Description
Technical field
The present invention relates to ceramsite preparation process technical fields, link in particular to a kind of main kiln of drying kiln-of high efficiency drying
Corollary equipment group.
Background technique
Haydite is exactly as its name suggests the particle of ceramic.The external appearance characteristic of haydite is largely rounded or oval-shaped ball,
But it is not round or ellipse sphere there are also imitative rubble haydite, and is in irregular rubble shape, surface is one layer hard
Shell, this layer of shell are in ceramic or enamel, there is water proof to protect gas effect, and assign haydite higher intensity.Lightness is pottery
In many excellent performances of grain the most important and it heavy sandstone can be replaced to prepare light aggregate concrete, light mortar
The main reason for.
A kind of haydite as disclosed in the Chinese invention patent application No. is CN201110241100.X and preparation method thereof,
In the preparation process of existing haydite, enters mixing machine after pug drying kiln drying and pelletizer is entered back into rotary kiln and burnt
System, the tail gas of rotary kiln are discharged or are recycled after processing, and drying kiln drying pug reaches certain dehydration requirement and needs to consume
A large amount of energy consumption, drying cost is higher, meanwhile, the tail gas treatment device heavy load of rotary kiln needs continually to overhaul and unload
Material, the manpower and material resources cost of cost also remain high.
Summary of the invention
In view of the above technical problems, the main kiln linkage corollary equipment group of the drying kiln-of high efficiency drying of the present invention is used for
Sintering process in ceramsite preparation process, and rotary kiln exhaust gas is passed through baking after preliminary dust removal directly or after secondary combustion chamber
Dry kiln improves the drying efficiency of drying kiln, has saved drying energy consumption, while also reducing the burden of rear cleaner, section
The human and material resources of exhaust-gas treatment is saved.
To achieve the above object, the main kiln linkage corollary equipment group of the drying kiln-of a kind of high efficiency drying designed by the present invention,
Include:
Single-revolution kiln, for being sintered to haydite materials;
One pre- cleaner, is connected with the offgas outlet of the rotary kiln, for carrying out preliminary dust removal to tail gas;
At least one drying kiln is connected with the tail gas after preliminary dust removal, for carrying out drying and dewatering to pug;
One deodorizing device is connected with the tail gas by the drying kiln, for carrying out deodorization to tail gas;
Cleaner after one is connected with the tail gas after deodorization, for the dust removal process before exhaust emissions or recycling.
The heat source (such as hot-blast stove) that drying kiln used herein does not carry, only one kiln body will be still in height
The tail gas of warm (200 ~ 300 DEG C) state is passed through drying kiln, is capable of providing heat source, the waste heat of rotary kiln is utilized, saved drying
Cost, at the same the pug in drying kiln with moisture also can the remaining dust of absorbed portion, alleviate the negative of rear cleaner
Load.
As a preferred embodiment of the above technical solution, the pre- cleaner by cyclone dust collectors and bag filter series connection and
At.
The dust removal mechanism of cyclone dust collectors is that dust-contained airflow is made to rotate, by means of centrifugal force by grit from air-flow
Wall is separated and be trapped in, then so that grit is fallen into ash bucket by gravity, as the cleaner for contacting tail gas first, energy
Enough most dust removals, disadvantage is lower to the removal efficiency of micron-level particle size fine dusts below;For this purpose, immediately
Collocation use bag filter, by filtering sieve mechanism the dust in dusty gas is removed, in general,
After cyclone dust collectors and bag filter processing, dust removal efficiency is generally 99% or more, and house outlet gas dust content is in number
Ten mg/m3Within.
As a preferred embodiment of the above technical solution, the drying kiln is the mud drying that drying and dewatering is carried out to riverway sludge
Kiln.
Riverway sludge itself contains large quantity of moisture, even if still remaining when entering in drying kiln after plate and frame filter press is handled
There are many moisture, this characteristic brings the effect of two aspects: 1. proposing higher want to the drying performance of drying kiln first
It asks, i.e. drying kiln needs to consume after more energy consumptions are dried or dried that moisture content is still higher, does not reach requirement, at this fashion
It is that drying kiln brings calorie source in the tail gas of high temperature, helps to promote the drying efficiency to riverway sludge, and saved drying
The energy consumption of kiln;2. the biggish pug of moisture content is easier to remaining dust in absorption tail gas, so that when tail gas passes through drying kiln in it
Dust removal rate promoted, and then alleviate it is subsequent after cleaner dedusting pressure and dedusting cost, dried through mud
After dry kiln absorption dedusting, the dust content in tail gas is further reduced.
As a preferred embodiment of the above technical solution, the deodorizing device is ozone deodorizing apparatus.
Ozone deodorizing apparatus irradiates foul gas using special high energy ozone and UV ultraviolet beam, cracks foul gas
Such as: ammonia, trimethylamine, hydrogen sulfide, first sulphur hydrogen, methyl mercaptan, methyl sulfide, methyl disulfide, carbon disulfide and styrene, sulfide H2S,
VOC class, the molecular link of benzene,toluene,xylene etc. make to be combined into small molecule in the contaminant molecule and ozone oxidation of free state
The compound of harmless or low evil, such as CO2、H2O etc..
As a preferred embodiment of the above technical solution, the rear cleaner is screen collector.
Screen collector belongs to a kind of cleaning equipment of wet type, is adequately collided with dust using water flow, utilizes water
Particulate matter and water mixing in pearl and dust, so that the dust particles of clean gas discharge and water reaction after being cleaned
Also it will directly stay in deduster and precipitate, the later period is cleared up.
As a preferred embodiment of the above technical solution, the water in the screen collector after dedusting is passed into vent gas treatment circulation
It is settled in pond, the upper layer clear water of the vent gas treatment circulatory pool is returned to reuse in the screen collector, lower layer's sedimentation
Object recycling is spare.
Lower layer's sediment can be delivered to by sludge pump at plate and frame filter press be dehydrated it is spare, can still do haydite materials.
After drying kiln or the absorption of mud drying kiln, the dredging period for the vent gas treatment circulatory pool that screen collector is connected
It is obviously prolonged, reduces the frequency of dredging, saved dredging cost.
As a preferred embodiment of the above technical solution, further include a secondary combustion chamber, be sintered for being undertaken in the rotary kiln
Haydite, tail gas after preliminary dust removal flows to drying after heat exchange by the secondary combustion chamber and sintered haydite again
Kiln, deodorizing device and rear cleaner.
After kiln tail tail gas is introduced secondary combustion chamber, exhaust temperature can be promoted to 400 ~ 500 degree, enter back into drying kiln just
It is to be directly entered drying kiln than former kiln tail tail gas to improve thermal energy, also improves the thermal efficiency.
Compared with prior art, the present invention have the following advantages that and the utility model has the advantages that
The main kiln linkage corollary equipment group of the drying kiln-of high efficiency drying of the present invention is for the agglomerant in ceramsite preparation process
Sequence, and rotary kiln exhaust gas is passed directly into drying kiln after preliminary dust removal, it is especially suitable for being passed through in the drying kiln of riverway sludge;
It improves the drying efficiency of drying kiln, pug can be made to reach the index of moisture content under the premise of less energy consumption, together
When also reduce the burden of rear cleaner, save the human and material resources of exhaust-gas treatment.
