Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of sewage treatment, and particularly relates to a phenolic water recycling device. BACKGROUND

[0002] Phenolic wastewater refers to industrial wastewater containing phenolic compounds, mainly from petroleum refining, coking, chemical, pharmaceutical, pesticide, dye and other production processes; among them, phenols are mainly monohydric phenols, with the highest content of phenol, followed by m-cresol and p-cresol, which are generated from the scrubbing water and phenolic condensate water in the cooling and purification of coal gas, and the generation of phenolic condensate water depends on the quality of gasified coal and the gasification process. The treatment method of phenolic wastewater is as follows: steam chemical phenol removal method: use strong high-temperature steam to heat the phenolic wastewater, so that the phenol in the wastewater evaporates and escapes with the steam, and then the alkali solution is introduced to absorb it into phenyl sodium salt, so as to achieve the purpose of removing phenol; steam phenol removal method: steam phenol removal method is also called gas removal method, the phenolic wastewater is heated, and the phenol is volatilized with water vapor, and then the part of the phenolic steam is introduced into the furnace bottom of the generating furnace and mixed with air as a gasification agent, and the phenol is burned and decomposed into carbon dioxide and water in the furnace at high temperature to ultimately achieve the purpose of removing phenol; incineration method: the phenolic wastewater is sprayed into the incinerator, so that the phenolic organic matter is oxidized at a high temperature of about 1100 DEG C, and finally generates carbon dioxide and water for discharge.

[0003] At present, when the existing technology removes phenols by gas removal method, the phenolic wastewater is generally directly heated or stirred in the heating process until the phenolic wastewater no longer generates steam. Although this method can achieve the purpose of removing phenol, it needs to heat the phenolic wastewater for a long time, and because the phenolic wastewater contains oil, tar and other substances, as the heating time is prolonged, the water content will gradually decrease, and the density of the oil is lower than that of the water, which will cause the water to be below the oil, so that the water is difficult to evaporate, resulting in high cost of phenol removal, and the process of heating the phenolic wastewater cannot discharge the tar and other impurities at the same time, so it is impossible to continuously remove the phenolic wastewater by gas, which increases the burden of treating the phenolic wastewater and affects the efficiency of treating the phenolic wastewater.

[0037] In use, the phenolic wastewater is added into the tar pool 1 through the liquid adding pipe 5, and the particulate impurities in the phenolic wastewater will be precipitated in the tar pool 1, and then the electric heater 701 is started, and the temperature capable of evaporating the phenol water in the phenolic wastewater is set, the temperature sensor detects the temperature inside the evaporation tank 2, until the evaporation disc 702 reaches the corresponding temperature, at which time the liquid pumping mechanism 6 is started to pump the phenolic wastewater in the tar pool 1, and the phenolic wastewater is injected into the evaporation passage 703 opened at the top of the evaporation disc 702, so that the phenolic wastewater flows into the oil discharge pipe 705 through the spiral evaporation passage 703, and the phenolic wastewater entering the evaporation passage 703 will not overflow the evaporation passage 703.

[0047] The phenolic wastewater flows into the oil discharge pipe 705 through the spiral evaporation channel 703, and the phenolic wastewater entering the evaporation channel 703 will not overflow the evaporation channel 703, in this process, since the temperature of the evaporation disc 702 can evaporate the phenolic water, therefore, when the phenolic wastewater flows in the evaporation channel 703, the evaporation disc 702 will evaporate the phenolic water in the phenolic wastewater, and in the process of evaporation and flow of the phenolic wastewater in the evaporation channel 703, the multiple piercing heads 704 will cause the phenolic wastewater to branch, and as the phenolic water in the phenolic wastewater is gradually evaporated, there will be large droplets of phenolic water wrapped in tar, at this time, when the phenolic wastewater passes through the piercing head 704, the piercing head 704 can pierce the large droplets of phenolic water wrapped in tar, so that the phenolic water in the large droplets can flow out, thereby further evaporating the phenolic water, so that the phenolic water in the phenolic wastewater can be completely evaporated, shortening the treatment time of the phenolic wastewater, saving the cost, improving the recovery quality and recovery efficiency of the phenolic water in the phenolic wastewater, and the phenolic water vapor formed by the evaporation of the phenolic water will be discharged into the kiln through the vapor pipe 4 for combustion, thereby reducing the disposal cost of the phenolic wastewater and reducing the production cost;

[0048] Meanwhile, the operation of the servo motor 901 will drive the first bevel gear 903 to rotate through the rotating shaft 902, the first bevel gear 903 will drive the transmission shaft 906 to rotate through the second bevel gear 905, the rotation of the transmission shaft 906 will drive the fan blade 907 and the oil discharge pipe 705 to rotate, the rotation of the fan blade 907 will extract the phenol water steam formed by the evaporation of the phenol-containing sewage in the evaporation tank 2, and the phenol water steam will be injected into the kiln through the steam pipe 4, avoiding the accumulation of the phenol water steam in the evaporation tank 2, causing the phenol water steam to re-condense, thereby avoiding the evaporation disc 702 from evaporating the re-condensed phenol water steam, further improving the treatment efficiency of the phenol-containing sewage, saving resources, and the rotation of the oil discharge pipe 705 will drive the evaporation disc 702 to rotate, ensuring the uniformity of the heating of the evaporation disc 702, and at the same time, the phenol-containing sewage flowing in the evaporation channel 703 is separated from other liquids under the action of centrifugal force, facilitating the evaporation of the phenol water by the evaporation disc 702, further improving the evaporation efficiency of the phenol water, shortening the phenol water treatment time, and improving the phenol water treatment efficiency;

[0049] After the phenol water is evaporated, the oil, tar and other non-evaporated liquids formed will flow into the oil discharge pipe 705, the oil, tar and other non-evaporated liquids entering the oil discharge pipe 705 will fall into the oil storage pipe 803, and after the phenol-containing sewage is evaporated for a period of time, the oil pump 801 is started, so that the oil pump 801 extracts the oil, tar and other non-evaporated liquids in the oil storage pipe 803 through the oil extraction pipe 802, and the extracted liquids will be discharged through the heat exchange pipe 804, at this time, since the oil, tar and other non-evaporated liquids are liquids generated after the evaporation of the phenol-containing sewage, they have a high temperature, and when they are discharged through the heat exchange pipe 804, they will heat the phenol-containing sewage in the tar pool 1, increase the initial temperature of the phenol-containing sewage, and thus improve the fluidity of the oil, tar and other substances in the phenol-containing sewage, facilitate the subsequent evaporation of the phenol water in the phenol-containing sewage, and further improve the recycling efficiency of the phenol water in the phenol-containing sewage, and the heated phenol-containing sewage in the tar pool 1 will be partially evaporated under the action of temperature, and the gas formed by evaporation will be discharged through the one-way exhaust pipe 11 into the evaporation tank 2 and then discharged into the kiln through the steam pipe 4.

It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application.
