Specific embodiment
A kind of whirlwind expansion drying system of sludge, as shown in figure 1, it includes drying machine 10, in the side wall of drying machine 10
Portion is provided with wet mud charging aperture 11, and the bottom of drying machine 10 is provided with hot-air inlets 12 and agitator 13, drying machine 10 it is upper
Portion is provided with gas material outlet 14, and gas material outlet 14 and is provided with pressure-reducing valve, it is characterised in that：The gas material outlet 14 of drying machine 10 is connected
The entrance 41 of cyclone separator 40, is provided with and the heat sky in the pipeline on the pipeline at the air outlet 42 of cyclone separator 40
Gas and water vapour carries out the grid heat exchanger 20 of heat exchange, and cold water is flowed into from the import 21 of grid heat exchanger 20, is produced through heat exchange
Hot water is discharged from the outlet 22 of grid heat exchanger 20.When using, during wet mud put into drying machine 10, wet mud and hot-air
The thermal current that import 12 enters is sufficiently mixed, and is depressurized after reaching certain pressure, and now wet mud is at high speed swirling eddy and bottom
Under the collective effect of portion's agitator, wet mud is centrifuged, is sheared, being collided, rubbing action and make moisture therein drying set
Rapid boiling vaporization in standby, simultaneously also by micronized, because gas-particle two-phase makees rotational flow, solid phase inertia is more than gas phase to sludge,
The alternate relative velocity of solid and gas two is larger, enhances two alternate mass-and heat-transfers, improves drying efficiency, sludge after drying
Taken out of from the gas material outlet 14 on the top of drying machine 10 by air-flow, then can obtain drying after the separation and collection of cyclone separator 40
Sludge powder.At the same time, the hot-air and the temperature of steam for being flowed out in the pipeline at the air outlet 42 of cyclone separator 40
Degree is higher, therefore grid heat exchanger 20 is arranged on pipeline at the air outlet 42 of cyclone separator 40, so can be effectively
These thermals source are recycled, so as to effectively increase the thermal source utilization rate of drying system.
Specifically, as shown in Figure 1-2, described drying system includes feeding screw 30, the discharging of feeding screw 30
Mouth 31 is connected with wet mud charging aperture 11；The feeding screw 30 is that the inner and outer pipe 32,33 overlapped by tube core is arranged arrangement
Constitute, the rotating shaft 34 of the conveying material of feeding screw 30 is arranged in the tube chamber of inner tube 33, the interlayer between inner and outer pipe 32,33
Gap constitutes heating paths 35, and the import and export 21,22 of grid heat exchanger 20 is respectively communicated with the cooling water outlet 35b of heating paths 35
With hot water inlet 35a.That is, the heat in the pipeline at the air outlet 42 of grid heat exchanger 20 and cyclone separator 40 is empty
The hot water circuit that gas and water vapour carries out heat exchange generation is passed through the heating paths 35 of feeding screw 30, so can effectively by
These UTILIZATION OF VESIDUAL HEAT INs get up to carry out the preheating of wet mud, and then improve the heat utilization rate of drying system, reduce the dry of wet mud
Dry cost.
Further, as shown in figure 1, described drying system also includes wet scrubber 50, wet scrubber 50 enters
Gas port 51, gas outlet 52 connect the air outlet 42 of cyclone separator 40 and the air-vent of air-introduced machine 60 respectively.Handed over through heat in pipeline
Change generation dust-laden, containing water flow through wet scrubber 50 dust removal process, so can effectively by granule dust therein
Get off with moisture collection, and then avoid the gas finally from the outer row in gas outlet 52 from polluting air ambient.
As further scheme, as shown in figure 1, two hot-airs have been arranged symmetrically in the bottom sidewall of drying machine 10 entering
Mouthfuls 12,12a, hot-air enters in drying machine from two hot-air inlets 12,12a tangent lines, two hot-air inlets 12,12a
Tangent line airintake direction is parallel and conversely, so hot-air enters the ascending air that can be produced in drying machine 10 and circled round at a high speed, wet dirt
Mud, can farthest by hot air, also beneficial to flash distillation in wet mud after depressurizing under the stirring action of agitator 13
The moisture of gasification takes drying machine 10 out of.Specifically, be provided with heater 70 at hot-air inlets 12, the heater 70 and pressure fan
80 connections, to provide hot-air for drying machine 10.
Preferably, as shown in figure 1, the inside of the drying machine 10 is provided with feed separation baffle plate 15, the feed separation gear
Plate 15 is located at its lower edge of the oral pore of gas material outlet 14, and sludge so after drying is by air-flow from drying machine 10
The gas material outlet in portion 14 is taken out of, obtains drying sludge powder after trapping, and particle too big or humidity sludge material higher then by
Skimming baffle 15 intercepts and continues back at and be further dried in drying machine 10, until being taken out of by air-flow.
Further, described pressure-reducing valve is anti-cavitation high pressure valve, because flashing operation easily produces cavitation to damage on valve
It is bad, so anti-cavitation high pressure valve should be selected, it is characterized in that it can repeatedly throttle and shares pressure difference, or resistance to cavitation can also be selected
Wash away the pressure-reducing valve of material.
