Description

Domestic stove and range for synthetic fuel

The present invention relates to a kind of civil kitchen range, be applicable to that methyl alcohol does family's cooking of fuel, also can be used as the civil kitchen range of liquefied synthetic fuels such as ethanol, diesel oil emulsification.

The methyl alcohol genus prior art that acts as a fuel.Well-known methyl alcohol is a kind of toxic organic compound, when its when nature is burnt, overflow because of its incomplete combustion can make poisonous gas, health is worked the mischief.For being introduced family's cooking as novel synthetic fuel, methyl alcohol avoids again human body is formed murder by poisoning, existing technology such as practicality novel " Carbinol stove " (application number 88211632.0, notification number CN2032688U) way of Cai Yonging is to make methyl alcohol be burning again behind the gas through pre-thermocatalytic, decomposition gasification earlier, and its principle is shown in following equation:

CH ₃OH (catalyst)/(heating) CO+2H ₂

The weak point of this prior art, the one, can realize that under the situation of catalysis material and heating primary electron lights a fire successfully, otherwise use just inconvenient, the 2nd, though methyl alcohol is through pre-thermocatalytic, still difficulty reaches and decomposes vaporization fully, therefore its thermal efficiency is only below 60%, and because of vaporization combustion is incomplete, and some pernicious gases of may overflowing; The 3rd, the same with other liquid fuel cooking range.Easily tie carbon and stop up at its shower nozzle place, so result of use is not very good.

The utility model is on the architecture basics of normal domestic use gas kitchen ranges and liquid fuel cooking range, by reform to combustion chamber, nozzle, by-pass valve control etc., its objective is provide a kind of energy directly, safety, high efficiency utilizes liquefied synthetic fuels such as methyl alcohol, can solve hydrops that general liquid fuel cooking range is connected with, knot carbon simultaneously again and just can not electronic ignition successfully wait the novel household kitchen range of disadvantage without giving heat.

The utility model is realized in the following manner:

1。In fuel tank, pack into methyl alcohol or other liquefied synthetic fuel, and be pressed into the 0.05-0.3MPa air, form pressure reservoir.Adopt triple valve control at basin and fuel inlet pipe junction, its effect is under rated operating pressure (0.05-0.3MPa), and control gas, liquid liquid are supplied with and closed.

2。Nozzle is made bell mouth shape, and bore its objective is to make through triple valve that the fuel that fuel-supply pipe enters stove diffuses into atomized spray to the combustion chamber between 6-16mm.

3。Therefore easily formation knot carbon and obstruction in nozzle of burning owing to liquefied synthetic fuel be provided with a cleansing pin in nozzle, cleansing pin bar and electronic lighter join, and reverse cleansing pin like this in sparking, cleansing pin is played drill through, eliminate the effect of tying carbon.

4。Make cylindrical netted double-deck combustion chamber and be fixed on combustion chamber central authorities with metal material, inside and outside combustion chamber diameter is respectively φ 56-65mm and φ 28-36mm, and centre-to-centre spacing 2-5mm is drilled with fine and closely woven mesh on the combustion chamber, and the aperture is φ 0.5-2mm.The effect of combustion chamber has three, one, can play the effect of " chimney " in combustion process, makes cold air rotate into the combustion chamber, reaches the effect of abundant oxygen supply; The 2nd, under fired state, combustion chamber is heated, fuel contact combustion chamber and the rotation therein injected by nozzle distribute and motion, actual is the process of a preheating, and can be decomposed into littler vaporific of particle through the fine and closely woven mesh of combustion chamber through the liquid fuel of the preliminary atomizing of nozzle, add pre-heat effect, fuel can fully gasify and be decomposed into fine and closely woven vaporific fuel gas, but therefore primary electron igniting success and reach higher efficiency of combustion; The 3rd, the capillarity of combustion chamber mesh can make a small amount of hydrops that produces in the combustion chamber participate in burning fully under siphonage.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is novel synthetic fuel civil kitchen range schematic diagram

Fig. 2 is novel synthetic fuel civil kitchen range combustion chamber schematic diagram

Fig. 3 is novel synthetic fuel civil kitchen range nozzle and cleansing pin structural representation

Fig. 4 is novel synthetic fuel civil kitchen range triple valve schematic diagram

With reference to Fig. 1, it is shared that the stove 1 of kitchen range, electronic lighter 2, nozzle 3, combustion chamber 4, burning cover 5, fuel tube 6 and fuel tank 7 are general household gas utensils, and primary structure of the present utility model is characterized as:

1。Referring to Fig. 2, combustion chamber 8 is set in the combustion chamber 4, it two-layerly is made of inside and outside, makes cylindrically with metal material, diameter is φ 56-65mm and φ 28-36mm, evenly stamps mesh 9 on the combustion chamber, pore size is φ 0.5-2mm, between the mesh apart from 2-5mm.

2。With reference to Fig. 3, bell mouth shape is made in nozzle 3 outlets, and bore is φ 6-16mm, dress cleansing pin 12 in nozzle, and cleansing pin bar and electronic lighter join.

3。With reference to Fig. 4, fuel tank 7 exits are provided with triple valve 10, and this valve is by valve rod 11 controls, in a, b, c three ports, the a mouth also is that stove 1 communicates with fuel tube 6, and the b mouth extends the fuel tank bottom and joins with methyl alcohol or other liquid, and the c mouth then is positioned at the air place, top of fuel tank, when valve rod 11 is all opened, under rated operating pressure 0.05-0.3MPa effect, b, c two implication liquid mix derivation, close the c mouth, then b mouth liquid is derived, and stops using and then closes two mouthfuls of b, c.

Compared with the prior art, the utlity model has following advantage:

1. When methyl alcohol or other liquid are made fuel, can be without preheating with a knob electronic striking success, easy and simple to handle, as using coal gas and liquefied petroleum gas.

2. Because the special multiple action of combustion chamber, can make the liquid fuel decomposition of fully gasifying, reach the evenly heat efficient more than 70%, be higher than national standard more than (55%) 15%.

3. Because gasifying, burning fully, the effusion of pernicious gas can be curbed few state equally, after testing, the room air situation is methyl alcohol＜1mg/m during burning³, formaldehyde＜0.04mg/m³，SO ₂＜0.015mg／m ³，NO＜0.072mg／m ³，CO＜0.140mg／m ³, all be lower than state-set standard, nontoxic pollution-free.

4. Because having increased needle-valve, solved nozzle and tied the problem of carbon, obstruction, simultaneously because the generation of hydrops in the combustion chamber is also avoided and eliminated to capillary, the siphonage of combustion chamber.
