Abstract
A transversely placed rotary drum reverse air drying furnace is a drying device for drying wet materials in a transversely placed rotary drum by reverse air, and particularly is a drying device capable of improving drying efficiency and reducing energy consumption and electric consumption in the process of processing and producing biomass solidification forming fuels. Smoke gas of the drying furnace enters the transversely placed rotary drum from the tail of the transversely placed rotary drum, the drying furnace can lead the wet materials to sufficiently contact with the reverse smoke gas inside the transversely placed rotary drum, generated steam is exhausted from the front end of the transversely placed rotary drum, and the materials are prevented from directly contacting with excessive steam in advancing process inside the transversely placed rotary drum to be sufficiently dried, thereby the drying furnace reduces heat sources needed by drying and decreases drying electric consumption.
Description
Technical field
The utility model relate to a kind of in horizontal cylinder to dry against the wind the drying plant of wet stock, especially in biomass solid shaping fuel processing process, improve drying efficiency, cut down the consumption of energy and the drying plant of power consumption.
Background technology
At present, traditional horizontal roller dryer is made up of hot-blast stove, flue, charging aperture, discharging opening, horizontal cylinder, rolling stand, cylinder drive gear, cyclone separator, blower fan, chimney.Flue gas is produced through flue by hot-blast stove and is entered by the charging aperture place, and the material in the horizontal cylinder is dried.Flue gas follows steam to walk to discharging opening by the charging aperture place always, by blower fan sucking-off flue gas, steam and a small amount of material, isolate material via cyclone separator, thereby chimney is discharged flue gas and steam is finished the oven dry flow process.Steam is followed material walking always in the whole oven dry flow process, causes the continuous exhaust steam in material outlet place, because material still has a large amount of steam to cause the material can not be fully by the standard of drying at the discharging opening place.This traditional horizontal cylinder is dried design with the wind and is caused drying efficiency very low, even just can make wet stock reach the oven dry standard after secondary or three times, thereby wastes hot fuel and electric power in a large number.
The utility model content
Render a service the high deficiency of low energy consumption in order to overcome existing traditional horizontal cylinder dryer, the utility model provides a kind of horizontal cylinder dryer against the wind, this horizontal cylinder contrary wind dryer can not only reduce energy consumption and the power consumption in the drying course effectively, and can make the drying time of wet stock shorten 1/3rd, improve the purpose that drying efficiency reduces the oven dry cost thereby reach.
The technical scheme that its technical problem that solves the utility model adopts is: hot-blast stove is arranged on the charging aperture place, directly cylinder is heated, and guarantees the operating temperature of drum front end, makes the wet stock of charging aperture that a preliminary oven dry be arranged; Secondly adopt oppositely when flue is provided with and dries flue against the wind, promptly flue gas enters from discharging opening, thereby guarantees that reverse flue gas all dries wet stock; At the charging aperture place blower fan, cyclone separator are set at last, flue gas and steam that temperature reduces are discharged.Because flue gas is reverse oven dry material, moist steam and flue gas are promptly discharged fully at the charging aperture place, thereby make that the wet stock that quilt is dried in the cylinder is dried fully in the posterior segment of cylinder, and at the discharging opening place without any steam.Reach and improve the purpose that drying efficiency reduces oven dry energy consumption power consumption.
The beneficial effects of the utility model are, can in the drying course of wet stock, contact thermal source more completely, avoid too much contacting steam, improve drying efficiency at horizontal cylinder, reduce the fearless loss of energy consumption power consumption, thereby reach the beneficial effect that reduces the oven dry cost.And it is simpler and easy aspect structural design, project construction.
Description of drawings
Fig. 1 is an oven dry schematic diagram of the present utility model.
Fig. 2 is a process chart of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
In the embodiment shown in fig. 1, charging aperture (1), discharging opening (2), exhaust outlet (6) are connected with horizontal cylinder (3) respectively, hot-blast stove (4) flue gas that combustion heat source produced enters from horizontal cylinder (3) afterbody through flue (5), the reverse continuous oven dry of flue gas enters into the interior wet stock of horizontal cylinder (3) from charging aperture (1), and steam that is produced and residue flue gas are attracted to discharge via chimney (8) from exhaust outlet (6) by blower fan (7).Material after the oven dry is discharged via discharging opening (2).
In embodiment illustrated in fig. 2, wet stock is entered in the horizontal cylinder (3) via charging aperture (1) by belt filled machine (9), and hot-blast stove (4) flue gas that combustion heat source produced enters from horizontal cylinder (3) afterbody through flue (5).Horizontal cylinder (3) under the support of drum supporting device (7) by cylinder driver (10) transmission, material in horizontal cylinder (3) by the flight effect under continuous counter-rotating move ahead.The reverse continuous oven dry of flue gas enters into the interior wet stock of horizontal cylinder (3) from charging aperture (1), and steam that is produced and residue flue gas are by being attracted by chimney (8) emptying by blower fan (11) from exhaust outlet (6).Material after the oven dry is discharged via discharging opening (2).
Claims (2)
1. horizontal cylinder drying oven against the wind, it is the reverse a kind of drying unit that wet stock in the horizontal cylinder is dried of hot flue gas that utilizes hot-blast stove to produce, it is characterized in that: flue gas is entered to horizontal cylinder by horizontal cylinder end, and residue flue gas and steam are by the drum front end emptying.
2. a kind of horizontal cylinder according to claim 1 is drying oven against the wind, it is characterized in that, avoid the steam of wet stock and generation too much to contact, the flue gas that is entered by horizontal cylinder afterbody is omnidistance reversely dries wet stock, residue flue gas and steam are by horizontal drum front end emptying, and the material after the oven dry is discharged by horizontal cylinder afterbody and collected.
