Fine particulate matter removal device and method with combined action of acoustic agglomeration and cyclone separation

Abstract

The invention discloses a fine particulate matter removal device and method with combined action of acoustic agglomeration and cyclone separation. The device is embedded in each terminal workstation in an MIS system, is used for adding an invisible watermark to an acquired new image, and also provides integrity detection and tampering localization analysis for terminal work management and image processing. The technical method is embedded and integrated into a management information system for authenticating image content integrity and locating a tampered image region, and the method can be expressed as integrated external hardware when in concrete realization. The realization of the whole device scheme is divided into two parts: one, image characteristic information as the watermark is generated by the original image, the watermark information is subjected to chaotic encryption and then embedded into the original image, and the invisibility of the watermark information is realized under a condition without increasing the bandwidth; and two, a watermark-containing medical image is subjected to watermark extraction on a receiving end, the image can be subjected to integrity detection, the tampered image region is located, and thus a strong support is provided for further decision.

Description

Technical field [0001] The invention belongs to the technical field of sewage control equipment manufacturing, and relates to a device and a method for removing fine particles through the combined action of acoustic condensation and cyclone separation. Background technique [0002] Inhalable particulate matter refers to the general term for particulate matter that can enter the human respiratory tract through the nose and mouth, represented by PM10 (particles with an aerodynamic diameter of less than 10 microns). Among them, the finer is PM2.5 (aerodynamic diameter less than 2.5 microns), also known as fine particulate matter or pulmonary particulate matter, which can enter the human alveoli and even the blood circulatory system, directly causing cardiovascular diseases and other diseases. At present, the pollution of inhalable particulate matter has become a prominent atmospheric environmental problem, which has attracted great attention from countries all over the world. It is...

Problems solved by technology

[0013] Among the patents related to the removal of particulate matter retrieved above, none of them can achieve the removal of PM2.5 particulate matter in a cost-effective manner

Although the first and second patents use the sonic agglomeration technology, they are only used as the pretreatment link of dust removal, and the efficiency of agglomeration does not reflect the principle. The large particles after agglomeration need to rely on subsequent traditional conventional methods for secondary treatment. It cannot be used as an independent PM2.5 dust removal device; the third patent uses ultrasonic agglomeration technology, because the ultrasonic dust removal effect is not good at low power, and the energy consumption of ultrasonic waves is large at high power, it is difficult to maintain stable and reliable Removal of PM2.5 particulate matter; the remaining several patents use liquid additives and involve new sewage discharge control issues
