Apparatus for testing velocity of inflammable gas given out by substance when contacting with water

Abstract

A device for testing the rate of inflammable gas given off when matter meets water is characterized in that a constant voltage separating funnel with a side pipe is communicated with a conical beaker by a three way pipe; the conical beaker is arranged in a thermostatic water bath circulator which is internally provided with water bath for heating and cooling; the side pipe of the constant voltage separating funnel and the outlet of the bottom thereof are respectively provided with a switch; the outlet at the side of the three way pipe is communicated with the air inlet of a flow meter; the air outlet of the flow meter is communicated with a surge flask; the input end of a monitor is connected with the output end of the flow meter. The device can be used for judging fatalness when the matter meets wet, has the real time supervisor control function, does not need manual time-keeping, weighting and calculation; after the testing is over, the starting time of the testing is input, and then the real time monitoring data can be led out, thus avoiding the problem that the manual weighting can not exactly measure the rate of inflammable gas given off when the matter meets water, meanwhile, saving the precious manpower and time and greatly improving work efficiency.

Description

technical field [0001] The invention relates to a device for testing the rate at which a substance emits flammable gas when meeting water. Background technique [0002] At present, dangerous goods are commodities under compulsory international import and export inspection. Due to the dangers of dangerous goods themselves, improper packaging during transportation can easily cause accidents such as combustion and explosion. In order to ensure the safety of dangerous goods during transportation, the dangerous goods must be correctly classified according to the international dangerous goods regulations before packaging, and the appropriate packaging category should be selected according to their hazard classification. In the past, safety accidents often occurred due to incorrect classification of dangerous goods, resulting in wrong selection of packaging categories. [0003] At present, there is no experimental device in which the substance emits flammable gas when it meets wat...

In the past, safety accidents often occurred due to incorrect classification of dangerous goods, resulting in wrong selection of packaging categories

[0003] At present, there is no experimental device in which the substance emits flammable gas when it meets water in the dangerous substance test instrument. The two methods of manual measurement and automatic processing of balance weighing data are generally used in China.

Using manual measurement, it is difficult to accurately measure the rate of gas generation at a certain moment, and it is prone to calculation deviations in release rate and release amount; while using the method of automatic processing of balance weighing data, although the accuracy of weighing time can be guaranteed, and There is no need for manual timing, weighing, calculation and judgment steps, but because the rate and flow of flammable gas produced by the substance in contact with water are very small, the released pressure cannot press the water in the gas collecting bottle into the balance of the weighing device. Therefore, the automatic processing method of balance weighing data cannot accurately test the rate at which the substance emits flammable gas when it meets water
