The vertical multi-disk sludge drying system disclosed by the utility model has the beneficial effects that the vertical multi-disk sludge drier has no moving parts, and therefore, the sludge drying system is convenient to maintain; a heat source of the waste heat boiler is adopted for carrying out indirect heating, so that an effect of efficient heat energy recycling is achieved, therefore, the moisture content of sludge can be quickly reduced; the sludge drying system is equipped with an air circulation system, so that moisture evaporated from sludge is quickly taken away; and the vertical multi-disk sludge drying system disclosed by the utility model adopts a full-closed system and provided with an air purification system, so that the secondary pollution of sludge is reduced, and dried sludge can meet the requirements of resource utilization.
Description
Technical field
The utility model relates to a kind of vertical polydisc sludge drying system, belongs to the environmental protection technical field of sludge treatment.
Background technology
Along with the urbanization process of China is accelerated, industrial developing rapidly, the increase of urban population, the quantity discharged of urban industry waste water and sanitary sewage is increasing, and treatment rate of domestic sewage also improves year by year, and 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.According to statistics, the town sewage treatment facility that puts into operation in the existing whole nation is thousands of seats altogether, the annual mud (dry weight) that produces is more than 1,000 ten thousand tons, and annual growth nearly 10%, the processing disposal costs of sewage sludge is higher, in whole construction costs of wastewater treatment in China factory, account for 20%～50% for the treatment of mud.The composition of sewage sludge is very complicated, except containing a large amount of moisture, also contains a large amount of useful resources.Have at present multiplely for urban sludge treating method, landfill, burning and comprehensive utilization are generally arranged, but before recycling, need carry out pre-treatment to mud, nurse one's health, comprise concentrated, dehydration, drying.Mud through 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, also should avoid problem of secondary pollution in drying process.
The utility model content
The purpose of this utility model is to provide a kind of vertical polydisc sludge drying system, utilize the thermal source indirect heating, can further reduce moisture percentage in sewage sludge, have high efficient heat recovery and emission-control equipment, level of automation is high, effectively avoids the characteristics of problem of secondary pollution.
The purpose of this utility model is achieved through the following technical solutions: a kind of vertical polydisc sludge drying system, mainly comprise dewatered sludge storehouse, vertical polydisc sludge drying machine, waste heat boiler, water cooler, dewatered sludge storehouse, mixing screw, cyclonic separator, cooling tower, blower fan, exhaust gas treating tower, it is characterized in that: be provided with outfeed belt conveyor between described vertical polydisc sludge drying machine and water cooler; Described mixing tank discharge port is connected with the desiccation machine opening for feed.
Further, described vertical polydisc sludge drying machine upper end is provided with stirrer.
In sum, the beneficial effects of the utility model are: utilize waste heat boiler thermal source indirect heating, have high efficient heat recovery, can reduce rapidly moisture percentage in sewage sludge; 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 air-purification system, has reduced the secondary pollution of mud, and after mummification, mud can arrive the requirement of recycling.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
Embodiment: as shown in Figure 1, the utility model mainly comprises dewatered sludge storehouse 1, vertical polydisc sludge drying machine 3, waste heat boiler 4, water cooler 7, dewatered sludge storehouse 9, mixing screw 10, cyclonic separator 11, cooling tower 12, blower fan 13, exhaust gas treating tower 14, it is characterized in that: be provided with outfeed belt conveyor 8 between described vertical polydisc sludge drying machine 3 and water cooler 7; Described mixing tank discharge port 18 is connected with desiccation machine opening for feed 19.
Further, described vertical polydisc sludge drying machine 3 upper ends are provided with stirrer 17.
Principle of work of the present utility model: after the mud of sewage work carries out thickening, water ratio is that 80～85% mud enters dewatered sludge storehouse 1, feeding conveyor 2 with sludge lifting to vertical polydisc sludge drying machine 3 inside, mud contacts with drying tray from top to bottom, 85 ℃ of vertical polydisc sludge drying machine 3 inner drying temperature, the mud granule of generation is recycled gas fluidized and produces fierce mixing.Owing to relying on the thermal capacity of himself in fluidized-bed, residence time is long and product amount is large, takes mud particulate and dust out of fluidized layer with the gas of circulation, and mud granule is delivered to water cooler 7 by discharging conveying belt 5, condense to less than 40 ℃, deliver to dewatered sludge storehouse 9 by outfeed belt conveyor 8.Dust, mud particulate separate at cyclonic separator 11 with fluidizing agent, dust, mud particulate pass through metering screw conveyer, be transported to mixing screw 10 from ash silo and mix with dewatered sludge, and send back to again vertical polydisc sludge drying machine 3 by worm conveyor.The fluidizing agent of dryer system and chiller system all remains on a confining gas loop.Recycle gas takes away vertical polydisc sludge drying machine 3 with the moisture of mud particulate and evaporation.The mud particulate is in the interior separation of cyclonic separator 11, and the moisture of evaporation carries out condensation the direct adverse current water spray of the interior employing of cooling tower 12 mode.Moisture and other recycle gas of evaporation are cooled to 60 ℃ from 85 ℃ of left and right, then condensation, the water that condensation is got off leaves recycle gas and flow back into the sewage diposal area, in cooling tower 12, clean and cooling fluidizing agent is got back to again vertical polydisc sludge drying machine 3, and a part of discharging waste gas enters discharges after exhaust gas treating tower 14 is processed.
As mentioned above, just can realize preferably the utility model.
