Circulating drying system for drying denitrification agent using natural gas heat source

Abstract

The invention discloses a circulation drying system for drying a denitrification agent by using a natural gas heat source, which includes a drying chamber. It is used to distribute the air volume blown into the drying room from the air outlet; the heating module is used to fully burn natural gas to generate CO ) with H ) O, and connected to the heat exchange module to provide a heat source for the heat exchange module; the heat exchange module adopts the method of gas heating gas to exchange all the high-temperature gas after natural gas combustion through the heat exchange module; the measurement module is used to measure the temperature and humidity in the drying room , to monitor the temperature and humidity changes in the room; the return air module is used to return and reheat the hot air in the drying room; the air outlet module is used to send the hot air produced by the heat exchange module into the drying room. Through the air guide module, the drying speed of the catalyst in the drying chamber is consistent, and it is also possible to dry the local area independently and quickly.

Description

technical field [0001] The invention relates to the technical field of drying treatment, in particular to a circulation drying system for drying a denitration agent by utilizing a natural gas heat source. Background technique [0002] Use natural gas as the primary drying heat source, heat the air and then circulate hot air to dry the extruded denitrification catalyst wet billet. Generally speaking, only 20-30°C is required for drying. The self-heating material with titanium dioxide in the composition can generate heat to 90°C. The traditional heating method uses raw coal and heavy oil as fuel. These fuels will produce sulfur dioxide, smoke, carbon dioxide and other harmful substances during the combustion process. Direct combustion heating will affect the quality of the product, pollute the air, and there are potential safety hazards, so only The traditional way of indirect heat exchange is adopted. The way of indirect heat exchange determines that its heat loss is relati...

AI Technical Summary

Problems solved by technology

However, the distribution of the air outlets of the existing circulating fans is uneven, and the desiccant near the air outlets receives more wind force, and the drying speed of the catalyst in the drying chamber is uneven, and local rapid drying of local catalysts in the drying chamber cannot be performed.
