Description

A kind of energy saver improving heavy oil utilization rate

Technical field:

The present invention relates to heavy oil technical fields, in particular to improve the energy saver of heavy oil utilization rate.

Background technique:

Heavy oil is also known as heavy oil, and heavy oil is that crude refining remains in the undermost residue oil of destilling tower in the process, Or the tower bottom oil by light oil cracking process institute output, it is referred to as heavy oil, residual oil.Heavy oil calorific value is about in 39000- It is a kind of very high fuel oil of calorific value between 41000KJ/KG, since calorific value is high, price is relatively cheap, storage is comparatively safe Feature, it has also become boiler, internal combustion engine in the fields such as food, feed, weaving, building materials, metallurgy, ceramics, power-generating industry, sea-freight and The main fuel of turbine LP rotors.

The composition of heavy oil is extremely complex, has been mingled with the impurity such as ash, gluey pitch, moisture, greasy filth, sulfide, viscosity is high, Impurity is more, sulfur content is high, so to transport heavy oil must just possess heating equipment, and to heavy oil continuous heating, otherwise heavy oil without Method transport, heavy-oil heating to certain temperature make oil droplet form misty oil particles, i.e., under certain pressure and air distribution by nozzle ejection So that the biggish big oil particles of volume is also will disperse into the oil particles of miniaturization, all tiny oil particles can be connect as far as possible with air It touches and obtains sufficient oxygen full combustion.

Gluey pitch particle in heavy oil is larger, when passing through nozzle so that be wrapped in the big oil particles of gluey pitch without Method is dispersed into mist particles, and since particle is excessive, contained amount of oxygen is also insufficient, causes incomplete combustion, exhaust gas discharge When can be mingled with the suspended particulate without burning, that is, the black smoke being commonly called as, this phenomenon can because the temperature of combustion chamber is higher and All the more serious, not only waste of energy, increases operating cost, and will cause serious air pollution, generates serious environmental issue.

Moisture content in heavy oil is generally between 0.3-2.0%, if do not homogenized with heavy oil first, water and heavy oil will Generate incomplete emulsion, when the heavy oil that not exclusively emulsifies is by being heated to close to 100 degree, moisture can rapid vaporization become water Steam, the heavy oil moment cutout for spraying nozzle, and cause flame-out or be tempered, it will cause great work accident, even if constantly Fire, and water can absorb the heat of surrounding in vaporescence, reduce the temperature of flame and mist of oil, will also result in flame can not ignite Mist of oil and cause part heavy oil that can not burn, formed black smoke, cause serious environmental pollution.

Generally 2% or so, these ash contents and greasy filth can aggravate the abrasion to nozzle for ash content and greasy filth content in heavy oil, Increase nozzle diameter, nozzle atomization effect is with using the time to lengthen, and worse and worse, result causes to fire atomizing effect naturally It burns not exclusively, forms black smoke, cause serious environmental pollution.

Summary of the invention:

The purpose of the present invention is providing heavy oil energy saving device in view of the deficiencies of the prior art, it can solve heavy oil combustion Lag, coking, over-emitting black exhaust practical problem, improve heavy oil combustion rate, further increase boiler thermal efficiency, while also making to run Equipment and the service life of relevant device extend, and ensure to produce and operate normally, and are truly realized energy conservation and environmental protection.

In order to achieve the above objectives, the present invention adopts the following technical scheme:

It includes heavy oil pipeline, ENERGY-SAVING AGENT FOR pipeline, colloid mill, and heavy oil pipeline, ENERGY-SAVING AGENT FOR pipeline are connected respectively to colloid mill Input terminal, the output end of colloid mill has output channel, heavy oil and ENERGY-SAVING AGENT FOR worn into nano-scale particle using colloid mill, made The moisture obtained in heavy oil homogenizes with heavy oil, and the gluey pitch in heavy oil, ash content, greasy filth is made all to wear into tiny particle, will not Nozzle is impacted, and cooperates heavy oil particle more preferably with oxygen, full combustion, to improve combustion heat value.

The input terminal of the colloid mill is connected with the first reflux line.

The output channel is connected with the second reflux line.

Frequency conversion metering pump is connected separately on the heavy oil pipeline, ENERGY-SAVING AGENT FOR pipeline.

Flowmeter is connected on first reflux line, the second reflux line.

Flowmeter is connected on the output channel.

The beneficial effects of the present invention are relatively simple for structure, using effect clearly, has environmental advantages.

Detailed description of the invention:

Fig. 1 is structural schematic diagram of the invention

Specific embodiment:

The present invention will be further described below with reference to the drawings.

As described below is only better embodiment of the invention, is not intended to limit the scope of the present invention.

See attached drawing 1, the present invention includes heavy oil pipeline 10, ENERGY-SAVING AGENT FOR pipeline 20, colloid mill 30, heavy oil pipeline 10, ENERGY-SAVING AGENT FOR Pipeline 20 is connected respectively to the input terminal of colloid mill 30, and the combustion rate of heavy oil can be improved in ENERGY-SAVING AGENT FOR, there is many ENERGY-SAVING AGENT FORs at present Product, therefore not to repeat here；Heavy oil and ENERGY-SAVING AGENT FOR are ground into nano-scale particle in colloid mill 30, and make the water in heavy oil Divide and homogenize with heavy oil, so that the gluey pitch in heavy oil, ash content, greasy filth is all worn into tiny particle, shadow will not be caused to nozzle It rings, and cooperates heavy oil particle more preferably with oxygen, full combustion, to improve combustion heat value；The output end of colloid mill 30 has There is output channel 40, heavy oil is supplied by combustor burning by output channel 40.

The present invention separates ENERGY-SAVING AGENT FOR and the input of heavy oil, the behaviour different from the past directly poured into ENERGY-SAVING AGENT FOR in heavy oil tank Make mode, when not working, heavy oil can be separated individually with ENERGY-SAVING AGENT FOR, will not be mixed.

The input terminal of the colloid mill 30 is connected with the first reflux line 50, can will be fired by the first reflux line 50 The part heavy oil of burning machine flows back into colloid mill 30, refines heavy oil particle again.

The output channel 40 is connected with the second reflux line 60, can be by the second reflux line 60 by combustor Part heavy oil, which is fed again into supply in combustor back up through output channel 40, to burn.

It is connected separately with frequency conversion metering pump 70 on the heavy oil pipeline 10, ENERGY-SAVING AGENT FOR pipeline 20, is controlled by computer defeated Enter amount.

Flowmeter 80 is connected on first reflux line 50, the second reflux line 60.

Flowmeter 80 is connected on the output channel 40.

The work of frequency conversion metering pump 70 can be automatically controlled, using external computer with control by the numerical value of flowmeter 80 The input quantity of heavy oil and ENERGY-SAVING AGENT FOR.

Due to the high temperature action that burning generates, continuous gasification effect can be formed in 280 degree, keeps heavy oil bulky grain continuous It is continuous broken, reach micron order atomizing effect.

After apparatus of the present invention are used continuously four months, boiler thermal efficiency can save 5.13% or so than professional standard, say Bright heavy oil combustion efficiency significantly improves, and the heating surface incrustation of running equipment is reduced or disappeared, and heat exchange efficiency improves, and running equipment is whole Body power improves 15% or so.

The present invention can solve the problem of running equipment filter net jam, reduce the abrasion to oil pump and nozzle, extend oil pump And the service life of nozzle, make to be formed the gluey pitch in the heavy oil of nanoscale oil group, greasy filth, water droplet and participate in burning, increases heat Value.
