Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.
Embodiment one
A kind of high sulfur naphtha desulfurization back-flow preventer as shown in Figure 1, including desulfurizing tower 1, surge tank 3, before the desulfurizing tower 1
End is equipped with inlet tube, and desulfurizing tower 1 is connected by pipeline one with surge tank 3, and pipeline one is equipped with check-valves 1, the surge tank 4
Upper end be equipped with exhaust pipe, exhaust pipe is equipped with check-valves 24, and it is connected that 3 upper end of surge tank is equipped with booster fan 5, described
3 bottom of surge tank is connected by pipeline two with the import of return tank 7, the phegma outlet 76 of return tank 7 pass through pipeline three and into
Liquid pipe is connected, and pipeline two is equipped with baffle 1, and pipeline three is equipped with baffle 28.
Specifically, the booster fan 5 uses Silence Process axial flow blower.
Specifically, the baffle 1, baffle 28 are using pneumatic double blinds sealing baffles.
Specifically, it is equipped with pressure gauge one positioned at the preceding of check-valves 1 on the pipeline one, is equipped with pressure gauge in surge tank
Two, check-valves 24 is located on exhaust pipe and is equipped with pressure gauge two, pressure gauge one, pressure gauge two, pressure gauge three and control system below
