Drying device for the production of honeycomb ceramic body SCR denitration catalyst

Abstract

The invention discloses a drying device for the production of honeycomb ceramic body SCR denitration catalyst. An external casing is formed by a steel structure skeleton and a sealed heat insulation housing; at one side of the external body is provided with a sealed roller-blind door and an access door; the external casing is provided with a three-dimensional dynamic air supply system; two sides of the three-dimensional dynamic air supply system are provided with drying trolleys; the top of the external casing is provided with a waste discharging pipe, a mixed air pipe, a return air pipe and a fresh air pipe; the mixed air pipe is installed at the rear of the waste discharge pipe; the return air pipe is connected with the fresh air pipe; the mixed air pipe is connected with the return air pipe. By means of the device of the invention, drying period is shortened; the output in unit time is increased and energy consumption is greatly reduced; by means of the three-dimension dynamic air supply mode, the product qualified rate is greatly increased which reaches 95% and above.

Description

technical field [0001] The invention relates to the field of heat treatment equipment, in particular to a drying equipment used for the production of honeycomb ceramic SCR denitration catalysts. Background technique [0002] With the development of our country's economy, the environmental problems caused by energy consumption are becoming more and more serious. Following flue gas desulfurization, the control of nitrogen oxides is an objective requirement for the sustainable development of the national economy and environmental protection. In order to prevent and control the pollution caused by nitrogen oxide emissions from thermal power plants, improve the quality of the atmospheric environment, and protect the ecological environment, the national environmental protection department has successively issued a series of policies and regulations. Although most coal-fired smoke exhaust enterprises have installed flue gas denitrification systems, and the output of denitrificatio...
