Description
Technical field
The utility model relates to energy-conserving and emission-cutting technology field, specifically a kind of novel recycling system of sludge.
Background technique
During municipal sewage treatment, it is always faced with the problem of how disposing sludge.The side of traditional sludge processing
Formula has land use and Sludge landfill.Because sludge is easily corrupt, foul smelling, and contain a small amount of heavy metal ion, at traditional sludge
Reason mode easily causes secondary pollution, and irreversible severe can be caused to injure when serious to soil.
In autumn and winter, the unboiled water temperature of thermal power plant boiler make-up water is lower, and about 0~5 DEG C or so.Lower unboiled water temperature
Degree will affect the water-flowing amount of boiler feed water system reverse osmosis membrane, it usually needs low temperature unboiled water temperature is increased to 25 DEG C or so.
Currently, mode of the boiler feedwater unboiled water heating of domestic steam power plant frequently with steam-water heat exchanging, resource consumption are larger.
Therefore, there are also to be developed for the prior art.
Utility model content
Place in view of above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of novel recycling benefits of sludge
Use system.Aim to solve the problem that the existing sludge treating system wasting of resources, stability is poor, pollute natural environment the problem of.
In order to achieve the above object, the utility model takes following technical scheme:
The utility model provides a kind of novel recycling system of sludge, including feeding device, boiler, makeup water pretreatment
System characterized by comprising wet mud storehouse, screw pump, flue gas heat-exchange unit, drying machine, sludge cooler, dewatered sludge storehouse, on
Expect device；The wet mud storehouse, screw pump, flue gas heat-exchange unit, drying machine, sludge cooler, dewatered sludge storehouse, feeding device and pot
Furnace is sequentially connected by pipeline；The exhaust outlet of the boiler connects the flue entrance of flue gas heat-exchange unit by pipeline；The sludge
The low temperature unboiled water entrance of cooler connects raw water pipe, the high temperature unboiled water outlet connection makeup water pretreatment system of sludge cooler
Water inlet, makeup water pretreatment system water outlet connection boiler supply water inlet.
Further, the screw pump uses single-screw (single screw) pump.
Further, the feeding device uses screw conveyor.
Further, the flue entrance of the flue gas heat-exchange unit is arranged on chimney heat exchanger top.
The utility model is compared with prior art: reducing pollution of the sludge to environment, improves the benefit of resource and energy
With rate, is heated, reduced during heating unboiled water by unboiled water (water at low temperature) of the high temperature drying sludge to boiler feed water system
Steam consumption quantity, and then combustion the consumption of coal is reduced, reduce the discharge of the pollutants such as nitrogen oxides, realize the saving of the energy, drops
Low operating cost.
Detailed description of the invention
Fig. 1 is the flow diagram of the utility model sludge recovery system.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
As shown in Figure 1, being a kind of novel recycling system of sludge, including feeding device 7, boiler 8, makeup water pretreatment
System 9 characterized by comprising wet mud storehouse 1, screw pump 2, flue gas heat-exchange unit 3, drying machine 4, sludge cooler 5, dry dirt
Hopper dredger 6, feeding device 7；The wet mud storehouse 1, screw pump 2, flue gas heat-exchange unit 3, drying machine 4, sludge cooler 5, dewatered sludge
Storehouse 6, feeding device 7 and boiler 8 are sequentially connected by pipeline；The exhaust outlet of the boiler 8 connects flue gas heat-exchange unit 3 by pipeline
Flue entrance；The low temperature unboiled water entrance of the sludge cooler 5 connects raw water pipe, and the high temperature unboiled water of sludge cooler 5 goes out
The make-up water of the water inlet of mouth connection makeup water pretreatment system 9, the water outlet connection boiler 8 of makeup water pretreatment system 9 enters
Mouthful.
Further, the screw pump 2 uses single-screw (single screw) pump.
Further, the feeding device 7 uses screw conveyor.
Further, the flue entrance of the flue gas heat-exchange unit 3 is arranged on 3 top of chimney heat exchanger.
When utility model works, sludge is discharged in wet mud storehouse 1, is firstly transferred to flue gas heat-exchange unit 3, pot through screw pump 2
The high-temperature flue gas that fire grate goes out enters the flue of flue gas heat-exchange unit 3 by flue, is tentatively heated to wet mud, wet mud passes through
Enter in drying machine 4 after flue gas heat-exchange unit 3, further being heated by the high-temperature steam in drying machine 4 becomes high temperature drying sludge, high
The dry sludge of temperature enters sludge cooler 5, and low temperature unboiled water enters sludge cooler 5, while reducing dry sludge temperature, improves
The water temperature of unboiled water, improves the unboiled water outflow sludge cooler of water temperature, and enters the water inlet of makeup water pretreatment system 9, warp
Become demineralized water after crossing filtering and heating processing, demineralized water flows into the make-up water water inlet of boiler 8, becomes the make-up water of boiler 8；Drop
Drying sludge after low temperature is defeated to be stored into dewatered sludge storehouse 6, and when boiler 8 needs fuel, dewatered sludge storehouse 6 is discharged sludge and enters
Feeding device 7 is delivered in boiler 8 through feeding device 7, after being sufficiently mixed in boiler 8 with fire coal, becomes the fuel of boiler 8.
