Abstract
The utility model discloses an energy-saving flame igniter which is suitable for mixing burning of water-coal slurry and diesel oil and is composed of an atomizing spraying nozzle mechanism of a water-coal slurry inflamer and a diesel oil thrust jet arranged inside the atomizing spraying nozzle mechanism. The diesel oil can be guided to the forefront end of the atomizing spraying nozzle mechanism from a compressed air channel to be mixed and atomized in a cross way with compressed air to enter a hearth for burning. After the hearth is preheated, a diesel oil channel is closed, and then the water-coal slurry can burn separately. The utility model has reasonable design, simple structure, stable burning and high efficiency, enables the diesel oil and the water-coal slurry fogdrops to be mixed evenly and can obviously save the ignition expense.
Description
Technical field
The utility model relates to a kind of combustion ignition device, the energy-saving ignition device of particularly a kind of suitable water-coal-slurry, diesel oil mixed combustion.
Background technology
Water-coal-slurry is a kind of novel clean coal fuel, can improve burning of coal efficient as the fuel of Industrial Stoves or boiler, reduces fuel cost, and can be as fuel oil pumping, atomizing, burning.From the angle of environmental protection, the water-coal-slurry hot-water boiler is low to the ature of coal requirement of water-coal-slurry, compares with coal-powder boiler, and flue dust and sulphur concentration reduce greatly, and boiler is over-emitting black exhaust not, NO
xDischarge also very low.Therefore, water-coal-slurry has a wide range of applications as a kind of novel alternative oil or the clean fuel of coal.Because the combustion conditions of water-coal-slurry is strict more than fuel oil and fire coal, just can light and smooth combustion after must in less space, reaching 850 °～900 ° temperature, lighting of water-coal-slurry will improve fire box temperature earlier by other fuel, just can make water-coal-slurry smooth combustion, therefore simplifying igniter, shortening the water coal slurry burner duration of ignition and reduce the igniting cost is technological difficulties always.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, and a kind of easy and simple to handle, long service life and the good durable and efficient water coal slurry burner of environment protecting are provided.
The technical solution of the utility model is: the energy-saving ignition device of a kind of suitable water-coal-slurry, diesel oil mixed combustion, the atomizer mechanism that comprises water coal slurry burner, it is characterized in that: described atomizer mechanism comprises interconnective anterior cannula and rear sleeve, be positioned at anterior cannula and be disposed with spray chamber and atomization chamber from front to back, on the port of anterior cannula shower nozzle is installed, the inboard that is positioned at shower nozzle is equipped with impact block towards spray chamber; The rear end of described atomization chamber is connected with water-coal-slurry input pipe in being installed in rear sleeve by the front and back casing joint; The tube wall that is positioned at rear sleeve is provided with compressed air inlet and diesel oil inlet; Described compressed air inlet is communicated with atomization chamber by admission line in the casing joint before and after being arranged on and the primary atomization air intlet that is arranged on the atomization chamber, and the described diesel oil diesel oil jet pipe interior with being arranged on anterior cannula and rear sleeve that enter the mouth is connected.
The utility model compared with prior art has the following advantages:
The utility model is reasonable in design, and is simple in structure, can make that oil, water-coal-slurry droplet mix, flameholding and efficient height, can significantly save the igniting expense.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model diesel oil jet pipe 12.
Fig. 3 is the right view of Fig. 2.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises the atomizer mechanism of water coal slurry burner, described atomizer mechanism comprises interconnective anterior cannula 1 and rear sleeve 2, be positioned at anterior cannula 1 and be disposed with spray chamber 14 and atomization chamber 4 from front to back, shower nozzle 6 is installed on the port of anterior cannula 1, and the inboard that is positioned at shower nozzle 6 is equipped with impact block 3 towards spray chamber 14; The rear end of described atomization chamber 4 is connected with water-coal-slurry input pipe 7 in being installed in rear sleeve 2 by front and back casing joint 5; The tube wall that is positioned at rear sleeve 2 is provided with compressed air inlet 8 and diesel oil inlet 9; Described compressed air inlet 8 is communicated with atomization chamber 4 by admission line in the casing joint 5 before and after being arranged on 10 and the primary atomization air intlet 11 that is arranged on the atomization chamber 4, and the described diesel oil 9 diesel oil jet pipes 12 interior with being arranged on anterior cannula 1 and rear sleeve 2 that enter the mouth are connected.
As shown in Figures 2 and 3, the front portion of described diesel oil jet pipe 12 is annular body, and described annular body is provided with spout 13, and plug 15 is installed on the front port of diesel oil jet pipe 12.
During the utility model work, diesel oil through enter the mouth 9 and compressed air channel enter atomizing gun 4, and by 13 ejections of the spout on the ring pipe, mix through intersecting with compressed air, form the blister mixture from nozzle 6 ejections, the rapid dilatation of bubble is split the broken uniform fine drop that is with diesel oil, enters combustion chambers burn.After diesel combustion a period of time makes burner hearth reach uniform temperature, add a certain amount of water-coal-slurry through water-coal-slurry input pipe 7, utilize diesel oil, air mixture that water-coal-slurry is atomized and pass through nozzle 6 and spray, because diesel oil and water-coal-slurry are being mixed near the exit, can produce oil, the mixed uniformly fine drop of water-coal-slurry and smooth combustion when fire box temperature is low.After burner hearth reaches the water-coal-slurry ignition temperature, close the diesel oil passage, water-coal-slurry begins independent burning, and ignition process is finished.
