This utility model discloses a dust collection device for a pipeline dust removal outlet, belonging to the field of dust collection device technology. It includes a housing fixed to the lower end of a pipeline, with a slag inlet connected to the pipeline at the upper end of the housing. It also includes a spraying mechanism and a negative pressure vacuum cleaner. The spraying mechanism is connected to one side of the housing, and the negative pressure vacuum cleaner is fixed to the upper end of the housing. The upper end of the housing has several suction ports, and the negative pressure vacuum cleaner is interconnected with these ports. A slag outlet is located on the other side of the housing. Advantages of this utility model: In this embodiment, the spraying mechanism uses a water pump to drive water from a nozzle towards the area below the slag outlet inside the pipeline within the housing, thus preventing dust from adhering to water molecules and settling, effectively improving dust settling efficiency. The negative pressure vacuum cleaner can vacuum up unsettled dust and simultaneously absorb mist generated within the housing, further improving the dust removal effect.

This utility model discloses a dust removal and cooling device for high-dust, high-concentration, ultra-high-temperature hydrogen gas, used for dust removal and cooling of the cracked gas produced by methane cracking for hydrogen production. It includes a dust collector and a cooling device. The dust collector comprises a gravity dust collection box and a water tank, with the gravity dust collection box nested within the water tank. The gravity dust collection box is used to deposit carbon powder in the cracked gas and has an ash hopper at its bottom. The water tank cools the gas entering the gravity dust collection box by supplying circulating water. The cooling device cools the cracked gas after dust removal by supplying circulating water. This dust removal and cooling device effectively solves the technical problems existing in the current methane cracking for hydrogen production process, such as difficulty in carbon-hydrogen separation under high dust, high concentration, and ultra-high temperature conditions, carbon powder blockage during hydrogen cooling, and difficulty in collecting carbon powder after high-temperature dust removal. The cracked gas undergoes subsequent cooling treatment only after a large amount of carbon powder is removed and after initial cooling and deceleration, which reduces the risk of blockage in the cooler.

The present application relates to the technical fields of deep-sea mining, and especially relates to a deep-sea mining hydraulic conveying relay station and a hydraulic lifting mining system. The deep-sea mining hydraulic conveying relay station comprises a stock bin and a feeding pipe. The stock bin comprises an upper stock bin and a lower stock bin. The upper stock bin is provided with a fixed baffle. A sliding baffle is arranged between the upper stock bin and the lower stock bin. The sliding baffle and the fixed baffle separate the stock bin into independent injection space and settling space. The sliding baffle is in sliding connection with the stock bin and can rotate around the central axis of the stock bin, so that the injection space and the settling space are alternately changed. The feeding pipe comprises injection pipes respectively connected to the injection space and the settling space. The injection pipe connected to the injection space is in an open state. The present application can reduce the blockage and ore overflow in the stock bin, realize continuous and uniform feeding, and has low requirements for the structure pressure resistance and is environment-friendly.

This utility model belongs to the field of grinding and dust removal technology, specifically relating to an explosion-proof wet dust collector. It includes a dust removal chamber, with a mounting frame on the top of the chamber to fix a fan. The fan's inlet connects to the inside of the chamber, and its outlet connects to the exhaust port. A dust extraction pipe is installed on the side wall of the chamber, passing through a water extraction pipe and connecting to a circulating water pump. The bottom, top, and middle sections of the chamber are equipped with bottom, upper, and middle partitions at an angle. A liquid seal is formed by submerging the bottom partition by 3mm to 5mm, which, combined with the oblique and reverse airflow channels formed by the multiple partitions, promotes thorough mixing of dust and liquid and condensation of water vapor. The circulating water pump delivers the liquid through a pipe to the nozzle at the inlet of the dust extraction pipe, flushing the inner wall to prevent dust accumulation. This design combines explosion-proof performance with high-efficiency dust removal capabilities, has a compact structure, and low cost, making it suitable for small-scale operating environments such as small and medium-sized processing plants.

This invention discloses a method for identifying ozone pollution layers in the low-altitude atmosphere and a method for rapid ozone deposition in the low-altitude atmosphere. The ozone pollution layer identification method achieves precise spatial positioning of the pollution layer through the synergy of a localized ozone exceedance risk threshold and lidar three-dimensional scanning. By combining precursor concentration data, ozone photochemical process correlation parameters, and observation-driven models to quantify regional transport contributions, it effectively identifies ozone pollution accumulation areas in the upper boundary layer, overcoming the limitations of ground monitoring stations and satellite remote sensing in terms of vertical resolution. The rapid ozone deposition method in the low-altitude atmosphere addresses the problems of difficult photochemical reaction control, insufficient intervention in the upper-altitude pollution layer, and weak suppression of cross-regional transport faced by existing ozone control technologies. Through the synergistic effect of physical disturbance and deposition, it accelerates turbulent diffusion, achieving large-scale, strongly disturbed ozone pollution control and reducing the height of the pollution layer and the impact of cross-regional transport.
