Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.The present embodiment be take technical solutions of the utility model and is implemented as prerequisite, provided detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, a kind of piston type CO compressor packing device for HYCO factory, comprise the labyrinth ring group being arranged in order from high pressure side C to low voltage side D, radially/tangential ring group and nitrogen-sealed ring group, labyrinth ring group, radially/tangential ring group and nitrogen-sealed ring group are embedded successively in stuffing box 7, described radially/tangentially between ring group and nitrogen-sealed ring group, be provided with gas leakage recovery channel 5, piston rod 4 is located in labyrinth ring group, in radially/tangential ring group and nitrogen-sealed ring group, and move back and forth within it, CO flows in the gap of piston rod 4 and each ring group, the CO major part of leaking through above-mentioned six road ring groups will reclaim a mouthful B by gas leakage, being sent to torch burning falls.
Described labyrinth ring group comprises that 3, three labyrinth rings 3 of three labyrinth rings are embedded successively in stuffing box 7, and the side of each labyrinth ring is provided with retaining spring, and each labyrinth ring is adjacent on a sealing surface of stuffing box by described retaining spring.As shown in Figure 4, described labyrinth ring 3 is for also radially having the three-clove style labyrinth ring of three road back flashes with six retaining springs, and its internal diameter is bigger compared with diameter of piston rod.
Described radially/tangentially ring group comprise three radially/tangentially encircle 2, three radially/tangentially encircle 2 to be embedded in stuffing box successively.Radially/tangentially encircle 2 routines radially, tangential ring group, each radially/tangentially encircle in 2, radial ring is positioned at high pressure side, tangential ring is positioned at low voltage side.Described radially/tangential ring for three-clove style radially/tangential ring, as shown in Figure 3.
Described nitrogen-sealed ring group comprise from high pressure side to low voltage side be embedded successively labyrinth ring 3 in stuffing box and one tangential/tangentially encircle 1, described tangential/tangentially encircle a side of 1 to be provided with retaining spring.Described labyrinth ring 3 and tangential/tangentially encircle 1 to be connected with nitrogen blanketing valve road 6, passes into nitrogen by filling nitrogen mouth A.Nitrogen enters in the middle of two groups of rings.Most nitrogen passes through on high-tension side labyrinth ring, and goes to torch after the CO leaking mixing.Because the pressure of nitrogen is higher than leaking the pressure of CO and the back pressure of torch, so CO cannot leak toward left side by labyrinth ring conversely in theory.A small amount of nitrogen leaks in middle body by tangential/tangential ring group of the leftmost side.Like this, just guaranteed safety in production.
The effect of on high-tension side three road labyrinth rings is expenditure and pressures, side retaining spring can make labyrinth ring another side be adjacent to all the time on a sealing surface of stuffing box, and can be with piston rod to-and-fro motion between two sealing surfaces of this ring place stuffing box vibration back and forth.High pressure CO can only be along the gap between labyrinth ring and piston rod toward external leakage like this, in theory.Due to the expenditure and pressure effect in labyrinth, only have a small amount of high pressure CO by three road labyrinth rings, its pressure also greatly reduces.
Middle San road radially/tangential ring is real CO seal ring.Yao San road labyrinth ring why before, main object is decompression, prevent by the CO pressure of leak into radially/tangential ring of labyrinth ring too high because this pressure will put on the periphery of tangential ring.This pressure is larger, and tangential ring is larger to the enclasping force of piston rod, and frictional force is between the two just larger, and the surface temperature of piston rod is just higher.
Because inflammable, the explosive and hypertoxic characteristic of CO, in the low voltage side of filler, be provided with nitrogen-sealed ring group, between two groups of rings, be filled with the nitrogen of 1.5barg.No matter how filler designs, and always have a small amount of CO and leak in middle body by each road seal ring group, and along with the increase of packing ring wear extent, leakage rate is also along with increase.Toward the nitrogen being filled with in filler, can stop on the one hand the CO that major part is leaked by seal ring to leak to middle body, most CO is burnt by the recovery line of the leaking gas torch that reduces internal heat; The nitrogen of part leaks to middle body, the concentration of CO in body in reduction on the other hand.The mixed gas of this part nitrogen and CO also will be burnt towards torch.Why one group of two groups of nitrogen-sealed rings adopts labyrinth ring, is in order to prevent from forming between two groups of rings the constant voltage cavity of similar sealing.The nitrogen pressure of 1.5barg acts on the periphery of tangential ring, to make tangential ring produce larger enclasping force to piston rod, piston rod surface will produce many heats, and nitrogen is heated, approximate airtight because of this cavity, the temperature of nitrogen will be more and more higher, cause vicious circle: nitrogen temperature is more and more higher, piston rod surface temperature is more and more higher, finally causes carbon distribution.If a side has adopted labyrinth ring, although the use amount of nitrogen will increase, due to flowing of normal temperature nitrogen, will take away most frictional heat, prevent that piston rod from producing high temperature.
