Anti-corrosion reaction kettle for producing p-dichlorobenzene

Abstract

The invention discloses an anti-corrosion reaction kettle for p-dichlorobenzene production, and relates to the technical field of chemical production. The anti-corrosion reaction kettle comprises a shell. A base matched with the shell is arranged at the bottom of the shell; a ball screw is arranged at the top of the shell in a penetrating mode; a rotating disc is fixedly connected to the top of the ball screw; a flow limiting pipe is fixedly connected to the bottom of the rotating disc; the bottom end of the flow limiting pipe penetrates through the top of the shell and extends to an inner cavity of the shell; pressure measuring devices are embedded in the two sides of the inner cavity of the shell correspondingly; and baffles are movably connected to the two sides of the top of the base through rotating shafts correspondingly. According to the anti-corrosion reaction kettle for p-dichlorobenzene production, through improvement of the pressure measuring devices and cooperative use of the ball screw, the flow limiting pipe, the baffles, limiting nuts, a heat conduction plate and other components, leakage of chemical raw materials in the reaction kettle and relatively low chemical reaction degree caused by a too large internal and external air pressure difference are avoided.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to an anti-corrosion reaction kettle for the production of p-dichlorobenzene. Background technique [0002] The broad understanding of the reactor is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. The reactor is widely used in petroleum, chemical, Rubber, pesticides, dyes, medicines, food, and pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, and condensation. Reactors are used as reaction vessels in the production process of p-dichlorobenzene. [0003] Traditional reactors are prone to leakage of chemical raw materials inside the reactor and relatively low degree of chemical reaction due to excessive pressure difference be...
