Abstract

The invention relates to a denitration catalyst drying apparatus, comprising a drying oven, a heat exchanger and a connection pipeline. An air inlet of the drying oven is connected with an air blower while an air outlet thereof is connected with the heat exchanger; the heat exchanger is connected with a hot steam pipeline; and the output port of the pipeline is connected with the air blower. The denitration catalyst drying apparatus has the following advantages that: 1) in the denitration catalyst drying apparatus, the hot air is recycled through pipelines, so that circulatory utilization rate of the hot air is improved, production cost of enterprises is reduced and economic benefits of enterprises are improved; 2) temperature devices, pressure detection devices, humidity detection devices and air door adjusting devices are arranged everywhere on the pipelines, thus, the temperature, the pressure and the humidity can be regulated according to practical situation, and the catalyst can be dried optimally.

Description

technical field

[0001] The invention relates to a drying device, in particular to a denitration catalyst drying device. Background technique

[0002] At present, the hot air in the drying section of domestic catalyst companies has not been recycled, and the hot air is directly discharged into the atmosphere after passing through the catalyst, resulting in a large amount of energy consumption. According to the current general drying system, the thermal efficiency is only 17.6%. Based on the production capacity of 22,000 cubic meters per year, the traditional drying method consumes 95,982 MJ of heat energy per day, which is equivalent to 34.74 tons of steam at 175°C. The waste phenomenon is extremely serious. Contents of the invention

[0003] The purpose of the present invention is to provide a denitrification catalyst drying device that realizes hot air recycling in view of the above defects.

[0004] The technical scheme that the present invention adopts for this reason ...
