The device comprises a flue formed by an annular water jacket, wherein the lower port of the flue is connected with a furnace body combustion chamber, and the upper port of the flue is connected with a chimney; the flue is internally provided with wave-shaped heat exchange plates which are arranged at intervals and are parallel to the flow direction of flue gas, two adjacent wave-shaped heat exchange plates form a flat box-shaped wave-shaped heat exchange water tank communicated with the annular water jacket, and a flue gas channel is formed between the two wave-shaped heat exchange water tanks. The utility model discloses an application of corrugated plate heat transfer device on clean moulded coal heating stove makes convection heating area can arrange the corrugated heat transfer board as required, need not to increase the volume of heating stove and can optimize structural design, can enough reduce the heating stove cost, can beat and improve heat exchange efficiency greatly again. The problem of traditional clean moulded coal heating stove because heat exchange structure's limitation leads to heat exchange efficiency not high is solved.
Description
Technical Field
The utility model relates to a civilian clean moulded coal heating stove specifically is a heat convection structure of civilian clean moulded coal heating stove.
Background
The heat exchange structure of the existing clean coal heating furnace basically adopts a water jacket and pipe (plate) heat exchange structure, a heat exchange water pipe is horizontally arranged and communicated with the water jacket and is constrained by the volume of a heat exchange cavity, the arrangement of the heat exchange water pipe is limited, the heat exchange area is influenced, and the heat efficiency of the heating furnace is not high.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a heat convection structure of civilian clean moulded coal heating stove, it adopts corrugated plate heat transfer device, improves heat exchange efficiency.
The utility model provides a technical scheme that its technical problem adopted is:
a convection heat exchange structure of a civil clean coal heating furnace comprises a flue formed by an annular water jacket, wherein the lower port of the flue is connected with a furnace body combustion chamber, and the upper port of the flue is connected with a chimney; the flue is internally provided with wave-shaped heat exchange plates which are arranged at intervals and are parallel to the flow direction of flue gas, two adjacent wave-shaped heat exchange plates form a flat box-shaped wave-shaped heat exchange water tank communicated with the annular water jacket, and a flue gas channel is formed between the two wave-shaped heat exchange water tanks.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, beneficial effect is:
through the application of the corrugated plate heat exchange device on the clean coal heating furnace, the corrugated heat exchange plate can be arranged on the convection heating area as required, the structural design can be optimized without increasing the volume of the heating furnace, the cost of the heating furnace can be reduced, and the heat exchange efficiency can be greatly improved. The problem of traditional clean moulded coal heating stove because heat exchange structure's limitation leads to heat exchange efficiency not high is solved.
Further, the utility model discloses an optimization scheme is:
the cross section of the flue is square, and 6 corrugated heat exchange plates are arranged in the flue to form 3 corrugated heat exchange water tanks. Such project organization is more reasonable, can enough effectively improve heat exchange efficiency, also more is favorable to the fume emission to and the combustion effect of clean moulded coal.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a view taken along line A-A of FIG. 1;
in the figure: a furnace body combustion chamber 1; a cigarette folding piece 2; an annular water jacket 3; a chimney interface 4; a flue 5; a corrugated heat exchange plate 6; a wave-shaped heat exchange water tank 7; a flue gas channel 8.
Detailed Description
The invention will be further explained with reference to the following embodiments shown in the drawings.
Referring to fig. 1 and 2, the convection heat exchange structure of the clean household coal heating furnace according to the present embodiment is disposed in a flue 5 formed by an annular water jacket 3. The cross section of the flue 5 is square, the lower port of the flue 5 is connected with the furnace body combustion chamber 1, a smoke folding piece 2 is arranged at the lower port, the upper port of the flue 5 is connected with a chimney interface 4, and high-temperature smoke generated by the furnace body combustion chamber 1 enters the flue 5 through the smoke folding piece 2.
The specific convection heat exchange structure main body is a corrugated heat exchange plate 6, 6 corrugated heat exchange plates 6 are arranged in a flue 5 at intervals in a mode parallel to the flow direction of flue gas, two adjacent corrugated heat exchange plates 6 form a corrugated heat exchange water tank 7 communicated with an annular water jacket 3 and in a flat box shape for one group, the 6 corrugated heat exchange plates 6 form 3 corrugated heat exchange water tanks 7, and a flue gas channel 8 is formed between the two corrugated heat exchange water tanks 7.
The wave-shaped heat exchange plate 6 absorbs the heat of the flue gas to the maximum extent in the heat exchange cavity in the flue 5 and transfers the heat to the water in the wave-shaped heat exchange water tank 7. Two sides of the wave-shaped heat exchange water tank 7 are directly connected with the annular water jacket 3, and compared with the traditional connection mode of the heat exchange tube and the annular water jacket 3, the heat exchange channel accelerates the water flow circulation speed and improves the heat exchange efficiency. The flue gas passes through the flue gas channel 8 and linearly flows from bottom to top, which is beneficial to the discharge of the flue gas and does not influence the combustion effect of the clean coal.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all structural equivalents made by using the contents of the specification and drawings are included in the scope of the present invention.
