Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] see figure 1 figure 2 , The technical solution adopted in the present invention is: a new type of low-calorific-value associated gas and carbon black burnout (activated carbon carbonization furnace pyrolysis gas and activation furnace associated gas) low NOx burner. Low calorific value gas inlet 1, ignition chamber 2, primary air inlet 3, combustion-supporting device 4, swirl channel regenerative burner 5, swirl burn-off air 6, burn-out chamber or furnace 7, recessed heat-accumulating burner 8. The extremely low calorific value gas produced in the activated carbon manufacturing process enters from the low calorific value gas inlet 1, and the primary air entering the primary air inlet 3 and the pyrolysis gas generated by the raw coal in the combustion supporting device 4 enter the cyclone after being ignited in the ignition chamber 2. The heat storag...

Abstract

The invention discloses a low NOx burner for resource utilization of ultra-low heating value associated gases and carbon black burnout. The Low NOx burner for resource utilization of ultra-low heatingvalue associated gases and carbon black burnout comprises a smoke inlet for the entry of the ultra-low heating value gases generated in the activated carbon manufacturing process, wherein the outputend of the smoke inlet is connected to a pilot combustion chamber; a primary air inlet is formed in the pilot combustion chamber; and low heating value gases burning in the pilot combustion chamber are completely burned in a concave heat gathering combustion chamber and a hearth through the cooperation of a vortex channel heat storage burner and over firing air fed by an over firing air inlet. Thelow NOx burner realizes the integrated treatment of industrial ultra-low heating value associated gas combustion, carbon black elimination and low NOx combustion, effectively utilizes the heat of theultra-low heating value gases, greatly improves the utilization efficiency of energy sources, can provide heat for subsequent enterprise transformations such as smoke whitening or heating transformation, and eliminates environmental pollution such as carbon black.

Description

technical field [0001] The invention relates to chemical manufacturing enterprises such as activated carbon and the technical field of energy conservation and environmental protection, and in particular to a burnout low NOx burner with extremely low calorific value associated gas and carbon black. Background technique [0002] The preparation of activated carbon from raw coal generally requires two steps of treatment. One is carbonization treatment to reduce the non-carbon components in the coal, that is, the raw coal is isolated from the air for high-temperature pyrolysis, and the other is activation treatment to make the carbonized coal gasify with water vapor to produce Well-developed void structure. A large amount of carbonized pyrolysis gas and activated associated gas will be produced during the carbonization and activation process. The calorific value of these gases is extremely low, about 4% of the calorific value of methane. The main component of combustible gas is...
