Problems solved by technology

In order to achieve safe operation under various working conditions of nuclear power, the motor and power supply system of the ventilation system must also have certain reliability, that is, reach a certain nuclear safety level. In addition, it is necessary to install an automatic hydrogen monitoring and control system. This leads to a more complex system, which further reduces the reliability of the system
[0004] At present, there is no passive device to discharge heat and hydrogen at the same time, only the device that discharges heat separately, such as the patent application with publication number: CN104979023A, which can only discharge heat passively from the containment

Abstract

The invention discloses a passive exhaust device with storage batteries at intervals. The passive exhaust device comprises a hot pipe and an exhaust pipe, wherein the hot pipe is provided with an evaporation segment and a condensation segment, the exhaust pipe is provided with an air inlet and an exhaust hole, the evaporation segment of the hot pipe is arranged in the storage batteries, the condensation segment of the hot pipe is arranged in the exhaust pipe, the exhaust hole of the exhaust pipe is connected with the atmosphere, and the air inlet of the exhaust pipe is arranged above the storage batteries. Heat generated by the storage batteries is transferred to a lower part of a vertical segment of the exhaust pipe by the hot pipe, ambient air is heated, hot air rises and drives air near to a lower end part of the exhaust pipe to enter the exhaust pipe, the hot air is heated by the condensation segment of the hot pipe, then rises and sequentially passes through the vertical segment of the exhaust pipe and an outlet, hydrogen and heat which are generated by the storage batteries are timely discharged, so that a risk of hydrogen explosion is effectively prevented.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a passive exhaust device for storage battery compartments in nuclear power plants. Background technique [0002] As a DC power system, the battery of a nuclear power plant is the last protective barrier for the safety of the nuclear power plant. Its operating status and performance are decisive factors for the safe and stable operation of the DC system. my country's "Safety Requirements for New Nuclear Power Plants During the Twelfth Five-Year Plan Period" (draft for comments) requires that nuclear power plants should be able to maintain continuous cooling of the core within 8 hours of loss of off-site and on-site emergency AC power without causing reactor damage. In this case, the battery is a reliable power supply system, therefore, the battery has also become an important link to ensure safety. [0003] When the battery is charged, its electrolyte will decompose a large amount of...
