Description
Technical field
The utility model relates to burner field, be specifically related to a kind of burner of coal tar.
Background technology
Energy shortage now, environmental pollution has seriously become the factor of restriction economic development, due to fuel oil resource scarcity, at present conventional industry substitutes oil and take coal and water-coal-slurry as main, but there is respectively poor fluidity in coal and water-coal-slurry, the shortcoming that pollutant output is too high, and coal tar is the product of coking industry, to produce plastics, synthetic fibers, dyestuff, rubber, medicine, the important source material of exotic material etc., can be used for synthesizing multiple industrial goods, there is cheap advantage, if but adopt the directly method of burning, in its combustion product, pollutant load exceeds standard, if without processing, do not allow burning, during coal tar burning, may there is white fire, the contamination phenomenon such as black smoke, can not completing combustion, cannot be as industrial fuel, so design a kind of burner of coal tar or necessary.
Summary of the invention
For the deficiency existing in prior art, the utility model object is the burner that is to provide a kind of coal tar, reasonable in design, fuel cost is low, and good economy performance can make coal tar completing combustion, and the pollutant load in flue gas is in environment allowed band, ignition temperature and the oxygen content of coal tar are adjustable, have guaranteed the stability of burning, and product is clean.
To achieve these goals, the utility model is to realize by the following technical solutions: a kind of burner of coal tar, comprises coal tar oil inlet pipe, burner, oxygen intake pipe, combustion furnace, temperature controller, temperature transmitter, O
2consistency transmitter, O
2consistency controller, combustion valve and oxygenating tube valve, be provided with combustion valve on coal tar oil inlet pipe, and coal tar oil inlet pipe is connected with burner, and burner, oxygen intake pipe are all connected with combustion furnace, is provided with oxygenating tube valve, O on oxygen intake pipe
2consistency transmitter, temperature transmitter are all connected with combustion furnace, O
2consistency transmitter and O
2consistency controller is connected, O
2consistency controller connects oxygenating tube valve, and temperature transmitter is connected with temperature controller, and temperature controller connects combustion valve.
The beneficial effects of the utility model: reasonable in design, fuel cost is low, good economy performance, can make coal tar completing combustion, and the pollutant load in flue gas is in environment allowed band, ignition temperature and the oxygen content of coal tar are adjustable, the stability of having guaranteed burning, product is clean.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the utility model in detail;
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
With reference to Fig. 1, this specific embodiment by the following technical solutions: a kind of burner of coal tar, comprises coal tar oil inlet pipe 1, burner 2, oxygen intake pipe 3, combustion furnace 4, temperature controller 5, temperature transmitter 6, O
2consistency transmitter 7, O
2consistency controller 8, combustion valve 9 and oxygenating tube valve 10, on coal tar oil inlet pipe 1, be provided with combustion valve 9, coal tar oil inlet pipe 1 is connected with burner 2, and burner 2, oxygen intake pipe 3 are all connected with combustion furnace 4, on oxygen intake pipe 3, be provided with oxygenating tube valve 10, O
2consistency transmitter 7, temperature transmitter 6 are all connected with combustion furnace 4, O
2consistency transmitter 7 and O
2consistency controller 8 is connected, O
2consistency controller 8 connects oxygenating tube valve 10, and temperature transmitter 6 is connected with temperature controller 5, and temperature controller 5 connects combustion valve 9.
This specific embodiment first makes coal tar through coal tar oil inlet pipe 1, after coal tar is atomized in burner 2, comprise You Heshui simultaneously, aqueous dispersion, in oil, forms water-in-oil type molecular radical, because the boiling point of water is lower, after being heated, water first volatilizees, seethes with excitement, pressure is increased, blast, i.e. " microexplosion " phenomenon; The volume of oil droplet reduces, and increases with the contact area of air, makes fuel more even with mixing of air, impels combustion reaction efficiency to increase.
In combustion reaction process, in order to guarantee O
2sufficient; this specific embodiment is provided with oxygen intake pipe 3; delivery of supplemental oxygen tolerance at any time; oxygen is mixed with the speed of diffusion enough large with elaioleucite; combustion process is comparatively fast carried out; thereby coal tar is more easily burnt, burn also more completely, the coal tar being atomized supplements a certain amount of O through oxygen intake pipe 3
2, after igniting, send into combustion furnace 4 and burn, for it is fully burnt, control peroxide amount at 1.05-1.20, ignition temperature 900-1100 ℃, the key component of the flue gas of generation is CO
2, H
2o, volume fraction is respectively 13% and 8% left and right, and O
2volume fraction be 7% left and right, be to improve O
2volume fraction, should carry out oxygenating to combustion system.
In combustion process, O
2whether magnitude relation is complete to the burning of coal tar, and temperature directly affects the composition of combustion product, for the burning to coal tar is in good time controlled, guarantees ignition temperature and O
2stablizing of volume fraction, this specific embodiment is provided with control system, comprises O
2the controller of volume fraction and coal tar ignition temperature, when temperature transmitter 6 detects ignition temperature rising, temperature controller 5 turns down fuel valve 9, on the contrary temperature controller 5 leaves greatly fuel valve 9; Work as O
2consistency transmitter 7 detects O
2when volume fraction increases, O
2consistency controller 8 turns down oxygenating tube valve 10, on the contrary O
2consistency controller 8 is opened greatly oxygenating tube valve 10, O while making like this coal tar burning
2abundance, to guarantee completing combustion, also makes ignition temperature moderate in addition, up to standard to guarantee the pollutant producing, thereby guarantees that coal tar has good combustion characteristics.
This specific embodiment is reasonable in design, and fuel cost is low, good economy performance, can make coal tar completing combustion, and the pollutant load in flue gas is in environment allowed band, ignition temperature and the oxygen content of coal tar are adjustable, the stability of having guaranteed burning, product is clean.
