The utility model discloses a plate type heat exchanger for gas-gas heat exchange, comprising a shell, a plurality of single tubes, a heat gas inlet, a heat gas outlet, a cold gas inlet and a cold gasoutlet, and a plurality of the single tubes are arranged in the shell; the plate type heat exchanger is characterized in that: the single tubes are welded into a plate type tubular structure by two steel plates with symmetrical structures, vertical grooves are distributed on the steel plate at interval, and the side all of the single tube is designed into transverse corrugated rib structure fromtop to bottom, whirling pipes are arranged among the tubes, and the steel plate adopts 1-1.5mm of stainless steel plate. Compared with the traditional heat exchanger, the heat transfer coefficient isimproved by 30-40 percent and can reach 30-35w/Km<2>; under the same condition, the resistance can be reduced by about 20 percent compared with the resistance of the whirling sheet screen sharp-expansion accelerated flow hollow circular-tube shell type heat exchanger; the heat exchanger can change heat for gas with no more than 800 DEG C and can exchange heat to acid fog gas containing concentrated sulfuric acid and phosphoric acid; the heat exchanger has the characteristics of low manufacturing cost and long service life.
