日東化工機 List of Products and Services

- All of our intake and exhaust ports are made of rigid polyvinyl chloride (PVC) resin, which offers excellent corrosion resistance and is ideal for acidic and alkaline air supply and exhaust. - The material has low thermal conductivity and temperature conductivity, making it less prone to condensation. - Utilizing the characteristics of PVC, it is effective for air supply and exhaust in the following locations: "Near the sea, where metal is prone to rust" "In places like hot springs and pools, where condensation is likely to occur." - Being made of PVC, the main body is lightweight, and we can accommodate various installation methods such as "flange fastening" and "welded bolt fastening." - We offer a variety of sizes.

In recent years, there has been an increase in complaints about relatively low-odor intensity unpleasant smells that are closely related to daily life in modern society. "Mini Clean" is a simple deodorizing device that can be used in a wide range of fields. It features a movable structure that does not require a specific installation location, making it easy to change the installation site. - Compact design with an integrated deodorizing fan for space-saving - The main body is made of a resin material - Excellent deodorizing performance achieved with a high-performance activated carbon filter - Continuous operation monitoring with a manometer gauge - Easy maintenance of the activated carbon filter - No electrical work required as it connects to a 100V AC outlet

- The dilution ratio can be adjusted according to the odor intensity of the odor source, allowing for deodorization with the optimal dilution solution tailored to your needs. - The only utilities required are "tap water" and "100V power supply." It is equipped with casters, making it easy to move. - Choose the most suitable model from among the combined spraying/applying machine, spraying-only machine, and applying-only machine. - Both spraying and applying methods can utilize either a handheld gun or a fixed piping nozzle interchangeably. - By adding the optional one-hour cycle timer, long-term unmanned operation management is possible. - The dilution solution is automatically mixed at the set dilution ratio (during automatic mode operation).

• Hazardous material processing

- The coating film of the steel pipe is seamless. It forms a complete film on the "inner and outer surfaces" of the steel pipe. There are no "joints" at all, resulting in a highly reliable PVC coating structure without pinholes. - Coating can be easily applied even to traditionally labor-intensive items like header pipes and perforated plates that require "manual application." - Coating of large and large-diameter items is possible. A full coating can be achieved in a single operation for items up to 1500 mm wide, 5500 mm long, and 1500 mm high. - It has excellent seawater resistance. When steel pipes, stainless steel pipes, etc., are used in seawater, "corrosion" and "marine organism adhesion" become significant issues. Applying "seamless lining" to such areas makes it difficult for marine organisms to adhere, and even if they do, removal is easier compared to other materials. - On-site repairs are possible. The material is "thermoplastic resin." If scratches occur during the installation or use of piping, repairs can be made on-site through PVC welding, and the repaired section can be used immediately afterward.

• Piping Materials

"NT Hyper" is an activated carbon (crushed form) deodorant using an oxidation catalyst to remove complex odors (acidic gases, basic gases, sulfur-based gases) generated from sewage treatment facilities. Halogen compounds and metal catalysts are attached to the activated carbon. Hydrogen sulfide (acidic gas) is oxidized to sulfur dioxide (SO₂), reducing its concentration to below 0.01 ppm. Additionally, based on the location of odor gas generation, treatment air volume, concentration, etc., the appropriate amount of activated carbon filling and lifespan are calculated. 【Features】 ■ Removes odors such as hydrogen sulfide, methyl sulfide, ammonia, and methyl mercaptan ■ Prevents pore blockage of hydrogen sulfide through the catalytic cycle of metal catalysts, improving reactivity ■ Achieves long life by restoring performance through the catalytic cycle ■ Reduces maintenance (replacement) workload *For details, please request materials or view the PDF data from the download section.

In recent years, regulations regarding odors have been increasing among environmental issues, and our activated carbon adsorption tower is the type of equipment most widely used for the removal of substances commonly referred to as unpleasant odors. - The device contains activated carbon inside, and it is a system that adsorbs odorous gases onto the activated carbon. - Utilizing the adsorption capacity of activated carbon, it has recently been used not only for the eight major odorous substances in sewage treatment but also for gases with small particles, such as incense. We always consider the maximum removal efficiency and minimum cost based on the location of odor gas generation, treatment airflow, and concentration, and we propose a type of deodorization equipment tailored to our customers' needs.

• Gas recovery/treatment equipment

The exhaust gas treatment device is a system that removes gases by introducing acidic, alkaline, and organic gases into a device where water or chemical solutions are circulated, allowing for gas removal through gas-liquid contact. The PB scrubber ensures that gas-liquid countercurrent contact occurs reliably and uniformly. Thanks to a special spraying method, it distributes evenly, preventing clogging. Compared to conventional scrubbers, it has a more compact volume, and the pressure loss within the tower remains stable at around 80 mmAq. The main body of the washing tower, circulation tank, pump, and accessories are made of rigid PVC or FRP, ensuring corrosion resistance and durability. There are options for water washing and chemical washing methods. An explosion-proof version made entirely of stainless steel is also available. It is possible to incorporate a system that adjusts the pH value of the wastewater to meet water quality standards before discharge.
