The utility model discloses an air-lift shrimp shell collecting device suitable for a factory circulating water culture pond, which relates to the technical field of aquaculture and comprises an L-shaped water outlet pipe, an air-lift cover is fixedly sleeved at the lower end of the water outlet pipe, an air inlet nozzle is arranged on the side surface of the air-lift cover, an inner pipeline communicated with the water outlet pipe is fixedly mounted in the air-lift cover, and the air inlet nozzle is communicated with the air outlet pipe. A plurality of uniformly distributed air inlet holes are formed in the outer surface of the inner pipeline; the lower end of the inner pipeline is communicated with a lower pipeline, a pot bottom is inserted into the bottom of the lower pipeline, and a step with a hole is arranged at the bottom of the pot bottom. By arranging the water outlet pipe, the inner pipeline and the lower pipeline, a complete gas stripping pipeline can be formed, gas can be supplied to the interior of the pipeline in cooperation with the gas stripping cover and the gas inlet cavity and the gas inlet hole in the gas stripping cover, prawn shells can be extracted through gas stripping, the interior of the whole pipeline is free of obstacles, resistance from a nano aeration pipe in a traditional pipeline is reduced, and the prawn shells float upwards without obstacles; the gas efficiency is improved.

The application provides a high-pressure jet granulation device for slag of a slag gasifier, and belongs to the field of slag granulation.The device comprises a gasifier, a granulation chamber and a jet assembly.The metallurgical slag is input into the gasifier from a feeding port, the gasifier converts the metallurgical slag into coal gas and slag, and the gasifier is provided with a jet pipe which is inserted into the metallurgical slag.The top of the granulation chamber is connected with a slag discharge port, the molten slag falls into the granulation chamber, the bottom of the granulation chamber is provided with a slag discharge port, and the side of the granulation chamber is connected with a gas discharge pipe.The jet assembly sprays high-pressure jets to the molten slag flow, so that the molten slag is converted into granulated slag and high-temperature gas, the granulated slag is discharged from the slag discharge port, and the high-temperature gas is discharged from the gas discharge pipe.The jet assembly sprays high-pressure jets to the molten slag flow, so that the molten slag flow is fully granulated under the impact of the high-pressure jets, the granulated slag is small and uniform in size, the high-pressure jets are rapidly converted into high-temperature gas after being contacted with the high-temperature molten slag flow, and the high-temperature gas is discharged from the gas discharge pipe and can be used through backflow.
