Description
Technical field
The utility model relates to a kind of condensation structure of gas heater, particularly a kind of condensation structure of strong drum type gas heater.
Background technology
Condensed type combustion gas water heater owing to its thermal efficiency than the high favor that receives users of common water heater, its exhaust gas temperature is low than common water heater again, meets the demand of national energy-saving and emission-reduction policy.Have corrosive condensed water but condensed type combustion gas water heater in use can produce, the collection discharging that how to solve condensed water has become problem demanding prompt solution.In the existing condensation technology, the flow direction and the flow of flue gas of condensed water are in the opposite direction mostly, and making the heat exchanger fin easy blocking of secondary heat exchange device had both influenced the heat exchange effect, are unfavorable for the discharging of flue gas again.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, and providing a kind of can address the above problem, and the secondary heat exchange device can not stop up, good effect of heat exchange, and smoke evacuation is the condensation structure of strong drum type gas heater smoothly.
The utility model is realized through following technical scheme: a kind of condensation structure of strong drum type gas heater; Comprise enclosure, first heat exchanger and secondary heat exchange device; It is characterized in that also comprising smoke guiding cover and condensed water collection box; Top and sealing that wherein said smoke guiding cover is installed on the secondary heat exchange device cooperate, and smoke guiding cover is positioned at enclosure, and the side of smoke guiding cover is trapezoidal shape and parallel with the medial surface of enclosure; Said first heat exchanger is installed in the lower end that condensed water is collected box; Said enclosure is installed in the upper end that condensed water is collected box, and said secondary heat exchange device is installed in condensed water and collects in the box, and the bottom surface of collecting box at said condensed water is provided with discharge outlet; On condensed water collection box, be provided with exhaust gases passes; The bottom surface that said exhaust gases passes and condensed water are collected box isolates, and an end of exhaust gases passes communicates with first heat exchanger, and the other end communicates with smoke guiding cover.
The edge that described condensed water is collected between the box and first heat exchanger is provided with the silica gel sealing pad that seals, and two exhaust gases passes are located at the forward and backward both sides that condensed water is received packaging case respectively.
The bottom surface that said condensed water is collected box is skewed, and said discharge outlet is positioned at the low side that condensed water is collected the bottom surface of box.
The lower end undulate of the fin of described secondary heat exchange device and end plate.
The edge that said enclosure and condensed water are collected between the box is provided with the silica gel sealing pad that seals.
The utility model advantage compared with prior art is: owing to adopt the smoke guiding cover of top closure; Condensed water is collected the bottom surface sealing and the exhaust gases passes of box, makes that the flow direction of flue gas in condensed water is collected box is consistent with the flow direction of condensed water, and the heat exchanger fin of secondary heat exchange device is difficult for blocked; Help the discharging of flue gas; Improve the heat exchange effect and the smoke discharging effect of gas heater greatly, can reduce the fin gap simultaneously, dwindled the volume of secondary heat exchange device.Because the position of the discharge outlet of condensed water collection box tool is in than low side, helps condensed water and discharge again.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.
Extremely shown in Figure 5 like Fig. 1; A kind of condensation structure of strong drum type gas heater; Comprise enclosure 1, first heat exchanger 7 and secondary heat exchange device 4, the utility model characteristics are also to comprise smoke guiding cover 2 and condensed water collection box 5, and top and sealing that wherein said smoke guiding cover 2 is installed on the secondary heat exchange device 4 cooperate; Smoke guiding cover 2 is positioned at enclosure 1, and the side of smoke guiding cover 2 is trapezoidal shape and parallel with the medial surface of enclosure 1; Said first heat exchanger 7 is installed in the lower end that condensed water is collected box 5; Said enclosure 1 is installed in the upper end that condensed water is collected box 5, and said secondary heat exchange device 4 is installed in condensed water and collects in the box 5, and the bottom surface of collecting box 5 at said condensed water is provided with discharge outlet 52; On condensed water collection box 5, be provided with exhaust gases passes 51; Said exhaust gases passes 51 is isolated with the bottom surface that condensed water is collected box 5, and an end of exhaust gases passes 51 communicates with first heat exchanger 7, and the other end communicates with smoke guiding cover 2.
In the present embodiment, the edge between the described condensed water collection box 5 and first heat exchanger 7 is provided with silica gel sealing pad 6, two exhaust gases passes 51 that seal and is located at the forward and backward both sides that condensed water is received packaging case 5 respectively.
In the present embodiment, the bottom surface that said condensed water is collected box 5 is skewed, and said discharge outlet 52 is positioned at the low side that condensed water is collected the bottom surface of box 5, is convenient to discharge condensed water like this and collects the water in the box 5.
In the present embodiment, enough flow channels are arranged, the lower end undulate of the fin of described secondary heat exchange device 4 and end plate 41 in order to ensure flue gas.
In the present embodiment, the edge between said enclosure 1 and the condensed water collection box 5 is provided with the silica gel sealing pad 3 that seals.
During work, flue gas upwards flows after 7 heat exchange of first heat exchanger, after arriving at condensed water and collecting the bottom of box 5; Because after the 5 bottom surfaces sealing of condensed water collection box, flue gas through the 51 continuation risings of forward and backward side two exhaust gases passes, are arrived at smoke guiding cover 2; Because the top closure of smoke guiding cover 2, flue gas flows downward, behind secondary heat exchange device 4 secondary heat exchanges of flowing through; The condensed water that produce this moment is because the gravity effect also flows downward, and flue gas is consistent with the mobile direction of condensed water, and the heat exchanger fin of secondary heat exchange device 4 is difficult for blocked; Also help simultaneously the discharging of flue gas, improved the heat exchange effect and the smoke discharging effect of gas heater greatly.After condensed water arrived at the bottom of condensed water collection box 5, because condensed water is collected the gradient that the bottom of box 5 has certain discharge outlet of being partial to condensed water 52, condensed water was from can discharge from discharge outlet 52 smoothly.The flow through passage of smoke guiding cover 2 lateral surfaces and the formation of enclosure 1 medial surface of last flue gas, the exhaust opening through enclosure 1 top enters in the atmosphere.
