In the U-shaped heat exchange runner that rounded matrix arrangements are equipped in vivo 2~5 heat exchanger plates of smoke pipe, the heat exchanger plates, the heat exchange
The inlet and outlet of runner is arranged on the side wall of heat exchanger plates, and the inlet and outlet of heat exchange runner is connected with heat exchanger tube, heat exchange stream respectively
The other end for the heat exchanger tube that the inlet and outlet in road is connected with is respectively arranged in a fixed plates and b fixed plates, and is stretched out a respectively and fixed
Outside plate or b fixed plates, the passage that heat exchanger tube is formed with heat exchange runner is formed；Heat exchanger plates are equipped with several smoke ventilators.
The flue gas waste heat recovery apparatus of the present invention, the axial line of the heat exchange runner in the same plane, and smoke-intake pipe
Axis also in the plane.
The flue gas waste heat recovery apparatus of the present invention, the smoke inlet position of the smoke-intake pipe are equipped with flue gas disperser.
The flue gas waste heat recovery apparatus of the present invention, if it is 0.3~0.8mm's that the both ends of the surface of the heat exchanger plates, which are equipped with dry thickness,
Heat absorbing sheet.=
The flue gas waste heat recovery apparatus of the present invention, the outer wall of the water pipe excessively is equipped with thermal insulation material or the outer wall of water pipe excessively is set to true
Empty insulation construction.
The flue gas waste heat recovery apparatus of the present invention, the flow of flue gas direction and the flow direction phase for crossing the water in water pipe
Instead.
The beneficial effects of the invention are as follows:
The heat-exchanger rig of the passage formed by the heat exchanger tube being equipped with heat exchange runner can improve heat exchange efficiency, simplify heat exchange dress
The structure put reduces production cost.
Description of the drawings
Fig. 1 is the structure chart of flue gas waste heat recovery apparatus；
Fig. 2 is the structure chart of heat exchanger plates.
It is marked in figure：1 it is smoke-intake pipe, 2 be smoke exhaust pipe, 3 be water pipe, 4 be heat exchanger components, 5 be heat exchanger plates, 6 is heat exchange
Runner, 7 be smoke pipe body, 8 be heat exchanger tube, 9 be a fixed plates, 10 be b fixed plates, 11 be heat absorbing sheet.
Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
Flue gas waste heat recovery apparatus as shown in Figures 1 and 2, including smoke-intake pipe 1, smoke pipe body 7, smoke exhaust pipe 2 and heat exchanging part
Part 4,7 both sides of smoke pipe body are respectively equipped with into cigarette shop 1 and smoke exhaust pipe 2, and the outer, coaxial of smoke pipe body 7 was arranged with water pipe 3, institute
Stating heat exchanger components 4 includes 2~5 heat exchanger plates 5 being fixed in smoke pipe body 7, and rounded matrix cloth is equipped in the heat exchanger plates 5
The U-shaped heat exchange runner 6 put, the inlet and outlet of the heat exchange runner 6 are arranged on the side wall of heat exchanger plates 5, the import of heat exchange runner 6
And outlet is connected with heat exchanger tube 8 respectively, the other end for the heat exchanger tube 8 that the inlet and outlet of heat exchange runner 6 is connected with is respectively arranged on a and fixes
It on plate 9 and b fixed plates 10, and stretches out respectively outside a fixed plates 9 or b fixed plates 10, forms what heat exchanger tube 8 was formed with heat exchange runner 6
Passage；Heat exchanger plates 5 are equipped with several smoke ventilators, so that flue gas passes through.
In the same plane, and the axis of smoke-intake pipe 1 is also in the plane for the axial line of the heat exchange runner 6.So as to
More heat exchange runners 6 can be equipped on heat exchanger plates 5, to improve heat exchange efficiency.
The smoke inlet position of the smoke-intake pipe 1 is equipped with flue gas disperser, can be by flue gas by the flue gas disperser being equipped with
It is scattered, so as to beneficial to the absorption to flue gas heat.If the both ends of the surface of heat exchanger plates 5 are equipped with the heat absorbing sheet that dry thickness is 0.3~0.8mm
