Abstract
The utility model provides a high pressure micro water and sulfur detection system dedicated to compressed natural gas. The system comprises a micro water detection part and a hydrogen sulfide detection part, wherein the micro water detection part consists of a high pressure needle valve and a micro water detector connected with an outlet of the high pressure needle valve; the hydrogen sulfide detection part is connected with the outlet of the micro water detector through a pipeline and a high pressure regulator; and meanwhile, the hydrogen sulfide detection part is connected with a sample gas outlet needle valve through a pipeline. The detection system has compact structure, simple installation, high detection accuracy, stable and reliable work, anti-explosion function and high cost performance, can detect the content and pressure of micro water and hydrogen sulfide in the compressed natural gas continuously and dynamically on line, and is mainly used for detecting natural gas products.
Description
Technical field
The utility model relates to a kind of gas detecting system, particularly relates to a kind of compressed natural gas special high-pressure Wei Shui, little sulphur detection system.
Background technology
Existing rock gas moisture detector, a kind of gas phase high pressure dew point hygrometer is disclosed as Chinese patent 2008200619365, under high pressure detected pressures and dew point, but owing to sample gas is not carried out pre-service, greasy dirt in the rock gas is bigger to the pollution of sensor, thereby influenced the serviceable life of instrument, and this instrument has only simple function, can only detect the micro-moisture content in the rock gas.And existing hydrogen sulfide gas detector is low pressure H independently, also only has simple function, and can only work under the low pressure condition of＜0.3Mpa, thus can only detect raw natural gas, can not the testing product rock gas.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, collects two kinds of functions and is one, and is simple in structure, easy to use, stable and reliable for performance, is exclusively used in compressed natural gas special high-pressure Wei Shui, little sulphur detection system that the product rock gas detects.
This real new type of compression rock gas special high-pressure Wei Shui, little sulphur detection system comprise Wei Shui test section and sulfuretted hydrogen test section.The Wei Shui test section is made up of with little water gauge that the high-pressure needle valve outlet is connected high-pressure needle valve, and the sulfuretted hydrogen test section is connected with little water gauge outlet by pipeline and high-voltage regulator, is connected with sample gas outlet needle valve by pipeline simultaneously.Wherein, little water gauge comprises the makings pretreater that is connected with high-pressure needle valve, the blowdown needle valve that is connected with makings pretreater lower end, the sampler that is connected with makings pretreater upper end.The makings pretreater is arranged on the cavity in the housing by housing, is arranged on the garden tube filter core in the cavity, and the hollow filter shaft that is arranged in the tube filter core of garden is formed.The cavity lower end is connected with the blowdown needle valve; Sampler is by housing, is arranged on the gas channel in the housing, and pressure transducer that is connected with gas channel and dew point transducer are formed, and gas channel is connected with hollow filter shaft and enter the mouth with high-voltage regulator by pipeline and to be connected; The sulfuretted hydrogen test section comprises with the one end and being connected with the high-voltage regulator outlet by pipeline, the sulfuretted hydrogen sampler that the other end is connected with sample gas outlet needle valve by pipeline, and the hydrogen sulfide sensor that is connected with the sulfuretted hydrogen sampler.
The principle of work of this real new type of compression rock gas special high-pressure Wei Shui, little sulphur detection system is that tested test sample gas enters in the cavity of makings pretreater through high-pressure needle valve, behind the tube filter element filtering of garden, enter hollow filter shaft, enter the gas channel in the sampler again, dew point transducer and pressure transducer are passed to main frame with detection signal and handle and show that the dirt that garden tube filter core leaches is discharged by the blowdown needle valve; Sample gas in the gas channel enters the sulfuretted hydrogen sampler by pipeline simultaneously after the high-voltage regulator step-down, by hydrogen sulfide sensor detection signal is passed to main frame again and handles and show.Read high pressure Wei Shui, little sulfur content and pressure from main frame.
The advantage of this real new type of compression rock gas special high-pressure Wei Shui, little sulphur detection system is compact conformation, and the accuracy of detection height is installed simply, working stability is reliable, and has explosion prevention function, cost performance height, but little water, hydrogen sulfide content and pressure in the on-line continuous, detection of dynamic compressed natural gas.Be mainly used in the detection of product rock gas.
