Internal components of a fixed-bed reactor
This product series includes support grates, distributors, quench trays, fouling baskets, inlet distributors, outlet collectors, and more. The products are widely used in hydrogenation reactors, desulfurization reactors, cracking reactors, molecular sieves, sand filters, dryers, and other adsorption systems.
The support grid–catalyst support plate consists of a main beam, a grid, and a V‑shaped wire mesh. Our company can perform structural design and strength analysis for the main beam, the grid, and the wire mesh. The support plates we design and manufacture feature high strength, precise mesh aperture tolerances, light weight, uniform dimensions, and easy installation.
The V‑shaped wire mesh panels are manufactured using advanced welding techniques, resulting in a smooth, even surface and highly precise mesh openings (0.1 ± 0.03 mm), with no false or incomplete welds. The internal partition plates of the grille are laser‑cut and then integrally welded to the mesh and frame via laser cladding, yielding a grille that boasts high strength and excellent sealing performance.
Baffle-type mist eliminators are primarily used in flue‑gas desulfurization, which is why they are also known as desulfurization mist eliminators. These devices feature a simple structure, high capture efficiency for medium‑ and large‑size droplets, relatively low pressure drop, easy flushing, a skid‑off design that facilitates maintenance, and lower overall costs.
A wire‑mesh mist eliminator is a gas–liquid separation device that removes entrained droplets as the gas passes through its mesh pad. It primarily consists of wire‑mesh elements, mesh grids forming mesh modules, and supporting structures that secure these modules. It features easy installation and operation, convenient maintenance, a large contact surface area, and high mist‑removal efficiency.
The outlet collection basket at the bottom of the reactor is designed to support the lower catalyst bed, reduce pressure drop across the bed, and improve the distribution of reactants. Our company has extensive experience in designing and manufacturing outlet collection baskets of various configurations for a wide range of processes.
Soot‑catching basket: A basket constructed from V‑shaped wire mesh tubes, positioned at the top of the catalyst bed in the upper section of the reactor. Together with the ceramic balls on the bed, it filters the feed stream entering the reactor. Our company can manufacture soot‑catching baskets of various designs, characterized by high strength and high precision.
Gas–liquid distributor: A reactor‑flow distributor used in hydrogenation reactors, which is broadly classified into two types—overflow type and suction‑jet type—based on its function. Our company’s distribution plates are manufactured using high‑precision CNC equipment, offering excellent sealing performance and superior flatness, thereby meeting stringent installation and operational requirements.
