Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As depicted in figs. 1 and 2, the gas solid separation of the present embodiment comprises by end socket 10 with integrated two stage cyclone separator, the can that cylindrical shell 7 and cone 2 are connected to form, cylindrical shell 7 is provided with air inlet 4 and exhaust outlet 12, upper spacer 13 and lower clapboard 15 is provided with in cylindrical shell 7, air inlet 4 is positioned at the below of lower clapboard 15 and layout tangent with cylindrical shell 7, exhaust outlet 12 is located at the upside of upper spacer 13, multiple cyclone separator 14 be arranged in juxtaposition is provided with between upper spacer 13 and lower clapboard 15, the downside of cyclone separator 14 is provided with interior reservoir ash bucket 16, gap is provided with between the inwall of interior reservoir ash bucket 16 and cylindrical shell 7, interior reservoir ash bucket 16 by two spin material legs 17 be fixed on two in cone 2 and revolve discharge gate 18 and be communicated with, the bottom of cone 2 is provided with one and revolves discharge gate 1.The present embodiment operationally, dusty gas is entered by air inlet 4, because air inlet 4 and cylindrical shell 7 are tangent, gas produces in cylindrical shell 7 inside subsequently and rotates, gas can produce centrifugal force when High Rotation Speed, due to centrifugal action, dust gets rid of and fall into cone 2 on cylinder inboard wall and because of gravity, and then revolves discharge gate 1 by one and discharged by dust.This by air inlet 1 and cylindrical shell 7 tangent and and cone 2 together constitute first order cyclone separator, 80 ~ 90% solid particles (being particularly greater than the particle of 30 μm) can be separated by this first order cyclone separator, significantly reduce the load of later separation device.But because the restriction of first order cyclone separator structure and diameter are comparatively large, this first order cyclone separator is for the separating effect of fine grained (as being less than the particle of 20 μm) or poor.Dust-contained airflow enters several cyclone separators 14 by the annular gap between cylindrical shell 7 and interior reservoir ash bucket 16 subsequently, dusty gas enters from the whirlwind air inlet 145 of each cyclone separator 14 respectively, whirlwind air inlet 145 have employed special-shaped import, namely import cross section is the trapezoidal of gradual change, due to centrifugal action, dust gets rid of to wall and falls into middle ash bucket 142 because of gravity, dust enters interior reservoir ash bucket 16 by sewage draining exit 141, revolves discharge gate 18 discharged by dust finally by two spin material legs 17 from two; Gas now through purified treatment flows out through exhaust pipe assembly 146, purified gas is flowed out by exhaust outlet 12 eventually through the space on upper spacer 13 top, and due to the second level cyclone separator that is jointly made up of several cyclone separators 14 because its diameter is little and have the structure of the elimination to the main secondary vortex flow of whirlwind, thus good separating effect is had to fine grained (as being less than the particle of 20 μm), be applicable to the working condition that gas dust content is high, fine particle content is more, resistance is low and need separative efficiency high.
In the present embodiment, interior reservoir ash bucket 16 be welded and fixed with cylindrical shell 7 by fixing gusset 5.
In the present embodiment, upper spacer 13 and lower clapboard 15 offer several circular holes matched, and the upper and lower port of cyclone separator 14 is welded and fixed respectively by above-mentioned circular hole and upper spacer 13 and lower clapboard 15.
In the present embodiment, cone 2 is provided with cone hand hole 3.
In the present embodiment, outer wall cylindrical shell 7 is positioned on the upside of upper spacer 13 is provided with cylindrical shell hand hole 8.
In the present embodiment, the top of end socket 10 is provided with manhole 11.
In the present embodiment, the top of cylindrical shell 7 is provided with hanger 9.
In the present embodiment, the sidewall of cylindrical shell 7 is provided with ear seat 6.
As shown in Figure 3, cyclone separator 14 comprises the sewage draining exit 141, middle ash bucket 142, cone 143 and the Whirlwind barrel 144 that are connected successively from the bottom up, the sidewall of Whirlwind barrel 144 is provided with two whirlwind air inlets 145, and the upper end of Whirlwind barrel 144 is provided with exhaust pipe assembly 146.
As shown in Figure 3, the cross section of whirlwind air inlet 145 is trapezoidal, and the inner side being positioned at whirlwind air inlet 145 in Whirlwind barrel 144 is provided with water conservancy diversion arc; Exhaust pipe assembly 146 is by the sheathed double-decker formed of pipe cone in outer blast pipe and exhaust, and in exhaust, pipe cone is provided with several trapezoidal slotted eyes.In the present embodiment, cyclone separator 14 is a kind of efficient cyclone separators with double in-and outlet, can prove that the whirlwind (being often referred to whirlwind internal diameter at below 300mm) of minor diameter has larger advantage to fine grain separation in theory; Simultaneously cyclone separator 14 have employed two special-shaped import (sidewall of Whirlwind barrel 144 is provided with two whirlwind air inlets 145, the cross section of whirlwind air inlet 145 is trapezoidal) the gradual shrinkage flow-guiding type import that forms with water conservancy diversion arc, water conservancy diversion arc and Whirlwind barrel 144 top are provided with a gap, and this structure makes whirlwind air inlet 145 air flow method rule meet semi-free vortex (V
θ/ r=Const), namely impel the circular motion that inlet air flow tends to stable, the outer gas flow produced near wall can be avoided so inwardly to flow, prevent retardance dust granules to flow to blast pipe, greatly weaken " longitudinal bumpy flow ", be conducive to the raising of separative efficiency.Secondly the cyclone separator 14 of the present embodiment have employed the exhaust pipe assembly 146 of inside and outside double-decker (in outer blast pipe+exhaust pipe cone), in exhaust, pipe cone is provided with several trapezoidal slotted eyes, shown by the research of cyclone separator 14 flow field and concentration field, " upper eddy current (or title short-circuit flow) " mainly concentrates on the lower area of exhaust pipe assembly 146, in the exhaust of the present embodiment internal layer, the lower port diameter of pipe cone is programmable compared with other whirlwind less, reason is that trapezoidal slotted eye increases the effective area of blast pipe and reduces whirlwind resistance, outer blast pipe provides protection and rectified action to internal layer blast pipe simultaneously, so " upper eddy current (or claiming short-circuit flow) " also greatly reduces the efficiency impact of this structural shape, thus cyclone separator 14 can be made to affect the main secondary vortex flow of whirlwind efficiency for two all accomplished to eliminate as much as possible.
