Description
Technical field
The utility model relates to drying plant technical field, refers to especially the boiled bed dryer that a kind of heat utilization efficiency is high.
Background technology
Boiled bed dryer is a kind of drying plant for powder material, its general principle is that air is under the suction of high pressure centrifugal ventilator is sent, be heated to the temperature of setting through firing equipment, then directly pass in the oven dry tank that is loaded with powder material, utilize the hot-air of high temperature and high speed to impact powder material, make powder material be boiling shape.Under this state, between hot-air and material, contact widely, strengthen diabatic process, thereby can impel in the short period of time water evaporates, separation in material.Finally, air is being mingled with moisture discharges from drying in tank, reaches the object of drying materials.
But there is the defect of self in this boiled bed dryer in actual use: due under the High Pressure of ventilation blower, the flowing velocity of air is very fast, heat exchange between hot-air and material is abundant not enough, cause still thering is higher temperature from drying the air of discharging in tank, and the air of this part higher temperature generally all directly discharges, so just waste the heat of this part air, reduced the drying efficiency of a whole set of boiled bed dryer.
Utility model content
The utility model proposes a kind of boiled bed dryer, solved in prior art and to have caused compared with high the problem that complete equipment drying efficiency is low because of discharged air temperature.
The technical solution of the utility model is achieved in that boiled bed dryer, comprises
Dry tank, in it, have the powder material that needs oven dry;
Air inlet pipe, for pass into hot-air in described oven dry tank, is provided with air heating apparatus near described oven dry tank place in described air inlet pipe;
Escape pipe, for discharge air in described oven dry tank, is provided with centrifugal fan near described oven dry tank place on described escape pipe;
Heat exchanger, described heat exchanger is communicated between described centrifugal fan and described air heating apparatus, is also provided with air intlet on described heat exchanger.
As one preferred embodiment, described air inlet pipe is communicated in the lower end of described oven dry tank, and described escape pipe is communicated in the upper end of described oven dry tank.
As another preferred embodiment, described air heating apparatus is steam heater.
As the improvement to technique scheme, on the outer surface of described air inlet pipe, described escape pipe, be all coated with thermal insulation layer.
Adopt after technique scheme, the beneficial effects of the utility model are: when this boiled bed dryer uses, under the effect of centrifugal fan, air can enter this circulatory system continuously by the air intlet on heat exchanger, when arriving after air heating apparatus, this part air is heated to higher temperature, then directly pass into and dry in tank by air inlet pipe, in oven dry tank, material is dried, the air (this part air still contains more heat) that temperature decreases is discharged from escape pipe, then enter in heat exchanger, in heat exchanger, this part air carries out heat exchange again, heat wherein enters in this circulatory system again, so just utilize this part heat, avoid it to be directly discharged to and in air, to cause waste, finally improve the heat utilization efficiency of a whole set of boiled bed dryer.
Air inlet pipe is communicated with in the lower end of drying tank, escape pipe is communicated with in the upper end of drying tank, can make hot-air from bottom to top by the material of required oven dry, causes material rolling, boiling, hot-air is fully contacted with material, within the regular hour, can improve the exchange rate of heat.
On the outer surface of air inlet pipe and escape pipe, coated one deck thermal insulation layer can prevent from, between hot-air in air inlet pipe, escape pipe and the external world, heat exchange occurs and causes the waste of heat.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
In figure: 1-is dried tank; 2-air inlet pipe; 3-steam heater; 4-escape pipe; 5-centrifugal fan; 6-heat exchanger; 7-air intlet.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment:
As shown in Figure 1, be a kind of embodiment of the utility model boiled bed dryer, first this dryer comprises a columnar oven dry tank 1, has the powder material that needs oven dry in this oven dry tank 1.
Be provided with one in the lower end of drying tank 1 and pass into its inner air inlet pipe 2, the effect of this root air inlet pipe 2 is exactly the hot-air that passes into continuously higher temperature in tank 1 to drying, so that the powder material of drying in tank 1 is played to drying functions.Be provided with one in the upper end of drying tank 1 and pass into its inner escape pipe 4, the effect of this root escape pipe 4 is exactly that the air of drying in tank 1 is discharged continuously, to take moisture contained in material out of.And the setting of this structure can also make hot-air from bottom to top by the material of required oven dry, cause material rolling, boiling, hot-air is fully contacted with material, within the regular hour, can improve the exchange rate of heat.
In air inlet pipe 2, be provided with air heating apparatus near the place of drying tank 1, the air heating apparatus in this embodiment is preferably steam heater 3, can be by the air heat of lower temperature to higher temperature.On escape pipe 4, be provided with centrifugal fan 5 near drying the place of tank 1, its effect be exactly for this reason the Air Flow in the circulatory system power is provided.
Between centrifugal fan 5 and steam heater 3, be provided with a heat exchanger 6, between three, be connected, and on heat exchanger 6, be also provided with an air intlet 7, supplement continuously for air.The air of discharging from escape pipe 4 is entering into after heat exchanger 6, the heat wherein comprising can be extracted again, and be passed into and dry utilization again in tank 1 along circulation line, the energy recovery wasted before can be returned by this structure, improve the utilization rate of heat.Arrow shown in figure represents the flow direction of air in this system.
In addition, in order to reduce to greatest extent the loss of heat in this dryer, on the outer surface of air inlet pipe 2 and escape pipe 4, also can be coated one deck thermal insulation layer, to prevent, between hot-air and the external world, thermal convection current occurs.
