Description

Technical Field

[0001] The invention belongs to the field of waste liquid treatment, and in particular relates to a waste liquid purification treatment device for cobalt chloride production and processing. Background Art

[0002] Cobalt chloride (chemical formula: CoCl2) is an inorganic compound that generally exists in two main forms: anhydrous cobalt chloride and cobalt chloride hexahydrate (CoCl2·6H2O), which differ in appearance and properties. Here are some details about cobalt chloride:

[0003] 1. Physical properties

[0004] Anhydrous cobalt chloride: Anhydrous cobalt chloride is a red crystal that easily absorbs moisture in humid air to form cobalt chloride hexahydrate.

[0005] Cobalt chloride hexahydrate: Cobalt chloride hexahydrate is a blue crystal with six water molecules. It can lose water when heated and become red anhydrous cobalt chloride.

[0006] 2. Chemical properties

[0007] Solubility: Cobalt chloride dissolves in water to form a purple solution. The color of the solution depends on the concentration of the solution and the hydration state of cobalt chloride.

[0008] Reactivity: Cobalt chloride reacts with many chemicals, including water, ammonia, and other halides. It is a common reducing agent and can act as a catalyst in different chemical reactions.

[0009] 3. Application

[0010] Desiccant: Due to its hygroscopic properties, anhydrous cobalt chloride is often used as a desiccant to absorb moisture and control humidity.

[0011] Indicators: Cobalt chloride hexahydrate can be used as an indicator of hydration status as its color change (blue to red) can indicate changes in humidity.

[0012] Catalyst: Cobalt chloride is used as a catalyst in some chemical reactions, especially in organic synthesis and petrochemicals.

[0013] 4. Security

[0014] Cobalt chloride is somewhat toxic and should be handled with caution:

[0015] Health Effects: Long-term exposure or ingestion of cobalt chloride may cause adverse health effects, including causing irritation of the respiratory tract, skin and eyes, and even allergic reactions.

[0016] Handling: When handling cobalt chloride, wear appropriate personal protective equipment such as gloves and goggles and work in a well-ventilated environment.

[0017] The waste liquid generated in the production and processing of cobalt chloride needs to be properly treated to prevent environmental pollution. The design of the waste liquid purification treatment device usually includes the following steps:

[0018] Primary sedimentation: Solid particles and sediments are removed from the wastewater through sedimentation tanks, which helps reduce the load of subsequent treatment.

[0019] Neutralization reaction: Neutralize the acidic or alkaline components in the waste liquid and adjust the pH value to a suitable range. Acid or alkaline solutions are usually used for neutralization reaction.

[0020] Sedimentation and filtration: Use a precipitant (such as lime milk) to make metal ions such as cobalt chloride become insoluble. After precipitation, the precipitate is removed by a filtration device to obtain a clear liquid.

[0021] Ion exchange: Ion exchange resin is used to remove metal ions, especially cobalt chloride, from wastewater. The treated wastewater can meet environmental discharge standards.

[0022] Evaporation and concentration: The treated liquid is evaporated to concentrate the cobalt chloride and other recyclable materials for recycling or further processing.

[0023] Waste residue treatment: Waste residue generated during the treatment process requires further treatment or disposal, such as safe landfill or incineration.

[0024] Existing publication number CN113087101A discloses a waste liquid purification treatment device for cobalt chloride production and processing, including a mixing bin, a feed pipe is fixedly provided on the upper end of one side of the mixing bin surface, a bent pipe is fixedly provided on the end of the feed pipe away from the mixing bin, a transmission mechanism is provided inside the feed pipe, the transmission mechanism includes a transmission rod, an impeller, and a first pulley, a transmission rod is movably provided on the inner side of the feed pipe through a bearing, the transmission rod, an impeller is fixedly provided at the lower end of the transmission rod, a first pulley is fixedly provided at the upper end of the impeller, a stirring mechanism is provided inside the mixing bin, the stirring mechanism includes a rotating rod, a stirring head, a second pulley, and a transmission belt, a rotating rod is movably provided on the middle part of the inner side of the mixing bin through a bearing, and a stirring head is fixedly provided at the lower end of the rotating rod.

[0026] 1.

In the preliminary sedimentation, it is necessary to ensure the effective separation of the waste liquid and insoluble substances.

[0027] 2. After the initial precipitation, the waste liquid needs to undergo a neutralization reaction so that the pH value of the waste liquid is within a suitable range. This can prevent incomplete purification due to an overly acidic or overly alkaline waste liquid environment in subsequent treatment.

[0028] 3. After the neutralization reaction, metal ions such as cobalt chloride in the waste liquid need to be converted into insoluble substances and then precipitated again to obtain relatively pure purified water. Summary of the invention
