Abstract

The invention discloses chemical production equipment and a use method, the chemical production equipment comprises a fixed bed reaction device and a dehydration device, and the fixed bed reaction device is connected with the dehydration device through a conduit; wherein the fixed bed reaction device comprises at least two input pipelines, a reaction furnace, a first condenser and a collector, theinput pipelines are connected with an inlet of the reaction furnace, an outlet of the reaction furnace is connected with the collector through the first condenser, and an outlet of the collector is connected with an inlet of the dehydration device; an outlet of the fixed bed reaction device is connected with a raw material tank, the raw material tank is connected with a membrane assembly throughan inlet pipe and an outlet pipe, the raw material tank and the membrane assembly are arranged in a heating cavity, the membrane assembly is of a cylindrical structure internally provided with a pervaporation membrane, and the membrane assembly is connected with a vacuum assembly and a second condenser; according to the invention, the pervaporation membrane is adopted to carry out the dehydrationprocess, so that the continuous operation from the reaction process to the dehydration process can be realized, the chemical production efficiency is greatly improved, and meanwhile, the pollution orloss in the raw material transfer process is avoided.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a chemical production equipment and a use method. Background technique [0002] Fixed bed reactor, also known as packed bed reactor, is a reactor filled with solid catalyst or solid reactant to realize heterogeneous reaction process. The solids are usually granular, with a particle size of about 2 to 15 mm, and are piled up into a bed of a certain height (or thickness). The bed is stationary and the fluid passes through the bed to react. The difference between it and the fluidized bed reactor and moving bed reactor is that the solid particles are in a static state. Fixed bed reactors are mainly used to realize gas-solid phase catalytic reactions, such as ammonia synthesis towers, sulfur dioxide contact oxidizers, hydrocarbon steam reformers, etc. When used in gas-solid or liquid-solid non-catalytic reactions, the bed is filled with solid reactants. The trickle bed...

Problems solved by technology

[0004] Generally, for chemical equipment with reaction process and dehydration process at the same time, in order to facilitate the addition of materials such as catalysts in the dehydration process, the reaction process and the dehydration process are generally carried out through two independent equipment, and the dehydration process is carried out manually. In this way, the raw materials produced in the reaction process are added together with catalysts, so continuous production cannot be realized. During the transfer of raw materials between the two devices, it is easy to cause volatilization of raw materials and other situations.
