Abstract
The utility model discloses a torch head for discharging and combusting combustible waste gas. The torch head is orderly composed of an intake charge segment 1, a mixing segment 2 and a flame stabilizing and diffusing segment 3 from low to high, wherein, in the intake charge segment, the side of a waste gas spray head is provided with a first air injection passage 5; swirl vanes 7 which are used for homogeneously mixing the combustible waste gas and combustion air are arranged in a flow passage of the mixing segment; a diversion ring, a second air injection passage and a combustion supporting combustion chamber for an outlet of a priming combustible gas spray head are arranged in the flow passage of the flame stabilizing and diffusing segment. Except that the utility model can conveniently and reliably realize ignition under a tower, the utility model can also defend against the extinguishment of combusting flame caused by the flow fluctuation of exhaust emission and the variation of high-altitude wind, and the ability of a combusting torch for resisting the fluctuation of gas flow and resisting the wind is greatly enhanced.
Description
The utility model belongs to the combustible exhaust gas treatment facility and makes the field.
Be used at present combustible exhaust gas is discharged burning fire torch head, the shortcoming that has two aspects, one, because the mode that adopts combustible exhaust gas directly to burn, when the flow because of certain reason combustible exhaust gas takes place bigger variation to occur constantly than great fluctuation process or upper-level winds, easily cause the combustion flame to extinguish, the less stable of burning is easy to cause the accident and air pollution; Its two, prior art generally is to adopt at the bottom of the igniting of flare discharge tower bottom electron is ignited by tower the shop to realize the torch ignition in high-altitude to the combustion gas string fire tube of igniting of cat head, the igniting reliability is relatively poor.
In view of the as above shortcoming of prior art, the purpose of this utility model is a kind of novel combustible exhaust gas discharging of design burning flare tip, makes it to have strong, the flameholding of anti-exhaust gas flow fluctuation ability, the advantage that ignition operation is convenient and reliable.
The purpose of this utility model is to realize by following design.
By the combustible exhaust gas discharging of forming with the ignite gas spray head and the ignition mechanism etc. of the waste gas shower nozzle of exhaust pipe fit and the next-door neighbour's waste gas shower nozzle flare tip that burns, flare tip is made up of air inlet section, mixer and steady flame diffuser three parts from low to high successively, in the air inlet section, the side neighbour of waste gas shower nozzle is equipped with the first air ejection road; Be built-in with at the runner of mixer and be used to make combustible exhaust gas and the mixed uniformly swirl vane of combustion air; In the runner of steady flame diffuser, be provided with the guide ring and the second air ejection road, also be provided with the gas spray head of igniting and export combustion-supporting combustion chamber, the firing tip of ignition place combustion-supporting combustion chamber near.
After adopting structure as above, the combustible exhaust gas with certain flow rate enters the air inlet section by spout, the poor influence that is stressed, and the air of some also enters in the air inlet section by its side neighbour's the first air ejection road.Be subjected to the influence of gas flow rate, the air-flow of mixer is subjected to the blade effect to produce eddy flow, makes combustible exhaust gas and combustion air be able to even mixing.Mixed gas is when entering steady flame diffuser, except that further sneaking into an amount of air of introducing by the second air ejection road, also the influence because of guide ring in the runner forms the air mixture eddy current very favourable to burning, and this combustion gas eddy current flow is initiated burning when igniting the fuel gas buring chamber.Because the entering of air makes combustible exhaust gas well mix flowing through to ignite promptly to produce with air before the fuel gas buring chamber, and the inlet of air becomes certain proportionate relationship with the flow of waste gas, so the changes in flow rate of waste gas is difficult for causing the combustion flame to extinguish, the combustion stability and the anti-exhaust gas flow that have improved flare tip greatly change performance.In addition, the utility model is arranged on electronic ignition device on the flare tip, need not to adopt the igniting of string fire tube, makes the convenient safety of igniting.
Description of drawings is as follows.
Fig. 1 is the vertical view of the utility model embodiment.
Fig. 2 is the A-A longitudinal sectional view of Fig. 1.
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.
Can see that in Fig. 1 He among Fig. 2 whole flare tip is made up of air inlet section 1, mixer 2 and steady flame diffuser 3 three parts from low to high successively, in the air inlet section, the side neighbour of waste gas shower nozzle 4 is equipped with the first air ejection road 5,6 and is the supporting gusset.Be built-in with at the runner of mixer and be used to make combustible exhaust gas and the mixed uniformly swirl vane 7 of combustion air, each swirl vane is fixed on runner inner wall, 8 is swirl vane aiding support muscle, swirl vane generally has an installing angle (this point is similar to the conventional fan blade) in the radial direction of runner, and air-flow is subjected to the water conservancy diversion of swirl vane to become eddy flow.Be provided with the guide ring 13 and the second air ejection road 9 in the runner of steady flame diffuser, guide ring is actually an intilted ring, produces when fluid flows through on its surface to mix eddy flow; Also be provided with ignite gas spray head outlet 10 and combustion-supporting combustion chamber 11 in the runner of steady flame diffuser, the firing tip of ignition 12 place combustion-supporting combustion chamber near, ignition causes ground ignition control by priming supply lead-in wire 14.During igniting, the combustion gas of igniting (being generally natural gas) after igniter 13 igniting, produces constant kindling material source by gas spray head outlet 10 ejections of igniting combustion-supporting combustion chamber 11 in, and the formation of being ignited during through this constant kindling material source of the combustible exhaust gas of discharging is burnt.
For further improving anti-upper-level winds performance of the present utility model, be provided with steady flame on the top of flare tip circle ring 15 takes place, spread all over aperture (being wherein two) on this circle ring as 16 among the figure, 17, when burning, the part combustion gas is enclosed the interior combustibility that forms of influence inflow aperture of ring aperture eddy current and is stablized the steady flame of anti-upper-level winds.
When reality was implemented, on flare tip, igniter, the gas spray head of igniting and combustion-supporting combustion chamber can parallelly be symmetrical arranged two groups (as 18 among figure, 19,20), and the ability of the anti-high-altitude beam wind of flare tip is further strengthened.The shape of combustion-supporting combustion chamber can have multiple variation, is convenient processing and manufacture, is good with half round post generally.
