Background technology
National environmental protection portion promulgated " fossil-fuel power plant atmospheric pollutant emission standard " (GB13223-2011) in 2011, improve the discharge standard of sulfur dioxide.Specify in standard, from 1 day July in 2014, new construction of coal-fired boiler sulfur dioxide in tail gas emission limit was 100mg/Nm
3, key area emission limit is 50mg/Nm
3.Key area includes Jing-jin-ji region, the Yangtze River Delta, Pearl River Delta and other key cities totally 47.After 2013, along with haze more and more comes into one's own in most of China area, various places environmental administration has made stricter limit value to the sulfur dioxide (SO2) emissions limit value of coal-burning power plant one after another, and in some key areas, the emission limit of requirement is even lower than 50mg/Nm
3, under such background condition, need application high-efficiency desulfurization technology could meet new standard requirement.At present in the area of key area and ature of coal condition deviation, the desulfuration efficiency of traditional single tower single cycle desulphurization system has been difficult to the new demand reaching above-mentioned country and local environmental administration.Current counter-measure mainly uses single tower Two-way Cycle technology or between absorption tower entrance and ground floor spraying layer, arranges single or two pallets, to reach the object improving desulfuration efficiency.
As mentioned above, what prior art belonged to high-efficiency desulfurization technology range of application mainly contains single tower Two-way Cycle technology and single, double tray technology.Single tower Two-way Cycle technology has efficient, stable advantage, but shortcoming involves great expense, and improves 40-50% than traditional desulphurization system cost.
Single, double tray technology installs perforated trays between absorption tower entrance and ground floor spraying layer, the circular hole manufacturing process more complicated of perforated trays, its device raw material selection be expensive high-strength alloy material, and due to the feature of its porous, cause pallet that the situations such as blocking easily occur.Pallet can strengthen gas-liquid mass transfer efficiency in normal operating conditions; improve desulfuration efficiency; but once block; flow field in whole absorption tower can become more uneven; increase the liquid flux of not blocking portion simultaneously; and then cause more serious blocking, need maintenance down even in some cases.
Utility model content
In order to solve the problem, the purpose of this utility model is to provide a kind of wet desulphurization to put forward the turbulence device of effect, can be installed in conventional suction tower, to improve mass-transfer efficiency device.On the basis of uniform flue gas flow field, effectively rectification flue gas, make grout distribution even, improve SO in flue gas
2and the mass-transfer efficiency between drop, increase gas liquid interfacial area, thus improve desulfuration efficiency.
For achieving the above object, the scheme that the utility model is taked is:
A turbulence device for effect is put forward in wet desulphurization, in order to be installed at absorbing tower smoke inlet on the upside of and between spraying layer, comprise a turbosphere: comprise two-layer above turbosphere pipeline, described turbosphere pipeline comprises some pipes be arranged in parallel; Also comprise and described turbosphere pipeline is fixed on some articulated stands in absorption tower and some brace summers; Be staggeredly arranged in parallel between each layer of described turbosphere pipeline.
Further, described pipe is rubber lined steel pipe.
Further, the diameter of described rubber lined steel pipe is Φ 45 ~ Φ 100mm.
Further, the staggered distance be staggeredly arranged in parallel described in is 0.5-1 times of aforementioned diameter.
Further, the distance between the turbosphere pipeline of adjacent layer is 0.5 ~ 1.0 times of aforementioned diameter.
Further, shared by individual layer turbosphere pipeline, the porosity of level cross-sectionn, absorption tower is between 0.3 ~ 0.6.
Further, described turbosphere Pipe installing position be absorption tower smoke inlet above 2 ~ 4 meters of.
As mentioned above, the utility model adopts the rubber lined pipe be staggeredly arranged in parallel to replace traditional perforated trays, and process for machining and manufacturing is very simple, convenient for installation and maintenance, can not only improve mass-transfer efficiency, can avoid in blocking simultaneously.
Compared to traditional scheme, the device form that the utility model proposes is under the prerequisite that can reach effect same, but simpler to the requirement of manufacturing process, the cost of material is low for it, and structure is simple, and load is little, not easily block, efficiency is high, and do not increase additional floor space, operating cost is low, maintenance management is easy, has high application value.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 be in Fig. 1 A-A to sectional view.
Detailed description of the invention
For making above-mentioned feature and advantage of the present utility model become apparent, special embodiment below, and coordinate institute's accompanying drawing to be described in detail below.
Embodiment:
As shown in Figures 1 and 2, the turbulence device of effect is put forward in wet desulphurization provided by the utility model, in order to be installed in absorption tower.It comprises a turbosphere: described turbosphere comprises the two-layer turbosphere pipeline be staggeredly arranged in parallel.Turbosphere pipeline adopts parallel rubber lined steel pipe, and not only light weight is inexpensive, and corrosion resistance is strong.Certainly, according to different operating modes, also can install multilayer turbosphere pipeline additional in an absorbing tower, this utility model is not limited.
