Year 1967
In order to solve the pollution of cyanide-containing electroplating wastewater to the drinking water source of Donghu Lake, the company began to develop the sodium hypochlorite generator by electrolyzing brine.
Year 1975
The first sodium hypochlorite generator by electrolyzing brine, which was using graphite electrodes, was successfully developed and won the National Science Congress Award in 1978.
Year 1981
The first sodium hypochlorite generator by electrolyzing brine with the introduction of English CHLOROPAC technology passed the appraisal of the Ministry of Aviation Industry, marking the success of the localization of tubular electrode technology.
Year 1989
Six sets of DJL- 10 brine-type sodium hypochlorite generators developed for the circulating cooling water system of Jamshoro Power Station in Pakistan were successfully delivered and operated, marking the first time that the first self-developed tubular electrode brine-type sodium hypochlorite generator went out of China for the first time, and the first time that it was applied to the circulating cooling water system of the power station.
Year 1990
The national standard GB12176- 90 "Sodium Hypochlorite Generator", which was drafted by North China Municipal Engineering Design & Research Institute Co., Ltd. and Wuhan Instrumentation Factory of the Ministry of Aerospace Industry, was promulgated and implemented in July 1990, and the company became the earliest drafting unit of the national standard "Sodium Hypochlorite Generator".
Year 1991
The 3 sets of LHB- 15 seawater-type sodium hypochlorite generators developed by the company for the cooling circulating water system of Qingdao Power Plant adopt bipolar electrode technology, which is the first time that this technology is applied to the circulating cooling water system of the domestic power station, and it is also the first seawater-type sodium hypochlorite generating project in China.
Year 1995
The company has developed 2 sets of LHB- 70 seawater-type sodium hypochlorite generators for the cooling circulating water system of Qingdao Power Plant Expansion Project, which adopts multivariate N-type nano-crystalline anode coatings, adds uniquely-designed intermediate dehydrogenator, and has great innovations in the distribution system and control system, which signifies that the sodium hypochlorite generator developed by the company has reached the world's advanced level.
Year 1997
The two sets of LYB- 10 brine-type sodium hypochlorite generators produced by the company for the UCH power station project of American GE in Pakistan passed the acceptance and were successfully delivered, marking the company's full convergence with the international level of quality management and engineering management.
Year 2001
The company developed and produced 2 sets of LHB- 36 seawater-type sodium hypochlorite generator for Chinese Dalian Petrochemical Company, since then the company's sodium hypochlorite generator has entered the petrochemical field.
Year 2008
The company developed and produced 2 sets of LHB- 225 seawater-type sodium hypochlorite generator for Harbin Electric International Engineering Co., Ltd. for Indonesia Paiton Power Station Project, which was formally put into operation in 2010, and is the largest seawater-type sodium hypochlorite generator with the largest yield in China.
Year 2010
The company produced 4 sets of LHB- 130 electrolyzed seawater-type sodium hypochlorite generator for Saudi Arabia Labig sub-critical oil-fired unit project of SEPCO3. The design and manufacture of this project implement ASME, ASTM and other international standards, and its successful delivery verifies the company's internationalized design and production capacity.
Year 2015
The company designed and manufactured 3 sets of LHB- 43 seawater-type sodium hypochlorite generator for American Optimum, and in August 2016, the delivery was completed. The whole system of this project adopts skid-block design, which greatly reduces the workload of on-site installation and commissioning, and effectively shortens the project cycle. This is also the first time that the skid-block chlorine system is applied to engineering projects in China.
Year 2016
The 2 sets of LYB- 50 and 2 sets of LYB- 60 brine-type sodium hypochlorite generators produced by the company for HEI's Pakistan BHIKKI and BALLOKIpower station projects were completed and delivered in June 2016, which solved the technical problems of brine-type sodium hypochlorite generators used in high-temperature climatic conditions, and also is the largest brine-type sodium hypochlorite generator in the country with the largest yield of the brine-type generator that has been put into operation. Sodium hypochlorite generator.
Year 2019
The LYB( W) type sodium hypochlorite generator researched and developed by the company obtained the license of drinking water disinfection equipment, and then provided the models of sodium hypochlorite generator of LYB( W) - 3, LYB( W) - 2, LYB( W) - 15 to Hunan Changde Water Plant, Hubei Fuzishan Water Plant, Guizhou Beijiao Water Plant respectively, and the successful accepting of the above equipment marked that the company had successfully stepped into another new market.
Year 2023
The company's self-developed Alkaline Type Hydrogen Generator completed the performance acceptance test. The success of this test not only verified the rationality, safety and stability of the equipment's design, but also marked the company's important progress in the field of new energy technology.
