On surface, when needing maintenance, gas distributing rod 13 can be disassembled from the diapire of burner framework 11.
Preferably, distribution member 14 forms the distribution net that shape is consistent, multiple distribution nets the most arranged spaced apart and
Each distribution net is connected with the medial wall of burner framework 11.
In other words, the shape of multiple distribution member 14 keeps consistent, and the most multiple distribution member 14 form equal sized square respectively
Shape distribution net, multiple distribution network arrangements and are spaced layout in premix chamber along the vertical direction, and the periphery of multiple distribution nets is along respectively
Fixing with the medial wall of burner framework 11 and be connected, the most each distribution net can use weldering with the inwall of burner framework 11
Connect, screw connection, the fixed form such as card slot type, specifically can adjust distribution net size, distance, row etc. according to practical situation,
Multiple distribution nets respectively with the wall surface keeping parallelism of catalytic burner 100, beneficially air the most uniformly mixes with combustion gas.
Air and combustion gas mix in respectively enteing premix chamber, and then the gaseous mixture of combustion gas and air sequentially passes through multilamellar
Distribution net, after distribution net distribution, the mixing making the combustion gas of catalytic burner 100 and air is more uniform, divides through multilamellar
Homogeneous mixture after distribution arrives the fire end that of catalytic burner 100 and burns.
Thus, the catalytic burner 100 of embodiment of the present invention gas heater A, cancel the fire row structure in correlation technique,
Use multiple distribution web frame and annular gas distributing rod 13, it is ensured that the combustion gas in each region mixes more uniform with air, real
Existing air premixes with the complete of combustion gas, it is not necessary to secondary air supply, both can simplify the structure of catalytic burner 100, thus subtract
The volume of little catalytic burner 100, it is achieved the lightweight of catalytic burner 100, can improve again the combustion in catalytic burner 100
The efficiency of combustion of gas, reduces the discharge of toxic gas.
Advantageously, burner framework 11 has and the gas outlet of premix chamber conducting, and catalyst converter 12 is located at gas outlet and combustion
The position of the neighbouring gas outlet of burner framework 11 is provided with ignition electrode or inductive needle (not shown).
Specifically, catalyst converter 12 is located at the gas outlet of burner framework 11, and catalyst converter 12 and burner framework 11
Internal face is connected, and such as, catalyst converter 12 can form the structure corresponding with the shape of gas outlet, is then connected to burner framework
On the internal face of 11, thus ensureing that catalyst converter 12 is connected with the fixing of burner framework 11, catalyst converter 12 can form netted, honeybee
Nest shape structure, ignition electrode or inductive needle can sense whether the temperature of catalyst converter 12 exceedes predetermined temperature, when catalytic burner 100
During work, air and combustion gas are sufficiently mixed, so in entering premix chamber by fan interface 11a and combustion gas interface 11b respectively
After catalyst converter 12 at gas outlet preheating, under the effect of catalyst converter 12, combustion gas and air burning catalysis burning,
Burning for catalyst converter 12 provides certain condition, thus reduces the discharge of carbon monoxide and nitrogen oxides, furthermore, catalysis burning
Combustion noise low, safety is higher.
Alternatively, heat exchanger is located at the top of catalytic burner 100, the high temperature that catalytic burner 100 catalysis burning produces
Flue gas carries out heat exchange with the heat exchanger being positioned at above catalytic burner 100, and the cold water in heat exchanger absorbs heat and becomes heat
Water, hot water is flowed out by outlet and uses for user, reduces the waste of energy, and heat utilization ratio is high.
The work process of the gas heater A of the embodiment of the present invention is specifically described below in conjunction with Fig. 1 to 8.
Specifically, as it is shown in figure 1, gas heater A is mainly by housing 200, catalytic burner 100, blower fan 300, combustion gas
Proportioning valve 400 and heat exchanger 500 form.
Wherein, housing 200 vertically (above-below direction as shown in Figure 1) extends, and defines along it long in housing 200
The receiving chamber 21 that degree direction extends, the bottom of housing 200 is provided with into water interface 22 and water outlet mouthpiece 23, accommodates the bottom in chamber 21
Being provided with blower fan 300, catalytic burner 100 is located at the top of blower fan 300 and the fan interface 11a of catalytic burner 100 and blower fan
The outlet of 300, gas ratio valve 400 is located at the side of blower fan 300 and turns on combustion gas interface 11b, and heat exchanger 500 is located at
The top of catalytic burner 100 and being connected with catalytic burner 100, heat exchanger 500 has and the water inlet of water inlet interface 22 conducting
Mouth and the outlet with water outlet mouthpiece 23 conducting.
Blower fan 300 provides air, gas ratio valve 400 to provide combustion gas, the fan interface 11a in burner framework 11 and wind
Machine 300 is connected, and gas ratio valve 400 is connected with combustion gas interface 11b by gas pipeline, and air is connect by blower fan by blower fan 300
Mouth 11a enters in premix chamber, and meanwhile, the combustion gas that combustion gas is limited by fuel gas inlet 13a entrance gas distributing rod 13 by gas pipeline is led to
In road, it is discharged in premix chamber through multiple gas outlet 13b, mixes with air, be covered with many in multiple distribution member 14
Individual dispensing orifice, air is uniform with combustion gas mixing, arrives on the catalyst converter 12 of catalytic burner 100, laggard through ignition electrode igniting
Row burning, high-temperature flue gas and the heat exchanger 500 that burning produces carries out heat exchange, thus the water in heating heat exchanger 500, it is ensured that
Flow out water heater is hot water, and the flue gas after heat exchanges is after exhaust fume collecting hood 600 is collected, by exhaust opening 61 discharge chamber
Outward.
Wherein, the mixture of combustion gas and air combustion process on catalyst converter 12 is: first carry out flaming combustion after igniting,
Catalyst converter 12 is preheated, after the temperature of catalyst converter 12 reaches predetermined temperature, changes combustion gas and the flow of air, make burning
Mode switches to catalysis burning.
Thus, the simple in construction of this gas heater A, compact, each parts connect reliable, and volume is little, and combustion gas and air exist
Carrying out catalysis burning in catalytic burner 100, the carbon monoxide in flue gas and the content of nitrogen oxides after burning are less, energy-conservation
Environmental protection, uses safety, and the mixture combustion of combustion gas and air relaxes, and advantageously reduces the operating noise of gas heater A.
The simple in construction of this gas heater A, compact, each parts connect reliable, are convenient to mount and dismount, and operating noise is low, uses safety, energy-conservation
Environmental protection, Consumer's Experience is good.
