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:
The present invention relates to the heating-value determination instrument of coal in coal, petrochemical complex or the power industry, oil or other pyrogen, be specifically related to improvement existing calorimeter.
Background technology:
In the prior art field, the basic structure of the instrument of mensuration material thermal value has outer bucket, interior bucket and the oxygen bomb of specimen is housed, and wherein interior barrel places outer bucket, oxygen bomb is positioned in the interior bucket, be connected with spark electrode,, allow sample fully burn to official hour energising igniting.For guaranteeing to measure exactly the thermal value of material, outer bucket and interior bucket must be consistent with the temperature of oxygen bomb.Take out the about needs of this process about 18 minutes from the sample all burnt that is placed into of oxygen bomb, oxygen bomb is placed anteposition in environment temperature, in bucket in manually after the tester outside installs sample, placing again, thereby cause oxygen bomb self-temperature and the interior temperature of interior bucket inconsistent, barrel temperature changes in can making during storing, this just needs the regular hour to adjust, especially in weather comparatively cold season, at least need more than 5 minutes from putting into of oxygen bomb is consistent with interior barrel temperature, therefore, the time of a sample of every test does not meet the requirement of present modern production fast development with regard to corresponding prolongation yet.
Summary of the invention:
Technical matters to be solved by this invention is how further to shorten the equilibration time of temperature in each test oxygen bomb and the interior bucket, to improve test speed.
Realize by following technical scheme on the technical matters of the present invention.It comprises outer bucket, interior bucket and test oxygen bomb, it is characterized in that this instrument also is provided with the oxygen bomb to be tested that is in same environment temperature with interior bucket build-in test oxygen bomb.This oxygen bomb to be tested places in the interior bucket of constant temperature, and bucket places in outer barrel and with it and is communicated with in this constant temperature, or is communicated with outer barrel by being communicated with water pipe.Outside the bucket, also temperature-constant bucket can be set outside, oxygen bomb to be tested places in the constant temperature in the bucket, and bucket places in the temperature-constant bucket and with it and is communicated with in this constant temperature, or is communicated with temperature-constant bucket by being communicated with water pipe.
The present invention compared with prior art, can further guarantee that from structure oxygen bomb ambient temperature before test of each test is in a steady state value, and environment temperature is consistent during with test, be further perfect to the application's technology formerly, thereby reduced the test duration of each sample, improved test job efficient.
Description of drawings:
Fig. 1 is structure embodiment one of the present invention;
Fig. 2 is structure embodiment two of the present invention.
Among the figure:
1-tests oxygen bomb; Bucket in the 2-; The outer bucket of 3-; Bucket in the 4-constant temperature;
The 5-temperature-constant bucket; 6-freezes, heats machine; The 7-water circulating pump; 8-is communicated with water pipe;
9-oxygen bomb to be tested.
Embodiment:
Fig. 1 and Fig. 2 have showed two embodiment that the present invention uses respectively.
The present invention includes oxygen bomb 1, interior bucket 2 and outer bucket 3, follow-on calorimeter also is provided with temperature-constant bucket 5, and oxygen bomb 1 is loaded in the interior bucket 2, and interior bucket 2 is loaded in the outer bucket 3, and bucket 3 places in the temperature-constant bucket 5 outward, and whole device forms an airtight space.Refrigeration all is housed in bucket 3 and the temperature-constant bucket 5 outside interior bucket 2 or heats medium, each barrel is interconnected, be equipped with water circulating pump 7 in it, refrigeration, heat machine 6 and place in the temperature-constant bucket 5, can freeze by the temperature of setting according to the needs of test environment temperature or heat, constant oxygen bomb 1 environment temperature is constant when promptly testing on the artificial value of setting for bucket 2 residing environment temperatures in making, to guarantee the accuracy of test.The present invention is for shortening the test duration of each sample, also be provided with one and be positioned over the oxygen bomb to be tested 9 in the bucket 4 in the constant temperature, make its bucket 2 preceding its environment temperatures in being positioned over consistent with interior barrel 2, can shorten the setup time before this oxygen bomb is tested greatly, bucket 2 interior temperature are on the constant value all the time in can guaranteeing simultaneously.
As shown in Figure 1, bucket 4 places in the temperature-constant bucket 5 in the constant temperature of the present invention, and the calorimeter before improving can directly be located in the outer bucket 3, offers through hole on its barrel madial wall, is communicated with temperature-constant bucket 5 or outer bucket 3, can guarantee that oxygen bomb 9 environment temperatures to be tested are consistent with interior bucket 2 temperature.
As shown in Figure 2, bucket 4 places outside temperature-constant bucket 5 or the outer bucket 3 in the constant temperature of the present invention, connecting water pipe 8 by one joins, bucket 4 is provided with water circulating pump 7 in the constant temperature, by this water pump be connected water pipe 8 bucket 4 be communicated with temperature-constant bucket 5 or outer bucket 3, can guarantee that equally oxygen bomb 9 environment temperatures to be tested and interior barrel of 2 temperature are consistent.
During test, to test oxygen bomb 1 is positioned in the interior bucket 2, simultaneously next specimen can be put in the oxygen bomb 9 to be tested, after sample test in the interior bucket 2 finishes, owing to the sample combustion time is longer than bucket 4 intensification or temperature fall times in the constant temperature, desired steady state value when oxygen bomb 2 ambient temperatures to be tested have reached test already, when being placed in it in interior bucket 2, can light a fire immediately, thereby realize uninterruptedly carrying out of oxygen bomb test, improve test speed.
