Device for performing cyclic condensation on water for production of graphite

Abstract

The invention discloses a device for performing cyclic condensation on water for production of graphite. The device comprises a settling pond, an air flotation pond, a primary recovering pond, a cleanwater pond and a spraying pump; the settling pond is connected with a liquid outlet pipe; the water inlet end of the liquid outlet pipe is connected with the liquid outlet of a spraying tower; a medicament tank for adding a flocculating agent into the settling pond is arranged on one side of the settling pond; the first outlet of the settling pond is communicated with the primary recovering pond;the second outlet of the settling pond is communicated with the air flotation pond; the first outlet of the air flotation pond is communicated with the primary recovering pond; the second outlet of the air flotation pond is communicated with the clean water pond; the water inlet of the spraying pump is communicated with the clean water pond; and the outlet of the spraying pump is communicated with the spraying tower through a liquid spraying pipe. The device for performing cyclic condensation on water for production of graphite has the advantages of good water treatment effect, large water treatment quality and capabilities of recycling water resources and saving water resources.

Description

technical field [0001] The invention relates to the technical field of graphite production, in particular to a graphite production water circulation condensing device. Background technique [0002] Needle coke is the main raw material for producing high-power (HP) and ultra-high-power (UHP) graphite electrodes, and it can be divided into petroleum-based needle coke and coal-based needle coke. Due to the good graphitization performance of needle coke, the HP and UHP graphite electrodes produced by it have excellent electrical and thermal conductivity, thermal shock resistance and oxidation resistance, which can meet the requirements of high current density in large-capacity electric arc furnaces and rapid cooling. In the rapid heating state, there are high mechanical strength and other smelting quality requirements, which are incomparable in terms of performance of graphite electrodes produced by ordinary coke. [0003] In the process of producing graphite with needle coke, ...

Problems solved by technology

[0003] In the process of producing graphite with needle coke, high-temperature sintering is an essential and important process, because the material composition in needle coke is extremely complex, so the composition of tail gas after high-temperature sintering is complex, containing a large amount of harmful gases and gaseous For oily substances, such as sulfide gas and gaseous asphalt, our company has developed an aqueous solution condensation device, which can condense the high-temperature gas in the tail gas and make the water-soluble sulfide dissolve in water, but this condensation device consumes a lot of water , in order to reduce the consumption of water resources, the company has developed a graphite production water circulation condensing device
