Abstract
The utility model provides a kind of high velocity air burner apparatus, comprise flame gas blowout mouth, mixing chamber, and be connected to the gas pipeline and air duct that mixing chamber one end part is set up, it is characterized in that described gas pipeline latus rectum is at least 4 times of described air duct latus rectum, and described flame gas blowout mouth becomes pyramid type, be fixedly connected with described mixing chamber the other end, and be connected with gaseous mixture pipeline and burning torch at described flame gas blowout mouth sidepiece.And be staggered up and down in described mixing chamber deflector is set.Thus solve combustion gas and air mixing velocity that conventional burners occurs slowly, mix uneven, combustion heat energy utilization rate is low, and very easily occurs the problem of circuit fire phenomenon after accelerating simulation model for mixing gases flows speed.
Description
Technical field
The utility model relates to metal plate and belt deep processing heating art, particularly relates to the burner in metal plate and belt continuous hot galvanizing, hot-dip aluminizing, metal plate and belt or plating solution being carried out to open firing.
Background technology
At present, conventional metals strip field of deep, the general natural gas that adopts heats strip, but because natural gas and air are difficult to mix at short notice in the cavity of burner, just carry out ignition, therefore waste a large amount of natural gas energy resources, heat utilization rate is extremely low.And by the jet velocity of increase air and natural gas, accelerate the flow-disturbing speed of gas in mixing chamber, finally realize natural gas and the rapid mixing of air in cavity, but this kind of way is due to the quickening of combustion gas velocity, be easy to occur circuit fire phenomenon, cause the instantaneous extinguishing of flame sprayed, the requirement temperature of metal plate and belt cannot be reached, not only cause the waste of natural gas energy resource, also result in metal plate and belt and cannot reach requirement temperature, and occur follow-up zinc-plated, aluminizing there are serious quality problems.
Utility model content
In order to the combustion gas and air mixing velocity that solve the appearance of above-mentioned conventional burners are slow, mix uneven, combustion heat energy utilization rate is low, and after accelerating disturbance velocity, very easily there is the problem of circuit fire phenomenon, the invention provides a kind of novel high velocity air burner apparatus, comprise flame gas blowout mouth, mixing chamber, and be connected to the gas pipeline and air duct that mixing chamber one end part is set up, it is characterized in that described gas pipeline latus rectum is at least 4 times of described air duct latus rectum, and described flame gas blowout mouth becomes pyramid type, be fixedly connected with described mixing chamber the other end, and be connected with gaseous mixture pipeline and burning torch at described flame gas blowout mouth sidepiece.And be staggered up and down in described mixing chamber and deflector is set.
By reducing the latus rectum of air duct, the pressure of increase air in pipeline, further quickening air is ejected into the speed in mixing chamber from air duct, thus the flow-disturbing speed of empty combustion gas in quickening cavity, and by being staggered up and down in mixing chamber, deflector is set, increase air and the time of contact of combustion gas in mixing chamber, and guide the spiral air flow formed in mixing chamber, further the mixing velocity of quickening air and natural gas.
Certainly, in order to solve the flow perturbation circuit fire phenomenon occurred soon, inventor have employed at flame gas blowout mouth arranged outside gaseous mixture pipeline and burning torch.By arranging gaseous mixture pipeline near flame gas blowout mouth flame jet, the natural gas mixed in advance and air are transported in spout, by burning torch ignition, make flame gas blowout mouth sidepiece have naked light to burn all the time, and be transported to the gaseous mixture of natural gas in spout and air by deflector, due to the quickening of its jet velocity, after naked light is lighted, its flame sprays from spout, which solves, the problem of the circuit fire phenomenon that flow-disturbing speed is accelerated and occurred.
Meanwhile, preferably, described gas pipeline is connected with mixing chamber by installing plate with air duct.
Preferably, described air duct connects heat exchanger and air compression plant.
Be transported to flow in mixing chamber and flow velocity to better control air, air duct is connected with the checkout equipment such as compression set and flowmeter.Certainly in order to prevent flame gas nozzle from occurring circuit fire phenomenon further, adopting the operation being transported to the air in mixing chamber and heating through heat exchanger, to improve the temperature before mist burning, improving the thermal efficiency, improving energy utilization rate.
Accompanying drawing explanation
The structural representation of the high velocity air burner that Fig. 1 provides for the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1, the high velocity air burner that the utility model provides, comprise mixing chamber 1, and be connected to air duct 2 and the gas pipeline 3 of mixing chamber 1 one end, and be fixedly connected with at the other end of mixing chamber 1 and be provided with conical flame gas blowout mouth 4, connect gaseous mixture pipeline 5 and burning torch 6 at the sidepiece of described flame gas blowout mouth 4, and be staggered up and down in mixing chamber 1 deflector 7 is set.Air duct 2 is connected with mixing chamber 1 by installing plate 8 with gas pipeline 3, and the latus rectum of gas pipeline 3 is 4 times of air duct 2 latus rectum, combustion air is by the air duct 2 of less latus rectum, fully serve the effect accelerating speed air flow, and, in order to improve air pressure further, gas flow rates in further quickening mixing chamber 1, air duct 2 is provided with air compression plant 9 and heat exchanger 10, heat exchanger 10 can be in extreme conditions, combustion air is heated, mist in further intensification mixing chamber 1, reach the lifting that mist lights front temperature, while improving efficiency of combustion, avoid because mist temperature is too low, and the circuit fire phenomenon that appearance is lighted a fire not.
By blower fan, combustion air is sent in mixing chamber 1 from air duct 2, and can be under extreme conditions, open compression set 9 and heat exchanger 10 that air duct 2 is arranged, speed air flow and combustion air temperature can be accelerated further, simultaneously, natural gas is transported in mixing chamber 1 by gas pipeline 3 equally, combustion air and natural gas mix in mixing chamber 1, and under the guiding of the deflector 7 arranged that is staggered up and down in mixing chamber 1, natural gas and combustion air fully mix and move ahead in cavity, final at flame gas blowout mouth 4 place, ignition is carried out by burning torch 6, flame gas sprays from spout, treat metal heating plate band to heat, and for preventing, gaseous mixture flow velocity is too fast there is circuit fire phenomenon, at spout 4, place is provided with gaseous mixture pipeline 5, spout 4 place is transported to by the natural gas mixed in advance and air, under burning torch 6 acts on, form naked light, can the object of very first time ignition to reach gaseous mixture that spout 4 ejects.
Above-mentioned is only general principle of the present utility model, any restriction not made the utility model, every according to the utility model to its equivalent variations of carrying out and modification, all within protection domain of the present utility model.
