Abstract

The utility model relates to a hydrogen and oxygen burning range using hydrogen and oxygen generated by a high efficiency water electrolyzing device as fuel and adopting a parallel gas feed combustion system structure composed of a combustion head, an anti-backfire valve, a hydrogen and oxygen pipeline, a hydrogen quantity controlling valve, etc. The utility model has the advantages of no pollution, high speed, convenience and safety, being suitable to be used in modern domestic kitchens.

Description

Hydrogen oxygen burning range

The utility model relates to a kind of combustion oxyhydrogen kitchen range, specifically relates to the home furnace that hydrogen-oxygen that the efficient water electrolysis hydrogen producing oxygen of a kind of usefulness device makes is made combustion heat source.

At present Domestic stove is mainly by the cooking stove of making thermal source with electricity with make the gas stove of fuel with flammable hydrogen body (coal gas, liquid gas oil gas and natural gas etc.).Though easy to use with electric stove, but it is slow to heat up, be not suitable for especially that the traditional culinary art of China requires fry in shallow oil, explode, operation such as quick-fried; And gas stove, although the calorific value height is because the toxicity and the inflammable and explosive property of these gases such as coal gas itself are used safety inadequately, especially for the area in remote deficency source, especially inapplicable.These gas that burns is thrown into carbon dioxide a large amount of in the air and unburnt gas, causes air pollution.Along with the raising day by day of people's quality of life and the quickening of rhythm of life, the kitchen kitchen range are proposed higher standard, need easy to use, safe, quick and free of contamination advanced stove and accessory.

The purpose of this utility model just provides a kind of stove and accessory that fires hydrogen-oxygen, this stove and accessory burns as thermal source to make hydrogen-oxygen from water electrolysis, because oxyhydrogen combustion calorific value height, and oxyhydrogen combustion generates water, realized that recycling, pollution-free, this combustion hydrogen-oxygen stove and accessory of water has overcome the shortcoming of existing electricity and gas furnace, satisfies the requirement of modern kitchen stove and accessory.

The utility model is achieved in that people know that hydrogen or oxygen gas burning back generates water, and is pollution-free, and can produce at least 2000 ℃ thermal-flame during burning, with regard to it does thermal source, is better than gas raw materials such as existing coal gas, liquefied petroleum gas.Often cost is very high but prepare pure hydrogen or oxygen gas, is not suitable for civilian in a large number.The applicant is through concentrating on studies for many years, invented a kind of efficient water electrolysis hydrogen producing oxygen device (patent No. CN1019590B that utilizes high-frequency pulse current, authorize day on December 23rd, 92), this device have volume little, make hydrogen-oxygen purity height, current efficiency can reach more than 80%.Just because of having realized that efficient water electrolysis makes hydrogen-oxygen, makes hydrogen-oxygen become possibility as domestic fuel.The utility model is exactly to utilize the above-mentioned hydrogen-oxygen that is made by water electrolysis hydrogen producing oxygen device as thermal source, and existing stove and accessory is improved, and develops combustion oxyhydrogen kitchen range of the present utility model, has fast, convenient, safety, free of contamination advantage.

Below in conjunction with accompanying drawing (1) (2) (3) combustion hydrogen-oxygen hot water apparatus of the present utility model is described.

Figure (1) is the schematic appearance of combustion oxyhydrogen kitchen range of the present utility model, is two combustion head cooking stoves as shown in the figure, can also be the bull cooking stove.

Figure (2) is the parallel gas feed burning structure schematic diagram of combustion oxyhydrogen kitchen range of the present utility model.

Figure (3) is the combustion head schematic diagram of cooking stove of the present utility model.

Figure (4) is that distribution schematic diagram is chewed in the combustion head surface combustion of cooking stove of the present utility model.

Combustion oxyhydrogen kitchen range of the present utility model is characterised in that and has adopted the parallel gas feed combustion system that this system is by hydrogen inlet (1a) oxygen intake (1b) of hydrogen outlet that is connected to effectively hydrolyzing hydrogen manufacturing oxygen device respectively and oxygen outlet; Hydrogen pipeline (1) that is connected with combustion head (6) and oxygen pipeline (2); An anti backfire valve (3) (4) respectively is set on hydrogen-oxygen pipeline (1) (2); An amounts of hydrogen control valve (5) is installed on the hydrogen pipeline between combustion head and the hydrogen tempering valve, and valve (5) is used to regulate burning velocity.

The combustion head of Fig. 3 is made up of the burner (6c) and the combustion head main body (6d) of the hydrogen passage (6a) that joins respectively with hydrogen-oxygen pipeline (1) and oxygen pipeline (2) and oxygen channel (6b), oxyhydrogen combustion.At the burner place, oxygen enters the inside pipeline of burner, hydrogen enters the outside pipeline that follows around the inside pipeline periphery, the quantity of burner can be provided with several on the stone or metal plate for standing a stove on as a precaution against fire surface according to needs, the right various forms that adopts of its distribution on the stone or metal plate for standing a stove on as a precaution against fire surface, as radial, cellular etc., combustion head of the present utility model can make sufficient combustion and simple in structure.

When using the utility model cooking stove, open hydrogen control valve (5) earlier, connect hydrogen inlet (1a) and oxygen intake (2a) then, igniting, the size of regulating flame by control hydrogen control valve (5).

As seen by above-mentioned, cooking stove of the present utility model has adopted hydrogen-oxygen as combustion heat source, uses the combustion head of parallel gas feed combustion system and new construction, makes that it has had fast, makes things convenient for, clean free of contamination characteristics, is a kind of modern kitchen kitchen range.
