Problems solved by technology

The process from placing the oxygen bomb to taking out the sample after burning takes about 18 minutes. Before the oxygen bomb is placed, it is at the ambient temperature. The temperature of the inner barrel is inconsistent with the temperature of the inner barrel, and the temperature of the inner barrel will change when it is placed, which requires a certain amount of time to adjust, especially in cold weather, it takes at least 5 minutes from the time the oxygen bomb is put in to the temperature of the inner barrel. Above, therefore, the time for each test sample will be extended accordingly, which does not meet the requirements of the rapid development of modern production

Embodiment Construction

[0012] figure 1 and figure 2 Two embodiments of the application of the present invention are shown respectively.

[0013] The present invention comprises an oxygen bomb 1, an inner barrel 2 and an outer barrel 3, and the improved calorimeter is also provided with a constant temperature barrel 5, the oxygen bomb 1 is installed in the inner barrel 2, and the inner barrel 2 is installed in the outer barrel 3, and the outer barrel 3 is placed in the constant temperature bucket 5 again, and the whole device forms an airtight space. Both the inner barrel 2, the outer barrel 3 and the constant temperature barrel 5 are equipped with cooling or heating medium, and each barrel is connected to each other, and a circulating water pump 7 is installed in it. The temperature needs to be refrigerated or heated according to the set temperature, so that the ambient temperature of the inner barrel 2 is kept constant at an artificially set value, that is, the ambient temperature of the oxygen ...

Abstract

The invention discloses a rapid determination calorimeter, which comprises an outer barrel, an inner barrel and a testing oxygen bomb, characterized by that the apparatus also install a testing oxygen bomb having the same ambient temperature with the testing oxygen bomb in the inner barrel, the testing oxygen bomb is positioned in the thermostatic inner barrel, which is positioned in and connected to the outer barrel, or connected to the outer barrel through a communication pipe, the testing oxygen bomb is positioned in the thermostatic inner barrel, which is positioned in and connected to the thermostatic barrel, or connected to the thermostatic barrel through a communication pipe. The invention can further guarantee that each oxygen bomb tested are at a constant value in the ambient temperature.

Description

Technical field: [0001] The invention relates to an instrument for measuring the calorific value of coal, oil or other exothermic substances in coal, petrochemical or electric power industries, in particular to the improvement of the existing calorimeter. Background technique: [0002] In the prior art, the basic structure of an instrument for measuring the calorific value of a substance includes an outer barrel, an inner barrel and an oxygen bomb equipped with a test sample, wherein the inner barrel is placed in the outer barrel, and the oxygen bomb is placed in the inner barrel, which is connected to the ignition electrode. Turn on the electricity and ignite at the specified time to allow the sample to fully burn. In order to ensure accurate determination of the calorific value of the substance, the temperature of the outer barrel and inner barrel must be consistent with that of the oxygen bomb. The process from placing the oxygen bomb to taking out the sample after burni...
