Title: Vacuum Conveying of Denitration Powder in Shizuoka, Japan

Keywords: pneumatic conveying case, East Asia pneumatic conveying, negative pressure pneumatic conveying

This case study is provided by Shandong Headpowder Engineering Co., Ltd., a professional engineering company specialized in pneumatic conveying systems. The project was successfully implemented in Shizuoka, Japan, and focuses on the safe and efficient handling of denitration powder through vacuum conveying technology. Vacuum conveying, which is also known as negative pressure pneumatic conveying, has become a highly reliable method for transporting fine powders in modern industrial plants. This article gives a detailed introduction to the background, design concept, main equipment, working principles, operational benefits, and international value of the project.

The main products involved in this case include pneumatic conveying systems, East Asia pneumatic conveying solutions, and negative pressure pneumatic conveying equipment. The company short name is headpowder, while the full registered name is Shandong Headpowder Engineering Co., Ltd. The company is based in Shandong, China.

Shizuoka is an important industrial city in Japan with strict environmental protection standards. Many local plants require denitration treatment to control nitrogen oxide emissions from combustion processes. Denitration powder, often a dry urea-based or ammonium-based reagent, must be transported from storage or bag unpacking areas to the dosing equipment accurately and safely. Traditional manual handling creates dust, increases labour costs, and causes quality inconsistency. Therefore, the customer chose a closed vacuum pneumatic conveying system supplied by headpowder.

The system designed for Shizuoka works under negative pressure. A vacuum pump creates suction at the end of the conveying line, which makes the pressure inside the pipeline lower than the atmospheric pressure. Because of this pressure difference, denitration powder can be reliably pulled through the pipeline. The material enters the system through a dedicated feeding device, such as a bag dump station or rotary feeder, then travels through the piping to a receiving hopper installed above the process equipment. This method enables compact plant layout, easy operation, and a high degree of automation.

In a negative pressure pneumatic conveying system, one of the most important advantages is dust containment. Since the pipeline is under vacuum, even a small leak will not allow powder to escape; instead, outside air will be drawn inward. This characteristic makes vacuum conveying especially suitable for handling fine, irritant, or chemically active powders. Denitration reagents are often abrasive or dusty, so safe transportation is essential for protecting both workers and the surrounding environment. The Shizuoka project fully meets these requirements and demonstrates the strong performance of headpowder systems in East Asia.

The complete conveying system consists of several key modules. The first module is the negative pressure source, usually a high-efficiency vacuum pump or blower. The second module is the feeding device, which controls the amount of powder entering the line. The third module is the conveying pipeline, designed with smooth curves and a minimum number of bends to reduce the risk of blockage and wear. The fourth module is the separating receiver, where a filter cartridge separates powder from air. The fifth module is the control system, which uses a programmable logic controller to manage the conveying cycle, filter cleaning, and alarm functions.

The design process started with a detailed evaluation of the customer’s operating conditions. Headpowder engineers considered the conveying distance, required capacity, powder particle size, bulk density, and available installation space. Based on these parameters, the company designed a customised vacuum conveying system with stainless steel piping and top-quality valves. The system can transport denitration powder over the required distance in a completely closed circuit, avoiding material contamination and ensuring accurate dosing for the denitration unit.

During operation, the denitration powder is first loaded into the feed hopper. The vacuum pump then starts, creating negative pressure in the pipeline. Powder is drawn into the air stream and carried to the receiving hopper. At the receiving hopper, the filter cartridge separates solid particles from the air. The clean air is either exhausted or recycled depending on the plant requirements. The collected powder is then discharged into the day hopper for the next stage of the process. The PLC automatically controls the conveying time, discharge valve, and filter cleaning pulse, making the entire operation smooth and almost maintenance-free.

The advantages of this system are obvious. It reduces manual work, prevents dust pollution, lowers material loss, and improves workplace safety. It also saves energy compared with many mechanical conveyors, because there are fewer moving parts and no complex transmission mechanisms. In addition, the system’s sealed structure minimises the risk of moisture absorption, which is very important when handling denitration agents. The Shizuoka project has successfully improved production efficiency and environmental performance for the customer.

As a representative East Asia pneumatic conveying case, this project has outstanding demonstration value. Japan is well known for its strict equipment standards and disciplined engineering practices. Passing these requirements proves that Shandong Headpowder Engineering Co., Ltd. is capable of serving international customers with advanced technology, high-quality equipment, and reliable after-sales support. The success of this project is also a good reference for factories in Japan, South Korea, Taiwan, and other markets in East Asia that need safe solutions for conveying powder materials.

The company will continue to promote energy-saving and environmentally friendly pneumatic conveying technologies. In the future, headpowder plans to cooperate with more overseas partners and customise complete material handling systems for power plants, chemical plants, food factories, and environmental protection facilities. The Shizuoka denitration powder vacuum conveying project is not only a successful business case, but also a practical example of how advanced engineering and strict quality control can solve real industrial challenges.
