Below, oily sludge is innoxious being used for of being provided the embodiment of the present invention and the process system of disposal of resources
Operation principle makees corresponding description, and in the course of the work, moisture, oils and the high-temperature flue gas of oily sludge are respectively accordingly
Operated in system, it is described in detail below：
1st, moisture drying system
Oily sludge is sent into moisture drying kiln 100 by the first belt conveyor 101, with the high temperature from the first combustion chamber 105
Flue gas mixes in kiln porch.The heat in moisture absorption high-temperature flue gas in oily sludge, progressively evaporates, and reaches required and contains
After water rate, expel from kiln, oils evaporation kiln 200 is sent into by the second belt conveyor 201.
During moisture is evaporated, temperature gradually reduces high-temperature flue gas, finally with the steam that is evaporated and containing greasy dirt
The oil gas of mud loss discharges moisture drying kiln 100 together, into the first cyclone cylinder 102.Come out with flue gas, steam and oil gas
Also have dust, most dust settles down in the first cyclone cylinder 102, is discharged into the second belt conveyor 201, is sent into oil
Class evaporates kiln 200.A small amount of dust leaves the first cyclone cylinder 102 with flue gas, steam and oil gas, into water vapor condenser 103.
Cold wind is blasted water vapor condenser 103 by condensation fan 106.Cold wind and flue gas, steam from the first cyclone cylinder 102
Indirect heat exchange is carried out in water vapor condenser 103 with oil gas, most steam and a small amount of oil gas are condensed.It is uncooled
Steam is extracted out with flue gas by the first blower fan 104, is divided into two-way, is sent to oil-gas condenser 203 all the way, is cooled down from the second rotation
The oil gas that air duct 202 comes out；Another way is sent to steam heat exchanger 307, the circulating flue gas as moisture drying system.Under condensation
The water and oil come is delivered to specified storage tank by pumping equipment, carries out water-oil separating, the oil separated is used as fuel, separated
Water be used for cool down.A small amount of dust also settles down in water vapor condenser 103, Sui Shui and oily eductor condenser together.
Be sent to steam heat exchanger 307 circulating flue gas be heated to the temperature specified after, into the first combustion chamber 105.
The first combustion chamber 105 is sprayed into after oil atomization, with the high temperature air mixed combustion heat release from air preheater 304, cigarette will be circulated
Gas is heated to sufficiently high temperature.High temperature circulation flue gas is in the presence of negative pressure, and into moisture drying kiln 100, evaporation contains greasy dirt
Moisture in mud.
2nd, oils vapo(u)rization system
The oily sludge of oils evaporation kiln 200 is sent into by the second belt conveyor 201, with coming from the second combustion chamber in kiln
205 high-temperature flue gas contact, heat absorption heating, oils evaporation.After the temperature of oily sludge is increased to a certain stage, oils is whole
Cracking and evaporation, are left clean soil.The clean soil discharge oils evaporation kiln 200 of anhydrous oil-free, is cooled down quenched into the pure land
Facility 402, backfilled after cooling down and be quenched.
During oils is evaporated, temperature gradually reduces high-temperature flue gas, is finally discharged together with the oil gas being evaporated
Oils evaporates kiln 200, into the second cyclone cylinder 202.There are dust, most dust with what flue gas and oil gas came out
Settled down in the second cyclone cylinder 202, return to oils evaporation kiln 200.A small amount of dust leaves second with flue gas and oil gas
Cyclone cylinder 202, into oil-gas condenser 203.
The water condensed out from water vapor condenser 103 sprays into oil-gas condenser 203 after atomization, from water vapor condenser 103
Part cold flue gas out is sent into oil-gas condenser 203 by the first blower fan 104, common to cool down the cigarette from the second cyclone cylinder 202
Gas and oil gas, most oil gas are condensed.Uncooled oil gas is extracted out with flue gas by the second blower fan 204, is divided into
Two-way, sack cleaner 301 is sent to all the way, carry out purification and burn disposal；Another way is sent to the second combustion chamber 205, as
The circulating flue gas of oils vapo(u)rization system.A small amount of dust also settles down in oil-gas condenser 203, is condensed with oil discharge
Device.
The second combustion chamber 205 is sprayed into after oil atomization, and the high temperature air mixed combustion heat release from air preheater 304,
Circulating flue gas is heated to sufficiently high temperature.Oil gas in circulating flue gas is also in the combustion heat release of the second combustion chamber 205.High temperature follows
Ring flue gas evaporates kiln 200 in the presence of negative pressure, into oils, evaporates the oils in oily sludge.
3rd, flue gas is burnt and cleaning system
The partial fume and oil gas come out from oil-gas condenser 203 is sent into sack cleaner 301 by the second blower fan 204, passes through
Basic carbonate hydrogen sodium sprays into the effect of sack cleaner 301, flue gas and oil gas in cloth bag and medicament after superfine powder machine 306 crushes
Under, dust separation.Flue gas and oil gas are extracted out by the 3rd blower fan 302 after purification, are sent into oil gas heat exchanger 303, are heated.Flue gas
After certain temperature is heated to oil gas, burning chamber 300 is sent into.
After oil atomization spray into burning chamber 300, with from oil gas heat exchanger 303 come out oil gas, from air preheater 304
High temperature air mixed combustion, by flue gas to more than 800 DEG C, wipe out the harmful constituent in flue gas.Through burning purification
High-temperature flue gas afterwards passes through oil gas heat exchanger 303, air preheater 304 and steam heat exchanger 307 successively, respectively heat oil gas,
Air and steam, the heat in abundant recovered flue gas.Flue gas is after heat exchange, into flue gas monitoring drain facility 401, index
Air is discharged into after qualified, if not up to standard can carry out subsequent treatment.
Combustion air is blasted air preheater 304 by combustion fan 305.After combustion air is heated to certain temperature, point
The first combustion chamber 105, the second combustion chamber 205 and burning chamber 300 are not sent into, participates in burning, heat flue gas.
What the embodiment of the present invention was provided be used for, and oily sludge is innoxious and the process system of disposal of resources, by direct
The mode of contact heat-exchanging, the heat needed for drying and being pyrolyzed directly is provided to oily sludge, realize innoxious, the money of oily sludge
Sourceization is disposed.Because the heat exchange efficiency of direct contact heat transfer is high, substantial amounts of heat can be provided to oily sludge in a short time, because
This treating capacity is substantially improved, up to more than 50 ton hours.The system has very strong adaptability, is applicable to different oil contents
With the sludge of moisture content.
In addition, the system makes full use of contained combustible component in oily sludge to provide heat, equipment self-operating is maintained.It is right
It is high in oil content and sludge that moisture content is low, the heat that its combustible component (oil) provides have exceeded the need of maintenance system self-operating
Will, the system can reclaim the fuel oil having more by way of condensation, use for different purpose；For oil content is low and dirt that moisture content is high
Mud, for the shortage of heat that its combustible component (oil) provides to maintain the needs of system self-operating, the system can be by supplementing fuel
Mode extra thermal source is provided.
Above-mentioned embodiment is only the preferred embodiment of the present invention, it is impossible to the scope of protection of the invention is limited with this,
The change and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed scope.
