The invention relates to a housing-and-tube heat exchanging device. The technical scheme is that a plurality of groups of heat exchanging tubes arranged in an inner cavity of a housing; two ends of the heat exchanging tubes are fixed connected through tube plates; a waste water inlet and a softened water outlet are formed in one end of the housing, and a softened water inlet and a waste water outlet are formed in one end of the housing; the softened water outlet, the heat exchanging tubes and the softened water inlet communicate with each other; and the waste water inlet, the inner cavity of the housing and the waste water outlet communicate with each other. The technical problem that it is difficult to completely clean the conventional housing-and-tube heat exchanging devices can be solved; the heat exchanging efficiency of the heat exchanger can be improved; and the service life of the heat exchanger is prolonged. 本发明涉及种壳管换热设备。其技术方案是：壳体的内腔设有多组换热管，换热管的两端通过管板固定连接，壳体的端设有污水入口和软化水出口，另端设有软化水入口和污水出口，所述的软化水出口、换热管和软
