A kind of self-priming Dust removal chimney of oil field boiler

Technical field

The utility model belongs to field of environment protection equipment, the in particular to self-priming Dust removal chimney of the oil field boiler of energy-saving and emission-reduction.

Background technique

Global warming becomes the topic of people's care, the low-carbon economy based on low energy consumption, low pollution increasingly Become global hot spot simultaneously.The essence of low-carbon economy is development of clean energy, high efficiency of energy utilization, pursues Green GDP, and core is Energy technology and emission-reduction technology innovation, existing oil field boiler chimney is largely direct emission, not only causes energy waste, and And pollution air environment, it is therefore desirable to which one kind can be by the chimney of flue dust and air separation.

Utility model content

For overcome the deficiencies in the prior art, the utility model provides a kind of self-priming Dust removal chimney of oil field boiler.

The technical solution of the utility model is: a kind of self-priming Dust removal chimney of oil field boiler, including cylindric outer cylinder, described Outer tube inner wall is connected with flight, and the flight internal diameter is connected with hollow inner prop, and the outer cylinder bottom end is connected with bottom plate, described There are four being open in the circumferential direction, the opening is connected with support column, at least one setting of the support column for setting in bottom plate For dust fall pipe, the outer cylinder top is connected with hollow round table shape taper cylinder, is connected with heightened column on the taper cylinder rotary table osculum, Rain cap is welded at the top of the heightened column.

The dust fall pipe, which is connected with, draws dirt pipe.

The dust fall pipe and the dirt pipe connection type of drawing is welding.

The dust fall pipe, which is open described in welding at liftoff 1-2 rice, draws dirt pipe.

The dirt pipe that draws introduces disposal box obliquely.

The top drawn dirt pipe and be welded on the disposal box obliquely.

The flight section is triangle.

The flight outer is welded on outer tube inner wall, and internal diameter is welded on inner prop, internal diameter along the inner prop spiral to On.

The utility model has the beneficial effects that: comparing traditional direct flue gas emission, oil field boiler self-priming of the invention Formula Dust removal chimney, low manufacture cost, installing easy to operate, flexible operation greatly reduced the row of flue dust in use It puts, improves gas cleaning effect, and recycling and reusing, the efficient economizing energy are carried out to smoke discharging residual heat.

In figure, 1. rain caps, 2. heightened columns, 3. taper cylinders, 4. outer cylinders, 5. inner props, 6. support columns, 7. disposal boxes, 8. spirals Piece, 9. bottom plates, 10. dust fall pipes, 11. draw dirt pipe.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and detailed description.

The utility model provides a kind of self-priming Dust removal chimney of oil field boiler, and structure is as shown in Figure 1, include cylindric outer Cylinder, the outer tube inner wall are connected with flight, and the flight internal diameter is connected with hollow inner prop, and the outer cylinder bottom end is connected with bottom Plate, for the interior setting of the bottom plate there are four being open in the circumferential direction, the opening is connected with support column, the support column at least one A to be set as dust fall pipe, the outer cylinder top is connected with hollow round table shape taper cylinder, is connected on the taper cylinder rotary table osculum Rain cap is welded at heightened column, the heightened column top.

Embodiment 1

Chimney is formed by inner prop 5, flight 8,4 welding production of outer cylinder, and top heightened column 2, heightened column 2 is determined by boiler suction Fixed height.Inner prop 5 is by 7 meters of a root longCasing is rolled with steel plate.Flight 8 with h=3mm steel plate cut system and At the wide 550mm of piece.Outer diameter D 1500mm, internal diameter=400mm.8 internal diameter of flight along inner prop spiral and upper welding, outside flight 8 Edge is welded on 4 inner wall of outer cylinder.Outer cylinder 4 is rolled by h=4mm steel plate, is highly 7 meters with inner prop 5.Bottom plate 9 uses h= 10mm, long x wide are that 1600mmx1600mm steel plate is laid at the top of boiler room, and four mouths are diametrically uniformly opened in 1500mm line, Roof cover board is similarly open so as to perforating branches dagger 6.6 bottom of support column is placed in room on Horizon, is highly Horizon to roof 10mm steel plate surface adds 2~3mm, upper orifice and the welding of 10mm steel plate.Having one in four support columns is dust fall pipe 10, dust fall Flat 1~2 meter of place opening that pipe 10 is liftoff, which is welded, draws dirt pipe 11, draws dirt pipe 11 and introduces at the top of disposal box 7 obliquely and welds.In deduster Taper cylinder 3 is welded at top, 2 meters of height, and big mouth and outer cylinder are with thick, and osculum and heightened column 2 are the same as being slightly 800mm.It is welded at the top of heightened column 2 Connect rain cap 1.

The present invention is based on four eight tons of vertical boilers to be transformed, and is returned the flue dust of high temperature using the centrifugal force of helical blade remaining Hot stove, to realize that smoke discharging residual heat carries out recycling and reusing, the effect of the efficient economizing energy.

The above, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is simultaneously Not limited to this, all those familiar with the art are in technical scope disclosed by the utility model, according to this reality Being subject to equivalent substitution or change with the design of novel technical solution and its utility model should all cover in the utility model Within protection scope.
