The co-processing mechanical material ejecting device mainly comprises a material releasing device, a material ejecting device and a material receiving device. The co-processing mechanical material ejecting device has the advantages that materials can be effectively prevented from being in contact with the external after the materials are packaged and then are fed into an exhaust smoke chamber of the cement kiln by means of ejection, so that pollution risks can be reduced; the materials are not easy to scatter in pipelines after being packaged and can be ejected and pushed easily; requirements of a co-processing mechanical material ejecting feeding method for the cement kiln on characters of the materials are low owing to the fact that the materials are packaged and then are fed into the exhaust smoke chamber of the cement kiln by means of ejection, and dioxin can be effectively prevented after the materials are ejected into the exhaust smoke chamber of the cement kiln no matter whether the materials contain volatile organic compounds or not.
Description
Technical field
Invention belongs to the hazardous waste processing technology field in field of environment protection, is specially in cement kiln synergic processing a kind of mechanical ejection material device and mechanical ejection material thereof and enters kiln method.
Background technology
Utilize cement kiln synergic processing solid waste to cause people's concern and attention, as far back as nineteen seventies, the developed country such as the U.S., Canada has just started to adopt cement kiln disposal of solid refuse, the nineties, Germany has just built 4500 tons of clinker cement kiln production lines of daily output, and the technology of cooperative disposal hazardous waste is ripe.And China just starts to utilize cement kiln to dispose the research of hazardous waste from the nineties in 20th century.
The basic principle of utilizing cement kiln disposal of solid refuse is worst hot case and the alkaline environment making full use of in cement kiln, makes thus this disposal options compare the superiority that other disposal options have six aspects:
(1) the temperature of charge in cement kiln is at 1450 ℃ to 1550 ℃, even higher, and under hot environment, the poisonous and harmful composition in solid waste is thoroughly decomposed, and the rate of destroying by fire can reach 99.99%.
(2) cement kiln thermal capacity is large, has stable combustion system, when disposing a large amount of solid waste, still can maintain even, stable combustion atmosphere.
(3) because cement kiln tube body is long, solid waste is under cement kiln high-temperature state, and the time of staying is long, burns fully, is conducive to burning and the decomposition of rubbish.
(4) in cement kiln, be alkaline gas, the sour gas physical efficiency that discharges of burning is played to neutralization, avoid the generation of bioxin after burning disposal.
(5) utilizing cement kiln disposal of solid refuse is unique mode that does not have waste residue to discharge in various solid waste disposal modes, and the combustible constituent in solid waste is as fuel, and non-combustible part can be used as raw material.
(6) utilize cement kiln disposal of solid refuse can not bring impact to cement product quality and production process.
And the key of cement kiln synergic processing is that material enters the selection of kiln mode, now mainly enters kiln mode and have from raw material section, to add together with cement raw material and enter, will material grinds, by Pneumatic conveyer, spray into etc.But this several method is all higher for the character requirement of material itself, even need to do certain pretreatment and just can add into kiln, to cement kiln synergic processing, bring certain constraint.
Said method can be suitable for common material, but larger for toxicity, endangers heavier material and is difficult to be suitable for, therefore find a kind of convenience, safety, simply can be suitable for high-risk material to enter kiln mode very important for cement kiln synergic processing.
