Problems solved by technology

Due to the particularity of its own reaction conditions, during the reaction process, the gas reacts with the liquid in the contact process. Due to the difference in physical properties between the two, the gas rises linearly in the liquid. During the reaction, the gas accumulates in the In the upper part of the reactor, the contact time between the gas and the liquid is short, which eventually leads to the incomplete reaction of the two.
[0003] The general method used in the market is to stir the liquid, and the liquid forms a vortex in the kettle to increase the contact area between the gas and the liquid and improve the reaction efficiency of the two. The reaction only occurs at the position where it is in contact with the liquid, and the gas at the top of the reactor is difficult to completely react, and the reaction efficiency is low
[0004] After further improvement by technicians, by adding a return line, the gas at the top of the reactor shell is returned to the liquid at the bottom of the reactor through the pump group, and the contact time between the gas and the liquid is further increased by means of continuous reflux. Reaction efficiency, but the reaction mechanism of this kind of reaction is that a small amount of gas is continuously fed into a large amount of liquid medium. Obviously, the liquid medium is excessive. For some reversible reactions or reactions with high material ratio precision, not only Lead to the occurrence of side reactions and other side reactants at the same time, the device as a whole cannot control the accuracy of the reaction

Abstract

The invention discloses an efficient chemical solid-liquid reaction kettle. The reaction kettle is a cylindrical shell. A cylindrical guide cylinder is arranged in the middle of the shell. A liquid distributing device and a gas flow jetting device are arranged in the guide cylinder. The liquid distributing device comprises a guide plate, a connecting shaft and a liquid discharge tube. The gas flow jetting device comprises a gas guide tube and a gas flow jetting propeller. The guide plate is arranged on the lower portion of the connecting shaft, and the liquid discharge tube is arranged at the connection of the connecting shaft and the guide plate. The gas flow jetting propeller is arranged at the top of the gas guide tube. An arc-shaped groove protruding outwardly is formed in the middle of the guide cylinder. The horizontal height of the arc-shaped groove is identical with the mounting height of the gas flow jetting propeller. The guide cylinder above the arc-shaped groove is conical. The efficient chemical solid-liquid reaction kettle has the advantages that the contact area of gas media and liquid media is increased to the maximum extent by the specially-produced guide cylinder coordinated with the liquid distributing device and the gas flow jetting device, the gas media and the liquid media sufficiently contact in the guide cylinder to maximally promote the reaction, and the reaction kettle is simple in structure and convenient to mount and demount.
