The invention relates to a bound floating pipeline towing pipe method. In the method, a floating pipe is used for replacing a buoy in the prior bound buoy towing pipe method, the specification of the floating pipe is 820x8mm, each segment is 50m in length and is an independent sealed bin, a plurality of supporting ribbed plates and longitudinal ribbed plates are welded inside, an air valve and a water valve are arranged for marine load adjustment, every two segments are connected through an inner flange, and a towing head is respectively arranged at both ends of the whole body. The invention has the advantages that the problem of size limitation for a process pipe in the bound buoy towing pipe method is solved, and the requirement for sea conditions is also greatly broadened; meanwhile, the problem that a frock pipe can not be reclaimed in a bunched pipeline towing pipe method is also solved, so that a floating pipe device can be repeatedly utilized, and the construction cost of submarine pipeline laying is further lowered.

The invention discloses a control method of an active clamp flyback converter. In the flyback transformer, the main switch tube controls the current magnitude of the primary winding of the flyback transformer, and the clamp switch tube controls the primary side of the flyback transformer. The node voltage is clamped, and the controller generates a control signal for controlling the main switch tube and the clamp switch tube by detecting the feedback voltage; when the converter works at a light load, a fixed dead time passes after the main switch tube is turned off Immediately turn on the clamp switch tube, the converter charges the clamp capacitor through the clamp switch tube to recover leakage inductance energy, wherein the conduction time of the clamp switch tube is less than the leakage inductance and the output junction capacitance of the main switch tube and the clamp switch tube the resonance period. The present invention does not need to connect a large resistor in parallel to the clamp capacitor, thereby improving the light-load efficiency.

The invention relates to a sinter waste heat and sintering flue gas pollutant cooperative treatment process. The treatment process comprises the steps that sintering flue gas generated by metallurgy sintering is subjected to dedusting treatment to remove particulate matters to be then subjected to heat exchange treatment with sinter generated by metallurgy sintering, and at least part of CO in thesintering flue gas is oxidized and removed during heat exchange treatment; and the sintering flue gas is subjected to CO desorption treatment, and at least part of CO in the sintering flue gas is oxidized and removed during CO desorption treatment. According to the arrangement conditions of a sintering machine and a gas desulfurization system at present, the sintering flue gas can adopt the technology that SO2 is firstly or lastly desorbed. The cooperative treatment process solves the problems about CO desorption and utilization, and cooperative treatment of sinter waste heat and sintering flue gas pollutant is achieved.

The invention relates to the technical field of cooling of an air-permeable material and provides an air-cooling device and method for an air-permeable material. According to the air-cooling device for the air-permeable material, multiple layers of material storage barrels are arranged, and discharging holes in bottom plates of the adjacent material storage barrels are distributed in a manner that the projections of the discharging holes in a vertical direction are staggered, so that the height that the material drops each time is the height of each material storage barrel, and the problems of large material height difference and high pulverizing rate are solved. On the basis, material rakes making relative motion with the material are arranged in the material storage barrels, and the material is gathered or dispersed under the agitating action of the material rakes, so that the stroke of the material is longer under the condition of the same height, the material is in full contact with cooling gas, the cooling time is longer, and accordingly, the heat exchange efficiency is improved. Moreover, the device is vertically arranged, so that the occupied area is small.
