Embodiment Construction

[0022] In the integrated reaction and separation equipment provided by the present invention, the main catalytic reaction process occurs in the ring pipe 1. The ring pipe 1 includes upper and lower horizontal sections and vertical sections, and the upper and lower horizontal sections limit the flow of the upper and lower horizontal reaction materials. Each section is connected to the adjacent section by means of a smooth elbow or elbow. The diameter and length of the ring pipe 1 (including the number of upper and lower horizontal sections and vertical sections, etc.) depends on the specific reaction production capacity, reaction residence time, etc. Depending on time and productivity requirements, ring pipes can be machined from steel, titanium, nickel or other alloys.

[0023] The circulation pump 3 on the loop pipe 1 provides energy to circulate the reaction material in the loop pipe 1. The circulation pump 3 can be installed at an appropriate position in the loop pipe 1. The...

Abstract

The present invention provides an integral reaction-separation equipment, mainly comprising a ring pipe and a separation component, wherein a circular reaction circuit is formed by the ring pipe and the separation component. The equipment is compact in structure, integrates catalytic reaction with catalyst separation and material heat transfer, especially can guarantee the high efficiency separation and the recycling use of fine particles such as nanometer or micron catalyst with reacting materials, and has good material mixing and heat transferring effects, which is suitable for strong heat absorbing or releasing solid-liquid, solid-liquid-liquid and partial gas-liquid-solid multiphase reaction system.

Description

technical field [0001] The invention relates to a chemical equipment, more specifically to an integrated equipment composed of catalytic reaction, product and catalyst separation and material heat exchange. Background technique [0002] In the field of petrochemical production, there are many chemical reaction processes that not only use solid catalysts, but also are accompanied by strong exothermic reactions. In order to avoid the generation of hot spots in the reaction system and keep the temperature uniform, the operation method of catalyst suspended in the liquid can obtain a relatively satisfactory effect. Due to the large heat transfer coefficient of the liquid, the suspension operation of the catalyst in the liquid is easy to recover heat; the catalyst particle size used in this method is small, so there is no need to granulate the catalyst, and there will be no significant utilization of the inner surface of the catalyst It is beneficial to the application of high-a...
