PROJECT OVERVIEW
The three enterprises under Tangshan Iron and Steel Group are all large backbone steel enterprises with early factory construction in China. Tanggang was founded in 1943 and is known as the "hometown of converters". It is also one of the earliest enterprises in China to successfully apply continuous casting technology to large-scale industrial production. After the reform and opening up, Tangsteel has continuously accelerated its development pace and entered the top ten steel companies in the country. Xuangang was founded in 1919. During the planned economy period, it was a designated national pig iron supply base and also trained a large number of professional technical talents in mining and pig iron smelting for the metallurgical industry. Under the conditions of a market economy, Xuansteel has risen and achieved rapid development in adversity, becoming one of the key national steel enterprises. Chenggang is one of the 156 key projects established by the country in 1954. It has been committed to the development and utilization of vanadium titanium magnetite resources and the industrialization process of related scientific research achievements. It is the birthplace of blast furnace smelting technology for vanadium titanium magnetite in China and the largest vanadium containing steel production base in the north.

Design process
YQWT spray washing+YQGC coupled loaded photocatalytic oxidation+YQHX activated carbon adsorption process
Pre washing system
After being collected, the exhaust gas enters the pre-treatment stage through pipelines, and the alkaline/acidic gases in the exhaust gas are neutralized and washed using acid/alkaline solution.
Catalytic adsorption system
The pre treated exhaust gas first enters the catalytic system for treatment, then enters the adsorption system and passes through the filler. When passing through the carbon layer, organic pollutant molecules enter the micropores and are adsorbed by the active sites on the surface of the carbon layer through physical and chemical adsorption.
Exhaust emission system
Choose as needed, consisting of explosion-proof fans and high-altitude discharge pipelines to achieve exhaust gas emission standards and emission heights.
COMPLIANCE REQUIREMENT

Eclear Environmental RELATED EQUIPMENT
Washing tower
Washing tower is a mature waste gas treatment equipment widely used in pre-treatment of industrial waste gas treatment, dust removal, and other aspects. Gas enters the tower and fully contacts, adsorbs, and dissolves with the washing liquid inside the tower, achieving purification effect. The design forms of Yi cleaning towers are diverse, and vertical or horizontal structures can be used according to the project application site. The commonly used materials for washing tower equipment include PP, FRP, and stainless steel. PP and FRP are commonly used in chemical absorption towers and have the characteristics of acid resistance, alkali resistance, and corrosion resistance. Stainless steel materials can be used for high-temperature exhaust gas.
Spray tower
Spray tower, as a type of environmental waste gas treatment equipment, exists. According to its working principle, it can be divided into circulating water spray tower, alkali spray tower, and acid spray tower (also known as acid washing tower). According to the material of the tower, it is divided into fiberglass spray towers, PP spray towers, and stainless steel spray towers. Choose a reasonable spray material and spray process based on the different properties of the exhaust gas. Spray tower is an important industrial waste gas treatment equipment, whose working principle is to use water and power technology to spray liquid or gas in a mist form into the waste gas, in order to remove harmful substances in the waste gas.
Coupling catalytic all-in-one machine
The equipment adopts a stainless steel fixed pry mounted fully sealed structure, which is easy to install. The interior is coated with stainless steel special anti-corrosion material, which is resistant to acid, alkali and waste gas environments. The equipment has a long service life and is composed of a pre-treatment section, a coupled reaction device, and an array drawer type module. The high-energy particle field generated by the coupling catalytic network of precious metals is irradiated through the ultraviolet band to the coupling synergy effect of independently prepared precious metals and titanium dioxide nanoparticles. VOCs organic waste gas is decomposed into carbon dioxide, water, etc. Other waste gas molecules that have not been completely degraded can be oxidized into water-soluble small molecules and some active free radicals.

Activated carbon adsorption box
Activated carbon adsorption box is an environmentally friendly mechanical product that filters waste gas and adsorbs odors. This equipment is used to clean organic chemical waste gas and spray waste gas with high concentration. Activated carbon has a high-strength adsorption level. When the waste gas is powered by a centrifugal fan, negative pressure enters the adsorption box and then enters the activated carbon adsorption layer, it has a very good adsorption effect on organic solution waste gas.
VOCs integrated processing equipment
The activated carbon adsorption box (YQA all-in-one machine) is a VOCs waste gas treatment equipment developed by Eclear Environmental through years of research and engineering experience combined with the photocatalyst technology of university research institutions. It adopts a dual process combination of photocatalytic oxidation and activated carbon adsorption, as well as an integrated design concept.
Catalyzer
The Eclear catalyst is prepared using a unique flame combustion process, and the nanoparticles can complete the reaction in a high-temperature flame at 1800 ℃ for only 5-10 milliseconds. The short residence time allows the particle size of the nanoparticles to be accurately controlled within the range of 5-15 nanometers. At the same time, in-situ doping of elements such as Au, Ag, Mn, Fe, and Zn can regulate the absorption wavelength of nanoparticles and improve their absorption capacity, making the product nano photocatalyst have extremely excellent catalytic performance. Suitable for photocatalytic treatment of benzene containing organic waste gases and toxic and harmful waste gases such as ammonia, hydrogen sulfide, and methyl mercaptan emitted from industries such as printing, baking, painting, and garbage deodorization.
Adsorbent
The core of Eclear waste gas treatment system is Eclear dry gas phase filtration material. The Eclear dry gas phase filtration material is made using a proprietary special process and is spherical and porous in particle shape. The adsorption filter material removes odorous gases through chemical adsorption. When the collected odorous gases pass through the filter material, a chemical reaction occurs instantly when the filter material comes into contact with the odorous gas, thereby quickly and effectively removing the odorous gas. In the process of removing odorous gases, they are converted into harmless salts, which are irreversible. Once pollutants are removed from the environment, they cannot return to the air, effectively preventing secondary pollution of the air environment and ensuring safety and environmental protection.
