Silicon carbide heat exchanger

Silicon carbide has high strength, high temperature resistance, high thermal conductivity, and comprehensive acid, alkali, and corrosion resistance properties. It can be an excellent substitute for graphite, stainless steel, tantalum metal, Hastelloy alloy, fluoroplastics, and other traditional materials. In extreme environments of high temperature, high pressure, strong corrosion, and high wear in industries such as chemical, pharmaceutical, and metallurgical industries, silicon carbide heat exchangers are the best choice and inevitable trend,

Graphite heat exchanger

Graphite heat exchanger is a kind of ** heat exchanger equipment, mainly composed of graphite tube bundles and shells. Graphite material has excellent thermal conductivity and corrosion resistance, and can operate stably under extreme working conditions.

Diluted sulfuric acid concentration equipment

The waste sulfuric acid first enters the filtration system to remove impurities. After impurity removal, the dilute sulfuric acid enters the gas-liquid separator from the metering tank. After reaching a certain capacity, it enters the evaporator for steam heating. The gas evaporated through gas-liquid separation in the separator is condensed through the condenser and then enters the weak acid water collection tank. Due to the vacuum effect, it can prevent the material from adhering to the inner wall of the heating tube. After the waste sulfuric acid reaches the required concentration through evaporation, it is collected and enters the automatic acid preparation system. After concentration adjustment, it is prepared to the required concentration and reused for production.

Waste sulfuric acid regeneration and reuse equipment

Based on the solubility of ferrous sulfate in sulfuric acid solution and the non volatile nature of sulfuric acid, a steam indirect heating and negative pressure evaporation concentration process is adopted. The waste sulfuric acid solution is evaporated and concentrated to reach a certain concentration of sulfuric acid. The concentrated solution is cooled to precipitate ferrous sulfate in the form of crystals, and then solid-liquid separation is carried out to obtain ferrous sulfate crystals and regenerated sulfuric acid containing a small amount of ferrous sulfate.

Diluted hydrochloric acid concentration equipment (23% -31%)

This process uses negative pressure evaporation+salt desorption for concentration. The evaporation desorption process is based on the theory of salt effect, adopting the method of adding salt evaporation desorption. Inorganic salts are added to the dilute hydrochloric acid solution that needs to be evaporated to change the relative volatility of the components and disrupt the constant boiling composition of hydrochloric acid and water.

Graphite purification wastewater and quartz sand refining wastewater

The wastewater is discharged from the workshop and enters the regulating tank, where it undergoes homogenization of water quantity and quality. Reasonable capacity setting of the regulating pool can fully utilize its water quality equalization function, ensuring that the pH value of the effluent from the regulating pool is basically stable.

Silicon carbide heat exchanger

Silicon carbide heat exchanger is a device used for high-temperature heat exchange, mainly made of silicon carbide material. Silicon carbide has excellent thermal conductivity and high temperature resistance, so it is very suitable for manufacturing heat exchangers.

Glass thinning mixed acid regeneration and reuse equipment

During the process of glass thinning, high concentration fluorine-containing waste acid will be generated. Fluorinated waste acid contains HF, HSiF6, HC1, water-soluble fluorosilicates, water-soluble fluoroaluminates, water-soluble fluoroborate, and trace amounts of solid suspended solids.
