Problems solved by technology

Due to the different nature of endothermic and exothermic, and the degree of intensity is uncertain each time, the process is long. In this process, even if the temperature reading of the outer barrel is the same, the heat capacity of the instrument may vary greatly, resulting in a decrease in the accuracy of the test results and poor reproducibility. become worse

Embodiment 1

[0054] Embodiment 1: as figure 1 and image 3 As shown, the outer barrel partition 5 is radially arranged in the outer barrel cavity 23 along the center line of the outer barrel 2, along the flow direction of the medium, between the first sub-cavity 201 and the last sub-cavity 201 A third intermediate partition 204 is provided, which completely separates the medium inlet part and the medium outlet part. Wherein, part of the outer tub partition 5 is connected with the top of the outer tub cavity 23, and another part of the outer tub partition 5 is connected with the bottom of the outer tub cavity 23, so the outer tub partition 5 is connected with the outer tub cavity 23 There is a gap between the inner wall of the top end or the inner wall of the bottom end to allow the medium to pass through, so that the various sub-cavities 201 are connected to each other in turn, and the medium can flow from the first sub-cavity 201 through each sub-cavity 201 to the last sub-cavity. Cavit...

Embodiment 2

[0055] Embodiment 2: as Figure 4 and Figure 6 As shown, in this embodiment, the outer barrel partition 5 is radially arranged in the outer barrel cavity 23 along the centerline of the outer barrel 2, and along the flow direction of the medium, the first secondary cavity 201 and the last secondary cavity 201 A third intermediate partition 204 is provided therebetween, and the third intermediate partition 204 completely separates the medium inlet part and the medium outlet part. Wherein, there is a gap that allows the medium to pass between part of the outer tub partition 5 and the outer wall of the outer tub cavity 23, and a gap that allows the medium to pass is maintained between part of the outer tub partition 5 and the adjacent outer tub partition 5. , so that each sub-cavity 201 communicates with each other in turn, the medium can flow from the first sub-cavity 201 through each sub-cavity 201 to the last sub-cavity 201, during the flow process, due to each sub-cavity 201...

Embodiment 3

[0056] Embodiment 3: as Figure 7 and Figure 9 As shown, in this embodiment, the outer tub partitions 5 are arranged in parallel in the outer tub cavity 23, wherein some of the outer tub partitions 5 are connected to the top of the outer tub cavity 23, and some of the outer tub partitions 5 are connected to the outer tub cavity 23. The bottom of the barrel cavity 23 is connected, so there is a gap between the outer barrel partition 5 and the top inner wall or the bottom inner wall of the outer barrel cavity 23 to allow the medium to pass through, so that the secondary cavities 201 are connected to each other in sequence, The medium can flow from the first sub-cavity 201 through each sub-cavity 201 to the last sub-cavity 201. During the flow process, since the communication positions of each sub-cavity 201 are inconsistent, the medium passes through each sub-cavity The speed and direction of movement of the body 201 are different, and the volume passed through will also be di...

Abstract

This invention discloses a calorimeter with its outer drum with a close circuit cavity circulation temperature control device including an inner drum, an outer drum and a cover set on the top of the two drums, in which, the inner drum is set in the outer one, an outer drum cavity with medium is set between the inside and outside walls of the outer drum, an air interlayer is set between the inner and outer drums, one or more than one clapboards are set in the cavity of the outer drum to separate the inner cavity into two or more than two sub-cavities to constitute a closed circuit cavity circulation temperature control device with the circulation supply device including a temperature control device and a drive device.

Description

technical field [0001] The invention mainly relates to a measuring instrument for measuring the calorific value of coal, oil or other exothermic substances in coal, petrochemical or electric power industries, in particular to a calorimeter with a closed-circuit cavity circulation temperature control device in an outer barrel. Background technique [0002] In the prior art, the measuring instruments used to determine the calorific value of substances are generally composed of an inner barrel, an outer barrel and a barrel cover arranged on the top of the inner barrel, wherein the inner barrel is arranged in the outer barrel; when testing, the oxygen bomb of the test sample is placed on the In the inner barrel, it is connected with the ignition electrode, and the ignition is energized at the specified time, so that the sample can be fully burned. In order to ensure accurate determination of the calorific value of the substance, the temperature of the outer barrel and the inner ...
