Problems solved by technology

[0013] Among the above-mentioned inventions, the liquid-gas type continuous flow reactor, the hydrogen chloride injection reactor, the tubular reactor and the spray reactor equipped with fillers can meet the requirement of increasing the sufficient contact between gas and liquid, but it is difficult to meet the requirement of long reaction residence time. specialty
Tank reactors and bubbling reactors can meet the characteristics of long residence time of the reaction liquid, but the traditional agitator cannot meet the requirements of multi-stage contact between gas and liquid

Abstract

The invention provides a rotational flow plate glycerinum chlorination bubbling reaction tower which comprises a tower body, wherein the tower body comprises a plurality of rotational flow plates in a combined manner; the diameter of a sieve pore in each rotational flow plate is 3-20 mm; the trepanning directions of the upper parts of the sieve pores rotate clockwise or anticlockwise; the angle of a chamfer at the bottom of the sieve pore in the rotational flow plate is 5-85 degrees; a plurality of gas distribution pipes are arranged at the bottom of the tower body; open pores of gas distribution pipes are formed in the gas distribution pipes; each open pore and the horizontal line form an angle of 0-75 degrees; the diameter of the open pore is 0.5-20 mm. The invention further provides a device for producing epichlorohydrin and a use method of the device, wherein the device is composed of three levels of rotational flow plate glycerinum chlorination bubbling reaction towers which are connected in series, so that the floor area of the traditional reaction kettle is effectively saved, a liquid phase reactant is in better contact with a gaseous phase reactant, the reaction time is saved, the reaction efficiency is high and the productive rate is increased.

Description

technical field [0001] The invention belongs to the field of production of epichlorohydrin and dichloropropanol, and in particular relates to a swirl plate glycerin bubbling reaction tower, a device for producing epichlorohydrin and a method for producing epichlorohydrin by using the device. Background technique [0002] Epichlorohydrin (alias epichlorohydrin), the chemical name is 1-chloro-2,3-epoxypropane, and the molecular formula is C 3 h 5 OCl, with a boiling point of 115.2°C and a freezing point of -57.2°C, is a volatile and unstable colorless liquid, slightly soluble in water and miscible with various organic solvents. [0003] Epichlorohydrin is an important organic chemical raw material and fine chemical product. It is a large variety of propylene derivatives. It is mainly used in the synthesis of glycerin, epoxy resin, epichlorohydrin rubber, nitroglycerin explosives, etc. It can also be used It is used as a solvent for cellulose esters, resins and cellulose ethe...
