Description

Combined type heavy oil combustion machine

Technical field

The utility model relates to a kind of combustor, particularly a kind of combined type heavy oil combustion machine.

Background technology

The Light Oil Burning Machine of existing market, as diesel combustion machine, combustion of natural gas machine, gas-fired machine, all be to utilize high-tension electricity to produce spark, the above-mentioned combustible substance of igniting, and the combustor of heavy oil also utilizes this operation principle to ignite, but about must the about 1.5MPa of high oil pressure, about about 120 degree of high oil temperature, and want high-quality heavy oil 180#.There is a kind of heavy oil combustion machine then to utilize the surplus warm spot fire of burner hearth in addition, like this, after the burner hearth cooling, just can not have lighted a fire, and, when lighting a fire with torch by hand again, can produce a large amount of black smokes, both be inconvenient to light a fire, also contaminated environment.In addition, the diesel-fuel price costliness is generally about 6000 yuan/ton, needing to be used for the combustor of a large amount of burnings, and obviously the cost height is wasted big.Existing heavy oil combustion machine, as imported product, because its fault of construction needs high oil temperature, oily temperature will reach 120 degree, needs high oil pressure, and oil pressure will reach 1.5MPa, and needs high-quality heavy oil, its effect of competence exertion.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of and can lights a fire automatically, the no black smoke of lighting a fire, and only needs combined type heavy oil combustion machine heavy oil, that combustion efficiency is good of low-temp low-pressure and general oil.

The technical scheme that its technical problem that solves the utility model adopts is:

Combined type heavy oil combustion machine, comprise high-pressure air hose, be positioned at the low pressure airduct of high-pressure air hose central interior, be positioned at the heavy oil pipeline of low pressure airduct central interior, the high-tension electricity fire maker that is provided with gas pipeline at the following rear of heavy oil pipeline and is used to light a fire, the rear of described high-pressure air hose is provided with a high-pressure blast import, the inferoanterior that the rear of described low pressure airduct is positioned at the high-pressure blast import is provided with a low-pressure air import, the low-pressure air import is positioned at the last rear of the outlet of gas pipeline, the front end of described heavy oil pipeline is provided with the heavy oil atomizer, the rear end of described high-pressure air hose and low pressure airduct is all sealed, and front end is air outlet.

Technique scheme also can have following improvement project: described low-pressure air import departs from the axis setting of low pressure airduct.

The beneficial effects of the utility model are: because the high-tension electricity fire maker that is provided with gas pipeline and is used to light a fire at the following rear of heavy oil pipeline, and there is low-pressure air that gas flame is blowed to from the heavy oil mist of heavy oil atomizer ejection in the low pressure airduct, light heavy oil with gas flame, dry to heavy oil flame by high-pressure air hose again, to promote the heavy oil flame combustion, make heavy oil completing combustion, so the utility model can be lighted a fire automatically, do not need manually to light a fire with torch, igniting is convenient, and heavy oil combustion is effective, and burning does not have black smoke.Because adopt the gas flame igniting, combustion gas can be used liquefied gas, natural gas, coal gas etc., combustion gas all can be got spark ignition by the high-tension electricity fire maker, promotes combustion gas fully to burn by low-pressure air again, so fuel gas buring does not have black smoke, and the no black smoke of lighting a fire.In addition, owing to adopt the gas flame igniting, it is much easier to light a fire, and the high pressure wind energy guarantees that heavy oil combustion is abundant, so that the oily gentle oil pressure of heavy oil does not need is too high, oil does not need very good yet, only need the heavy oil of low-temp low-pressure and general oil to get final product, the oily temperature of common required heavy oil is that oil pressure is about 0.15MPa about 80 degree, like this, can save energy.In addition, the price of heavy oil is generally about 3000 yuan/ton, than diesel oil considerably cheaper, can save production cost greatly, improves the market competitiveness.

Description of drawings

Below in conjunction with drawings and embodiments the utility model is further specified.

Fig. 1 is an axial sectional structure schematic diagram of the present utility model;

Fig. 2 is the structural representation of cross section of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2, combined type heavy oil combustion machine, comprise high-pressure air hose 1, be positioned at the low pressure airduct 2 of high-pressure air hose 1 central interior, be positioned at the heavy oil pipeline 3 of low pressure airduct 2 central interior, the high-tension electricity fire maker 5 that is provided with gas pipeline 4 at the following rear of heavy oil pipeline 3 and is used to light a fire, the rear of described high-pressure air hose 1 is provided with a high-pressure blast import 6, the inferoanterior that the rear of described low pressure airduct 2 is positioned at high-pressure blast import 6 is provided with a low-pressure air import 7, low-pressure air import 7 is positioned at the last rear of the outlet of gas pipeline 4, the front end of described heavy oil pipeline 3 is provided with heavy oil atomizer 8, described high-pressure air hose 1 all seals with the rear end of low pressure airduct 2, and front end is air outlet.

Technique scheme also can have following improvement project: described low-pressure air import 7 departs from the axis setting of low pressure airduct 2, like this, the wind that enters low pressure airduct 2 from high-pressure air hose 1 can forwards rotate propelling towards the periphery of low pressure airduct 2, also waft when allowing gas flame spray forward, so conveniently light from the atomizing heavy oil of heavy oil atomizer 8 ejections to the axle center.

The utility model can comprise that also one is used to control the gas pipeline autocontrol valve of gas flame length burning time, be 3 seconds, 4 seconds or 5 seconds the burning time of setting gas flame, can be in this time period to light atomizing heavy oil, after having spent this time period, the gas pipeline autocontrol valve cuts out automatically, and gas flame extinguishes automatically.The duration of valve opening length of gas pipeline autocontrol valve is adjustable.

In addition, the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
