Tester of oxidizing liquid of dangerous article

Abstract

The invention discloses a tester of oxidizing liquid of a dangerous article. A pressure container main body is a thick-wall pressure tube; the upper end of the pressure tube is connected with a hollow explosion-proof disc holder; the side wall of the pressure tube is screwed with a piezometer tube of a pressure sensor; and the bottom of the pressure tube is connected with an igniter plug main body. The pressure container main body is arranged on a bracket slantwise and an organic glass shield is arranged outside the pressure container main body. An ignition system adopts the specific igniter plug and is heated by a nickel / chrome wire; the igniter can contact oxidizing chemicals and keeps good tightness at a high pressure; the pressure sensor detects the change condition of the air pressure in the pressure container; software processes data to obtain an average time of pressure rise and prints a test result, so the aim of analyzing and judging substances to be tested scientifically and efficiently is fulfilled. The whole tester is arranged in the organic glass shield with exhaust holes, so the accident which is caused by the rupture of the explosion-proof disc or the rapid pressure rise in the test process is avoided and the safety is relatively high.

Description

technical field [0001] The invention belongs to a dangerous goods tester, in particular to a dangerous goods oxidizing liquid tester capable of completing liquid dangerous goods including chemicals. Background technique [0002] Dangerous goods are international compulsory inspection commodities. If they are not handled properly during production, packaging, storage and transportation, accidents such as combustion, explosion, corrosion, and poisoning are likely to occur, causing harm to the environment and human health. Oxidizing liquids have the potential to significantly increase the burning speed or burning intensity of combustible substances when mixed with combustible substances, or the potential to form spontaneously ignitable mixtures when mixed with combustible substances. Whether chemical substances are oxidizing is an important indicator that needs to be determined in production, transportation and storage. Relevant test methods have been formulated at home and abr...
