The working routine of star wheel sludge drying tower:
1) mud that will wet is inputted dosing unit by raw material conveying device, dosing unit is spread in wet mud above the first floor star-wheel dry component of the dry assembly of star-wheel throttling uniformly, air compressor machine or Hydraulic Station fluid-pressure system start by set date star-wheel drive assembly, star-wheel drives assembly utilization to connect the hinged disc crank of rope can make each star-wheel mechanism reciprocally swinging respectively, when the star-wheel upset of star-wheel mechanism, mud is dispensed onto on lower one deck star-wheel dry component; Natural wind enters between interior each layer of star-wheel dry component of kiln or in the gap between star-wheel mechanism and mud, the moisture heat exchange in natural wind and wet mud, takes away the moisture that this mud is evaporated; By that analogy, the dewatered sludge that mud becomes water ratio to be less than 30% after every layer of star-wheel dry component of the dry assembly of star-wheel throttling is dry, dewatered sludge enters in dry slag delivery assembly; At the water ratio of wet mud that enters dosing unit, lower than 55% time, dewatered sludge is input to dry mud and stores; If at the water ratio of wet mud that enters dosing unit higher than 72 o'clock, wherein a part is transported in dry slag back-mixing device and mixes with the wet mud that enters dry slag back-mixing device, avoid mud to occur " gluing phase ", be input to auxiliary wet drying sludge in dosing unit, another part is input to dry mud and stores field in order to recycling again; When natural wind speed is less than 0.5 meter per second, gas blower enters kiln by high wind by air inlet duct, adjusting air quantity and breather hole baffle plate;
2) when local wind speed is greater than 5 meter per second, stop blower fan;
3) when being less than 0 ℃ when ground temperature, the blade of Universal wind wheel is turned back and wraps up dosing unit and the dry assembly of star-wheel throttling, start air inlet system, the star-wheel mechanism blowing to kiln;
3) when being less than 0 ℃ when ground temperature, the blade of Universal wind wheel is turned back and wraps up dosing unit and the dry assembly of star-wheel throttling, start exhaust system, the air between the star-wheel mechanism of suction dried chamber;
4) when being less than 10 ℃ when ground temperature, by air inlet duct, input hot blast;
5) when mud generation foul odour, start exhaust system, induced draft fan is transported to kiln air after odor removal is processed and discharges;
6), while needing the further reduction of moisture percentage in sewage sludge or fast reducing to 10% following, utilize the base plate of flat-bottom bin to pass into hot fluid medium; Start air inlet system, by air inlet duct, input hot blast;
7) when leeward to the air velocity in certain region of kiln when lower, can be by regulating the independent air feed of distributing air damper;
8) at kiln entrance, go out to arrange material sensor, when solid accumulation is higher, stop feed.
When back-mixing, trommel screen is picked out relatively large dry tabular mud cake, and recycling measuring apparatus scatters it on taper pinnacle of a pagoda that wet mud in taper pinnacle of a pagoda or balladeur train pusher top of the dry assembly of star-wheel dispensing piles up by raw material conveying device with suitable flow.
When adopting the dry assembly of star-wheel dispensing, can by connecting rod, drive separately with fluid driven cylinder the star-wheel mechanism of windward side and upper and lower a string star-wheel dry component that show up day of the dry assembly of star-wheel dispensing with speed reciprocating swing faster; With fluid driven cylinder, by connecting rod, drive the star-wheel mechanism of the core of upper and lower a few string and several groups of dry assemblies of star-wheel dispensing.
Windward side, day that show up by the motorized valve of pressure fluid system, control respectively with the speed of star-wheel mechanism reciprocating swing core, make velocity of evaporation faster material with speed faster, move down.Embodiment is shown in system and the technical process of the work of supporting star wheel sludge drying tower, by PLC sequence control system, can go round and begin again and automatically perform above-mentioned mummification working routine.
The mud stench concentration that is in operation wetter is larger, utilizes the odor removal that the ducting outlet of the induced draft fan of drying air stream assembly adds to address this problem; At natural energy resources, can not meet mummification requirement, utilization adds airheater and can well address this problem before the entrance of the air channel of drying air stream assembly.
