A kind of sludge treatment equipment
Technical field
This utility model relates to field of sludge treatment, is specially a kind of sludge treatment equipment.
Background technology
Deeply dehydrating sludge technology can effectively reduce moisture percentage in sewage sludge, reduce outward transport sludge quantity, be widely used in China, but generally added substantial amounts of iron salt (such as: ferric chloride or bodied ferric sulfate etc.), mud butt increment is big, also limit follow-up end treatment approach simultaneously.Mummification-the heat treatment of mud (burns, carbonization) process route can decompose the Organic substance in mud thoroughly, the poisonous and harmful substance such as curing heavy metal simultaneously, but owing to the moisture content of feed sludge is higher, the energy that heat treatment produces is not sufficient to provide the thermal source needed for the mummification of front end, therefore interpolation oil is generally required, the external energy such as natural gas or coal, enable the mud after mummification that moisture content to be reduced to the relatively low scope required by heat treatment charging, therefore higher to the operating and maintenance requirements of equipment, operating cost is high, there is the risk of the tail gas pollutions such as two English simultaneously.Pyrolyzing sludge/carbonization technology is under conditions of anaerobic or anoxia, Organic substance in mud is decomposed into combustible gas, fluid oil and solid-state charcoal, and tail gas amount is few, and the risk producing two English is low, product purpose is extensive, can do chemical conditioner, Snow Agent, soil conditioner, fuel, adsorbent etc..But product quality is relatively low, added value is the highest, limits its popularization and application.
Summary of the invention
The purpose of this utility model is to provide a kind of sludge treatment equipment, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of sludge treatment equipment, including main body, described body top is provided with charging aperture, described body interior is disposed with conditioning layer, dehydration layer, crushable layer, baking zone and carbide furnace, described conditioning layer left end top is provided with additive inlet port, it is provided with shaft in the middle part of described conditioning layer, on the right side of described body exterior, shaft one end opposite position is provided with motor, it is provided with drying unit in the middle part of described baking zone, described baking zone surrounding is provided with steam pipe, it is connected by siphunculus between described steam pipe and carbide furnace, in the middle part of described siphunculus and be positioned at body exterior and be provided with heat exchanger.
Further, described dehydration layer is internally provided with filter press, and mud adds iron content coagulant (such as ferric chloride, bodied ferric sulfate, ferrous sulfate etc.) before entering pressure filter and nurses one's health.
Further, described crushable layer is internally provided with disintegrating machine and comminutor.
Further, described carbide furnace left end is provided with discharging opening.
Further, described conditioning layer, dehydration layer, crushable layer, be connected with each other by conduit respectively between baking zone and carbide furnace.
Further, described shaft is provided with stirring vane.
Compared with prior art, the beneficial effects of the utility model are:
A kind of sludge treatment equipment of the present utility model, by arranging conditioning layer at body top, the dewatering efficiency of mud can be improved, it is provided with crushable layer and can reduce the dust in follow-up sludge treatment device, and heat exchanger is set at body exterior, maximally utilizing of resource can be realized, reduce adding of external energy, thus significantly reduce the mummification cost of mud, mud after mummification is carried out in retort anoxia/Non-oxygen pyrolytic reaction simultaneously, can iron oxides be loaded on sludge-based activated carbon, make a kind of broad-spectrum environmental protection material, there is higher economy and social value.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, a kind of technical scheme of this utility model offer: a kind of sludge treatment equipment, including main body 1, described main body 1 top is provided with charging aperture 3, described main body 1 is internal is disposed with conditioning layer 2, dehydration layer 5, crushable layer 6, baking zone 7 and carbide furnace 10, described conditioning layer 2 left end top is provided with additive inlet port 4, it is provided with shaft 11 in the middle part of described conditioning layer 2, on the right side of described main body 1 outside, shaft 11 one end opposite position is provided with motor 12, it is provided with drying unit 8 in the middle part of described baking zone 7, described baking zone 7 surrounding is provided with steam pipe 16, it is connected by siphunculus 14 between described steam pipe 16 and carbide furnace 10, in the middle part of described siphunculus 14 and be positioned at that main body 1 is outside is provided with heat exchanger 15.
Described dehydration layer 5 is internally provided with filter press.
Described crushable layer 6 is internally provided with disintegrating machine and comminutor.
Described carbide furnace 10 left end is provided with discharging opening.
Described conditioning layer 2, dehydration layer 5, crushable layer 6, it is connected with each other by conduit 13 respectively between baking zone 7 and carbide furnace 10.
It is provided with stirring vane on described shaft 11.
In sum, this utility model by arranging conditioning layer 2 at main body 1 top, the dewatering efficiency of mud can be improved, it is provided with crushable layer 6 and can reduce the dust in follow-up sludge treatment device, and heat exchanger 15 is set outside main body 1, maximally utilizing of resource can be realized, reduce adding of external energy, thus significantly reduce the mummification cost of mud, mud after mummification is carried out in retort anoxia/Non-oxygen pyrolytic reaction simultaneously, can iron oxides be loaded on sludge-based activated carbon, make a kind of broad-spectrum environmental protection material, there is higher economy and social value.
Embodiment the most of the present utility model, for the ordinary skill in the art, being appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can carry out multiple change, revise, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
