Production equipment for aluminium triethyl

Abstract

The invention discloses production equipment for aluminium triethyl, which belongs to the field of petrochemical equipment, in particular to equipment provided with a quantitative discharging structure and equipment provided with a hexane heat-removing structure by changing the structure of a reaction kettle. The production equipment comprises a reaction kettle, wherein the reaction kettle is provided with the quantitative discharging structure in which a preset diameter and a liquid level line are set in the reaction kettle and in which a quantitative discharging pipe is arranged at the liquid level line. In the technical scheme, quantitative discharge is controlled precisely, the primary amount of seeds is controlled effectively, the equipment is simplified, danger chances in a production process are reduced effectively and the hexane heat-removing structure arranged in the reaction kettle is optimized. The hexane heat-removing structure is reasonably arranged in the reaction kettle, namely a coil pipe is arranged in the body of the reaction kettle, wherein the input end of the coil pipe is connected with an output end of a hexane storage tank; and the output end of the coil pipe is connected with an input end of the hexane storage tank. When entering the coil pipe of the reaction kettle, hexane is heated by the heat generated by a reactant in the kettle body and is then vaporized. The hexane in the coil pipe absorbs reaction heat in the process of the conversion to a gaseous phase from a liquid phase, so that a hexane radiation effect is achieved.

Description

technical field [0001] The invention belongs to the field of petrochemical equipment, and in particular relates to production equipment of triethylaluminum. The equipment with quantitative discharge structure and the equipment with hexane heat removal structure are formed by improving the structure of a reaction kettle. Background technique [0002] The production of triethylaluminum is an existing technology, such as the commonly known "two-step method" process: first mix triethylaluminum seeds and aluminum powder in a seed metering tank and then transfer them to a reaction kettle, and hydrogen is introduced into the kettle for hydrogenation reaction to generate diethylaluminum hydride, then all the reaction solution is transferred to the ethylation reactor and ethylene is added for ethylation reaction to generate triethylaluminum crude product, and 84%-85% of the product generated by each kettle is returned to After adding aluminum powder into the seed metering tank and mi...

Problems solved by technology

[0006] The published Chinese patent "00819839.X crystallization and refining device and method", although related to the feeding technology in the production process of chemical products, can not solve such problems: when the aluminum powder is put in, due to the sticky characteristics of the aluminum powder itself and the There is usually a slight positive pressure in the reaction kettle, which makes the feeding of aluminum powder always difficult, which makes feeding difficult, and easily causes the danger of flammable gas leakage;

[0009] In addition, the reaction heat removal process and equipment in the reactor are not optimized enough, etc. Therefore, the industry urgently needs a production equipment for triethylaluminum with simpler equipment, simpler operation and higher safety.
