The invention provides a heat exchanger (100, 100', 100'' or 100''') which comprises a housing (110), a baffle (120), a cold material tube (130 or 130''), a hot material tube (140 or 140''), at least a first communication device (160 or 160') and a second communication device (150), wherein the baffle (120) is arranged in the housing and used for dividing the internal space of the housing into upper and lower medium distribution chambers (111 and 112) filled with heat exchange mediums respectively; the cold material tube (130 or 130'') and the hot material tube (140 or 140'') are arranged in the upper medium distribution chamber and the lower medium distribution chamber respectively; cold and hot materials are suitable for being conveyed to pass through the cold and hot material tubes respectively to exchange heat with the heat exchange mediums; the at least a first communication device (160 or 160') and the second communication device (150) are used for communicating the two medium distribution chambers; the heat exchange medium in the upper medium distribution chamber exchanges the heat with the cold material conveyed in the cold material tube to be cooled and enters the lower medium distribution chamber through the second communication device; and the heat exchange medium in the second medium distribution chamber exchanges the heat with the hot material conveyed in the hot material tube to be heated and enters the upper medium distribution chamber through the first communication device. Therefore, all the cold and hot materials flow in a tube pass; and a shell pass is filled with impurity-free clean fluid, so that the problem of high possibility of blockage of impurity fluid in a heat exchange process is effectively solved.

The invention relates to the technical field of printing and dyeing equipment, and discloses a device for recovering waste heat of printing and dyeing equipment, including the printing and dyeing equipment. The device for recovering waste heat from printing and dyeing equipment uses a fan to blow the hot air inside the printing and dyeing equipment into the inside of the fixed block. The air enters in a spiral, which effectively reduces the speed of hot air entering, and the hot air impacts the rotating fan blades. At this time, the rotating fan blades, movable blocks and buffer springs work together to further buffer the effect. The device passes through a series of The unique mechanical structure reduces the flow rate of hot air entering the waste heat recovery device, so that the hot air stays in the waste heat recovery device for a long time, which can fully recover waste heat and make waste heat recovery more efficient. The rotating block fits closely with the guide groove.
