The depth of material purifies and taste removal.Operation and the combustion case of carbon materials are monitored by upper observation hole 21 and lower observation hole 31.
(3) after the completion of roasting, carbon materials enter lower furnace body 3 from combustion chamber 4, burn with stopping after oxygen-barrier.Pass through
Cooling jacket 7 cools down carbon materials, its temperature is made to be down to 300 DEG C or less.Carbon materials after cooling are from 3 bottom of lower furnace body
End sequentially enters conveying body 8 and cylinder round sifter structure 9, and the ash content and carbon materials powder that burning is generated are from block
Separation obtains clean carbon materials finished product after finally carrying out cooling again with pure water vapour.
The whole design of the device has the following advantages that：Building specification can be zoomed in or out on year-on-year basis, and scale becomes
Change flexible；It designs production capacity and variation production capacity adjustable proportion is big；Capital investment is few, and it is low to build difficulty；The mechanization of production process,
High degree of automation, failure rate is low, and plant maintenance is easy with maintenance, the expense of generation is low；Equipment energy consumption is low, and the environment of generation is dirty
Contaminate object it is few, run smoothly, manipulate it is easy to learn；The labor operation personnel for needing to be equipped with are few；To the applicable model of raw materials for production specification
It encloses wide；The recovery utilization rates such as the waste heat, the combustible gas that generate in production process are high；Finished product output capacity is high, and loss rate of raw materials is low.
Using the device of the invention, roasting purification is carried out to same a batch of semi-coke of Shenmu County's production and taste removal is handled,
The performance parameter variations of semi-coke are as shown in table 1：
Table 1
As known from Table 1, calcination process is carried out to semi-coke using the device of the invention, specific surface area and the hole of semi-coke can be made
Gap rate increases, and density reduces, and makes being readily burned for semi-coke change.The solids such as remaining coal tar, sulphur, nitrogen, ammonia in semi-coke simultaneously
Matter under high temperature environment through oxygen-enriched air roasting, gasification, volatilize away from hole, content is reduced within 0.2%, when lighting without
Cigarette is tasteless.Simultaneously as roasting eliminates the interior water (crystallization water) and outer water (Natural Water) of semi-coke, so that fuel value is in certain journey
It is improved on degree.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
