The present invention relates to an
environmentally friendly lamp holder
brick, wherein a gas channel is arranged in the middle of the lamp holder
brick, and a plurality of small
waste gas channels are arranged on the periphery of the gas channel; one end of the small
waste gas channel is connected to the gas channel, and the other end passes through the lamp holder
brick, and the outer end opening of the small
waste gas channel is a waste gas suction port, the inner end opening is a waste gas outlet, the bottom end opening of the gas channel is a gas inlet, and the top end opening is a
mixed gas outlet. The present invention arranges a small waste gas channel on the lamp holder brick, and the negative pressure generated when the
coke oven gas passes through the gas channel can inhale the waste gas around the lamp holder brick, and the waste gas is mixed with the
coke oven gas and enters the vertical fire channel from the
mixed gas outlet, that is, the waste gas and the
coke oven gas are mixed in advance in the lamp holder brick, thereby further reducing the generation of
nitrogen oxides.
