Background technology
Wet desulfurization of flue gas by limestone-gypsum method technique generally adopts the method for forced oxidation in tower to carry out, object is that the calcium sulfite oxidation that sulfur dioxide and calcium carbonate reaction in slurries generate is become calcium sulfate, the saturated rear formation calcium sulphate dihydrate of calcium sulfate, i.e. gypsum, is convenient to subsequent treatment.Other calcium bases and magnesium basis wet method sulfur removal technology need to add oxidation air forced oxidation equally, just can carry out follow-up processed.
At present, ductwork type forced oxidation air hose is more and more used.But the arrangement of most ductwork type oxidation air pipe, severally has very lacunary oxidation air pipe for stretching into from Ta Bi side.Because desulfurizing tower is cylindrical, the oxidation air pipe stretching into desulfurizing tower is different in size, and therefore pipeline internal gas pressure drag losses is different, causes oxidation air gas distribution uneven.And the pressure head at same oxidation air pipeline each aperture place is also not identical, also impel gas distribution more uneven.
In addition, the solarization air cap on oxidation air pipe is aperture form, and in tower, slurries are suspension, easily block aperture, and oxidation air pipe are arranged in desulfurizing tower inside during employee's misoperation, is not easy to observation and process.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides that a kind of structure is simple, uniform air distribution, the safe and reliable oxidation air pipe network for desulfurizing tower.
The technical solution adopted in the utility model is: a kind of oxidation air pipe network for desulfurizing tower, comprises many horizontal branch pipees and communicating pipe; Described horizontal branch pipe is arranged on desulfurizing tower wall, and the lower disposed of horizontal branch pipe has gas distribution aperture, and one end of horizontal branch pipe was connected with communicating pipe; Described horizontal branch pipe is provided with liquid sealing pipe near being communicated with pipe end, and liquid sealing pipe is positioned at desulfurizing tower wall, vertically arranges, opening down; Described communicating pipe is positioned at outside desulfurizing tower wall.
Above-mentioned in the oxidation air pipe network of desulfurizing tower, the lower disposed of described horizontal branch pipe has many arrangement gas apertures, the gas distribution aperture of often arranging in gas aperture is evenly arranged along the axis direction of horizontal branch pipe, has an acute angle between the axis of gas aperture of often arranging and vertical direction.
State in the oxidation air pipe network of desulfurizing tower, the lower disposed of described horizontal branch pipe has two arrangement gas apertures, and axis and the vertical direction angle of two arrangement gas apertures are 45 °.
Above-mentioned in the oxidation air pipe network of desulfurizing tower, many described horizontal branch pipees be arranged in parallel.
Above-mentioned in the oxidation air pipe network of desulfurizing tower, also comprise many brace summers, many brace summers are installed in parallel on desulfurizing tower wall, support many horizontal branch pipees.
Above-mentioned in the oxidation air pipe network of desulfurizing tower, described brace summer is arranged perpendicular to horizontal branch pipe.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, fabrication and installation convenient; The utility model adopts and makes each arm be connected intercommunication communicating pipe, make oxidation air gas distribution evenly, improve the utilization rate of oxidation air; The axis of gas distribution aperture of the present utility model and vertical direction are 45 ° and arrange, and gas distribution aperture is not easily blocked; Communicating pipe of the present utility model is positioned at outside desulfurizing tower, is convenient to equipment observation and safeguards.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1,3, the utility model comprises many horizontal branch pipees 1, many brace summers 4 and communicating pipe 3; Described many horizontal branch pipees 1 are installed in parallel on desulfurizing tower wall 6, and the lower disposed of horizontal branch pipe 1 has two arrangement gas apertures 5, and the gas distribution aperture of often arranging in gas aperture is evenly arranged along the axis direction of horizontal branch pipe 1.As shown in Figure 2,4, axis and the vertical direction angle of two arrangement gas apertures 5 are 45 ° (two arrange the axis of gas aperture 5 and vertical direction angle also can be other acute angles), one end of horizontal branch pipe 1 was connected with communicating pipe 3, described horizontal branch pipe 1 is provided with liquid sealing pipe 2 near being communicated with 3 pipe ends, liquid sealing pipe 2 is positioned at desulfurizing tower wall 6, vertical setting, opening down.Described communicating pipe 3 is positioned at outside desulfurizing tower wall 6.Described many brace summers 4 are installed in parallel on desulfurizing tower wall 6, and brace summer 4 is arranged perpendicular to horizontal branch pipe 1, for supporting many horizontal branch pipees 1.
Described horizontal branch pipe 1 adopts alloy material or glass steel material with liquid sealing pipe 2.Communicating pipe 3 and horizontal branch pipe 1 adopt Flange joint.Each horizontal branch pipe 1 is barrel forms with desulfurizing tower wall place connected mode, and easy access is safeguarded.Brace summer 4 can be placed in above horizontal branch pipe 1, also can be placed in below horizontal branch pipe 1.
In desulfurizing tower, the quantity of horizontal branch pipe 1 is determined according to desulfurizing tower diameter and gas distribution parameter.Size, the quantity and spacing of gas distribution aperture 5 are mainly determined according to oxidation air amount and gas distribution parameter.In order to reach better gas distribution effect, 45 ° of positions obliquely, the left and right sides, whole horizontal branch pipe 1 bottom, arrange an arrangement gas aperture 5, as shown in Figure 2 and Figure 4 respectively.The length of liquid sealing pipe 2 is determined by oxidation fan pressure head and oxidation air pipe buried depth, and its end is uncovered form, and object is that the operation liquid level in order to adapt to desulfurizing tower changes and repair and maintenance, and when normally running, oxidation air can not spray from liquid sealing pipe 2 open-mouth.
Oxidation air sprays into desulfurization tower slurry pool by gas distribution aperture 5, is calcium sulfate by the calcium sulfite oxidation in slurries.Gas distribution aperture 5 is arranged obliquely, not easily results in blockage.In addition, because gas distribution aperture 5 is evenly arranged, the intercommunication and each horizontal branch pipe 1 is connected by communicating pipe 3, controls the air loss of each horizontal branch pipe 1, oxidation air is distributed in slurries more even, improve the utilization rate of oxidation air.Meanwhile, communicating pipe 3 is positioned at outside desulfurizing tower, and be convenient to equipment observation and safeguard, the material being also beneficial to communicating pipe is selected.
The above example is for illustration of the utility model; though be described by technical term in literary composition; but do not limit protection domain of the present utility model with this; every spirit according to this patent and principle, to its any equivalent modifications done and replacement, all should be included in protection domain of the present utility model.
