Description
Technical field
The utility model is related to pressure vessel and equipment technical field, and in particular to one kind is used for pressure vessel in chemical industry
Rupture disk back pressure exhaust system.
Background technology
In chemical industry, the use of pressure vessel is more universal, for any pressure vessel that may occur superpressure and
Safe pressure relief device should be all set on non-pressure vessel.Rupture disk is a kind of conventional safe pressure relief device, and its principle is by dress
Put element（Rupture disk）Fracture and discharge material, with sealing property preferably, pressure release reaction is very fast and gas in it is contained
The advantages of dirt influences smaller to it, and can be used on low pressure, medium and high pressure container, it is applied widely.
It is big that rupture disk outlet in workshop on each pressure vessel is generally collected to a house steward directly discharge by enterprise
Gas, or enter processing system.But, if superpressure causes rupture disk to rupture after pressure release in a certain container, the thing that container is released
Material can be accumulated by the pipeline of connection in the rupture disk exit of other reactors, form back pressure, add container rupture disk and break
Split pressure, when in container occur superpressure when, rupture disk can not according to setting pressure disruption, pressure can continue in container accumulate
It is tired.When container internal memory is placed with poisonous, harmful or inflammable and explosive material, these materials may at the airtight and watertight padding of container or
Weak link leaks to scene at pad etc., causes personnel to be poisoned or Fire explosion, causes serious casualty situations.
Utility model content
For the shortcoming or deficiency of above-mentioned prior art, the technical problems to be solved in the utility model is to provide a kind of pressure
The rupture disk back pressure exhaust system of container, the system it is simple in construction, easy for installation and safe and reliable.
In order to solve the above technical problems, the utility model has following composition：
A kind of rupture disk back pressure exhaust system of pressure vessel, including it is installed on the explosion at the exhaust outlet of pressure vessel
Piece and bleeder, the rupture disk back pressure exhaust system also include connecting tube and discharging tube；The connecting tube be located at rupture disk and
Between bleeder, the outlet respectively with rupture disk of its entrance and exit and bleeder are connected；One end of the discharging tube
Connecting tube is installed on, the other end is connected with processing system.
The discharging tube is provided with discharging valve.
Between the outlet of the entrance and rupture disk of the connecting tube and between the outlet of connecting tube and bleeder,
To be detachably connected.
The connecting tube is located above rupture disk at 250mm to 350mm position.
The bleeder is connected by discharge manifold with processing system.
Compared with prior art, simple in construction, cost of the present utility model is relatively low, easy for installation and safe and reliable, can
Ensure pressure vessel the normal use of security leak device rupture disk on the basis of, it is to avoid other pressure vessel pressure releases and produce
Back pressure influence, with extensive market application foreground.
Brief description of the drawings
Fig. 1：The structural representation of the utility model rupture disk back pressure exhaust system.
Embodiment
The technique effect of design of the present utility model, concrete structure and generation is made furtherly below with reference to accompanying drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
As shown in figure 1, a kind of rupture disk back pressure exhaust system of pressure vessel, including rupture disk 1, connecting tube 2, discharging tube
3 and bleeder 5；Rupture disk 1 is installed at the exhaust outlet of pressure vessel 6, and bleeder 5 passes through discharge manifold and processing system
System is connected.
Connecting tube 2 is located between rupture disk 1 and bleeder 5, and its entrance and exit is removably communicated in explosion respectively
The outlet of piece 1 and bleeder 5.
Discharging tube 3 is used for the material of releasing for discharging the exit of rupture disk 1, and its one end is installed on communicating pipe 2, the other end and place
Reason system is connected；The discharging valve 4 that connecting tube 3 is turned on and off provided with control discharging tube 3.In the present embodiment, connecting tube 2
At the top 250mm to 350mm of rupture disk 1 position.
After overpressure relief occurs for a certain pressure vessel 6 in workshop, the row that the material that the pressure vessel is released passes through connection
Put house steward and bleeder 5 enters the exit of rupture disk 1 of other pressure vessels；At this moment, putting for other pressure vessels 6 is opened net
Valve 4, the material released is collected to processing system by discharging tube 3, so as to eliminate the back pressure influence produced because releasing material.
According to the teaching of the present embodiment, other the utility model protection models can be achieved in those skilled in the art completely
Enclose interior technical scheme.
