Description
Technical field
The utility model relates to technical field of sludge treatment, particularly a kind of sludge treating system.
Background technology
Along with development that is industrial and city, the output of China city and industrial and mining enterprises' mud sharply increases.Contain kind pollutent widely in city and industrial and mining enterprises' mud, great harm is caused to environment.The disposal of countries in the world to mud is long-standing, its traditional method of disposal mainly contains sanitary landfill, sludge incineration, Land_use change, Ocean dumping etc., lay particular emphasis on sludge incineration and Land_use change to the disposal of mud abroad, sanitary landfill and Ocean dumping have started to step down from the stage of history gradually.
Along with the continuous increase of city and industrial and mining enterprises' sewage load, sludge treatment has become thorny problem, particularly prior art does not reach the requirement of minimizing, stabilization, innoxious, resource utilization for many cities and industrial and mining enterprises' sewage sludge disposal, and there is secondary pollution problem.If by mode process such as former direct landfills, environmental protection cannot be up to standard, and the Sludge Disposal Techniques Given this, a kind ofly meet national policy, being applicable to China's actual conditions needs research and development badly.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of sludge treating system, which saves cost of disposal, decreases transport and processing links pollution on the environment, has saved the energy, and improve the utilization ratio of pyrolysis product.
The utility model solves the technical scheme that its technical problem adopts: a kind of sludge treating system, it is characterized in that, comprise the comminuting dasher, the first screw rod conveyor, thin layer evaporator, the second screw rod conveyor, disc dryer, electricity slurry pyrolysis oven and the exhaust processor that set gradually, described electricity slurry pyrolysis oven needs external power source to provide power, it is also connected with the belt residue receiving tank for collecting residue, and described disc dryer is connected with boiler with thin layer evaporator.
Preferably, mud Noodle forming machine is provided with between described first screw rod conveyor and thin layer evaporator.
Preferably, interchanger and condenser is also provided with between described electricity slurry pyrolysis oven and exhaust processor, disc dryer, thin layer evaporator, mud Noodle forming machine, interchanger and condenser is sent to successively, finally by exhaust processor process through pipeline from electricity slurry pyrolysis oven high-temperature gas mixture body out.
Preferably, described interchanger and condenser are connected with condensation pond respectively.
Positively effect of the present utility model: the utility model adopts sludge drying and the burning facility of mature and reliable, and system operation reliability is high; Effectively can reduce mud handling capacity, the waste produced after process has glass and metal lime-ash, without dust in treating processes; Because mud carries out the pyrolysis of electricity slurry after carrying out secondary mummification again, not that this greatly reduces power consumption, has effectively stopped the waste of the energy directly to wet sludge incineration in traditional technology; The heat of the mixed flue gas simultaneously produced after the utility model pyrolyzing sludge utilize by anhydration system, effectively prevent the waste of the energy; In the pyrolysis of electricity slurry, the temperature of electrode is easy to control, and flameholding, effectively can control the generation of the organic pollutants such as dioxin.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of sludge treating system of the utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
With reference to Fig. 1, the utility model preferred embodiment provides a kind of sludge treating system, it is characterized in that, comprise the comminuting dasher, the first screw rod conveyor, mud Noodle forming machine, thin layer evaporator, the second screw rod conveyor, disc dryer, electricity slurry pyrolysis oven and the exhaust processor that set gradually, described electricity slurry pyrolysis oven needs external power source to provide power, it is also connected with the belt residue receiving tank for collecting residue, and described disc dryer is connected with boiler with thin layer evaporator.
Mud Noodle forming machine is provided with between described first screw rod conveyor and thin layer evaporator.
Interchanger and condenser is also provided with between described electricity slurry pyrolysis oven and exhaust processor, disc dryer, thin layer evaporator, mud Noodle forming machine, interchanger and condenser is sent to successively through pipeline, finally by forming clean gas after exhaust processor process and being discharged from electricity slurry pyrolysis oven high-temperature gas mixture body out.
Described interchanger and condenser are connected with condensation pond respectively so that the water of condensation formed after heat exchange or condensation to be collected in condensation pond in time for subsequent use.
When using the utility model, dewatered sludge (granule sludge from disc dryer), dry ground and wet mud enter into comminuting dasher in charging place to carry out stirring and pulverizing, wherein dry ground and dewatered sludge and wet mud mix and mainly make wet mud be easy to shaping, are convenient to access arrangement, charging after pulverizing is transported to mud Noodle forming machine by the first screw rod conveyor and crushes and forming surface strip (being convenient to charging and mummification), one-level mummification is carried out through thin layer evaporator, deliver in disc dryer through the second screw rod conveyor again, wherein thin layer evaporator and the heat needed for disc dryer mainly from boiler, from mud Noodle forming machine and thin layer evaporator mud drying eliminate the moisture of 40-50%, carry out secondary mummification after entering disc dryer, moisture is removed again about 10-20%, mud after secondary mummification enters electricity slurry pyrolysis oven, residue (being mainly glass and metal) and high-temperature gas mixture body is formed after pyroprocessing, wherein residue is rationally deposited or landfill after belt residue receiving tank is collected, high-temperature gas mixture is admitted to garden dish drying machine successively through pipeline, thin layer evaporator and mud Noodle forming machine, its heat content is fully utilized, for removing the moisture in water-containing sludge, the water of condensation that the water vapour formed when removing moisture is formed after interchanger and condenser cooling is collected by condensation pond and is used in order to him, wherein the Main Function of interchanger reclaims the unemployed heat in mixed gas, avoid the waste causing the energy.The effect of exhaust processor is gas that is nitrogenous in process mixed gas and oxysulfide, is finally discharged by the clean gas obtained after treatment.
Above-describedly be only preferred embodiment of the present utility model; be understood that; the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping; and be not used in restriction protection domain of the present utility model; all any amendments, equivalent replacement etc. made within thought of the present utility model and principle, all should be included within protection domain of the present utility model.
