Description
Technical field
The present invention relates to mud and sludge reduction processing technology field, refers in particular to a kind of low energy consumption mud or sludge is dry
Change or cured method.
Background technique
Technique of soft soil foundation treatment is the widely applied skill for mud/sludge drying or in terms of solidify in China in recent years
Art.Vacuum preloading is that plastic draining board is vertically plugged in mud/sludge, and top hand connector is by drain bar and vacuum-pumping tube
Net is connected, and woven cloth and geotextiles is laid on mud face, again with the sealing of air-locked sealing film, makes an enclosed area, so
Afterwards by the gas and water fluid in pumped vacuum systems pump drainage enclosed area, keep the inside and outside generation certain pressure of sealing film poor, this pressure difference is
To be applied to mud/Sludge Surface external load.Mud/sludge is with the increase of pressure difference and the extension of squeeze time, hole
In water be constantly discharged and consolidated, thus make mud intensity increase, compressibility reduce.
Vacuum preloading can generally reach the prefabricating load of 70-80KPa, have it is easy to operate, it is excellent without secondary pollution etc.
Point has certain desiccation or solidification effect.But its disadvantage is it is also obvious that existing vacuum preloading is all arranged using upper row's formula
Water, to overcome during draining water from gravity and filter cloth, water draining pass to the drag effect of water, and later period desiccation or
Solidification reaches a certain level rear effect and tends to stop, and energy consumption is high, and 70% or more mud containing rate, the sludge of mud are not achieved toward contact
58% or more mud containing rate, sludge volume reduces compared with nature and 60%, sludge volume is not achieved subtracts compared with nature
50% is not achieved less.
Summary of the invention
In view of this, in view of the deficiencies of the prior art, the present invention aims to provide a kind of low energy consumption mud
Or sludge drying or cured method, it can effectively solve existing mud/sludge drying or curing method there are energy consumptions and is high, dry
The problem of change or solidification effect.
To achieve the above object, the present invention is using following technical solution:
A kind of low energy consumption mud or sludge drying or cured method, include following steps:

Device；Drainage pipe connect to form drainage channel with vertical drainage device lower part；Extend desiccation in the port of the drainage pipe
Or outside solidifying pool；
(3) mud or sludge are discharged into: it is discharged into mud or sludge in the desiccation or solidifying pool that step (2) lays drainage system,
Water in mud or sludge enters drainage pipe by vertical drainage device, and the water level of vertical drainage device is higher than drainage pipe
When port, water is directly flowed out from port, and when the water level of vertical drainage device is lower than the port of drainage pipe, port and draining pump connect
It connects, the water in drainage pipe is excluded by power, until anhydrous discharge in drainage pipe；
(4) accelerate desiccation or solidification equipment: after the completion of step (3) is discharged into mud or sludge, to accelerate in mud or sludge
The wirerope or vertical bar of fixed vertical drainage arrangement are removed in water discharge, and sealing film sealing is laid on mud face；Drainage pipe port
It is controlled to a vacuum pump, by vacuumizing draining to drainage system, until the surface of mud or sludge when being decreased obviously variation without stopping
It only vacuumizes, removal sealing film；
(5) improve treatment effect measure: after the completion of step (3) or step (4), drainage pipe port is blown into drying with air blower
Air or 20-100 DEG C of heating air accelerate dry air or heat flowing of the air in vertical drainage device, and take out of
Moisture keeps the mud or sludge fast dewatering close to vertical drainage device dry and cracked, increases and air-dry surface area, until mud or sludge
Mud containing rate reach predetermined value.
Preferably, in the step (5) mud containing rate of mud up to 70% or more；The mud containing rate of sludge is up to 58% or more.
Preferably, sludge volume reduces 60% compared with nature in the step (5)；Sludge volume and nature
Compared to reduction 50%.
Preferably, the pumpdown time is 20-100 days in the step (4), vacuum degree 70-90kPa.
