Embodiment 1

[0045] This embodiment provides a method for controlling heavy metal treatment, which is used to control a heavy metal treatment device. The heavy metal treatment device includes a reaction furnace for pretreating raw materials. The reaction furnace includes a feed port for adding raw materials to the reaction furnace. The control feed port Switching equipment for opening and closing, and temperature detection equipment for detecting the temperature of the reaction furnace, wherein the heavy metal treatment control method includes:

[0046] S101. Obtain the preset feeding interval time and feeding duration, and control the opening and closing of the switchgear, the feeding interval time and the feeding duration according to the preset feeding interval time and feeding duration Determined according to the heavy metal and miscellaneous ingredients of the raw material;

[0047] Specifically, set the feeding interval, the duration of each feeding and the temperature threshold acco...

Embodiment 2

[0055] The heavy metal treatment control method provided in this embodiment is applied to the pretreatment link of heavy metal extraction and recovery. When there are too many non-heavy metal components in the raw material, it is necessary to process the raw material, remove some miscellaneous materials, and then carry out the extraction and recovery of heavy metals, or, when the raw material contains specific components that need to be removed in advance, such as those that pollute the environment. For arsenic, it is necessary to remove the arsenic in the raw material first, and then carry out the extraction and recovery of heavy metals. The step of removing miscellaneous materials or specific components before this heavy metal extraction and recovery step is called the pretreatment process of heavy metal extraction and recovery.

[0056] The raw materials in this embodiment refer to materials containing heavy metals and other specific substances that need to be removed in the...

Embodiment 3

[0078] The heavy metal treatment control method provided in this embodiment is applied to the extraction of heavy metals in pretreated raw materials. The raw materials in this embodiment are pretreated materials. For example, for materials containing heavy metal antimony, raw The material refers to the material containing the heavy metal antimony after removing the specific substance arsenic. The process of extracting the target heavy metal antimony from the material containing the target heavy metal antimony after removing the specific substance arsenic is the extraction process of heavy metals.

[0079] The heavy metal treatment control method provided in this embodiment is mainly used to control the heavy metal extraction device for raw materials containing heavy metals. The heavy metal extraction device includes an extraction reaction furnace for extracting heavy metals from the raw material. The feed port for adding raw materials, the first discharge port for discharging h...

Abstract

The invention provides a heavy metal treatment control method. The method is characterized in that the feeding time interval and / or the duration of each feeding is adjusted to slow down the feeding of the raw material when the temperature in a reacting furnace is less than a temperature threshold or materials reacted through the reacting furnace contains removed substances; the feeding time interval and / or the duration of each feeding is adjusted to speed up the feeding of the raw material when the temperature in the reacting furnace is higher than the temperature threshold. With the adoption of the heavy metal treatment control method, the heavy metal treatment efficiency can be raised.

Description

technical field [0001] The present application relates to the field of smelting technology, in particular to a heavy metal treatment control method and system. Background technique [0002] Heavy metals refer to metals with a density greater than five. Heavy metals generally have obvious toxicity, which will pollute the environment and cause great harm to people's health. [0003] In metal smelting, the miscellaneous materials after metal smelting contain heavy metals. In order to prevent heavy metals from polluting the environment, the heavy metals in the original materials need to be extracted and recovered before the miscellaneous materials are utilized or discharged. [0004] At present, the processing method in the extraction and recovery process of heavy metals in the prior art is to manually judge the feed amount and to manually add raw materials for the heavy metal processing process, which makes the entire heavy metal processing process inefficient. Contents of th...
