Abstract

The utility model relates to a domestic fuel oil water heater, comprising a heat exchanger in which a gas flue is arranged, and a burner whose middle parts of the inner housing and the outer housing are provided with oil cores with high-temperature fiber material. The air is taken in the tangential direction to make one part of the fuel oil on the oil cores vaporized rapidly by the high temperature in a burning chamber and the other part flushed by the tangential air flows to form atomized liquid drops for vaporization to burn completely in the burning chamber. After entering the heat exchanger, the generated high temperature smoke gas is discharged from the gas flue, and simultaneously, a temperature sensor is arranged on a water outlet pipe to control a temperature linkage valve to regulate the oil feeding mass to control the burning intensity, making the water leaving temperature constant. The utility model has the advantages of simple structure, low cost, easy use and safety.

Description

Domestic fuel-oil water heater

The utility model includes the water heater of heat generator.

Water heater is a lot of in the market, and gas heater, electric heater etc. are arranged.Although the former its safety guard is very perfect, automaticity is also very high, and security is worrying all the time; The latter causes electric leakage, electric shock phenomenon because of malfunctioning switch, and is also very dangerous.And both structures are all complicated, and reasons such as cost height also do not have a large amount of huge numbers of families that enter.

The purpose of this utility model provides the tangential air intake of a kind of employing, makes fuel oil at the washing away of tangential air stream formation mist attitude drop and produce the fuel-oil water heater of violent burning down, can overcome problems of the prior art.

The technical solution of the utility model is made up of heat exchanger component, combustor component, air blast, oil tank etc.Heat exchanger component: the heat exchanger of flue is arranged in comprising, outlet pipe is arranged on the heat exchanger, water inlet pipe is arranged at the bottom; Combustor component: comprise inside and outside shell, the banking fire circle at inner casing top, wick is equipped with at inside and outside shell middle part, the oil-in of wick one end is communicated with oil tank, the other end is with the anti-high temperature fiber that has, the air inlet of shell is communicated with air blast, and air can be from air inlet space through between inside and outside housing, and the tangential small through hole of inner shell bottom enters the combustion chamber.The high-temperature flue gas that burner produces is discharged by flue after entering heat exchanger, and the cold water heating is discharged by outlet pipe.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1. structural representation of the present utility model;

Fig. 2. burner structure schematic diagram of the present utility model;

Fig. 3. smoke filter structure principle chart of the present utility model.

As shown in Figure 1 and Figure 2, the heat exchanger 5 that flue 4 is arranged in heat exchanger component comprises, temperature inductor 3, outlet valve 1 are housed on the outlet pipe 2 on heat exchanger 5 tops, temperature inductor 3 is connected with temperature interstage valve 13 on the oil inlet pipe 8 by temperature signal line 15, and heat exchanger 5 bottoms are passed through water inlet pipe 17 and are connected with water intaking valve 16.Burner 10 parts comprise shell 19, inner casing 20, banking fire circle 21 is arranged at inner casing 20 tops, interior, wick 23 is equipped with at the shell middle part, one end oil-in 26 of wick 23 is through temperature interstage valve 13, fuel tap 18, fuel pipe 8 is communicated with oil tank 6, liquid level gauge 7 is housed on the oil tank 6, the other end of wick 23 is with high-temperature fibre 22, the air inlet 24 of shell 19 is through air valve, blast pipe 11 is communicated with air blast 12, air can be in air inlet 24 warps, space between shell body, uniform tangential small through hole 27 enters the combustion chamber on the inner casing 20 bottom circumference, and whole burner 10 usefulness nuts 25 are fixed on the shell 19.For reduce polluting, smoke filter 9 parts are set, as shown in Figure 3, it comprises filter seat 28, in the catch net 29 of high-temperature fibre 30 is housed, and compress with trim ring 31.

Operation principle is to drive fuel tap 18 earlier, the liquid level difference that fuel oil is produced by heat exchanger 5 top oil tanks 6 and supplying with continuously, as fuel oil when wick 23 overflows, by igniter 14, after introducing is caught fire wick 23 from inside and outside shell aperture, drive air blast 12, finish ignition process.When normal combustion, fuel oil part on the wick is rapid carburation by evaporation owing to the high temperature in the combustion chamber, mix mixing of formation gas phase and violent burning with air, another part fuel oil leaves wick and forms vaporific drop under the washing away of tangential air stream, the rapid vaporization combustion in the space, bigger as liquid-drop diameter, under the rotary air action of centrifugal force, be thrown to the inner casing wall of high temperature and rapid vaporization combustion.Because air is tangentially to enter the combustion chamber, therefore gas mixture rotates in the combustion chamber, make wick top form the recirculating zone on the one hand, stablized burning, prolonged the time of staying of gas mixture in the combustion chamber on the other hand widely, also promoted oil to mix with the heating power of air, make burning complete, stable, burning indoor temperature height, carbon deposit not, imperfect combustion gas content is few in the flue gas.

When igniting, a small amount of carbon black is arranged in the flue gas, pollute for reducing heat exchanger, the spy is provided with smoke filter 9, and carbon black smoke is sucked by smoke filter, and when normal combustion, because filter temperature is high, the carbon black that produces during igniting is by burning out, and filter is purified.The high-temperature gas passes filter 9 that burner produces enters heat exchanger 5, discharges through flue 4, and cold water enters heat exchanger from water inlet pipe 17, and discharges hot water by outlet pipe, and water yield is regulated by outlet valve 1.Because when water yield changes, will cause water temperature to change, water yield causes leaving water temperature to descend greatly, otherwise coolant-temperature gage rises, and obtains temperature signal by temperature inductor 3 for this reason, and control temperature interstage valve 13 is regulated to oil mass, control burning is strong and weak, makes effluent temperature constancy.Or the size of adopt regulating water intaking valve and fuel tap, make effluent temperature constancy.

The utility model compared with prior art its advantage is: because employing is with the wick of refractory fibrous material, burner adopts tangential air inlet structure, with match direct-fire or use ignition device, so efficiency of combustion height, smoke dust, simultaneously at outlet pipe the temperature sense device is set and controls the temperature linkage valve and regulate to oil mass, the control combustion power is so that effluent temperature constancy. This water heater, simple in structure, cost is low, and is easy to use, safe and reliable, and popularizing value is arranged very much.
