Steel slag cooling flue gas treatment machine

Abstract

The invention discloses a steel slag cooling flue gas treatment machine which comprises a machine body, a flue gas exhaust channel with an opening in the upper side is formed in the machine body, a funnel-shaped falling space is formed in the lower side wall of the flue gas exhaust channel in a communicating mode, and a passing space with a downward opening is formed in a small opening in the lower side of the falling space in a communicating mode; an air inlet pipeline is arranged on the right side wall of the passing space in a communicating mode, the air inlet pipeline extends rightwards toenter the external space, the air inlet pipeline is connected with the flue gas input end, filtering of the steel slag cooling flue gas is achieved, and when residues in the flue gas block the filterscreen, the filter screen can be cleaned; the situation that the service life of the machine is shortened due to blockage of the filter screen is avoided, the working intensity of manual maintenanceof the machine is reduced due to the self-cleaning effect of the device, the loss of human resources is reduced, and the maintenance work operation is simple.

Description

technical field [0001] The invention belongs to the field of steelmaking, in particular to a steel slag cooling flue gas processing machine. Background technique [0002] The current environmental protection treatment method for liquid steel slag in steelmaking plants in the market has the following problems in the operation process: because the traditional environmental protection treatment method for liquid steel slag in steelmaking plants needs to cool down the steel slag before crushing the steel slag, so that the steel slag hardens, and the steel slag is hardened. During the process, a large amount of flue gas will be generated, and some treatment methods do not effectively control the flue gas, and the flue gas is directly discharged into the atmosphere, causing environmental pollution. At the same time, some flue gas filtering mechanisms are likely to cause A large area of ​​filter holes is blocked, so that the service life of the flue gas filter mechanism cannot be g...

[0002] The current environmental protection treatment method for liquid steel slag in steelmaking plants in the market has the following problems in the operation process: because the traditional environmental protection treatment method for liquid steel slag in steelmaking plants needs to cool down the steel slag before crushing the steel slag, so that the steel slag hardens, and the steel slag is hardened. During the process, a large amount of flue gas will be generated, and some treatment methods do not effectively control the flue gas, and the flue gas is directly discharged into the atmosphere, causing environmental pollution. At the same time, some flue gas filtering mechanisms are likely to cause The filter holes are blocked in a large area, so that the service life of the flue gas filter mechanism cannot be guaranteed, so it is urgent to design a flue gas treatment machine that prevents the filter mechanism from clogging
