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.
The bottom surface of the oil scraping chamber 12 is an inclined surface, one side surface of the oil scraping chamber 12 is a movable plate 14, the bottom of the movable plate 14 is hinged with the oil scraping chamber 12, and the movable plate 14 is arranged on the lower side of the bottom surface of the oil scraping chamber 12.
