Description
Technical field
The utility model relates to field of Environment Protection, specifically a kind of device that utilizes the pyrolysis technique lignin-sludge.
Background technology
Day by day serious along with environmental pollution, people's environmental consciousness is strengthening gradually.Now, the processing 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 is also that countries in the world are in the problem of constantly studying.China is mainly burning, farmland utilization, compost and landfill to sludge treatment at present, but their defects that is arranged without exception itself.
Burn and can produce a large amount of carbonic acid gas and flue dust (containing heavy metal), again increase the weight of the atmospheric environment load.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 that the processing modes such as sludge incineration drop into and fund must be greater than the income of energy recovery and material recycling.The farmland method has danger.The composting process floor space is large, and the treatment time is long.Landfill method can pollute underground water.
It is exactly under oxygen-free environment that sludge hot decomposes (pyrolysis) principle, and dry mud is carried out to heat, under the effect of destructive distillation and thermolysis, organism is converted into to 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 as oxidizing reaction, and carbonization is reduction reaction.
The inner chamber of existing sludge hot decomposer decomposing furnace is an integral body, and heat exchange efficiency is low.And the temperature in stove can only be integrally-regulated, can not adapt to complicated processing requirement, production efficiency is low.
The utility model content
The utility model provides a kind of novel sludge hot decomposer, by Multi-layer warming dish and scraper plate, has 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 lower end, outer setting has the chuck of insulation use, 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 is connected with middle mechanical rotating shaft, 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 heating tube as heating unit, to be subject to the adjusting of temperature control system.
Further improve, the angle of the scraper plate setting of every one deck scraper plate and its adjacent layers is interlocked.
Further improve, mechanical rotating shaft top connects motor, step-down gear, and bottom is connected and is fixed with base bearing.
Further improve the high-temperature gas that the thermal source of described chuck adopts high-temperature gas outlet (2) to discharge.
The beneficial effects of the utility model are:
1, the mud that scraper plate drives on following heating plate is moved, and improves the mobility 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 technique, the difference of material situation.
3, an end of heating plate arranges baffle plate, guarantees that mud moves and can not flow out to other position from the direction set.
4, can regulate and control as required the rotating speed of mechanical rotating shaft; The mechanical rotating shaft bottom is connected and is fixed with base bearing, guarantees that rotating shaft is rotated steady.
5, the high-temperature gas that the inflammable gas burning after external jacket insulation employing sludge disintegration produces, have better energy-conserving and environment-protective effect.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The vertical view that Fig. 2 is scraper plate and mechanical rotating shaft odd-level.
The vertical view that Fig. 3 is scraper plate and mechanical rotating shaft even level.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
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, waste residue relief outlet 4 by lower end after having decomposed is discharged, the gas that reduction reaction produces exports 2 by high-temperature gas and discharges, and outer setting has the chuck of insulation use, uses high-temperature gas to export 2 expellant gas and is incubated.
Thermal decomposer inside arranges the fixing heating plate of multilayer 5 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 technique, the difference of material situation; An end at heating plate 5 arranges baffle plate 8 simultaneously, guarantees that mud moves and can not flow out to other position from the direction set.
The top of heating plate 5 arranges a plurality of resistant to elevated temperatures scraper plates 6, and scraper plate 6 is connected with mechanical rotating shaft 3, can move together along with mechanical rotating shaft 3, thereby the mud driven on following heating plate 5 is moved, improve the mobility of mud, improve heat exchange efficiency, to reach better decomposition effect; The angle that arranges of the scraper plate 6 of every one deck 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 heating plate 5 to internal motion, even level 6 scraper plate outwards be set to, the mud on 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 as required the rotating speed of mechanical rotating shaft 3; Mechanical rotating shaft 3 bottoms are connected and are fixed with base bearing, guarantee that rotating shaft is rotated steady.
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
