The invention discloses a novel sludge drying processing device, and belongs to the technical field of environmental protection equipment. The novel sludge drying processing device comprises a feeding machine, an air blower, an air heater, a diffuser, air flow dryers, a cyclone dryer, a cyclone separator, a dust remover, and an induced draft fan; air is heated by the air heater to a temperature higher than 100 DEG C, is delivered into the diffuser, and is mixed with dewatered sludge so as to obtain a hot air sludge flow, wherein water content of the dewatered sludge is controlled to be 80%, and the dewatered sludge is delivered into the diffuser via the feeding machine, and is smashed using the diffuser; sludge in the hot air sludge flow is dried using the air flow dryers and the cyclone dryer, dried air sludge flow is delivered into the cyclone separator so as to obtain dried sludge with a water content less than 5% via separation; hot air and dried sludge dust are delivered into the dust remover; and dried sludge dust is discharged via the bottom of the dust remover. The novel sludge drying processing device is used for processing sludge using a man-made heat source, deep dewatering is realized, thermal treatment effect is achieved, the activity of microorganisms in sludge are inhibited, and the obtained dried sludge can be taken as fertilizers, building materials, and the like.

Converter station near-zone short-circuit current control method and system

InactiveCN111509753AImprove the problem of excessive short-circuit currentImprove the problem of exceeding the standardElectric power transfer ac networkReactive power adjustment/elimination/compensationTransient statePower grid
The invention discloses a converter station near-zone short-circuit current control method and system. The method comprises the steps: building an electromagnetic transient simulation model of a voltage sourced converter (VSC) connected to a power grid near zone, and initially setting a station-level control mode of a flexible DC power transmission system; judging whether the bus short-circuit current of the VSC near zone station is greater than a preset short-circuit current threshold value under the current control mode, and obtaining a first judgment result; and when the first judgment result indicates that the first judgment result is greater than the preset short-circuit current threshold value, switching the control mode of the reactive power of the VSC near region into a constant reactive power 0Mvar. According to the invention, the reactive power control mode of VSC is adjusted, the contribution current amplitude/phase during the short-circuit fault of the VSC is changed, the near-region short-circuit current level of the converter station is suppressed by changing the vector superposition relationship between the flexible direct-current contribution current component and the alternating-current short-circuit current component, and the problem that the near-region short-circuit current of the converter station exceeds the standard after the converter station is flexiblyand directly connected into a power grid is solved.

Universal type automatic sorting machine for multispectral imaging mixed plastics

The invention discloses a universal type automatic sorting machine for multispectral imaging mixed plastics. The universal type automatic sorting machine comprises a machine frame, a speed building module, a multispectral imaging recognition module, a sorting execution module and a data collection computing control module. The speed building module is used for enabling detected plastic parts to reach the designed speed and enabling the plastic parts to obtain the enough speed when leaving the speed building module so as to build a parabolic flight path needed in the design; the multispectral imaging recognition module is arranged above the speed building module and can recognize all common plastics; the sorting execution module is used for separating out the target plastic parts by damaging the flight path of the plastic parts in the plastic flying process; the data collection computing control module is the neural center of the whole automatic sorting machine and is responsible for the cooperative work of the speed building module, the multispectral imaging recognition module and the sorting execution module, so that the operations such as accelerating, recognizing and selecting the detected plastic parts are completed; and the accuracy and efficiency are high.
