Calcination container and method

Abstract

The invention discloses a calcination container and method, and relates to the technical field of calcination. The calcination container comprises a flange, at least two air inlet passages and a vessel body, wherein the flange is provided with at least two air inlets; the air inlet passages and the air inlets are connected in one-to-one correspondence for introducing gas; the container body is used for performing calcination and comprises a large quartz tube and at least two small quartz tubes, wherein the small quartz tubes are located in the large quartz tube, and the small quartz tubes arein one-to-one correspondence with the air inlets. The calcination container has the advantages that two samples can be separately placed in the small quartz glass tubes, so that the samples cannot bemixed with each other during experiments and operation; different atmospheres are introduced through the two air inlets of the flange respectively to meet different reaction conditions required for the experiments; the flow rate of the gas in different air inlets can be controlled respectively, and the ratio of the amount of two substances can be adjusted by adjusting the flow rate; the placementpositions of the samples and the temperature zone position of the reaction between the two samples can be controlled by designing the length of different small quartz tubes.

Description

technical field [0001] The invention relates to the technical field of calcination, in particular to a calcination container and a calcination method. Background technique [0002] The quartz glass tubes and flanges used for ordinary calcining in the prior art usually have a single gas inlet. The single glass tube channel can meet most of the calcination reactions, but there are still some disadvantages in the process of use, such as two-phase co-volatility reactions: [0003] 1. Easy to mix: When two different samples are calcined together, since there is only one channel, it is easy to mix the samples due to the air flow during operation and experiment, and they cannot be reacted separately and then mixed. [0004] 2. It is difficult to react separately: the two samples may have different reaction atmospheres during the reaction, but only one gas can be fed into the single channel, and the reaction can only be carried out under the same atmosphere. [0005] 3. It is diff...

Problems solved by technology

[0003] 1. Easy to mix: When two different samples are calcined together, since there is only one channel, it is easy to mix the samples due to the airflow during operation and experiment, and they cannot be reacted separately and then mixed for reaction

[0004] 2. It is difficult to react separately: the two samples may have different reaction atmospheres during the reaction, but only one gas can be introduced into the single channel, and the reaction can only be carried out under the same atmosphere

[0005] 3. It is difficult to control the amount during the reaction process: the traditional device has only one air inlet pipe and only one sample placement place. When the two substances are calcined together, it is impossible to accurately control the air flow to control the amount of reaction

[0006] 4. When the self-volatility and reaction of the two substances are applicable to different temperature zones, it is impossible to control the reaction zone while controlling the temperature zone
