Abstract
The invention relates to a high-temperature flue gas recoverer with a vent hole. Air in a water circulation system can be exhausted timely through the high-temperature flue gas recoverer, a water circulation is smoother, the contact of a heat pipe and the water circulation is more sufficient and the heat exchange is more complete, and therefore, heat loss can be reduced and energy can be saved. The high-temperature flue gas recoverer comprises a closed flue gas passage and a closed water circulation passage, which are connected with each other through a heat transfer tube; the water circulation passage is provided with a water inlet and a water outlet respectively; the top part of the water circulation passage is provided with a tail end exhaust port; the flue gas passage is provided with a flue gas inlet and a flue gas outlet respectively; a plurality of groups of partition plates are arranged in the water circulation passage; the upper parts of all groups of partition plates are respectively provided with limber holes and vent holes; the limber holes and the vent holes in the partition plates are in staggered arrangement so as to make a water flow circulated in an S-shaped flow direction; the interval between every two of the partition plates is 200-2000 mm; and diameters of the limber holes are 30-200 mm.
Description
One, technical field:
The present invention relates to a kind of coal-burning boiler, coal direct-burning machine, steel-making boiler, stove, dry the equipment that chamber etc. utilizes the high-temperature flue gas waste heat, especially relate to a kind of high temperature flue gas thermal recovery device that is provided with steam vent.
Two, background technology:
In the background technology, a lot of boilers, the coal direct-burning machine, stove, drying chamber etc. does not have high temperature flue gas thermal recovery device, causes thermal loss.And existing flue gas recovery device does not design passage, and the air in the water circulation channel is cumulative, gathers each hydroecium top, and the water surface is formed extruding, causes water circulation not smooth, and adopting heat pipes for heat transfer fails to take full advantage of.
Three, summary of the invention:
The present invention is in order to solve the weak point in the above-mentioned background technology, a kind of high temperature flue gas thermal recovery device that is provided with steam vent is provided, its air in can the in time discharge water circulatory system, make water circulation more smooth and easy, heat pipe contacts more abundant with water circulation, heat exchange is more abundant, thereby can reduce heat loss, energy savings.
For achieving the above object, the technical solution used in the present invention is:
A kind of high temperature flue gas thermal recovery device that is provided with steam vent, it is characterized in that: comprise airtight exhaust gases passes and airtight water circulation channel, exhaust gases passes is connected by heat-transfer pipe with water circulation channel, be respectively arranged with water inlet and delivery port on the water circulation channel, the top of water circulation channel is provided with the tail end venting mouth, is respectively arranged with gas approach and exhanst gas outlet on the exhaust gases passes.
Be provided with many group dividing plates in the above-mentioned water circulation channel, and the top of every group of dividing plate all is respectively arranged with outlet pass and steam vent.
The staggered setting of outlet pass on the aforementioned barriers and steam vent makes current be " S " type and flows to circulation.
Spacing between the aforementioned barriers is the 200-2000 millimeter, and the outlet pass diameter is the 30-200 millimeter.
Above-mentioned water inlet is arranged on the bottom of water circulation channel one end, and delivery port is arranged on the top of the water circulation channel other end.
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
The present invention can in time discharge the air that is trapped in the water circulation system, makes water circulation more smooth and easy, can utilize more fully adopting heat pipes for heat transfer, makes heat exchange more abundant, and then has saved the energy.Solve a FAQs of heat regenerator, used successful through actual.It is simple in structure, and is easy to operate.
Four, description of drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to view;
Fig. 3 is top view of the present invention;
Fig. 4 is the structural representation of median septum of the present invention.
Among the figure, the 1-gas approach; The 2-exhanst gas outlet; The 3-water inlet; The 4-delivery port; The 5-heat-transfer pipe; The 6-hydroecium; The 7-outlet pass; The 8-steam vent; The 9-dividing plate; 10-tail end venting mouth; The 11-exhaust gases passes; The 12-water circulation channel.
Five, the specific embodiment:
Referring to Fig. 1, Fig. 2 and Fig. 3, the present invention includes airtight exhaust gases passes 11 and airtight water circulation channel 12, exhaust gases passes 11 is connected by heat-transfer pipe 5 with water circulation channel 12, be respectively arranged with water inlet 3 and delivery port 4 on the water circulation channel 12, water inlet 3 is arranged on the bottom of water circulation channel 12 1 ends, and delivery port 4 is arranged on the top of water circulation channel 12 other ends.The top of water circulation channel 12 is provided with tail end venting mouth 10, is respectively arranged with gas approach 1 and exhanst gas outlet 2 on the exhaust gases passes 11.Referring to Fig. 3 and Fig. 4, be provided with one group of above dividing plate 9 in the water circulation channel 12, and the top of every group of dividing plate 9 all is respectively arranged with outlet pass 7 and steam vent 8, the outlet pass 7 on the dividing plate 9 and steam vent 8 staggered settings make current be " S " type and flow to circulation.Spacing between the dividing plate 9 is the 200-2000 millimeter, and outlet pass 7 diameters are the 30-200 millimeter.Heat-transfer pipe 5 can be common seamless steel pipe among the present invention, also can be energy-efficient heat transmission steel tube.The medium of water circulation system can be water or other media.
During real work, the high-temperature flue gas that various burners produce enters the exhaust gases passes 11 from gas approach 1, fully contact with heat-transfer pipe 5 in being laid in exhaust gases passes 11, with heat transferred heat-transfer pipe 5, then by exhanst gas outlet 2 discharges of the other end.Heat-transfer pipe 5 in the exhaust gases passes 11 passes to the heat of the high-temperature flue gas that absorbs rapidly and is immersed in the water circulation channel 12 interior other ends.The water inlet 3 of recirculated water from exhaust gases passes 11 enters the water circulation aquaporin 12, forming " S " type by the outlet pass 7 that arranges on the dividing plate 9 between hydroecium 6 flows, fully contact with heat-transfer pipe 5, take away the heat of heat-transfer pipe 5, finally flow out the hot equipment of using that enters from delivery port 4 through the water that heats.The air that is mingled with in the recirculated water is rear finally from 10 discharges of tail end venting mouth by the steam vent 8 that arranges at dividing plate 9.
