Problems solved by technology

The fluidized bed has to go through a heating and cooling process in the drying process of each batch, which is a serious waste of energy. At the same time, the batch fluidized bed has a small output and cannot be large-scaled. The labor intensity of the workers is high, and the water content of the product is easy to fluctuate.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] In Fig. 1, the heat source of the drying system adopts hot air, and the first-stage drying: the wet material is fed into the pulse air dryer 14 by the conveying auger 15, and the dry air is filtered through the 2# air filter 17, and exchanges heat with the 5# steam The high-temperature air exchanged by the device 16 is fully contacted, and the material is initially dried in the pulse airflow dryer 14, and enters the fluidized bed dryer 8 through the respective corresponding air shutoff devices 18 at the bottom of the cyclone dust collector II12 and cyclone dust collector I13, and the exhaust gas passes through the fluidized bed dryer 8. After the induced draft fan 11 is pressurized, it is emptied by the evacuation pipe.

[0022] Secondary drying: The material after primary pre-drying is fed into the fluidized bed dryer 8 through the air locker 18...

Abstract

The present invention discloses one chlorinated polyethylene drying process. The chlorinated polyethylene drying process with hot air as drying medium includes the first stage of pulse airflow drying and the second stage of fluidized bed drying to dry chlorinated polyethylene with 30-55 % water content into product with 0.3 % below water content. The present invention has simple drying apparatus, high heat efficiency, low water content in product and other advantages.

Description

technical field [0001] The invention relates to a drying process, in particular to a chlorinated polyethylene drying process. Background technique [0002] As we all know, when chlorinated polyethylene is dried, hot air is used as the drying medium. At present, intermittent fluidized bed is usually used for drying. Intermittent fluidized bed adopts batch drying method. Cooling, discharging and other processes. The fluidized bed has to go through a heating and cooling process in each batch of drying process, which is a serious waste of energy. At the same time, the output of the batch fluidized bed is small, and it cannot be enlarged. The labor intensity of the workers is high, and the water content of the product is easy to fluctuate. Contents of the invention [0003] The object of the present invention is exactly to overcome above-mentioned deficiencies in the prior art, provide a kind of chlorinated polyethylene drying process that has advantages such as thermal effici...
