Chemical reactor

Abstract

The invention discloses a chemical reactor, comprising a reactor tank body for loading reactants and a catalyst, wherein the upper part of the reactor tank body is provided with a feed pipe, the lower part thereof is provided with a discharge pipe; a catalyst / reactant separator is arranged at the lower part of the inner cavity of the reactor tank body and is composed of a mounting plate; the mounting plate is provided with mounting holes alternatively, and water caps are arranged in the mounting holes and comprise screwed pipes matched with the mounting holes; and filter vats are arranged on the upper parts of the screwed pipes, and the surface of the filter vat is of a meshed structure of which the clearance is smaller than the diameter of the catalyst. Only by processing the mounting holes with large diameter on the mounting plate, steel plates with larger thickness can be used as the mounting plates so as to satisfy the requirement of high bearing capacity and facilitating processing of the mounting plate; and the meshed structure on the surface of the water cap can completely satisfy the separation requirement of the catalyst and the reactants, thus taking the bearing capability and filtering effect into account simultaneously, and conforming to the special requirements for the reactor.

Description

[0001] technical field [0002] The invention relates to a chemical reactor, in particular to a chemical reactor suitable for producing nonylphenol, and of course it can also be adapted to a reactor for producing other compounds. Background technique [0003] Chemical reactor (reactor) is a kind of equipment to realize the reaction process, which is widely used in chemical industry, oil refining, metallurgy, light industry and other industrial sectors. It is mainly used to realize liquid-phase single-phase reaction process and multi-phase reaction process such as liquid-liquid, gas-liquid, liquid-solid, gas-liquid-solid, etc. There is always a stirring (mechanical stirring, airflow stirring, etc.) device in the reactor. When the ratio of height to diameter is large, multi-layer stirring blades can be used. When the reactants need to be heated or cooled during the reaction, a jacket can be installed on the reactor wall, or a heat exchange surface can be installed inside the...

Problems solved by technology

This kind of sieve plate is simple in structure and practical, and is suitable for most reactors, but it also has inherent defects. For example, in order to improve the yield or reaction efficiency, some reactors have a larger volume and can be filled with more catalysts, so sieves are required. The larger the thickness of the plate, the heavier the catalyst and material can be carried; when the diameter of the catalyst is smaller, it is necessary to drill smaller holes on the sieve plate, but from the perspective of machining, the thicker steel plate It is very difficult to drill holes with smaller diameters. For example, a nonylphenol reactor needs to drill Φ2.5mm holes on a Φ1.6-meter sieve plate, and the sieve plate needs to carry 5 tons of the reactor. The reactants and catalysts should not be too thin, which makes it very difficult to manufacture sieve plates that meet the requirements
