Description

A kind of sludge drying belt filter press
Technical field
The utility model relates to a kind of sludge drying belt filter press, belongs to the environmental protection technical field of sludge treatment.
Background technology
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.When adopting biological method to dispose of sewage, can produce a large amount of residue organic sludges, the mud that these organic contents are very high must in time obtain treatment and disposal, otherwise can cause secondary pollution, and the final settling mode of mud mainly adopts: landfill, agricultural, drying and incineration.Due to industrial development, the heavy metal content most cases in mud all exceeds standard, can't directly carry out agriculturally, and simultaneously due to constantly the dwindling of landfill yard area, the mud shipment distance is more and more remoter again.Though and mud is through processed, its water ratio is still higher, causes landfill yard to be difficult to accept, so cause can't landfill or the landfill expense constantly rise.Traditional method for sludge treatment namely carries out simply mechanicalness and concentrates and processed in sewage work, can not satisfy processing requirements and the cleanup standard of present stage.
The composition of sewage sludge is very complicated, except containing a large amount of moisture, also contains a large amount of useful resources, and the mud through after mummification can apply to land reclamation, building materials utilization etc.The sludge drying mode has: natural air drying, direct heating and indirect heating.How to reduce the water ratio of mud, reduce energy consumption, this is the gordian technique of sludge treatment.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, and a kind of sludge drying belt filter press is provided, and can further reduce moisture percentage in sewage sludge, has the direct mummification of middle temperature, the characteristics that level of automation is high.
The purpose of this utility model is achieved through the following technical solutions: a kind of sludge drying belt filter press, be comprised of belt filter press and desiccation machine, it is characterized in that: described belt filter press is made of pressure filter rack, pressure filter drive-motor, upper strainer, tightening device, filtrate collection pipe and lower filter belt; Described desiccation machine is made of lower conveying belt, desiccation machine frame, conveying belt drive-motor, collecting hood and upper conveyor belt.
Medicine mixing device is installed in described belt filter press upper end.
Described conveying belt drive-motor connects upper conveyor belt and lower conveying belt with transmission chain.
Further, described lower conveying belt mud outlet end is provided with the dewatered sludge receiving tank, and the dewatered sludge receiving tank connects worm conveyor.
The utility model principle of work: after sewage work's settling tank mud tentatively concentrates, be 98%~99% mud suction medicine mixing device with water ratio with sludge pump, add the flocculation medicament in medicine mixing device, sludge flocculation enters belt filter press after becoming particle, mud and filtrate are at upper strainer sharp separation, mud is strainer and the further press filtration of lower filter belt contact part on entering, and water ratio drops to 80%~85%.mud after press filtration further reduces water ratio in sludge drying machine, hot blast enters sludge drying machine from the hot blast import, the conveying belt drive-motor drives lower conveying belt and upper conveyor belt rotates, mud flows on two conveying belt, hot blast sees through successively lower conveying belt and upper conveyor belt and takes away water vapor, water ratio drops to 45%~55%, after mummification, mud is collected at the dewatered sludge receiving tank, then mud transfers out from worm conveyor, the hot blast that contains moisture is collected in collecting hood, discharge from hot-blast outlet, the part waste gas circulation is got back to the hot blast import, contain moisture waste gas through condensation and process up to standard after discharging.
In sum, the beneficial effects of the utility model are: directly mummification of temperature in employing, and direct heating, the heat transfer area of mud conveying belt is large, can make general moisture percentage in sewage sludge be about 98%~99% and be reduced to 45%~55% left and right, has obviously reduced the water content of mud; And be furnished with air circulation system, take away rapidly the moisture of mud evaporation; Sludge drying and belt filter press can automatic operatings, and be easy to operate; The utility model adopts totally-enclosed system, has reduced the secondary pollution of mud, can arrive the requirement of recycling.
