Inert medium spray-atomizing-drying machine by vibration

Abstract

This invention relates to an atomized drying machine with vibrating inert medium, in which, the tower of which is a cylindrical drum, a fluid pipe and a pressure nozzle are mounted on top of inside of the drum, a hot air port is opened at the bottom of the drum and a discharge port is opened on the top characterizing the up and down ends of the drum are conic structure, two titled vibration motors in opposite direction are set at both sides of the drum, an isolation net is set at the lower taper drum with inert medium on it, which applies a double-vibration motor to avoid materials adhered on the wall and adds inert gas to increase drying degree and speed up the drying speed.

Description

technical field [0001] The invention belongs to the technical field of spray drying, in particular to a vibrating inert medium spray atomizing dryer. Background technique [0002] With the rapid development of the national economy, there are more and more types and quantities of dilute materials that need to be dried in various industries. In the traditional single spray drying equipment, only the liquid pipe and the pressure nozzle for atomization are installed in the drying tower. The cylinder of the drying tower is long, and the spray particles fall in the drying tower almost automatically. There are following defects in the working process: [0003] 1. The transmission momentum is small and the drying rate is low. The dried mist particles are in contact with the hot air in the drying tower to perform heat transfer and mass transfer exchange, but the water content of the mist particles is very high, which requires a long drying time. Therefore, the droplet particles in...

Problems solved by technology

[0004] 2. Low drying strength and low heat transfer coefficient

The particles of the liquid to be dried are in contact with the hot air, and only a single convective heat transfer is performed, so that the heat transfer and mass transfer coefficients are small, and the drying strength per unit space is low

[0005] 3. The equipment is huge, the energy loss is large, and the equipment investment is high

Spray drying must ensure that the droplet movement has enough landing height and space to ensure the quality and quantity requirements of the product. The equipment is huge, the heat dissipation area is increased, the heat loss is large, and the investment in infrastructure and equipment is high, causing many users to be unable to purchase.
