This invention discloses a method for processing spinning, printing and dyeing waste water by a coal-water slurry production technology including a step of filtering spinning, printing and dyeing waste water, a step of determining the mixture ratio among desulfurizer, dispersant, clean water and waste water, a step of mixing slurrying, a step of stabilizing the slurry and a step of aging and storing coal-water slurries.

The invention provides a semi-submersible type floating fan base and a floating fan. The floating fan base comprises at least three stand columns, a stand column connecting structure and a supporting stand column, wherein the stand column connecting structure is connected with the lower ends of the stand columns to integrate the stand columns and the stand column connecting structure into a whole; the supporting stand column is arranged in the center of the floating fan base and used for supporting a tower, a cabin, blades and a wind generating system of the fan; and the cross sectional area of each stand column gradually grows large from a preset position underwater to top. The floating fan comprises the semi-submersible type floating fan base, the tower, the cabin, the wind generating system and the blades, wherein the tower is mounted on the supporting stand column of the semi-submersible type floating fan base; the cabin is mounted on the top of the tower; and the wind generating system and the blades are mounted at the front end of the cabin. According to the semi-submersible type floating fan base, the structure and the movement performance of the floating fan are improved, and production cost and installation cost are reduced.

A cabin door system for an aircraft and an aircraft having the cabin door system are disclosed. The aircraft cabin door system has a cabin door having an outer side and an inner side, a drive device coupled to the cabin door for moving the cabin door into an open position, a first actuation device arranged on the inner side surface of the cabin door, a second actuation device, and an emergency chute unit coupled to the cabin door and having an emergency chute and an actuation mechanism. The emergency chute unit can be moved into an active state, in which opening the cabin door leads to activation of the emergency chute, and an inactive state, in which opening the cabin door does not lead to activation of the emergency chute. The emergency chute unit is in the inactive state when the cabindoor is opened after actuation of the first actuation device. The second actuation device is coupled to the drive device and configured such that the cabin door is opened by the drive device during actuation of the second actuation device. The emergency chute unit is in the active state when the cabin door is opened after actuation of the second actuation device.

A keyless phase angle domain period segmentation method of a reciprocating compressor signal belongs to the technical field of fault diagnosis of a reciprocating compressor. Aiming at the problem that the key phase signal is abnormal or even lost in the actual on-line monitoring of the reciprocating compressor, the fault diagnosis and analysis cannot be carried out, and the whole cycle interception of the signal is completed by mining the effective information inside the signal itself. It includes steps: 1) obtaining vibration signals and converting them into images; 2) determining the size of the interception window; 3) identifying the opening impact of the air valve; 4) calculating the phase of the air valve opening and intercepting the whole cycle signal. The method realizes the whole cycle re-segmentation of the collected compressor original signal without installing the key-phase sensor or the failure of the key-phase sensor. It saves the high cost of key-phase equipment and avoids the failure of the online monitoring system to perform effective diagnosis and the failure of the gas volume control system due to the failure of the monitoring equipment, which effectively improves the reliability of the compressor monitoring and control system.
