Abstract
Description
The present invention | Traditional drying technology | |
Drying mode | Closed circuit nitrogen circulation steam pipe rotary drying | Open circuit air heat fluidized bed drying |
Technological process | Nitrogen washing---moisture from, cool nitrogen---moisture is from, nitrogen supercharging, heating process | Hot gas ebullated, I and II separates |
Product quality | Free from admixture, good quality of product | Because of air carries impurity, influence product quality |
Processing safety | Do not have | Partial combustion or explosion accident occurred repeatedly, there is potential safety hazard in production |
Public work consumes | : the heat that 47.45KW is required: 229055Kcal/h nitrogen: 50Nm 3/h | : the heat that 140KW is required: 450715Kcal/h |
Operating cost | : 18.80 (unit/ton product) steam: 24.50 (unit/ton product) nitrogen: 9.00 (unit/ton product) operating cost adds up to: 52.30 (unit/ton products) | : 55.48 (unit/ton product) steam: 48.20 (unit/ton product) operating cost adds up to: 103.68 (unit/ton products) |
