Description
Technical field
The utility model relates to gas-detecting device technical field, be in a kind of vinyl chloride conversion gaseous mixture acetylene gas with
Hydrogen chloride gas detection device.
Background technique
In course of production of chloroethylene, acetylene gas and HCl gas reaction are in Hgcl2As producing chlorine under conditions of catalyst
Ethylene, reaction principle is simple, technical maturity, but has a problem in that participate in reaction gas main component with C at present2H2With
Based on HCL, and participating in reaction gas main component in actual production has O2、CO、CO2、N2, dust, benzene, high waste etc. more than 40
Kind gas, complicated component, for wherein C2H2Just it is not easy to measure with the content of HCL, can not accomplishes that qualitative, quantitative standard is surveyed
It is fixed.C2H2Reacting with HCl is divided into foreground and backstage, and foreground conversion ratio is 70% or so, and backstage conversion ratio can reach 97% or so,
Foreground is met at general pipeline and is carried out backstage reaction by many converter parallel combinations；Foreground conversion ratio is set to reach 70% with regard to needs pair
Every reaction kettle carries out gas sampling inspection, measures wherein C2H2With HCl gas content, conventional method is that band is installed on pipeline
There is an air exhaust head of Rubber end, worker injects Rubber end with needle tubing, draw gas, the kettle inspection of needle tubing coordinate is given, used in inspection center
Method be chromatography, using U.S. 7980 chromatographs in day, using stainless stee l packed column, 50m capillary column, such method can accomplish
C2H2With the measurement of HCl content, but disadvantage is: (1) elapsed time is too long, and the result time is slow out, from sampling to inspection, then
It is come out to analysis result, needs to expend about four hours.Environment is caused since converter large number of conversion sample in foreground leaks
There is pollution, personnel are endangered greatly, every requires pumping body and makees sample, is then sent for detecting；Large labor intensity, detection time be long,
As a result feedback is slow, if C occurs2H2It is unbalance with HCl gas ratio, later production link generation is seriously affected, to foreground and
When adjust C2H2There is lagging influence with HCl temperature, pressure, more catalyst changeout etc.；(2) large labor intensity needs to be equipped with related special
Industry personnel are responsible for sample drawn gas, send to inspection center, inspection center need to be equipped with skilled addressee be responsible for detection dispensed
Gas, the repeatability that works is strong, and mechanical strength is big, need to be equipped with corresponding number of units chromatograph, considerably increase input cost；(3) due to
Conventional method is inserted by needle tubing, and Rubber end sample drawn gas is exposed to the sun because Rubber end is exposed outside through the sun, for a long time,
Rubber end aging, causes that seal for pipe joints is tight, gas overflowing.Summer always has one layer of light fog to shroud and inspects by random samples on foreground
Around device, gas is inflammable and explosive and toxic.(4) because acetylene gas and hydrogen chloride gas leak, because reaction kettle is with mercury chloride
It causes damages so containing mercury ingredient in mixed gas produced to the health of sampling Detection personnel for catalyst, people
Member needs to be discharged in atmosphere by the gas of extraction, then with needle tubing, is repeated several times, it is ensured that the gas sampled is newest production
Gas out checks body so every few years operator requires to hospital to check UP, beats a kind of body and arranges mercury
Needle, the injury to human body are very big.
