Abstract
The utility model relates to a methane burning water heater which is characterized in that the existing gas water heater is improved as follows: the hole diameter of a gas nozzle is changed to be from 1.6 to 1.8 millimeters, the length is changed to be from 16 to 20 millimeters, and two lighting needles of a pulse ignition device are arranged up and down. The lower end of a pole plate which just faces the lighting needles is provided with a gas nozzle, and the hole diameter of a gas outlet of the gas nozzle is from 1.0 to 1.4 millimeters. The upper end of the gas nozzle is provided with a gas guiding tube, the lower end is communicated with a gas valve through a pipeline, and the pole plate above the air guiding tube is provided with a baffle plate. The pole plate above the baffle plate is respectively provided with a point discharging sheet which corresponds to each of the lighting needles. Through the improvement, the utility model can use methane as a gas source to make wide farmers enjoy the benefits which are brought by the gas water heater.
Description
Affiliated technical field
The utility model relates to gas heater, and particularly a kind of combustion biogas water heater is fit to vast rural area and uses.
Background technology
In prior art, gas heater has combustion liquefied gas and two kinds of water heaters of coal gas.The water heater of these two kinds of structures becomes better and approaching perfection day by day, obtains general application in China city.Yet, because biogas production source of the gas height is unstable, the rule of neither one standard, especially fuel value is low, be difficult to use electronic striking, and combustion instability, therefore adopt the structure of existing gas heater can't use biogas.Though there are many producers once to endeavour to solve the problem of unsuitable electronic striking of biogas so that combustion instability, but do not produce the gas heater that can use biogas up to now yet, make vast farmers enjoy water heater as the city dweller, this is a very regret.
Summary of the invention
The purpose of this utility model is can not adopt the deficiency of biogas to make improvements at existing gas heater, and a kind of gas heater that biogas is made fuel of using is provided.
Above-mentioned task realizes by this way: this water heater includes housing, heat exchanger, burner, water valve, air valve, magnetic valve, pulse power generator pulse ignition device, balancer, battery case, water inlet, delivery port and air inlet, it is characterized in that:
1. the aperture of the combustion gas nozzle of burner connection is 1.6～1.8 millimeters, and nozzle length is 16～20 millimeters;
2. two igniting needles towards igniter are arranged above and below together, igniting needle over against the pole plate lower end be provided with an air nozzle, the aperture, gas outlet of this air nozzle is 1.0～1.4 millimeters, establish a wireway in the upper end of air nozzle, its lower end is communicated with air valve by pipeline, pole plate above wireway is established a plate washer, and the pole plate above baffle plate respectively is provided with a point discharging plate corresponding with igniting needle.
Improvement of the present utility model can function as follows:
1. change the aperture of combustion gas nozzle into 1.6～1.8 millimeters from 2.5 millimeters, improved admission pressure, lighting rate is higher, and than the original gas of economizing, the thermal efficiency reaches 80%.In addition, change nozzle length into 16～20 millimeters from original 6 millimeters, make nozzle by through hole to the air inlet of burner, avoid when air inlet, bringing into too much air, be fit to the biogas burning.
2. during routinely structural configuration igniting needle, be the biogas of burner ejection can't be lighted, after above-mentioned improvement, igniting usefulness gas is drawn from air valve specially, spray the baffle plate that hits pole plate from wireway through its nozzle again, make it to produce atomizing, this moment is through two-layer igniting needle continuous impulse sparking, can guarantee that the gas that sprays is lighted, thereby the biogas of the burner on next door ejection is lighted.
After above-mentioned improvement, the utility model can use biogas to make source of the gas fully, has solved the deficiency of prior art, and the big peasant in the side of making enjoys the benefit that water heater brings.
Description of drawings
Fig. 1 is the cross-sectional schematic of a kind of concrete structure of the utility model.
Fig. 2 is the enlarged diagram of pulse ignition device among Fig. 1.
The specific embodiment
With reference to Fig. 1, the structure of housing 1 of the present utility model, heat exchanger 2, burner 3, water valve 4, air valve 5, magnetic valve 6, pulse power generator 7, pulse ignition device 8, balancer 9, battery case 10, water inlet 11, delivery port 12 and air inlet 13 is identical with annexation and existing gas heater basically.The utility model has only been done following improvement: the first changes the aperture of combustion gas nozzle 14 into 1.6 millimeters, and length changes 18 millimeters into, and the air inlet by burner 3 extends in the air admission hole; It two is that two igniting needles 15 with pulse ignition device 8 are arranged side by side up and down in the next door of burner 3, two igniting needles 15 over against the lower end of pole plate 16 be provided with an air nozzle 17, the aperture of this air nozzle 17 is 1.2 millimeters, being provided with a diameter of bore in the top is 2.0 millimeters, length is 20 millimeters wireway 18, directly be 4.5 millimeters in air nozzle 17 lower ends by a root hole, length is that 230 millimeters copper tube pipeline 19 is connected with air valve 5.On the pole plate above the wireway 18 16, be provided with a baffle plate 20, and respectively be provided with a point discharging plate 21 corresponding above it with igniting needle 15.Baffle plate 20 on the pole plate 16 and two point discharging plates 21 can be stamped to form with an iron plate or copper sheet.
