An optimization method for a directional preparation technique and efficient use of semi-coke for blast furnace injection. Firstly, the volatile and the ash content of target semi-coke are preset, and then the volatile and the ash removal percentages of a raw coal are calculated; after ash removal, several sets of dry distillation carbonization temperatures and carbonization times are obtained according to the volatile removal percentage, and the relationships between a combustion rate, abrasiveness, explosiveness and jet flow property and the carbonization temperature are respectively established to obtain the optimal actual carbonization temperature; and semi-coke for blast furnace injection is obtained at an actual carbonization temperature. The directional preparation is suitable for the semi-coke for blast furnace injection, and an optimal coal-compounding scheme is obtained, thus achieving the efficient and safe injection of blast furnace iron-making fuels, and energy conservation and emission reduction.

A gasifier for organic solid waste by injection into molten iron and slag bath includes a gasification furnace, a liquid level adjusting furnace and a slag discharge and heat exchange shaft furnace. The liquid level adjusting furnace, in communication with the bottom of the gasification furnace, contains 1200-1700&#xb0; C. molten iron-based alloy liquid, which is covered with molten liquid slag layer. When gas pressure above or liquid volume in the liquid level adjusting furnace increases, liquid level of the molten liquid in the gasification furnace rises simultaneously. A particle material injection lance is immersed, through which organic particles to be gasified are blown into molten bath, and oxygen gas or oxygen-enriched air as gasifying agent is blown into the melt at the same time. Organic substance is gasified into CO-rich and H-rich syngas, and most of inorganic substance enters molten slag and is discharged termly.

Disclosed is a PCB Rogowski coil, comprising two groups of first coils and second coils which are connected in series and have opposite winding directions, wherein the first coil and the second coil respectively contain a plurality of wire turns. One wire turn of the first coil comprises an inlet wire, a winding wire and an outlet wire. The winding wires of each wire turn of the first coil are arranged in radially parallel with each other. The winding wires are respectively arranged on both the upper surface and the lower surface of a PCB board, with the inlet wire passes through a via hole on the PCB board and is connected to the winding wire. The interference of an external magnetic field is therefore markedly eliminated, and the anti-external interference capability of a Rogowski coil is improved.
