HEAT EXCHANGER AND SMOKE EXHAUSTION PROCESSING DEVICE

To improve workability of maintenance work for a heat-transfer pipe, and suppress stoppage of smoke exhaustion processing work with respect to a heat exchanger and a smoke exhaustion processing device.SOLUTION: A heat exchanger includes: a housing; a plurality of heat-transfer pipes arranged inside the housing; a first header fixed to the housing and connected to one end portions of the plurality of heat-transfer pipes; a second header fixed to the housing and connected to the other end portions of the plurality of heat-transfer pipes; a first access part accessing the connection parts of the plurality of heat-transfer pipes in the first header from the outside of the first header; a second access part accessing the connection parts of the plurality of heat-transfer pipes in the second header from the outside of the second header; a support plate arranged inside the housing and supporting due to insertion of the plurality of heat-transfer pipes into a plurality of support holes; and a resonance prevention plate arranged inside the housing and positioned between the plurality of heat-transfer pipes. The support plate and the resonance prevention plate are arranged so as to cross each other, and divide the inside of the housing into a plurality of space parts.SELECTED DRAWING: Figure 6 【課題】熱交換器および排煙処理装置において、伝熱管のメンテナンス作業の作業性の向上を図ると共に排煙処理作業の停止を抑制する。【解決手段】ハウジングと、ハウジングの内部に配置される複数の伝熱管と、ハウジングに固定されて複数の伝熱管の一端部が連結される第１ヘッダと、ハウジングに固定されて複数の伝熱管の他端部が連結される第２ヘッダと、第１ヘッダの外部から第１ヘッダの内部における複数の伝熱管の連結部にアクセスする第１アクセス部と、第２ヘッダの外部から第２ヘッダの内部における複数の伝熱管の連結部にアクセスする第２アクセス部と、ハウジングの内部に配置されて複数の支持孔に複数の伝熱管が挿通されて支持する支持板と、ハウジングの内部に配置されて複数の伝熱管の間に位置する共鳴防止板と、を備え、支持板と共鳴防止板は、互いに交差するように配置され、ハウジングの内部を複数の空間部に区画する。【選択図】図６
