Abstract

The invention discloses a waste heat utilization method of oxidized red lead powder. The waste heat utilization method includes the following steps of quantitative feeding, cold air blowing, first-time waste heat recycling, oscillation cooling, second-time waste heat recycling, third-time waste heat recycling and flying dust recycling. The waste heat utilization method overcomes the defects in theprior art; according to the waste heat utilization method, the oxidized red lead powder with the temperature being about 500 DEG C is cooled through normal-temperature air and is subjected to two times of cooling plate cooling, and therefore the temperature at which the oxidized red lead powder flows out from a discharge port can be lower than 60 DEG C, and workers can directly package the red lead powder; and by means of the effect of a dust removal cover and an induced draft fan at the position of the discharge port, recycling of oxidized red lead powder flying dust is achieved, and harm caused by the oxidized red lead powder flying dust to the workers is eliminated.

Description

technical field [0001] The invention relates to the technical field of waste heat utilization methods, in particular to a waste heat utilization method of oxidized red lead powder. Background technique [0002] Red lead oxidation furnace is the main equipment for red lead production. The furnace temperature of red lead oxidation furnace is about 500°C when it works, and the initial temperature of oxidized red lead powder produced by red lead oxidation furnace is also about 500°C. At this time, the temperature of the oxidized red lead powder is too high to be packaged, and the heat of the oxidized red lead powder cannot be fully recycled, resulting in a waste of resources. Contents of the invention [0003] The purpose of the invention is to provide a waste heat utilization method of oxidized red lead powder to overcome the deficiencies in the prior art. [0004] In order to solve the above problems, the technical scheme adopted in the present invention is as follows: [...
