Abstract
The invention discloses a tail gas circulating pneumatic drier. The drier comprises a gas inlet, a first cyclone separator, a second cyclone separator and an exhaust port, wherein an air inlet is connected with an inlet of the first cyclone separator through a first drying pipe, the air inlet is connected with an inlet of the second cyclone separator through a second drying pipe, an outlet of the second cyclone separator and the first drying pipe are connected in a circulation mode through a circulating pipe, an outlet of the first cyclone separator is communicated with the exhaust port through an exhaust pipe, and a feeding port is arranged on the first drying pipe. By the aid of the above mode, second-stage tail gas can be circulated to the first stage to be mixed with heat, is reused and is dried, the energy is saved by 30%, the automatic degree is high, the drying effect is good and the drier can be applied widely.
Description
Technical field
The present invention relates to the drying machine field, particularly relate to a kind of circulation of tail gas pneumatic drier.
Background technology
Pneumatic drier is to utilize swiftly flowing thermal current that wet starch is suspended in wherein, carries out drying in the air current flow process.The characteristics such as have the heat transfer coefficient height, heat transfer area is large, and drying time is short.Pneumatic conveying drying claims that also " wink-dry " is that dilute phase is carried application aspect dry in the fluidization of solid.This method is that heat medium is directly contacted with solid particle to be dried, and solid particle to be dried is suspended in the fluid, thereby the two-phase contact area is large, has strengthened heat and mass transfer process, is widely used in the drying unit operation of bulk material.
Traditional pneumatic drier all exists energy consumption large, and the problems such as production cost height advocating energy-conservation social environment, can not be widely used.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of circulation of tail gas pneumatic drier, can be energy-conservation 30%, and dry tenacity is large, and cost is low.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of circulation of tail gas pneumatic drier is provided, comprise: air inlet, the first cyclone separator, the second cyclone separator, exhaust outlet, air inlet is connected with described the first cyclone inlet by the first drying tube, air inlet is connected with described the second cyclone inlet by the second drying tube, circulate by a circulation pipe between the outlet of described the second cyclone separator and the first drying tube and be connected, the outlet of described the first cyclone separator is communicated with exhaust outlet by blast pipe, and described the first drying tube is provided with charging aperture.
In a preferred embodiment of the present invention, be provided with blower fan between described charging aperture and the first cyclone separator.
In a preferred embodiment of the present invention, be connected with dust arrester on the described exhaust outlet, be connected with the condensate water outlet with described dust arrester.
In a preferred embodiment of the present invention, described the second cyclone separator is provided with airlock.
In a preferred embodiment of the present invention, be connected with heat exchanger on the described air inlet.
The invention has the beneficial effects as follows: circulation of tail gas pneumatic drier of the present invention to the first order and mix hot gas and again utilize and carry out drying, energy-conservation reaches 30% with the circulation of tail gas of the second level, and automaticity is high, and drying effect is good, is suitable for extensive use.

Circulation pipe 7 mixes the drying of carrying out the first cyclone separator 2 with used high temperature low humidity tail gas in the second cyclone separator 3 with from the hot gas that air inlet replenishes, high humidity low temperature exhaust gas after the use is by outside the blast pipe 8 eliminating machines, and dried semi-finished product are undertaken in the second cyclone separator 3 dry by fresh hot-air.
Described the first drying tube 5 is provided with charging aperture 9, is provided with blower fan 10 between described charging aperture 9 and the first cyclone separator 2.
Be connected with dust arrester 12 on the described exhaust outlet 4, be connected with the condensate water outlet with described dust arrester 12.
Described the second cyclone separator 3 is provided with airlock 11.Airlock 11 can effectively be avoided the loss of hot blast energy.
Be connected with heat exchanger on the described air inlet 1.Provide hot blast by heat exchanger for whole dry run.
Circulation of tail gas pneumatic drier of the present invention to the first order and mix hot gas and again utilize and carry out drying, energy-conservation reaches 30% with the circulation of tail gas of the second level, and automaticity is high, and drying effect is good, is suitable for extensive use.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
