Description
Technical field
The utility model relates to a kind of drying device, is specifically related to a kind of for the Minton dryer for brown coal drying.
Background technology
In China, brown coal reserves are very large, but because the low utilization rate all the time of the large calorific value of its water content is lower, affect its application in industrial and agricultural production, along with the development energy in short supply of society, on market, the use amount of brown coal increases substantially, but is restricted to its extensive use in industrial and agricultural production because its water content is larger.Now commercially brown coal user directly uses, and uses brown coal can cause the problems such as boiler output is inadequate if not the special boiler using brown coal that uses.
Authorized announcement date is on December 24th, 2014, Authorization Notice No. is that the utility model patent of CN204043306U discloses a kind of vacuum brown coal drying device, and specifically disclose connect successively vacuum air-locked device, vacuum to batch can, vacuum drier and condenser system, be provided with vavuum pump above condenser system.Above-mentioned drying device does not carry out classification and vacuumizes, and causes drying efficiency low.
To sum up, existing vacuum brown coal drying device does not carry out classification and vacuumizes, and causes drying efficiency low.
Utility model content
The utility model vacuumizes for the existing vacuum brown coal drying device of solution does not carry out classification, there is the problem that drying efficiency is low, and then provides a kind of Minton dryer for brown coal drying.
The utility model is solve the problems of the technologies described above the technical scheme taked to be:
Minton dryer for brown coal drying of the present utility model comprises coal bunker, vacuum drying tank, vavuum pump, steam-water separator and two vacuum air-locked devices, the lower end of coal bunker is connected with the upper end of vacuum drying tank by a vacuum air-locked device, the lower end of vacuum drying tank is provided with a vacuum air-locked device, vacuum drying tank is double-layer interlayer tank body, the top of vacuum drying tank is provided with high-temperature flue gas entry, the bottom of vacuum drying tank is provided with high-temperature flue gas outlet, vacuum drying tank is provided with five layers along its short transverse and vacuumizes hole, every layer of quantity vacuumizing hole is 2 ~ 4, vacuumize hole to be connected with one end of vavuum pump by pipeline, the other end of vavuum pump is communicated with the top of steam-water separator by pipeline.
The utility model has following beneficial effect:
Minton dryer for brown coal drying of the present utility model adopts extension set to vacuumize, substantially reduce the time vacuumized, thus shorten drying time, substantially increase drying efficiency, and vacuum drying tank is double-layer interlayer tank body, logical high-temperature flue gas in interlayer, the boiling point of water declines under vacuum, by vacuum and heating, the outer water of coal is evaporated, compared with existing vacuum brown coal drying device, drying efficiency improves more than 30%;
The utility model is provided with steam-water separator, and under vacuum condition, the boiling point of water declines, and by vacuum and heating, the outer water of coal is evaporated, releases with vavuum pump, then by steam-water separator, air is emptying, the water of cooling can recycling.
Accompanying drawing explanation
Fig. 1 is the main sectional view of overall structure of the Minton dryer for brown coal drying of the present utility model, and Fig. 2 is the vertical view cutaway drawing of vacuum drying tank 3 in detailed description of the invention one.
Detailed description of the invention
Detailed description of the invention one: as shown in Fig. 1 ~ 2, the Minton dryer for brown coal drying of present embodiment comprises coal bunker 1, vacuum drying tank 3, vavuum pump 4, steam-water separator 5 and two vacuum air-locked devices 2, the lower end of coal bunker 1 is connected with the upper end of vacuum drying tank 3 by a vacuum air-locked device 2, the lower end of vacuum drying tank 3 is provided with a vacuum air-locked device 2, vacuum drying tank 3 is double-layer interlayer tank body, the top of vacuum drying tank 3 is provided with high-temperature flue gas entry 3-1, the bottom of vacuum drying tank 3 is provided with high-temperature flue gas outlet 3-2, vacuum drying tank 3 is provided with five layers along its short transverse and vacuumizes hole, every layer of quantity vacuumizing hole is 2 ~ 4, vacuumize hole to be connected by pipeline one end with vavuum pump 4, the other end of vavuum pump 4 is communicated with by the top of pipeline with steam-water separator 5.
In vacuum drying tank 3 tank, coal seam height accounts for the 80%-90% of whole tank body height, ground floor vacuumizes hole and is arranged on tank base, ground floor vacuumizes hole, the second layer vacuumizes hole, third layer vacuumizes hole, 4th layer vacuumizes hole and layer 5 and vacuumizes hole and set gradually from the bottom to top along vacuum drying tank 3, it is 200mm that ground floor vacuumizes the vertical range that hole and the second layer vacuumize hole, it is 300mm that the second layer vacuumizes the vertical range that hole and third layer vacuumize hole, it is 500mm that third layer vacuumizes the vertical range that Kong Yu tetra-layers vacuumizes hole, 4th layer vacuumizes the vertical range that hole and layer 5 vacuumize hole is 600mm, vacuum drying tank 3 tank body is interlayer manufacture, logical high-temperature flue gas in interlayer, under vacuum condition, the boiling point of water declines, and by vacuum and heating, the outer water of coal is evaporated, releases with vavuum pump, then by steam-water separator 5, air is emptying, the Water Sproading recycling of cooling.
