Abstract

The utility model provides a novel liquid fuel quick-acting carburetor which has a carburetor body. A liquid inlet pipe and a gas outlet pipe are arranged on the carburetor body, the upper part of the inner cavity of the carburetor body is a gas storage chamber, and the lower part is a liquid storage chamber. The utility model is characterized in that a quick-acting preheating chamber is formed by that a sandwich layer is arranged in the inner cavity of the carburetor body, and the upper and the lower parts of the quick-acting preheating chamber are respectively communicated with the gas storage chamber and the liquid storage chamber. The utility model has the advantages that the preheating time is shortened, the liquid fuel of weak volatility can also be fully vaporized in short time, no pressure needs to be additionally applied, the operation is safe, and the structure is simple. The liquid fuel quick-acting carburetor is an ideal up-to-date product for the coal users.

Description

Liquid fuel quick-acting carbureter

The utility model relates to use fluid combustion device technique field, is particularly suitable for the vaporization of synthetic liquid fuel.

Along with continuous progress in science and technology and living standards of the people improve gradually, it is to adopt liquid fuel that fuel-device both domestic and external has more,---coal and gaseous fuel---is as the major advantage of natural gas, coal gas etc. because liquid fuel not only has solid fuel, and solved the main scarce latent of solid and gaseous fuel, thereby liquid fuel is subjected to people's favor.For the various burners that use liquid fuel, the ignition procedures of liquid fuel and vaporization degree have extremely close the contact, promptly must make this atomization of liquid carefully also and air effectively and equably mix and just can make it be easy to light.At present, the vaporization of liquid fuel mainly is divided three classes: the first kind is a pressure-type, it is to rely on the liquid fuel steel cylinder of band pressure or inflate the pressure that is produced by artificial pressurization and realize liquid fuel evaporation, because the air spouting velocity is low, mist of oil is of poor quality, it is insufficient to burn, and power consumption is high, and the steel cylinder of band pressure has many unfavorable factors such as dangerous, inconvenient, expense height.Second class is a volatile-type, it is to utilize the extremely strong special liquid fuel of volatility to vaporize naturally to realize, need not pressurize and inflate though utilized the natural physical characteristic of this class I liquid I fuel, but its unsafe factor is more, and require the sealing property height of burner or storage fuel tank, and increase the fuel production cost.The 3rd class is the preheating vaporization type, it is to put small amount of liquid fuel earlier to ignite in preheater, liquid fuel heat in the gasifier is made its vaporization, the more preceding two class advanced persons of its performance, but owing to be that vaporizer and liquid integral body are heated, so required preheating time is longer, could normally use after about 2 minutes, extremely inconvenient.In order to accelerate to light the process of using the fluid combustion device and to use the general more weak liquid fuel of volatility, therefore, the utmost point is necessary existing vaporizer is improved.

The purpose of this utility model provides the quick vaporizer of improved liquid fuel and solves above-mentioned problems of the prior art, enters normal use so that use the more weak fluid combustion device of general volatility also can light fast.

The purpose of this utility model is achieved through the following technical solutions.

The quick vaporizer of liquid fuel described in the utility model, one carburetor body is arranged, on carburetor body, be provided with feed tube and escape pipe, carburetor body inner chamber top is air receiver, the bottom is a liquid-accumulating chamber, it is characterized in that being provided with an interlayer and form the rapidly pre-warming chamber in the carburetor body inner chamber, the upper and lower part of rapidly pre-warming chamber is communicated with air receiver, liquid-accumulating chamber respectively.

The quick vaporizer of liquid fuel described in the utility model design preferably is, interlayer is by the thermostable heat insulation material or scribble heat insulating coat in the metal surface and make.

The better design of the quick vaporizer of liquid fuel described in the utility model is: carburetor body is a tubular, and its top is bell mouth shape, in the bottom of carburetor body preheater is installed, and at the horn mouth place of carburetor body burner is installed.

Adopt the burner of the quick vaporizer manufacturing of liquid fuel described in the utility model to have the following advantages: (1) is owing to designed the rapidly pre-warming chamber in vaporizer, shortened preheating time greatly, the ignition procedures of burner is exceedingly fast, and reaches normal use even adopt the more weak liquid fuel of volatile performance also can fully vaporize in the short period of time.(2) light owing to it only needs that small amount of liquid fuel is put into preheater, make the indoor liquid fuel heat vaporization of rapidly pre-warming, just can finish the preheating vaporescence.Therefore, can use various liquid fuels, be particularly suitable for the vaporization of cheap alcohol synthetic liquid fuel.(3) simple in structure, manufacturing cost is low, does not need impressed pressure, and is safe and reliable.(4) it is coal-fired user's a desirable regeneration product, compare it with natural gas class gas combustion apparatus and do not need pipe laying, be convenient to move to different local uses, its investment is 1/3rd of an oil liquefied gas, it is the sixth of natural gas investment, liquid fuel is easy to buy on market, does not have the sorrow of stopping the supple of gas or steam.

With reference to the accompanying drawings the quick vaporizer of this liquid fuel is described in further detail.

Fig. 2: the quick vaporizer schematic top plan view of liquid fuel

Fig. 3: the burning apparatus for combustion of liquid fuel that the quick vaporizer of liquid fuel has been installed cuts open the operation principle schematic diagram after showing.

Fig. 1～2nd, the specific embodiment of the quick vaporizer of liquid fuel, it has carburetor body 1, carburetor body 1 the most handy stainless steel material is made tubular, its top is bell mouth shape, on carburetor body, be provided with feed tube 2 and escape pipe 3, the rapidly pre-warming chamber 7 that the carburetor body inner chamber can be divided into top air receiver 4 and bottom liquid-accumulating chamber 5 and be formed by the interlayer 6 that is arranged in the carburetor body inner chamber, the top of rapidly pre-warming chamber is communicated with air receiver, burn so that be discharged in the burner by escape pipe 3 behind the liquid fuel evaporation, the bottom of rapidly pre-warming chamber is communicated with liquid-accumulating chamber, interlayer 6 can be selected general metal material for use, scribble heat insulating coat or adopt the thermostable heat insulation material to make but be preferably in the metal performance, help the vaporization of rapidly pre-warming indoor liquid fuel like this.Fig. 3 is that burning apparatus for combustion of liquid fuel that the quick vaporizer of this liquid fuel has been installed cuts open the operation principle schematic diagram after showing, its course of work is as follows; Proportional valve 9 provides quantitative liquid fuel for automatically the preheater 10 that is installed in the carburetor body bottom in opening controlling valve 8, and light liquid fuel in the preheater 10 by ignition 11, the heat that burning produces is passed to rapidly pre-warming chamber 7 vaporizes liquid fuel wherein fast, the gaseous fuel that produces is transported to air nozzle 12 ejections by escape pipe 3 through control valve 8 to be mixed with air, arrive burner 14 beginning normal combustion through current divider 13 again, the part heat that burner produces makes liquid fuel continuation vaporization in the quick vaporizer, thereby guaranteed that gaseous fuel constantly offers burner combustion in a steady stream, main liquid reserve tank 15 is communicated with the feed tube 2 of the quick vaporizer of liquid fuel.
