The invention relates to a technology of waste thermal oxygenolysis, and in particular relates to an efficient thermal oxidation furnace for low afterburning-amount smoke constant-speed grading reaction. The thermal oxygenolysis furnace comprises a furnace body and a combustor (1); the combustor (1) arranged at the front end of the furnace body is provided with a combustion-supporting air inlet (1.1); the furnace body comprises a combustion section (2) and multiple stages of thermal oxygenolysis sections; the combustion section (2) is provided with a waste gas inlet (2.1); each of the multiple stages of thermal oxygenolysis sections is provided with a waste gas inlet, a first-stage air inlet and a second-stage air inlet; the waste gas inlet of each stage of thermal oxygenolysis section is positioned between the first-stage air inlet and the second-stage air inlet; the waste gas from the combustion section and the multiple stages of thermal oxygenolysis sections and air enter the furnace body at an included angle of 20-60 degrees relative to the axle of the furnace body; and the flow rates of smoke in the combustion section and the multiple stages of thermal oxygenolysis sections are equal. The furnace has the characteristics of strong combustion stability, low mixing amount of high-grade fuel, simple and reliable structure, stable and complete oxygenolysis, high efficiency and low cost, and is convenient to operate.

The invention provides a two-stage magnetic induction reinforced Fenton reaction sewage treatment device. The device comprises a tank body, magnetic induction coils on the outer side wall of the tankbody as well as a spiral adjusting pipe in the center of the tank body, wherein a spiral center pillar is arranged on the spiral adjusting pipe, and a plurality of spiral blades are arranged on the spiral center pillar; the bottom and the middle of the spiral adjusting pipe are connected with a pretreatment water inlet pipe and a hydrogen peroxide adding pipe respectively; a top water outlet of the spiral adjusting pipe is located in the tank body; a plurality of aerated plug-flow pipes are arranged on one side in the tank body; a water outlet pipe provided with a valve is arranged in the middle of one side wall of the tank body. The invention also provides a method for treating sewage by use of the device. The Fenton reaction effect is strengthened through a magnetic field, and the purpose of promoting decomposition of pollution matter such as COD, ammonia nitrogen and the like is achieved; the spiral adjusting pipe and the aerated plug flow pipes are used for two-stage adjustment andreinforcement of the magnetic field, the effect of adjusting the magnetic field strength, the Fenton reaction mixing degree and the reaction time is realized, and the sewage effluent quality is notably improved; with nano magnetic powder as a Fe<2+> provider, the iron sludge output can be reduced.

The invention discloses a graphene preparation method. The method comprises the processes of liquid phase expansion treatment, ultrasonic peeling and drying, and the ultrasonic peeling process comprises the following steps: adding a peeling solution and wormlike graphene aggregation obtained after the liquid phase expansion treatment into a tank body provided with a plurality of ultrasonic vibration rods in proportion, introducing compressed air into the tank body to bubble and stir in order to make the wormlike graphene aggregation dispersed and suspending in the peeling solution, and controlling the ultrasonic vibration rods to carry out ultrasonic vibration treatment for 0.5-20h in order to obtain a flocculent graphene suspension. The method allows the wormlike graphene aggregation to be uniformly dispersed in the peeling solution, so the peeling effect is improved, and the peeling time is shortened.

The invention relates to an energy-saving green high-strength concrete preparation method, which uses an energy-saving green high-strength concrete preparation device, the energy-saving green high-strength concrete preparation device comprises a crushing mechanism, a screening mechanism and a mixing mechanism, and the present invention adopts a multi-stage treatment The designed pulverizing mechanism realizes the pulverization of waste residue through the back and forth grinding motion, and the pulverization effect of different sizes of waste slag is improved by changing the grinding distance, thereby improving the overall pulverization effect of the waste slag. , the set screening and feeding mechanism can realize the screening treatment of slag and cut off the dust generated by screening, and the movable connection method adopted by the stirring structure in the mixing mechanism can facilitate the smooth progress of disassembly and cleaning, thereby avoiding this problem. The surface of the structure forms a thicker concrete adhesion crust, which affects the effect of mixing and stirring.

The invention relates to anti-clogging structured packing which consists of a packing body. The packing body is formed by connecting and combining n packing units (n is greater than or equal to 2) along the extending directions of liquid collecting tanks; the extending directions of the liquid collecting tanks of all the packing units are parallel with one another and same; the outer edge of each upper wing and the outer edge of each lower wing of each packing unit are respectively connected with the outer edge of each upper wing and the outer edge of each lower wing of the adjacent packing unit in a same layer, and meanwhile, the outer edge of each upper wing of each packing unit is connected with the outer edge of each lower wing of the former packing unit, and the outer edge of each lower wing of each packing unit is connected with the outer edge of each upper wing of the next packing unit. Each packing unit comprises a pair of upper wings, a pair of lower wings and a liquid collecting groove. The size of each upper wing is as same as an elevation angle beta and the size of each lower wing is further as same as an elevation angle theta. The roots of the upper and lower wings on the same side of each liquid collecting tank are alternately connected with the edge of each liquid collecting tank. The section of each liquid collecting tank body is V-shaped. When the anti-clogging structured packing is horizontally placed, each V-shaped opening faces upward.
