Embodiment Construction

[0027] in accordance with figure 1 The specific implementation of the ignition device of the lead-zinc material sintering belt sintering machine of the present invention will be described below.

[0028] A belt type sintering machine ignition device, such as figure 1 As shown, it is mainly composed of a fuel distribution chamber, a primary air distribution chamber, a fuel ejection branch pipe, a primary air ejection branch pipe, a secondary air distribution chamber, a secondary air ejection channel, a combustion chamber, and the like. The fuel distribution chamber is made of seamless steel pipes and is connected with a fuel inlet and multiple fuel ejection branches. The fuel distribution chamber is sheathed in the primary air distribution chamber. The primary air distribution chamber is made of seamless steel pipes, connected with one primary air inlet, multiple (the same number of fuel ejection branch pipes) primary air ejection branch pipes, and the primary air ejection branch ...

Abstract

The invention discloses an ignition device for a belt type sintering machine. The ignition device includes a fuel distribution chamber, the feed port of which communicates with the fuel inlet, and the discharge end of the fuel distribution chamber communicates with the inner cavity of the combustion chamber; the primary air distribution chamber, whose intake end communicates with the primary air inlet, the The outlet end of the primary air distribution chamber communicates with the inner chamber of the combustion chamber; the inlet end of the secondary air distribution chamber communicates with the secondary air inlet, and the outlet end of the secondary air distribution chamber communicates with the inner chamber of the combustion chamber; The outlet end of the fuel injection branch pipe merges with the outlet end of the primary air injection branch pipe, and after the air in the secondary air injection channel is ejected, it merges with the beam flame formed by the fuel combustion in the fuel injection branch pipe and enters the combustion chamber. The cavities meet to form a ribbon flame. The invention realizes strip ignition, short ignition time and less fuel consumption.

Description

Technical field [0001] The invention relates to an ignition device for a belt sintering machine, belonging to the technical field of combustion devices, and is particularly suitable as an ignition device for a lead-zinc material sintering and roasting belt sintering machine. Background technique [0002] Lead-zinc closed blast furnace smelting technology has unique advantages for smelting lead and zinc mixtures. One of the main links is the sintering and roasting of lead-zinc mixtures. The sintering and roasting of the lead-zinc mixture is completed in a belt sintering machine, and the ignition device of the sintering machine plays the role of making the material ignite. At present, in our country's manufacturers of lead-zinc closed blast furnaces for smelting lead and zinc, the ignition device of the belt sintering machine is a small sleeve type burner on the base of the furnace body. The burners are generally two rows, 6 in each row. [0003] The structure of the ignition device...
