Description

Mixed hydrocarbon rectification separation sewage treatment equipment Technical Field The application relates to the technical field of sewage treatment equipment, in particular to mixed hydrocarbon rectification separation sewage treatment equipment. Background In petrochemical production, hydrocarbon-rich sewage and its derivative may be produced through hydrocarbon-mixing rectification and other process, and features that the sewage is treated with air floatation sewage treating apparatus to eliminate free oil, emulsified oil and suspended oil. The existing air floatation sewage treatment equipment comprises a mixing tank, an air floatation tank, a separation tank, a collecting tank and a clean water tank which are sequentially arranged, when the air floatation sewage treatment equipment works, firstly, the adding and mixing reaction of a medicament is completed in the mixing tank, then the sewage enters the air floatation tank, a large amount of microbubbles released by an air dissolving mechanism in the air floatation tank are attached to pollutants, float to the water surface and are gathered to form a floating slag layer, a driving mechanism drives a scraping plate to slowly move from the separation tank to the collecting tank, the scraping plate is used for scraping scum into the collecting tank in cooperation with a weir plate, and the separated sewage enters the clean water tank through a pipeline. In the operation process of the air floatation sewage treatment equipment, the scraper blade performs circular motion at the inclined flat-plate weir plate to ensure that the contact position of the tail end of the scraper blade and the scum has larger linear speed compared with horizontal movement, so that the scum is quickly separated from the weir plate surface after being contacted with the bottom of the weir plate in the rotation process of the scraper blade, the scum moves along the weir plate surface through residual kinetic energy and enters the collecting tank, but still part of scum remains on the weir plate surface and slides back into the separating tank under the action of gravity, the integral sewage treatment efficiency is influenced, and the possibility that the scum flows into the clean water tank is increased. The current weir plate is fixed to be set up on the pool wall of collecting vat with detachable mode usually through the bolt, if adopt with the arc weir plate of scraper blade rotation radius looks adaptation to guarantee the laminating of scraper blade and weir face at scraper blade pivoted in-process, then need change the weir plate of corresponding camber when adjusting the weir plate height, and be inconvenient for confirming the interval of weir plate to scraper blade center of rotation, lead to this sewage treatment plant's adaptability to reduce. If a telescopic scraper is adopted, for example, a spring telescopic part which is in a trend of extending towards a direction far away from a rotation center is additionally arranged on the inner side of the scraper, the outer side rotation radius of the scraper and the telescopic plate forming the scraper is relatively increased, so that the relative speed of the telescopic part when the scraper contacts with a weir plate after the telescopic part is contracted is ensured, the linear speed is higher when the subsequent scraper is re-filled with water, the telescopic part is caused to strike a water body, and scum in the region is easy to reprecipitate. If the guide chain wheel is additionally arranged to enable the scraping plate to move in the parallel direction of the weir plate in the weir plate area, the moving speed of the scraping plate is reduced relative to the circular motion, the length of time for the scraping plate to pass through the weir plate area is increased, partial scraping slag is easy to fall back along a gap on the inner wall of the scraping plate separation tank under the action of gravity, and the sewage treatment efficiency is relatively low. Disclosure of Invention The application provides mixed hydrocarbon rectification separation sewage treatment equipment which has the advantages of adaptively adjusting the gesture of a weir plate according to the rotation state of a scraper plate and ensuring the contact speed of the scraper plate and the weir plate, and is used for solving the problem that when scum is driven by the scraper plate to pass through the weir plate, part of scum still stays on the weir plate and falls back, so that the sewage treatment efficiency is reduced. In order to achieve the aim, the application adopts the following technical scheme that the mixed hydrocarbon rectifying and separating sewage treatment equipment comprises a shell, a separating tank and a collecting tank, wherein a plurality of chain wheels are arranged at the top of the separating tank in a rotating way, a chain is connected between two chain wheels which are positioned on the same plane in the radial direction i
