Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing.
Such as Fig. 1, a kind of adjustable submerged combustion bubbling pipe suit, including mounting flange 1, combustion barrel 2, collapsible tube 3, horizontal cigarette
Pipe 4, upper smoke tube 5, flexibility block water curved 6, lower smoke tube 7, bubbling pipe positioning port 8, bubbling pipe 9, bubble holes 10, discharge opening 11, support
12nd, level governor 13, refractory protection cover 14, heat exchange tank 42.Bubble holes 10 are arranged on the upper end of bubbling pipe 9 and roused for flue gas
Bubble.Block water curved 6, lower smoke tube 7, bubbling pipe 9 of combustion barrel 2, collapsible tube 3, horizontal smoke tube 4, upper smoke tube 5, flexibility is sequentially connected, and is pacified
In heat exchange tank 42.Bubbling pipe 9 is located at the top of combustion barrel 2.Combustor 41 is connected with combustion barrel 2 by mounting flange 1.
Water filling forms cooling bath in heat exchange tank 42.
Such as Fig. 2, combustor 41 is positioned at the heat exchange exterior bottom of tank 42, high-temperature flue gas rate caused by combustor burning natural gas
The combustion barrel 2 being connected with combustor 41 is introduced into, then passes sequentially through collapsible tube 3, horizontal smoke tube 4, upper smoke tube 5, flexible resistance
Water pipe 6, lower smoke tube 7, final high-temperature flue gas bubble 46 spray in the bubble holes 10 of bubbling pipe 9, and high-temperature flue gas is exchanging heat with water-bath
Air water heat exchange is carried out in tank 42, institute's heat exchange amount further passes to heated work by the heat exchange coil 45 to exchange heat in tank 42
Matter is taken away, and the low-temperature flue gas after exchanging heat discharges tank by chimney 43, and the condensed water in low-temperature flue gas passes through the row of overfall 44
Go out the tank that exchanges heat, to keep water level constant.
Mounting flange 1 and the junction of combustion barrel 2 are provided with a discharge opening 11, such as Fig. 3, are specially drawn by combustion barrel 2
Tapping pipe 22, it is connected to by mounting flange outside heat exchange tank, an aciculiform drain valve 23 is installed in discharge opening end, for manual
Accidental factor suck-back is discharged into the ponding in combustion barrel.
Pre-buried fixing bolt 21 is fixed as one by welding manner and mounting flange 1, and ensures that sealing is held with certain
Pressure.Mounting flange 1 and pre-buried fixing bolt 21 are used to be connected with the combustor 41 outside tank.The natural gas and sky mixed
Gas directly can be burnt in combustion barrel 2, and combustion barrel 2 is completely submerged in water, it is no longer necessary to which cooling water system cools down to it.
Smoke pipe is designed as shape of chinese word Ji, and highest point is that the flexibility for being higher by liquid level certain altitude blocks water curved 6, when combustor 41 is shut down
Afterwards, to stop that the aqueous reflux in tank enters combustion barrel.Due to blocking water, curved be not fully immersed in water cools down, and blocks water curved above
Refractory protection cover 14 is set, the heat exchange of high-temperature flue gas and tank inner air in pipeline is prevented, causes water groove upper cap temperature too high
With the rise of exhaust gas temperature, the heat exchange efficiency of flue gas is improved.
Level governor 13 is set between upper smoke tube and lower smoke tube, for adjusting being horizontally mounted for bubbling pipe, it is ensured that high
Warm flue gas can be bloated uniformly.Such as Fig. 4, level governor 13 includes the telescopic tube that two is respectively plus thread and left-hand thread
31, and the connector 32,33 with plus thread and left-hand thread respectively.In actual motion, due to place and mounting condition is processed
Limitation, can not ensure the fully horizontal of equipment bottom surface sometimes, and causing the bubbling of bubbling pipe 9, uneven (part bubble holes can bloat
Flue gas, other bubble holes do not have flue gas bulging) appearance of situation, now need to adjust level governor 13, according to bubbling pipe 9
Inclined degree or bubbling situation, the connector 32,33 with plus thread and left-hand thread is suitably adjusted, so as to adjust bubbling shop 9
Levelness, it is ensured that high-temperature flue gas can be bloated uniformly.
Such as Fig. 5, bubbling pipe positioning port 8 and bubbling pipe 9 are connected through a screw thread, and fixed by positioning jackscrew 81, just
In the bubbling pipe for changing different perforate sizes, quantity, pitch of holes, realize complete negative under Different field mounting condition and combustion conditions
Uniform bubbling in the range of lotus.In actual motion, when submergence (liquid level of water-bath in tank) changes, for height
The pressure requirements of warm flue gas also change therewith；When burning load changes, exhaust gas volumn caused by burning also changes therewith；Pressure
Fluctuation with exhaust gas volumn can all have an impact to the uniformity of bubbling, now need to change the bubbling pipe 9 of different size.According to reality
Border situation, by adjusting perforate size, quantity, the pitch of holes of bubbling pipe 9, design the bubbling pipe 9 of different size.
Such as Fig. 6, bubbling pipe suit sets two supports 12, and one is arranged on bubbling pipe and combustion barrel, another installation
At the lower exit bend of horizontal smoke tube and lower smoke tube, support longitudinally uses screw thread standpipe 91, respectively by top nut 92 with
Nut 93 adjusts support plate height, passes through ground by upper supporting plate 94 and the fixed combustion cylinder of lower carrier plate 95 or bubbling pipe, support respectively
Pin positioning hole 96 is connected with tank bottom plate, to ensure the firm of whole bubbling pipe suit.
In addition to the refractory material in refractory protection cover, all material is made from Stainless steel 316 L.It is main in high-temperature flue gas
Composition is nitrogen oxides, and chemical reaction, which occurs, with water by air water heat exchange produces acidic materials, makes the water in tank that weak acid be presented
Property, there is corrosivity.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement
The scope of protection of the utility model is also should be regarded as with retouching.
