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
The present invention relates to a kind of device of testing velocity of inflammable gas given out by substance when contacting with water.
Background technology
At present, dangerous material are international commodity of importing and exporting forced examination, because the danger that dangerous material are possessed self, if the improper generation that is easy to cause accidents such as burning, blast of its packing in transportation.In order to guarantee the safety of dangerous material in transportation, must before packing, carry out correct danger classification, the packing classification suitable to dangerous material according to its dangerous categorizing selection according to international dangerous cargo rule.In the past, often because Classification of Dangerous is incorrect, selection is packed classification and security incident is taken place with leading to errors.
Do not see as yet in dangerous material material experiment instrument that at present material meets the experimental provision that water is emitted inflammable gas, two kinds of methods are handled in domestic human metering that generally adopts and the robotization of balance weighing data.Adopt human metering, be difficult to measure accurately the speed of a certain moment generation gas, occur the calculation deviation of rate of release and burst size easily; And the method that adopts the robotization of balance weighing data to handle, though can guarantee weighing accuracy constantly, and do not need steps such as manual time-keeping, weighing, calculating and judgement, but because the inflammable gas speed and the flow of material chance water generates are all very little, the pressure that discharges can't be pressed into the water in the gas bottle in the beaker on the meausring apparatus balance at all, therefore, balance weighing data robotization facture accurately test substances meet the speed that water is emitted inflammable gas.
In view of the foregoing, urgent need can be met the speed that water is emitted inflammable gas by accurate test substances at present, meets wet dangerous foundation as judging.
Summary of the invention
The purpose of this invention is to provide a kind of accurately test substances and meet the device of water reaction velocity of inflammable gas given out, it can satisfy the demand of prior art.
A kind of device of testing velocity of inflammable gas given out by substance when contacting with water, it is characterized in that having the constant voltage separating funnel of a band side pipe, it is communicated with conical flask by three-way pipe, and the latter places the water bath with thermostatic control circulator, and heating and cooling water-bath are equipped with in water bath with thermostatic control circulator inside; Switch is equipped with at the side pipe of constant voltage separating funnel and outlet at bottom place respectively; The side exit of three-way pipe and the air intake opening of flowmeter are communicated with, and the gas outlet of flowmeter is communicated with surge flask; The input end of display is connected with the output terminal of flowmeter.
The application of the device of above-mentioned testing velocity of inflammable gas given out by substance when contacting with water in judging the wet danger of material chance.
The present invention judges that by the chance water reaction velocity of inflammable gas given out size that wet material is met in test the chance of material is wet dangerous, adopt accurate flow measurement test system that gas velocity and flow that material produces in meeting the water course of reaction are monitored in real time, avoided method of testings such as human metering and balance weighing data robotization processing can accurately metered dose not meet the problem of water velocity of inflammable gas given out, simultaneously also save valuable manpower and time, greatly improved work efficiency.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
As shown in the figure, the present invention has the constant voltage separating funnel 1 of a band side pipe, and it is communicated with conical flask 5 by three-way pipe 4, and the latter places water bath with thermostatic control circulator 6, and heating and cooling water-bath are equipped with in water bath with thermostatic control circulator 6 inside; Switch 2 and 3 are equipped with respectively in the side pipe of constant voltage separating funnel 1 and outlet at bottom place; The air intake opening of the side exit of three-way pipe 4 and flowmeter 8 is communicated with, and the gas outlet of flowmeter 8 is communicated with surge flask 9; The input end of display 7 is connected with the output terminal of flowmeter 8.The 6 employing water-baths of water bath with thermostatic control circulator are heated or are freezed; Open switch 2 and switch 3 when joining water in the sample simultaneously, guarantee that the pressure in the conical flask 5 is consistent before adding water He after adding water; The air intake opening of three-way pipe 4 and flowmeter 8 is communicated with hose, and the gas outlet of flowmeter 8 is communicated with the surge flask 9 usefulness hoses of gas release portion, and the gas of generation is discharged by gas outlet 10.
When using device of the present invention, at first the water bath shampoo body medium is joined in the water bath with thermostatic control circulator 6, the attaching plug of water bath with thermostatic control circulator 6, display 7 and accurate flowmeter 8 is connected with power supply, open the switch of water bath with thermostatic control circulator 6, preheating or precooling; The testing sample that weighing 25g anticipates, insert in the 250mL conical flask 5, the conical flask 5 that testing sample is housed is put into water bath with thermostatic control circulator 6, close the switch 2 and the switch 3 of constant voltage separating funnel 1,200mL water is joined in the constant voltage separating funnel 1, and guarantee that the sample test part is immersed in below the water-bath liquid level fully; Start accurate flowmeter 8, on the desktop of display 7, open chance water and emit the inflammable gas test procedure, the sample test numbering and the test start time of testing sample are set, click operation, open the switch 2 and the switch 3 of constant voltage separating funnel 1 simultaneously, water is joined in the conical flask 5, after treating that water all enters into conical flask 5, off switch 2 and switch 3, system begins test, end of test (EOT) after 7 hours, input off-test time, and log-on data derivation program are after data to be tested derive fully, record test data is preserved; After the end of test (EOT), the taking-up testing sample is also dealt carefully with, and withdraws from and meets water reaction test system, closes the power supply of accurate flowmeter 8, display 7 and water bath with thermostatic control circulator 6.
