Description
Technical field
The invention belongs to field of chemical equipment, being specifically related to a kind of when carrying out drying to material to be dried, can collecting to thermal current the back-heating type pneumatic drier be again used.
Background technology
In Chemical Manufacture, often can use pneumatic conveyer dryer and drying is carried out to bulk granular material.Bulk granular material to be dried operationally, is disperseed by velocity heated gas by pneumatic conveyer dryer, and because thermal current is relative to the flow at high speed of material, and the alternate contact area of gas-solid is very large, and volumetric heat transfer coefficient is quite large, and bulk granular material is able to drying.
But existing pneumatic conveyer dryer is after in use, thermal current carries out drying to material, the thermal current after use still containing a large amount of heats, but but lacks and processes accordingly it, causes the waste of the thermal current utilizing energy sources for heating to obtain.If can collection be carried out to used thermal current and again utilize, the energy needed for heat hot air-flow can be reduced, for enterprise greatly reduces cost.
Therefore, develop a kind of can to collect the device be again used be those skilled in the art institute urgent need to solve the problem to the thermal current after using.
Summary of the invention
For solving the problem, the invention discloses a kind of when carrying out drying to material to be dried, can collect to thermal current the back-heating type pneumatic drier be again used.
In order to achieve the above object, the invention provides following technical scheme:
A kind of back-heating type pneumatic drier, comprises thermal current conduit, material bin, grit storehouse and thermal current recovery channel; One end of thermal current conduit is connected with cyclone separator, and the other end is connected to the top of material bin; The side of material bin has door, and the bottom of material bin is connected with the top in grit storehouse; The top side wall in grit storehouse connects thermal current recovery channel by thermal current refluxing opening, and bottom also has clean-up port; Thermal current recovery channel comprises recovery channel and lower recovery channel; Lower recovery channel tilts to be connected with thermal current refluxing opening; The bottom of upper recovery channel is provided with screen pack, and is connected with lower recovery channel.
The invention provides a kind of back-heating type pneumatic drier, be made up of thermal current conduit, material bin, grit storehouse and air flow recovery pipeline.
One end of thermal current conduit in the present invention connects cyclone separator, the other end is connected to the top of material bin, air-flow after heating enters cyclone separator, in cyclone separator guide vane effect under, produce strongly rotate, enter Whirlwind barrel downwards along cylindrical shell spirality, the grit that density is larger is thrown toward wall under the action of the centrifugal, under gravity, fall to flowing out the bottom of tornadotron dust-exhausting port to cyclone separator along cylindrical shell, and flow out; Clean thermal current through dedusting then enters material bin by thermal current conduit.
The side of material bin has door, is convenient to material to be dried to put into material bin, by thermal current at a high speed by material dispersion to be dried, while carrying out drying to it, clears up the grit that its surface exists; The grit dropped and thermal current enter in grit storehouse together, the thermal current that temperature is higher enters thermal current recovery channel by thermal current refluxing opening, and by screen pack, the grit that may exist in the thermal current of rising is removed, obtain used clean thermal current, conveniently carry out recycling.
As preferably, the sidewall of material bin is also evenly provided with cleaning spray orifice, and is provided with cleaning shower nozzle by cleaning spray orifice; Cleaning nozzle connecting water receiving pipe.
In the present invention, the sidewall of material bin is provided with cleaning spray orifice, and for installing cleaning shower nozzle, cleaning nozzle connecting water receiving pipe carries out hydro-peening to material to be dried in material bin, makes its dried surface keep clean.
As preferably, the bottom edge of upper recovery channel is evenly provided with La Erka; The tip edge of lower recovery channel is provided with a circle groove; La Erka and fit depressions.
In the present invention, thermal current recovery channel is made up of upper recovery channel and lower recovery channel, and the bottom edge of upper recovery channel is evenly provided with La Erka, forms female joint; The top of lower recovery channel is provided with a circle groove, forms male joint; Both are common forms Earrings type snap joint, utilizes self-lock mechanism to combine closely.
As preferably, lower recovery channel and thermal current refluxing opening acutangulate are 15-60 °.
In the present invention, lower recovery channel and the acute angle alleged by thermal current refluxing opening are designed to 15-60 °; If angle too small, then descend the horizontal sectional area of recovery channel too small, affect the flow velocity of thermal current; If angle is excessive, then descend recovery channel close to level, grit is easily brought in lower recovery channel by thermal current, may cause blocking; Therefore be 15-60 ° by angle design, the flow velocity of thermal current in lower recovery channel can either be kept, can prevent grit from piling up in lower recovery channel simultaneously.
Compared with prior art, beneficial effect is in the present invention: (1) structure is simple, be easy to demolition and maintenance; (2) can reclaim thermal current while cleaning-drying is carried out to material; (3) for enterprise has saved production cost.
