This project is an environmental protection roasting tail gas purification and desulfurization acid production system for smelting upgrading and renovation. It is stored under normal pressure at a temperature of 70-75 degrees Celsius, and the main media are sulfuric acid and mixed acid.

· Solution

Ensuring stable operation of equipment in harsh environments and reducing maintenance costs. The equipment is divided into high-level tank and mixed acid transfer tank, made of carbon steel material, 20m: (2 units), with a diameter of 3m * 3m.

· Processing technology

The equipment adopts steel lined PTFE process, with a thickness of 3mm and a tank body of 10mm. It is designed with a climbing ladder fence, which has stable performance, safety and reliability.

The quartz sand acid washing reactor of Hubei Mingshi High Purity Material Technology Co., Ltd. is used in high temperature, high pressure, and strong acid corrosion environments to improve equipment service life and safety performance.

· Technical analysis

In response to the problem of impurities in quartz sand that cannot be extracted, this rotary acid washing and purification equipment is adopted to completely solve the problem of impurities in quartz sand, improve acid washing efficiency, and reduce maintenance costs.

· Solution

The first phase of mixed acid washing in the reaction kettle includes 22 units of 2000L, and the acid washing reaction kettle is equipped with a PLC automatic acid storage tank and a double cone acid washing reaction kettle.

As a supporting supplier for this project, our company mainly provides customers with anti-corrosion mixing tanks, discrete and horizontal, with several specifications (60m; 10 units, 30m35 units, 5m4 units).

· Requirements Analysis

Medium: concentrated sulfuric acid, ammonia gas, temperature: 100 degrees, normal pressure, lined with PTFE 3mm, with water seal, stirring, and equipped with 304 ladder fence.

· Solution

In hazardous waste treatment projects, steel lined PTFE mixing tanks play an important role in treating concentrated sulfuric acid. They can resist corrosion from concentrated sulfuric acid, prevent impurities from entering hazardous waste, achieve uniform mixing with good sealing performance.

The integrated project for the recycling and utilization of lead-acid battery resources includes a steel lined PTFE tower and its internals for desulfurization, acid production, and denitrification systems. This is a 100m ³ refined acid absorption tower

· Main medium

S02、S0398%H2S04, Normal pressure, temperature 55-100 degrees, medium 3 * 14 meters, lined with PTFE 3mm, painted externally, and all tower internals are treated with PTFE anti-corrosion.

· Processing technology

Our company provides a complete set of design and production services. The equipment has been running steadily and the customer is very satisfied.

· Solution

The design dimensions of the flue gas duct shell are 3000x3000x3000, and the anti-corrosion surface is a rectangular elbow and a Tianfang Diyuan flue.

· Processing technology

Addressing key processes such as flue gas desulfurization and denitrification, we provide efficient anti-corrosion solutions to customers' internal flue gas corrosion and negative pressure issues, reducing maintenance costs.
