Abstract

The invention discloses a series heat exchanger radioactive waste gas cooling system in the technical field of waste gas cooling equipment, THE series heat exchanger radioactive waste gas cooling system comprises two groups of gas-water heat exchangers, wherein the air inlet of the left gas-water heat exchanger is connected with a waste gas inlet pipeline, the air outlet of the left gas-water heatexchanger is communicated with the air inlet of the right gas-water heat exchanger, the water inlets of the two gas-water heat exchangers are both communicated with a cooling water inlet pipeline, and the water outlets of the two gas-water heat exchangers are both communicated with a cooling water outlet channel. The inner cavity of a water tank is respectively connected with the cooling water outlet channel and the cooling water inlet pipeline through a first water pump and a second water pump, so that the circulation utilization of cooling water is realized, heat conversion is continuouslycarried out twice, efficient cooling is realized, radioactivity detection is carried out after reaching the temperature, and if the detected radioactivity does not reach the standard, heat exchange cooling is carried out again, and discharging is performed until the radioactivity reaches the standard, so that waste gas temperature meets the technical design requirements of the system, the coolingeffect is good, and the reliability of the system is improved.

Description

technical field [0001] The invention relates to the technical field of waste gas cooling equipment, in particular to a radioactive waste gas cooling system with serial heat exchangers. Background technique [0002] The power source of nuclear power plants is the fission energy produced by nuclear fission. During the process of releasing energy through fission, a large number of fission products and activation products will be produced. Although in the safety design of the reactor, there are defense-in-depth shielding measures for the fuel cladding, the primary circuit boundary and the containment vessel, due to a small amount of damage to the fuel cladding under special circumstances, the normal leakage of the primary circuit and the reactor safety facilities connected to the primary circuit A small amount of leaks from nuclear auxiliary facilities, maintenance activities in controlled areas, etc. will generate radioactive waste. When the fuel cladding is damaged during nor...
