Description

Technical Field

[0001] The present application relates to the field of reactors, and in particular to a uniform temperature fixed bed reactor. Background Art

[0002] Fixed bed reactor refers to a reactor filled with granular solid catalysts or solid reactants to form a stacked bed of a certain height. Gas or liquid materials flow through the static fixed bed through the gaps between particles, realizing a heterogeneous reaction process. The characteristic of this type of reactor is that the solid particles filled in the equipment are fixed, which is different from the moving bed and fluidized bed in which the solid materials move in the equipment. It is also called a packed bed reactor. Fixed bed reactors are widely used in gas-solid phase reaction and liquid-solid phase reaction processes, for example, fixed semi-water gas generators in the synthetic ammonia industry, fixed bed ion exchange columns in water treatment, etc. Trickle bed reactors can also be classified as fixed bed reactors. The gas and liquid phases flow downward through the bed layer in parallel, forming gas-liquid-solid contact.

[0003] Under the natural state, the current fixed bed reactor causes the reaction inside the fixed bed reactor to be too slow and cannot process more liquid in the same time.

[0004] In this regard, the Chinese patent application number is CN202023333249.4, which discloses a fixed bed reactor, including a reaction barrel, a fixed bed layer, a discharge pipe, a material receiving box, a heating layer, multiple groups of heating elbows, multiple groups of electric heating pipes, an oil inlet, an oil discharge port, a barrel cover and a first filter screen. The top of the reaction barrel is connected to the bottom end of the barrel cover, and a feed hopper is provided at the top of the barrel cover. The first filter screen is located in the feed hopper. A reaction chamber is provided in the reaction barrel, and positioning rings are provided in the upper and lower regions of the reaction chamber. The fixed bed layer is located in the reaction chamber, and two groups of positioning rings are respectively connected to the top and bottom ends of the fixed bed layer.

At the same time, the raw materials always fall in one place, and materials at other positions of the fixed bed layer enter unevenly, thus affecting the reaction quality and reducing the practicability of the device.
