Description
Technical field
The utility model relates to a kind of sludge treatment device, particularly a kind of sludge treatment device.
Background technology
" mud " this concept refers to a kind of viscous mixt consisting of water and the solid matter that is derived from sewage being dispersed in water.The sludge problem that we face, refer to be exactly all kinds of sewage works thickened sludge after pretreatment, the mud of water ratio between 75-90%.High-moisture percentage be mud as a kind of topmost feature of solid waste pollutent, and just because of the existence of large quantity of moisture, being mud has the hazardness in eye more than other forms of solid waste thing.The high-moisture percentage of mud is the topmost technical barrier running in whole sludge stabilizing, minimizing, harmlessness disposing.
In order to carry out economy and the processing of environmental protection to this mud, must successively by dehydration and drying treatment, its water content be decreased to a clear and definite value.After processed, water content generally can be reduced to the degree that makes mud be semi-solid state or shot shape, and the target of drying sludge is still to residue in the moisture in mud after removing dehydration as far as possible completely.Dried mud can offer energy recovery equipment generating and/heating, or be separately used as him, for example, as fertilizer.
The integrated deep dehydration desiccation machine of a kind of mud is disclosed in prior art, its publication number is: CN203128381, it comprises flocculation plant, folded spiral shell formula sludge dewatering equipment, the output terminal of described flocculation plant is connected with folded spiral shell formula sludge dewatering equipment input terminus, and the output terminal of folded spiral shell formula sludge dewatering equipment is connected with gear type sludge dryer.Its weak point is, gear type sludge dryer heats mud by screw shaft, and this device drying efficiency is lower, and this structure is higher to sealing requirements, and this has just strengthened maintaining and has obtained cost.
Separate type heat pipe exchanger is a kind ofly to utilize the vaporization of working medium to realize heat transmission, separate type heat pipe exchanger is that the evaporator section of heat pipe and condensation segment is arranged apart, be not in an integral body together, with vapor uptake, be connected with condensate descending, can be applicable to cold and hot fluid apart from each other or cold and hot fluid and absolutely not allow the occasion of mixing.
Utility model content
The purpose of this utility model is to provide a kind of drying sludge treatment system, improves drying efficiency, reduces working accuracy, reduces maintenance cost.
The purpose of this utility model is achieved in that a kind of drying sludge treatment system, comprise flocculation plant, folded spiral shell formula sludge dewatering equipment, the output terminal of described flocculation plant is connected with folded spiral shell formula sludge dewatering equipment input terminus, the output terminal of described folded spiral shell formula sludge dewatering equipment is connected with sludge drying device, described sludge drying device comprises drying unit and cooling unit, described drying unit comprises the laminar foraminous conveyer being arranged in loft drier, between foraminous conveyer, be provided with circulation air path, the input terminus of circulation air path is connected with heating container, in described heating container, be provided with separate type heat pipe exchanger condensation segment and recirculation blower, the output terminal of circulation air path is communicated with respectively air and heating container, described loft drier bottom output terminal is connected with cooling unit, cooling unit comprises the multi-layer intercrossed slanted screen plate being arranged in cooling tank.
The utility model when work, mud through the folded spiral shell of former process out after, by transfer roller, after even distributor refining, send into drying unit, mud is advanced with foraminous conveyer; Cold wind enters centrifugal blower from heating container wind-supplying mouth, after separate type heat pipe exchanger heating, enters loft drier, and hot blast penetrates sludge blanket in loft drier, fully contact with wet mud, carry out caloic exchange, the moisture in mud is evaporated to water vapor, takes away together with warm air; Dried mud is sent into cooling unit, and mud slowly moves down in case, thereby makes mud obtain sufficient cooling drying.Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, drying process is carried out heat exchange realization by the hot blast of sending with separate type heat pipe exchanger, lower to sealing requirements, thereby requirement on machining accuracy is lower, this has just reduced use cost, simultaneously, by hot blast and mud, directly carry out heat exchange, its drying efficiency is high.The utility model can be used in being dried of mud.
In order further to improve drying efficiency, described foraminous conveyer comprises the transmission net that is arranged on conveying belt below, is provided with some flitch of taking off on described conveying belt.
