Technical field
The invention belongs to low-order coal drying and upgrading technical field, particularly relate to a kind of polynary drying device of vibratory liquefaction microwave for low-order coal upgrading.
Background technology
According to incompletely statistics, the low-order coal such as global brown coal, jet coal account for 40% of coal gross reserves, and low-order coal, compared with other coals, has that volatile matter is high, at the bottom of calorific value and the characteristic such as moisture is high.The low-order coal resource of rich reserves is fully utilized, there is important social value and economic worth.
Because the water content of low-order coal is high, just can utilize after must processed being carried out, and the process of the dehydration process of low-order coal i.e. drying and upgrading, low-order coal is after drying and upgrading, and the most direct effect is exactly the calorific value that improve coal.
At present, low-order coal is mainly drum-type drying, but the mixed thermal efficiency of this drying mode is lower, and drying time is long.Efficiency is dehydrated in order to what improve low-order coal, there is large-scale vibrating fluid-bed drying technology thereupon, although the low-order coal treating capacity of this technology is large, but in low-order coal dry run, still cannot ensure the dry completeness of low-order coal, especially to the low-order coal coal cinder of Large stone, because the dehydration of coal cinder inside is not thorough, cause the drying and upgrading deleterious of low-order coal, the calorific value requirement after low-order coal drying and upgrading cannot be met.
Summary of the invention
For prior art Problems existing, the invention provides a kind of polynary drying device of vibratory liquefaction microwave for low-order coal upgrading, the high throughput of low-order coal can be ensured, ensure the dry completeness of low-order coal simultaneously, meet the calorific value requirement after low-order coal drying and upgrading.
To achieve these goals, the present invention adopts following technical scheme: a kind of polynary drying device of vibratory liquefaction microwave for low-order coal upgrading, comprise base, lower box and upper box, described lower box is arranged on base, be connected by support spring between lower box with base, bottom lower box, offer air inlet, and bottom lower box, vibrating motor is installed; Described upper box is packed in above lower box, between lower box and upper box, be provided with sieve plate; Offer charging aperture in described upper box one end, charging aperture connects with sieve plate side, and sieve plate opposite side offers material spilling hole, and the lower box below material spilling hole offers discharging opening; Offer air outlet at described upper box top, and at upper box top, microwave generator is installed.
