Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The oil field measure liquid treatment system shown in the attached figures 1 to 4 comprises a dosing unit 1, a sedimentation unit 2, an air flotation unit 3 and a filtering unit 4 which are connected in sequence; the chemical adding device is characterized in that a stirrer 5 is arranged in the chemical adding unit 1, a sedimentation inclined plate 6 is arranged in the sedimentation unit 2, the bottom of the air flotation unit 3 is connected with a dissolved air pump 7, and a scraper 8 is arranged at the top of the air flotation unit 3.
The chemicals added into the dosing unit 1 at least comprise a PH regulator, a coagulant aid, a flocculating agent and an ion removal agent, and suspended matters, heavy metals and the like in the liquid are formed into large flocs; the sedimentation unit 2 is used for removing large flocs formed in the previous step, and the inclined plate sedimentation is adopted to ensure the sedimentation effect and reduce the occupied area; the dissolved air pump is used for removing mineral oil and the like in the liquid; the filtering unit 4 further removes tiny particles in water by combining a quartz sand filter 9 and a large-flux filter 10. The quartz sand filter 9 is provided with a backwashing pump, an air compressor and an air tank to realize combined backwashing of air and water.
The scraper conveyor 8 is obliquely arranged, for convenience of description, the higher end of the scraper conveyor 8 is called an end A, the lower end of the scraper conveyor is called an end B, and the oil scraping cavity 12 moves from the end B to the section A and gradually breaks away from the liquid level. The transmission device 13 of the scraper conveyor is distributed with an upper row of scrapers 11 and a lower row of scrapers 11, one end of each scraper 11 is fixedly connected with the transmission device 13, and the other end of each scraper 11 forms a scraper cavity 12; the transmission device 13 drives the oil scraping cavity to move repeatedly, and grease floating on the air floatation unit 3 is taken away.
