Abstract
The utility model discloses a corrosion prevention device for gas concentration detector pipelines, which comprises a sampler and an analyzer. The sampler is inserted in a process pipeline, one end of the sampler is connected with a through terminal connector, which is disposed on a gas and liquid header, by a detector pipeline, a through terminal connector disposed at the bottom of the gas and liquid header is connected with an externally threaded stop valve by a seamless steel pipe and a gas choking drainage valve, and a through terminal connector arranged on the upper portion of the gas and liquid header is connected with the analyzer by a detector pipeline. The corrosion prevention device has the advantages that the corrosion prevention device is simple in structure and smart in design, is safe and reliable, and can effectively protect the detector pipelines so as to guarantee smooth sampling, the analyzer is prevented from being polluted by liquid, and the like.
Description
Technical field
The utility model relates to a kind of anti-corrosive apparatus, and particularly a kind of gas concentration detects the pipeline anti-corrosive apparatus.
Background technology
At present, in the coal gas system production run coal gas O2 concentration is monitored and must be carried out, coal gas dust removal mostly adopts high-voltage electrostatic dust separator; Be prone to blast or burn when O2 concentration surpasses certain numerical value in the dusty gas in the electric precipitator; Cause a serious accident, jeopardize equipment and personal safety, if in the process of sampling and conveying; The weather temperature is low or the sampling line heat insulation effect is bad; Appearance temperature degree is under its dewpoint temperature the time, and meeting such as institute's water content separated out and caused the gas-liquid two-phase stream in this all gas, again owing to contain H in kind gas
2Corrosive gass such as S, O
2+ H
2S+ H
2The liquid object of generations such as O can remain in corrodes pipeline perhaps with in the appearance gas entering analysis cabinet, to burn into pollution analyzers such as solenoid valve, floride-free compression mechanism coolers, so prior art and imperfection in the sampling line.
Summary of the invention
The purpose of the utility model is: provide a kind of simple in structure, practical, safe and reliable, can effectively protect detect pipeline sampling unobstructed, overcome analyser and detected the pipeline anti-corrosive apparatus, to overcome the deficiency of prior art by a kind of gas concentration of liquid contamination.
The utility model is to be constructed as follows: a kind of gas concentration detects the pipeline anti-corrosive apparatus; Comprise the ducted sampling thief of insertion process, analyser; One end of sampling thief is connected through detecting the directintermination joint that is provided with on pipeline and the gas-liquid collection case; The directintermination joint that is provided with in gas-liquid collection case bottom is connected with the external thread stop valve with the choke draining valve through weldless steel tube, is connected with analyser through the detection pipeline at the directintermination joint of gas-liquid collection upper box part setting.
Owing to adopted technique scheme; Sampling thief is after the ducted stopple coupon of insertion process is extracted appearance gas out; Appearance gas gets into gas-liquid collection case through detecting pipeline, and when appearance temperature degree was under its dewpoint temperature, the liquid that quilt such as institute's water content separated out the back generation in the appearance gas was assembled and is left in the gas-liquid collection case; The choke draining valve is discharged then, and moisture free gas gets into analyser and detects; Compared with prior art, the advantage that the utility model not only has is simple in structure, design is ingenious, safe and reliable, and can effectively protect detect pipeline sampling unobstructed, overcome analyser by advantages such as liquid contaminations.
Description of drawings
Fig. 1 is the utility model structural representation;
Description of reference numerals: the 1-sampling thief, 2-detects pipeline, 3-gas-liquid collection case, 4-directintermination joint, 5-weldless steel tube, 6-choke draining valve, 7-external thread stop valve, 8-analyser.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
The enforcement of the utility model: a kind of gas concentration detects the pipeline anti-corrosive apparatus; Shown in Fig. 1～3; Comprise the ducted sampling thief of insertion process 1, analyser 8; One end of sampling thief 1 is connected through the directintermination joint 4 that detects setting on pipeline 2 and the gas-liquid collection case 3; The directintermination joint 4 that is provided with in gas-liquid collection case 3 bottoms is connected with external thread stop valve 7 with choke draining valve 6 through weldless steel tube 5, and the directintermination joint 4 that is provided with on gas-liquid collection case 3 tops is connected with analyser 8 through detecting pipeline 2.
Directintermination joint 4, choke draining valve 6 and external thread stop valve 7 all are existing products on the market.
During the utility model work; Sampling thief 1 is after the ducted stopple coupon of insertion process is extracted appearance gas out; Appearance gas gets into gas-liquid collection casees 3 through detecting pipeline 2 through directintermination joint 4, and when appearance temperature degree was under its dewpoint temperature, the liquid that quilt such as institute's water content separated out the back generation in the appearance gas was assembled the bottom that is left to gas-liquid collection case 3; Outside choke draining valve 6 and external thread stop valve 7 vent pipes, moisture free kind of gas just gets into analyser 8 and detects then.
The utility model can effectively protect detect pipeline 2 samplings unobstructed, overcome analyser 8 by liquid contamination, guarantee to be worthy to be popularized the being quick on the draw property of analyser.
