Sintering machine ignition furnace hot air combustion-supporting system

Abstract

The invention relates to a sintering machine ignition furnace hot air combustion-supporting system, and belongs to the technical field of ignition furnace combustion supporting. The sintering machineignition furnace hot air combustion-supporting system comprises a rack, a sintering machine body and an ignition furnace, the ignition furnace communicates with a combustion-supporting air pipe, the tail of the sintering machine body is provided with a discharging port, an air suction cover is arranged on the rack, the air suction cover is located right above the discharging port, an air suction pipe is arranged between the air suction cover and the combustion-supporting air pipe in a communicating manner, and an air blower which communicates with the air suction pipe is arranged on the rack.According to the sintering machine ignition furnace hot air combustion-supporting system, sintered materials generated after the sintering machine body works are discharged through the discharging port, and due to the fact that the temperature of the sintered materials is very high, the temperature of air near the discharging port is high; and during working, the air blower works, so that the airnear the discharging port is sucked into the air suction cover, introduced into the combustion-supporting air pipe through the air suction pipe and finally led into the ignition furnace, the ignitiontemperature is increased to the maximum extent, the gas consumption of the ignition furnace is reduced, and the fuel is saved.

Description

technical field [0001] The invention relates to the technical field of combustion-supporting ignition furnaces, in particular to a hot air combustion-supporting system for ignition furnaces of sintering machines. Background technique [0002] The ignition fuel of existing ignition furnaces is usually blast furnace gas. In recent years, gas with high calorific value has been used instead of gas with low calorific value to achieve the purpose of saving energy and reducing consumption. Both in theory and in actual production, good gas-saving effects have been achieved. [0003] The Chinese patent with application publication number CN106440810A discloses a sintering machine, which includes a sintering trolley for the sintering raw material bed including solid fuel to move on the sintering trolley; an igniter located at the front above the sintering trolley; Windshield, located at the rear above the sintering trolley; bellows, located under the sintering trolley, used to collec...

AI Technical Summary

Problems solved by technology

[0004] The existing technical solutions above have the following defects. When the igniter is working, air needs to be introduced to support combustion, and the temperature of the combustion-supporting air is different, which has an impact on sintering ignition and fuel utilization. The higher the air temperature, the better the ignition effect. Well, less fuel consumption

However, when the igniter works, if the outside air is directly used as the combustion-supporting air, the air temperature will be lower, the ignition and combustion-supporting effect will be poor, and the fuel consumption will be large; if the air is preheated in advance, it will undoubtedly increase energy consumption; there is a certain defect
