Abstract
The invention relates to a slurry collecting disc for a spray type desulfurization absorption tower, which comprises a plurality of blocks of slurry collecting disc pore plates (1). Each slurry collecting disc pore plate (1) is a plate-shaped body formed by arranging a plurality of smoke through holes (11) between an upper plate face and a lower plate face, the slurry collecting disc pore plates (1) are mutually spliced to form a plate shape and are horizontally installed between a spray layer and a smoke inlet at the lowest portion in the desulfurization absorption tower, and gaps for slurry to naturally flow down are arranged between parts of the slurry collecting disc pore plates (1). The porous structure of the slurry collecting disc for the desulfurization absorption tower can evenly distribute the smoke inside the adsorption tower and has good desulfurization effect, thereby solving the problems of bias flowing and lateral wall escape flowing of the smoke inside the spray type absorption tower, collecting and effectively utilizing the slurry falling down inside the spray type adsorption tower. By means of the slurry collecting disc, liquid-gas ratio of the adsorption tower can be reduced, and energy consumption of a slurry circulating pump is greatly reduced.
Description
Technical field
The present invention relates to flue gas desulfur device, be specifically related to a kind of desulfuration absorbing tower slurry collecting disc.
Background technology
Absorption tower be a kind of by physics or chemical method by the SO in flue gas
2the device of removing Deng pernicious gas or structures.In multiple desulfuration absorbing tower, having a class absorption tower is spray absorption tower, the main working process of spray absorption tower is to utilize slurry circulating pump to be transported to by absorbing slurries the spraying layer consisting of a plurality of nozzles, after absorbing the atomizer ejection of slurries by spraying layer, form intensive atomization slurry spray district, slurries contact with flue gas in atomizing spray district, absorb the SO in flue gas
2deng pernicious gas, complete flue gas desulfurization, slurries descend slowly and lightly in the stock tank of bottom, absorption tower along inside, absorption tower.
One of factor that at present affects spray absorption tower desulfurized effect is inner flue gas bias current: due to the reason of spraying layer pipeline and arrangement of nozzles, cause spraying layer slurries injection density inhomogeneous, and then cause resistance skewness, the region flue gas flow rate that flue gas resistance is little is fast, produce flue gas bias current, affect desulfurized effect; The 2nd, smoke absorption tower side wall is escaped stream: low at the spraying layer sprinkle density of pressing close to absorption tower sidewall, press close to the resistance that near the flue gas of absorption tower sidewall is subject to less, cause the fast phenomenon of flue gas flow rate of absorption tower sidewall, sidewall is escaped stream and is also had a strong impact on desulfurized effect.
SO in the absorption flue gas of existing spray absorption tower slurries between smoke inlet and spraying layer
2in the slurries district directly descending slowly and lightly after pernicious gas into bottom, absorption tower, the slurries that spray absorption tower inside can not be descended slowly and lightly collected and are used before falling into slurries district.
Summary of the invention
The object of this invention is to provide a kind of inner flue gas bias current of spray absorption tower and sidewall of can solving and escape the slurry collecting disc for spray type desulfurization absorption tower that flow phenomenon, desulfurized effect slurries better, that spray absorption tower inside can be descended slowly and lightly collect.
Technical solution of the present invention is: it comprises the slurry collecting disc orifice plate of some, each slurry collecting disc orifice plate is respectively the plate body that is provided with a plurality of smoke ventilators between upper and lower plates face, each slurry collecting disc orifice plate pieces together mutually tabular level and is arranged in spray type desulfurization absorption tower between foot spraying layer and smoke inlet for the inner flue gas in uniform absorption tower, solves flue gas bias current and sidewall is escaped stream, is provided with the gap of the downward slurries that naturally trickle between part slurry collecting disc orifice plate.
Technique effect of the present invention is: the loose structure of desulfuration absorbing tower slurry collecting disc can be uniform the inner flue gas in absorption tower, desulfurized effect is better, can solve the inner flue gas bias current of spray absorption tower and sidewall and escape flow phenomenon, the slurries that spray absorption tower inside can be descended slowly and lightly collect and it are effectively utilized.Use it can reduce absorption tower liquid-gas ratio, significantly reduce slurry circulating pump energy consumption.
accompanying drawing explanation
