Comprehensive utilization device for activated coke regeneration waste heat

Abstract

The utility model discloses a comprehensive utilization device of activated coke regeneration waste heat, belongs to the technical field of activated coke regeneration equipment, and is used for comprehensively utilizing waste heat generated in the activated coke dry desulfurization and denitrification regeneration process. The technical scheme is as follows: the cooling section cooling flue gas outlet pipeline of a regeneration tower is connected with a heating furnace combustion-supporting gas inlet, a heating furnace heating flue gas outlet pipeline and the heat tracing pipeline of the regeneration tower; the heating section hot smoke outlet pipeline of the regeneration tower is connected with the heating furnace hot smoke inlet through a hot smoke fan, a heating furnace hot smoke outlet pipeline is connected with the heating section hot smoke inlet of the regeneration tower, and a heating furnace heating smoke outlet pipeline is connected with a sulfur-rich gas heat tracing pipeline and an ammonia water vaporization smoke inlet pipeline. According to the comprehensive utilization device, the characteristics of the activated coke desulfurization and denitrification process are fully combined, all waste heat generated in the regeneration process can be recycled, the waste heat recycling efficiency is improved, energy consumption is reduced, and the production cost of enterprises is reduced.

Description

technical field [0001] The invention relates to a device for comprehensively utilizing waste heat generated in the regeneration process of active coke dry desulfurization and denitrification, and belongs to the technical field of active coke regeneration equipment. Background technique [0002] The regeneration equipment for activated coke desulfurization and denitrification mainly includes regeneration tower, heating furnace, combustion-supporting fan, cooling fan, hot smoke fan, sulfur-enriched fan and other equipment. The main function of the regeneration tower is to remove the adsorbed SO 2 Activated carbon such as pollutants is regenerated by heating, so that it can recover and remove SO 2 , NOx and other pollutants. The regeneration tower is mainly divided into a charging section, a heating section, a degassing section, a cooling section, and a discharging section. Its working principle is to heat the air to 500-600°C by burning natural gas, coke oven gas, blast furna...
