Embodiment Construction
[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

The invention relates to a ventilating structure which comprises a cylinder and a ventilating plate. The ventilating structure is provided with vent holes which include the first vent holes penetrating through the cylinder, and the second vent holes penetrating through the ventilating plate. The second vent holes are communicated with the first vent holes. The total cross sectional area of the second vent holes is larger than the total cross sectional area of the first vent holes. The invention further discloses a radial reactor which comprises an outer cylinder, a radial reaction basket and a first gas collecting tube. The ventilating structure is adopted for the radial reactor and / or the first gas collecting tube. In the ventilating structure and the radial reactor, gas firstly enters the first vent holes and then further dispersed through the second vent holes with larger sectional area after being dispersed, the effect of dispersing gas is achieved, gas is evenly distributed, reaction is more uniform and sufficient, it is ensured that reaction gas in a reaction bed layer can be uniformly distributed and uniformly flow in the height direction and the circumferential direction, and it is avoided that catalytic agent is burnt out by local ultrahigh temperature in a gas dead zone.
Description
technical field [0001] The invention relates to the technical field of chemical engineering, in particular to an aeration structure and a radial reactor used in ammonia synthesis and methanol synthesis production. Background technique [0002] The methanol synthesis reaction is a strongly exothermic reversible reaction, the main reaction formula [0003] CO+2H 2 =CH 3 OH+ΔH R1 [0004] CO 2 +3H 2 =CH 3 OH+H 2 O+ΔH R2 [0005] ΔH R1 =-76519.5-49.2909T----------P132 [0006] ΔH R2 =-37858.2-22.666T-------P132 [0007] The reaction is carried out in a reactor equipped with a catalyst. The modern methanol catalyst is a low-pressure low-temperature copper-zinc-aluminum system with a pressure of 4.0MPa-8.5MPa and a temperature of 210°C-280°C. It can be seen from the above that the unreacted gas must be preheated to 210°C. During the reaction process, the heat release is large and the temperature rises greatly. For example, the temperature rises by 32°C for every 1% C...
