Wherein, 500KW back pressure machine is in start process, steam not only a large amount of outlets, but also noise is very big；After unit normal operation,
Because axle envelope vapor extractor is still working, still there is about 0.3 ton of steam outlet per hour；For this purpose, Chinese Patent Application No.:
201220098231.7 disclosing a kind of recycling back pressure machine gland sealing steam exhaust, row's atmosphere steam trap connection；Its composition is in back pressure arbor
A steam water heat exchanger is increased in gland sealing steam exhaust system — that is, recycles the device of axle envelope row's atmospheric vapor；In back pressure machine startup-shutdown
Pipeline is separated on row's atmosphere drain pipe；Increase by four valves, then back pressure machine is arranged into atmosphere drain recovery to storage tank with main pipe；The dress
It sets and is made of recycling back pressure machine axle envelope row atmospheric vapor, recycling back pressure machine row's hydrophobic two parts of atmosphere, this two part passes through storage tank
It is connected；The utility model can also be such that steam and water is sufficiently mixed under a relatively high pressure, play stirring to liquid and follow
Ring acts on, and the temperature in storage tank can be consistent, and will not generate thermal stratification；Noise and vibration are preferably minimized simultaneously；But
It is only to handle in line atmosphere, and there are packing leakages for the dragging back pressure machine of workshop high-temperature water heat circulation pump
Vapour, throttle and main inlet throttle-stop valve door rod leak vapour, cause very big energy loss and indoor environmental pollution.
Utility model content
In order to solve the above problems, the utility model proposes, and a kind of back pressure machine packing aspirates recyclable device, using in water tank
Condensed water by nozzle project, high-velocity flow volume inhale leakage vapour collecting pipe in each air leakage point steam and and in mixing chamber into
Row mixing is latter to enter back into water tank with being discharged into diffuser, gland leak-off and door rod leakage vapour can all be recycled in this way.
The back pressure machine packing of the utility model aspirates recyclable device, including water tank, and is installed on the water inlet filter on the inside of water tank
Cover；Water inlet pipe is installed on the water inlet filter bowl；The water inlet pipe is connected to nozzle by force (forcing) pump；The nozzle is through leakage
Vapour collecting pipe top；Extraction opening is connected to by air exhauster at the top of the leakage vapour collecting pipe；The leakage vapour collects bottom of the tube connection
To mixing chamber；The mixing chamber bottom is equipped with diffuser；The diffuser output end is connected to water tank；The extraction opening difference
It is set to packing, throttle and/or main inlet throttle-stop valve door rod air leakage point.
As preferred embodiment, each extraction opening is connected to air exhauster by steam pipe.
As preferred embodiment, it is provided with insulating layer outside the steam pipe, can reduce steam thermal energy loss.
As preferred embodiment, the water tank is provided with water compensating valve and outlet valve, and water compensating valve can supplement new water, out
Water valve can send out the water for completing heat exchange and carry out secondary use.
As preferred embodiment, the extraction opening is open cover structure or closed pipe structure.
Compared with prior art, the back pressure machine packing of the utility model aspirates recyclable device；Utilize water
Condensed water in case is projected by nozzle, and high-velocity flow volume inhales the steam for leaking each air leakage point in vapour collecting pipe and in mixing chamber
Inside carry out mixing it is latter enter back into water tank with being discharged into diffuser, gland leak-off and door rod leakage vapour can all be recycled in this way.
