Description
Technical field
The utility model relates to a kind of desulfuration absorbing tower, and more specifically it is a kind of secondary Zigzag type desulfuration absorbing tower.
Background technology
In " 12 " period, China's industrialization and urbanization will be fast-developing, and resources and energy consumption sustainable growth, atmospheric environment will face unprecedented pressure.On September 12nd, 2014; National Development and Reform Commission, Environmental Protection Department, National Energy Board combine issue " coal electricity energy-saving and emission-reduction upgrading and transformation action plan (2014-the year two thousand twenty) "; action target is proposed: eastern region newly-built Thermal generation unit Air Pollutant Emission concentration reaches gas turbine group emission limit substantially; middle part new-built unit in principle close to or reach gas turbine group emission limit, encourage west area new-built unit close to or reach gas turbine group emission limit.Meanwhile, environmental administration also " cracks down ", Thermal Power Enterprises is proposed to the discharge standard of more and more " harsh ".In this context, technological transformation and the construction of new round coal-burning power plant Environmental capacity launch, and " ultra-clean discharge ", " near-zero release " etc. become recent " hot word ".
So-called ultra-clean discharge, refers to and uses multiple pollutant process for comprehensively treating, makes thermal power plant's Air Pollutants (flue dust, sulfur dioxide, nitrogen oxide) discharge the Air Pollutant Emission limit value reaching or be better than gas turbine group.If coal-burning power plant can realize " ultra-clean discharge ", the discharge of major pollutants will significantly reduce in theory, this means that coal electricity can realize Green Development, both can ensure electric power safety supply, can contribute again to control atmosphere pollution.
Traditional absorption tower is generally spray void tower, and the desulfuration efficiency Absorbable organic halogens of this technology reaches 95%, and efficiency of dust collection is 60%.
Utility model content
The purpose of this utility model in order to overcome the weak point of above-mentioned background technology, and provides a kind of secondary Zigzag type desulfuration absorbing tower.
To achieve these goals, the technical solution of the utility model is such: the absorption tower body, spraying layer, the demister that export with absorption tower entrance and absorption tower, described absorption tower body also comprises one-level spray reaction zone, transition region, secondary blistering reaction district and region, four, stock tank district, absorption tower, and described one-level spray reaction zone, secondary blistering reaction district dividing plate separate;
Described one-level spray reaction zone comprises absorption tower entrance, porous distributor, spraying layer, and described absorption tower entrance is positioned at above the stock tank of absorption tower; Described spraying layer is positioned at absorption tower entrance top;
Described transition region is positioned at absorption tower bodies top; Described transition region top is arc;
Described secondary blistering reaction district comprises smoke distribution room, air jet pipe, absorption tower outlet, smoke distribution room is arranged in below transition region, spray reaction zone with one-level to be communicated with by transition region, air jet pipe is positioned at bottom, smoke distribution room, submerge in the slurries of absorption tower bottom air jet pipe, absorption tower outlet is between smoke distribution room and absorption tower slurries;
Described stock tank district, absorption tower is positioned at absorption tower body bottom portion, comprises stock tank body and absorption tower slurries;
Also demister is furnished with at described absorption tower exhaust pass.
In technique scheme, porous distributor is installed between absorption tower entrance and spraying layer.
In technique scheme, porous distributor is installed between two-layer spraying layer, and described spraying layer is three to six layers.
The beneficial effects of the utility model are: compare traditional sky and spray tower, its distinctive twin-stage absorbing structure, the problem of the ultra-clean discharge of flue gas desulfurization can be solved preferably, can meet that desulfuration efficiency is more than 99%, efficiency of dust collection is the requirement of 85%, be mainly reflected in:
One is in one-level spray reaction zone, flue gas is first by porous distributor, good uniform effect is obtained by the flue gas after porous distributor, in major part region, flue gas flow rate is comparatively close, in addition, the turbulent motion of flue gas and slurries can be strengthened when the liquid film that porous distributor is held makes flue gas flow through aperture further, be conducive to improving absorption tower desulfuration efficiency;
Two is the bubble layers formed in secondary blistering reaction district, is the main region of gas-liquid mass transferring, due to the sharp impacts of gas-liquid, and the better dust removal effect in this region;
Three is in transition region, and flue gas flow direction is turned back, and flow velocity progressively improves, and the top of arc makes flue gas flow rate more steady, reduces the crushing of local.
