Description

Using the drying unit of gas fired-boiler fume afterheat
Technical field
The present invention relates to the drying unit using gas fired-boiler fume afterheat.
Background technology
Gas fired-boiler can produce more high-temperature flue gas, and fume afterheat, if do not utilized effectively, is greatly to waste the energy.
The content of the invention
It is an object of the invention to provide a kind of drying unit, it can be dried using gas fired-boiler fume afterheat to material It is dry.
To achieve the above object, the technical scheme is that designing a kind of drying using gas fired-boiler fume afterheat Device, including roller drying machine, the roller drying machine include the roller as drying tunnel；
The roller includes wet stock input and dry material output end；
The roller is connected with air inlet duct in its dry material input, and air inlet duct is provided with heat exchanger, and heat exchanger is also It is connected with the flue gas exhaust pipe of gas fired-boiler；The gas in gas and air inlet duct in flue gas exhaust pipe is changed by heat exchanger Heat；
The roller its wet stock input be connected with air outlet conduits, air outlet conduits be sequentially provided with cyclone dust collectors, Sack cleaner and the first air-introduced machine, and cyclone dust collectors are positioned between sack cleaner and roller.
It is preferred that, the flue gas exhaust pipe is provided with the second air-introduced machine.
It is preferred that, the roller is equipped with the drive device for driving it to rotate.
The advantages of the present invention are：A kind of drying unit is provided, it can utilize gas fired-boiler fume afterheat Material is dried.
Waste heat flue gas is forcibly introduced into heat exchanger using the second air-introduced machine, the air in air inlet duct is added Heat, hot-air is by roller afterbody（Dry material output end）Into roller, wet stock is by roller head（Wet stock input）Into Rolling, hot-air is inversely contacted with wet stock, by material（Titanium tungsten powder, titanium molybdenum powder）In moisture take away, while for ensure thing Uniformity after material drying, roller is by drive device（Reductor）Drive does not stop rotation, in order to prevent that material produces powder after drying Dirt is, it is necessary to install cyclone dust collectors and sack cleaner additional.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Embodiment
With reference to the accompanying drawings and examples, the embodiment to the present invention is further described.Following examples are only For clearly illustrating technical scheme, and it can not be limited the scope of the invention with this.
The technical scheme that the present invention is embodied is：
As shown in figure 1, a kind of drying unit using gas fired-boiler fume afterheat, including roller drying machine, the roller baking Dry machine includes the roller 1 as drying tunnel；
The roller 1 includes wet stock input and dry material output end；
The roller 1 is connected with air inlet duct 2 in its dry material input, and air inlet duct 2 is provided with heat exchanger 3, heat exchange Device 3 is also connected with the flue gas exhaust pipe 4 of gas fired-boiler；Gas in flue gas exhaust pipe 4 passes through with the gas in air inlet duct 2 Heat exchanger 3 exchanges heat；
The roller 1 is connected with air outlet conduits 5, air outlet conduits 5 in its wet stock input and is sequentially provided with cyclone dust removal Device 6, the air-introduced machine 8 of sack cleaner 7 and first, and cyclone dust collectors 6 are positioned between sack cleaner 7 and roller 1.
The flue gas exhaust pipe 4 is provided with the second air-introduced machine 9.
The roller 1 is equipped with the drive device for driving it to rotate.
Waste heat flue gas is forcibly introduced into heat exchanger 3 using the second air-introduced machine 9, the air in air inlet duct 2 is carried out Heating, hot-air is by the afterbody of roller 1（Dry material output end）Into roller 1, wet stock is by the head of roller 1（Wet stock input） Into rolling, hot-air is inversely contacted with wet stock, by material（Titanium tungsten powder, titanium molybdenum powder）In moisture take away, while for protect The uniformity after drying materials is demonstrate,proved, roller 1 is by drive device（Reductor）Drive does not stop rotation, in order to prevent that material is produced after drying Fecula dirt is, it is necessary to install cyclone dust collectors 6 and sack cleaner 7 additional.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, without departing from the technical principles of the invention, some improvements and modifications can also be made, these improvements and modifications Also it should be regarded as protection scope of the present invention.
