Further, in order to make dedusting wiping in use to run up and down smoothly, it is prevented that dedusting is wiped stuck phenomenon occurs in upper and lower running, and the inwall that described through hole contacts with U-shaped heat exchanging pipe is provided with high temperature resistant elastic ring.
Further, described dedusting is wiped as copper dedusting plate.
The beneficial effects of the utility model are: a kind of high temperature flue-gas from boiler residual heat collection tubular heat exchanger that this utility model provides, wiped by the electrical dust-removing being provided with in heat exchanger, elevating lever drives what dedusting wiped to move up and down along U-shaped heat exchanging pipe under the effect of motor, flue dust on the tube wall of U-shaped heat exchanging pipe is struck off, avoid accumulation flue dust on heat exchanging pipe wall, can continue to keep higher heat exchange efficiency, sufficiently conducted waste heat recovery, improve the recovery benefit of residual heat system.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the structural representation of a kind of high temperature flue-gas from boiler residual heat collection tubular heat exchanger of the present utility model.
In figure: U-shaped heat exchanging pipe 1, water inlet 2, outlet 3, air inlet 4, air outlet 5, storage mouth 6, bend pipe 7, on to air-introduced machine 8, air exhauster 9, dedusting wipe 10, motor 11, elevating lever 12.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail. These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the composition relevant with this utility model.
As shown in Figure 1, a kind of high temperature flue-gas from boiler residual heat collection tubular heat exchanger, including: vertically it is provided with heat exchanging pipe in described heat exchanger, described heat exchanging pipe two ends is water inlet 2 and an outlet 3 respectively, described water inlet 2 and outlet 3 are each provided at the top of heat exchanger, the lower end, left side of described heat exchanger is provided with an air inlet 4, and the upper end, right side of described heat exchanger is provided with an air outlet 5, and the bottom of described heat exchanger is provided with a storage mouth 6; Wherein said heat exchanging pipe includes some U-shaped heat exchanging pipes 1, and some U-shaped heat exchanging pipes 1 are connected by some bend pipes 7;
