The generator set provides electric energyfor the electromagnetic drag reduction module; the electromagnetic control module comprises thin strip-shaped magnets, thin strip-shaped electrodes, a fixing frame and a rechargeable battery, the overall shape of the module is consistent with the shape of an airfoil and is tightly attached to the airfoil of the unmanned underwater vehicle, an electromagnetic activation plate is composed of strip-shaped magnets and strip-shaped electrodes which are arranged at intervals, the polarities of the tops of every two adjacent strip-shaped magnets are opposite, and the polarities of every two adjacentstrip-shaped electrodes are opposite. The thickness of the electrode is equal to that of the magnet, and the electrode and the magnet are fixed and connected through the fixing outer frame. And the electrode magnetic poles are arranged in parallel along the flow direction. The device provides electric energy for the electromagnetic drag reduction module, and the purposes of energy conservation and emission reduction are achieved.

Wastewater advanced treatment process adopting flocculation precipitation method
InactiveCN111635030AEasy to handleStable emissionsGeneral water supply conservationTreatment involving filtrationActivated carbonFlocculation
The invention discloses a wastewater advanced treatment process adopting a flocculation precipitation method, and belongs to the field of sewage treatment. The process comprises the following steps: filtering the wastewater through a grid and a twill filter screen in sequence; introducing ozone into the wastewater, and fully stirring the wastewater; adding activated carbon into the wastewater, fully stirring the wastewater, and filtering; feeding the wastewater into a primary flocculation tank, adding a polysilicate aluminum ferric flocculant into the primary flocculation tank, and finally carrying out solid-liquid separation to obtain a supernatant and a flocculation precipitate; feeding the supernatant into a secondary flocculation tank, adding polyacrylamide into the secondary flocculation tank, and finally performing solid-liquid separation to obtain a supernatant and a flocculation precipitate; and carrying out ultrafiltration, and introducing the supernatant into a water collecting tank. The wastewater is subjected to deep treatment based on the flocculation precipitation method, such that the wastewater treatment effect can be effectively improved; and the process has advantages of simple treatment operation, low cost, no by-product generation and the like, and is suitable for promotion and application.

A process for separating and recovering carbon dioxide from industrial tail gas
ActiveCN103463955BReduce energy consumptionRealize the goal of energy saving and emission reductionProductsReagentsDistillationProcess engineering
The present invention disclosed a process that is separated from the industrial exhaust gas to recycle carbon dioxide. It mainly uses the highly integrated means of energy -heat pump distillation technology.The absorbing solution is contacted to get the rich liquid; the liquid liquid is divided into two shares through the downturn after the liquid pump.Enter the solution tower and absorb, and the carbon dioxide with a small amount of water steam is discharged from the top of the suction tower with a small amount of water steam.use.This process is based on the traditional carbon dioxide capture process, integrates diverting and absorbing and heat pump distillation process, and effectively uses the steam potential heat of the pagoda to reduce the energy consumption during the system operation.Carbon dioxide products reduce greenhouse gas emissions.
