Description
Technical field
The utility model relates to anode-baking furnace field, relates in particular to a kind of anode-baking furnace flame injection device.
Background technology
Roasting technique control is the most complicated most important part of calcination department, wherein the key link is exactly the burning control of natural gas, in production reality, often because the malcombustion of natural gas causes non-uniform temperature in quirk, fire path temperature deviation is larger, to roaster service life, baked anode quality, all can affect greatly.
Causing two key factors of natural gas malcombustion is that gas pressure is unstable, and combustion system amount of supplied air is undesired.
According to burning of gas characteristic, the size of the outlet fuel gas flow speed of burner, directly affect the intensity of flame and the burning velocity of burner, and the two directly has influence on the height of furnace chamber fire path temperature, if gas pressure is unstable in combustion process, can cause the intensity of combustion flame unstable, when gas pressure is lower, combustion of natural gas flame is umbrella, and spray penetration is more shallow, can cause non-uniform temperature in quirk, fire path temperature deviation is larger.As shown in Figure 2, in combustion of natural gas process, because each quirk magnetic valve adjustment cycle is identical, magnetic valve opening time is synchronous, and each control cycle magnetic valve in early stage is synchronously opened, cause gas pressure to reduce, later stage, gas pressure progressively raise along with magnetic valve closes, and front and back gas pressure difference is larger, gas pressure is unstable, causes non-uniform temperature in quirk.
In combustion of natural gas process, if air supply surplus, exhaust gas volumn increases, a large amount of flue gases can be taken away part heat, causing fire path temperature to reduce, increased heat loss due to exhaust gas, is that the thermal efficiency of burner declines, result reduces fire path temperature, if air is under-supply, natural gas occurs superfluous, can not fully burn, cause waste of fuel, and can be to cleaning system build-up of pressure.
Utility model content
The technical problems to be solved in the utility model is: a kind of anode-baking furnace flame injection device that can improve combustion of natural gas state is provided.
For the technical scheme that addresses the above problem employing is: anode-baking furnace flame injection device comprises at least two gas spray head and point bronchus identical with gas spray head quantity, divide bronchus to be connected with gas spray head, gas spray head comprises nozzle body, nozzle body inside is prolonged nozzle body and is axially provided with the fuel gas hole and the jet chamber that are interconnected, and nozzle body inside is prolonged nozzle body and is radially provided with the airport being communicated with jet chamber.
Further: gas spray head comprises adjustable cap, adjustable cap coaxially arranges and is threaded with nozzle body, and adjustable cap axial location is corresponding with airport position.
Further: anode-baking furnace flame injection device comprises controller and air valve, on every point of bronchus, be provided with air valve, controller control air valve opens and closes, and it is different that different air valves open and close the moment.
The beneficial effects of the utility model are: natural gas enters jet chamber by fuel gas hole, and natural gas Rapid Flow is crossed jet chamber and made in jet chamber to produce negative pressure, and air enters jet chamber by airport because of the negative pressure in jet chamber, for combustion of natural gas provides sufficient air.By calculating or experimental design airport size, natural gas and air proportioning in combustion process are reached rationally, can make natural gas reach good fired state.
Accompanying drawing explanation:
Fig. 1 is anode-baking furnace structural representation;
Fig. 2 is gas spray head structural representation;
Fig. 3 is each the jet cyclic graph of gas spray head;
In figure, be labeled as: gas spray head 1, point bronchus 2, air valve 3, nozzle body 4, fuel gas hole 5, adjustable cap 6, airport 7, jet chamber 8.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Anode-baking furnace flame injection device comprises at least two gas spray head 1 and point bronchus 2 identical with gas spray head 1 quantity, divide bronchus 2 to be connected with gas spray head 1, as Fig. 2 is, gas spray head 1 comprises nozzle body 4, nozzle body 4 inside are prolonged nozzle body 4 and are axially provided with the fuel gas hole 5 and the jet chamber 8 that are interconnected, and nozzle body 4 inside are prolonged nozzle body 4 and are radially provided with the airport 7 being communicated with jet chamber 8.Natural gas enters jet chamber 8 by fuel gas hole 5, and natural gas Rapid Flow is crossed jet chamber 8 and made the interior generation negative pressure in jet chamber 8, and air enters jet chamber 8 by airport 7 because of the negative pressure in jet chamber 8, for combustion of natural gas provides sufficient air.By calculating or experimental design airport 7 sizes, natural gas and air proportioning in combustion process are reached rationally, can make natural gas reach good fired state, assurance natural gas fully burns, the raising quirk thermal efficiency.
For the ease of the auxiliary air amount that regulates airport 7 to enter, gas spray head 1 comprises adjustable cap 6, and adjustable cap 6 coaxially arranges and is threaded with nozzle body 4, and adjustable cap 6 axial locations are corresponding with airport 7 positions.Turn adjustable cap 6, can regulate adjustable cap 6 to cover the area of airport 7, is in fact equivalent to change airport 7 sizes, can regulate airport 7 to enter the auxiliary air amount in jet chamber, thereby regulate the fired state of natural gas, guarantee that natural gas fully burns, improve the quirk thermal efficiency.
Further, anode-baking furnace flame injection device comprises controller and air valve 3, on every point of bronchus 2, is provided with air valve 3, and controller control air valve 3 opens and closes, and it is different that different air valves 3 open and close the moment.It is different that different air valves 3 open and close the moment, the less and wild effect of each gas spray head 1 gas pressure of avoiding the synchronous opening and closing of each air valve 3 to cause.Each 3 keying cycles of air valve, during Fig. 3 medium wave peak, air valve 3 was opening preferably as shown in Figure 3, and during trough, air valve 3 is closed condition.
