Description
Technical field
The present invention relates to the improvement that there is the application apparatus of working environment in Simulated Water steam, specifically is a kind of saturated water vapor generator, and it belongs to the measuring instrument technical field of material heat endurance.
Background technology
Calorimetry instrument in accelerated speed of the prior art (abbreviates as: ARC) become one of means of testing commonly used of estimating the material heat endurance in the world, and progressively developed to being called the standard method of test direction.Yet this instrument only can be with closed system. be research object.And often be to be research object in industrial practical application with the open system.In order to expand the scope of application of ARC, make that the gas system of ARC is a research object with the open system, make it use the operating environment that more is intended for industrialized unit; This just needs to increase open gas system, joins in the ARC system.The steam generator of prior art generally is a boiler formula high temperature and high pressure steam system.Yet the working environment that Simulated Water steam exists in the ARC system does not need high temperature and high pressure steam.Technological difficulties to be solved by this invention are: satisfy the demand to the steady supply of the cryogenic gas of adjustable certain flow, also will satisfy simultaneously carrying the demand of saturated vapor secretly, also will satisfy the problem of effective solution vapor-liquid separation again.According to the situation of literature search and market survey, still there is not the experimental rig that similarly supplies the working environment that Simulated Water steam exists in the ARC system both at home and abroad.
Summary of the invention
The objective of the invention is to provide a kind of saturated water vapor generator for the open gas system of the working environment of Simulated Water steam existence in the ARC system.This generator is for satisfying ARC the demand of carrying the saturated vapor air secretly to be designed.The requirement of the steady supply of this designed generator also will satisfy ARC above-mentioned cryogenic gas to adjustable certain flow, thus satisfied the security evaluation of the operating environment in the simulation petrochemical equipment.
The objective of the invention is to realize that by following technical scheme developed a kind of saturated water vapor generator, it comprises: have electric heater, temperature controller, the water bath with thermostatic control airtight container of upper and lower water pipeline.Appropriate position in this container water layer upper cavity is provided with the vapor-liquid separation layer, the gas feed pipe end that passes this chamber wall immerses in the water layer bottom, gas outlet tube one end is arranged on the appropriate position in the vapor-liquid separation layer upper cavity, and the other end of this gas outlet tube passes in the example reaction chamber that this chamber wall is switched to system.
Described vapor-liquid separation layer, it is the glass fiber cotton layer, or be perlite matter layer, or is the asbestine layer: the thickness of this vapor-liquid separation layer is at 1-5mm.
Described water bath with thermostatic control airtight container, the temperature controlling range of its temperature controller customization is at 5-100 ℃.
Described gas, itself or be the air of certain flow, or be the nitrogen of certain flow; This gas flow scope is below the 200mL/min.
The invention has the advantages that: owing to developed a kind of saturated water vapor generator, it comprises: have electric heater, temperature controller, the water bath with thermostatic control airtight container of upper and lower water pipeline.Appropriate position in this container water layer upper cavity is provided with the vapor-liquid separation layer, the gas feed pipe end that passes this chamber wall immerses in the water layer bottom, gas outlet tube one end is arranged on the appropriate position in the vapor-liquid separation layer upper cavity, and the other end of this gas outlet tube passes in the example reaction chamber that this chamber wall is switched to system.Because electrically heated rod in the water bath with thermostatic control airtight container and temperature controller can be controlled in temperature 5-100 ℃ of water bath with thermostatic control, to obtain the temperature of the desired water vapour of experiment.When bottom that the air (or nitrogen) of certain flow is continued to feed water bath with thermostatic control via stainless steel tube, sufficient the contact arranged with the water of specified temp, increase along with the internal pressure of water bath with thermostatic control, the air of carrying water vapour (containing fine drop) secretly via glass silk flosssilk wadding layer (or for perlite matter layer, or be the asbestine layer) time, thereby tiny drop is adsorbed the effect of having played vapor-liquid separation by vapor-liquid separation layers such as glass silk flosssilk waddings, and the air (or nitrogen) of then carrying water vapour secretly leaves water bath with thermostatic control via gas outlet tube.Expand the scope of application of ARC based on the saturated water vapor generator of ARC exploitation, can simulate potential runaway reaction and quantize heat, the pressure hazard of some chemicals and mixture, promptly be used to study the thermostability and the assessment of hot harmfulness of material.
