Waste recycling environment-friendly metallurgical furnace control method and system

Abstract

According to the waste recycling environment-friendly metallurgical furnace control method, and accurate and automatic control over a smelting furnace can be achieved by the waste recycling environment-friendly metallurgical furnace control method on the basis of real-time parameter changes. According to the technical scheme, the temperature of a circulating cooling water outlet of a smelting furnace jacket and an automatic regulating valve of a furnace jacket cooling water inlet are arranged in a linkage manner, and the valve opening degree of the automatic regulating valve of the furnace jacket cooling water inlet is automatically regulated according to changes of the temperature of the circulating cooling water outlet of the smelting furnace jacket; the smelting furnace outlet flue gas temperature, the smelting furnace outlet oxygen content and the air supplement machine are subjected to linkage setting, and the rotating speed of an air supplement machine is automatically adjusted; and an automatic exhaust valve is arranged on a cooling water outlet pipeline, so that non-condensable gas and a small amount of steam are automatically discharged, and a furnace jacket is ensured to be full of water. Meanwhile, the invention further discloses a waste recycling environment-friendly metallurgical furnace control system.

Description

technical field [0001] The invention relates to the technical field of waste resource treatment, in particular to a control method and a control system for waste resource recovery environment-friendly metallurgical furnaces. Background technique [0002] Waste recycling is the use of various engineering techniques and management measures to recover useful substances and energy from waste. In the process of recycling waste, it is a common method to smelt solid waste through metallurgical furnaces and then extract useful substances such as precious metals, or recover energy such as heat. In the prior art, side-blown smelting furnaces and closed blast furnaces are usually used for solid waste smelting; however, during the operation of these existing metallurgical furnaces, manual operations are intensive, and the on-site working environment is harsh. Wind replenishment and temperature adjustment are based on manual operations, which not only require high technical personnel sk...