The mud of sewage work general organic matter after over dry accounts for 50% left and right, and mud solid content is 35%～45% time, and calorific value is 4.8～6.5MJ/kg, can self-sustaining burning, conventionally directly connect burning process below.Dewatered sludge can be used as soil improvement agent, fertilizer, rubbish overburden soil, or during as cement kiln, power station and incinerator fuel, mud solid content is increased to 80%～95%, if utilize the cost that this equipment can be very low that mud solid content is increased to 90%, be equivalent to 50% of standard coal as its calorific value of fuel.Because mud in squeezing in early stage does not add any flocculating aids except polymeric flocculant, iron(ic) chloride for example, in burning, greatly reduced the pollution to the corrosion of equipment and atmospheric environment, fuel as the higher forward calorific value of cost performance is well received, existing market price can reach 60 yuan～80 yuan/ton, this price can support mud utilize this equipment by water ratio from the 60% large portion expense of being down to 10% drying and other treatment.
Rule of thumb, the moisture steam capability of mud exposed surface is 75% of local free-water level steam output, take Beichen District, Tianjin as example, and average annual free-water level steam output is 1777.7 millimeters.Account for 37% spring; Account for 35% summer; Account for 19% autumn; Account for 9% winter.Year sunshine time 2470～2900 hours, annual the longest with sunshine in May, total radiation is also maximum.In 1 year, 7,8 monthly mean relative humidities are maximum, can reach 80% left and right.Tianjin annual mean wind speed is 1.9～4.3 meter per seconds, and owing to affected by monsoon, wind is obvious with seasonal variation.Winter northwest wind prevailing, spring many southwester, summer southeaster prevailing, autumn variable direction.Year, maximum wind directions were southwester.In 1 year, Windy Days is maximum spring, and mean wind speed is maximum, and take second place winter, and summer, mean wind speed was minimum.With the annual zero carbon input of this this equipment of data, can reach 200～280 days working time, the effect of energy-saving and emission-reduction is remarkable.If 1-2 month mud storage facilities is set in technique, at atrocious weather, store mud raw material, just can realize the sludge drying of annual input mud zero-carbon heat sources and process.
In this equipment, only star-wheel mechanism makes the standing evaporation area maximum of mud of every cubic metre of kiln volume reach 11.6M2, the space of causing due to wet mud contraction distortion makes again the evaporation area of material be multiplied, kiln material peak filling rate can reach more than 50%, according to moisture steam capability in experiment mud, is 75% of free-water level steam output.In the actual use of Efficiency in Buildings in Tianjin Area April, every square metre of mud evaporation area steam output be 2kg/d, the wet mud of water ratio 60% is dry by this equipment, do not need dewatered sludge back-mixing, envrionment temperature is 22 ℃ by day, relative humidity 70%, normal sunshine, mean wind speed 2 meter per seconds, mud is down to 25% with four days water ratio, and more natural mummification is raised the efficiency more than 8～10 times.The specific investment cost of this equipment is lower than 1.5 ten thousand yuan/ton the mud of water ratio 80% (press conversion), with the specific investment cost that early stage, squeezing system added up to lower than 3.5 ten thousand yuan/ton (mud of water ratio 80%).Process the specific investment cost of the existing sludge drying technique of identical material, for example spray dried turns to 100,000 yuan/ton, generating multifuel combustion is 80,000 yuan/ton, biological dewatered is 100,000 yuan/ton, and other comprehensive anhydration system is 10～250,000 yuan/ton, apparent, the sludge drying technique that compares other, native system energy-saving and emission-reduction, reduce to process with the running cost of disposing and reduce, and investment reduces, effect is remarkable.
This equipment is having wind, or does not need to input separately petrochemical industry heat energy while using under sunlight, and operation priming cost is mainly the expense that star-wheel mechanism drives, and cost is very cheap.Because winter temperature is lower, mud can be preserved at low temperatures, be more conducive to drying treatment the season taking a turn for the better at temperature by freezing treatment, recommend the ability of wet mud storage field below 2～March.If must use this equipment in the winter time, adoptable mineralising thermal source is the useless flue gas of power plant or hotblast stove warm braw.
The disposable energy of tellurian mineralising is the non-renewable resource of finite sum, and existing sludge drying technique often all needs to expend a large amount of precious resources, if take low-carbon technology by mud fuel made, and fuel value is greater than or equal to cost of manufacture, to be that merit is being worked as generation, the contribution of profit is in the future thousands of years.Utilize wind energy and sun power to make us approach this target as the zero-carbon heat sources of dehumidification system, even if the production time is slightly longer and historical long river is compared also extremely of short duration.
