A scr catalyst drying system

Abstract

The invention relates to an SCR (Selective Catalytic Reduction) catalyst drying system. The SCR catalyst drying system comprises a primary drying kiln and a secondary drying kiln, wherein the secondary drying kiln comprises a kiln body, a steam pipeline, a plurality of variable-frequency controlled axial-flow fans, a humidity control system and two kiln car guiding rails, the head and tail of the kiln body are open, the two kiln car guiding rails parallel to the kiln body are arranged inside the kiln body, and the steam pipeline enters the kiln body from the top of the kiln body and is uniformly distributed inside the kiln body; the variable-frequency controlled axial-flow fans are arranged at the top of the kiln body, so as to dehumidify outwards; the humidity control system comprises a fan and a dehumidifying pipeline and is used for dehumidifying by adopting a fan and dehumidifying pipeline combined method; the primary drying kiln adopts a cyclone, a steam pipeline and vaporized water to control the internal temperature and humidity of the kiln. Products are subjected to uniform heating and humidifying, so that the deformation of the products is greatly lowered, and the problem of poor rate of final products is solved; a kiln car is adopted to convey the products, so that fully-automatic production is effectively realized; the kiln body is made from high-quality steel and stainless steel, thereby being stable and reliable.

Description

technical field [0001] The invention relates to an SCR catalyst drying system. Background technique [0002] SCR catalyst is an important part of the denitrification process. In the production process of SCR catalyst, the primary drying and secondary drying of the catalyst are an important part of product production. It is an important pretreatment process before calcination. The box-type static drying is adopted. The box-type static drying uses a forklift to fork the product into the box-type room, and uses a single small box for secondary drying. The production cost is high, the output is small, it is easy to deform and crack, and it cannot be automated. [0003] The above-mentioned problems are mainly due to the fact that there is no method to streamline and automate the production process and meet the requirements for heating and humidifying the product, so that it is impossible to reduce production costs, increase production and reduce the scrap rate. In order to solve ...
