Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the swirl flow gas-liquid separator that the utility model provides, it comprise separable cartridge 1, blast pipe 2, dividing plate 3, transition chamber 4, riser 5, discharge opeing annular space 6, spin-ended 7, main disengagement chamber 8, liquid pool 9, liquid-phase outlet 10, mixed phase inlet tube 11, return duct 12 and deflection plate 13.The top of separable cartridge 1 arranges blast pipe 2, and the upper end of blast pipe 2 is communicated with outside, and the lower end of blast pipe 2 extends to separable cartridge 1 inside.Separable cartridge 1 internal upper part arranges dividing plate 3, forms transition chamber 4 between separable cartridge 1 top and dividing plate 3, and the center of dividing plate 3 wears fixing riser 5, the axis of riser 5 and the dead in line of separable cartridge 1.Riser 5 diameter is greater than blast pipe 2 diameter, and the top of riser 5, just to the bottom of blast pipe 2, exists discharge opeing annular space 6 between riser 5 and blast pipe 2.The bottom of separable cartridge 1 is fixedly installed spin-ended 7, main disengagement chamber 8 is formed between spin-ended 7 and dividing plate 3, the main disengagement chamber 8 axle center place be positioned at above spin-ended 7 arranges deflection plate 13, and spin-ended 7 forms liquid pool 9 with the bottom of separable cartridge 1, and the bottom of separable cartridge 1 arranges liquid-phase outlet 10.The top of separable cartridge 1 is communicated with the mixed phase inlet tube 11 being arranged on separable cartridge 1 outside.Return duct 12 is arranged on the outside of separable cartridge 1, and the upper port of return duct 12 is communicated with transition chamber 4, and the lower port of return duct 12 is fixedly connected with deflection plate 13.Return duct 12 is arranged on the outside of separable cartridge 1, and the upper port of return duct 12 is communicated with transition chamber 4, and the lower port of return duct 12 is fixedly connected with deflection plate 13.
In a preferred embodiment, as shown in Figure 2, dividing plate 3 can adopt inclined plane towards the end face of transition chamber 4, and inclined plane points to the upper port of return duct 12, thus ensure the liquid being entered transition chamber 4 in riser 5 by discharge opeing annular space 6, return duct 12 can be flowed into smoothly.
In a preferred embodiment, as shown in Figure 3, when the upper port of return duct 12 is communicated with transition chamber 4, the mode that dislocation connects can be adopted, namely the lower edge of the upper port of return duct 12 is a little less than the upper edge of dividing plate 3, once have liquid to produce in transition chamber 4, liquid just can flow to return duct 12 smoothly, thus avoids producing hydrops in transition chamber 4.
In a preferred embodiment, as shown in Figures 4 and 5, deflection plate 13 can adopt conical plate, and the cone angle of conical plate is towards the lower port of riser 5, and the basal diameter of conical plate is less than the internal diameter of separable cartridge 1.The conical surface of conical plate provides a radially outer weight component to drop attached to it, in order to balance the drag force impetus of this place's radial air flow, avoids the liquid film be separated by secondary droplets.During work, due to cyclonic action, between transition chamber 4 and deflection plate 13, form positive pressure difference, thus the liquid be forced through in riser 5 enters transition chamber 4 from discharge opeing annular space 6.Enter liquid in transition chamber 4 by after return duct 12, be discharged on main disengagement chamber 8 inwall by the port of deflection plate 13, and flow back to liquid pool 9.
In a preferred embodiment, as shown in Figure 6, spin-ended 7, for further stablizing the liquid entering liquid pool 9, prevents fluctuation and high-speed rotational the entrainmenting liquid of liquid level, it can adopt the rectangular tab of right-angled intersection, and right-angled intersection rectangular tab and separable cartridge 1 inwall are fixed.
The concrete use procedure of the swirl flow gas-liquid separator that the utility model provides is:
Gas-liquid mixed phase flows through and enters separable cartridge 1 by mixed phase inlet tube 11, the major part in gas-liquid mixed phase stream dissociate liquid film can under gravity along main disengagement chamber 8 inwall enter bottom liquid pool 9.The drop that Action of Gravity Field fails to be separated in time, producing rotary motion by the annular space between main disengagement chamber 8 inwall and riser 5 outer wall and the space between riser 5 lower port and deflection plate 13, is completed the separation of droplet by centrifugal force.
Through main disengagement chamber 8 except the air-flow after liquid is when entering riser 5 and moving upward, because flow area diminishes, eddy flow more at a high speed and stronger centrifugal force is formed in riser 5, riser 5 inwall is thrown to by remaining the less drop of particle diameter in air-flow, liquid film is formed at riser 5 inwall, and migrate under the effect of riser 5 inwall axial shearing stress and climb, discharge opeing annular space 6 through being arranged in riser 5 top enters separator transition chamber 4, because dividing plate 3 end face is inclined plane, the liquid phase entering transition chamber 4 has flowed to return duct 12 upper port smoothly, the mode adopting dislocation to connect due to return duct 12 upper port is communicated with transition chamber 4, the liquid phase that ensure that in transition chamber 4 is not formed to be gathered, thus enter return duct 12 smoothly.The liquid phase entering return duct 12 sprays to main disengagement chamber 8 inwall from deflection plate 13 port connecting return duct 12 lower end, the conical design of deflection plate 13 provides a radially outer weight component to drop attached to it, in order to balance the drag force impetus of this place's radial air flow, avoid the liquid film be separated by secondary droplets.The liquid phase of main disengagement chamber 8 inwall flows to liquid pool 9 through spin-ended 7 under gravity, complete the separation again of escape drop, adopt the rectangular tab of right-angled intersection for spin-ended 7, the liquid phase being separated to liquid pool 9 is further stablized, prevent high-speed rotational from causing the fluctuation of liquid level and entrainmenting liquid phase, the liquid phase in liquid pool 9 flows out separable cartridge 1 eventually through liquid-phase outlet 10.
The various embodiments described above are only for illustration of the utility model; wherein the structure of each parts, connected mode and manufacture craft etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
