Description
Technical field
The present invention relates to the environmental protection field, specifically is a kind of device that utilizes pyrolysis technique to handle mud.
Background technology
Serious day by day along with environmental pollution, people's environmental consciousness is strengthening gradually.Now, the handling problem of mud has become a complex environment problem, how just can deal carefully with, and to accomplish real recycle, and being not only China also is that countries in the world are in the problem of constantly studying.China mainly is burning, farmland utilization, compost and landfill to sludge treatment at present, but their defectives that is arranged without exception itself.
Burn and to produce a large amount of carbonic acid gas and flue dust (containing heavy metal), increase the weight of the atmospheric environment load again.Because sludge moisture content is higher, calorific value lower (calorific value of dewatered sludge be about steam coal 1/3) could burn after must absorbing a large amount of heat energy, and the energy of processing modes such as sludge incineration input and fund certainty are greater than the income of energy recovery and material recycling.The farmland method has danger.The composting process floor space is big, and the treatment time is long.Landfill method can pollute underground water.
Mud thermolysis (pyrolysis) principle is exactly under oxygen-free environment, and the mud of drying is carried out heat, under the effect of destructive distillation and thermolysis, organism is converted into water vapour, non-condensable gases and charcoal.This treatment process also can be described as carbonization, and the difference of it and incineration treatment method maximum is to burn to be oxidizing reaction, and carbonization is reduction reaction.
The inner chamber of existing mud thermal decomposer decomposing furnace is an integral body, and heat exchange efficiency is low.And the temperature in the stove can only be integrally-regulated, can not adapt to complicated processing requirement, and production efficiency is low.
Summary of the invention
The invention provides a kind of novel mud thermal decomposer, by multilayer heating plate and scraper plate, improved heat exchange efficiency.
This device comprises the body of heater of a sealing, the body of heater upper end is provided with mud entrance and high-temperature gas outlet, there is harmless waste residue relief outlet the lower end, outer setting has the chuck of insulation usefulness, body of heater inside arranges the fixing heating plate of multilayer from top to bottom, the top of each heating plate is provided with scraper plate, and scraper plate links to each other with the mechanical rotating shaft of centre, can move together along with rotating shaft.
Further improve, an end of described heating plate is provided with baffle plate, and each heating plate adopts independently that heating tube is subjected to the adjusting of temperature control system as heating unit.
Further improve, the angle of the scraper plate setting of each layer scraper plate and its adjacent layers is interlocked.
Further improve, mechanical rotating shaft top connects motor, step-down gear, and the bottom links to each other with base bearing and fixes.
Further improve the high-temperature gas that the thermal source of described chuck adopts high-temperature gas outlet (2) to discharge.
Beneficial effect of the present invention is:
1, the mud below scraper plate drives on the heating plate moves, and improves the flowability of mud, improves heat exchange efficiency, reaches better decomposition effect.
2, each heating plate adopts independently heating unit, adopts temperature control system that the heating temperature of each heating plate can independently be set, and can regulate targetedly according to the difference of technology, the difference of material situation.
3, an end of heating plate arranges baffle plate, guarantees mud from the direction motion that sets and can not flow out to other position.
4, can regulate and control the rotating speed of mechanical rotating shaft as required; The mechanical rotating shaft bottom links to each other with base bearing and fixes, and it is steady to guarantee that rotating shaft is rotated.
5, the high-temperature gas that the inflammable gas burning after mud decomposes produces is adopted in the external jacket insulation, has better energy-conserving and environment-protective effect.

Fig. 2 is the vertical view of scraper plate and mechanical rotating shaft odd-level.
Fig. 3 is the vertical view of scraper plate and mechanical rotating shaft even level.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
The main mode of internal high temperature thermal degradation that adopts of this device is carried out thermolysis to mud.
Mud enters from the mud entrance 1 of upper of furnace body, decomposing the waste residue relief outlet 4 that passes through the lower end after finishing discharges, the gas that reduction reaction produces is discharged by high-temperature gas outlet 2, and outer setting has the chuck of insulation usefulness, uses high-temperature gas to export 2 expellant gas and is incubated.
Thermal decomposer inside arranges the fixing heating plate 5 of multilayer from top to bottom, each heating plate 5 adopts independently heating unit, be connected with heating tube 7, adopt temperature control system that the heating temperature of each heating plate 5 can independently be set, can regulate targetedly according to the difference of technology, the difference of material situation; Simultaneously the end at heating plate 5 arranges baffle plate 8, guarantees mud from the direction motion that sets and can not flow out to other position.
The top of heating plate 5 arranges a plurality of resistant to elevated temperatures scraper plates 6, and scraper plate 6 links to each other with mechanical rotating shaft 3, can move together along with mechanical rotating shaft 3, thereby the mud below driving on the heating plate 5 moves, improve the flowability of mud, improve heat exchange efficiency, to reach better decomposition effect; The angle that arranges of the scraper plate 6 of each layer scraper plate 6 and its adjacent layers is all interlocked, such as: the scraper plate 6 of odd-level is set to inwards, promote mud on the heating plate 5 to internal motion, even level 6 scraper plate outwards be set to, the mud on the promotion heating plate 5 outwards moves.
Thermal decomposer inner rotation mechanism adopts driven by motor mechanical rotating shaft 3, and mechanical rotating shaft 3 tops connect motor, step-down gear, can regulate and control the rotating speed of mechanical rotating shaft 3 as required; Mechanical rotating shaft 3 bottoms link to each other with base bearing and fix, and it is steady to guarantee that rotating shaft is rotated.
The concrete application approach of the present invention is a lot, and the above only is preferred implementation of the present invention, should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
