Air Distribution Bed Material System for Dry Cooling and Conveying of High Temperature Slag

Abstract

The invention provides an air distribution bed material system for high-temperature slab dry cooling and conveying. The system comprises an air chamber (9) at the bottom, the air chamber (9) can be communicated with the outside to introduce natural air or convey needed air through a draught fan, and a tank type air distribution system is arranged on the top of the air chamber (9). The tank type air distribution system comprises an air distribution plate (4), a plurality of air inlets are formed in the lower side of the air distribution plate (4), maze type air distribution units (1) are fixed to the air distribution plate (4), a U-type plate (3) is correspondingly arranged on a ventilation port formed by every two adjacent maze type air distribution units (1), a U-type opening of every U-type plate (3) covers the corresponding ventilation port formed by two adjacent maze type air distribution units (1), and a gap is reserved between every U-type plate (3) and two adjacent maze type air distribution units (1) to form an air flue. Thus, existing defects are overcome, and combustion of fuel in a boiler can be promoted more efficiently.

Description

technical field [0001] The invention relates to a high-temperature slag dry-type cooling and conveying air-distributing bed material system, in particular to a new high-temperature slag dry-type cooling and conveying air-distributing bed material system suitable for power stations, cement plants and steel plants. Background technique [0002] At present, the equipment for the treatment of high-temperature dry slag in the world is mainly conveyed by steel belts and cooled by natural wind. This kind of equipment has the following disadvantages: [0003] 1. The high-temperature slag falls on the steel belt and is taken away, and some high-temperature slag is not fully cooled at the exit, causing damage to the steel belt to a certain extent. [0004] 2. The structure of the steel strip is complicated and weak, and the thermal fatigue of the steel plate is serious. [0005] 3. This kind of structure is limited by the design idea, the cost is high, the reliability is low, and the...

AI Technical Summary

Problems solved by technology

[0003] 1. The high-temperature slag falls on the steel belt and is taken away, and some high-temperature slag at the exit has not been fully cooled, causing a certain degree of damage to the steel belt

[0004] 2. The structure of the steel strip is complicated and weak, and the thermal fatigue of the steel plate is serious

[0005] 3. This structure is limited by the design idea, the cost is high, the reliability is low, and the failure rate is high

[0007] However, in this structure, for uniform cooling, each unit usually needs to be equipped with a fan, and each cooling unit needs a constant air input rate input, the input volume must be displayed on the central control panel, the fan motor speed or The adjustment of the fan inlet actuator must be controlled by the adjuster, and the adjuster must also receive the signal from the airflow meter on the fan inlet pipe to keep the airflow input constant. The structure is relatively complicated, the cost is very high, and the failure higher rate

[0008] Therefore, there are great obstacles in practical application, which seriously affects its popularization and use.
