Explosion-proof treatment method of bared conductor of sodium cyanide cracking furnace

Abstract

The invention discloses an explosion-proof treatment method of a bared conductor of a sodium cyanide cracking furnace. In the process of producing sodium cyanide by cracking light oil, a part of electrified conductors is bared in the explosive gas environment; once gas is leaked in the production process, explosion is easily caused. According to the explosion-proof treatment method disclosed by the invention, after adopting the measures of locally ventilating through positive pressure and reducing the regional explosive district environment, the explosion-proof problem of non-explosion-proof electric equipment can be solved; continuous and safe operation of non-explosion-proof facilities in the production process and personal safety of operation and routing inspection people can be ensured; the property safety of enterprises is also ensured; the safety in the production process is increased, and therefore, good economic benefits are brought about for enterprises.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to the explosion-proof problem of electrified facilities in the production process of sodium cyanide; the invention can also be used for the explosion-proof design of electrified conductors in the explosion zones of other similar projects. Background technique [0002] Sodium cyanide is a highly toxic chemical. In the production of light oil cracking process, there are flammable and explosive media such as light oil, hydrogen cyanide, hydrogen, and liquid ammonia. It belongs to a typical explosive gas environment, and the light oil cracking furnace The power supply is a low-voltage, high-current facility with a voltage of 250-300V and a current of 4000-5000A. During the process of connecting the electrodes of the electric furnace, some live conductors are exposed: mainly including the connection between the flexible cable and the copper bar and the hoop, and the Due to the presence of ...

[0002] Sodium cyanide is a highly toxic chemical. In the production of light oil cracking process, there are flammable and explosive media such as light oil, hydrogen cyanide, hydrogen, and liquid ammonia. It belongs to a typical explosive gas environment, and the light oil cracking furnace The power supply is a low-voltage, high-current facility with a voltage of 250-300V and a current of 4000-5000A. During the process of connecting the electrodes of the electric furnace, some live conductors are exposed: mainly including the connection between the flexible cable and the copper bar and the hoop, and the Due to the presence of strong arcs at the joints of hoops and electrode rods, dangerous phenomena such as explosions often occur during the production process, which may further cause explosions, posing a great safety hazard

At present, manufacturers at home and abroad have not taken effective measures against the above situation, which poses a great security threat to the lives of relevant personnel such as operations and inspections, as well as to corporate property.
