Bypass connecting tube between main header and the main header of water outlet, described bypass are provided with interface in connecting tube, pass through the interface and institute
State the connection of module connecting tube；Bypass connecting tube pipeline section corresponding with each heat exchange module, which is provided with, bypasses on-off valve.When
During a certain heat exchange module leak, the leakage module is cut off, each heat exchange layer is not cut off integrally, does not influence other heat exchange moulds
The normal heat exchange of block, and the unbalanced problem of heat exchange caused by overcoming traditional approach, and the loss of heat exchange area is reduced as far as possible.
Through retrieval, the U of Chinese patent literature CN 201935408 (application number 201020646862.9) disclose a kind of structure
Simply, boiler efficiency can be improved, saves the energy, and can guarantee that a kind of heating boiler of boiler safety reliability service.Present invention bag
The final stage heated calandria of boiler and the header being attached thereto are included, the water inlet and water outlet of its structural feature header are provided with
Valve；Header upper end is provided with vent valve, and the lower end of header is provided with discharging valve.The patent can control opening for whole heating surface
Close, but can not be controlled for single pipe row.
There is heat exchanger structure form disclosed in above-mentioned all kinds of patents document heat exchanger tube to be assembled into set of heat exchange tubes, and arrangement is close
Collection, the characteristics of space availability ratio is high, once but heat exchanger tube corrode, caused leakage the problems such as abrasion, it is necessary to close pipe group,
Wait overhauling after shutting down and recover, it is weaker in the maintenanceability of heat exchanger and operation, present heat exchanger operation can not be fully met
Automation and intelligentification requirement, the reliability of longtime running can not also ensure.
