technical field:
the utility model relates to a kind of desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus.
background technology:
flue gas desulfurization technique that large Limestone-gypsum Wet Flue Gas Desulfurization Process technology company of current domestic a few family introduces is mainly from 1) Japanese Ren Yuan company; 2) Kawasaki, Japan heavy industry; 3) Germany is than Xiao Fu company; 4) German Si Tan Miller company; 5) U.S. Marsulex Environmental Technology AS; 6) U.S. Ba Wei (B & W) company; 7) Austria Energy and Environment joint-stock company (AEE); 8) French Alstom (ALSTON) company; 9) Mitsubishi Heavy Industries Ltd etc. several flue gas desulfurization technique support side, the design concept such as the many employing sprays of tower, bubbling, fluid column of the fume desulfurizing tower applied; Traditional desulphurization and denitration technique, its cost is higher, easy fouling and can produce secondary pollution.
summary of the invention:
the purpose of this utility model is to provide a kind of desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus.
above-mentioned object is realized by following technical scheme:
a kind of desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus, its composition comprises: a two phase countercurrent flow sieve tray, and described sieve tray upper surface is provided with cell isolation plate,
described cell isolation plate is welded on sieve tray.
described desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus, the height of described cell isolation plate is 50mm, after described cell isolation plate has welded, sieve tray is divided into 16 unit.
described desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus, is characterized in that: described two phase countercurrent flow sieve tray is arranged on the middle and lower part of desulphurization and denitration spray column and liquid column tower, after gas approach.
the beneficial effects of the utility model:
1. the utility model is pulsed regularly between air-flow and liquid stream to ensure, prevent pulsation excessive, cause air-flow flux uneven, the pressure drop that device produces further promotes again the uniformity of smoke distribution, for the gas-liquid uniform contact of spraying layer scrubbing section provides more good guarantee.
the operating efficiency that apparatus structure of the present utility model is novel, efficiency is high, improve desulphurization and denitration tower, reduces floor space, has saved the investment of desulphurization and denitration tower, improves the input-output ratio of desulphurization and denitration.
accompanying drawing illustrates:

detailed description of the invention:
embodiment 1:
a kind of desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus, its composition comprises: a two phase countercurrent flow sieve tray, and described sieve tray 1 upper surface is provided with cell isolation plate 2,
described cell isolation plate is welded on sieve tray.
embodiment 2:
desulphurization and denitration flue gas even distribution according to embodiment 1 and gas-liquid area aggrandizement apparatus, the height of described cell isolation plate is 50mm, after described cell isolation plate has welded, sieve tray is divided into 16 unit.
embodiment 3:
desulphurization and denitration flue gas even distribution according to embodiment 1 or 2 and gas-liquid area aggrandizement apparatus, described two phase countercurrent flow sieve tray is arranged on the middle and lower part of desulphurization and denitration spray column and liquid column tower, after gas approach; Described desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus, its operation principle is: flue gas forms froth bed at desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus upper surface, and slurries also therefrom fall simultaneously; Pulse regularly between air-flow and liquid stream, between air-flow and liquid stream, pass through aperture; Division board on desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus is to prevent pulsation excessive, causing air-flow flux uneven; Special after desulfurization diameter increases, if without division board, namely there will be and have some holes only to ventilate to fall the phenomenon of liquid, some is then just contrary, and this certainly will will have a strong impact on mass transfer between gas-liquid, reduction desulfuration efficiency; Because each isolated area of desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus has multiple path to exist, this TRANSFER BY PULSATING FLOW can be considered that quasi-steady state is flowed; The pressure drop produced further promotes the uniformity of smoke distribution, for the gas-liquid uniform contact of spraying layer scrubbing section provides more good guarantee; The pressure drop that desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus produce is made up of three parts: one is the dry-plate pressure drop of desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus; Two is pressure drops that surface tension produces; Three be desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus upper surface froth bed produce differential static pressure; The dry-plate pressure drop of desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus is that flue gas produces when accelerating through aperture, the pressure drop that surface tension produces is the surface tension in order to overcome between gas-liquid, for circular port, the pressure drop that surface tension produces is the simple function in gas-liquid surface tensile property and aperture; Static pressure reduces to the gas-liquid froth bed generation of desulphurization and denitration flue gas even distribution and gas-liquid area aggrandizement apparatus upper surface, relevant with the height of froth bed.
