Abstract

The utility model discloses a multi-purpose efficient electric preheating oil gasifying stove, comprising a gas chamber, a fire tray, a gasifying tube, an ejector tube, a regulating valve, a heating wire, a casing, etc. The utility model is characterized in that a heating wire is arranged between the fire tray and the gasifying tube to heat the gasifying tube and ignite the stove directly; the gas chamber is a sandwich layer which can be filled with filler or pumped to vacuum for thermal insulation or can serve as a fuel surge chamber; the U-shaped ejector tube is coupled in the gas chamber aslant after being led out along the gasifying tube so swirling flow can be generated when the mixed gas goes into the gas chamber and the mixed gas can be homogeneous distributed. The utility model has the advantages that the structure is simple; the thermal utilization rate is high; the combustion is homogeneous.

Description

Electric preheating multipurpose efficient fuel gasification stove

The utility model relates to a kind of fluid fuel gasification burner with the electric energy heating

The gasification burner of liquid fuels such as burning kerosene, diesel oil is by the pressure in the oil tank oil to be entered steam chest along pipeline input generating tube after vaporization to burn again.Normally earlier with kerosene or alcohol preheating generating tube, this preheating method is progressively replaced by the electric preheating method because of seriously polluted this stove.As Chinese patent CN2077523U disclosed " electric preheating fuel gasification stove ", be that the direct microheater of being controlled by power switch of packing on oil pipe carries out preheating; CN2067375U disclosed " with the kerosene gasification burner of electric preheating " adopts the U-shaped oil pipe, and preheating is carried out in the outside that the interior electric preheating cover that the electricity silk arranged is enclosed within two U-shaped oil pipes.Above-mentioned electric preheating method is removed the structure complexity, outside the cost height, and can not produce naked light and the fiery device of need setting up an office in addition.Known gasification burner is normally directly delivered in the steam chest of attemperator by induction tunnel through the mixed steam of vaporization, and this stove also exists flame inhomogeneous, the not high shortcoming of heat utilization efficiency.

It is a kind of simple in structure that the purpose of this utility model is to provide, and do not need the fiery device of setting up an office in addition, and combustion flame is even, the electric preheating fuel gasification stove that heat utilization efficiency is high.

The scheme that the utility model purpose realizes is: in the fuel gasification stove that includes compositions such as steam chest, tray for combustion, generating tube, induction tunnel, control valve, dish has the heating wire of external power supply on the tray for combustion between tray for combustion and the generating tube, directly heats generating tube and igniting; Or/and steam chest adopts interlayer and filler or vacuumize into thermal insulation layer or make the surge chamber of fuel in interlayer, reducing the interior heat energy of steam chest outwards distributes or the while heated liquid fuel, induction tunnel takes the shape of the letter U, and draws rear-inclined along generating tube and inserts the mixed steam that makes in the circular steam chest through vaporization and produce bumpy flow when entering steam chest.

The utility model gasification burner compared with prior art has following advantage: simple in structure; Direct-fire after the heating wire preheating and the fiery device that do not need to set up an office in addition; The heat radiation of heat preserving type steam chest is few, vaporizes sufficient combustion, the utilization rate of raising heat energy; Mixed steam enters steam chest with cyclone mode and evenly distributes, and makes burning evenly.The present invention removes generating tube importing liquefied gas and can be changed into liquefied gas furnace; Connect power supply and become electric furnace; Can electric oil when wind is big, electric dual-purpose, fire prevention is extinguished and is ensured safety.Become multi-use.

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the cutaway view of an embodiment of the utility model.

Fig. 2 is the vertical view of Fig. 1 embodiment steam chest and induction tunnel.

Fig. 3 is the cutaway view of another embodiment of the utility model.

Gasification burner steam chest 8 is installed in the enclosure among Fig. 1 and 2, fills asbestos insulation material 12 in 8 one-tenth interlayers of steam chest, interlayer, and tray for combustion 7 is set up in steam chest 8 upper ends, and heating wire 5 is put on tray for combustion 7 upper berths, and heating wire 5 inserts the electric mortiser 11 that is fixed on the shell 1.Generating tube 6 is above heating wire 5, and the one head is connected with the oil-in 10 that exposes on the shell 1, and by control valve 9 control oil masses, an other end and a U-shaped induction tunnel 2 are connected.Induction tunnel 2 has air door 3 near generating tube 6 places, and ends in steam chests 8 are inserted in 2 one-tenths skewed its other ends of induction tunnel, makes to be swirl shape through the mixed steam of vaporizing and mix with air and to enter steam chest 8.Be connected to oil exit pipe 13 in the bottom surface of steam chest 8 and get rid of the oil that is trapped in the steam chest 8.Pillow pin 4 is housed on shell 1.During use, insert power supply at electric mortiser 11 places, treat that heating wire opens the oil tank switch to the generating tube preheating when rubescent and make oil enter generating tube 6, oil enters steam chest 8 after generating tube 6 heating vaporizations, mix gas in the steam chest and promptly cause burning once the tray for combustion 7 apertures contact heating wire naked light of gushing out.After finishing igniting attaching plug is extracted.

Another embodiment difference of Fig. 3 is that petroleum pipeline 14 is inserted steam chest 8 interlayer oil-ins 15, and steam chest 8 interlayer oil-outs 16 are connected by conduit and oil-in 10 again.
