Explosion refuge safety house for thermal power plant

Abstract

The invention discloses an explosion refuge safety house for a thermal power plant. The explosion refuge safety house comprises an explosion-proof outer shell and a compression-resistant outer shell,the pressure-resistant outer shell is movably installed at one end of the explosion-proof outer shell, a pressure-resistant inner shell is welded to the surface of one end of the explosion-proof outershell, a rescue capsule is fixedly installed between the pressure-resistant inner shell and the explosion-proof outer shell through reinforcing ribs, and a water curtain mechanism is fixedly installed on one side of the outer wall of the rescue capsule through a connecting rod and comprises an upper end cover and a lower end cover. According to the invention, a gas purification mechanism and thewater curtain mechanism are installed, the cleanliness of gas entering the rescue capsule can be ensured, therefore enough oxygen can be provided for the interior of the rescue capsule, the temperature of the air entering the rescue capsule is low, the temperature in the rescue capsule is not increased due to the high air temperature, the requirement for external oxygen supply can be met, life danger caused by insufficient oxygen is avoided, and therefore the survival time of trapped people in the rescue capsule can be prolonged.

Description

technical field [0001] The invention relates to the technical field of thermal power plants, in particular to an explosion refuge safe house for thermal power plants. Background technique [0002] A thermal power plant, referred to as a thermal power plant, is a factory that uses combustibles (such as coal) as fuel to produce electrical energy. Its basic production process is: when the fuel is burned, the water is heated to generate steam, the chemical energy of the fuel is converted into thermal energy, the steam pressure drives the steam turbine to rotate, the thermal energy is converted into mechanical energy, and then the steam turbine drives the generator to rotate, converting the mechanical energy into electrical energy. The prime mover is usually a steam engine or a gas turbine, and in some smaller plants, an internal combustion engine may also be used. They all generate electricity by using the pressure drop in the process of turning high-temperature and high-pressu...

Problems solved by technology

[0003] However, most of the explosion shelters currently on the market have relatively simple functions and are very inconvenient to use. Most of the traditional explosion shelters are sealed and require oxygen cylinders for support. When trapped for too long, After the oxygen in the oxygen cylinder is exhausted, there will be a danger of insufficient oxygen, which will easily lead to life safety issues. Moreover, the traditional explosion shelter does not have a buffer and pressure-resistant shell, and the impact caused by the explosion is directly borne by the shell of the cabin. The ability to resist pressure is weak, and in extreme cases, it may not be able to withstand a large impact, and the internal equipment is also easily damaged
