Beneficial effects of the present invention:
(1) present invention utilizes the special construction of oil water separator, make mink cell focus and light oil autologous density can be relied on to make mink cell focus and light oil be able to separate collection in the oil-water separation stage, avoid increasing subsequent technique and man-hour the mink cell focus to collecting and light oil be easily separated, decrease man-hour, reduce cost, improve the utilization ratio of equipment, and spray treating column, oil water separator, expansion chamber and conical baffle coaxial line, it is ensured that stability when spray treating column and oil water separator operating。
(2) oil water separator of the present invention conical outlet in arrange rotate element the liquid in oil water separator can be stirred, while acceleration mink cell focus separates with light oil, rotate when element rotates and may also reach up the unforeseeable effect of such a:, when rotating element rotation, rotate member upper and can form low-pressure area, facilitate the liquid in Vertical Channel to circulate downwards;Additionally, rotate and can also apply pressure to rotating element lower portions liquid when element rotates, force liquid below conical outlet to flow to oil water separator surrounding so that it is in mink cell focus and light oil float up, it is to avoid part mink cell focus and light oil are trapped near conical outlet to be difficult to discharge。
(3) it is provided with discharge duct in the Vertical Channel of the present invention, it is to avoid build-up of air in conical outlet, hinders downward liquid flow in Vertical Channel。
(4) present invention utilizes heating coil that cyclone dust extractor is heated, make to be higher than flue gas dew point temperature with the surface temperature of high-temperature flue gas contact surface in cyclone dust extractor, avoid the generation of leak source corrosion phenomenon, ensure that flue gas maintains higher temperature in two stage treatment tower simultaneously, the a large amount of vaporific water droplet produced when utilizing the water that high-temperature flue gas sprays out with shower nozzle to contact, composition condensable in flue gas is carried out condensation adsorption, condensable composition is condensed by endothermic reaction when simultaneously moisture can also be utilized to evaporate, additionally, utilize and heating-up temperature can be had more flexible control during heating coils heat。
(5) present invention first pass through cyclone dust extractor carry out independent dust removal process again through spray treating column in shower nozzle carried out spray process, and dust is very easily adhere to a large amount of mink cell focus and light oil composition, first carry out mink cell focus and light oil composition that independent dust removal process is equivalent to remove in flue gas one step ahead, thus the mink cell focus more thoroughly removed in flue gas and light oil composition, dust itself is also able to more remove thoroughly simultaneously。
(6) packing layer that the present invention adopts makes the gas of rising longer with the time of contact of the ejecting liquid of decline, contact more abundant, what in gas, the condensation process of mink cell focus and light oil composition carried out is more abundant, and mink cell focus and lightweight oil separating are more thorough。
(7) high-temperature flue gas is through the process of cyclone dust extractor of the present invention, in gas, solid content is few, therefore the moisture in expansion chamber can be circulated utilization, it is to avoid often the water in expansion chamber is carried out purified treatment, while having saved water resource, decrease cost;Simultaneously containing part mink cell focus and light oil in recirculated water, this part mink cell focus and light oil with water when packing layer declines, stickiness by oil itself can reduce the speed that liquid declines in packing layer, thus increasing the time of contact of liquid and uprising gas, make contact more abundant, in gas, the condensation process of mink cell focus and light oil composition is more abundant, and mink cell focus and lightweight oil separating are more thorough。
