Abstract

The invention discloses a load plug-in of a superfine fiber electrostatic adsorption catalyst and a use method of the load plug-in. The load plug-in mainly comprises a mercuric chloride catalyzing particle, an electro-adsorption superfine fiber membrane layer, a catalyst load layer and a static isolating layer, the catalyst load layer covers the surface of the mercuric chloride catalyzing particle, the static isolating layer covers the surface of the catalyst load layer, the electro-adsorption superfine fiber membrane layer is wrapped on the outermost layer, and electro-adsorption superfine fiber membrane electric terminals are arranged at the two ends of a tube plate flange. In the use process, the plug-ins are sequentially arranged in a heat exchanger, the two ends of the tube plate flange are powered on with a direct current power supply, the electro-adsorption superfine fiber membrane electric terminals are arranged at the two ends of the tube plate flange, so that an electric conduction fiber membrane contains even electric charges, finally the mixed gases are introduced into the heat exchanger filled with the mercuric chloride catalyst plug-in, and the gases react with the catalyst when passing through catalyst plug-in. According to the load plug-in of the superfine fiber electrostatic adsorption catalyst and the use method of the load plug-in, the use efficiency of the catalyst is improved, the reaction speed is increased, and the mercury contamination and treatment are also reduced.

Description

technical field [0001] The invention relates to a loading insert for an electrostatic adsorption catalyst of an ultrafine fiber membrane and a method for using the same, belonging to the field of industrial application of the ultrafine fiber. Background technique [0002] In the current chemical production, catalysts are used in the preparation of many products, and the cost of catalysts is relatively high, which leads to an increase in the production cost of products. Catalyst particles will be broken into ultra-fine particles during the reaction process, which is especially easy to escape and lose with the gas reaction products. On the one hand, it will cause low catalyst efficiency and cause various environmental problems. It is urgently required to reduce the loss of catalyst in the reaction process, improve the reaction efficiency and reduce the amount of catalyst in the chemical production process.

AI Technical Summary

Problems solved by technology

The consumption of mercury element is divided into three parts in this process: the first part is that the high water content in the reaction gas causes mercury chloride to form mercury ions when it encounters water; the second part is that mercury chloride catalyst particles are broken and lead to the loss of mercury with dust particles ; The third part is that in the reaction process, the contact between the reaction gas and the catalyst is insufficient, which leads to the need to increase the reaction temperature to promote the reaction in the later stage of the reaction. Increasing the temperature will cause the sublimation of mercuric chloride and cause mercury to be consumed

[0006] The main problems faced by enterprises in production are the serious loss of mercury chloride catalyst and the complexity of the mercury removal process in subsequent products. These problems lead to high production costs of PVC.
