Embodiment 1

[0025] In the technical solutions disclosed in one or more embodiments, such as Figure 1-4 Shown, a kind of spray granulation device that is applicable to high-concentration calcium chloride solution includes one or more two-fluid nozzles 7, purging device, atomizing gas device and feed liquid supply device, described purging device, mist The gasification device and the material-liquid supply device are respectively connected to the dual-fluid nozzle 7; the control purge device and the atomizing gas device are connected to the dual-fluid nozzle 7 to realize interval purging and continuous atomization.

[0026] In this embodiment, the dual-fluid nozzle and the purging device are installed at the same time, so that the pressure requirement of the feed liquid required by the spray granulation device is low, and the requirements for the upstream feed liquid pump are low, and the spray liquid atomization angle can be large, and the nozzle nozzle is not easy to hang. The nozzle is ...

Embodiment 2

[0054] Based on embodiment 1, this embodiment provides a kind of atomization method, comprises the following steps:

[0055] Start the air compression device and the material liquid delivery device for atomization;

[0056] Periodically turn on the purge device according to the set time interval, so that the purge gas enters the dual-fluid nozzle 7 for purging, and at the same time heats the feed liquid channel 1 of the dual-fluid nozzle;

[0057] After the atomization is completed, close the air compression device, material liquid conveying device and purging device.

Abstract

The invention provides a spray granulation device and an atomization method suitable for a high-concentration calcium chloride solution, the spray granulation device comprises one or more double-fluid nozzles, a purging device, an atomization gas device and a feed liquid supply device, and the feed liquid supply device is connected with the double-fluid nozzles; the control purging device and the atomization gas device are connected with the double-fluid nozzle, and interval purging and continuous atomization are achieved. According to the device disclosed by the invention, the double-fluid nozzle and the purging device are arranged at the same time, so that the atomization effect of the spray granulation device can be greatly improved, and the atomization efficiency is improved.

Description

technical field [0001] The present disclosure relates to the technical field of atomization device and control, in particular, it relates to a spray granulation device and an atomization method suitable for high-concentration calcium chloride solution. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Calcium chloride product specifications mainly include calcium chloride dihydrate and calcium chloride anhydrous, and the product appearance has three types: flake, spherical and powder. Among them, spherical calcium chloride has the advantages of beautiful appearance, good fluidity, not suitable for moisture absorption and hardening, and is expected to become the mainstream variety of calcium chloride products. [0004] The inventors found that the performance characteristics of the calcium chloride solution make the nozzle spouts in the sp...
