Description

Combustion gas supply

The utility model belongs to a kind of gas-fired equipment, particularly relates to a kind of air mixture generation equipment that utilizes light oil for raw material.

The Chinese patent of Granted publication CN2136246, patent No. ZL92233303.3 discloses a kind of gas producing and supply machine, and this machine equipment is simple, and is convenient, practicality, but also have certain deficiency, it heats water by electric heater, hot water enters radiator, oil is heated by the heat of heat sink radiates again, adopts such post bake mode, the thermal efficiency is low, big energy-consuming, in addition, because the temperature of water is lower, it is slow to cause oil to heat up, the oil liquid temperature inequality, and gas output is few.It is not provided with and blasts compressed air in the feedstock oil and further with air and the well-mixed device of oil vapour, make the combustion gas mixing of generation inhomogeneous, can cause combustion instability, do not mix enough air in addition in the oil vapour, easily cause high-temperature fuel gas in pipeline, to condense in a large number and produce backflow, so just caused the reduction of efficient.

The purpose of this utility model be to provide a kind of can be with the gasifier section that oil vapour and air fully mix, gas producing efficiency is high.

Its technical scheme is: a kind of gas producing and supply machine, mainly comprise reactor, place heater and oil storage tank in the reactor, oil storage tank has an oil pipe to be connected with reactor, it is characterized in that: described heater is a spiral tube, one termination, one steam generator, the other end also links to each other with steam generator by return duct, there is a vacuum tank arrival end to be connected to air compressor, the port of export is connected with gas jet pipe in oil storage tank and the reactor by pipeline, and reactor top has an escape pipe to link to each other with gs-oil separator.

Described steam generator is the airtight water tank that electric heater is housed, and there is a ball-cock assembly water inlet, has spiral tube two ends to be connected with steam generator in the vacuum tank.

Have a liquid level tube to be connected by communicating pipe with reactor, a dividing plate is equipped with at middle part, gs-oil separator longitudinal section, and the dividing plate downstream direction is slick and sly " L " shape.

One temperature sensor is arranged at the bottom of reactor, and a pressure sensor is arranged at top, and the upper and lower side of liquid level tube respectively has a liquid level sensor, and a liquid level sensor is arranged at the bottom of oil storage tank.

Because the superheated steam that the utility model adopts steam generator to produce directly heats oil by spiral tube, the superheat steam temperature height, spiral tube is again among fluid, fluid quick heating and temperature are even, increase gas production, owing to adopted gas jet pipe and vacuum tank, on the one hand fluid is stirred, be in fluidized state, reduced the surface tension of liquid level, the gas of generation is overflowed as early as possible, can equably compressed air and oil vapour be mixed on the other hand, reduce the dew point of combustion gas, combustion gas is difficult for condensing in pipeline, reduce and reflux, improved the quality of combustion gas.Owing to be provided with gs-oil separator, the tiny oil droplet that carries in the combustion gas can be separated, reduce the content of the oil that do not gasify in the combustion gas, further improve the combustion gas quality.

Further specify the utility model below in conjunction with accompanying drawing and by embodiment:

Fig. 1 is the structural representation of embodiment;

Fig. 2 is the A-A generalized section of Fig. 1;

Fig. 3 is the plan structure schematic diagram of embodiment.

Embodiment: as Fig. 1, shown in 3, reactor 1 links to each other by oil pipe 3 with oil storage tank 2, one magnetic valve 16 is installed on the oil pipe 3, one spiral tube 4(is arranged in order to improve its heat transfer efficiency in the reactor 1, the most handy copper pipe coiled), the upper end links to each other with the top of a steam generator 5, steam generator 5 is returned by return duct 6 in the lower end, steam generator is the airtight water tank that electric heater 7 is equipped with in the bottom, the water inlet place is provided with a ball-cock assembly 8, in order to the control water level, vacuum tank 9 porch link to each other with one group of air compressor 10, the exit links to each other by pipeline 11 and oil storage tank 2 and the 2-3 group gas spray pipe 13 that is positioned at reactor 1 bottom, jet pipe 13 is shape as shown in Figure 2, and every arm has some aperture 14(gas jet pipes also to can be other shape such as polygon, circular, ellipse and other obform body), there are a spiral tube 15 two ends to link to each other with steam generator 5 respectively in the vacuum tank 9.Reactor 1 upper end has an escape pipe 17 to insert in the gs-oil separators 18, and middle part, gs-oil separator 18 longitudinal sections downstream direction has a dividing plate 19 that is slick and sly " L " shape, and gs-oil separator 18 is connected to a combustion gas escape pipe 20.One pressure sensor 21 is arranged in the upper end of reactor 1, one temperature sensor 22 is arranged at the bottom, have a liquid level tube 23 to be linked to each other by communicating pipe 24,25 with reactor 1, in the upper end and the bottom of liquid level tube liquid level sensor 26,27 is housed, a liquid level sensor 28 is arranged at the oil storage tank bottom.
