Product Description: Price of 12kg Marine Zinc AnodeThe use of zinc as a corrosion-resistant metal has a long history. It is well-known that this method is applied to protect ship hulls, boilers, and the outer walls of internal combustion engine cylinder liners from corrosion. However, further research into materials and installation methods has only been conducted in the past 20 years. During this period, technologically advanced countries like the United States began improving materials and dimensions, while China has also achieved continuous progress in the research of galvanic anodes made of zinc. The performance of corrosion-resistant zinc, with trace additions of cadmium and aluminum, has been increasingly effective. These studies are all based on high-purity zinc. The principle is sound: zinc corrodes before iron, and ships in the ocean are often equipped with zinc anodes. While this is feasible during use, especially for personal assets like cars, it becomes more complicated for manufacturers to implement such measures during production.During the production of fuel tanks, rust issues also arise, particularly during storage in warehouses. In an enclosed internal environment, even the slightest moisture or vapor can quickly lead to corrosion. A more appropriate approach is to use vapor-phase corrosion inhibitors (VCI oils), which require minimal amounts and do not affect the later use of the fuel tank, as they are mutually soluble with gasoline. Yes, zinc is more reactive than iron! During anodic reactions, zinc's reducing properties are stronger than those of iron, causing zinc to react with oxygen first. This rust prevention method is called sacrificial anode protection.The specific method involves connecting a more reactive metal as the protective electrode to the metal to be protected, forming a galvanic cell. The more reactive metal acts as the anode, undergoing oxidation and being consumed, while the protected metal serves as the cathode, thus avoiding corrosion. Because this method sacrifices the anode (the negative electrode of the galvanic cell) to protect the cathode (the positive electrode of the galvanic cell), it is called sacrificial anode protection.Corrosion-resistant zinc anodes belong to the category of sacrificial anodes, with the protected objects acting as cathodes (such as ship hulls, pipelines, storage tanks, and marine engineering facilities). Essentially, this utilizes the principle of a galvanic cell. We have been sourcing from Libo Corrosion Protection Company for years. The quality is excellent.Zinc-aluminum-cadmium series (ZAC series) sacrificial anode products (abbreviated as zinc anodes) are certified by the China Classification Society (CCS). Their quality standards comply with the GB/T4950-2002 standard, and their chemical composition meets the US MIL-A-18001H and ASTM-B418 (Type 1) standards.This product has the following characteristics:1. Zinc alloy sacrificial anodes have low self-corrosion.2. High current efficiency, with good self-regulating performance of the anode current.3. Chemical composition of zinc anodes more>

Company: Guangzhou Najie Environmental Protection Technology Co., Ltd.

Product Description: The SCR reactor and auxiliary systems consist of an ammonia injection system, SCR reactor, catalyst, soot blowing system, flue, etc.The SCR reactor contains catalyst layers where, under the action of the catalyst, NH₃ reacts with NOx to remove NOx. The catalyst promotes the reaction between ammonia and NOx. At the top of the SCR reactor, there is a rectifying grid to ensure uniform distribution of the flue gas flow. The catalyst is installed in modular units for easy handling, installation, and replacement. Soot blowers are installed between the catalyst layers of the SCR reactor to remove dust and SCR reaction by-products deposited on the catalyst, thereby reducing the reactor pressure drop.1) SCR ReactorThe reactor is equipped with optimized distribution devices and an ammonia injection grid. Catalyst beds are installed in the vertical section of the reactor, divided into two layers. The reactor adopts a fixed-bed parallel channel configuration.2) Ammonia Injection SystemTo ensure uniform distribution of ammonia in the flue gas and facilitate adjustment of the NH₃/NOx molar ratio in the flue gas above the first catalyst layer in the reactor, ammonia injection ports are installed at appropriate locations in the inlet flue.3) Heating SystemElectric heating is used to raise the temperature of the raw flue gas (applied when necessary).4) Soot BlowerThe use of soot blowers ensures continuous cleaning of the catalyst, thorough dust removal without dead zones, maximizes the catalytic activity of the catalyst for denitrification reactions, extends the catalyst's service life, and reduces SCR maintenance costs. Each channel and each layer of the SCR denitrification system is equipped with a compressed air soot blowing system.5) CatalystCurrently, there are three mainstream types of SCR catalysts on the market: honeycomb, plate, and corrugated plate. Global SCR operational practices show that excellent system design and appropriate catalyst selection, based on actual design conditions, can ensure SCR system performance. Guangzhou Najie Company, based on catalyst usage and operational experience, as well as analysis of the design conditions of this project—including operating conditions, fuel, and fly ash properties—has comprehensively considered economic and safety factors and selected medium-low temperature honeycomb catalysts for this project. The reasons are as follows:a) In terms of volume, as shown in the structural diagram above, the honeycomb type has a large contact area and requires nearly 30% less total volume compared to other catalysts under the same design conditions. Therefore, choosing honeycomb catalysts can reduce reactor size and lower the initial investment cost of the SCR system.b) The flue gas temperature does not reach the active temperature range of high-temperature catalysts, so specialized medium-low temperature SCR honeycomb catalysts are used.c) Specialized medium-low temperature SCR catalysts have a wide adaptation temperature range, typically 200-350°C.d) The catalyst used is a specially developed medium-low temperature honeycomb catalyst with low SO₂ oxidation rate, designed for high-dust, high-sulfur, and high-NOx conditions. This catalyst has been applied in many building material kiln projects, demonstrating excellent anti-poisoning performance and efficiency.f) Based on analysis of actual operating conditions, the ash content and properties, as well as flue gas parameters of this project, fall entirely within the experience database range of medium-low temperature honeycomb catalysts with low SO₂ oxidation rates. The catalyst manufacturer guarantees that the selected honeycomb catalyst is fully capable.When the temperature is between 20°C and 150°C, the catalyst should be able to withstand a minimum temperature rise rate of 10°C/min.When the temperature is between 150°C and 300°C, the catalyst should be able to withstand a minimum temperature rise rate of 50°C/min.Ms. Fu 17324005195https://www.najiehuanbao.com more>
