Description
Technical field
Detection sampler in being produced the utility model is related to a kind of vinyl chloride converter, especially to converter outlet
Gas detection sampler.
Background technology
Currently, well known VCM synthesis technology is very ripe, technical process is：The second sent from acetylene workshop
Alkynes gas and the hydrogen chloride gas sent from hydrochloric acid section, are sufficiently mixed in a mixer by certain molecular proportion, using
Gaseous mixture cooler and gaseous mixture demister, further cooled dehydrated, after the preheated device preheating of dewatered gaseous mixture, to one,
Two groups of converter reactions, are converted to thick vinyl chloride gas, for thick vinyl chloride gas through demercuration device demercuration, thick vinyl chloride cooler is cold
But, excessive hydrogen chloride gas and a small amount of carbon dioxide gas are removed using combined column, water scrubber and caustic wash tower, is sent to compression
Post.
One, it needs to sample vinyl chloride gas at converter outlet and detect after two groups of converter reactions, which takes
Due to the requirement of actual production Indexs measure more frequently, daily converter sampling and the detection frequency are every 2 hours one to sample
It is secondary, it requires more to detect the frequency because producing exception sometimes.It is primarily present following problem at present：
1, one, two group of converter is that the blowdown valve taken over from converter outlet goes out mostly to vinyl chloride gas sample position
Mouth sample detection, acid is easily deposited at sewage draining exit, therefore sewage draining exit takes and contains a large amount of hydrogen chloride in tested gas sample, to being taken
The accuracy of sample is influenced；
2, it is sampling bladders to commonly use sampler, and mouth is larger compared with handle and acid is easily deposited in frequent sampling, inside, and not easy to clean,
There is serious corrosivity to sampling bladders, so replacing frequent；
3, because frequently sampling, continually switching sewage draining valve, the corrosion and loss to sewage draining valve are also very big, and converter
Mostly tens or even up to a hundred, and vinyl chloride gas is inflammable and explosive, leaked gas may be made when frequently replacing sewage draining valve
At environmental protection and the uncertainty of safety, the generation of safety and environmentally friendly accident can be caused when serious, while increasing replacement valve
And the cost consumption of sampling appliance.
Invention content
The utility model technology be designed to provide it is a kind of it is easy to operate, sampler can be cleaned in real time, be conducive to safety behaviour
Make a kind of vinyl chloride converter gas detection sampler with environmental protection production, increase sampling accuracy.
In order to achieve the above object, the utility model proposes a kind of vinyl chloride converter gas detection samplers, if
It is placed in converter outlet and takes over middle and lower part, which includes：Nipple, hand valve, double end is followed successively by from left to right to take over, is interior
Seal gasket, gland, external seal rubber cushion, hand valve left end are connect with nipple by screw threads for fastening, and hand valve right end is taken over double end
Left end is connected by screw threads for fastening, after double end take over right-side outlet end through hole compresses sealing placement by interior sealing rubber cushion, then will
Gland compresses interior sealing rubber cushion and is connected with double end take over screw threads for fastening, and at gland outlet through hole, external seal rubber cushion is placed
It compresses.
The nipple, is set to the sampler leftmost side, and nipple left end is taken over middle and lower part position with converter outlet and welded
It connects, right end band external screw thread is fastened and connected with hand valve internal thread；
The hand valve is set on the right side of nipple, and hand valve left end is connect with nipple by screw threads for fastening, hand valve right end and
Double end is taken over to be connected by screw threads for fastening；
The double end is taken over, and is set on the right side of hand valve, and double end take over left end is connect with hand valve by screw threads for fastening, and double end connects
After the sealing of interior sealing rubber cushion is placed at pipe right-side outlet end, it is connect by screw threads for fastening with gland；
The interior sealing rubber cushion is set to double end and takes on the right side of outlet end, after sealing is placed, interior sealing rubber cushion protruding parts
It is closely connected with gland inner via hole, and after being compressed by gland, then is taken over double end by gland and connect by screw threads for fastening；
The gland is set to double end and takes on the right side of outlet end, after compressing interior sealing rubber cushion inside gland, connect with double end
Pipe is connected by screw threads for fastening；
The external seal rubber cushion is set on the right side of gland outlet end, gland right end through-hole and external seal rubber cushion protruding parts
It is closely connected.
Above-mentioned interior sealing rubber cushion uses antiseptic rubber, interior sealing rubber cushion convex with external seal rubber cushion with external seal rubber cushion material
Go out position outer diameter to be closely connected with gland outlet through hole internal diameter.
Above-mentioned double end, which takes over upper and lower surface at the tube wall of outside, rectangular platform, and clamping is facilitated to dismount.
Above-mentioned hand valve uses corrosion-resistant hand valve.
Because of a kind of vinyl chloride converter gas detection sampler provided by the utility model, by former one, two group of conversion
Vinyl chloride gas sample position in device, the blowdown valve outlet taken over by converter outlet are changed to discharge connection tube wall middle and lower part,
And welding gas detects sampler, solves the problems, such as to sample easily deposition acid at sewage draining exit, solves because of hydrogen chloride deposition pair
The influence of accuracy；Using this gas detection sampler, syringe sampling of arranging in pairs or groups is solved with bladders is sampled, and mouth is compared with handle
The problem of acid is easily deposited in larger and frequent sampling, inside, and not easy to clean；Interior sealing rubber cushion is compressed using gland, external seal is used in combination
Rubber cushion carries out double-layer seal again, while using corrosion-resistant hand valve, because interior sealing rubber cushion, external seal rubber cushion carried out it is double-deck close
Envelope can not have to often close hand valve, reduce the replacement number of valve, reduce the cost consumption of sampling appliance, to shut out
The accident potential of environmental protection and safety may be caused absolutely, and the utility model also solves and mitigates labor intensity, optimization
Production process can be widely used for mating gas detection sampler in different operating modes productions.
