Embodiment 1

[0037] This embodiment provides a closed-circuit circulation type volatile liquid explosion limit determination device, the structure of which can be found in figure 1As shown, it includes a closed circulation pipeline, and a liquid container 7, a weight sensor 8, an ignition mechanism, a turbine blade 5 and an electric heating element 11 arranged in the circulation pipeline, the liquid container 7 is fixedly placed on the weight sensor 8, and the turbine blade 5 is used to form the air flow circulating along the circulation pipeline, the electric heating element 11 is used to heat the air flow in the circulation pipeline, and the ignition mechanism is controlled by the outside and ignites at set intervals. When working, the turbine blades 5 start to form a circulating air flow. If necessary, the electric heating element 11 can be turned on to heat the air flow. With the flow of the air flow, the liquid sample placed in the liquid container 7 gradually evaporates, making the ai...

Abstract

The invention relates to a closed circulation type volatile liquid explosion limit measuring device which comprises a closed circulation pipeline, and a liquid container, a weight sensor, an ignitionmechanism and turbine blades which are arranged in the circulation pipeline; the liquid container is fixedly arranged on the weight sensor; the turbine blades are used for forming air flow circularlyflowing along the circulation pipeline, and the ignition mechanism is controlled by the outside and ignites at set intervals. Compared with the prior art, the device can solve the problems that an existing device is difficult to obtain the concentration of the mixed gas in time, the testing process is tedious, and various volatile liquids cannot be tested.

Description

technical field [0001] The invention belongs to the technical field of liquid explosion limit measuring devices, and relates to a closed-circuit circulation type volatile liquid explosion limit measuring device. Background technique [0002] At present, the hazard test item for volatile liquids in the transportation field is only the flash point test, and the result obtained is the temperature at which the volatile liquid forms a mixture with the outside air, flashes and burns immediately when it comes into contact with a flame. For the stability of the liquid after heating, the flash point temperature index can be given, but the vapor concentration index where the explosion occurs cannot be given, and the explosion limit of the mixed vapor of various volatile liquids cannot be investigated. [0003] Patents CN 105136854B and CN 105092642B disclose a liquid mixture explosion limit test device and the use method of the device, which are composed of an explosion chamber, a con...
