Abstract
The invention discloses a printing and dyeing sludge treatment method. The printing and dyeing sludge treatment method comprises the following steps: A, collecting and adding wet sludge generated by printing and dyeing into a high storage pool, and precipitating for solid-liquid separation; B, sending a separated solid phase into a low stirring and drying stove by virtue of gravity, and inflating high-temperature flue gas into the stirring and drying stove to dry the wet sludge into dry sludge; C, arranging a dry sludge discharging pipeline with a conveying fan at a discharging port of the stirring and drying stove, and conveying the dry sludge into a boiler for combustion through wind power by the discharging pipeline; and D, inflating one part of high-temperature flue gas generated during the combustion in the boiler into the stirring and drying stove as a heat source to dry the wet sludge, exhausting the other part of the high-temperature flue gas after flue gas treatment, and leading out ash residues after the combustion in the boiler. By the printing and dyeing sludge treatment method, the sludge generated by printing and dyeing is effectively treated through sufficient utilization of heat energy, the pollution is reduced, and the environment is protected.
Description
Technical field
The present invention relates to a kind of waste treatment technique, refer to especially a kind of textile dyeing sludge processing method.
Background technology
Along with the raising of people's living standard and the variation of mode of life, apparel industry develops rapidly, also so that the mud that produces in the cloth processing printing and dyeing treating processes is increasing, thereby environment protection has been caused very large pressure.Printing and dyeing sludge is different from other common mud, be characterized in containing a large amount of larger molecular organics fiber, excess dye and inorganic mineral, and water ratio is high, viscosity is high.At present, prior art is the method for disposal of taking simple and easy landfill mostly to this, but fiber hard degradation, inorganic mineral are difficult to compression, and the landfill heap is unstable, the easy stripping of the contained heavy metal of excess dye and polluted-water, thus caused very large harm to environment.
Summary of the invention
Technical problem to be solved by this invention is: a kind of rational textile dyeing sludge processing method is provided, and this treatment process takes full advantage of heat energy and effectively processes the mud that printing and dyeing produce, and has reduced pollution, has protected environment.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of textile dyeing sludge processing method, and it may further comprise the steps:
A. the wet mud that produces of will printing and dyeing is collected to join in the high-order storage pool and is precipitated solid-liquid separation;
B. solid phase after will separating relies on gravity to pass in the low level stirring and drying stove, passes into the high-temperature flue gas mud that will wet in the stirring and drying stove and is dried into siccative;
C. the discharge port place of stirring and drying stove arranges the siccative delivery conduit with conveying fan; This delivery conduit utilizes wind-force to be delivered in the boiler siccative to burn;
D. the part high-temperature flue gas that burning produces in the boiler passes in the stirring and drying stove and dries wet mud as thermal source, and another part high-temperature flue gas is discharged after flue gas is processed; Lime-ash after the boiler combustion is derived.
As a kind of preferred scheme, described high-temperature flue gas passes into the stirring and drying stove from stirring and drying furnace roof section and side respectively.
As a kind of preferred scheme, the upper end of described high-order storage pool is connected with High Pressure Air Pipe Line.
As a kind of preferred scheme, the high-temperature flue gas that boiler combustion produces passes in the gas-holder, and this gas-holder is communicated with high-order storage pool by described High Pressure Air Pipe Line.
After having adopted technique scheme, effect of the present invention is: because
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the embodiment of the invention;
In the accompanying drawing: 1. high-order storage pool; 2. the mud delivery conduit wets; 3. stirring and drying stove; 4. conveying fan; 5. siccative delivery conduit; 6. gas-holder; 7. boiler; 8. cleaning apparatus; 9. high-temperature flue gas drying pipeline; 10. High Pressure Air Pipe Line; 11. Drainage pipe.
Embodiment
The present invention is described in further detail below by specific embodiment.
As shown in Figure 1, a kind of textile dyeing sludge processing method, it may further comprise the steps:
A. the wet mud that produces of will printing and dyeing is collected to join in the high-order storage pool 1 and is precipitated solid-liquid separation; The position of this high position storage pool 1 is higher, wet mud precipitates in the pond, certain altitude has Drainage pipe 11 on the sidewall of high-order storage pool 1, after wet mud is stacked into certain degree, liquid in the pond progressively rises, when liquid height is higher than the interface of Drainage pipe 11, just flow out, until the interface height of the height of wet mud and Drainage pipe 11 maintains an equal level;
B. solid phase after will separating relies on gravity to pass in the low level stirring and drying stove 3, passes into the high-temperature flue gas mud that will wet in the stirring and drying stove 3 and is dried into siccative; Because the position of high-order storage pool 1 is high, wet mud can rely on gravity to enter into stirring and drying stove 3 by wet mud delivery conduit 2, but should guarantee that the connecting tube between high-order storage pool 1 and the stirring and drying stove 3 is as far as possible short, certainly, in order to accelerate its transfer rate, the upper end of its high-order storage pool 1 is provided with High Pressure Air Pipe Line 10, utilizes high-pressure air to promote wet mud and enters into stirring and drying stove 3, certainly, can also utilize the relatively more expensive equipment such as extruser.High Pressure Air Pipe Line 10 connects a high-pressure pump, and this high-pressure pump connects a gas-holder 6, and the high-temperature flue gas that boiler 7 burnings can be produced is passed in the gas-holder 6, is utilizing high-pressure pump to be driven in the high-order storage pool 1, namely carries out the drying work of part this moment.
C. the discharge port place of stirring and drying stove 3 arranges the siccative delivery conduit 5 with conveying fan 4; This delivery conduit utilizes wind-force to be delivered to burning in the boiler 7 siccative;
D. the part high-temperature flue gas that burning produces in the boiler 7 passes in the stirring and drying stove 3 and dries wet mud as thermal source, and another part high-temperature flue gas is discharged after flue gas is processed; Lime-ash after boiler 7 burnings is derived.A general supporting cleaning apparatus 8 in the boiler 7, the high-temperature flue gas that produces in the boiler 7 are first through utilizing after the dedusting.And these high-temperature flue gas pass into the stirring and drying stove 3 from stirring and drying stove 3 tops and side respectively by high-temperature flue gas drying pipeline 9, to guarantee stirring and drying stove 3 homogeneous heating.
