Description

technical field [0001] The invention relates to a brand-new horizontal automatic electric heating distillation furnace, which belongs to the field of nonferrous metal smelting. Background technique [0002] At present, domestic mercury-containing waste recycling companies generally use vertical tube distillation furnaces or rotary kilns to recover metallic mercury. Most of the heating methods are coal-fired, and some companies use coal-produced steam as a heating source. Standpipe distillation furnaces or rotary kilns cannot be produced continuously. Each batch of mercury-containing waste recovered needs to go through the processes of filling, heating, heat preservation, cooling, and unloading. The operation time is long, the degree of automation is low, and a large amount of labor is required to complete. . Since vertical tube distillation furnaces or rotary kilns are often clogged, continuous production is not possible, resulting in low disposal efficiency and high energy...

AI Technical Summary

Problems solved by technology

Standpipe distillation furnaces or rotary kilns cannot be produced continuously. Each batch of mercury-containing waste recovered needs to go through the processes of filling, heating, heat preservation, cooling, and unloading. The operation time is long, the degree of automation is low, and a large amount of labor is required to complete.

Since vertical tube distillation furnaces or rotary kilns often have furnace blockages, continuous production is not possible, resulting in low disposal efficiency and high energy consumption

Usually, due to the large volume of vertical tube distillation furnace or rotary kiln, it is difficult to control the temperature accurately, and the materials in various areas in the furnace will be heated unevenly, resulting in a low recovery rate of metallic mercury in some materials.

Due to the repeated opening and closing of the vertical tube distillation furnace, the airtightness of the furnace is affected, and a large amount of mercury vapor and dust escape, causing environmental pollution and physical hazards for operators.

Since the vertical tube distillation furnace or rotary kiln is heated by coal, it is easy to cause secondary pollution to the environment
