A Complete Guide to Tubular Chain Conveyors: Core Equipment for Enclosed Conveying in Dry Desulfurization Systems

In dry desulfurization, powder processing, environmental treatment, chemicals and building materials, the enclosed, stable and highly efficient conveying of powder materials is critical to keeping an entire production line running continuously. With its unique conveying advantages, the tubular chain conveyor completely solves the problems of traditional belt, screw and bucket elevators in powder conveying - heavy dust, poor sealing, frequent blockages, high energy consumption and layout constraints - making it the standard conveying equipment for dry desulfurization systems, powder grinding lines and environmental material handling.

For dry desulfurization processes, the tubular chain conveyor is mainly responsible for the enclosed conveying of ultrafine desulfurization agents such as sodium bicarbonate, limestone powder and magnesium hydroxide, linking the desulfurization agent mill with the injection system and providing a seamless connection from powder discharge to desulfurization dosing. Unlike conventional conveyors, it uses a chain driving discs that circulate inside an enclosed pipe, so there is no dust emission and no material spillage throughout the process. It meets the dust-free and standardized production requirements of industrial environmental protection sites and is an indispensable conveying hub in the entire dry desulfurization system.

As industrial environmental controls become ever stricter, the environmental requirements for powder conveying have risen accordingly, and traditional open conveyors can no longer meet site regulations. With core advantages such as a fully enclosed structure, multiple inlet and outlet points, flexible spatial layout, low wear and low energy consumption, and suitability for ultrafine powders, Peman tubular chain conveyors are rapidly replacing conventional equipment. They are widely used in coal-fired power plants, waste incineration, steel and coking, cement and building materials, fine chemicals and many other industries, and are especially suited to demanding applications such as dry desulfurization that require extremely high sealing and stability.

A qualified tubular chain conveyor can run continuously and stably for 24 hours, with no material segregation and no powder agglomeration during conveying, and with no loss of desulfurization agent and no effect on powder fineness. It both ensures uniform feeding to the desulfurization system and eliminates dust pollution, combining practicality with environmental performance, making it the preferred choice in the field of enclosed industrial powder conveying.
