Application of Environmental Engineering in Diesel Engine Room

Jul 5, 2023 | China News | 0 comments

The diesel generator system is one of the emergency power supplies widely used in data centers. In the event of a municipal power outage, the UPS or high-voltage DC backup battery in the data center will enter the discharge mode to maintain the continuity of IT equipment power supply. At the same time, the diesel generator set configured in the data center quickly starts and completes the parallel operation to provide power guarantee for the entire data center. Reasonable configuration of diesel generator system determines the safety, reliability and long-term uninterrupted power supply of equipment. During the preliminary design and planning process of the data center, diesel generator sets should be configured as the emergency power supply guarantee for disaster recovery according to the capacity of the mains outside the data center. The bank data center also proves that the diesel generator set can become a strong backing to protect the disaster recovery capability of the data center.

Emergency Power System for Big Data Center

Diesel generator system is one of the widely used emergency power sources in data centers. In the event of a municipal power outage, the UPS of the data center or the high-voltage DC backup battery enters the discharge mode to maintain the continuity of the power supply of the river equipment. At the same time, the diesel generator set equipped in the data center quickly started to complete the well machine, and provided power to the small and medium-sized teaching buildings. The reasonable allocation of the Huafa system determines the safety, reliability and long-term uninterrupted power supply of the equipment. In the pre-planning process of the data center, according to the capacity of the mains outside the data center, a diesel generator set should be configured as a disaster recovery emergency power supply. The introduction of a diesel generator set needs to involve the scope of black smoke control.

Technical route for the treatment of exhaust black smoke (particulate matter) exceeding the standard

Cummins non-road engine black smoke purifier (D Pu Ji) is a new type of diesel engine exhaust treatment device independently developed by the Cummins technical team using the international advanced adsorption and chemical technology, and has all the intellectual property rights. Through multiple sets of metal The U-type alloy metal pellet trap composed of DF carriers connected in parallel, the core unit inside the trap adopts a withdrawable buckle design, when the interior of the trap reaches the preset incubation pressure limit due to excessive carbon deposition , the control unit controls the high temperature electromagnetic word to automatically open the bypass to ensure the normal operation of the unit. When the generator set is shut down and the purifier box cools down, the filter element unit can be pulled out flexibly and rinsed with tap water to complete the accumulation cleaning.

Brief introduction to black smoke control project of diesel generator set

Take a project of Huawei as an example: the equipment for the first phase of the project is nine backup 2000KW Cummins power diesel generator sets for exhaust black smoke control, and the equipment for the second phase project is nine backup 2000KW diesel generator sets for exhaust black smoke control. Both batches of projects use Cummins generator set metal black smoke purifier DF particle capture). From the early project site survey to the customized design, production and logistics of the solution, all the equipment for the first phase of the project has been installed, and now it is entering the installation stage of the black smoke purifier for the second phase of the project. The exhaust black smoke control of standby diesel generator sets is mainly to install an exhaust after-treatment device on the exhaust pipe of the diesel engine. The exhaust after-treatment system is also called a black smoke purifier, an exhaust purifier, and a soot processor. Yu-type purifier, using 409 or 304 body; high temperature 500C electric media valve, as well as bypass pipe and core, suitable for common power 50kw~2500KW, suitable for various international and domestic brands, for cold start of oil generator sets The first black smoke and the pollutants emitted during the operation process, PM particulate matter, Ringelmann blackness below the first level.

In view of the use characteristics of the standby generator, Cummins has adopted a withdrawable unit design, which is convenient for disassembly, cleaning and regeneration. Compared with the traditional high-temperature furnace combustion or high-pressure air back blowing on the market for regeneration, it has great advantages. No need for high-temperature combustion regeneration, ordinary tap water cleaning, truly zero energy consumption, zero secondary pollution. Easy installation, low-altitude emission, not occupying the ground of the machine room, long service life (same life as the diesel engine), convenient maintenance and other remarkable features, and the comprehensive calculation is low in investment cost.
