A self-preheating mercury-containing material distillation device

Abstract

The invention relates to the technical field of mercury-containing material distillation equipment, and particularly relates to a self-preheating mercury-containing material distillation device. The mercury-containing material distillation device comprises a preheating layer A, a material storage layer B, a distillation layer C, a ventilation tower, a waste material gathering room, a combustion tray, a waste material conveying pipe, a tower bottom combustor, a flow divider, a fuel gas transporting pipe a, a fuel gas transporting pipe b and a fuel gas header pipe, wherein the material storage layer B is arranged below the preheating layer A; the distillation layer C is arranged below the material storage layer B; the ventilation tower is arranged at the bottom of the distillation layer C; the waste material gathering room and the combustion tray are arranged on the ventilation tower; the waste material conveying pipe is arranged at the bottom of the waste material gathering room; the tower bottom combustor is arranged at the bottom of the combustion tray; the bottom of the tower bottom combustor is connected to the flow divider; the fuel gas transporting pipe a and the fuel gas transporting pipe b are also arranged on the flow divider; and the fuel gas header pipe is arranged at the bottom of the flow divider. When the distillation device is used for distillation treatment of the mercury-containing material, the distilled mercury vapor exchanges heat with the mercury-containing material, so that the purposes of preheating and precooling are achieved, the energy consumption is reduced, and cooling water is saved. The mercury-containing material is uniformly heated and distilled in a distillation pipe through arrangement of a fire-jet head and the combustion tray, thereby improving the recovery rate of mercury.

[0002] The equipment used for the treatment of mercury-containing materials has become one of the more serious problems faced by mercury processing or production enterprises. Due to the unreasonable structure setting, it often leads to the leakage of mercury components during the treatment of mercury-containing materials, which in turn causes Large-scale environmental pollution even threatens people's health and safety. For this reason, with the introduction of relevant policies by the environmental protection department, mercury production and processing enterprises are faced with the adjustment and control of mercury emissions.

[0003] In the prior art, due to the unreasonable combination of the device for mercury distillation treatment, high energy consumption is required in the distillation process to heat the mercury-containing material put into the distillation furnace, and the uniformity of heating is also low. It still cannot meet the demand of mercury-containing materials, and then makes some mercury-containing materials less complete in double distillation, which makes the amount of mercury-containing components in the discharged waste larger, which leads to environmental pollution, and in the entire treatment process Among them, due to the unreasonable selection of structure and material, its corrosion resistance is poor and its heating speed is slow, which in turn makes the processing of mercury-containing materials consume a lot of energy, the cycle is long, and the cost is increased; moreover, after treatment The formed mercury vapor needs to be cooled, and its energy consumption is difficult to be recycled, and it needs to consume a large amount of cooling water, resulting in a high output rate of wastewater and high energy consumption
