The flash dry sludge is utilized, so that the energy utilization rate is improved, and an air circulating system is arranged, so that high-efficiency heat recovery and waste gas treatment are achieved, the automatic degree is high, the moisture content of the sludge can be further reduced, and secondary waste gas pollution is effectively avoided.
Description
Technical field
The utility model relates to a kind of Flash Type sludge dry system, belongs to environmental protection technical field of sludge treatment.
Background technology
Along with the quantity discharged of sewage is increasing, wastewater treatment rate also improves year by year, and particularly the sludge yield of municipal sewage plant also sharply increases.A large amount of excess sludges will discharge in sewage work, and the mud of enormous amount need to be done further processing, if mud can not get reasonable processing, will cause secondary pollution.The processing disposal costs of sewage sludge is higher, in whole construction costs of sewage work, for the treatment of mud, accounts for 20%～50%.The composition of sewage sludge is very complicated, except containing a large amount of moisture, also containing a large amount of useful resources.For urban sludge treating method, have at present multiplely, generally have landfill, burning and comprehensive utilization, but before recycling, need carry out pre-treatment to mud, nurse one's health, comprise concentrated, dehydration, dry.Mud after mummification, can apply to land reclamation, building materials utilization etc.How to reduce the water ratio of mud, this is the vital task of sludge treatment, in drying process, also should avoid problem of secondary pollution.
Summary of the invention
The purpose of this utility model is to provide a kind of Flash Type sludge dry system, utilize flash distillation dewatered sludge, improve energy utilization rate, is furnished with air circulation system, there is high efficient heat recovery and off gas treatment, level of automation is high, can further reduce moisture percentage in sewage sludge, the feature of effectively avoiding secondary exhaust emission to produce.
The purpose of this utility model is achieved through the following technical solutions: a kind of Flash Type sludge dry system, mainly comprises: wet mud mud machine, mixing tank, Flash Type drying sludge, cyclonic separator, roasting kiln, gas blower, exhaust gas cleaner, dewatered sludge transfer roller; It is characterized in that: described wet mud mud machine mud outlet end connects mixing tank, and mixing tank is positioned at the top of Flash Type drying sludge; Described Flash Type drying sludge is provided with cage shredder; The top exit of described Flash Type drying sludge is connected with the import of cyclonic separator by pipeline.
The outlet of described cyclonic separator is connected with steam fan, roasting kiln successively by pipeline.
The bottom of described cyclonic separator is provided with dewatered sludge transfer roller.
Described roasting kiln connects the inlet mouth of Flash Type drying sludge by heating pipe.
In sum, the beneficial effects of the utility model are: utilization is wet, dewatered sludge is blended in the rapid mummification of Flash Type drying sludge, can reduce rapidly moisture percentage in sewage sludge, improves energy utilization rate; And be furnished with air circulation system, take away rapidly the moisture of mud evaporation; The utility model adopts totally-enclosed system, is provided with flare system, has reduced the secondary pollution of mud, and after mummification, mud can arrive the requirement of recycling.
