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.

Abstract

The invention discloses a dry quenching production device with an internal circulation cooling function. A dry quenching furnace is communicated with a first gas inlet pipe and a first gas outlet pipe; the first gas outlet pipe stretches into a sewage tank and is connected with a shunt three-way valve; the shunt three-way valve is connected with a second gas inlet and is connected with a third gasinlet pipe through a filter element flange; the second gas inlet pipe stretches into a cooling tank; the cooling tank is communicated with the second gas outlet pipe; the third gas inlet pipe and thesecond gas outlet pipe are connected with a combined flow three-way valve; the combined flow three-way valve and the first gas inlet pipe are connected with a first air blower; the sewage tank is communicated with a fourth gas outlet pipe; a condensation pipe section is formed on the middle part of the fourth gas outlet pipe and is communicated with a water storage tank; the water storage tank isconnected with the first water outlet pipe; the first water outlet pipe stretches into the cooling tank; a pump body is arranged at the bottom of the cooling tank; the pump body is connected with thesecond water outlet pipe; the second water outlet pipe stretches into the sewage water tank; and a sealing door is arranged on one side of the sewage tank. In the technical scheme, an internal circulation type inert gas cooling system is formed, the function of circulating cooling water for heat exchange is realized, the dust-removing function can be realized, and environmental friendliness and energy saving are achieved.

Description

technical field [0001] The invention relates to the technical field of CDQ production equipment, in particular to a CDQ production device with an internal circulation cooling function. 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 syst...
