Abstract
The present invention relates to technical field of sludge treatment, particularly relate to a kind of microwave method and process mud.Comprise the following steps: 1) to the mechanical sludge dewatering after liquefaction, with sludge pump, the mud after liquefaction is squeezed into settling apparatus/dehydration equipment at 200 300 DEG C, the mud after being dehydrated；2) high temperature mud step 1 obtained is transported to microwave-heating reactor, in microwave-heating reactor, with the velocity of vibration of 5 millis m/min, high temperature mud is shaken, simultaneously, the microwave-heating reactor microwave irradiation power with 300 watts and the microwave frequency of 2000MHz, the high temperature mud of vibrations is carried out microwave-heating, and pyrolysis time is 40 minutes.3) mud after pyrolysis is transported in cooler.Invention, initially with heat treatment, uses microwave treatment the most again, it is possible to significantly reduce moisture percentage in sewage sludge, also has the advantage that Treatment of Sludge energy consumption is low, thus effectively facilitate recycling sludge.
Description
Technical field
The present invention relates to technical field of sludge treatment, particularly relate to a kind of microwave method and process mud.
Background technology
Owing to, in the mud that sewage treatment plant produces, usually containing substantial amounts of moisture, thus increasing mud subsequent treatment
Cost.Therefore, before carrying out mud subsequent treatment, it is required to first mud be carried out dehydrating operations, and then it is aqueous to reduce mud
Rate.
At present, the mud still moisture content after dehydration is higher, and usual moisture content is between 70%-80%, therefore,
On the one hand, it is unfavorable for mud is carried out subsequent treatment；On the other hand, increased the weight of mud is carried out the cost of subsequent treatment.It addition,
Existing drying method for sludge, generally has the deficiency that energy consumption is high, thus increases drying sludge processing cost.
Summary of the invention
For defect or deficiency present in prior art, the technical problem to be solved is: provide a kind of micro-
Ripple method processes mud, can effectively reduce moisture percentage in sewage sludge, also has that energy consumption is low, the fireballing advantage of Treatment of Sludge.
To achieve these goals, the technical scheme that the present invention takes is to provide a kind of microwave method to process mud, including with
Lower step:
1) to liquefaction after mechanical sludge dewatering, 200-300 DEG C with sludge pump liquefaction after mud squeeze into settling apparatus/
Dehydration equipment, the mud after being dehydrated；
2) high temperature mud step 1 obtained is transported to microwave-heating reactor, in microwave-heating reactor, with 5 millis
M/min velocity of vibration high temperature mud is shaken, meanwhile, microwave-heating reactor is with the microwave radiation merit of 300 watts
Rate and the microwave frequency of 2000MHz, carry out microwave-heating to the high temperature mud of vibrations, and pyrolysis time is 40 minutes.
3) mud after pyrolysis is transported in cooler.
As a further improvement on the present invention, step 1) replace with-utilize heat exchanger and carry out heat recovery, then use
Sludge pump squeezes into settling apparatus/dehydration equipment the mud after liquefaction, to the mechanical sludge dewatering after liquefaction, after being dehydrated
Mud.
As a further improvement on the present invention, after step 3, also include: after obtaining final dry mud, when
When the wet mud of next batch is dried process, the sludge dry powder used is the dry mud obtained by step 3.
The invention has the beneficial effects as follows: the present invention, initially with heat treatment, uses microwave treatment, it is possible to significantly drop the most again
Low moisture percentage in sewage sludge, also has the advantage that Treatment of Sludge energy consumption is low, thus effectively facilitates recycling sludge.
Detailed description of the invention
Below in conjunction with and detailed description of the invention the present invention is further described.
The present invention provides a kind of microwave method to process mud, comprises the following steps:
1) to liquefaction after mechanical sludge dewatering, 200-300 DEG C with sludge pump liquefaction after mud squeeze into settling apparatus/
Dehydration equipment, the mud after being dehydrated；
2) high temperature mud step 1 obtained is transported to microwave-heating reactor, in microwave-heating reactor, with 5 millis
M/min velocity of vibration high temperature mud is shaken, meanwhile, microwave-heating reactor is with the microwave radiation merit of 300 watts
Rate and the microwave frequency of 2000MHz, carry out microwave-heating to the high temperature mud of vibrations, and pyrolysis time is 40 minutes.
3) mud after pyrolysis is transported in cooler.
Step 1) replace with-utilize heat exchanger and carry out heat recovery, then with sludge pump, the mud after liquefaction is squeezed into
Settling apparatus/dehydration equipment, to the mechanical sludge dewatering after liquefaction, the mud after being dehydrated.
After step 3, also include: after obtaining final dry mud, when the wet mud of next batch is done
During dry process, the sludge dry powder used is the dry mud obtained by step 3.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, it is also possible to make some simple deduction or replace, all should be considered as belonging to the present invention's
Protection domain.
