medium low Reynolds number, it can make the media on the low flow states, the formation of fully turbulent flow, reduce fouling potential, high heat transfer coefficient, K value of up to 3000 ~ 7000W / m2 ℃. Compact, easy washable. In the same mining conditions, only the space occupied by the plate heat exchanger tube heat exchanger Section 1/2 ~ 1/5. Loosen the clamp screw pm washable, removable can within the scope of the original space, without having to set aside a lot of room to repair. Heat transfer area can be increased or decreased. Plate heat exchanger plate as a separate unit, upon request changes in the heat transfer area, process composition flexible, so that changes can be adapted to the requirements. Sheet line long life, operational safety and reliability. When the sheet travel, the use of non-simultaneous clamping of the process to ensure the sheet structure drawing, corrugated precise size, the strength of the sheet-like uniform corrosion resistance of the ministries and organizations. Meanwhile seal pad at the plate intensify state deformation, assembly and maintenance after reinstalling pads reliable sealing, heat transfer medium no internal leakage phenomenon, and the slow progress of the sealing pad aging, long life, safe and reliable operation. Low cost, low investment. Since the plate heat exchanger heat transfer coefficient, heat transfer efficiency in the same conditions, plate heat exchangers and tube heat exchanger only area of ??1 / 2-1 / 4, the cost significantly lower cost. Meanwhile, plate heat exchanger area, cooling water with less evident investment in equipment, power consumption costs are significantly reduced.
