Calorimeter based on temperature control technology

Abstract

The invention discloses a calorimeter based on a temperature control technology. The calorimeter comprises an outer barrel (12) and an oxygen bomb inner barrel (9), wherein the outer barrel is communicated with the oxygen bomb inner barrel (9) by virtue of a guide tube (14) and a pump body (15); a temperature sensor (8) is arranged in the oxygen bomb inner barrel; an outer barrel temperature control sensor (4) is arranged in the outer barrel; a quicksilver standard thermometer, and heating equipment and refrigerating equipment for controlling the temperature of a heat-conducting medium are also arranged in the outer barrel; stirring equipment (2) is also arranged in the outer barrel; and the heating equipment, the refrigerating equipment and the stirring equipment are used for receiving a control signal of an outer barrel temperature controller to realize corresponding heating and refrigeration operations. According to the calorimeter, under the actions of heating and refrigeration, the temperature of water in the outer barrel can be controlled to be at 20 DEG C, the error is defined to be between -0.1 DEG C and 0.1 DEG C and is shown on a temperature-controlled meter, so that the calorimeter has the advantage of intuition property; and the error also can be displayed by utilizing the computer so that the accuracy is extremely high; and moreover, the calorimeter can be continuously used for a long time without being influenced by external environment. The calorimeter based on the temperature control technology has the characteristics of high calorimetric working efficiency, accurate measurement of calorific value and capability of continuously working.

Description

technical field [0001] The present invention relates to a calorimeter, and more specifically relates to the improvement of the working principle and structure of the calorimeter. Background technique [0002] Calorimeters are also called calorimeters, calorimeters or calorimeters. According to GB / T384 Determination of Calorific Value of Petroleum Products, the calorimeter is composed of a calorimetric vessel and the water, oxygen bomb, stirrer and thermometer in it. The calorimeter is mainly used to measure the calorific value of solid combustibles such as coal, coke, and gangue to measure the quality of the measured object. Widely used in electric power, coal, metallurgy, petrochemical, quality inspection, environmental protection and other industries. It is the main instrument of coal quality laboratory. [0003] The problem is that the calorimeters of coal and petroleum products in the prior art have large calorific errors, are greatly affected by the surrounding envir...

AI Technical Summary

Problems solved by technology

[0004] Specifically, during the calorimetric work process of the calorimeter, the water temperature rises, because the water temperature rises, the calorific value is inaccurate and the error is large

And the water temperature rises to a certain level, and it cannot continue to work, so it cannot meet the requirements of continuous work.

The method in the prior art only relies on the external environment to affect the water temperature of the outer barrel, and the outer barrel has no heating or cooling equipment. Only when the water temperature returns to the working temperature can it continue to work, and the work efficiency is low.

Moreover, due to the unstable temperature, the measured calorific value error is also large.
