The specific embodiment
The utility model embodiment comprises the purification pipe with gas approach 1 and exhanst gas outlet 2, it is characterized in that: (1) described gas approach part is shape in the shape of a spiral, so that the axial line of the relative purification pipe of flue gas of input circles round; (2) be provided with the backspin swirl-flow devices in the purification body, described swirl-flow devices has some backspin eddy flow prerotation vanes 3 that distribute along purification pipe cross section perimembranous; (3) be provided with mouth spray 4 in the described purification pipe, described mouth spray be oriented to the tangential direction identical with the flue gas direction of rotation.
For flue gas being carried out desulfurization simultaneously when the dedusting, above-mentioned mouth spray is connected with the desulfurizing agent liquid feed device, and described desulfurizing agent is an akaline liquid.When desulfurizing agent when the tangential direction identical with the flue gas direction of rotation sprays in the purification pipe, can make desulfurizing agent and flue gas mix rotation at a high speed, in dedusting, can realize effectively removing the purpose of sulfur dioxide again.
In order to strengthen clean-up effect, above-mentioned purification pipe comprises that sidepiece has a gas approach perpendicularly puts outer smoke pipe 5 and perpendicularly is located at the perpendicular internal flue of putting in the foreign cigarette body 6, be provided with taper ring set 7 between the following side of described inside and outside smoke pipe, the internal flue that is positioned at taper ring set downside stretches to beneath sewage accommodates cabinet 8, and the air inlet that is positioned at the internal flue of conical ring cover upside is provided with eddy flow guide vane 9.
The above-mentioned perpendicular outer smoke pipe top of putting is provided with the smoke exhaust pipe isolated with it 10, the upper shed of described internal flue is passed division board 11 and is stretched into smoke exhaust pipe, be provided with in the described smoke exhaust pipe be positioned in the internal flue upper shed on revolve demister, revolve on described demister have some along smoke exhaust pipe cross section perimembranous distribute on eddy flow prerotation vane 12; Described smoke exhaust pipe internal perisporium is provided with and is positioned at the back-up ring 13 that revolves the demister top.
Above-mentioned sewage is accommodated the lower port 14 that the water surface in the cabinet flooded internal flue, and sewage accommodates cabinet and be provided with towards the overflow passage 16 in low level mixed precipitation pond 15, and top, described mixed precipitation pond is provided with desulfurizing agent feeding pipe device; Described mixed precipitation pond one side is provided with coupled logical purification water tank 17, purifies waste water and is provided with water pumping pipe road device 18 cashier's office in a shop, and described mouth spray is connected with the water pump output of water pumping pipe road device.
