Huawei Group, as a globally renowned enterprise with numerous employees, has a large scale of catering supply in its canteens. However, with the increase of canteen operation time and the continuous expansion of catering business, the problem of oil fume has gradually become prominent. Recently, there have been some issues with the oil fume emissions from Huawei Group canteens. The concentration of oil fume exceeds the standard, which not only affects the air quality inside the canteen and affects the dining environment for employees to a certain extent, but also poses potential pollution risks to the surrounding environment. Some oil fume purification equipment is aging, resulting in a decrease in purification efficiency and inability to meet the growing demand for oil fume treatment. Moreover, due to the diverse cooking methods and complex oil fume composition in the cafeteria, the problem of odor is also prominent, which has brought adverse experiences to employees and surrounding residents. These oil fume environmental issues urgently need to be addressed to ensure the health of employees and the sustainable development of the enterprise, while meeting environmental protectionrequirements.

一、JINJIELI connects with Huawei Group to undertake bidding for major projects

1、Preliminary preparation and research

After learning about the bidding information for Huawei Group's oil fume purification project, JINJIELI Environmental Protection quickly formed a professional project team. The team members first gained a deep understanding of the basic situation of Huawei Group, including the size of the enterprise, the distribution of canteens, and the number of diners. At the same time, a detailed study was conducted on the environmental policies and standards in the region where Huawei Group is located to ensure that the scheme design meets relevant requirements. Subsequently, technical personnel were arranged to conduct on-site research at Huawei Group's cafeteria, conducting a detailed survey of the kitchen layout, number and type of stoves, ventilation system, and collecting relevant data on oil fume emissions to provide a basis for developing accurate oil fume purification plans.

2、Scheme design and optimization

Based on the research results, JINJIELI Environmental Protection has carefully designed a set of oil fume purification solutions for Huawei Group. Considering Huawei Group's high requirements for quality and performance, advanced multi-stage oil fume purification technology has been selected in the solution, which can efficiently remove particulate matter, oil, and odors from the oil fume, ensuring that the purification efficiency meets high standards. Based on the characteristics of oil fume generation in different areas of Huawei Group canteen, plan the layout of equipment and air volume distribution reasonably to achieve the best purification effect. During the design process, continuous discussions and optimizations are conducted with technical experts and engineers within the company to ensure the scientific, rational, and feasible nature of the plan. At the same time, we pay attention to the cost-effectiveness of the plan, while ensuring quality, we strive to reduce equipment procurement and installation maintenance costs as much as possible, and provide Huawei Group with cost-effective solutions.

二、Purification project implementation (300000 air volume)

1、Equipment procurement and customization

After winning the bid, JINJIELI Environmental Protection immediately carried out equipment procurement and customization according to the requirements of the plan. Cooperate with high-quality suppliers to ensure reliable quality of raw materials and components for equipment. According to the actual needs of Huawei Group's cafeteria, personalized customization of oil fume purifiers and deodorizers is carried out, such as the appearance size and interface form of the equipment, to ensure that the equipment can perfectly match the existing facilities of the cafeteria. During the equipment production process, strict quality control standards are implemented, and each device is rigorously tested and debugged to ensure stable performance and compliance with design requirements.

2.Installation and Debugging

After the equipment arrived, JINJIELI Environmental Protection quickly organized a professional installation team to enter the Huawei Group cafeteria. The installation team strictly follows the construction specifications and safety standards to ensure that the equipment is installed firmly, the pipeline connections are tight, and the electrical wiring is correct. During the installation process, closely cooperate with the cafeteria management and engineering technicians of Huawei Group to promptly solve any problems that arise and ensure the smooth progress of the installation work. After installation, comprehensive debugging work is carried out to test and optimize various performance indicators of the equipment, ensuring that the equipment operates in the best state and achieves the expected oil fume purification effect. At the same time, provide equipment operation and maintenance training to relevant personnel of Huawei Group, so that they can proficiently master the usage methods and daily maintenance points of the equipment.

3.Acceptance and delivery

After a period of trial operation, JINJIELI Environmental Protection invited Huawei Group and relevant environmental departments to conduct project acceptance. The concentration of oil fume emissions was detected by professional testing equipment, and the results showed compliance with national environmental standards. At the same time, a comprehensive evaluation was conducted on the operational stability, purification effect, and after-sales service of the equipment, and Huawei Group expressed satisfaction with the implementation effect of the project. JINJIELI Environmental Protection has officially delivered the oil fume purification project to Huawei Group and provided a detailed project acceptance report and after-sales service manual. After the project delivery, JINJIELI Environmental Protection will continue to maintain close contact with Huawei Group, conduct regular follow-up visits, promptly solve problems that arise during equipment operation, and provide long-term stable after-sales service support for Huawei Group.

Through the efforts of JINJIELI Environmental Protection, the oil fume environment in Huawei Group's cafeteria has been significantly improved, creating a fresh and comfortable dining environment for employees, while also making positive contributions to the company's sustainable development and environmental image establishment.
