Description
Technical field
The present invention relates to sludge treatment device, and in particular to a kind of drying sludge air source heat pump system and its drying sludge
Machine.
Background technology
At present, at present, after initial centrifugation process, 80% or so, the moisture content of sludge is higher for its moisture content for sludge,
Cannot directly be burned, be needed through dehydration and drying so as to which moisture content can be just recycled after reducing.Dry to sludge
The process of change is completed generally by high-temperature heating or natural mummification.
If notification number is the patent of CN101148309, a kind of belt-type sludge drier is which disclosed, including envelope,
Upper conveyor belt is provided with the inside of the envelope, middle conveyer belt and lower conveyer belt, described upper, middle and lower conveyer belt include respectively
The axle wheel and conveyer belt at two ends is arranged on, on described axle wheel, described axle wheel is in buncher for described conveyer belt
Drive under drive described conveyer belt operating；It is provided with into bucket in described envelope upper end, in the lower end side of the envelope
Mud mouth is provided with, above the upper conveyor belt, is provided with several extractor fans.
Extractor fan is by blower fan, ventilation shaft, air outlet, air inlet, and the butterfly valve composition of control air outlet.In envelope
Side is provided with the heat energy air inlet led to inside envelope, and heat energy air inlet is connected with the hot-air channel for being arranged on envelope side
Logical.The hot-air channel is connected with the coke reverberatory furnace of peripheral hardware, and the hot-air on coke reverberatory furnace top is passed through by heat energy air inlet
Hot-air channel is delivered to inside envelope.
When sludge is transmitted on the conveyor belt, the blower fan work of extractor fan, natural wind and hot-air pass through air intake respectively
Mouthful and heat energy inlet port air inlet, blower fan by air extract out and by ventilation shaft and be arranged on top air outlet discharge.In envelope
Generally 50 DEG C -65 DEG C or so of air themperature.When passage of air laying sludge on the conveyor belt, the moisture in sludge also with
Air-flow is pulled away.
The shortcoming of the patent is：During sludge is dried, substantial amounts of Hot wet air heating can be discharged, therefore need a direct subsidy
Natural wind and hot-air is filled, makes in envelope, to maintain operating temperature.And by hot air to can make to maintain work in envelope
During the temperature of temperature, amount of heat is needed, that is, need to consume the substantial amounts of energy.Cause energy utilization rate low, high cost.
Content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of reduce during drying sludge
Heat energy loss, makes full use of the sludge drier of thermal source.
For achieving the above object, the invention provides following technical scheme：
A kind of sludge drier, including envelope, is provided with the envelope for transmitting the transmission belt of sludge, the envelope upper end and
Lower end is respectively equipped with charging aperture and discharging opening, and the envelope is arranged in sealing, and the transmission belt is provided with use with respect to charging aperture one end
In the diversion fan for driving air to form hot-fluid, the transmission belt lower end is provided with for heating air near diversion fan one end
Heating member, the transmission belt lower end are provided with for reclaiming the vaporizer of waste water in Hot wet air heating away from diversion fan one end, described
Envelope inwall is provided with the dividing plate for guiding hot-fluid to flow to vaporizer back to diversion fan side, on the liquid outlet of the vaporizer
Drain pipe is connected with, is provided between the vaporizer and heating member for hot-fluid to be guided into from vaporizer the drain wind of heating member
Machine.
By adopting above-mentioned technical proposal, after wet mud entrance envelope is interior, as transmission belt is back and forth transported in envelope.This
When diversion fan drive air to form hot-fluid along transmission belt length direction, sludge expanded by heating distributes the moisture in sludge
To in air, then taken away by hot-fluid, realize drying.Hot-fluid is oriented to by dividing plate after transmission belt is flow through, and is made with moisture
Hot-fluid flows to vaporizer, so as to reduce hot fluid temperature, makes the moisture in hot-fluid be condensed, is derived by drain pipe, to reduce railway carriage or compartment
Internal total moisture, makes drying sludge.Air-flow after cooled is in the presence of drain blower fan through heating member so as to temperature liter
Height, is changed into hot-fluid again and rises in front of diversion fan, flows along transmission belt length direction, so in the presence of diversion fan
Circulation, makes sludge completely dried.In above process, envelope is closed, and air-flow defines the heat of a closing in envelope and follows
Ring, makes heat as much as possible for drying sludge, rather than the loss for being directly discharged in air cause heat, improves energy
Source utilization rate.
The further setting of the present invention is：Be provided with the envelope water conservancy diversion is flowed to for being directed through the hot-fluid after heating member
The air curtain plate of blower fan, the discharging opening are located at air curtain backboard to heating member side.
By adopting above-mentioned technical proposal, hot-fluid is made to flow directly into diversion fan, without through discharging opening.So as to use
Material mouth negative pressure forms sealing, reduces the heat of envelope of shedding that overflows from discharging opening, makes more heats be used for drying sludge.
The further setting of the present invention is：The transmission belt is vertically staggeredly equipped with several, described in bottom
The discharge end of transmission belt is provided with stock guide, and the stock guide is tilted down setting towards discharging opening one end, the stock guide phase
