The sampling device is suitable for being used in a positive-pressure and liquid-phase system in a chemical device, strong in sample reality, high in accuracy, free from the emissions of residual liquid and residual gas, capable of effectively preventing the harm of toxic and harmful mediums to an operator, and simultaneously free from environmental pollution and resource waste.
Description
Technical field
The utility model relates to a kind of sampler, is applicable to the closed sampling device in the on-the-spot reaction under high pressure process of chemical industry, belongs to chemical process and laboratory technical field of analysis and detection.
Background technology
Chemical Manufacture relies on sample analysis to do the guidance of production.How get safely and effectively sample and the correct check analysis that can reflect the true condition of production within a short period of time, is the important step in Chemical Manufacture.The most of production runes of chemical industry are courses of reaction of High Temperature High Pressure, and the sampling in course of reaction can in time reflect real reaction condition, make operating personnel can according to circumstances make fast corresponding adjusting.Yet the sampling in the reaction under high pressure process has suitable danger.At present, the chemical industry major part is directly directly opened on still the valve sampling to the scene with sampler, exists safety, the environmental issues such as volatilization, run, drip, leak of material smell in sampling process.
Existing sampling mode is that after autoclave row pressure cooling, sampling detects, this sampling mode has following shortcoming: 1. length consuming time: general reactor temperature of reaction＞120 ℃, pressure＞0.5MPa, its row pressure is cooled to 70 ℃, atmospheric pressure state takes a sample again, need a period of time, approximately 20-30min, add 5min sample time, 25-35min consuming time; If 2. testing result shows reaction not exclusively, need again increasing temperature and pressure to continue reaction, brought inconvenience to operation; Valve when 3. taking a sample on direct opening high pressure still gos deep into sampler to take a sample under feed liquid, although process through row pressure cooling, still has higher than the material gaseous volatilization of normal temperature out, and sampling personnel's safety is threatened; 4. sampler is taken a sample under feed liquid because going deep into, and after sampling finishes, has feed liquid and drips on sampler, causes the pollution of production scene.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel sampling device, to solve the above defective of existing sampling mode.This device construction is simple, and easy operating can guarantee operating personnel's safety and protection of the environment in sampling process.
The utility model is achieved through the following technical solutions:
A kind of sampler for autoclave comprises impact damper, and the impact damper bottom is provided with sample valve, and tensimeter and equalizing valve are established in top, and impact damper also is provided with material returning valve, inlet valve.
The sampling operation process is as follows:
Step (1): open bleeder valve and inlet valve, material returning valve, equalizing valve, sample valve, punishment in advance valve are in closed condition simultaneously.Reactor A internal pressure makes feed liquid be pressed into impact damper.Approximately close inlet valve after 1 minute, open equalizing valve and material returning valve, make the feed liquid in impact damper refund reactor A, 2～3 times so repeatedly.The purpose of this step is to displace gas and the remaining feed liquid of possibility in impact damper, guarantees to get sample really and accurately.
Step (2): after replacement completion, close material returning valve and equalizing valve, open inlet valve, make the feed liquid in reactor A enter impact damper through pipeline, during the close observation tensimeter.Approximately after 0.5～1 minute, close inlet valve, open sample valve, can begin sampling.
Step (3): after sampling finishes, close sample valve, open equalizing valve and material returning valve, can be under balance pipe air pressure with impact damper in remaining feed liquid push back reactor.Raffinate when this step both can have been avoided lower sub-sampling in impact damper affects the authenticity of sample, also can avoid raffinate Crystallization Plugging pipeline in the pipeline between impact damper and inlet valve.
Described sample valve is selected the stainless steel sample valve.
Described impact damper is jacket structured, prevents that feed liquid is at the impact damper intercrystalline; The impact damper top is provided with tensimeter, can truly reflect the impact damper internal pressure, can find in time with reactor A pressure comparison whether sampling process is processed extremely and in time.
The high, medium and low voltage liquid medium of the harmfulness such as the sampler that the utility model relates to is applicable in chemical plant installations malleation, liquid phase systems under the state of arts in pipeline, and is especially poisonous, inflammable, explosive without leaking sampling.The sample authenticity is strong, and accuracy is high, without raffinate, residual gas discharging.Prevent that effectively poisonous, hazardous medium is to operator's injury.Do not pollute the environment simultaneously, the peril of having avoided inflammable, explosive medium may cause when sampling.
The original sampling mode of the sampler that the utility model relates to and company compares, and have the following advantages: (1) sample has ageing, does not have dead sample, residual sample, and the sample of taking-up can accurately reflect real response situation; (2) shorten sample time, simple to operate, do not need decrease temperature and pressure to process; (3) if assay shows that reaction not exclusively, can continue reaction, can not increase operating personnel's repeated labor.Do not need sampler is goed deep in still environmental pollution and the wasting of resources that when having avoided sampling, the feed liquid drippage causes when (4) taking a sample.

Embodiment
As shown in Figure of description 1, the sampler that the utility model relates to comprises impact damper, charging and discharging valve, equalizing valve and sample valve.Inlet valve is communicated with autoclave and impact damper, and impact damper is jacket structured, and tensimeter and equalizing valve are established in top, and sample valve is established in the bottom, can be communicated with sampler.
During sampling, step (1): open bleeder valve 7 and inlet valve 6, material returning valve 1, equalizing valve 2, sample valve 5, punishment in advance valve 8 are in closed condition simultaneously.Reactor A internal pressure makes feed liquid be pressed into impact damper 4.Approximately close inlet valve 6 after 1 minute, open equalizing valve 2 and material returning valve 1, make the feed liquid in impact damper 4 refund reactor A, 2～3 times so repeatedly.The purpose of this step is to displace gas and the remaining feed liquid of possibility in impact damper, guarantees to get sample really and accurately.
Step (2): after replacement completion, close material returning valve 1 and equalizing valve 2, open inlet valve 6, make the feed liquid in reactor A enter impact damper 4 through pipeline, during close observation 3-tensimeter.Approximately after 0.5～1 minute, close inlet valve 6, open sample valve 5, can begin sampling.
Sampling is closed sample valve 5 after finishing, and opens equalizing valve 2 and material returning valve 1, can under balance pipe air pressure, the interior remaining feed liquid of impact damper 4 be pushed back reactor A.Raffinate when this step both can have been avoided lower sub-sampling in impact damper affects the authenticity of sample, also can avoid raffinate Crystallization Plugging pipeline in the pipeline between impact damper and inlet valve.
This sampler is applicable to malleation, the liquid phase systems in chemical plant installations.The sample authenticity is strong, and accuracy is high, without raffinate, residual gas discharging.Prevent that effectively poisonous, hazardous medium is to operator's injury.Environmental pollution and the wasting of resources have been avoided simultaneously.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done are within all dropping on protection domain of the present utility model.
