Embodiment 1

[0028] Such as figure 1 As shown, the fuel explosion performance measurement system of the present invention includes a computer, a main control system 1 and a high-pressure air supply device connected to the main control system 1, a sampling device, an explosion chamber 2, an ignition device 4 and a vacuum device 5; An information collection device 3 is fixed on the inner wall of the chamber 2; an ignition electrode is detachably installed on the top of the explosion chamber 2, and the upper part of the ignition electrode is connected with the ignition device 4; the explosion chamber 2 is connected with the sampling device and the vacuum device 5; the computer and The information collection device 3 is connected.

[0029] The above scheme has been able to complete the determination of fuel explosion performance, and the preferred scheme is given below on this basis:

[0030] Such as figure 1As shown, the fuel explosion performance measurement system also includes a constant...

Embodiment 2

[0035] A kind of method that adopts embodiment 1 fuel explosion performance measurement system to carry out the method for fuel explosion performance measurement, comprises the steps:

[0036] A. Clean the inner wall of the explosion chamber 2 and the ignition electrode; seal and fix the explosion chamber 2, insert the ignition electrode; open the thermostatic device 6, keep the temperature of the explosion chamber 2 and the liquid fuel supply device 10 at 60°C, and open the liquid fuel supply device 10. Inject 50ml of light diesel oil into the microcomputer-controlled variable particle size atomization system 11, and seal the cover; the main control system 1 inputs a constant pressure to the microcomputer-controlled variable particle size atomization system 11 through the high-pressure dry air pipeline 7 for gas sampling air, the constant pressure is greater than the internal pressure of the microcomputer-controlled variable particle size atomization system 11; run the liquid ...

Embodiment 3

[0040] In this embodiment, the main control system parameters are set as follows: the internal pressure of the microcomputer-controlled variable particle size atomization system 11 is 2.0 Mpa, the internal vacuum degree of the explosion chamber 2 is 0, the ignition delay time is 600 ms, the ignition duration is 1000 ms, the temperature and The start time of pressure collection is 0 ms, that is, the collection starts at the moment of injection, the collection duration is 3000 ms, and the collection time interval is 10 ms; other steps are the same as in Embodiment 2.

[0041] The measurement result of this embodiment is: the explosive performance of light diesel oil is better than that of n-dodecane.

Abstract

The invention discloses a fuel explosive performance testing system. The fuel explosive performance testing system comprises a computer, a main control system (1), and a high-pressure air supply device, a feeding device, an explosive cabin (2), an ignition device (4) and a vacuumizing device (5) which are connected with the main control system (1), wherein an information acquisition device (3) is fixedly arranged on the inner wall of the explosive cabin (2); an ignition electrode is detachably installed on the top of the explosive cabin (2), and the upper part of the ignition electrode is connected with the ignition device (4); the explosive cabin (2) is communicated with the feeding device and the vacuumizing device (5); the computer is connected with the information acquisition device (3). By adopting the fuel explosive performance testing system, the gases can be mixed in any ratio; various data indexes can be measured by the information acquisition device in real time so as to systematically represent the explosive performance of fuel.

Description

technical field [0001] The invention relates to an explosion performance measurement system and a measurement method, in particular to a fuel explosion performance measurement system and a fuel explosion performance measurement method. Background technique [0002] In real life, the explosion of fuel has caused huge personal injuries and economic losses to human beings. In the process of developing new safe fuels, how to evaluate the explosive performance of safe fuels has become the first problem to be solved. Relevant patents and reports that meet this requirement. Patent CN 01211807.9 "Testing Device for Explosiveness of High-Temperature Combustible Vapor" is used to measure the explosion limit of flammable vapor, ignition temperature and other parameters, but saturated vapor cannot simulate the aerosol state formed by oil spilling after the fuel tank bursts under real conditions. In "gas explosion limit and fire resistance demonstration test device" (CN89217624.5), "mix...
