The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Embodiment 1:
Extremely shown in Figure 8 such as Fig. 1, a kind of impact flow reactor, it is vertical structure, it comprises reactor bearing 1, barrel type reactor 3, feed pipe 2, blast pipe 5, discharge duct 8, guide shell 4, spiral diversion sheet 7 and screw 6, reactor 3 is fixed on the reactor bearing 1, the upper and lower side of reactor 1 is equipped with charging aperture, connect by feed pipe 2, described discharge duct 8 is installed in the lower end of reactor 1, described blast pipe 5 is arranged on the upper end of reactor 3, upper in the inside of reactor 3, the lower end is coaxially installed with two guide shells 4, between the outlet of guide shell, form fluid impact zone IZ, in guide shell 4, be coaxially arranged with two screws 6 that rotation direction is opposite, being respectively applied to propelling fluid flows to fluid impact zone IZ from top and bottom through guide shell 4, in order to strengthen knockout process, be provided with spiral diversion sheet 7 at the inwall of each guide shell.
The course of work of the present invention is: the rotation of two screws 6, drive reactor 3 inner fluids respectively from upper, the charging aperture turn of lower end enters guide shell 4, because near the fluid guide shell 4 inwalls is subject to 7 effects of spiral diversion sheet, hinder the fluid longitudinal flow, make the crooked and oblique that flows of fluid flow line, and guide its rotation to flow out guide shell 4, IZ clashes in opposite directions at impingement region, then the fluid that flows out from impingement region IZ is by turning back to the zone between screw 6 and reactor 3 ends between guide shell 4 outer walls and reactor 3 inwalls, simultaneously, in advancing of guide shell 4, exit region, because the turnover of whirl fluid is accompanied by strong entrainmenting and blending, the flow direction of fluid is: from the import of guide shell to the guide shell inside spin again to impingement region IZ, arrive again between guide shell outer wall and the inside reactor through the fluid behind the impingement region IZ bump, arrive again the import of guide shell, so circulate.
