Abstract
The utility model discloses a desulfurization and denitrification absorptive reaction tower which comprises a tower body as well as a smoke aeration pipeline, biological reaction area stuffing and an oxidized air pipeline which are arranged in the tower body from bottom to top. The desulfurization and denitrification absorptive reaction tower disclosed by the utility model is simple in structure; and the loss of a biofilm is reduced and the removal efficiency is improved.
Description
Technical field
The utility model relates to a kind of waste gas treatment equipment, particularly a kind of desulphurization denitration absorption reaction tower.
Background technology
Existing absorption reaction tower for bioanalysis while desulphurization denitration is the packed tower composite set of double-column in series formula, and core absorption reaction tower wherein is two packed towers.The basic structure of biological packing tower is cylindrical vertical tower body, in the tower body bottom circulation liquid pool is set, the tower body middle part is filler biofilm district, the layering setting is filled the packing layer that forms by the material of porous media properties, arrange spraying layer on tower body top, spray circulation fluid to packing layer surface and diffuse in the gap by circulating pump, form biomembrane, thereby constantly replenish because contact the biomembrane loss that causes and the loss of moisture with flue gas, the biomembrane of the desulfurization removing nitric performance that filling surface adheres to, with the flue gas contact process in capture SO in the flue gas
2And NOx, reach the effect that purifies flue gas.
In bioanalysis desulphurization denitration practice process, because the original structure packing layer mainly is arranged in gas phase, biomembranous reparation and the additional main spray that relies on, and because the packing layer filler distribution can not be accomplished even fully, resistance has difference everywhere, and therefore biomembranous reparation and additional being difficult to guarantee, gas-liquid contact everywhere simultaneously also is difficult to keep stablizing, influence the operation of system's continous-stable, occur local SO easily
2Descend with the NOx removal efficiency, thereby cause entire system efficient instability.
Biomembrane wherein mainly replenishes by circulated sprinkling in addition, and the desulfurization removing nitric bacterium in the packing layer absorbs SO by the gas-liquid contact reaction that gas phase is dominant
2And NOx, in prior biological packed tower structure, in order to take full advantage of height, simplified structure does not arrange the liquid phase redistributor simultaneously.The trend of leaning on gradually in the tower wall direction set is often arranged when liquid is dirty along packing layer in the tower, and liquid is walked to be short-circuited at the bottom of the tower along the tower wall, has reduced mass transfer effect, has also influenced absorption efficiency.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the utility model discloses a kind of stable operation of guaranteeing gas-liquid contact and reaction, avoid the generation of flue gas or the short circuit of bacterium liquid, reduce biomembranous loss, improve the desulphurization denitration absorption reaction tower of removal efficiency.
Technical scheme: the utility model discloses a kind of desulphurization denitration absorption reaction tower, comprise tower body, be arranged in the tower body, be provided with successively from lower to upper, flue gas aerating pipelines, bio-reaction zone filler and oxidation air pipeline.
Wherein, described bio-reaction zone filler up and down is respectively equipped with pallet and fixes in both sides.
Described flue gas aerating pipelines is made up of by 8 distributor pipes that distribute along circumferential 45 degree of tower body circular cross-section tower body outer ring pipeline, and distributor pipe is communicated to tower body kernel of section point, has radially uniform solarization air cap on the every distributor pipe.The aeration distributor pipe is communicated with by aeration distribution ring pipe, has along circumferential uniform solarization air cap on the same aeration distribution ring pipe.
Bio-reaction zone filler and pallet are formed bio-reaction zone, the bio-reaction zone filler is under bio-reaction zone top tray and the bio-reaction zone between the pallet, the bio-reaction zone filler is closely fixing by pallet under bio-reaction zone top tray and the bio-reaction zone, have uniform gas passage under bio-reaction zone top tray, the bio-reaction zone on the pallet, be used for the passage that passes through of flue gas aeration.Guarantee that aeration evenly distributes and fully gas-liquid contact and reaction at bio-reaction zone.
The utility model has been invented a kind of desulphurization denitration absorption reaction tower to the problem of existing biological packing tower, comprises tower body, is arranged in the tower body, is provided with successively from lower to upper, and flue gas aerating pipelines, bio-reaction zone filler and oxidation air pipeline are full of bacterium liquid in the tower.All porous media materials all are in the liquid phase, have guaranteed biomembranously to replenish and be full of in the whole tower uniformly, thereby have guaranteed that biomembranous stable and uniform exists.The entire reaction tower wraps up gas phase with liquid phase.The gas-liquid contact is carried out under the leading atmosphere of liquid phase.Thereby avoided the liquid short circuit to influence gas-liquid contact effect, thereby reduced mass transfer effect.By special aeration distribution design and column plate distribution design, guarantee the abundant contact of gas-liquid phase, original biological packing tower relies on the oxygen that contains in the flue gas, guarantee the supply of reaction requisite oxygen, local oxygen quantity not sufficient usually appears, form anaerobic environment, thus the carrying out of having destroyed desulphurization denitration bacterium normal biological processes.The utility model is aided with the oxidation air pipeline in the appropriate location between column plate and flue gas aeration tube, thereby guarantee the lasting supply of the biological respinse requisite oxygen amount of desulphurization denitration bacterium, guarantee steadily carrying out of absorption reaction, thereby guaranteed high denitrification efficiency, improved the stability of device operation.
Beneficial effect: the disclosed desulphurization denitration absorption reaction of the utility model tower, simple in structure, reduce biomembranous loss, improve removal efficiency.
