Precise micropressure control and comprehensive waste gas processing device suitable for atmosphere kiln

Abstract

The invention relates to a precise micropressure control and comprehensive waste gas processing device suitable for an atmosphere kiln. The precise micropressure control and comprehensive waste gas processing device comprises the kiln and further comprises a micropressure control system and a comprehensive waste gas processing system. The micropressure control system comprises a differential pressure type micropressure transmitter, a buffer tank, a relay draught fan and a programmable logic controller. The comprehensive waste gas processing system comprises an electric tar catcher, a spray tower, a condenser and an induced draft fan. The precise micropressure control and comprehensive waste gas processing device solves the problems that the pressure inside the kiln is large in fluctuation, not convenient to adjust, and the like, effectively processes related waste gas discharged by the kiln, conforms to the concept of the circular economy industry, is simple, reliable and feasible on the aspects of micropressure control and waste gas processing, and is suitable for being used and popularized within a large range.

Description

technical field [0001] The invention relates to the production process of the atmosphere kiln, especially a device suitable for the precise control of the micro-pressure of the atmosphere kiln and the comprehensive treatment of waste gas. deal with. Background technique [0002] At present, in the process of sintering some raw materials in industrial atmosphere kilns, it is necessary to ensure extremely low oxygen content and smooth exhaust in order to sinter high-quality products. The higher the pressure in the kiln, the lower the oxygen content and the exhaust The air resistance will be greater, and vice versa. It can be seen that there is a negative correlation between the kiln pressure and the oxygen content, especially the sintering process of lithium iron phosphate. On the one hand, high furnace pressure will also reduce the quality of sintered products. Therefore, in order to ensure a good sintering atmosphere in the kiln, it is necessary to ensure a specific micro...
