Abstract
The utility model is an exhaust device of gas water heater comprising a smoke exhaust pipe (1), a smoke exhaust pipe joint (2) and a smoke collecting cover (3); wherein, one end of the smoke exhaust pipe (1) is put in one end of the smoke exhaust pipe joint (2), and the other end of the smoke exhaust pipe joint (2) is put in one end of the smoke collecting cover (3). The outer diameter of the smoke exhaust pipe (1) is the same with the inner diameter of the smoke exhaust pipe joint (2). As the utility model adopts the structure that one end of the smoke exhaust pipe is put in one end of the smoke exhaust pipe joint and the other end of the smoke exhaust pipe joint is put in one end of the smoke collecting cover, when smoke flows through the smoke exhaust pipe, the produced condensate can only flow into the inside of the smoke collecting cover from inner wall without the possibility of flowing to the outside of the smoke collecting cover, so as to avoid the corrosion damage of other components. The utility model is an exhaust device of gas water heater which is simple in structure, convenient and practical.
Description
1, technical field:
The utility model is a kind of fume extractor that is used for gas heater, and especially a kind of external fume extractor of condensing type water heater belongs to the innovative technology of the used fume extractor of gas heater.
2, background technology:
The flue-gas temperature of existing general gas water heater higher (more than 110 ℃), the steam in the flue gas are difficult to form condensed water in the smoke evacuation process.And the exhaust gas temperature of condensed type combustion gas water heater has only about 60 ℃, easily produces condensed water during by smoke pipe.The NOx in the flue gas (nitrogen oxide) and the condensed water synthetic acidic aqueous solution.This class acidic aqueous solution oozes out the stainless steel smoke pipe, and other part of water heater and surrounding environment are caused damage.The connected mode of outer smoke collecting tube of water heater commonly used and water heater smoke exhaust pipe joint adopts jacket-type, for the ease of installing and changing, has selected bigger fit-up gap, so that condensed water oozes out from their cooperation slit easily.
3, summary of the invention:
The purpose of this utility model is to consider the problems referred to above and a kind of condensed water seepage that can not only prevent is provided, and the fume extractor that is used for gas heater easy for installation.The utility model is simple in structure, and is convenient and practical.
Structural representation of the present utility model as shown in Figure 1, include smoke exhaust pipe (1), smoke exhaust pipe joint (2), exhaust fume collecting hood (3), wherein an end of smoke exhaust pipe (1) is inserted in an end of smoke exhaust pipe joint (2), and the other end of smoke exhaust pipe joint (2) is inserted in an end of exhaust fume collecting hood (3).
The outside dimension of above-mentioned smoke exhaust pipe (1) is identical with the internal diameter size of smoke exhaust pipe joint (2).
The utility model is owing to adopt an end of smoke exhaust pipe to be inserted in an end of smoke exhaust pipe joint, and the other end of smoke exhaust pipe joint is inserted in the structure of an end of exhaust fume collecting hood.Therefore, when flue gas was flowed through smoke exhaust pipe, the condensed water that is produced can only be flowed into the inside of exhaust fume collecting hood by inwall, and can not flow to the outside of exhaust fume collecting hood, thereby avoided other parts to be subjected to corrosion and damage.The utility model is a kind of simple in structure, the convenient and practical fume extractor that is used for gas heater.
4, description of drawings:
Fig. 1 is a structural representation of the present utility model.
5, the specific embodiment:
Embodiment:
Structural representation of the present utility model includes smoke exhaust pipe 1, smoke exhaust pipe joint 2, exhaust fume collecting hood 3 as shown in Figure 1, and wherein an end of smoke exhaust pipe 1 is inserted in an end of smoke exhaust pipe joint 2, and the other end of smoke exhaust pipe joint 2 is inserted in an end of exhaust fume collecting hood 3.The interface position that is about to smoke exhaust pipe is designed to reducing, and the interface position of smoke exhaust pipe joint is designed to enlarging, makes condensate return in the smoke exhaust pipe to water heater inside.
In the present embodiment, the outside dimension of above-mentioned smoke exhaust pipe 1 is identical with the internal diameter size of smoke exhaust pipe joint 2.
The utility model is contained on the water heater and uses, and when flue gas was flowed through smoke exhaust pipe 1, the condensed water that is produced can only be flowed into the inside of exhaust fume collecting hood by inwall, and the outside that can not flow to exhaust fume collecting hood causes other parts to be subjected to corrosion and damage.
Claims (2)
1, a kind of fume extractor that is used for gas heater, include smoke exhaust pipe (1), smoke exhaust pipe joint (2), exhaust fume collecting hood (3), it is characterized in that an end of smoke exhaust pipe (1) is inserted in an end of smoke exhaust pipe joint (2), the other end of smoke exhaust pipe joint (2) is inserted in an end of exhaust fume collecting hood (3).
2, the fume extractor that is used for gas heater according to claim 1 is characterized in that the outside dimension of above-mentioned smoke exhaust pipe (1) is identical with the internal diameter size of smoke exhaust pipe joint (2).
