Abstract

The invention provides a plate type air preheater with glasses as heat exchange plates, belonging to the technical field of heat exchangers. The plate type air preheater comprises an air preheater frame, the air preheater frame comprises an upper cover plate (10), a lower bottom plate (11) and a stand column (5) and is internally provided with a plurality of heat exchange plates (1) which are correspondingly placed in vertical direction; a sealing strip (4) is arranged between every two heat exchange plates (1) which are adjacent in vertical direction; the sealing strips (4) are mutually staggered at 90 degrees and form a plurality of sealing fluid channels which are adjacent and mutually staggered at 90 degrees by being placed in a staggered way so as to respectively form hot fluid channels and cold fluid channels; rectangular glass plates are adopted as the heat exchange plates (1), and the glass can be silicon-boron glass and boron-free low-alkali glass or quartz glass; and supporting strips (2) which are rectangular or S-shaped nonmetal plate bars are arranged among the fluid channels formed by the upper and lower heat exchange plates (1). The invention has dew point corrosionresistance, efficiently recovers the low-temperature exhaust heat of smoke and can reduce the temperature of discharged smoke and enhance the efficiency of a heating furnace.

Description

technical field

[0001] The invention belongs to the technical field of heat exchangers, and discloses a plate type air preheater whose heat exchange plates are glass. Background technique

[0002] Heating furnaces and industrial boilers are the main energy-consuming equipment of production equipment in the electric power and petrochemical industries, and their energy consumption accounts for about 50-70% of the total energy consumption of the equipment. In today's increasingly scarce energy, it is undoubtedly particularly urgent to improve the efficiency of heating furnaces. One of the main measures to improve the thermal efficiency of boilers and industrial furnaces is to reduce the exhaust gas temperature and recover the waste heat in the flue gas. Reducing the exhaust gas temperature and recovering the waste heat in the flue gas are the most important technical measures to improve the efficiency of heating furnaces and industrial furnaces. However, so far, the biggest ob...
