Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0019] see figure 1 As shown, the present invention is a method for twisting the twisted grass rope of a fully automatic straw pad forming machine. The waste mercury regeneration technology includes the following steps: collecting the original waste mercury, and injecting the original waste mercury through the corrugated suction pipe 402 In the particle filter 4, the particle filter 4 filters the particle impurities on the surface of the original waste mercury, and the particle impurities are discharged into the particle collection box 3 through the particle discharge pipe 401; the remaining waste in the particle filter 4 Mercury will be discharged into the interior of the precipitation tank body 1. At this time, 2% and above nitric acid is poured into the interior of the prec...

Abstract

The invention discloses a synergistic waste mercury regeneration technique and a soaking precipitation pool thereof, and relates to the technical field of ore excavation. The technique comprises the following steps that original waste mercury is collected, and injected into a particulate filter through a corrugated suction pipe, at the moment, particulate impurities on the surface of the original waste mercury are filtered through the particulate filter, and the particulate impurities are discharged into a particulate collection box through a particulate discharge pipe; residual waste mercury in the particulate filter can be discharged into a precipitation pool body, and at the moment, 2% or more of nitric acid is poured into the precipitation pool body through an immersion pipe, so that the waste mercury is soaked in the nitric acid, and meanwhile, the waste mercury reacts with the nitric acid to generate mercuric nitrate; and after mercury nitrate is generated, the mercury nitrate and metal elements in the original waste mercury are subjected to a replacement reaction, mercury in the mercury nitrate is replaced at the moment, and the waste mercury is regenerated at the moment. According to the technique, through the chemical reaction between nitric acid and waste mercury, recycling of waste mercury is achieved, and cost waste is reduced.

Description

technical field [0001] The invention belongs to the technical field of ore mining, and in particular relates to a synergistic waste mercury regeneration technology and a immersion and precipitation pool thereof. Background technique [0002] Now when the ore in the mine is processed, the methods of mining, dressing and smelting are adopted. In order to achieve the goal of qualified zinc ingot products, it is necessary to carry out corresponding laboratory analysis on the entire system to provide data basis for each individual system. Currently, in the analysis process In the determination of cadmium, a large amount of mercury is needed, but it still has the following disadvantages in actual use: [0003] Because the utilization rate of mercury is very low, it is always used once and then not used again; mercury itself is volatile and toxic, and the storage requirements are relatively high; it is an item that is not easy to store, and it is also a waste in terms of cost.
