Is it necessary to have a detonation tube and a receiving tank behind the blast disc? Is there any specification that specifies requirements? Those who know please leave a message.
The outlet pipeline of the burst disc should lead to a safe location or a closed recovery system. Leading it to a safe location is primarily aimed at protecting operators and equipment, while directing it to a closed recovery system is intended for highly toxic materials, strongly corrosive materials, and valuable materials, in order to prevent poisoning, personal injury, and economic losses resulting from material leaks. Reference can be made to HG/T 20570.2 \"Installation and Selection of Safety Valves\" (sections 13 on the design of safety valve outlet pipelines), as well as HG/T 20570.3-95 \"Installation and Selection of Pressure Relief Discs\" (section 4 on the installation of pressure relief discs, item 4.0.4, and section 9 on the combined use of pressure relief discs and safety valves).
There aren’t any strict requirements; we don’t install bursting discs here at all.
There are no specific requirements, but in principle it is necessary to ensure that excretion takes place safely, so as to avoid harming people and prevent the accumulation of flammable or toxic gases indoors
It is set according to the actual conditions of each production section: 1. In the gas generation section of a certain company, protective devices are installed on the main air pipes as well as on the burners (air blower recovery furnaces), to prevent injury to people or damage to process pipelines, electrical circuits, instruments, etc., in the event that the explosion-proof panels come into action； 2. The downward explosion-proof plate is simply protected by a “cross” shape welded with iron behind the blind plate.
Depending on the toxicity of the material, its value, and the safety aspects related to its spraying, it may be necessary to install detonation tubes and receiving tanks. On the one hand, ensure safety to the greatest extent possible; on the other hand, reduce losses and minimize environmental pollution. The set of detonation tubes and receiving channels need to be calculated; the diameter of the detonation tubes must also be determined.
The explanation on the second floor is clearer; if highly toxic materials are involved, a treatment system for such materials should also be added.
