Example Embodiment

[0026] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] As attached figure 1 The CDQ energy-saving emission reduction device of the present invention shown includes a fan connected to the sequential air ducts, a reduction cooler, a dust collector 16 and a waste heat boiler 17, and a fan (not shown in the figure) is placed in front of the reduction cooler. The reduction cooler is divided from top to bottom into a combustion chamber 1, a reduction section 2 and a cooling section 3. Among them, the top of the combustion chamber 1 is provided with a furnace cover 11, and an air inlet 10 is opened on the furnace wall in the lower part of the combustion chamber; There is a gas outlet 15 on the upper furnace wall, which communicates with the dust collector through a gas outlet pipe and further communicates with the waste heat boiler 17; a CO2 inlet 6 is opened on the lower furnace wall of the cooli...

Abstract

The invention provides an energy-saving and emission-reducing device for coke dry quenching and an energy-saving and emission-reducing coking process using same, which can realize energy saving and emission reduction with high efficiency and low cost. The invention has the advantages that the emission of carbon dioxides in flue gas is reduced in the coke quenching process, valuable carbon monoxide is generated, and low-cost feed gas is provided for downstream products to synthesize ammonia, methanol and the like while coke quenching, thereby being a new method for realizing energy saving and emission reduction in the coke production and having excellent industry prospects and wide social benefits.

Description

technical field [0001] The invention relates to the field of coking, in particular to a novel coke dry quenching energy saving and emission reduction device and a coking energy saving and emission reduction process using the device. Background technique [0002] At present, coke dry quenching technology (CDQ, Coke Dry Quinching) is a technology that uses low-temperature inert gas (circulation) to exchange heat with red coke in a CDQ furnace, thereby cooling red coke. Generally speaking, the device used for CDQ process consists of red coke loading device, cold coke discharge device, CDQ furnace, gas circulation equipment, waste heat boiler and other auxiliary supporting facilities. The cooling medium is generally nitrogen, and the gas circulation equipment blows it into the CDQ furnace. The nitrogen gas takes away the sensible heat of the coke through heat exchange. The high-temperature nitrogen gas at the outlet of the CDQ furnace enters the waste heat boiler after dust remo...
