Abstract
The sludge drying cyclonic spouting apparatus includes main tower body, air chamber, driving shaft and drying and stirring paddle. The air chamber is set in the lower part of the main tower body, drying and stirring paddle is set onto the driving shaft, the air chamber has tangent air inlet port and bottom with W-shaped axial section, and the main tower body over the W-shaped bottom of the air chamber with its lower part extending into the air chamber, and has material feeding port and air outlet port in the upper part as well as tangent air exhaust port and air inlet port rotating in the same direction. The present invention has the high tightness, high drying efficiency, low power consumption, sterilization effect, no jamming and simple apparatus.
Description
Technical field
The present invention relates to a kind of drying installation, relate in particular to a kind of swirl spouting device that is used to handle the drying sludge of mud.
Background technology
At present, drying sludge adopts tumble dryer or fluid bed dryer etc. mostly.Mainly there is following technical problem in tumble dryer: the air that 1, easily bleeds, increased the oxygen level of drying medium, and be similar to and volatility is higher than the drying of the mud of brown coal for combustionproperty, then increased the possibility that detonation takes place.2, easily sticking wall, the viscosity of mud is stronger, very easily sticks on the drum wall, thereby influences drying efficiency, even equipment can not normally be moved.3, device is huge, heat lost by radiation big, dry heat efficient is low.The stopping property of fluid bed dryer is better than tumble dryer, but it generally be used for the less mud of viscosity drying (as city sewage and sludge), drying (as biochemical sludge) for the bigger mud of viscosity often adopts first granulation after drying technology, equipment manufacturing cost height, system complex.And its drying rate is little, and inlet air temperature can not be too high, and dry heat efficient is also lower.
Summary of the invention
The invention provides a kind of be used for drying sludge, mud is difficult for the swirl spouting device of the drying sludge of sticking wall, drying efficiency height, compact construction.
The present invention adopts following technical scheme:
A kind of swirl spouting device of drying sludge, form by main tower, air compartment, transmission shaft and dry stirring blade, air compartment is located at the bottom of main tower, dry stirring blade is located on the transmission shaft, is provided with charging opening and air outlet on main tower, is provided with inlet mouth on air compartment, the axial section of air compartment bottom surface is " W " shape, inlet mouth is the tangential admission mouth, and main tower is positioned at top at the bottom of air compartment " W " shape and air compartment is stretched in the bottom of main tower, and venting port is and the homodromal tangent exhaust outlet of inlet mouth.
Compared with prior art, the present invention has following advantage:
1, device good leak tightness can make drying carry out under the condition of hypoxemia (oxygen level can be lower than 2%), has almost eliminated the possibility of mud detonation in drying process.
2, thermal insulation of dry whipping appts drive disk assembly and water cooling design, applicable to higher inlet air temperature (inlet air temperature can reach 750 ℃), drying efficiency is higher, and energy consumption for drying is lower.And the effect that comparatively high temps can make drying medium and mud produce sterilization.
3, be the air compartment that inverted cone shape has the tangential admission mouth, make mud in drying process, be fierce swirl spouting state, the drying rate height, and for viscosity greatly and the mud of high moisture content can not stop up tower body yet, make drying to carry out continuously and stably.
4, be difficult for sticking wall.The air-flow of high speed rotating has the intensive souring to the tower body wall, reduced the possibility of the sticking wall of mud, and stirring blade is triangular shaped, no matter just changeing or when reversing, drying medium and mud all are subjected to reactive force upwards, can under low speed, turn round, reduce making mud get rid of centrifugal force to inwall.Stirring blade top cut edge of a knife shape, the feasible mud that is bonded on a small quantity on the tower wall produces shear action and comes off.
5, air compartment is designed at the bottom of " W " shape, can make dry operation continuously and stably under the low-resistance condition.Enclose guide functions outward, reduced gas-flow resistance; Inner ring has changed the sectional area of main tower different heights, makes the intravital wind speed of king-tower downward more high more, has avoided not dried big wet mud to sink to the bottom and blocks air intake annular space mouth.
6, device is simple efficient, and area is little, and installation and maintenance are convenient.
