Description
Technical field
The utility model relates to a kind of rotating cylinder bundled tube drying device, and particularly a kind of tube bank drying device that utilizes flue gas for heat medium can be used for the drying of materials such as bagasse, feed.
Background technology
Flue gas contains a large amount of waste heats capable of using as the waste gas of boiler combustion, and this part waste heat has been wasted at present more.Existing pipe bundle drier is a heat medium with steam, conduction oil usually; How they structurally are made up of pipe bundle heat exchanger, shell, import and export, transmission system and medium heating system, and body is a cylindrical tube, is fixed on the pedestal; Pipe bundle heat exchanger is welded with the end socket of hollow shaft and forms with two tube sheets that heat exchanger tube is housed by two ends; Scraping wings is installed in the tube bank, and power source is through the rotation of actuator drives tube bank rotor, and material is prolonging housing and moving to discharging opening.
Because it is to rotate together with material that pipe bundle heat exchanger is in operation, so the torsion that end socket and tube sheet receive is very big, and is very high to material and welding process requirement.
And be heat medium with flue gas; Its specific heat capacity is little, and the flow of turnover drier adds that much larger than steam, conduction oil the dust in the flue gas is many; Big to the obturator wearing and tearing, therefore can cause the high problem of fault rate in the production process like the structure that adopts above-mentioned drying machine.
The utility model content
The purpose of the utility model is a solution that provides to the deficiency of above-mentioned prior art.
The rotating cylinder bundled tube drying device of the utility model; It is provided with charging aperture 12, the other end by shell 2, an end and is provided with the rotating cylinder 1 of discharging opening 13 and restrains 6 and form, and it is characterized in that: the shell 2 that two ends are provided with smoke-intake pipe 3 and pipe 4 respectively is provided with the rotating cylinder 1 that charging aperture 12, the other end be provided with discharging opening 13 through a sealing ring 5 and an end and is connected; Be connected with rotating cylinder 1 through tube sheet 7 with axial arranged tube bank 6, and communicate with the annular air collecting chamber 8 of shell 2 and 1 setting of rotating cylinder.The quantity of described tube sheet 7 is more than two.
Be provided with some flights 9 around rotating cylinder 1 inwall, be provided with being used to of combining with power source around rotating cylinder 1 outer wall and drive gear ring 10 that rotating cylinder rotates and the ring-like guide rail 15 that combines with guide roller.
The operation principle of the utility model is following:
This revolving drum type tube bundle drying machine is the indirect heating type drying machine, utilizes heat conduction and heat radiation principle, will conduct to the outer material that is dried of tube wall as the heat of the flue gas of the thermal source tube wall through heat-exchanging tube bundle 6; After material gets into charging aperture 12; Through the rotation of rotating cylinder 1,,, and moves flight 9 under driving to discharge end in interbank slip; Discharge through discharging opening 13, material is heated drying in the process of stirring up and down and moving forward.
The flue gas access lane of the utility model is following: flue gas, gets into and is arranged on the tube sheet 7 on the rotating cylinder through annular air collecting chamber 8 from smoke-intake pipe 3, among the logical inlet pipe bundle 6, gets into the air collecting chamber 8 of pipe 4 ends again through the tube sheet of pipe 4 ends, discharges from pipe 4.
Advantage of the utility model and good effect embody in the following areas:
(1) avoids traditional pipe bundle drier heating tube bundle tube sheet, end socket to material, the high problem of welding requirements, reduced cost of manufacture and operation troubles.
(2) avoid in the flue gas dust to the wearing and tearing of end socket, prolonged the service life of spare and accessory parts, improved production stability.
(3) tube bank and material drive by cylindrical shell is whole, reduce the resistance of tube bank, flight and material, reduce transmission power.
(4) pulse is advanced the cigarette mode flue dust in the tube bank is difficult for attached on the tube wall, and be convenient to tube bank and clean: during the rotating cylinder rotation, the opening of tube sheet on drum wall also is in rotation status thereupon; When the tube sheet opening faces toward smoke-intake pipe and pipe; The flue gas flow that gets into tube bank increases, and when the rotation of tube sheet opening faced toward the shell wall, the flue gas flow that gets into tube bank reduced; Flue gas flow in the tube bank forms the air-flow vibrations in the process that increases and reduce; Can make attached to the flue dust on the tube bank inwall to come off, keep the heat transfer efficiency of tube bank wall, also be convenient to tube bank and clean.
