Abstract

The utility model relates to a range for liquefied petroleum gas, which is especially used for rest C5 light hydrocarbon gas. The utility model is composed of an injection nozzle, a burner, the frame of the range, etc. The utility model is characterized in that the injection nozzle is not provided with an air door; a current guide groove is arranged in the air cavity of the burner; the liquid rest C5 dropping from the injection nozzle is led to a burner head and then is burned for secondary gasification, which solves the problem of liquid dropping of the special range for the general rest C5 light hydrocarbon gas. The safety of using the rest C5 light hydrocarbon gas as civil fuel is improved.

Description

Liquefied petroleum gas range

The utility model belongs to a kind of liquefied petroleum gas kitchen range.

The raffinate carbon-5 that produces in the petroleum refining is used for domestic fuel, is a better approach that rationally utilizes carbon five resources and solve the civilian carbon four petroleum gas fuel deficiencies of China.Through research and development in recent years, smooth combustion and microthermal climate that people have solved raffinate carbon-5 substantially descend problems such as burning.In order to make that raffinate carbon-5 also can smooth combustion under lower temperature, generally be with air pump in steel cylinder in the liquid raffinate carbon-5 drum advance air and carry out forced gasification, consequent air and raffinate carbon-5 gaseous mixture are picked on the kitchen range of special use again and are burnt.But because the gasification point of raffinate carbon-5 lighter hydrocarbons gas is higher, add reasons such as the drag losses of pipeline, the destruction of passing through the pressure-reducing valve back balance and liquid foam entrainment, cause the liquid raffinate carbon-5 that in nozzle, can freeze-out when using, these liquid raffinate carbon-5s can be from the air door holes of nozzle and are oozed along the air door of jet hole and burner, thereby become disaster hidden-trouble.

The purpose of this utility model provides a kind of liquefaction raffinate carbon-5 lighter hydrocarbons gas special stove that improves structure, and the air door place that it has solved general liquefaction raffinate carbon-5 lighter hydrocarbons gas special stove can ooze the problem of liquid carbon five.

In fact, because the raffinate carbon-5 lighter hydrocarbons are difficult to gasification than carbon four lighter hydrocarbons, must in steel cylinder, rouse air in the liquid raffinate carbon-5 to carry out forced gasification with air pump when using as previously mentioned, thereby what be sent to burner is raffinate carbon-5 and air Mixture, wherein contain combustion-supporting oxygen, there is no need to offer again the air door hole on the burner nozzle.Therefore, the utility model is designed to the nozzle tube wall to seal, and has cancelled the air door hole on the general burner nozzle.In addition, for the liquid raffinate carbon-5 that prevents to condense oozes along jet hole and burner air door, in the burner air cavity, also be provided with a drainage trough.The origin or beginning of drainage trough is positioned at jet expansion, and end is positioned at burner air cavity middle part, and origin or beginning is a little more than end.The cross section of drainage trough generally can be " V " shape or " U " shape.The liquid raffinate carbon-5 that oozes from jet hole will flow to burner air cavity middle part along drainage trough, and flow to combustion head along the air cavity wall that tilts.Because kitchen range combustion head in use have higher temperature, accumulate in this liquid raffinate carbon-5 second gasification combustion.

Compared with the prior art, the utility model has been owing to done the improvement of above-mentioned two aspects, thereby solved the drip problem of general raffinate carbon-5 special stove, improved the security of raffinate carbon-5 lighter hydrocarbons gas as domestic fuel.

Accompanying drawing has been showed an embodiment of the present utility model, and this is the generalized section that the cooker burner afterbody comprises nozzle.

Among the figure, the 1st, nozzle, the 2nd, burner, the 3rd, drainage trough, the 4th, the burner air cavity, the 5th, burner moves air flap, and the 6th, decide air flap.

Claims

1, a kind of liquefaction raffinate carbon-5 lighter hydrocarbons gas stove is made up of parts such as nozzle, burner, kitchen range framves, it is characterized in that:
