Description
Technical field
The present invention relates to a kind of Chemical Kinetics test instrument, particularly a kind of hazardous chemical is met water outgassing rate determination test appearance.
Technical background
In the chemicals; Possibly react when some material contacts with water and discharge gas; Possibly form explosive compound after these gases and the air mixed, and very easily ignited, explode, the impact of generation involves flame and possibly work the mischief to operating personnel and surrounding environment.In addition, meet water venting chemicals, especially meet the chemicals that water is emitted inflammable gas, must treat with a certain discrimination, might in fire extinguishing procedure, cause bigger harm on the contrary otherwise not only can not in time stamp out a fire in the fire-fighting fire extinguishing field.
The early stage water venting test instrument of meeting mainly adopts human metering, balance weighing data processing method to carry out; The experiment instrument of utility model patent CN2490569Y report for example; Its defective is that human metering be prone to produce calculation deviation, and the balance weighing method receives some chemicals to meet water reaction institute gas flow that generates water few, that be not enough to produce enough pressure discharge respective quality to cause test error; Though the chance water in later stage venting test instrument adopts flowmeter to carry out the gas flow monitoring and measures; But the interpolation of water needs manual operation during test; Test operation is loaded down with trivial details relatively, in addition, meets water and discharges the unprocessed direct discharging of inflammable gas; And the inflammable gas that reaction vessel and gas piping dead volume cause the later stage to discharge can not emit from reaction bulb fully, and these factors all can increase the harm of test to operating personnel and surrounding environment.
Summary of the invention
The purpose of this invention is to provide a kind of can the completion automatically and add water and gas-discharge operation; And can accurately measure the release gas flow in real time and the hazardous chemical that release gas is handled is met a kind of hazardous chemical chance of water outgassing rate test instrument water outgassing rate determination test appearance, it can overcome the above-mentioned deficiency that has dangerous material chance water venting test instrument at present now.
To achieve these goals, the technical scheme that the present invention taked is:
A kind of hazardous chemical is met water outgassing rate determination test appearance; It is characterized in that: nitrogen steel cylinder (1) through pipeline connect successively, first reduction valve (2), solenoid valve (3), pressure transducer (4), pipe end feeds in a bite of three mouthfuls of flat bottom flasks of reaction bulb (7); Connect infusion pump (6) through pipeline in another mouthful of three mouthfuls of flat bottom flasks of reaction bulb (7), infusion pump (6) connects reservoir (5); Three mouthfuls of flat bottom flasks of reaction bulb (7) connect solenoid valve (8) through pipeline in a bite again; Second solenoid valve (8) connects gas cleaning unit (9); Gas cleaning unit (9) connects gas meter (10), and gas meter (10) connects catalytic combustion method gas sensor (11); Computer control terminal (12) connects pressure transducer (4), infusion pump (6), gas meter (10).
Control terminal (12) connects printer (13).
Characteristics of the present invention are to come accurately control to add the speed and the amount of water through the infusion pump that connects control terminal, have saved manually operated loaded down with trivial details; Nitrogen through reaction bulb not only can prevent to react the refluence that discharges gas; And can take away fully because of reaction bulb and pipeline dead volume and cause remaining in the inflammable gas in the test instrument; Directly do not drain into atmosphere from the gas meter effluent air; But wherein inflammable gas is carried out fast detecting through catalytic combustion method gas sensor, avoid itself discharging of the harm of dangerous gas to operating personnel and surrounding environment because of testing; Being connected of control terminal and gas meter and pressure transducer can accurately be controlled nitrogen flow rate and monitor instantaneous velocity and the total flow that shows release gas in real time.
