Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 1:
As shown in Figures 1 to 8, 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 reactor bearing 1, the upper and lower side of reactor 1 is equipped with charging aperture, connected 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, lower end is coaxially installed with two guide shells 4, fluid impingement zone IZ is formed between the outlet of guide shell, the screw 6 that two rotation directions are contrary is coaxially arranged with in guide shell 4, be respectively used to propelling fluid flow to fluid impingement zone IZ from top and bottom through guide shell 4, in order to strengthen knockout process, the inwall of each guide shell is provided with spiral diversion sheet 7.
The course of work of the present invention is: the rotation of two screws 6, drive reactor 3 inner fluid respectively from upper, the charging aperture turn of lower end enters guide shell 4, act on because the fluid near guide shell 4 inwall is subject to spiral diversion sheet 7, hinder fluid longitudinal flow, fluid flow line is bent and flowing oblique, and guide it to rotate outflow guide shell 4, clash in opposite directions at impingement region IZ, then the fluid flowed out from impingement region IZ is by turning back to the region between screw 6 and reactor 3 end between guide shell 4 outer wall and reactor 3 inwall, simultaneously, in entering of guide shell 4, exit region, because the turnover of whirl fluid is entrainmented and blending along with strong, the flow direction of fluid is: from the import of guide shell to guide shell inside spin again to impingement region IZ, fluid after impingement region IZ clashes into arrives between guide shell outer wall and inside reactor again, arrive the import of guide shell again, so circulate.
Through test, when the blade inclination alpha of two screws is 15 ° ~ 60 °, can the mixed performance of enhance fluid and circulation ability further.In order to increase impact of the present invention further, the hand of spiral of each spiral diversion sheet can be made identical with the hand of spiral of its corresponding screw.
