Detailed description of the invention
As Fig. 1: wherein exhaust outlet 1, dedusting chamber 2, air inlet 3, water conservancy diversion are caught and dripped screw mechanism 4, tangential injection system 5, water conservancy diversion centrum 6, gravity ash discharging mechanism 7, lower ash silo centrum 8, ash discharging mechanism 9, sensor 10;
As Fig. 2: air inlet 11 of wherein tangentially jetting, water sucking mouth 12, tangential winding-up exhaust outlet 13, trunnion 14.
As shown in Figure 1: one is tangentially jetted cyclone dust collectors, comprise exhaust outlet 1, dedusting chamber 2, air inlet 3, water conservancy diversion catch and drip a screw mechanism 4, tangential injection system 5, water conservancy diversion centrum 6, gravity ash discharging mechanism 7, lower ash silo centrum 8, ash discharging mechanism 9, sensor 10.
Deduster body comprises dedusting chamber 2, and dedusting chamber 2 is cavitys of a cylindricality.Also be provided with air inlet 3 on top, dedusting chamber 2, air inlet 3 is tubes of a rectangle.A 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 will the air of dedusting be needed to enter from air inlet 3 and flow into dedusting chamber 2, convolution is carried out to air and accelerates.Home position in dedusting chamber 2 is also provided with exhaust outlet 1, and exhaust outlet 1 is a cylindrical shaped body, and exhaust outlet 1 is fixed on dedusting chamber 2.
Also be provided with water conservancy diversion centrum 6 in the lower end in dedusting chamber 2, water conservancy diversion centrum 6 is cone, and dedusting chamber 2 and the top, junction of water conservancy diversion centrum 6 are provided with tangential injection system 5, and the lower end of water conservancy diversion centrum 6 is connected with gravity ash discharging mechanism 7.Gravity ash discharging mechanism 7 lower end is lower ash silo centrum 8 and ash discharging mechanism 9.Gravity ash discharging mechanism 7, lower ash silo centrum 8 and ash discharging mechanism 9 are arranged with one heart.
As shown in Figure 2: tangential injection system 5 comprises tangential winding-up air inlet 11, water sucking mouth 12, tangential winding-up exhaust outlet 13, trunnion 14, described trunnion 14 connects tangential winding-up air inlet 11 and tangential winding-up exhaust outlet 13, trunnion 14 stays an aperture, the water sucking mouth 12 of access suction pipe shape.
The utility model in use, flue gas enters dedusting chamber 2 with certain intake velocity by air inlet 3, 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 the centrifugal force produced in strong rotary course gets rid of to wall, grit once contact with wall, just lose inertia force and by entrance velocity produce momentum and self gravity along the water conservancy diversion on wall catch drip screw mechanism 4 fall enter water conservancy diversion centrum 6 bottom.Rotate the air-flow that declines at the bottom of the cone arriving water conservancy diversion centrum 6 after, axis part along deduster is transferred upwards, form the interior rotational gas flow risen, remain less grit by tangential injection system 5, 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 large, or accelerate collision with the grit of other water contents and combine, form larger particle and caught by water conservancy diversion again and drip a screw mechanism 4 and to lead water conservancy diversion centrum 6 bottom.The dust arriving gravity ash discharging mechanism 7 is collected owing to falling into ash discharging mechanism 9 again after Action of Gravity Field enters lower ash silo centrum 8, and final purification gas rises in deduster central axis, and is discharged by the exhaust outlet 1 of deduster.
Tangential injection system 5 is when acting on, a small amount of flue gas enters system by air inlet 11 of tangentially jetting, flue gas flow velocity when entering trunnion 14 position narrowed suddenly becomes large, there is vacuum state, a small amount of water is sucked trunnion 14 by water sucking mouth 12 by vacuum, spray with the form of water smoke exhaust outlet 13 of tangentially being jetted under the high speed pressure of flue gas, enter dedusting chamber 2.
The inwall in dedusting chamber is also provided with multiple sensor 10, it can detect in air outlet that parameter transmission such as flowing through flue-gas temperature, humidity, dust content is to control system, after the flow velocity access to plant of flue gas slight drag, tangential injection system 5 carries out winding-up acceleration, 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 parameter such as temperature, humidity, dust content of flue gas 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 and is dripped the effect that screw mechanism 4 had both played water conservancy diversion, has subtracted again the splashing of dust, has also trapped water droplet simultaneously, thus reached the object of water-dust removing.
Above an embodiment of utility model has been described in detail, but institute's content is only the utility model preferred embodiment can not be considered to for limiting the utility model practical range.All equalizations done according to the utility model application range change and improve, and still all should belong to patent covering scope of the present utility model.
