Description
Technical field
The present invention relates to desulfurization fountain absorption tower accessory, be specifically related to utilize potential energy to promote the tower external oxidation playpipe of slurries oxidizing process.
Background technology
Desulfuration absorbing tower is to use physics and chemical method, removes sulfur dioxide in flue gas (SO
2) device or structures.
In multiple desulfuration absorbing tower; It is the fountain absorption tower that one type of absorption tower is arranged; Its groundwork process is to utilize slurry circulating pump will absorb slurries to be transported to the spraying layer that is made up of a plurality of nozzles; Form intensive atomization slurry spray district after absorbing the atomizer ejection of slurries by spraying layer, slurries contact with flue gas in the atomizing spray district, absorb the SO in the flue gas in contact process
2Deng pernicious gas, accomplish flue gas desulfurization, slurries descend slowly and lightly in the stock tank of bottom, absorption tower along inside, absorption tower.
Desulfurization is also claimed oxidation air with oxidation wind, is the oxidation air that equipment such as oxidation fan provide is transported in the pressure absorption tower slurries, for slurries provide oxygen, with the SO in the slurries
2, H
2SO
3, SO
3 2-Deng being oxidized to SO
4 2-And with slurries in Ca
2+Reaction forms CaSO

2O.
The oxidation air source of the gas has various ways, but mainly is the conveying that relies on external driver device to provide power to carry out oxidation air, has the shortcoming of high, the not enough energy-conserving and environment-protective of complex structure, construction costs and maintenance cost.
Summary of the invention
Technical problem to be solved by this invention is: the purpose of this invention is to provide a kind of simple in structure, low low a kind of desulfuration absorbing tower oxidation playpipe of maintenance cost that reaches of cost.
Technical solution of the present invention is: it comprises the decline accelerating tube and mixes anemostat; Tube wall is provided with air-breathing acceleration hole to the decline accelerating tube in the lower end; The outer wall that the periphery of decline accelerating tube in place, air-breathing acceleration hole is with splashproof pipeline section and decline accelerating tube forms annular space; The upper end of splashproof pipeline section is uncovered and be higher than air-breathing acceleration hole, and the lower end of splashproof pipeline section is connected with decline accelerating tube outer wall, mixes anemostat and is connected decline accelerating tube lower end.
Technique effect of the present invention is: it has simple in structure, the low low advantage of maintenance cost that reaches of cost, and is specific as follows:
1, can be used to replace oxidation fan and perhaps reduce exerting oneself of oxidation fan, reach energy-conservation effect.
2, air-breathing acceleration hole inhaled air fully mixing in mixing anemostat, mixed slurry reflux is to the bottom, absorption tower, and flow process has increased by one times, has increased the time of contact of oxidation air and slurries, has improved the utilization rate of oxidation air.
3, the slurries pH value that is used to spray is lower, helps the slurries oxidation.
4, mix anemostat and can guarantee that slurry reflux has higher flow velocity when getting into the absorption tower if adopt the caliber identical with air-breathing acceleration hole.Guarantee that slurry stream has higher kinetic energy.
5, the function that there is automatic adjusting inspiratory capacity the air-breathing conciliation of air intake duct chamber is quickened in the decline of desulfuration absorbing tower high potential energy slurries, guarantees that operation is smooth and easy.
6, can adjust the oxidation air amount through the air inflow in the air-breathing acceleration of adjustment absorption tower high potential energy slurries decline accelerating tube hole, it is too high can not cause exporting the oxygen amount.
Description of drawings
Fig. 1 is a sectional structure chart of the present invention;
Fig. 2 is an assembly structure sketch map of the present invention.
The specific embodiment
Among Fig. 1, former smoke inlet 5, clean exhanst gas outlet 6, slurries gathering system 7, spray system 8.
As illustrated in fig. 1 and 2; It comprises decline accelerating tube 1 and mixes anemostat 2; Tube wall is provided with air-breathing acceleration hole 3 to decline accelerating tube 1 in the lower end, and the outer wall that the periphery of decline accelerating tube 1 in 3 places, air-breathing acceleration hole is with splashproof pipeline section 4 and decline accelerating tube 1 forms annular space, and the upper end of splashproof pipeline section 4 is uncovered and be higher than air-breathing acceleration hole 3; The lower end of splashproof pipeline section 4 is connected with decline accelerating tube 1 outer wall, mixes anemostat 2 and is connected decline accelerating tube 1 lower end.The annular space that splashproof pipeline section 4 and decline accelerating tube 1 surround has air-breathing conciliation and prevents the slurries function of splashing.
Said decline accelerating tube 1 lower end outwards is the bell mouth shape expansion.
Said air-breathing acceleration hole 3 is axial long shape hole.。
Said air-breathing acceleration hole 3 is long ellipse hole.Also can adopt the slotted hole of other form
The lower port of decline accelerating tube 1 in 3 places, air-breathing acceleration hole and with mix anemostat 2 connections and all adopt the two-phase alloys steel plate of wear resistant corrosion resistant to process.Mixing anemostat 2 can adopt and the identical pipeline of accelerating tube 1 caliber that descends.
The concise and to the point process of the external oxidation playpipe of desulfuration absorbing tower slurries work during operation:
1,1 reception of decline accelerating tube is from the slurries of slurries gathering system 7 slurries absorption cells; Slurries progressively quicken in the decline process; Through air-breathing acceleration hole 3 time; Suck the part air, slurries quicken (the acceleration here is near acceleration of gravity) rapidly, and slurries and AIR MIXTURES are back to the absorption tower through mix anemostat 2.
2, be back to the inner bigger bubble in absorption tower, under the effect of slurry stream, be sheared and form tiny bubble, tiny bubble is inner the rising on the absorption tower, accomplishes further oxidation.
