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 device that improves wet desulfurization system mass-transfer efficiency, can be installed in conventional wet desulfuration spray tower, to improve mass-transfer efficiency device.On the basis of uniform flue gas flow field, effective rectification flue gas, make grout distribution even, improve SO in flue gas
2and the mass-transfer efficiency between drop, increase gas-liquid contact area, thereby improve desulfuration efficiency.
For achieving the above object, the scheme that the utility model is taked is:
Improve a device for wet desulfurization system mass-transfer efficiency, in order to be installed between the gas approach upside and ground floor spraying layer of desulfuration spray tower, comprising: two-layer above turbosphere pipeline, described turbosphere pipeline comprises some pipes that are arranged in parallel; Also comprise described turbosphere pipeline is fixed on to some articulated stands and the some brace summers in desulfuration spray tower; Described turbosphere pipeline arranged crosswise.
Further, described pipe is rubber lined steel pipe.
Further, the diameter of described rubber lined steel pipe is Φ 45～Φ 100mm.
Further, the angle of described arranged crosswise is 90-120 °.
Further, the distance proportion between the turbosphere pipeline of adjacent layer is caliber between 0.5～1.0.
Further, the porosity of the shared desulfuration spray tower of individual layer turbosphere pipeline level cross-sectionn is between 0.3～0.6.
Further, described turbosphere pipeline installation site is for departing from 2～4 meters of, gas approach top of spray column.
As mentioned above, the utility model adopts the rubber lined pipe of arranged crosswise to replace traditional porous pallet, is combined into the arrangement of groined type, 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.
