In the chemical, environmental protection, and energy industries, the coordinated treatment of ammonia water and solid powders often faces many challenges. Traditional manual feeding or mechanical conveying methods are not only inefficient but also prone to ammonia leakage, dust pollution, and equipment corrosion, seriously affecting production safety and environmental compliance. Head Powder addresses this industry pain point by providing solutionsAmmonia water is paired with solid powder pneumatic conveying systemsCustomized solutions to help enterprises achieve sealed, efficient, and clean material flow.

Customer pain points

Many enterprises commonly encounter the following problems during the mixing or dosing of ammonia water with solid powders (such as limestone powder, desulfurizers, coal powder, etc.): ammonia water is highly volatile and has a strong on-site odor, threatening operator health; Solid powders are prone to dust during transport, polluting the workshop environment; Traditional equipment struggles to cope with the corrosiveness of ammonia water, resulting in high maintenance costs; Manual measurement is not accurate, causing fluctuations in ingredient ratios and affecting product quality; The system has a low degree of automation and cannot efficiently connect with upstream and downstream processes.

Material characteristics

The solid powders involved in this solution typically have the following characteristics: wide particle size distribution (from micron to millimeter level), low moisture content, and easy absorption and caking; Some powders are strongly alkaline or weakly acidic, and may release heat or undergo chemical reactions upon contact with ammonia water; There is a significant difference in powder flowability, and some powders tend to adhere to walls or form bridges. At the same time, ammonia is a weakly alkaline liquid, and its corrosiveness requires the system materials to have good corrosion resistance, and the pipeline sealing must meet high standards to prevent leakage.

Product Introduction

Head Powder's ammonia water solid powder pneumatic conveying system is an integrated solution that integrates the gas source system, feeding device, conveying pipeline, dust separation and removal, and automatic control. The system uses positive or negative pressure pneumatic conveying methods, accurately delivering solid powder through sealed pipelines to ammonia-water mixing tanks or reactors. It can also be equipped with ammonia water quantitative dosing modules to achieve continuous and stable powder-to-liquid ratios. The equipment materials are selected from 304 stainless steel, 316L stainless steel, or special anti-corrosion coatings, effectively resisting chemical corrosion from ammonia water. The entire system can be customized non-standard according to on-site working conditions to meet different physical properties, production capacities, and layout requirements.

Product advantages

To address customer pain points, this solution offers the following improvement measures:

• Fully sealed conveying, zero leakage: System pipelines and connectors all adopt a high-seal design, allowing materials to flow in a sealed environment, with no ammonia leakage and low dust emissions, meeting environmental protection and occupational health requirements.
• Corrosion-resistant design with long service life: Components in contact with ammonia water are treated for corrosion resistance or selected with corrosion-resistant alloys, reducing equipment corrosion rates, replacement frequency, and overall operation and maintenance costs.
• Intelligent control for relatively accurate measurement: Integrates PLC and weighing sensors to monitor powder flow and ammonia water addition in real time, automatically adjusting conveying speed to help batching accuracy remain within the industry's standard range.
• Modular combinations, flexible expansion: Feeders, valves, and pipelines can be freely combined according to capacity changes; future expansion only needs to add module units without dismantling the existing system.

Supported by years of experience in pneumatic conveying engineering, Head Powder provides customers with end-to-end services from solution design and equipment manufacturing to installation and commissioning. Whether for new projects or retrofitting old lines, customized solutions can be provided based on actual material measurement data, helping enterprises improve production efficiency, reduce operating costs, and achieve green and safe production.
