Abstract
The utility model relates to a low pressure acid gas closed sampler, belonging to chemical gas sampling device, comprising a delivery pipe of acid gas and nitrogen evacuators. The nitrogen evacuators are arranged in parallel on the delivery pipe by the pipes and the sampling valves are installed between the nitrogen evacuator and the delivery pipe communicated with the nitrogen evacuator. The utility model has features of simple operation, instant sampling, no harm to the personal safety and no environment pollution.
Description
Technical field
The utility model belongs to chemical gases sampler field, specifically is the airtight sampling thief of a kind of low pressure sour gas.
Background technology
In the sulfur recovery facility of petrochemical complex at home and abroad and Coal Chemical Industry industry, sour gas needs frequent sampling analysis to form as the raw material of device, and produces according to forming to regulate.Sour gas operating temperature～40 ℃, on-stream pressure～0.05MPa (g), H
2S content is 30～95% (v), have low-pressure, highly toxic characteristics, usually sample mode is directly to extract from delivery line by sample valve at present, this sample mode needs the sour gas of emitting is constantly discharged for collecting fresh sample, operates very dangerous, sampling back pipeline inner acidic gas drains into the atmospheric pollution environment, alkali lye needs often to change, and produces alkaline residue and needs special processing, increases production cost to enterprise.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and prior art is improved, and provides a kind of simple to operate, can accurately take a sample immediately, and not endanger personal safety, the airtight sampling thief of low pressure sour gas free from environmental pollution.
For achieving the above object, the utility model is achieved through the following technical solutions:
It is the airtight sampling thief of a kind of low pressure sour gas, the delivery line and the nitrogen evacuation that comprise sour gas, the present technique main points are to be arranged in parallel the nitrogen evacuation by pipeline on the delivery line, simultaneously between nitrogen evacuation and the delivery line that links with it sampling valve are set.
For the ease of control nitrogen evacuation, can operation valve be set at the endpiece of nitrogen evacuation.
In addition, in order to overhaul conveniently, also can between sampling valve and delivery line, Safety control valve be set.
Owing in the petrochemical complex at home and abroad and the sulfur recovery facility of Coal Chemical Industry industry nitrogen is arranged all; the utility model is that power makes low pressure sour gas sealing and circulating in the sampling pipeline with nitrogen; design according to principle of hydrodynamics; utilization is installed in the pressure reduction that evacuation produced in the pipe conveying fluid; order about the circulation of fluid in the bypass; the sampling valve of installing in the circulation bypass; utterly destroyed the preceding flow dead of general sampling valve; thereby make and need not to discharge stagnant fluid; be convenient to the operation can adopt at any time fresh sample; reach and do not endanger personal safety when gathering fresh sample, the purpose of protection environment.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model embodiment 1 structural representation.
Embodiment
As shown in Figure 1, the airtight sampling thief of this low pressure sour gas, the delivery line 3,5 and the nitrogen evacuation 1 that comprise sour gas, the present technique main points are to be arranged in parallel nitrogen evacuation 1 by pipeline 4 on the delivery line 3,5, simultaneously between nitrogen evacuation 1 and the delivery line 3 that links with it sampling valve 2 are set.
For the ease of control nitrogen evacuation 1, can operation valve be set at the endpiece of nitrogen evacuation.
In addition, in order to overhaul conveniently, also can between sampling valve and delivery line, Safety control valve be set.
Owing in the petrochemical complex at home and abroad and the sulfur recovery facility of Coal Chemical Industry industry nitrogen is arranged all; the utility model is that power makes low pressure sour gas sealing and circulating in the sampling pipeline with nitrogen; design according to principle of hydrodynamics; utilization is installed in the pressure reduction that evacuation produced in the pipe conveying fluid; order about the circulation of fluid in the bypass; the sampling valve of installing in the circulation bypass; utterly destroyed the preceding flow dead of general sampling valve; thereby make need not to discharge stagnant fluid be convenient to work can adopt at any time fresh sample; gather fresh sample and do not endanger personal safety and reach; the purpose of protection environment, and simple to operate; safety, sample collecting is accurate.
Be further enhanced leaktightness, this whole sampling system can be placed in the airtight sampling box that sampling box is provided with the external tapping that needs, sampling box is placed on on-the-spot correct position, and connecing required pipeline can come into operation.
Claims (3)
1, the airtight sampling thief of a kind of low pressure sour gas, the delivery line and the nitrogen evacuation that comprise sour gas, it is characterized in that being arranged in parallel the nitrogen evacuation by pipeline on the delivery line, simultaneously between nitrogen evacuation and the delivery line that links with it, sampling valve is set.
2, the airtight sampling thief of low pressure sour gas according to claim 1 is characterized in that the endpiece of nitrogen evacuation is provided with operation valve.
