Description
Technical field
The invention belongs to a kind of sludge treatment equipment, be specifically related to a kind of sludge high-pressure anhydration burning processing system.
Background technology
In recent years, country is with local more and more stricter to the requirement of sewage disposal plant effluent index, " 12 " period, the mud of municipal wastewater treatment plant refers to the discarded object of dispose of sewage produced solid-state, semisolid and liquid state, containing a large amount of organic matters, heavy metal and pathogenic bacteria and pathogen etc., do not add process discharge arbitrarily, can cause serious pollution to environment, the requirement total to Treatment of Sludge is stabilisation, innoxious and minimizing.
, to the technical policy of municipal sewage Environmental capacity and new urban wastewater treatment firm pollutant emission standard (GB18918-2002) of promulgating, there is clear and definite requirement in country to the sludge stabilization of municipal wastewater treatment plant and farmland utilization.But actual conditions are, the construction of sewage treatment plant often only notices that sewage disposal will reach discharge standard.In recent years, owing to there being dephosphorization denitrification requirement, develop out many biologic process for treating sewage, and to Treatment of Sludge and disposal, generally only carry dewatered sludge outward transport and comprehensive utilization in design, do not calculate its investment and regular expenses, this will certainly cause secondary pollution.Treatment plant builds more, and the secondary pollution of mud is also more extensive.Without the mud of stable process, because content of organics is high, very easily corrupt and produce stench, especially just the mud of sedimentation basin, containing a large amount of germ, parasitic ovum and virus, easily causes the propagation of infectious disease.
Summary of the invention
For solving the deficiency in above-mentioned technology, the object of the invention is to: provide a kind of sludge high-pressure anhydration burning processing system, what form Treatment of Sludge recycles environment, reaches innoxious, the minimizing of Treatment of Sludge, stabilisation and resource.
For solving its technical problem, the technical solution used in the present invention is:
Described sludge high-pressure anhydration burning processing system, comprise sludge storage pool, sludge conditioning tank, filter press, dryer and sludge incinerator, sludge conditioning tank connects filter press by high-pressure hydraulic pump, filter press sludge outlet is connected to mud bunker by conveyer, mud bunker correspondence is provided with conveying worm, conveying worm terminal connects material distributing machine, material distributing machine connects dryer entrance, dryer outlet is connected to mixer by conveyer, the corresponding sludge incinerator of mixer is arranged, sludge incinerator steam Transportation is to steam turbine generator and/or dryer, sludge incinerator correspondence arranges exhaust gas cleaner.
The process that use the present invention carries out Treatment of Sludge is as follows:
The conditioning of mud: mud delivers to Treatment of Sludge factory sludge storage pool through mud transport vehicle, sludge storage pool storage mud amount is 5--7 days, mud in storage pool utilizes driving grab bucket, send into sludge conditioning tank, mud in sludge conditioning tank and sludge conditioner uniformly mix, form alkaline environment, utilizing reaction to release heat makes mud temperature raise, reach sterilization, heavy metal-passivated object, simultaneously, conditioner destroys organic institutional framework in mud, interior water in mud is discharged, mud becomes easy dehydration, coordinate dilution water, mud is diluted to about 92%,
The dehydration of mud: mud is after conditioning, add dilution water, the water content produced is the mud of about 92%, filter press is utilized thoroughly to dewater to muddy water, the first-selected high pressure plate and frame filter press of filter press, moisture percentage in sewage sludge after dehydration, at about 60%-50%, is broken through " the viscose glue phase region " of mud at one stroke, is made follow-up drying process become more convenient, energy-conservation.
The mummification of mud: the mud after dehydration enters material distributing machine under the effect of conveying worm, quantitatively mud is sent into dryer via material distributing machine, dryer moisture percentage in sewage sludge is out less than 30%, and calorific value is greatly about about 1500 kilocalories, particle is very little, and mud granule temperature is higher.
The burning of mud: the mud after mummification and a small amount of combustion-supporting material stir in proportion, after reaching certain calorific value, directly deliver to incinerator to burn, the steam produced is transferred into dryer for sludge drying, reach the object recycled, after sludge incineration process, the pathogen in mud is utterly destroyed; Mud is after burning, and generally subtracting capacity is 80%-90%, can save a large amount of landfill place, residual steam can be used as waste heat and generates electricity, residue slag send brick field to use as building materials, and the tail gas that sludge incinerator produces is by discharge after exhaust gas cleaner purification, and combustion-supporting material can select coal dust.
Wherein, preferred version is:
The waste gas that described sludge conditioning tank and filter press produce sends into sludge incinerator by incinerator air blast, by sludge conditioning tank and filter press arrange the lower waste gas of water capacity, all send into sludge incinerator by incinerator air blast to burn, reach the object of Treatment of Sludge workshop ventilation ventilating deodoring.
Described filter press outlet of sewer is connected to cesspool, and cesspool is connected to sludge conditioning tank by water pump, and the sewage of filter press enters cesspool, and the water in cesspool enters sludge conditioning tank as dilution water by water pump, recycles.
Described sludge conditioning tank, mud bunker and dryer institute waste air are connected to Tower for purifying waste gas by air-introduced machine, sludge conditioning tank, mud bunker and dryer waste gas out, mud substrate concentration is comparatively large, humidity is higher, be not suitable for sending into incinerator to burn, devise deodorizing facility separately, waste gas is discharged after deodorizing.
Described exhaust gas cleaner comprises denitrification apparatus, dust arrester, air-introduced machine and desulfurizer, sludge incinerator produce tail gas adopt denitrating tower carry out denitration, and then dedusting, desulfurization, tail gas rear high altitude discharge up to standard.
Compared with prior art, the present invention has following beneficial effect:
What the present invention can form Treatment of Sludge recycles environment, reaches innoxious, the minimizing of Treatment of Sludge, stabilisation and resource; Consider multiple economy, the technical indicators such as the extensive character of mud, calorific value, flammable performance, economic performance, operating cost, in conjunction with existing sludge disposal technology and equipment, technology is carried out integrated, equipment is made to be more suitable for for Treatment of Sludge, meet the extensive characteristic of Treatment of Sludge, make sludge treatment technique have more operability, meet more and more stricter pollutant emission standard, improve local environment, there is good economic benefit and social benefit.
