Background technology
The cyclone separator of now general axial admission is by guider, separator tube, compositions such as blast pipe and ash bucket.The coaxial top that is deep in the separator tube of exhaust pipe lower part, be the coaxial guider that is installed on the blast pipe between blast pipe and the separator tube, the runner that the formation of several along the circumferential direction evenly distributed guide vanes and separator tube inwall turns to air-flow above the guider.The bottom sealing of separator tube is installed in the ash bucket.Ubiquitous problem is that cyclone separator exports local regional gas stream and has pulsation of high turbulent flow and strong secondary vortices motion phenomenon in the commercial Application process, cause the cyclone separator operating flexibility poor thus, pressure drop is big, and the energy consumption height has seriously hindered the energy efficiency of enterprise.
The utility model content
The technical problems to be solved in the utility model provides a kind of separative efficiency height, pressure drop is little, energy consumption the is low cyclone separator that has the orifice plate exhaust structure.
A kind of cyclone separator that has the orifice plate exhaust structure of the utility model comprises guider, separator tube and blast pipe, and the blast pipe lower port is provided with the orifice plate that is connected as a single entity, and is provided with aperture on orifice plate uniformly; The separator tube lower end is provided with the circular arc awl section that is connected as a single entity.
A kind of cyclone separator that has the orifice plate exhaust structure of the utility model, its aperture plate height are 0.05～4 times of blast pipe internal diameter; The cross sectional shape of opening aperture on the orifice plate is circular, square and oval; The angle θ of aperture is 0 °～45 °, and θ is the central axis of aperture and the angle between the blast pipe central axis; The aperture gross area is 30%～80% of a blast pipe internal diameter area.
A kind of cyclone separator that has the orifice plate exhaust structure of the utility model, wherein the height of circular arc awl section is 0.6～0.9 times of separator tube interior diameter; Arc radius is 1.3～1.6 times of separator tube interior diameter; Circular arc awl section lower port interior diameter is 0.5～0.7 times of separator tube interior diameter, is 0.9～1.2 times of blast pipe interior diameter.
A kind of advantage and good effect that has the cyclone separator of orifice plate exhaust structure of the utility model is: in blast pipe lower port installing hole plate structure, to become multiply by one from the air-flow that the blast pipe lower port enters according to the perforate number like this, strengthened high turbulent flow pulsation that exports local regional gas stream and the inhibition ability that strong secondary vortices is moved, reduced tornadotron pressure drop and energy consumption significantly; The variation of orifice plate perforated area and blowing angle can be regulated the interaction between the multiply air-flow, weakens the rotation function loss of air-flow in the blast pipe, further reduces the pressure drop of tornadotron; The orifice plate of blast pipe inlet reduces the exhaust circulation area, increased the spin intensity of air-flow in the tornadotron, has prolonged particle separated time in tornadotron, has improved the separative efficiency of tornadotron.
