Novel energy-saving environmentally friendly dry coke quenching equipment

Abstract

The invention discloses novel energy-saving environmentally friendly dry coke quenching equipment. A dry coke quenching furnace communicates with a first air inlet tube and a first air outlet tube, the first air outlet tube extends into a sewage tank and is connected with a flow distribution three-way valve, the flow distribution three-way valve is connected with a second air inlet tube and is connected with a third air inlet tube through a filter element flange, the second air inlet tube extends into a cooling tank, the cooling tank communicates with a second air outlet tube, a third air inlet tube and the second air outlet tube are connected with a flow combination three-way valve, and the flow combination three-way valve and the first air inlet tube are connected with a first air blower; the sewage tank communicates with a fourth air outlet tube, the middle of the fourth air outlet tube is a condensation tube section and communicates with a water storage tank, the water storage tankis connected with a first water outlet tube, and the first water outlet tube extends into the cooling tank; a pump is mounted at the bottom of the cooling tank and is connected with a second water outlet tube,, and the second water outlet tube extends into the sewage tank; and liquid-level meters are further arranged in the sewage tank and the cooling tank. In the technical scheme, an internal circulation type inert gas cooling system is formed, a function of circulating cooling water for heat exchange is fulfilled, a dust removal function can be fulfilled, and the novel energy-saving environmentally friendly dry coke quenching equipment is environmentally friendly and energy-saving.

Description

technical field [0001] The invention relates to the technical field of CDQ production, in particular to a novel energy-saving and environment-friendly CDQ equipment. Background technique [0002] Coke dry quenching is relative to wet coke quenching. Dry coke quenching is a coke quenching method that uses inert gas to cool red coke in an oxygen-free environment. During the CDQ process, red coke is loaded from the top of the CDQ furnace, low-temperature inert gas is blown into the red coke layer in the cooling section of the CDQ furnace by a circulating fan, and the cooled coke is discharged from the bottom of the CDQ furnace; red coke is absorbed After latent heat, the inert circulating gas whose temperature has risen is discharged from the CDQ oven, it goes through a heat exchange system, and the high-temperature inert gas is cooled and dedusted, and then sent by the blower to the CDQ oven for circulating operation. [0003] The current heat exchange system is usually a boi...

Problems solved by technology

However, this method cannot achieve a good dust removal effect. The red coke dust is easy to circulate with the inert gas in the circulating air duct, or it will be sent out of the circulating air duct during the dust removal process to pollute the environment.
