Description

Automatic distribution method for leakage liquid and fire-fighting wastewater Technical Field The invention relates to the technical field of diversion, in particular to an automatic diversion method for leakage liquid and fire-fighting wastewater. Background With the rapid development of high-density computing and artificial intelligence technology, liquid cooling technology has become a mainstream scheme for heat dissipation of data centers. The cooling medium (such as glycol aqueous solution, fluoridation solution and the like) is usually toxic or harmful to the environment, and the cooling medium must be tightly collected after leakage, so that the discharge is forbidden. Meanwhile, the data center machine room is used as a key fireproof area, an automatic water spraying fire extinguishing system is required to be arranged, and drainage is required to be smooth so as to prevent waterlogging. This creates a fundamental contradiction between the environmental entrapment requirements and fire drainage requirements. The prior art generally adopts an electrically controlled valve switching scheme to cope with the contradiction. The scheme generally comprises a large leakage liquid collecting tank, wherein a water inlet of the large leakage liquid collecting tank is connected with a machine room drain pipe network, and a water outlet of the large leakage liquid collecting tank is isolated from a municipal drain pipe through an electric valve (such as an electric butterfly valve and a ball valve). Normally, the valve is closed, and the leakage liquid is led into the collecting tank for temporary storage. When the fire alarm system is triggered, the control system sends an opening signal to the electric valve to open the electric valve, so that a discharge channel is provided for fire-fighting wastewater. However, how to judge whether the leaked liquid or the fire-fighting wastewater is collected by the collecting tank, and once the valve is opened by mistake, toxic leaked liquid is directly discharged into a municipal pipe network, so that serious environmental protection accidents are caused.
