Provided are a nonmetal corrosion-resistant heat exchange device (20) and a plate-type heat exchanger (100) having same. The heat exchange device (20) comprises a plurality of nonmetal corrosion-resistant heat exchange sheets (21), upper support ribs (22) and lower support ribs (23) installed on top and bottom surfaces of each heat exchange sheet (21), sealing strips (25) disposed at the upper and lower edges at each side of the heat exchange sheets (21), and spacers (26). The adjacent upper support ribs (22) and the lower support ribs (23) located between the adjacent heat exchange sheets (21) together define multiple sealing channels for cold fluid and hot fluid. The spacers (26) completely seal the upper support ribs (22), the lower support ribs (23) and the sealing strips (25) via a press force.
