Landfill gas torch flow regulator of the present utility model, during use, can closeouts seal the part gas outlet as required, change existing torch gas outlet quantity, increaser is installed on remaining gas outlet, the horn mouth shape of increaser designs, and effectively reduces the atmospheric pressure that of landfill gas, increases landfill gas and Air mixing degree.For abundant mixing, can also on horn mouth, offer a plurality of air inlets.
By above-mentioned technical scheme, the utility model possesses following technique effect:
1, landfill gas torch flow regulator of the present utility model, occluding member gas outlet according to actual needs, methane is concentrated on place, the gas outlet burning that is arranged with increaser, amplified the combustion space of landfill gas, reduced and atmospheric pressure, improved the methane relative concentration, the design of trumpet type increaser has improved the mixability of air and methane, and then has improved ignition success rate;
2, landfill gas torch adjusting device of the present utility model, the loudspeaker bore direction on increaser top is offered breach, is convenient to the mounting points picker bar more.Can also be at affixed relatively two the hollow small cylinders of closeouts or increaser bottom, the cylinder top seal is welded suspension rod on two little hollow circular cylinders, and the suspension rod below is welded with hold-down nut, by suspension rod closeouts and increaser are fixed in the below of landfill gas combustion head, make installation more firm;
3, landfill gas torch adjusting device of the present utility model, a plurality of air inlets are set on the increaser, improved the cross-ventilation in the combustion space, improved the Flow-rate adjustment ratio, for force environment has been created in burning, improved the combustion stability of low discharge torch, improved the burn-off rate of torch, reduced the combustible component content requirement of torch monomer landfill gas;
4, landfill gas torch flow regulator of the present utility model is reasonable in design, simple in structure, easy for installation, and simple and convenient operation and maintenance has the good social economic worth.
Description of drawings
Fig. 1 is the structural representation of existing landfill yard open type landfill gas torch burning head;
Fig. 2 is the structural representation of landfill gas torch flow regulator;
Fig. 3 is the closeouts structural representation of landfill gas torch flow regulator;
Fig. 4 is the increaser structural representation of landfill gas torch flow regulator.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing 2-4.
Referring to shown in Figure 2, a kind of landfill gas torch flow regulator, it is made up of three closeouts 1 and an increaser 2; Closeouts 1 blocks three gas outlets of torch burning head; Increaser 2 flares, bottom 22 is a hollow circular cylinder, is set on another gas outlet.Offer a plurality of air inlets 211 on the horn mouth 21 on increaser 2 tops.Thereby the burning of landfill gas is concentrated on increaser 2 places, the flaring combustion space of having amplified landfill gas that is provided with, reduced and atmospheric pressure, improved the concentration of methane relatively, make itself and air mixability height, and then improved Flow-rate adjustment ratio and ignition success rate, make the burning of low discharge torch more stable.
Referring to shown in Figure 3, closeouts 1 is made up of the hollow circular cylinder 11/12/13 of three top seals that are connected in parallel, and cylinder 11 diameters at middle part are greater than the cylinder 12/13 at two ends, and middle part cylinder 11 is set on the combustion head gas outlet.Weld suspension rod on two little hollow circular cylinders 12/13 of both sides, the suspension rod below is welded with hold-down nut, and a bolt passes hold-down nut suspension rod is fixedly installed on the low bottom-disc of landfill gas torch burning head.
Simultaneously also can be at two little hollow circular cylinders 221/222 of 22 places, bottom of increaser 2 welding, same welding suspension rod on it, suspension rod below welding hold-down nut is fixedly installed in increaser 2 by suspension rod on the low bottom-disc of combustion head (embodying among the figure), thereby makes installation more firm.
Referring to shown in Figure 4, the bell-mouthed air inlet 211 in increaser 2 tops is 2 layers of arrangement, is separately positioned on the circumference with horn mouth concentric different-diameter, and air inlet 211 is an arc-shaped slot.Simultaneously upwards also can offer a breach 212, so that the mounting points picker bar in bell-mouthed footpath.Bell-mouthed design has increased the gaseous exchange in the combustion space, for burning creates an enabling environment, thereby the torch monomer is reduced to the requirement of landfill gas combustible component content.
Certainly, also can increaser 2 and closeouts 1 be fixedly mounted on the combustion head by clip; Screw thread perhaps is set on combustion head, increaser 2 and closeouts 1 are screwed onto on the burning gas outlet.
During actual the use, operating personnel can adjust the quantity of using closeouts and increaser fully as required voluntarily.
The above is preferred embodiment of the present utility model only, is not that the utility model is done any pro forma qualification.Any change that is equal to, modification or differentiation etc. that all those skilled in the art utilize the technical solution of the utility model that the foregoing description is made all still belong in the scope of the technical solution of the utility model.
