According to the design, the waste heat circulation box body 12, the circulation fan 13 and the waste heat circulation pipeline 14 are arranged on the steam discharge pipeline 11, so that a large amount of heat generated by heating and removing mercury can be recycled, and the energy loss of mercury removal and recycling is reduced.
Further, as shown in fig. 4, the middle section of the waste heat circulation pipe 14 is located inside the heating decomposition tank 10, and the middle section of the waste heat circulation pipe 14 is spiral, so that the heat dissipation area can be effectively increased, and the utilization rate of waste heat recovery can be improved.
Further, the circulating fan 13 is a high-temperature circulating fan, the temperature born by the circulating fan 13 is higher than the highest temperature in the heating decomposition tank 10, so that the waste heat can complete closed loop circulation in the waste heat circulating pipeline 14, and the contact with the external environment is reduced.
Specifically, the high-temperature circulating fan is mature in the prior art, so specific performances of the high-temperature circulating fan are not repeated here.
More specifically, the heating decomposition tank 10 is internally provided with a heating component, a stirring component and a temperature control component, which are relatively mature in the prior art, and meanwhile, the pre-treatment equipment such as the crushing tank and the subsequent treatment equipment such as the condenser, the collecting tank, the tail gas treatment device and the like are relatively mature in the prior art, and the specific design can refer to the existing products, so that the details thereof are not repeated herein.
