Lignite dryer structure and characteristics
Structure: the main component of lignite dryer are: pulverizer, conveyor, heat source equipment, rotary dryer, the feeder dust removal equipment, temperature control device, electrical system, etc.
Features: lignite belongs to a kind of coal, coal's degree of coalification just above the coal slurry, it is a kind of between peat and bituminous coal in brown black, matt lean coal. Lignite are rich in volatile matter, so it is easy to burn and smoke. At the same time lignite has prominent features: high moisture (general moisture content in 32 to 42%), volatile matter high (general between 40 and 50%), low calorific value (general average calorific value in 3000 kilocalorie below), low density, low ash fusion point. Based on the above reasons lignite is difficult to be widely used as industrial power coal, therefore lignite economic value is not the biggest reflect. In the present tense global energy situation, the economic value of lignite is paid attention to by the world energy bound. lignite drying carry mass technology development and application is lignite large-scale industrial application basis and conditions. cowin machinery research and development lignite dryer adopt scientific technology and advanced equipment for coal drying in addition to water, improve coal economic value, promote the lignite resource saving energy development and widely used.
Performance advantage
1. Drying cost minimization.
Lignite dryer of insulation taken measures to reduce heat loss. With low cost of coal as a heat source fuel, reduce fuel expenses. Lignite drying equipment full automation reduce human cost input.
2. Dry production safety maximization.
Lignite drying equipment full automation flameproof explosion protection, put an end to the production accidents. Field construction by skillful and experienced technical construction personnel, to ensure that equipment and stable operation. One year free warranty, life-long maintenance, to ensure that you do not have trouble back at home.
3. Drying product quality is good.
Lignite dryer uses three layer settling structure, reduce dust contamination to the materials. High temperature rapid process to reduce material of organic element loss. Online moisture control, fuzzy control, make drying material water uniform.
4. Dry strength.
Lignite drying equipment every hour to water highest can amount to 8000 kg, continuous production uninterrupted.
5. Drying efficiency is high.
Lignite dryer USES high temperature rapid drying process, hot air temperature utilization rate than ordinary low temperature drying method and thermal efficiency is increased by 40%, thermal efficiency is as high as 90% of the heat source system, make comprehensive thermal efficiency as high as 73%. Part of the dry hot air by end into the head end to continue heating, reduce heat loss.
