Encapsulated Pre-Treatment Protection Hot Dip Galvanizing Line Plant Equipment Zinc Kettle Best Provider Supplier
Enclosed Pretreatment Workshop Design Guidance
Enclosed pickling is the most advanced and environment-friendly pickling method. The acid mist reaches environmental emission standards by using a vacuum blower sucks it into the pipeline and then deals with it in the water tower.
Working Principle
The scrubber uses sodium hydroxide solution as a Neutralization Solution to purify the acid fume. The air is sucked into the air inlet section by the centrifugal fan, flows first from up to down, then from down to up, passes through the first filter layer and reacts with the neutralization solution from the first stage nozzles. The air continues to flow upward to the second and third filter layers, reacts with the neutralization solution sprayed from the second and third stage nozzles, reacts with neutralization again, and then is discharged into the atmosphere through the exhaust pipe.

| Acid fume scrubber | Hydrochloric acid fume |
| Inlet air concentration mg/m3 | 152 |
| Outlet air concentration mg/m3 | 8 |
| Removal rate % | 95 |
| Emission concentration mg/m3 | 8 |
| Emission standard mg/m3 | 45 |
| Emission rate kg/h | 1.5 |
Our service:

Demand communication--- Custom plant--- Supply of hot dip galvanizing equipment--- Assembly and commissioning--- Supply of galvanizing techniques--- After-sales service
- Design zinc kettle: choosing the best dimension for the galvanizing kettle according to the plant size, material size and dealing capacity.
- Plant layout: arranging the plant according to the land size, environmental requirement, and galvanizing process
- Civil work design: supplying calculations and building drawings in steel and concrete.
- HDG equipment: manufacturing of galvanizing factory equipment from A to Z, including all the necessary equipment and auxiliary equipment.
- Installation and commissioning: offering installation service and users’ guidance, supply of galvanizing chemicals and adjustment technology.
Design Method
Step 1: Choose plant type - 3D plant layout
Compared with the traditional Auto CAD drawings the 3D view design presents a more clear and understandable workshop layout for the customer. Not colorful lines only designers or professionals can understand.
Step 2: Site/Online visit- VR Pre-viewing
Step 3 Confirm project -Sign the contract
After determining the requirements, we offer the corresponding quotation. The quotation includes the process introduction, equipment specifications, the responsibilities of the buyer and the seller, the equipment list, and preliminary drawings. After an on-site or online discussion, both parties will determine the final contract details. At the same time, we begin to prepare circuit diagrams and installation diagrams for all the equipment. The corresponding files of the equipment, such as:
1. Machine(line) overview and specifications
2. Installation-description of each part-detailed description of the operation program
3. Operation procedure-emergency plan
4. Daily maintenance alarms and troubleshooting
5. User parameter setting and meaning.
6. Detailed control diagram
7. Mechanical and hydraulic detailed diagram
8. Electrical wiring
9. Setting parameters for each programmable part
10. Alarms and troubleshooting-preventive maintenance schedules
11. Emergency plan
After finishing the above, the conceptual design will be finished.
Manufacturing
After signing the Contract with customers, start the manufacturing works.
Purchase the steel, raw materials, electronic key parts, and other auxiliary equipment.
Design the software ( machine control-PLC and HMI) for system automation running.
Installation
The installation of mechanical parts and machines, the placement of some power supplies, controllers and other system components, and the assembly of the system. The engineers assemble and install the equipment according to the design. They weld all the steel structures together. Connect the power system and other support systems to overall arrange the entire layout management, starting the system to ensure that the equipment can run normally. Adjust the operation of the system according to the mechanical and contract terms.
Commissioning
After the equipment is installed, the trial operation shall be carried out, and the furnace combustion system shall be adjusted according to the design requirements to ensure the efficient use of heat. Adjust the traveling crane operation system to ensure smooth process flow. The most important thing is to provide customers with technical guidance on hot dip galvanizing to ensure that the galvanized workpiece can meet the technical requirements.
