A liquid flammability test device for on-site detection

Abstract

The invention relates to a liquid inflammability test device for on-site detection. The device comprises a sampling unit and a test unit used together with the sampling unit, wherein the test unit comprises a base, a burning furnace, a thermocouple, an electric heating wire, a temperature recorder and a heating power supply, wherein the burning furnace is arranged at the top of the base and is fixedly connected with the base, the thermocouple and the electric heating wire are arranged in the burning furnace, the temperature recorder is electrically connected with the thermocouple, and the heating power supply is electrically connected with the electric heating wire; and the sampling unit comprises an expansion link, a paper core blocking base and a paper core, wherein the expansion link is arranged in the burning furnace, the bottom end of the expansion link is inserted into the burning furnace, the paper core blocking base is fixed at the bottom end of the expansion link, and the paper core is filled in the paper core blocking base. Compared with the prior art, the liquid inflammability test device for on-site detection has the advantages of small volume, portability and onsite direct use; a fire-insulating structure is arranged in the burning furnace, and a 12V voltage battery can be used for heating a heating part, so that the safety is high; and the tail gas is treated, so that air pollution can be prevented.

Description

technical field [0001] The invention belongs to the technical field of chemical detection, and relates to a liquid flammability test device for on-site detection. Background technique [0002] The safety of liquids, especially flammable liquids, has attracted more and more attention during daily storage, transportation, and use. Therefore, the evaluation of the flammability of liquids is becoming more and more important. In general, the evaluation of the flammability of liquids is done in the laboratory by closed-cup flash point testing. Although this method is highly accurate, the flash point test needs to be done with a flash point tester, which is generally The cost is high, and it can only be used in the laboratory, and cannot be used in on-site testing, which has certain limitations. [0003] However, most of the flammable liquid detectors currently on the market that are suitable for on-site detection can only judge whether they are flammable or not, but it is not cer...

In general, the evaluation of the flammability of liquids is done in the laboratory by closed-cup flash point testing. Although this method is highly accurate, the flash point test needs to be done with a flash point tester, which is generally The cost is high, and it can only be used in the laboratory and cannot be used in on-site testing, which has certain limitations

[0003] However, most of the flammable liquid detectors currently on the market that are suitable for on-site detection can only judge whether they are flammable or not, but it is not sure which temperature point can make the liquid burn, basically only qualitative tests can not be done quantitatively In addition, the price of general flammable liquid detectors is quite high, so it is not very widely used for on-site quantitative testing
