Abstract

The invention discloses a honeycomb type SCR denitration catalyst calcining furnace and a method for drying an SCR denitration catalyst. The honeycomb type SCR denitration catalyst calcining furnace comprises a furnace body, a conveying device and a heating device. The conveying device comprises a feeding platform, a conveying platform and a discharging platform. The conveying device further comprises a net belt operating on the feeding platform, the conveying platform and the discharging platform in a revolving mode. The heating device is an infrared quartz heating pipe arranged inside the furnace body. The tail end of the furnace body is provided with a cooling area which is provided with a heat exchanging pipe. The heat exchanging pipe is connected with a heat pumping draught fan. The two sides of the net belt are provided with automatic skew adjustment devices comprising guiding wheels. The drying method comprises the warming section I, the sintering section I, the warming section II, the sintering section II and the cooling section. The calcining furnace is economical, durable, good in heat preservation effect and high in automation degree and saves energy consumption, the number of the fractured sintered products is small, and the quality of the products is high.

Description

technical field [0001] The invention belongs to the field of SCR denitration catalyst production, and in particular relates to a calciner for producing a honeycomb SCR denitration catalyst and a drying method thereof. Background technique [0002] Due to the rapid development of human activities and economy, my country's environment has been severely damaged, and extreme weather has increased significantly, posing a serious threat to people's lives and property, causing heavy losses to the country, and hindering the sustainable development of the national economy. The country has also paid a huge price for environmental governance. [0003] my country's current total nitrogen oxide emissions have exceeded 18 million tons. If no effective control measures are taken, China's nitrogen oxide emissions will continue to increase in the next fifteen years, and may reach more than 30 million tons by 2020. my country is a large coal-burning country, and coal-fired power plants are t...
