Air-cooling prilling tower

Abstract

The invention discloses an air-cooling prilling tower. The air-cooling prilling tower comprises a tower body, an air inlet pipe, an air outlet pipe, a liquid inlet pipe, a discharge pipe and a separation pipe; the air inlet pipe is arranged at a lower end center location of the tower body, an upper end of the air inlet pipe extends into the tower body, and one end of the liquid inlet pipe extendsinto the tower body and extends to an upper end air outlet of the air inlet pipe; the lower end of the tower body is connected with the discharge pipe, and the separation tube is arranged in the middle of the discharge pipe in an inclination manner; one end of the separation pipe is arranged on the discharge pipe, the other end is arranged on the air inlet pipe, and the air outlet pipe is arranged in the middle of the upper end of the tower body; the liquid inlet pipe and the air inlet pipe are not arranged together, so that the air inlet pipe has sufficient wind force to enter the tower body, the prilling effect is good, the separation pipe communicates with the air inlet pipe, and the air inlet pipe can produce a certain draft for the separation tube when inletting the air, the powder in the discharge pipe can be sucked into the air inlet pipe, the separation work can be accomplished without adding the other device, and the production cost and the use cost are reduced.

Description

technical field [0001] The invention relates to the technical field of magnesium chloride granulation equipment, in particular to an air-cooled granulation tower. Background technique [0002] Industrial magnesium chloride is a mixture of MgCl2 4H2O and MgCl2 6H2O. It is used in the chemical industry to produce various magnesium salt products. The brine produced by seawater drying salt contains more magnesium chloride. In order to extract magnesium chloride, the commonly used equipment is Air-cooled granulation tower, the liquid inlet pipe of the existing air-cooled granulation tower is set in the air inlet pipe, which will make the wind force insufficient and cannot meet the air-cooling requirements well, and the original equipment configuration structure is relatively Complicated and expensive to produce and use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an air-cooled prilling tower with a simple structu...
