Recently, the Office of the Ministry of Ecology and Environment issued the "2022 List of Technology Supporting Units for the National Advanced Pollution Control Technology Catalog (Water Pollution Control Field)". Hezhongsi (Beijing) Environmental Engineering Co., Ltd. was included in this catalog with its "Flue gas desulfurization wastewater membrane concentration + mechanical vapor recompression (MVR) evaporation crystallization technology".

 

MVR evaporation crystallization technology is a highly efficient evaporation technology that can reduce evaporation and distillation costs, reduce equipment footprint, improve equipment automation capabilities, and improve the quality of industrial products. Compared with traditional evaporators, it not only has significant energy-saving and environmental protection advantages, but also reduces operating costs, and is the best upgrade system for traditional multiple-effect evaporators. With the country's emphasis on environmental protection and energy conservation and emission reduction and the introduction of relevant policies, MVR evaporative crystallizers will inevitably replace traditional evaporators, playing a huge role in national environmental protection, energy conservation and emission reduction, and sustainable development. It also brings practical social and economic benefits to enterprises.

 

"Evaporation crystallization technology for resource reuse of desulfurization wastewater" adopts pretreatment + membrane concentration treatment + evaporation crystallization treatment technology. Its core technology is the use of mechanical vapor recompression evaporation crystallization system technology. This technology reuses the energy of the secondary steam of the evaporator to reduce the demand for external energy. Its working process is that low-temperature steam is compressed by a compressor, the temperature and pressure are increased, the enthalpy is increased, and then it enters the heat exchanger for condensation to fully utilize the latent heat of the steam.

 

The 2022 "National Advanced Pollution Control Technology Catalog (Water Pollution Control Field)" is to implement the requirements of the "Environmental Protection Law of the People's Republic of China", the "Water Pollution Prevention and Control Law of the People's Republic of China", and the "Opinions of the Central Committee of the Communist Party of China and the State Council on Deepening the Fight against Pollution", giving full play to the role of advanced technologies in water pollution control. It is a catalog of pollution control technologies with advanced technical level, significant environmental benefits, and economic feasibility, launched by the Ministry of Ecology and Environment based on the key and hot areas of environmental pollution control. It represents mature technologies that have been proven in engineering practice and are encouraged for promotion and application.

This selection is both a high level of national recognition of this technology and full affirmation of Hezhongsi's long-term commitment to technological innovation and research and development.

In the future, Hezhongsi will continue to focus on the industry's shortcomings and weaknesses, actively expand industry areas, adhere to the path of innovation, develop more practical new products and technologies, achieve high-quality development, focus on deepening the "specialized, refined, distinctive, and new" field, create more value for customers, grow together with customers, and achieve a win-win situation for both enterprises.
