Abstract
The invention relates to an all-welded plate type heat exchanger for multi-stream gas-to-gas heat exchange; an upright quadrangular heat transfer plate assembly module is chosen as a heat transfer element; dust impurities of heat exchange mediums attached on plates fall because of the self weight; moreover, the surfaces of the plates are smooth and have no flowing dead zone, so that the dust-blowing is convenient, the daily maintenance and cleaning of equipment are facilitated and the dust deposition of the equipment is solved thoroughly. The quadrangular heat transfer plate assembly module is a pure counter-flowing corrugated plate; and a hot medium and a cold medium are in a pure counter-flowing state at two sides of the plates. The corrugations of the plates are capable of strengthening heat transfer and play guiding and supporting roles. After the plates are overlapped, a hot medium passage and a cold medium passage are respectively formed at two sides of the plates, and the corrugations contact with one another; the mutual supporting structure is capable of strengthening the medium pressure-bearing ability of the plates; meanwhile, the equipment is compact in structure and small in volume; and the manufacturing cost of the equipment is reduced.
