A multi-directional movable underwater excavation cabin is composed of a dangerous goods excavation work ship buoyancy hull, an underwater excavation work cabin, an underwater excavation work cabin lifting device, an underwater excavation work cabin lifting guide structure, a compressed air pipeline, a crane, an underwater camera, an internal pressure monitor, an external water pressure monitor and the like. The underwater dangerous goods excavation work cabin of the present application is installed on a special work ship which can sail and position itself, and the underwater excavation cabin lifting device installed on the ship is used to place the underwater excavation work cabin into water until the bottom of the underwater cabin contacts the river bottom. Compressed air is injected into the underwater cabin through the compressed air system on the ship, and when the pressure of the compressed air is greater than the pressure outside the excavation cabin, the water in the underwater cabin can be pressed out of the excavation cabin, so that the river bottom in the covered area of the excavation cabin is in a water-free state.

The utility model belongs to the field of treatment devices, and particularly relates to an efficient and energy-saving sludge and waste incineration dry distillation device which comprises a conveying and filtering assembly. The conveying and filtering assembly is provided with a fixing frame, a stepping motor is fixedly installed on one side of the fixing frame, a transmission roller is fixedly installed at the output end of the stepping motor, and the periphery of the transmission roller is in transmission connection with a conveying belt. After sludge is placed in an inner cavity of a delivery bin, a stepping motor is driven to drive a transmission roller to rotate, then a conveying belt is driven, the conveying belt is limited by a plurality of limiting rollers and synchronously rotates along with the transmission roller, the sludge is conveyed to a grinding roller, sludge dewatering is achieved by means of tension of the grinding roller, and dewatered sludge cakes fall into a collecting tank through a falling bin to be stored and incinerated. And the torque motor is driven to drive the auger to rotate, mud cakes in the collecting tank are conveyed to the incineration bin through the output pipe to be incinerated, the function of separated conveying is achieved, the problem that sludge needs to be conveyed manually is solved, and the adaptability in use is improved.

The present application belongs to the technical field of multi-effect rectification, and relates to a horizontal-tube falling-film multi-effect rectification system and process. The horizontal-tube falling-film multi-effect rectification system comprises, in sequence, a multi-effect evaporation chamber, a multi-effect rectification tower, a multi-effect circulating transfer pump, a multi-effect reflux tank, a multi-effect reflux pump and a one-effect condenser.
