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.
