Description

TECHNICAL FIELD

[0001] The utility model belongs to catalytic equipment technical field, concretely relates to a high temperature even reaction device. BACKGROUND

[0002] High temperature even reaction is the core process link of realizing material synthesis, catalyst preparation and energy conversion in chemical industry, metallurgy and new energy field. In prior art, this kind of reaction usually adopts static heating scheme: after the reaction kettle is sealed, it is directly placed in the heating equipment such as muffle furnace, and temperature rise is realized by heat radiation and natural convection. However, this scheme has the following technical defects:

[0003] 1. Uneven heat field distribution

[0004] Under the static heating mode, significant axial and radial temperature gradient is formed in the reaction kettle:

[0005] · The local temperature of the region near the heating source is over threshold value due to concentrated heat radiation (the highest temperature difference is up to ± 50 DEG C measured by experiment);

[0006] · The cold zone is formed in the reaction material accumulation area due to blocked heat conduction, leading to inconsistent reaction kinetics (such as abnormal grain growth, active component distribution deviation).

[0007] Such unevenness directly affects the product performance and increases the risk of side reaction.

[0008] 2. Low mass transfer efficiency

[0009] Under the static state, the reaction material only relies on natural diffusion or limited convection to realize mixing, and the following problems exist:

[0010] · Particle agglomeration and sedimentation: high-density or large-particle material is easy to accumulate on the bottom of the kettle, leading to more than 50% reduction of effective contact area;

[0011] · Low energy utilization rate: energy is wasted significantly in the local overheated area (30%-40% of the total energy consumption of the system), and the cold area needs to extend the heating time for compensation.

[0012] Experimental data show that the reaction time of static heating under the same condition is about 2-3 times of that of dynamic heating mode.

[0013] 3. Limited equipment applicability

[0014] The prior art scheme has the following structural contradictions:

[0015] · Poor material form adaptability: easy to cause bridging and wall sticking for non-uniform materials such as slurry and powder;

[0016] · Scale bottleneck: large reaction tanks are difficult to efficiently invert due to their weight and inertia, while small tanks cannot meet the needs of industrial continuous production.

[0017] The above defects result in that the prior art is difficult to meet the needs of high-end manufacturing in terms of reaction controllability (such as temperature uniformity within ±10℃), production efficiency (output per unit time), and product consistency (batch difference CV value ≥15%).
