The utility model relates to liquefied ammonia chemical analysis technology field, particularly a kind of sampler that is applicable to that liquid ammonia quality is analyzed.
Background technology
Liquefied ammonia is a kind of important chemical product, can be widely used in industries such as medicine, chemical industry, also can be used as refrigerant like preparation nitric acid, ammonium salt, azanol etc. and use.Liquefied ammonia also is Hazardous Chemical Substances simultaneously, reaches at 15.7～27.7% o'clock with air mixed concentration, can blast. the sampling steel cylinders that adopt are taken a sample more when its each item technical indicator is analyzed.Detailed process is following: the liquid phase valve of the steel cylinder of at first will taking a sample is opened, and emits a part of liquefied ammonia earlier, discards, and takes a sample according to certain sample rate again.In the sampling process,, therefore certain pollution can be brought, also certain injury can be brought to the sample collector simultaneously surrounding environment owing to need earlier a part of liquefied ammonia to be discharged in the air.In addition, liquefied ammonia directly is discharged in the air, also has the danger of blast with air mixed.Simultaneously owing to can contain some impurity such as oil, sulphur, iron and water in the liquefied ammonia product; The sampling steel cylinder uses for a long time, and these impurity can be deposited on the bottom and sidewall of sampling steel cylinder, because the sampling steel cylinder can't clean; Do not observe simultaneously the pollution condition in the sampling steel cylinder yet; Therefore can have pollutant in various degree in the liquefied ammonia sample of using the sampling steel cylinder to get, bring certain error can for like this quality analysis work of liquefied ammonia, can't provide and analyze data accurately
The utility model content
The purpose of the utility model is: a kind of sampler that liquefied ammonia is analyzed that is used for is provided, and simple to operation, safe and reliable, be used for the sampler that liquefied ammonia is analyzed.
The technical scheme that the utility model adopts is: be used for the sampler that liquefied ammonia is analyzed, be used for the sampler that liquefied ammonia is analyzed, comprise a drum; It is characterized in that: transparent sampling jar, transparent first absorption bottle and transparent second absorption bottle are arranged in the drum; A liquefied ammonia input pipe is arranged on the said sampling jar lid, and first absorption bottle is connected with sampling jar respectively through pipeline with second absorption bottle, and the first absorption bottle lid is provided with first delivery pipe; The second absorption bottle lid is provided with second delivery pipe; On the first absorption bottle lid pipeline is arranged, the upper end of pipeline is connected with the 3rd connector, can pipeline linked to each other with the liquefied ammonia input pipe through the 3rd connector; The upper end of liquefied ammonia input vertical tube is connected with second by-pass valve control, and the other end of second by-pass valve control is connected with second connector through pipeline; Be connected with the 4th by-pass valve control on the liquefied ammonia input pipe, the other end of the 4th by-pass valve control is connected with first connector through pipeline, and first connector, second connector and the 3rd connector are same bore, can be tightly connected each other.
On first absorption bottle, sampling jar and the second absorption bottle wall scale is arranged, be convenient to metering.
Above-mentioned drum is the double-layer stainless steel drum.
The observation panel that an ability switch is arranged on the above-mentioned drum wall.
Summary is used for the use of the sampler of liquefied ammonia analysis.Consult Fig. 1.When needing sampling; At first with first absorption bottle 1; The sampling jar 2 and second absorption bottle 3 are put into drum 11; All first by-pass valve controls 4, second by-pass valve control 5, the 3rd by-pass valve control 6 and the 4th by-pass valve control 18 are in closed condition, and first connector 9, second connector 10 and the 3rd connector 13 are in off-state.Earlier the 3rd connector 13 on first absorption bottle 1 is connected with first connector 9 on the liquefied ammonia input pipe 17, opens the 4th operation valve 18, the liquefied ammonia in the liquefied ammonia pipeline 12 is by 1 absorption of first absorption bottle.Effect is through discharging liquefied ammonia, the cleaning before liquefied ammonia pipeline 12 is taken a sample.The cleaning situation of observing the liquefied ammonia pipelines through observation panel 14 that can switch on the drum 11.After discharging about 1～2 minute, liquefied ammonia pipeline 12 cleans and finishes.Close the 4th operation valve 18 on the liquefied ammonia input pipe 17, first connector 9 and the 3rd connector 13 are broken off.Then first connector 9 is connected with second connector 10 on the liquefied ammonia input pipe 15, opens second operation valve 5 earlier, open the 4th operation valve 18 again, the liquefied ammonia product in the liquefied ammonia pipeline 12 is discharged in the sampling jar 2 through liquefied ammonia input pipe 15, begins to take a sample.Sampling is closed the 4th by-pass valve control 18 earlier after finishing, and closes second by-pass valve control 5 again, and first connector 9 and second connector 10 are broken off, and sampling finishes.Sample in being sent to the process of analysis, with on first absorption bottle 1 the 3rd by-pass valve control 6 and first by-pass valve control 4 on second absorption bottle 3 open, be used for absorbing the liquefied ammonia of volatilization in the sampling jar 2, prevent that the sampling jar internal cause is full of a large amount of gases and blasts.Drum 11 plays protective action, and blast in being sent to the process of analysis the liquefied ammonia sample by sampling jar when possible, drum 11 can prevent the fragment of sampling jar splash around and hurt sampling personnel and other people.
The beneficial effect of the utility model: the utility model is used for the sampler that liquefied ammonia is analyzed; Be applicable to sample taps such as pipeline, tank car; Also can realize simultaneously the sampling process of other poisonous and harmful volatile liquids, whole sampling process can realize through controlled valve and switching connector.Sampling process is simple to operate, and is safe, and sample rate is fast, and it is high to analyze the data accuracy, has improved work efficiency greatly.
When cleaning the liquefied ammonia pipeline in the sampling process; The absorption liquid that liquefied ammonia directly is absorbed in the bottle absorbs; Observe the cleaning situation of liquefied ammonia pipeline through observation panel that can switch, and need liquefied ammonia is not in line in atmosphere, both can avoid polluting surrounding environment; Can prevent again in the air that ammonia concentration is excessive and blast, guarantee sampling personnel's personal safety.Transparent sampling jar can be observed sampling jar by the pollution level of liquefied ammonia sample, and convenient the cleaning, has reduced because of the contaminated error of bringing to analytic process of sampling jar.After sampling finished, in transit, the liquefied ammonia that volatilizees in the sampling jar was absorbed by the absorption liquid in two absorption bottles, prevented owing to the liquefied ammonia volatilization makes the sampling jar internal pressure excessive the danger that causes sampling jar to blast.Both guaranteed to analyze promptly and accurately, stablized production again, improved economic benefit.
