Abstract
A fuel gas water heater with a waste heat recycling device comprises a housing, a waste heat recycling device, a heat exchanger, a smoke discharging tube and a fan, wherein the heat exchanger comprises a combustion chamber and a heat exchanging water guide tube which is arranged on the combustion chamber; one end of the heat exchanging water guide tube is a water inlet end; the other end of the heat exchanging water guide tube is a hot water outlet end; the fan is arranged at the top of the combustion chamber; the fuel gas water heater is characterized in that the waste heat recycling device comprises a heat exchanging water tank and a gas guide tube which is mounted in the heat exchanging water tank; one end of the gas guide tube is connected with a gas exhaust opening of the fan; the other end of the gas guide tube is connected with the smoke discharging tube at the top of the housing; a water inlet and a preheated water outlet are formed in the heat exchanging water tank; the water inlet is communicated with a water source; and the preheated water outlet is communicated with the water inlet end of the heat exchanging water guide tube. As the structure is adopted, the smoke gas with afterheat, which is exhausted from the combustion chamber, enters the waste heat recycling device, the heat is transmitted to the water in the heat exchanging water tank by the gas guide tube and the smoke gas is exhausted after being cooled. Therefore, the afterheat is sufficiently utilized and the heat efficiency is increased.
Description
Technical field
The utility model relates to various gas heaters.
Background technology
Present existing gas heater, generally comprise shell, overheavy firing chamber, combustion chamber assembly, water tank, smoke exhaust pipe and blower fan etc., during forced-ventilated gas water heater work, directly enter in atmosphere by smoke exhaust pipe the high-temperature flue gas that the combustion chamber produces by blower fan, not only can cause the water heater thermal efficiency to reduce, also waste large quantity of exhaust gas heat energy.For this situation, the utility model technology has been carried out structure optimization to the deficiency of above existence, so that gas heater reaches the purpose of energy-saving and emission-reduction.
Summary of the invention
The purpose of this utility model is: a kind of gas heater with waste heat recovery plant is provided, and it can effectively utilize the fume afterheat that discharge the combustion chamber, has improved the thermal efficiency.
The utility model is achieved in that a kind of gas heater with waste heat recovery plant, comprise shell, waste heat recovery plant, heat exchanger, smoke exhaust pipe and blower fan, described heat exchanger comprises combustion chamber and the heat exchange aqueduct that is arranged on the combustion chamber, and heat exchange aqueduct one end is that water inlet end, the other end are hot water effluent's end; Described blower fan is arranged on the top of combustion chamber; Its special character is: described waste heat recovery plant comprises heat-exchanging water tank and is installed on the interior wireway of heat-exchanging water tank, wireway one end connecting fan exhaust outlet, the smoke exhaust pipe at other end connected with outer casing top; Heat-exchanging water tank is provided with water inlet and preheating water delivery port, and water inlet is communicated with the water source, and the preheating water delivery port is communicated with the water inlet end of heat exchange aqueduct.
Described a kind of gas heater with waste heat recovery plant, its special character is: the wireway of described waste heat recovery plant has one at least, and wireway in the shape of a spiral.
Described a kind of gas heater with waste heat recovery plant, its special character is: the bottom of described heat-exchanging water tank is provided with blow-off pipe.
Described a kind of gas heater with waste heat recovery plant, its special character is: described water source is communicated with the water inlet at heat-exchanging water tank top, and heat-exchanging water tank bottom delivery port is communicated with the water inlet end of heat exchange aqueduct.
A kind of gas heater with waste heat recovery plant of the utility model is owing to adopt such structure, the flue gas that the band that discharge the combustion chamber has surplus heat, enter waste heat recovery plant, wireway is discharged the water in the heat transferred heat-exchanging water tank after the cooling, take full advantage of waste heat, improve the thermal efficiency.

Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of gas heater with waste heat recovery plant, comprise shell, waste heat recovery plant, heat exchanger 1, smoke exhaust pipe 2 and blower fan 3, described heat exchanger 1 comprises combustion chamber 11 and the heat exchange aqueduct that is arranged on the combustion chamber 11, and heat exchange aqueduct one end is that water inlet end 121, the other end hold 122 for the hot water effluent; Described blower fan 3 is arranged on the top of combustion chamber 11; Described waste heat recovery plant comprises heat-exchanging water tank 4 and the wireway 5 that is installed in the heat-exchanging water tank 4, wireway 5 one end connecting fans 3 exhaust outlets, the smoke exhaust pipe 2 at other end connected with outer casing top; Heat-exchanging water tank 4 is provided with water inlet and preheating water delivery port, and water inlet is communicated with water source tube 6, and the preheating water delivery port is communicated with the water inlet end 121 of heat exchange aqueduct.
The wireway 5 of described waste heat recovery plant has one at least, and wireway 5 in the shape of a spiral.
The bottom of described heat-exchanging water tank 4 is provided with blow-off pipe 7.
Described water source tube 6 is communicated with the water inlet at heat-exchanging water tank 4 tops, and heat-exchanging water tank 4 bottom delivery ports are communicated with the water inlet end 121 of heat exchange aqueduct.
Described cold water inlet 6 is communicated with the water inlet at heat-exchanging water tank 4 tops, and the delivery port of heat-exchanging water tank 4 bottoms is communicated with the water inlet end 121 of heat exchange aqueduct.Adopt this spline structure, cold water from top to bottom flows, and waste gas residual heat from lower to upper motion in wireway 5, cold water and wireway mutually carry out heat and transmit exchange, thereby greatly improve the thermal efficiency, save a large amount of gas consumptions.
Above-described only is preferential embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art in the situation that does not break away from the utility model principle, can also make some improvement and modification, this also is considered as protection domain of the present utility model.
