Embodiment Construction

[0047] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the scope of protection of this application.

[0048] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may be another element in between. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or it may be present inte...

Abstract

The invention discloses a fluid mixing device. The fluid mixing device comprises a reaction container; the interior of the reaction container is used for a first fluid to flow; the fluid mixing devicefurther comprises a plurality of nozzles for ejecting a second fluid into the reaction container, wherein the plurality of nozzles are distributed along a circumferential direction of the reaction container; the spraying direction of each nozzle deviates from the nozzle and a center connection line of the reaction container; and included angles between the spraying directions of at least two nozzles and the nozzles and the center connection line of the reaction container are equal. The fluid mixing device has a simple structure and good mixing performance and distribution performance, is convenience for installation and maintenance, can reduce pressure drop in the device, and can reduce cost.

Description

technical field [0001] The application relates to the technical field of material mixing and heat exchange in chemical engineering or petroleum processing, and in particular to a fluid mixing device. Background technique [0002] Ethylbenzene is an important chemical raw material mainly used to supply the downstream material industry. It is mainly obtained through the strong exothermic reaction of benzene and ethylene under relatively high temperature and high pressure conditions. An effective production process for the preparation of ethylbenzene is as follows: using a fixed-bed reactor with multi-stage feed, using the dry gas rich in ethylene components discharged during the catalytic cracking of petroleum as a raw material, and benzene steam under relatively harsh conditions For gas phase reaction, ethylbenzene is obtained. [0003] The fixed-bed reactor used in the above-mentioned production process refers to a reactor in which the fluid flow mode is parallel and downwa...
