Description
Technical field
The present invention relates to sludge treatment devices, and in particular to a kind of drying sludge air source heat pump system and its drying sludge
Machine.
Background technique
Currently, for moisture content 80% or so, the moisture content of sludge is higher currently, sludge is after initial centrifugation is handled,
It can not directly be burned, need just be recycled after reducing its moisture content by dehydration and drying.It is dry to sludge
The process of change is completed generally by high-temperature heating or natural desiccation.
Such as the patent that notification number is CN101148309, which disclose a kind of belt-type sludge drier, including carriage body,
It is equipped with upper conveyor belt, middle conveyer belt and lower conveyer belt in the inside of the carriage body, the upper, middle and lower conveyer belt respectively includes
The axis wheel and conveyer belt at both ends are set, and the conveyer belt is mounted on the axis wheel, and the axis wheel is in speed regulating motor
Drive under drive the conveyer belt to operate；It is equipped in the carriage body upper end into bucket, in the lower end side of the carriage body
Equipped with mud mouth, several extractor fans are equipped in the top of the upper conveyor belt.
Extractor fan is made of blower, ventilation shaft, air outlet, air inlet, and the butterfly valve of control air outlet.In carriage body
Side is equipped with the thermal energy air inlet led to inside carriage body, and thermal energy air inlet is connected with the hot-air channel that carriage body side is arranged in
It is logical.The connection of the coke reverberatory furnace of the hot-air channel and peripheral hardware, the hot-air on coke reverberatory furnace top are passed through by thermal energy air inlet
Hot-air channel is delivered to inside carriage body.
When sludge transmits on the conveyor belt, the blower of extractor fan works, and natural wind and hot-air pass through air inlet respectively
Mouthful and the air inlet of thermal energy inlet port, blower by air extract out and by ventilation shaft and be arranged in top air outlet be discharged.In carriage body
Air themperature is generally 50 DEG C -65 DEG C or so.When passage of air is laid with sludge on the conveyor belt, moisture in sludge also with
Air-flow is pulled away.
The shortcomings that patent, is: during dry sludge, a large amount of Hot wet air heating can be discharged, therefore need a direct subsidy
Natural wind and hot-air are filled, makes to maintain operating temperature in carriage body.And by hot air to can make to maintain work in carriage body
When the temperature of temperature, amount of heat is needed, i.e., need to consume a large amount of energy.Cause energy utilization rate low, it is at high cost.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of reduce during drying sludge
Heat energy loss makes full use of the sludge drier of heat source.
To achieve the above object, the present invention provides the following technical scheme that
A kind of sludge drier, including carriage body, are equipped with the transmission belt for being used for transmission sludge in the carriage body, on the carriage body
End and lower end are respectively equipped with inlet port and outlet port, and the carriage body is in sealed set, and the transmission belt is set with respect to feed inlet one end
There is the diversion fan for driving air to form hot-fluid, the transmission belt lower end is equipped with close to diversion fan one end for heating sky
The heating member of gas, the transmission belt lower end are equipped with the evaporator for recycling waste water in Hot wet air heating far from diversion fan one end,
The carriage body inner wall is equipped with back to diversion fan side for guiding hot-fluid to flow to the partition of evaporator, and the evaporator goes out liquid
It is connected with drainpipe on mouthful, the drainage for hot-fluid to be guided into heating member from evaporator is equipped between the evaporator and heating member
Blower.
By using above-mentioned technical proposal, after wet mud enters in carriage body, as transmission belt is back and forth transported in carriage body.This
When diversion fan drive air to form the hot-fluid along transmission belt length direction, sludge expanded by heating distributes the moisture in sludge
It into air, is then taken away by hot-fluid, realizes drying.Hot-fluid is oriented to after flowing through transmission belt by partition, is made with moisture
Hot-fluid flows to evaporator, to reduce hot fluid temperature, so that the moisture in hot-fluid is condensed, is exported by drainpipe, to reduce compartment
Intracorporal total moisture, makes drying sludge.Air-flow after cooled passes through heating member under the action of draining blower, makes its temperature liter
Height becomes hot-fluid again and rises in front of diversion fan, flows under the action of diversion fan along transmission belt length direction, so
Circulation, is completely dried sludge.In above process, carriage body is closed, and air-flow forms a closed heat in carriage body and follows
Ring makes heat as much as possible for drying sludge, rather than is directly discharged in air lead to the loss of heat, improves energy
Source utilization rate.
The further setting of the present invention are as follows: be equipped in the carriage body and flow to water conservancy diversion for being directed through the hot-fluid after heating member
The air curtain plate of blower, the discharge port are located at air curtain backboard to heating member side.
By using above-mentioned technical proposal, hot-fluid is made to flow directly into diversion fan, without passing through discharge port.To use
Material mouth negative pressure forms sealing, reduces the heat from the excessive carriage body that sheds of discharge port, more heats is made to be used for drying sludge.
The further setting of the present invention are as follows: the transmission belt is staggeredly equipped with several along the vertical direction, described in bottom
The discharge end of transmission belt is equipped with stock guide, and the stock guide is tilted down setting towards discharge port one end, the stock guide phase
Discharge port side and air curtain backboard are generally aligned in the same plane discharge port side.
By using above-mentioned technical proposal, thus make the dry sludge finished can accurately discharge hole for discharge, reduce dry
Dry sludge is influenced by hot-fluid and is fallen in the intracorporal probability in compartment.
The further setting of the present invention are as follows: bar shaped slot feed hopper is installed on the feed inlet.
By using above-mentioned technical proposal, sealing is formd using the feed inlet that is deposited in of charging, is reduced from feed inlet
