We are a small and medium-sized technology-based enterprise in Hebei Province, a small provincial-level technology giant, and a small and medium-sized technology enterprise (stock code: 201913010408000116). The company is located in Shijiazhuang City, Hebei Province, with a registered capital of 10 million yuan and an area of 30 acres. The company has more than 80 employees, including 2 professor-level senior engineers, 10 senior titles, 1 doctorate, 5 masters, and employees with college degree or above. It accounts for 40% of the total number of employees. The company undertook to build the "Shijiazhuang City Gaseous Industrial Pollutants Purification Equipment Engineering Technology Research Center", and the Hebei University of Science and Technology School of Environmental Engineering jointly established the "Air Pollution Control Research Center", and is a member of the "Volatile Organic Compounds and Odor Pollution Control Technology Engineering Research Center" unit. We make full use of the advantages of enterprises and universities in the fields of scientific research and development, testing and verification, equipment design and manufacturing, and engineering implementation, and use advanced environmental protection technology to meet the individual needs of customers in different industries. We have undertaken 4 science and technology projects above the municipal level and more than 20 authorized patents. We are a member unit of the Internal Combustion Engine Emission Aftertreatment Committee of the China Internal Combustion Engine Industry Association, a member unit of the Distributed Energy Committee of the China City Gas Association, a member unit of the Shanxi Gas Power Generation Association, and Hebei Province Member of the Environmental Protection Association.
We integrate R&D, manufacturing, installation, sales, and service, with a R&D team and experienced production, engineering and technical personnel. In terms of core equipment research and development, we have independent product research and development capabilities. Through the introduction of international advanced technology, we have mastered a number of core technologies and independent intellectual property rights; in terms of technical services, we can perform for designers, bidders, investors, supervisors, and owners. Technical Advisory Services. Provide consultation, analysis, research, survey, site flue gas parameter measurement, layout design in the early stage of the project; mid-term plan design; late-stage project construction, after-sales service and other whole-process localization services. A full-time after-sales service team can provide products and products nationwide. Engineering after-sales service; in terms of production, in addition to our own large-scale equipment production base, we are also a manufacturer of coated denitrification catalysts, and have the ability to produce denitrification catalysts that meet the requirements of national standards (including design, manufacturing, and testing capabilities). The coating-type denitrification catalyst has an annual production capacity of more than 1000m3; the formula and process have completely independent intellectual property rights, including low-temperature, medium-temperature vanadium-based, high-temperature-resistant modified vanadium-based, and iron-based molecular sieve high-temperature formulations. We have an in-depth grasp of the SCR denitration mechanism, and can adjust the catalyst formulation according to the actual needs of different users (flue gas working conditions, ash composition, etc.); in terms of engineering construction, we have the ability to contract EPC turnkey projects. Over the past 19 years, it has served more than 800 companies and has successful cases in many fields.
We have introduced international advanced technology, self-developed SCR denitrification system, equipped with high-performance V-Ti or Fe-Zeolite catalyst, which has a wide applicable temperature range and long life. It can maintain a good purification rate in the temperature zone of 180-600℃. Through flue optimization, guide device optimization, ammonia injection optimization, ammonia nitrogen mixing device optimization and other key SCR denitration flow field technologies, we greatly reduce system resistance, improve denitrification efficiency, extend catalyst life, and reduce ammonia slip. It can achieve ultra-low emission of nitrogen oxides NOx<10mg/Nm3 (purification rate as high as 98%), and achieve the purpose of deep denitrification.
The internal combustion engine denitration system is suitable for GE Jenbacher, Cummins, Waukesha, Mannheim, Carter, Deutz, Shengdong, Jichai, Zichai and other branded units with a single unit below 10MW and a parallel system below 25MW. %-110% full load use. The catalyst's unique N+1 layer design and reserve a spare layer can meet the more stringent emission requirements in the future. The intelligent NOx closed-loop control system configured in the system can dynamically adjust the amount of reductant injection in real time according to actual emission conditions, and reduce operating costs as much as possible on the basis of meeting local emission online monitoring standards. Through a number of low-wattage electricity cost optimization designs, the economic burden of the owners is greatly reduced, which is more in line with China's national conditions.
In view of the differences in the emissions of data center standby units and the differences in third-party acceptance scenarios, combined with the monthly start-up of the units, emergency power generation and other scenarios, we can provide different combination systems such as DOC+DPF+SCR, DPF+SCR, SCR, DPF, etc., to meet the needs of data center backup The units are installed in batches.
In view of the uneven flow field of gas turbine exhaust, high CO and HC content, high temperature, ultra-short ammonia injection, etc., we have launched a gas turbine waste heat boiler SCR denitration system suitable for gas turbines such as Solar and GE. brand.
We also provide explosion-proof, prototype, marine, containerized, waste heat denitrification integrated SCR denitrification system, which can meet the demanding environment such as gas explosion-proof areas, plateau low pressure, marine environment, cold winter outdoor layout, and small space waste heat recovery and simultaneous denitration. Require. Hanlan Environmental SCR denitrification system has been used in many domestic and foreign gas distributed energy, landfill gas power stations, kitchen waste biogas power stations, calcium carbide power stations, coke oven gas power stations, gas power stations, blue carbon gas power stations, and the “Belt and Road Initiative”. "Successfully applied in overseas power stations, data center backup units, and oil and gas boiler projects. We have rich experience in domestic, overseas, gas explosion-proof areas, islands and reefs, and drilling platforms. At present, the number of cases is at the forefront of the industry in China. At the same time, we have strategic cooperation with many large domestic OEMs to jointly develop supporting products.
Through our innovative SCR denitrification technology, "one-stop solution" custom design capability, unique core catalyst formula and catalyst production line, complete urea preparation system and other peripheral product lines, low-cost maintenance spare parts and fast response local after-sales service, we continue to reduce investors' investment costs in environmental protection equipment and post-operating costs, shortening the payback period. Our SCR denitrification system can completely replace foreign imported products, making environmental protection equipment no longer a luxury in the gas distributed energy industry, allowing investors, design institutes and owners to save money, heart and effort in the environment of ever-tightening environmental protection policies.
