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.

Embodiment

[0030] Such as figure 1 As shown, the circulating drying system for drying the denitration agent by using natural gas heat source in the present invention includes a drying chamber 10, and the circulating drying system includes: an air guide module 20, a heat exchange module 40, a heating module 30, a measurement module 50, The air return module 60 and the air outlet module 70; the air guide module 20 is used to distribute the air volume blown into the drying chamber 10 by the air outlet; since the natural gas itself contains some impurities, it will form particles after burning, if the hot air is used directly To dry the base material, these particles may be left on the surface of the product and become an unqualified product. Therefore, the heat exchanger in the heat exchange module 40 is used to heat the gas with gas, and all the high-temperature gas after natural gas combustion is heat-exchanged The module replaces heat energy; the heating module 30 is used to fully burn n...

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...
