Description
Technical field
It is a kind of can be suitably used for aniseed semi-coke it is dry put out and UTILIZATION OF VESIDUAL HEAT IN device, be mainly used in the big of low temperature distillation side stove production
The closed cooling and waste heat recovery of material semi-coke, belongs to semi-coke process equipment field.
Background technology
At present, most enterprises produce semi-coke using low temperature distillation side's stove, and the red-hot semi-coke discharged from drop-bottom is entered with water
Row cooling：The coke discharge box of carbonization kiln bottom gos deep in screw clamp, and semi-coke is dropped down onto on the burnt plate of support from coke discharge box, will by coke pushing plate
Semi-coke is pushed away falls bottom of gullet, and in bottom of gullet water extinguishing process is completed.Scrapper conveyor is by wet semi-coke from bottom of gullet scraping delivery to baking
In dry machine.In scrapper conveyor course of conveying, wet semi-coke is dried using gas-fired.Semi-coke moisture content after drying is about
15%～20%, also need to carry out secondary drying to semi-coke when calcium carbide is produced.There is problems with above-mentioned water-cooled quenching：（1）
At 550 DEG C or so, semi-coke sensible heat is all wasted semi-coke temperature from carbonization chamber release during coke wet quenching；（2）Semi-coke is met water Quench and is held
Fritter is easily fragmented into, semi-coke quality is reduced；（3）Produced semi-coke contains large quantity of moisture, limits the use of semi-coke, increased fortune
Defeated cost, the energy for needing consuming extra is dried to it；（4）Consume substantial amounts of water resource；（5）During coke wet quenching,
Red semi-coke is met water and produces a large amount of organic gas and steam, is directly discharged in the middle of air, pollutes environment.
ZL201010190133.1 discloses a kind of dry equipment for putting out semi-coke of vertical internally-heated hollow retort, burnt by support
Plate, sparge pipe/pushing ram, quenching vat, burying scraper, pressure-regulating valve, the first semi-coke storehouse, first switch, the second semi-coke storehouse,
Second switch, belt conveyor composition.Semi-coke heap both sides between coke discharging mouth and the burnt plate of support, respectively set a porous water pipe, spray
