Description
Technical field
The present invention relates to the technical fields more particularly to rotary semicoke heat of the cooling of dry distillation of coal semicoke and heat recovery to return
Receiving method.
Background technique
Important one of product is exactly semicoke in the dry distillation of coal, and semicoke is a kind of important industrial chemicals and clean fuel,
Purposes and its extensively.The semicoke temperature generated after the low order dry distillation of coal is at 500 ~ 700 DEG C, it is therefore desirable to cooling quenching.General quenching
There are two types of methods, first is that wet quenching, i.e., directly contact semicoke with water, to achieve the purpose that cooling；This method is simple and easy, but
Water consumption is big, and cooling procedure can generate a large amount of vapor, and carry a large amount of phenols, cyanide, sulfide and dust secretly etc.
Harmful substance adversely affects post-processing, and discharging directly into atmosphere then pollutes the environment, and forms bigger harm.Second is that Dry Quenching,
Cooling is contacted with high-temperature semi-coke by cold inert gas, heat is taken away by carrier gas, or is set by dedicated cooling
It is standby, using the mediate contact of cooling water and high-temperature semi-coke, achieve the purpose that cooling；Dry Quenching can overcome wet quenching to pollute
The shortcomings that environment, but special cooling equipment is needed, and invest also larger.
