The working principle is as follows:
when the deep coal chemical wastewater treatment fluidization equipment works, firstly, chemical wastewater is poured into the auger pipe 21 from the water inlet pipe 211, the first motor 23 is started to drive the auger 22 to rotate, impurities with large volume of oil sludge in the wastewater are screened and transported to the position of the sludge discharge pipe 212 through the auger 22, and the impurities with large volume of oil sludge are transported into the sludge storage box 24 through the sludge discharge pipe 212;
the waste water primarily screened by the auger 22 can be screened and collected by the deoiling unit 3; then the wastewater flows into the machine body 1; firstly, wastewater flows through a water discharging plate 51 on a steam unit 5, a high-temperature steam generator 54 changes water into high-temperature steam, the generated high-temperature steam enters the machine body 1 through a steam pipe 53 and a steam pipe groove 512 to be contacted with the wastewater, the high-temperature steam distills some volatile substances such as ammonia in the wastewater from the wastewater, and the distilled substances drive an exhaust fan 42 to rotate and discharge the volatile substances out of the machine body 1 along an exhaust pipe 43 by starting a second motor 41;
the distilled wastewater flows to the spray plate 61 on the oxidation unit 6 through the drain holes 511 on the drain plate 51; the wastewater flows down uniformly from a plurality of spray headers on the spray plate 61, the ozone in the ozone tank 63 and the column tank enters the machine body 1 through the oxygen discharge ports to fully contact with the wastewater to generate oxidation reaction, the ozone oxidation is favorable for reducing the COD (chemical oxygen demand) of the wastewater generated by the coal chemical industry, the chromaticity and turbidity of the wastewater can be reduced, no secondary pollution is generated in the process, the ozone can carry out advanced treatment on the wastewater of the coal chemical industry, 40 to 50 percent of the COD can be treated, and the heterocyclic organic matters and the phenolic organic matters have very remarkable effects; finally, the wastewater after layer-by-layer treatment is discharged out of the machine body 1 through a water outlet 11; in the prior art, each treatment step of wastewater cleaning needs specific equipment to be realized, so that the floor area of wastewater treatment equipment is greatly increased; according to the invention, the chemical wastewater is gradually cleaned through the desilting unit 2, the deoiling unit 3, the steam unit 5 and the oxidation unit 6, so that one device can complete multiple cleaning tasks, the floor area of the wastewater treatment device is greatly reduced, and the units are mutually matched and are gradually advanced layer by layer, so that the chemical wastewater treatment device has integrity.
When large impurities such as oil sludge in the wastewater are screened by the auger 22, the surface of the fan blade of the auger 22 is provided with a plurality of through holes with the diameter smaller than that of the impurities, so that the wastewater can smoothly circulate, and the impurities cannot circulate down; and the surface of the fan blade of the packing auger 22 is provided with an adsorbent which can adsorb some phenolic substances in the wastewater.
The wastewater screened by the auger 22 and treated by the adsorbent enters the oil screening pipe 31 of the deoiling unit 3, firstly passes through a water-oil separation membrane on the surface of an annular sieve plate 311 in the oil screening pipe 31, and the water-oil separation membrane can block water by oil passing through, so that the oil in the wastewater enters the inner edge position of the oil screening pipe 31 through the water-oil separation membrane, and is discharged into the oil storage tank 33 through the oil discharge pipe 32 for centralized collection; and be equipped with sieve 312 and oil-water separation membrane in sieve oil pipe 31 lower extreme mouth of pipe department, oil-water separation membrane can let water pass through and block oil, prevents that some grease from not being collected just being taken out by waste water and carrying out next step's processing.
When the wastewater flows down through the lower water holes 511 on the lower water plate 51, the wastewater can flow down along the water-following plate 55 by arranging the water-following plate 55, so that a water curtain is formed on the surface of the water-following plate 55, the middle of the water-following plate 55 is provided with a steam through groove 551 communicated with the steam pipe groove 512, and the steam through groove 551 sprays high-temperature steam through a steam outlet to contact with the wastewater for distillation; the steam and the waste water are fully contacted through the formation of the water curtain and the arrangement of the plurality of steam outlets, so that the distillation is more fully and better in distillation effect.
The distilled gas is discharged into the exhaust pipe 43 by the exhaust fan 42; because the exhaust pipe 43 is communicated with the ozone tank 63 and the movable block 631 is connected between the exhaust pipe 43 and the ozone tank 63 in a sliding and sealing manner, the distilled gas pushes the movable block 631, and the movable block 631 pushes the ozone in the ozone tank 63 to help the ozone to be discharged and react with the wastewater in a contact manner; and after the movable block 631 moves, the inlet of the condensation air storage tank 64 at the bottom of the movable block 631 is exposed, and the distilled gas enters the condensation air storage tank 64 for collection.
When the adsorbent on the surface of the fan blade of the packing auger 22 is used for a long time, excessive adsorbate is adsorbed, so that the adsorption capacity of the adsorbent is reduced, at the moment, a valve between the connection of the oxygen conveying pipe groove 65 and the ozone groove 63 can be opened, so that ozone in the ozone groove 63 enters the packing auger pipe 21 from an oxygen discharge port on the upper wall of the packing auger pipe 21 along the oxygen conveying pipe groove 65, a one-way valve is arranged in the oxygen discharge port to prevent wastewater from flowing into the oxygen conveying pipe groove 65 through the oxygen discharge port, the adsorbent on the adsorbent is subjected to strong oxidative decomposition by using ozone, so that the adsorbent is regenerated, the adsorption effect of the adsorbent is enhanced, and the service life of the adsorbent is prolonged.
The treated wastewater flows into the drain pipe through the drain port 11, one part of the wastewater is discharged from one outlet of the drain pipe, and the other part of the wastewater enters the high-temperature steam generator 54 through the other outlet for producing high-temperature steam, so that the water resource is recycled, and the treated wastewater enters the machine body 1 again in the form of steam and can be subjected to primary oxidation treatment again, so that a better treatment effect is achieved.
