Background technology
At present, the gas scrubbing absorption plant mainly contains packed absorber, spray column, Venturi tube, percussion flow blended absorbent device, eddy flow or eddy current washing absorption plant etc., and these devices have advantage and the scope of application separately.But they have shortcomings such as complex structure, volume is big, cost is high, resistance is big, to energy consumption in the gas scrubbing absorption process than higher, particularly lower for concentration, recycle and be worth little industrial waste gas, medium and small boiler flue gas, kitchen fume etc., the shortcoming that their investment operating cost is high just highlights more, and they all are not suitable for the gas flow fluctuation than the operating mode that contains dust in big and the air-flow.
Summary of the invention
, investment operating cost height big for the volume that overcomes gas scrubbing absorption plant commonly used, resistance are big, the shortcoming of restricted application, the invention provides a kind of simple in structurely, cost is low, and resistance is little, be applicable to the tolerance fluctuation, and the high gas scrubbing absorption plant of efficient.
The present invention adopts Venturi tube structure, utilizes flue structure that gas-liquid mixed stream is compressed, and then speedup forms the mixing principle of turbulent flow, and has utilized the mixing principle of gas-liquid eddy current mixing principle and percussion flow.
Efficient low-resistance strength body washing absorption plant is that solid-cone spray atomization system is set on rectangle gas pipeline top, a nozzle below certain distance setting airflow-distribution board parallel with the gas pipeline center line, the airflow-distribution board below connects the gas-flow deflector that forms an angle with pipe centerline, what the gas-flow deflector below connected is the vortex board that certain curvature radius and central angle arranged tangent with gas-flow deflector, and the vortex board below is welded to connect and gas pipeline center line parallel gas flow guiding plate.Respectively one of airflow-distribution board, gas-flow deflector, scroll plate, air-flow guiding plate, be connected with mode by said sequence, common constitute a mixing, washing plate system, the space between two mixing, washing plate at regular intervals systems forms the special gas channel that can efficiently carry out gas-liquid mixed.Can arrange a plurality of mixing, washing plate system in the gas pipeline of a cross section rectangle, contour setting on the short transverse, the horizontal direction equal intervals arranges, the level interval between two mixing, washing plate systems is determined according to the shape size of gas flow, pipeline section size, vortex board.The gas channel integrated use that constitutes between two adjacent mixing, washing plate systems the mixing principle of venturi turbulent flow, percussion flow, vortex flow.When gas-liquid mixture fluid during by the gas channel between two plate systems, pass through processes such as supercharging deceleration, vortex, bump, decompressing speed-increasing successively, thereby increased the gas-liquid mixed time, strengthened the affixed tactile mixed effect of gas-liquid or gas-liquid.A plurality of mixing, washing plate system, rectangle gas pipeline, spray system and two flanges have constituted efficient low-resistance strength body washing absorption plant jointly.
The present invention is the efficient low-resistance strength body washing absorption plant of no-movable part, and it is simple in structure, and volume is little, make easy for installationly, resistance is little, washing absorption efficiency height, investment operating cost is low, and is applicable to that containing the big gas scrubbing of dusty gas and gas flowed fluctuation absorbs.The present invention has fully utilized Venturi tube washing mixing principle, eddy current and percussion flow mixing principle, realize by the special gas channel that a plurality of mixing, washing plate systems and rectangle gas pipeline constitute, thereby reached the gas-liquid mixed full contact, washing absorption efficiency height.
