Description
The present invention relates to improve the solid materials grade.
Particularly, but be not only to the present invention relates to improve the grade of solid materials with lower thermal conductivity.
More particularly, thus the present invention relates to improve the method for solid materials grade by removing moisture content in the material.This method comprises: solid materials is heated to high temperature, protects high pressure simultaneously, the material that will improve grade then is cooled to room temperature.
Of the present invention one special use be improve carbonaceous material (being generally coal) thus grade increase its BTU value.
The United States Patent (USP) 5290523 of Koppelman discloses the method that a kind of while application of temperature and pressure improve the grade of coal.
Koppelman discloses the method that heat is sloughed water from coal: heating coal changes its physicals under High Temperature High Pressure, thereby acts on from coal except that anhydrating through " squeezing ".
It mainly is liquid rather than water vapor that Koppelman also openly keeps sufficiently high pressure to make the water byproduct of generation in the method.
Koppelman also discloses the selection of carrying out a series of different devices of this method.
Usually, select based in pressurized vessel, heating coal.Pressurized vessel comprises the inlet of back taper, columniform container body, conical outlet and is arranged in the heat exchanger tube assembly of the horizontal or vertical installation of container body.
In a kind of scheme, the pipe and the exit end of vertical distribution are filled with coal, inject nitrogen and make pipe and exit end precharge.Oil is carried out indirect heat exchange as heat exchange fluid supply-pipe exterior circular column heats coal.Direct heat exchange by coal and water vapor (as the working fluid in the packed bed) further heats.In addition, water vapor makes pipe and exit end be forced into required pressure.
Combination in pipe and exit end high temperature and high pressure condition can evaporate some water from coal, be condensed into liquid then.Because high pressure adds a part of water vapor that produces after the entry and also is condensed into liquid in colder zone.Be not condensed, packed bed reaches the required excessive water steam of best precharge and must extract out.Produced uncondensable gas in addition (as CO, CO
2), also need to extract out.Periodically from outlet leachate body.
At last, after through the predetermined residence time, thereby the container decompression through exit end with the raising of heat the coal of grade be expelled to conveyor and coal is transferred to wet type advances feeder (wet auger).When conveyor is transferred to coal wet type propelling feeder, water has been sprayed onto hot raising on the coal of grade.Coal further cools off in wet type propelling feeder, is paved into thin layer in the storing district then and is cooled to room temperature.
