Detailed description of the invention

Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, the most ad initio Represent same or similar element to same or similar label eventually or there is the element of same or like function.Below by ginseng It is exemplary for examining the embodiment that accompanying drawing describes, it is intended to be used for explaining this utility model, and it is not intended that to this utility model Restriction.

Below with reference to the accompanying drawings gas heater 1 according to this utility model embodiment is described.

As it is shown in figure 1, include heat exchanger 100, flameless burner according to the gas heater 1 of this utility model embodiment 200, premix cavity 300 and heat storage water tank 400.

Heat exchanger 100 has heat exchange water inlet 110 and heat exchange outlet 120.Flameless burner 200 is for heat exchanger 100 heat, and are provided with catalyst carrier in flameless burner 200, and described catalyst carrier is provided with catalyst.Premix cavity 300 for carrying the mixed gas of air and combustion gas to flameless burner 200, and premix cavity 300 is with flameless burner 200 even Logical.Heat storage water tank 400 has heat insulation function, and heat storage water tank 400 has water tank inlet 410 and water outlet of water tank 420, and water tank enters The mouth of a river 410 connects with heat exchange outlet 120.

The work process of the gas heater 1 according to this utility model embodiment is described below with reference to Fig. 1.

After combustion gas and air enter premix cavity 300, after being sufficiently mixed in premix cavity 300, it is delivered to nonflame combustion Burner 200.Mixed combustion gas and the air described catalyst in described catalyst carrier, described catalyst carrier promotees Making mixed combustion gas and air carry out catalysis burning, the heat that flameless burner 200 burning simultaneously produces and burning produce The heat of high-temperature flue gas is transferred to heat exchanger 100.Water at water source enters heat exchanger 100 by heat exchange water inlet 110, is heated Heat exchanger 100 transfers heat to the water in heat exchanger 100 to heat water, and the water after heating passes through heat exchange outlet 120 and water tank inlet 410 enter heat storage water tank 400 in be incubated, discharged by water outlet of water tank 420 when user's water For user.

Gas heater 1 according to this utility model embodiment, by arranging premix cavity 300, can make entrance combustion gas The air of water heater 1 and combustion gas enter back into flameless burner 200 after mixing in premix cavity 300.So can make sky Gas and combustion gas enter back into flameless burner 200 and participate in burning after being sufficiently mixed, be possible not only to improve the efficiency of combustion of combustion gas, And fuel gas buring can be made more abundant, it is to avoid the generation of harmful gas.

Further, by arranging the described catalyst carrier with described catalyst in flameless burner 200, it is possible to use Described catalyst promotes air and combustion gas that catalysis burning occurs, and heats realizing heat exchanger 100.Burning due to combustion gas It is catalyzed by described catalyst, fuel gas buring can be made more abundant, be possible not only to improve the utilization rate to combustion gas, improve The efficiency of combustion of combustion gas, and the harmful gas produced due to burn incompletely when can reduce burning, reduce further and have The generation of evil gas.

Further, owing to flameless burner 200 can make combustion gas carry out flameless combustion, can be so that controlling flameless combustion Ignition temperature in device 200, compares the mode of direct combustion gas in correlation technique, can avoid due to burner temperature too high and Cause the generation of harmful gas, the harmful gas produced during further fuel gas buring, and also flameless combustion is compared with directly burning, The noise produced is lower, improves comfort level when user uses further.

Additionally, by arranging heat storage water tank 400, it is possible to use heat storage water tank 400 stores the water after heating, and carries out water Insulation.When user's water, flow through the water after heat exchanger 100 heating and be introduced into heat storage water tank 400 and storage in heat storage water tank 400 Water mix after, then by water outlet of water tank 420 discharge for user.So can reduce due to hydraulic pressure instability etc. The factor impact on output water temperature, makes output water temperature more constant, improves comfort level during user's water.

Therefore, have according to the gas heater 1 of this utility model embodiment be not likely to produce harmful gas, use comfortable etc. Advantage.

Below with reference to the accompanying drawings gas heater 1 according to this utility model specific embodiment is described.

In specific embodiments more of the present utility model, as it is shown in figure 1, according to the combustion gas heat of this utility model embodiment Hydrophone 1 includes heat exchanger 100, flameless burner 200, premix cavity 300 and heat storage water tank 400.

Described catalyst carrier is provided with multiple gas via.Specifically, it is provided with described catalysis in described gas via Agent.Combustion gas and air so can be enable to enter described gas via, improve the contact surface of combustion gas and described catalyst carrier Long-pending, thus make combustion gas fully burn further.

Alternatively, described catalyst carrier is ceramic honey comb or steel part.Described catalyst carrier so can be made to have Good thermostability and structural strength.

Specifically, described catalyst carrier is cordierite-quality honeycombed ceramics.Described catalyst carrier so can be made to have Good thermostability, and the cost of described catalyst carrier can be reduced so that the manufacture of described catalyst carrier.

Wherein, described catalyst is to be coated in the noble metal in described catalyst carrier or nonmetal.The most all can be real The now catalytic action to combustion gas, makes combustion gas carry out catalysis burning.

Advantageously, described catalyst is mixed by platinum, palladium and rhodium.So can improve described catalyst combustion gas is urged Change effect, enable combustion gas fully to burn, it is to avoid the generation of harmful gas.

Further, in described catalyst, the quality of platinum accounts for the 10%-15% of described catalyst quality, in described catalyst The quality of palladium accounts for the 50%-75% of described catalyst quality, and in described catalyst, the quality of rhodium accounts for described catalyst quality 20%-30%.So can improve the described catalyst catalytic effect to combustion gas further, enable combustion gas fully to burn, keep away Exempt from the generation of harmful gas.

Fig. 1 shows the gas heater 1 according to one concrete example of this utility model.As it is shown in figure 1, premix cavity 300 connect the blower fan 320 having for carrying air in premix cavity 300 and for the combustion premixing cavity 300 delivery of fuel gas Gas proportioning valve 310.So it is possible not only to be easy to utilize blower fan 320 and gas ratio valve 310 to carry air in premix cavity 300 And combustion gas, and the adjustment to fuel gas transmission amount can be realized by adjusting gas ratio valve 310, real by adjusting blower fan 320 The now adjustment to air conveying capacity, on the one hand can be so that regulating the combustion efficiency of flameless burner 200, in order to adjusting water outlet Temperature, on the other hand can be conveniently adjusted the ratio of combustion gas and air, enable combustion gas fully burn further, reduces harmful gas The generation of body.

Advantageously, as it is shown in figure 1, gas heater 1 also includes controller 500, controller 500 respectively with blower fan 320 and Gas ratio valve 310 communication.Controller 500 so can be utilized to control blower fan 320 and gas ratio valve 310, in order to combustion The conveying capacity of gas and air is adjusted.

Specifically, as it is shown in figure 1, gas heater 1 also includes for collecting and discharge the cigarette that flameless burner 200 produces The exhaust fume collecting hood 600 of gas.Specifically, the flue gas that flameless burner 200 burning produces can enter exhaust fume collecting hood through heat exchanger 100 In 600.So can be so that the flue gas producing flameless burner 200 burning be collected and discharges, to prevent fume emission Indoor to user, it is ensured that the safety of gas heater 1.
