Abstract

The invention discloses a method for minimizing a degree of an explosion of a steam boiler vessel and a device thereof. The device comprises a pressure vessel, a heater positioned in the pressure vessel, water, a water inlet and a steam outlet or a sewage outlet, wherein the water inlet and the steam outlet or the sewage outlet mutually communicate with the pressure vessel. The device is characterized in that at least between an inner wall of a heating part of the pressure vessel and an outer wall of the heater is filled with solid, high temperature resistant, high pressure resistant, good thermal conductivity and non-absorbent solid particles, and gaps between the solid particles are hydrophobic and vapor permeable. The solid particles are mixed with elastic particles or sheets which cancounteract thermal expansion and contraction of the solid particles, and a fence for blocking filling materials is arranged on the inner side of the water inlet or the sewage outlet and the steam outlet, and the particles extrude most of the water in the pressure vessel to reduce the water volume of the pressure vessel fully, and thus the explosion energy contained in the high temperature and highpressure water in the pressure vessel is reduced, and the degree of the explosion of the boiler vessel is minimized.

Description

technical field [0001] The invention relates to a safety method and a device for a steam boiler container, in particular to a method and a device for minimizing the explosion of a steam boiler container. Background technique [0002] Boiler is a kind of special equipment that withstands high temperature and high pressure and has the danger of explosion. Once it explodes, it will be extremely harmful and cause extremely serious consequences. According to statistics, from 1976 to 1987, there were 2,710 boiler explosions in China, killing 1,532 people and injuring 5,754 people. [0003] The boiler is a closed container with water and pressure. When the steam pressure in the boiler is greater than the tensile capacity of the boiler shell, an explosion accident will occur. When the boiler explodes, the steam drum ruptures, and the pressure in the boiler suddenly drops to the same pressure as the outside atmosphere. When the pressure drops, the high-pressure steam in the boiler e...
