Description
Technical field
The utility model relates to wet desulfurization of flue gas by limestone-gypsum method equipment, is specifically related to the turbulence device that effect is put forward in a kind of wet desulphurization.
Background technology
National environmental protection portion has promulgated < < fossil-fuel power plant atmospheric pollutant emission standard > > (GB13223-2011) in 2011, improved the discharge standard of sulfur dioxide.In standard, stipulate, 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 has comprised totally 47 of Beijing-Tianjin Ji, the Yangtze River Delta, Pearl River Delta and other key cities.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 to apply high-efficiency desulfurization technology and could meet new standard requirement.At present in key area and the area of ature of coal condition deviation, the desulfuration efficiency of traditional single tower single cycle desulphurization system has been difficult to reach the new demand of above-mentioned country and local environmental administration.Current counter-measure is mainly use the two circulating technologies of single tower or single or two pallets are set between absorption tower entrance and ground floor spraying layer, to reach the object that improves desulfuration efficiency.
What as mentioned above, prior art belonged to high-efficiency desulfurization technology range of application mainly contains the two circulating technologies of single tower and single, double pallet technology.The two circulating technologies of single tower have advantages of efficient, stable, but shortcoming is to involve great expense, and than traditional desulphurization system cost, improves 40-50%.
Single, double pallet technology is, between absorption tower entrance and ground floor spraying layer, porous pallet is installed, the circular hole manufacturing process more complicated of porous pallet, what it installed raw material selection is expensive high-strength alloy material, and due to the feature of its porous, cause pallet that the situations such as obstruction easily occur.Pallet can strengthen gas-liquid mass transfer efficiency under normal operation; improve desulfuration efficiency; once yet stop up; it is more inhomogeneous that flow field in whole absorption tower can become; increase the not liquid flux of blocking portion simultaneously; and then cause more serious obstruction, need even in some cases to shut down maintenance.
Utility model content
In order to address the above 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 traditional absorption tower, to improve mass-transfer efficiency device.On the basis of uniform flue gas flow field, effective rectification flue gas, make grout distribution even, the mass-transfer efficiency in raising flue gas between SO2 and drop, increases gas-liquid contact area, thereby improves 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 between the smoke inlet upside and spraying layer of absorbing tower, comprises a turbosphere: comprise two-layer above turbosphere pipeline, described turbosphere pipeline comprises some elliptical tubes that are arranged in parallel; Also comprise described turbosphere pipeline is fixed on to some articulated stands and the some brace summers in absorption tower; Between described each layer of turbosphere pipeline, be staggeredly arranged in parallel.
Further, described elliptical tube is rubber lined steel pipe.
Further, the major diameter of described rubber lined steel pipe is Φ 50～Φ 84mm.
Further, the 0.5-1.0 that the staggered distance being staggeredly arranged in parallel described in is aforementioned major diameter doubly.
Further, the distance between the turbosphere pipeline of adjacent layer is aforementioned major diameter 0.5～1.0 times.
Further, the porosity of level cross-sectionn, the shared absorption tower of individual layer turbosphere pipeline is between 0.3～0.6.
Further, 2～4 meters of, smoke inlet top that described turbosphere pipeline installation site is absorption tower.
As mentioned above, the utility model adopts the rubber lined pipe being staggeredly arranged in parallel to replace traditional porous pallet, and process for machining and manufacturing is very simple, convenient for installation and maintenance, not only can improve mass-transfer efficiency, can avoid stopping up simultaneously.
Compared to traditional scheme, the device form the utility model proposes can reach under the prerequisite of effect same, but simpler to the requirement of manufacturing process, the cost of material is low for it, simple in structure, and load is little, be difficult for stopping up, efficiency is high, and do not increase extra 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 cutaway view.
The specific embodiment
For above-mentioned feature and advantage of the present utility model can be 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 being staggeredly arranged in parallel.Turbosphere pipeline adopts parallel oval rubber lined steel pipe, and not only light weight is inexpensive, and corrosion resistance is strong.Certainly, according to different operating modes, in an absorbing tower, also can install multilayer turbosphere pipeline additional, this utility model is not limited.
