Particularly: said main drain is communicated with the cavity of setting in quill shaft one end, blade spindle thermal medium inlet place, and the water of condensation output mechanism is set in this cavity.
In said sludge drying equipment work process, the blade angle that is fixed on blade on two blade spindles staggers 90 ° each other, and two modes that blade spindle all adopts ecto-entad to rotate.
The working order of said drive unit is by the VFC device control.
Cover on said and also be provided with maintenance top cover, carrier gas inlet and manhole.
Said vapour outlet is communicated with Cyclonic separating apparatus, water dust scrubber and the incineration system of peripheral hardware successively.
A kind of and the supporting sludge drying technology of aforesaid device; It is characterized in that this technology is: with water ratio at mud pre-treatment to the water ratio more than 80% below 50%, keep mud temperature-resistant; It is imported a sludge drying equipment; In this sludge drying equipment, mud is constantly promoted to discharge port, and mud is heated to more than 120 ℃, and accompany by lasting stirring, break process; To constantly draw by the water vapor that volatilizes in the mud simultaneously with air inducing equipment, to the mud that contains required water ratio by discharging in this sludge drying equipment.
Further say: the tail gas that the water vapour of from sludge drier, being drawn by air inducing equipment is produced after dust removal process is transfused to incineration system.
The concrete grammar of said dust removal process is:
The water vapour input Cyclonic separating apparatus that at first will from sludge drier, draw; Remove big dust particle contained in the water vapour; Then water vapour is imported water dust scrubber and remove fine dusts, the tail gas input incineration system that will after above-mentioned dust removal process, be generated at last.
In the process with water dust scrubber treating water steam, spray water is back to an inclined-plate clarifying basin, after precipitation process, is re-entered in the water dust scrubber by handling equipment again, realizes the recycle of spray water.
To the deficiency of prior art, and high according to moisture percentage in sewage sludge, and viscosity is big; Difficult exsiccant characteristics, this case contriver is through studying for a long period of time and put into practice, the special sludge drying technology that proposes the utility model; It is through adopting the secondary drying method, and making sludge drying handle can more smooth and easyly carry out easily, and the sludge drying degree is more controlled; Mud handling capacity is bigger, and does not have the anxiety that causes secondary pollution.Particularly; Promptly before the mud high to water ratio carries out drying and other treatment; At first it is carried out pre-treatment, its water ratio is adjusted to the scope of being convenient to the sludge drying device processes, then with sludge drying equipment it is carried out secondary treatment again; And in secondary treatment; Adopt air inducing equipment to draw steam and other materials that volatilizes in the mud, and above-mentioned steam and other materials are carried out dedusting, burning disposal, thoroughly eliminated the hidden danger that sludge drying technology possibly cause secondary pollution with Cyclonic separating apparatus, water dust scrubber and incineration system.
This case contriver improves sludge drying equipment, as:
One of which, for driving arrangement (mainly being motor etc.), the utility model adopts the variable frequency adjustment mode, and it has following advantage:
