Description

The high-speed gas burner

The utility model relates to a kind of high-speed gas burner that is used on the oil-field brine blind roaster.

Existing " partly giving mixed gas firing chews ", number of patent application is 94221011.5, also being used for the oil field water jacket is jealous of, it is chewed, is burnt and chew brick and form by gas inlet tube, primary air system, induction tunnel, secondary air system, burning, weak point is: main air intake is a cover shape, the air quantity size that enters induction tunnel determines that by the forward and backward position of damper this air door enters the deficiency in draught of induction tunnel, mixes inhomogeneous with combustion gas; Cross nozzle has straight hole, and the gas that enters induction tunnel can not form eddy current, gives mixing not reaching specification requirement; What secondary air register was opened is elongated hole, and air intake is inhomogeneous, can not adjust the air quantity size; Former burner is not installed type fire-fighting protection device, particularly winter and is easily put out a fire and be difficult for being found, and is unfavorable for safety in production.

The purpose of this utility model is to avoid the weak point of above-mentioned prior art and a kind of high-speed gas burner is provided.

The useful novel purpose of this reality can reach by following measure: change into existing burner first and second wind system air intake mode adjustable.Increased the main air intake plate washer, it is fixed with nut in the end of main air intake, and main air intake and main air intake plate washer all are drilled with uniform small pores; Cross nozzle is drilled with inclined hole; Secondary air register is taper, forms by inside and outside two layers, and ring flange has the secondary air register plate washer outward, both use bolting, are drilled with uniform hole on ring flange and the plate washer, when loose bolts, plate washer is rotatable, and the secondary air register internal layer has uniform circular hole, and the outer internal layer relatively of secondary air register can horizontally slip.

The purpose of this utility model can also reach by following measure:

This burner is equipped with type fire-fighting protection device, and this device comprises primary element and warning device, and both connect with lead, and primary element is photosensitive probe, is installed on the secondary air register plate washer that warning device is installed in the control room.

This utility model compared with prior art has the following advantages:

Because first and second wind system air intake mode is adjustable, after primary air system makes air and combustion gas is mixed, from cross nozzle inclined hole, spray, make the gas of ejection can form eddy current, combustion gas is fully mixed, is spread with air before helping catching fire, and it is stable, rapid to make it to catch fire; The secondary air register system can regulate air quantity with rotation plate washer or upper and lower mobile skin, makes air intake evenly help fuel gas and fully burns, and has improved efficiency of combustion, thermal power and the thermal efficiency; This burner has low, the safe and reliable advantage of noise simultaneously.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a high-speed gas burner structure schematic diagram;

Fig. 2 is the main air intake schematic diagram;

Fig. 3 is a cross pattern nozzle schematic diagram;

The utility model is described in further detail below in conjunction with accompanying drawing.

The high-speed gas burner comprises gas inlet tube 1, first and second wind system, injector 9, burns and chew system, type fire-fighting protection device etc.

Primary air system comprises pipeline section 2, mounting flange 3, bolt 4, main air intake plate washer 5, main air intake 6, cross nozzle 7, mounting flange 8;

Secondary air system comprises secondary air register skin 10, secondary air register internal layer 11, secondary air register flange 12, ring flange 17, secondary air register baffle plate 18;

The burning system of chewing comprises: burn and to chew brick flange 13, burn and chew 14, nut 15, burn and chew brick 16;

Type fire-fighting protection device comprises: primary element 19 and warning device.

Gas inlet tube 1 and pipeline section 2 welding, mounting flange 3 and pipeline section 2 screwed connections, mounting flange 8 and the welding of injector 9 entrance points, mounting flange (3,8) connects with bolt, pipeline section 2 and cross nozzle 7, main air intake 6 screwed connections, main air intake 6 atresias in the prior art, by the left and right mobile adjusting air quantity of main air intake, the utility model has increased main air intake plate washer 5, and it is fixed in the main air intake end with nut, and is drilled with uniform aperture on plate washer; As shown in Figure 2, main air intake 6 is drilled with 6 apertures, nut is unclamped, rotatable main air intake plate washer 5 is regulated the air quantity of a wind, air quantity was for maximum when the aperture of air door and plate washer aligned, and as shown in Figure 3, cross nozzle 7 prior arts are that straight hole now changes inclined hole into, this can make the gas that enters induction tunnel 9 form eddy current, helps gas combustion.

Secondary air register is taper, by interior, outer two layers of composition, secondary air register internal layer 11 has elongated hole in the prior art, secondary air register internal layer 11 of the present utility model, have uniform 60 circular holes, as air vent, and secondary air register skin 10 can be left with respect to internal layer, right slip quantity-adjustable size, air quantity is big more more at least for the air vent that the outer shelves of turning left are more lived, and helps the burning of combustion gas, and secondary air register plate washer 18 is arranged outside the ring flange 17, both use bolting, be drilled with uniform hole on ring flange 17 and the plate washer 18, plate washer 18 is rotatable during loose bolts, is used for regulating the air quantity of secondary wind.Nut 15 and induction tunnel 9 welding burn and chew 14 and link to each other with nut 15 screw threads, and there is a macropore at the burning center of chewing, two row's apertures are arranged on the inclined-plane, burning is chewed brick 16 and is welded in to burn and chews on the brick flange 13, burns the flange bolting of chewing on brick flange 13 and the water jacket furnace, and burning is chewed in the brick 16 and is lined with flame-proof thermal insulation material.

Primary element 19 in the type fire-fighting protection device is connected by lead with warning device, and primary element is a photosensitive probe, is installed on the secondary wind plate washer 18, and warning device is installed in the control room.

During use, fuel gas enters pipeline section 2 by cross nozzle 7, ejection rotation high velocity fuel gas by gas inlet tube 1, and mix with air that certain ratio falls, adjust the primary air flow size, combustion gas and air are introduced section and be mixed to diffuser in mixers and spread through injector 9 ends, chewing 14 through burning sprays in water jacket is jealous of, by being jealous of negative pressure in the thorax, suck air through the secondary air register system, make gas combustion, make water jacket be jealous of interior water temperature to raise, make the interior crude oil of oil pipe be convenient to flow and carry.
