Detailed description of the invention
Such as Fig. 1: wherein air vent 1, dedusting chamber 2, air inlet 3, water conservancy diversion are caught and dripped screw mechanism 4, tangential injection system 5, water conservancy diversion vertebral body 6, gravity ash discharging mechanism 7, lower ash silo vertebral body 8, ash discharging mechanism 9, sensor 10；
Such as Fig. 2: air inlet 11 of wherein tangentially jetting, water sucking mouth 12, tangential winding-up air vent 13, trunnion 14.
As shown in Figure 1: one is tangentially jetted cyclone dust extractor, catch drip screw mechanism 4, tangential injection system 5, water conservancy diversion vertebral body 6, gravity ash discharging mechanism 7, lower ash silo vertebral body 8, ash discharging mechanism 9, a sensor 10 including air vent 1, dedusting chamber 2, air inlet 3, water conservancy diversion.
Cleaner unit body includes dedusting chamber 2, and dedusting chamber 2 is the cavity of a cylindricality.Being additionally provided with air inlet 3 on top, dedusting chamber 2, air inlet 3 is the tube of a rectangle.One limit of air inlet 3 and the tangent setting of periphery in dedusting chamber 2, meanwhile, the intracavity inter-connection in air inlet 3 and dedusting chamber 2.Thus the air needing dedusting is entered and flow into dedusting chamber 2 from air inlet 3, air is carried out convolution and accelerates.Home position in dedusting chamber 2 is additionally provided with air vent 1, and air vent 1 is a cylindrical shaped body, and air vent 1 is fixed on dedusting chamber 2.
Be additionally provided with water conservancy diversion vertebral body 6 in the lower end in dedusting chamber 2, water conservancy diversion vertebral body 6 is a cone, and the top, junction in dedusting chamber 2 with water conservancy diversion vertebral body 6 is provided with tangential injection system 5, and the lower end of water conservancy diversion vertebral body 6 is connected to gravity ash discharging mechanism 7.Gravity ash discharging mechanism 7 lower end is lower ash silo vertebral body 8 and ash discharging mechanism 9.Gravity ash discharging mechanism 7, lower ash silo vertebral body 8 and ash discharging mechanism 9 are arranged concentrically.
As shown in Figure 2: tangential injection system 5 includes tangentially jet air inlet 11, water sucking mouth 12, tangential winding-up air vent 13, trunnion 14, described trunnion 14 connects tangential winding-up air inlet 11 and tangential winding-up air vent 13, trunnion 14 stays an aperture, accesses the water sucking mouth 12 of suction pipe shape.
In use, flue gas is entered dedusting chamber 2 with certain intake velocity by air inlet 3 to the present invention, and the overwhelming majority of swirling eddy is moved along the wall in dedusting chamber 2 in the shape of a spiral from top to bottom from cylinder bottom cone, forms the outward turning dust-contained airflow declined.The grit that density is far longer than gas by produced centrifugal force in strong rotary course gets rid of to wall, grit is once contact with wall, and the momentum and the gravity of self water conservancy diversion along wall that just lose inertia force and lean on entrance velocity to produce are caught and dripped entrance water conservancy diversion vertebral body 6 bottom, screw mechanism 4 whereabouts.Rotate decline air-flow arrive water conservancy diversion vertebral body 6 cone at the bottom of after, axis part along cleaner unit is transferred upwards, form the interior rotational gas flow risen, remain less grit by tangential injection system 5, being sprayed into by a small amount of water smoke according to Gas Parameters, the less grit in air-flow combines with moisture content, makes the volume of grit become big, or accelerate collision with the grit of other water contents and combine, forms bigger granule and caught a screw mechanism 4 by water conservancy diversion again and lead water conservancy diversion vertebral body 6 bottom.The dust arriving gravity ash discharging mechanism 7 is collected owing to falling into ash discharging mechanism 9 again after the lower ash silo vertebral body 8 of action of gravity entrance, and final purification gas rises in cleaner unit central axis, and is discharged by the air vent 1 of cleaner unit.
Tangential injection system 5 is when effect, a small amount of flue gas is entered system by air inlet 11 of tangentially jetting, flue gas flow velocity when entering trunnion 14 position narrowed suddenly becomes big, vacuum state occurs, a small amount of water is sucked trunnion 14 by water sucking mouth 12 by vacuum, spray with the form of water smoke air vent 13 of tangentially being jetted under the high speed pressure of flue gas, enter dedusting chamber 2.
The inwall in dedusting chamber is additionally provided with multiple sensor 10, it can detect in air outlet that parameters such as flowing through flue-gas temperature, humidity, dust content is transferred to control system, winding-up acceleration is carried out to injection system 5 when the flow velocity of flue gas slight drag enters device rear cutout, water smoke is sprayed into along flow of flue gas direction, so both increase the effect of rotational flow dust-removing, also reduce the resistance of device；Sensor 10 collects the parameters such as the temperature of flue gas, humidity, dust content to control system simultaneously, and the humidity of the flue gas in control system control device is not higher than 60%；Water conservancy diversion on the inwall of dedusting chamber 2 is caught a screw mechanism 4 and had both been played the effect of water conservancy diversion, has subtracted again the splashing of dust, has also trapped water droplet, thus reaching the purpose of water-dust removing simultaneously.
Above an embodiment of invention is described in detail, but institute's content has been only present pre-ferred embodiments is not to be regarded as limiting the scope of the present invention.All equalizations done according to the present patent application scope change and improvement etc., all should still belong to the patent covering scope of the present invention.
