Embodiment
See also Fig. 1, the structural representation of the swirl-spray humidifying tower that provides for the utility model.Mainly comprise:
One tower body is combined by cylindrical tube 9, cylindrical changeover portion 4 and conical contraction section 7, this tower body bottom offers waste pipe 14, be the pressure in the control tower simultaneously, water seal and tank level control system also are housed, can keep certain water level in the damping machine, realize pressure control (tank level control system is a known technology, and is not shown).The tower body top offers outlet pipe 1, in order to discharge the high-pressure air through warming and humidifying.Top in the tower body 9 and the below that is positioned at outlet pipe 1 are provided with intake pipe 3, connect a liquid-jet device through this intake pipe 3, liquid-jet device is made up of a plurality of atomizer nozzles 6 that are installed on the nozzle fixed base 5, and high-temperature water forms fine droplet by intake pipe 3 through atomizer nozzle 6 and is dispersed in whole tower section.
The bottom of tower body and be positioned at waste pipe top and be provided with a suction tude 13 is equipped with air sparger 12 on this suction tude 13.This air sparger 12 as shown in Figure 3, outer Taper Pipe 15 and endosiphuncular tube 16 by coaxial arrangement constitute, two Taper Pipes are arranged according to confocal point, outer Taper Pipe height is higher than the endosiphuncular tube height, 8 swirl vanes of evenly arranging 17 of welding between the inside and outside Taper Pipe, make the air that enters form the Rotating with Uniform air-flow and flow to the tower body top, the relative tilt angle of conversion blade and axis can be regulated the into swirl strength of tower air.
In having the swirl-spray tower of said structure, pressurized air is through air sparger 12, a part is sentenced homogeneous velocity by endosiphuncular tube 16 at tower axis and is entered tower body, another part enters tower body by swirl vane 17 with rotation mode, under the drive of swirling eddy, the axle center uniform air flow also rotates; High temperature drop and swirling eddy reverse contact in tower body that intake pipe 3 injects carry out dropping down onto the tower body bottom from waste pipe 14 discharges behind the heat and mass with air; Air through warming and humidifying is discharged from the top outlet pipe 1 of tower body.
In practical operation, have the sub-fraction fine droplet along with swirling eddy is up, for removing these drops, in tower body, be positioned at below the outlet pipe and spray equipment above demister 12 is installed, force with the up fine droplet of air-flow and hit wall and be captured, thereby finish dewatering or demist of exhaust gas body.The demister that the utility model adopts can be known inertia demister.
Form wall stream for preventing on the tower body internal face because the centrifugal action that the air-flow rotation causes is thrown to drop, be positioned at the atomizer nozzle below around wall air intake device 8 is installed around the tower body; See also Fig. 4, wall air intake device 8 comprises internal air baffle 18, outer wind deflector 19, suction port 20 and chuck 21, and inside and outside wind deflector is annular corner structure, and opposite direction is arranged, surrounds the wall air-flow air intake passage of annular by cooperation.Suction port 20 can also can evenly be arranged the equal diameter circular hole along circumference for band shape; Chuck 21 can also play the effect that keeps the tower internal pressure except the connected element as tower.The contraction section place of air-flow in tower body that is sprayed into by wall air intake device 8 forms one deck air film, thereby prevents to form wall stream on the tower body internal face because centrifugal action is thrown to drop.
In sum, the humidifying tower that is provided by the utility model can increase the waiting time of drop in tower body to increase the heat and mass between the gas-liquid, reduces because the pressure loss that the gas-liquid counter current contact flow is caused also can avoid the drop wall built-up to form wall stream in addition.
