Dear sea friends! Does anyone know anything about vertical furnaces! Tell me!

Main production facilities: coal preparation workshop, carbonization workshop, coking screening workshop, gas purification workshop (including desulfurization section), and sewage incineration workshop. Coal preparation workshop: The raw coal is delivered to the coal receiving pit using a dump truck, and then unloaded onto a belt conveyor which transports it to the screening building. After screening, the coal particles with a size of 25–80 mm are sent, via belt conveyors and transfer stations, to the storage bin in the vertical furnace’s top coal tower. Carbonization workshop: The lump coal in the furnace top coal bin is fed into the carbonization chamber via an auxiliary coal bin. The lump coal fed into the carbonization chamber moves from top to bottom, coming into countercurrent contact with the high-temperature gases in the middle of the chamber, and is carbonized into semi-coke ; The semi-coke is cooled in the cooling section at the bottom of the carbonization chamber; thereafter, it is pushed from the pusher plate into the quenching tank using a reciprocating coke pusher. After being continuously discharged by a scraper coke discharger, it falls onto the dryer through chutes. Furnace structure and features: 1) Compared with ordinary vertical carbonization furnaces, this type of furnace has an increased internal volume. Thus, it provides favorable conditions for the stable and high-yield production of vertical carbonization furnaces. 2) The volume of the combustion chamber was increased, and the number of air inlets was appropriately raised, allowing gas and air to burn fully within the combustion chamber; the hot exhaust gases then enter the carbonization chamber evenly, thereby effectively preventing slag formation and erosion at the air inlets. 3) On each side of each carbonization chamber, there are two layers in total – upper and lower – giving rise to 4 independent horizontal flue channels (combustion chambers), which allow for flexible adjustment of the temperature distribution within each carbonization chamber, thereby ensuring uniform and stable quality of the products produced by the entire furnace. Coke screening workshop: The semi-coke discharged from the carbonization furnace enters a dryer, and then passes through a conveyor belt; it is screened using multiple layers of vibrating screens, and the coke at different particle sizes is sent to the coke storage area via conveyor belts. Gas purification workshop: The gas purification workshop is divided into a drum cooling section and a desulfurization section. The process for the drum cooling section is shown in Figure 4. The raw gas emerging from the top of the carbonization furnace passes through a gas collection tank, a gas-liquid separator, and a direct cooling tower (consisting of a direct cooler and an intercooler) to be cooled; during this process, coal tar is recovered. The gas is then sent, in part, to an upright furnace via a gas blower for heating. The remaining gas is desulfurized in a desulfurization unit before being sent to a wastewater incineration plant for the incineration of industrial wastewater, as well as for sale (for power generation, burning limestone, producing magnesium metal, etc.). Desulfurization section. The gas from the drum cooling section enters the lower part of the desulfurization tower, where it comes into countercurrent contact with the desulfurization liquid sprayed from the top of the tower in order to absorb hydrogen sulfide from the gas. The gas then passes through the mist removal section to have any mist droplets removed, before being sent to the gas holder. After desulfurization, the hydrogen sulfide content in the gas is no more than 200 mg/m3. Wastewater incineration workshop: The produced wastewater is treated using the invention patent from the China Iron and Steel Research Institute, namely the \"Coking wastewater incineration treatment technology using gas as a heat source\". Achieve zero discharge of industrial wastewater.

Reply to 2#: I’m awesome! Could someone send over the structural diagram or assembly diagram of the vertical furnace so that everyone can learn from it?*

I’m sorry, structural diagrams or assembly drawings cost money and are not easy to obtain.

The last edit to this post was made by liu*anzhe12 on 2010-6-1 at 10:23. Reply to 4#: I’m great, haha. I understand; I’m not expecting a complete version either. I just hope to get a basic understanding of the overall structure. For my graduation project, I need to create a diagram of the equipment, and it’s really difficult to draw something from scratch :L :funk: :L. Or if anyone who knows about this can explain it in words, that would also work
