A degradation trend of the system is determined according to the real-time voltage oscillation signal and a reference voltage oscillation signal corresponding to the detection circuit of the system. A failure detection for the system is performed according to the degradation trend of the system.

Screw extruder, and fiber spinning, drafting and winding combined machine for polylactic acid industry

Disclosed are a screw extruder and a combined spinning-drawing-winding machine for industrial polylactic-acid fiber. The screw extruder includes a threaded sleeve (1-a) and a threaded rod (1-b) penetrating in the threaded sleeve (1-a). The threaded rod (1-b) includes a feed section (1-5d), a compression section and a metering section (1-5a). The threaded sleeve (1-a) includes a gas collection chamber (1-3g) and an exhaust hole (1-3d). The gas collection chamber (1-3g) is opened and disposed on an inner wall of a junction of the compression section and the metering section (1-5), A gas is collected through the gas collection chamber (1-3g). The gas generated by a hydrolysis is discharged from the exhaust hole (1-3d) by controlling an on-off valve (1-3). When the melt enters the metering section (1-5a), the gas is removed in time, thereby overcoming the serious adverse impact of the gas from the hydrolysis on the spinning. The unfavorable situation of end breakage is eliminated, and a subsequent spinning quality and a spinning efficiency are guaranteed.

Pulverized coal fired boiler with wall-attachment secondary air and grid overfire air

The present invention relates to a pulverized coal fired boiler with wall-attachment secondary air and grid overfire air. Primary burners including primary air spouts, secondary air spouts and close coupled overfire air spouts arranged at intervals along the height direction of a hearth are arranged on four corners of the hearth. Two-way wall-attachment secondary air spouts and one-way wall-attachment secondary air spouts are arranged from bottom to top in a primary combustion zone where the primary burners are located. One-way wall-attachment secondary air spouts are arranged in a reduction zone between the primary burners and the top overfire air spouts, and grid overfire air spouts are arranged in a burnout zone where the overfire air is supplied. By adopting the pulverized coal fired boiler with wall-attachment secondary air and grid overfire air according to the present invention, the NO amount generated in the hearth is reduced, the NO reduction rate along a flame is improved, the coke burnout rate is improved, less coke which is not burnt out enters into the burnout zone, slagging on the water-cooled wall is reduced, and ultralow emission of NOx may be realized on the premise that the combustion efficiency is not reduced, slag is not agglomerated in the hearth and the flue gas temperature deviation is small.
