Description
Technical field
The present invention relates to a kind of drying sludge deodorization transportation integration apparatus, belongs to sludge drying, deodorization, conveying technology neck
Domain.
Background technology
The yield of municipal sludge is huge and complicated component, how municipal sludge is disposed with using turning into people
The problem of of interest.The processing disposal of sludge should be with " minimizing, stabilisation, innoxious " for final purpose.Sludge drying is made
Carry out the processing method of deep dehydration to sludge with industrial equipment for application artificial heat, its operation temperature is typically larger than 100
DEG C, the Treatment Effects to sludge are dried, are not only deep dehydration, the effect also with heat treatment；In addition, sludge drying is handled
Product, its moisture content can be controlled in less than 30%, can suppress the activity of microorganism in sludge, therefore sludge drying processing can be simultaneously
Change physics, chemistry and the biological nature of sludge, play and reduce sludge volume, stabilized sludge property, innoxious effect.
Sludge drying process is generally combined with using waste heat at present, such as rubbish and sludge incineration waste heat, waste heat of power plant
Or the thermal source that other waste heats are handled as sludge drying.Sludge after desiccation, which is generally gone through, to cool, and then passes through dewatered sludge
The equipment such as belt conveyor, dewatered sludge bucket elevator, are delivered in dewatered sludge storehouse and are stored, and pass through truck transport, belt afterwards
The modes such as conveyer conveying are delivered to coal bunker, and being delivered to incinerator by fuel delivery system after being mixed with coal is burned.It is whole
Individual sludge drying, course of conveying are very long, take place area broadness, and dewatered sludge storage time is grown, and fed distance is remote.In this mistake
Cheng Zhong, a large amount of foul smell are produced in on-site, stink spreads in place, and serious pollution destroys the building ring of field operator
Border.Easily fermented because dewatered sludge is stored in sludge bin, cold outside winter, interior heat, easy counter tide, blocking, usual dewatered sludge storage
Require that transport is gone out in 24 hours.Negative pressure is respectively provided with the way in sludge bin, conveying, is drawn foul smell with air-introduced machine, waste gas is sent
Burned toward incinerator, or be sent to Biological filter deodorization system and carry out qualified discharge after deodorization.Even if taking these measures, have
The place of sludge anhydration burning engineering project, is still a mass of foul smell everywhere, and having become restriction sludge anhydration burning engineering should
With a bottleneck problem of prospect, it is badly in need of solving.And buy, arrange largely draw smelly, deodorizing device, also increase enterprise fortune
Capable cost, the economic benefit of enterprise is had a strong impact on.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, offer one kind can realize sludge drying, deodorization, transport
The device of integration.
The purpose of the present invention is achieved by the following technical solution：

And thermal source 21 is delivered to, reheated, so as to realize recycling for steam (or water) or conduction oil.According to drying sludge
Technological requirement, a number of separate heating plate 14 is disposed below in not viscous formula crawler belt 13, so as to be sequentially formed
Some heating zones, the operation temperature of every section of heating zone can be adjusted.Cooling water is then by pump 22, respectively by cooling water by cooling water
Inlet tube 25 is delivered to the intracavitary for some separate coldplates 15 that some not viscous formula crawler belts 13 are disposed below, and is passed with contacting
The mode of heat is suitably cooled down the dried sludge that some not viscous formula crawler belts 13 pave above, dewatered sludge is obtained constant speed
Cooling；Cooling water after heating is returned by cooling water outlet pipe 26 and cooled down again again, so as to realize the circulation of cooling water
Utilize.
Caused tail gas (containing moisture and mud granule) in drying sludge deodorization conveying body casing 12, by being arranged in shell
The offgas duct 27 on the top of body 12 is drawn, and the tail gas of extraction enters cyclone dust collectors 28 and carries out dedusting, the mud granule being collected into by
Cyclone dust collectors 28 are dropped down onto in Blowing stopper 29 under bottom, and Blowing stopper 29 plays a part of sealing, prevent the bottom of cyclone dust collectors 28
Air is sucked, and continuously and uniformly the conveying of refeed line 30 downwards, the mud granule of collection finally return to dirt by refeed line 30
Mud dries the discharge nozzle 17 of deodorization conveying body, and dewatered sludge belt conveyor or dewatered sludge are sent to together with dried dewatered sludge
Storehouse.Isolate the tail gas after larger mud granule to be drawn by the central tube on the top of cyclone dust collectors 28, carried out into condenser 31
Condensation；Circulation is passed through cooling water in condenser, and the tail gas entered in condenser is condensed, and condensed condensation waste water passes through
Sewage disposal carries out reuse；Incoagulable waste gas is drawn by air-introduced machine 32 and is sent into sludge incinerator and burned.
