Control method for preventing explosion venting of dry dedusting system in converter smelting process

ActiveCN102952917AReduce CO contentSolve the problem of ignition lagManufacturing convertersIgnition delayNitrogen gas
The invention discloses a control method for preventing explosion venting of a dry dedusting system in converter smelting process. The control method includes the steps of: firstly adding steel scraps into a converter, and then feeding molten iron into the converter; supplying oxygen to the liquid surface of the molten iron from the top through a oxygen lance, feeding stirring gas into the molten iron from the bottom to dephosphorizing the molten iron, at the same time controlling the oxygen supply intensity at all periods of time, and purging a flue of the converter for 90seconds through nitrogen 30seconds before the dephosphorization process is finished; bringing up the oxygen lance after the dephosphorization process is finished and conducting rapid deslagging operation to the converter; and decarbonizing the molten iron, bringing up the oxygen lance after the decarbonization process is finished, and then tapping of molten steel is carried out. According to the invention, in the method, the nitrogen purging time is set through a PLC(Programmable Logic Controller) program, the opening degree of an oxygen flow valve of the converter is set to be 40% and the oxygen release point of the oxygen lance of the converter is set to be 13.73m. Therefore, the problem of ignition delay upon release of oxygen is solved and the problem that explosive gas mixture is easy to produce in the dephosphorization process after the oxygen lance is brought up is avoided. The control method is simple and effective and is low in cost.

Lagrange puff atmospheric diffusion simulation method in nuclear accident off-site consequence evaluation

The invention discloses a Lagrange puff atmospheric diffusion simulation method in nuclear accident off-site consequence evaluation. A Lagrange mesoscale atmospheric diffusion puff mode is used for calculating the concentration and the dosage of gaseous radioactive materials in each grid point of an evaluation area, and a land-surface and inhomogeneous unstable change meteorological condition of a medium complex degree can be favorably processed. On an appointed grid, one series of Gaussian puff is released to simulate the change of nuclide along with time, and the accident situations of a plurality of releasing points can be simulated in the same time period. The method cites the calculation of aspects including diffusion parameters related to stability, plume rise, thermal inversion layers, ground reflection, dry and wet source item depletion and the like; and under a complex topographic condition, puff division is adopted to process a puff furcation problem, and a mesoscale simulation result more approaches to a practical environment condition. By use of the method, the instantaneous concentration of the nuclide in near ground air, time integral air concentration, ground deposition concentration, smoke plume, the [Gamma] dosage rate of ground deposition and the like can be calculated.

Smart logistics space-ground collaborative system control method

InactiveCN108628346ATake off and landSolve the disadvantages of deliveryTarget-seeking controlPosition/course control in two dimensionsLogistics managementMulti machine
The invention discloses a smart logistics space-ground collaborative system control method. A logistics vehicle plus unmanned aerial vehicle distribution mode is adopted. A large number of goods are carried on a logistics vehicle to run on a main road, an unmanned aerial vehicle can take off automatically on the moving logistics vehicle when closing to a delivery point of a cargo receiving point,and the position of the delivery point of the cargo receiving point is sent to the unmanned aerial vehicle through a system management center. The unmanned aerial vehicle can navigate to a rough position, and a special target can be accurately recognized through a binocular stereoscopic vision technology to land at a cargo release point. The position of the logistics vehicle is sent to the unmanned aerial vehicle in real time through the system management center, after the unmanned aerial vehicle finishes cargo throwing. The unmanned aerial vehicle can fly back to the vicinity of the logisticsvehicle automatically and dynamically lands on the vehicle to wait for next delivery task. In this way, the space-ground efficient coordination work and the multi-machine cooperation function can berealized. According to method, a new battlefield of logistics transportation is created, and the problems of high-efficiency mass distribution and long-distance distribution can be solved.
