Description

The cold dry conveying device of dregs of incinerator
Technical field
The present invention relates to a kind of improvement of hazardous Waste Incineration auxiliary equipment, and in particular to a kind of dregs of incinerator is cold dry Conveying device.
Background technology
In the incineration disposal of China's industry dangerous waste and clinical waste (being collectively referred to as dangerous waste), it can produce and burn total amount about 15% Clinker, it is about 40,000,000 tons that current domestic year, which burns dangerous waste amount, and year produces about 6,000,000 tons of clinker, due to being belonged to together on slag properties In dangerous waste, so clinker need to carry out solidification landfill.Traditional cooling of furnace slag mode, when it is air-cooled, second, water seal cools down.It is air-cooled Shortcoming is a lot, and first is cool time length, and cooling effectiveness is low so that solid accumulation is unable to timely processing;Second be it is air-cooled can not The central temperature of clinker is cooled down, do not reach cooling purpose;3rd is the air-cooled steam for being exposed in air, evaporating formation There are a large amount of VOC classes, form secondary atmosphere pollution.
Water seal cools down, and refers to allow clinker to fall in the cold rinse bank of closing, and water directly contacts carry out heat exchange, and it is maximum The shortcomings that one be to produce a large amount of contaminant waters, form secondarily polluted water;Two are so that more dry clinker itself, by into water It is honored as a queen water suction, the weight of increase about 30% so that clinker increase solidification about 600 yuan of cost of landfill per ton, the whole nation is added to every year This about 3.6 hundred million yuan.Apparatus of the present invention, cooled down by indirect type closed, effectively prevent the secondary pollution of National People's Congress's gas and water, it is cold But efficiency greatly promotes, and has significantly saved people and has solidified landfill cost.
The content of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of cold dry conveying dress of dregs of incinerator Put, it is prevented, and dregs of incinerator cooling effectiveness is low, cooling procedure produces secondary pollution, and it is defeated to provide a kind of roller jacket type cooling Device is sent, can there is effective temperature-reducing and loss of weight, its process is arranged without pollution is outer completely.
To achieve the above object, the present invention is using following technical scheme:It includes feed arrangement 1, drawing mechanism 2, bottom Seat 3, motor 4, support roller 5, roller 6, rolling ring 7, chain 8, sprocket wheel 9, roller 6 is double-layer barrel, and the left end of roller 6 is provided with Feed arrangement 1, the right side of roller 6 are provided with drawing mechanism 2, and roller 6 is arranged on support roller 5 entirely through rolling ring 7 and can held in the palm Being rotated on wheel 5, support roller 5 supports on the base 3, and the side of roller 6 is provided with motor 4, and sprocket wheel 9 is being provided with roller 6, Motor 4 connects sprocket wheel 9 by chain 8.
Clinker caused by rotary kiln 12 or grate furnace afterbody in the present invention, after screen pack 1-1 filterings, then from charging Device 1 enters roller 6, and now motor 4 is started working, and roller 6 starts to rotate, and is sufficiently mixed and stirs material so that thing Expect uniform decrease in temperature;Because roller 6 itself carries the gradient, so material can move forward with the rotation of roller 6, in order to anti- Only material movement is too fast, is additionally arranged weir plate 6-1 and is slowed down.
The cooling medium of whole process is soft water or demineralized water, all the time the water leg between the double-deck barrel of roller 6, soft Circulated between hydrophone, cooling tower.
The present invention has the following advantages compared with prior art:System is reasonable, good cooling results;Easy to maintenance, cost is low;By In the aforesaid drawbacks for avoiding traditional air-cooled and water cooling, so having preferable technical advance and economic benefit.
The cold dry conveying device of clinker of the present invention, has the following advantages that:1st, ash temperature caused by rotary kiln/grate furnace can Up to 800 DEG C, high temperature furnace slag effectively can be down to 50-60 DEG C using the system;2nd, cool time is short, and cooling procedure was on 20 minutes left sides It is right;3rd, cooling medium is softened water or demineralized water, and wide material sources, cost is cheap, and is recycled;4th, relative to water before Envelope cooling, the moisture content for clinker of slagging tap are down to 3% from 35% before, significantly reduce the solidification landfill cost of clinker;5th, it is defeated The material diameter sent reaches as high as 250mm;6th, system that employs the conveying principle of rotary kiln form, system is made to form an independent envelope The circulation closed, avoid producing heat radiation to surrounding environment;7th, relative to the former water seal type of cooling of slagging tap, clinker is not only caused Moisture content reduce more than 90%, significantly reduce solidification landfill cost of the clinker as dangerous waste, and effectively prevent clinker Substantial amounts of contaminant water caused by directly being contacted with water seal water, beneficial to environmental protection.
