The technical solution of the utility model is:
The dismountable boiler smoke-gas residual-heat recovering device of a kind of heat exchanger tube, comprise storage tank, described storage tank one side is provided with the smoke inlet being connected with described boiler outlet flue, opposite side is provided with exhanst gas outlet, on described smoke inlet, be fixedly installed the first tube sheet, on described exhanst gas outlet, be provided with the second tube sheet, on described first, second tube sheet, be provided with the through hole of the corresponding setting of array, between the through hole of described every group of corresponding setting, be all connected with heat exchanger tube, described every heat exchanger tube removably connects with corresponding through hole on first, second tube sheet.
Further, described every heat exchanger tube adopts and is threaded with corresponding through hole on first, second tube sheet.
Further, described every heat exchanger tube adopts fastening nuts to connect with corresponding enlightening hole on first, second tube sheet.
Further, described every heat exchanger tube adopts and is threaded with corresponding through hole on the first tube sheet, adopts fastening nuts to connect with corresponding through hole on the second tube sheet.
Further, at least distance setting of about 6cm of interval between through hole on described the first tube sheet, the through hole on described the second tube sheet and the corresponding setting of through hole on the first tube sheet.
Compared with prior art, the beneficial effects of the utility model are as follows:
In the utility model, heat exchanger tube adopts detachable installation, is easy to change.The dismountable boiler smoke-gas residual-heat recovering device of heat exchanger tube that the utility model provides, comprise storage tank, its storage tank one side is provided with the smoke inlet being connected with boiler outlet flue, opposite side is provided with exhanst gas outlet, on its smoke inlet, be fixedly installed the first tube sheet, on exhanst gas outlet, be provided with the second tube sheet, first, on the second tube sheet, be provided with the through hole of the corresponding setting of array, between the through hole of its every group of corresponding setting, be all connected with heat exchanger tube, every heat exchanger tube with corresponding first, through hole on the second tube sheet removably connects, this mode removably connecting can be for every heat exchanger tube with corresponding first, through hole on the second tube sheet adopts screw threads for fastening to connect or fastening nuts connects, also can heat exchanger tube adopt and be threaded with through hole on corresponding the first tube sheet, with corresponding through hole fastening nuts connection on the second tube sheet etc., thereby when heat exchanger tube occurs aging, during damage, can selectively change, and do not need heat exchanger tube to carry out integral replacing, thereby reduced the operating cost of device, reduced economic loss.
