Abstract
The invention relates to a desulfurization absorption tower with a spraying area taking the shape of an inverted cone frustum. The desulfurization absorption tower comprises a spraying type desulfurization absorption tower body (1), wherein a 2-3-layer spraying area (11) at the lowermost part in the tower body (1) takes the shape of an inverted cone frustum with the sectional area gradually increased from bottom to top and can prevent flue gas from escaping and slurry liquid from directly floating into a slurry tank (12) so as to be helpful for slurry liquid recycling. The desulfurization absorption tower has the advantages that flue gas escaping cannot occur, and the slurry liquid cannot directly float into the slurry tank so as to be helpful for slurry liquid collection and utilization. Under the same working conditions, the desulfurization absorption tower can save energy by 15-25% compared with a conventional absorption tower. In high-load operation, the flue gas flow rate descends from bottom to top, and the slurry liquid is not easy to carry due to relatively low flue gas flow rate at the upper part so as to reduce the load of a demister and be beneficial to the reduction of the carrying quantity of dust such as gypsum in clean flue gas.
Description
Technical field
The present invention relates to smoke eliminator, be specifically related to a kind of spray type desulphurization absorption tower.
Background technology
The absorption tower is a kind of device or structures that utilize physics or chemical method that certain composition in the gas is caught or absorbed.Desulfuration absorbing tower is to utilize physics and chemical method to remove sulfur dioxide in flue gas (SO
2) device or structures.A kind of fountain absorption tower is arranged in the desulfuration absorbing tower; 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, and slurries 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 desulfuration absorbing tower bottom along inside, absorption tower.The slurries spray of existing desulfuration absorbing tower is distinguished and is straight tubular, and flue gas takes place easily for the catch tray of below, slurries spray district and the gap between the desulfuration absorbing tower tower wall escapes, and also has the part slurries and directly descends slowly and lightly in stock tank, is unfavorable for that the slurries collection utilizes.
Summary of the invention
The purpose of this invention is to provide a kind of flue gas that can not take place and escape, do not have the desulfuration absorbing tower that slurries directly descend slowly and lightly in stock tank, help slurries collection utilization with rounding taper type spray district.
Technical solution of the present invention is: it comprises spray type desulphurization absorption tower body of the tower, and 2～3 layers of spray district of foot become big from bottom to top gradually, can prevent that flue gas from escaping and slurries directly descend slowly and lightly in stock tank, help the rounding taper type that slurries are recycled for sectional area in the body of the tower.
Technique effect of the present invention is: it has, and the flue gas escape can not take place, and does not have slurries and directly descends slowly and lightly in stock tank, helps slurries and collects the advantage of utilizing, and can also prevent the flue gas bias current.
Compare with existing spray type desulphurization absorption tower, it has following advantage:
1, the less end opening in the regional bottom of spray can be gathered slurries, helps slurries and collects utilization;
2, from the bottom to top gradually long-pending the and spray area of increased cross-section help realizing energy-saving run, when particularly the absorption tower load is low, can be than the energy-conservation 20-35% in traditional fountain absorption tower;
3, flue gas flow rate is slack-off by soon from the bottom to top when heavy-duty service, and bottom flue gas faster can hold up the slurries that part descends slowly and lightly downwards, and slurry drops is " boiling " state in truncated cone spray district, helps the absorption of slurries to sulfur dioxide in flue gas;
4, can reduce " liquid-gas ratio ", realize energy-saving run;
5, when heavy-duty service from the bottom to top flue gas flow rate from fast to slow, the not portable slurries of upper smoke gas velocity can reduce the burden of demister, help reducing the amount of carrying of the dust such as gypsum in the clean flue gas;
6, realize the energy-efficient operation in absorption tower at 20-100% load band;
7, the energy-conservation 15-25% in more traditional absorption tower under the identical operating mode.
Description of drawings
Accompanying drawing is an embodiment of the invention structural representation.
The specific embodiment
Desulfuration absorbing tower with rounding taper type spray district; Shown in accompanying drawing; It comprises spray type desulphurization absorption tower body of the tower 1, and 2～3 layers of foot spray district 11 become big from bottom to top gradually, can prevent that flue gas from escaping and slurries directly descend slowly and lightly in stock tank 12, help the rounding taper type that slurries are recycled for sectional area in the body of the tower 1.
Body of the tower 1 sidewall in spray district 11 is circular straight-tube shape, is provided with big periphery young, suitable for reading down suitable for reading in 2～3 layers of spray district 11 of body of the tower 1 interior foot and is fixed on the truncated cone tube 2 on body of the tower 1 internal perisporium.The end opening of truncated cone tube 2 is positioned at the below of foot spraying layer 13.Be connected to a fixed through the retainer ring 3 that inner edge is connected on truncated cone tube 2 end openings, the outside is connected on body of the tower 1 inwall between the end opening of truncated cone tube 2 and body of the tower 1 inwall.The sectional area of truncated cone tube 2 end openings is 35%～60% of sectional areas suitable for reading.
