DESCRIPTION

Product description/purpose/applicable people

The capture hood consists of a fully enclosed hood, an internal suction port, and a movable door on the top. It collects 95% of the smoke generated when the blast furnace taps iron, opens or blocks the iron mouth. In order to later inspect the opening machine or mud gun machine, a movable door is installed on the top of the closed hood to ensure that normal maintenance is not restricted. The fully enclosed hood at the iron mouth can not only capture the smoke generated during normal production, but also ensure that the smoke is temporarily stored in the hood in the event of a large blowout of the blast furnace without overflowing to the outside of the hood and affecting the environment in the workshop. The capture hood uses thermal insulation materials to withstand molten iron splashing (temperature > 1500℃) and slag erosion, reduce the outer surface temperature of the hood, and ensure the life of the equipment and the safety of personnel.



Product Parameters

According to the volume of the blast furnace and the size of the blast furnace iron-casting site platform, the blast furnace iron-casting outlet capture hood is designed as a fully enclosed hood, which fully seals the process of opening and blocking the iron-casting outlet and collects 95% of the flue gas generated during the opening and blocking of the iron-casting outlet.



Product Features/Advantages

It does not affect production, has a high smoke capture rate, can store a large amount of smoke in a short period of time, plays a certain protective role for workers, and has a good noise reduction effect.

Fume extraction system (FES) INDUSTRY KNOWLEDGE

What are the core components and key functions of a blast furnace taphole capture hood?

The design of a blast furnace taphole hood directly impacts flue gas capture efficiency and production safety. Its core components include a fully enclosed hood, internal air intakes, and a top movable door. The fully enclosed hood is the foundation for fume capture, creating a relatively closed space around the taphole. Combined with the internal air intakes, it efficiently collects fumes generated during tapping, opening, or blocking the taphole, achieving a capture rate of up to 95%, reducing the spread of fume into the workshop environment. The top movable door design fully considers the needs of ongoing equipment maintenance. When inspecting the opener or blasting machine, the door can be opened, ensuring smooth maintenance without being hindered by the hood's closed nature. The fully enclosed hood also provides emergency response capabilities. In the event of large-scale iron blowout in the blast furnace, the hood can temporarily trap fume, preventing it from overflowing and impacting the workshop environment. Furthermore, the hood is constructed of insulating material, which protects against molten iron splash and slag erosion, while also reducing the hood's outer surface temperature, ensuring equipment life and the safety of on-site workers.

What key factors should be considered when designing a custom blast furnace taphole capture hood?

This involves considering various factors, including specific blast furnace parameters and production conditions. Firstly, production parameters such as the blast furnace's tapping rate and frequency affect the amount and rate of flue gas generation, which in turn determine the size of the hood, the number of air intakes, and the suction power.
Secondly, the spatial layout of the site is also a key consideration. The size and installation location of the hood must be compatible with the equipment surrounding the taphole (such as the opener and blast gun) to ensure optimal flue gas capture without disrupting normal production operations.
Furthermore, material selection is crucial. Because the hood operates in a harsh environment, withstanding high temperatures, molten iron splash, and slag erosion, insulation materials that are heat-resistant, wear-resistant, and corrosion-resistant are essential to ensure durability and safety. The design of the top movable door must balance sealing and easy opening to ensure flexible operation during maintenance.
