Abstract

The invention discloses a cooling granulating tower for melts comprising a main tower, an atomizer fixed on the top of the main tower, and a cold air intake system. The air intake system comprises a blower, a condenser and a volute casing connected in series, and the volute casing is disposed on the bottom of the main tower. The atomizer is a centrifugal atomizer. By using the air intake volute casing, a counter-current operation relation is shown between the product and the cold air in the tower, the heat exchange time between the product and the cold air in the tower is greatly reduced, so that the height of the cooling granulating tower is reduced. By using the centrifugal atomizer, the cooling granulating tower has large throughput and is easy to adjust, the product has good particle roundness, and the particle size of the product can be changed by adjusting a frequency converter, the pore diameter of a meshed disc and so on.

Description

technical field [0001] The invention relates to a cooling prilling tower, in particular to a cooling prilling tower used for melts. Background technique [0002] The existing cooling granulation tower has the following disadvantages in the actual production and production process: 1. The material and the cold air are operated downstream, the heat exchange process time is shorter, and the height of the tower body is increased, which increases the investment cost. 2. The product molding is poor. Under the action of high pressure and high centrifugal force, the feed liquid splits into extremely fine droplets, and after cooling, there are a large number of powdery and broken shapes, and rarely spherical particles. Contents of the invention [0003] The object of the present invention is to provide a cooling and prilling tower with a short tower body and good material formation in view of the above-mentioned problems. [0004] The technical scheme adopted in the present inven...
