Description

The heat-exchange device of gas heating stove

Technical field

The utility model relates to a kind of warming installation, specifically a kind of heat-exchange device of gas heating stove.

Background technology

Traditional coal heating stove is big because of its flue dust, lime-ash is more, environmental pollution is more serious, and progressively substituted by other heating installation, wherein, gas heating stove is a kind of heating mode preferably, gas heating stove is with its clean hygiene, pollution-free, advantages such as handled easily generally are subjected to the consumer and welcome, and particularly in China urban area, source of the gas is abundant, as coal gas, liquefied gas or natural gas, and be widely used.Heat-exchange device in the present gas heating stove, most structure is a directly burning type, the flame of combustion gas heats body or the wall body that recirculated water is housed from bottom to top, discharges from the air outlet on heat-exchange device top then.The Proper Design thermal conversion rate of this warming stove is low, can not make full use of the heat energy of burning, and a large amount of heat energy have scattered and disappeared along air outlet, and heat-energy losses is big, utilization rate is low, wastes energy.

Summary of the invention

The purpose of this utility model provides a kind of thermal conversion rate height, can make full use of the heat energy of fuel gas buring, the heat-exchange device of the gas heating stove that heating effect is good.

The technical solution adopted in the utility model is: a kind of heat-exchange device of gas heating stove, comprise the housing, the pipeline that have water-in and water-out interruption-forming water jacket, be provided with the combustion chamber in the described housing, the top of combustion chamber is communicated with the exchange pipe, the layout of exchange pipe in housing, back and forth circling round, the other end of exchange pipe stretches out and is connected with air exhauster in that end of water inlet of housing, and delivery port is arranged on that relative with water inlet on housing end.

Described housing is vertical, and water inlet is arranged on lower housing portion, and delivery port is arranged on the top of housing, and described exchange pipe is a helix tube, is surrounded on the outside of combustion chamber from top to bottom.

Described exchange pipe is to manage in a zigzag, and back and forth circling round from top to bottom is arranged at a side of combustion chamber.

Described housing is a horizontal type, and described exchange pipe is by a side direction opposite side of the housing layout of back and forth circling round.

The back and forth place of circling round of inherent each the exchange pipe of housing is provided with shelf, and the recirculated water in the housing is trickled to delivery port along the trend of exchange pipe from water inlet.

Described exchange pipe is many and is arranged side by side.

Because the utility model is provided with the exchange pipe with the top of combustion chamber, the exchange pipe is reciprocal room structure, can prolong the stroke of flame heat radiation, can make the water in the housing fully absorb heat energy, improves thermal conversion rate; Exchange pipe hot-fluid of the present utility model trend is opposite with water (flow) direction in the housing, the heat energy of the utilization burning of maximal efficiency, increase thermal conversion efficiency; The exchange pipe is connected with air exhauster, makes heat energy unimpeded at combustion chamber best friend's replace tubes stroke.

The specific embodiment

Fig. 1 is the structural representation of a kind of embodiment 1 of this practicality, comprise housing 1, combustion chamber 2 and exchange pipe 3 etc., the housing 1 of present embodiment is vertical, this housing 1 has the water jacket of water inlet 4 and delivery port 5 for sidewall, be equipped with in the housing 1 and can supply hydronic water, water inlet 4 is arranged on the bottom of housing 1 usually, is connected with water inlet pipe, delivery port 5 is arranged on the top of housing 1, is connected with outlet pipe and water pump.Combustion chamber 2 is arranged on housing 1 inside, be the inside of water jacket, the top that the space of combustion chamber 2 extends to housing 1 is communicated with exchange pipe 3, this exchange pipe 3 is reciprocal room structure from top to bottom, the exchange pipe 3 of present embodiment is a helix, be wound in the outside of combustion chamber 2 from top to bottom, stretch out from the bottom of housing 1 lower end of exchange pipe 3, is connected with discharge duct by air exhauster.

2 bottom rises to top through the combustion chamber for the flame of the utility model combustion gas 2 internal combustion in the combustion chamber and heat, enter then in the exchange pipe 3, because exchange pipe 3 bottoms are provided with air exhauster, so the heat of combustion chamber 2 is along exchange pipe 3 walking from top to bottom, heat is progressively absorbed by the water in the housing 1, water is heated, and realizes hot conversion, and the flue gas in the exchange pipe 3 enters the discharge duct discharge by air exhauster at last.Because the exchange pipe 3 that is provided with combustion chamber 2 and back and forth circles round in the water jacket that housing 1 forms has prolonged the stroke of flame heat radiation, has increased the endotherm area in the water jacket, thermal conversion efficiency height, energy savings.The shape of the utility model exchange pipe 3 can also be that back and forth circling round from top to bottom is arranged at a side of combustion chamber 2 in a zigzag except the helix in the foregoing description.

Fig. 2 is the schematic diagram of the utility model embodiment 2, comprise housing 1, combustion chamber 2 and exchange pipe 3 etc., described housing 1 is a horizontal type, and combustion chamber 2 is arranged on the side in the housing 1, delivery port 5 is arranged on that side of close combustion chamber 2 on the housing 1, and water inlet 4 is arranged on that side away from combustion chamber 2.The top of combustion chamber 2 is communicated with exchange pipe 3, and described exchange pipe 3 is layouts of back and forth circling round of the side direction opposite side by housing 1, and exchange is managed 3 housings 1 from close water inlet 4 those sides and stretched out with air exhauster and be connected.In the housing 1, be provided with shelf 6, the recirculated water in the housing 1 is trickled to delivery port 5 along the trend of exchange pipe 3 from water inlet 4 at the recess that back and forth circles round of each exchange pipe 3.

Exchange pipe 3 of the present utility model can also be many and be arranged side by side, and all is communicated with combustion chamber 2.

The flow direction of the heat energy of the utility model burning in exchange pipe 3 be with housing 1 in the flow direction of recirculated water opposite, like this, combustion gas is in discharge process, higher in exchange pipe 3 upper end temperature, be subjected to the temperature of hot water also higher, during to exchange pipe 3 lower ends, the hot air temperature of process heat exchange significantly descends, and therefore is subjected to the temperature of hot water also lower; In like manner, when the recirculated water that is used to warm oneself was back to switch, temperature was lower, and at first contact is the hot gas of the lower temperature of exchange pipe 3 lower ends, progressively flows to the high-temperature region on top then, and water temperature progressively rises.So design, the heat energy that utilizes combustion gas that can maximal efficiency, thermal conversion efficiency height.The utility model is provided with water pump at delivery port 5 places can make the more effective circulation of heating water, improves radiating efficiency.

The utlity model has rational in infrastructurely, the thermal conversion rate height can fully absorb heat energy, heating effect The characteristics such as good.
