Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
As shown in fig. 1, the utility model provides a hot-blast furnace chimney heat recovery utilizes device, this hot-blast furnace chimney heat recovery utilizes device include feeder hopper 1, feed bin 2, blower housing 3, annular duct 4, guide duct 5, heat-transfer pipe 6 and air-blower 7. Feeder hopper 1 is connected with hot-blast furnace 8's feed inlet, 2 tops that erect on hot-blast furnace 8's lateral wall of feed bin and be located feeder hopper 2, feed bin 2 is big-end-up's toper form, and the upper and lower both ends opening of feed bin 2, fuel conveyor transports the back to fuel, throw in fuel from the upper end of feed bin 2 earlier and keep in feed bin 2, fuel drops feeder hopper 1 from the lower extreme of feed bin 2 again, burn in the furnace of leading-in hot-blast furnace 8 of fuel by feeder hopper 1 at last. Optionally, the lower end of the bin 2 is provided with a discharge switch so as to control the amount of fuel temporarily stored in the bin 2.
