Description
Technical field
The utility model belongs to high-pressure hydrogenation reaction discharge operating technology field, and in particular to a kind of high-pressure hydrogenation reaction kettle
Protecting against shock discharge system.
Background technique
High-pressure hydrogenation discharge generallys use control valve aperture control blowdown pressure and speed at present, due to hydrogenation reaction kettle
Pressure 6.0Mpa or more in kettle when discharge causes very big impact force to discharge valve and pipeline due to pressure height, and sound is big,
Vibration is big, blow-off valve because pressure difference after and before the valve it is big in the case where often open and close, one side blowdown pressure controls by rule of thumb, discharge pressure
Power is unstable, and another aspect valve sealing element is damaged because long-term friction is easy fatigue, needs to be replaced frequently, drainage line and connection
Blow-down drum be easily damaged.Someone substitutes hand valve using automatic control adjustable valve, but still there are problems that valve seal rapid wear often changes.
Utility model content
For the purpose of this utility model in order to solve the problem in above-mentioned background technique, it is simple to provide a kind of structure,
It is able to solve discharge valve and is easy impaired problem, while the high pressure for protecting the blow-down drum of drainage line and connection not damaged
Hydrogenation reaction kettle protecting against shock discharge system.
The technology employed by the present utility model is a kind of high-pressure hydrogenation reaction kettle protecting against shock discharge system, including it is anti-
Kettle is answered, manual switch valve, pneumatic on-off valve, check-valves are disposed on the discharge pipe of the reaction kettle；It is described pneumatically to open
It closes and is provided with restriction orifice between valve and check-valves.
Bore dia on the restriction orifice is 10-20mm, reduces impact force when discharge, solves discharge valve and is easy
Impaired problem, while protecting the blow-down drum of drainage line and connection not damaged.
Blow-down drum is removed in the check-valves connection.
The discharge pipe includes inner and outer wall, is provided with vacuum layer between the inner and outer wall, on the inner wall
It is provided with helical structure.
The utility model has the beneficial effects that
The utility model structure is simple, and manual switch valve is normally opened, and when maintenance uses, and when discharge, pneumatic on-off valve is opened, kettle
Interior pressure 6.0MPA, feed liquid are discharged by pressure, and feed liquid passes through the current limliting depressurization of restriction orifice, pressure after orifice plate
0.4MPA, pressure is lower after discharge orifice plate and pressure is stablized, and reaches reduction vibration, and drainage line and blow-down drum are rushed in reduction
It hits, ensure that safety in production.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
A kind of high-pressure hydrogenation reaction kettle protecting against shock discharge system, including reaction kettle 1, on the discharge pipe 2 of the reaction kettle 1
It is disposed with manual switch valve 3, pneumatic on-off valve 4, check-valves 5；It is provided between the pneumatic on-off valve 4 and check-valves 5
Restriction orifice 6.
Bore dia on restriction orifice 6 described in the utility model is 10-20mm, and when reaction kettle discharge, material is gentle
Body, which flows through orifice flow, to be reduced, and can also reduce to the impact force of pipeline, it is impaired to solve the problems, such as that discharge valve is easy, simultaneously
Protect the blow-down drum of drainage line and connection not damaged.
Blow-down drum 7 is removed in the connection of check-valves 5 described in the utility model.
Discharge pipe 2 described in the utility model includes inner wall 8 and outer wall 9, is provided between the inner wall 8 and outer wall 9
Vacuum layer 10 is provided with helical structure 11 on the inner wall 8, reduces impact force simultaneously to a certain extent.
The principles of the present invention:
Manual switch valve is normally opened, and when maintenance uses, and when discharge, pneumatic on-off valve is opened, pressure 6.0MPA in kettle, and feed liquid is logical
Excess pressure discharges, and feed liquid is by the current limliting depressurization of restriction orifice, pressure 0.4MPA after orifice plate, pressure after discharge orifice plate
Lower and pressure is stablized, and reaches reduction vibration, reduces the impact to drainage line and blow-down drum, ensure that safety in production.And
By the setting of discharge pipe, while impact force is reduced to a certain extent.
Although the utility model has been described by way of example and in terms of the preferred embodiments, it is not intended to limit the utility model, any
Person skilled in the art can do various change and modification, therefore this without departing from the spirit and scope of the utility model
The protection scope of utility model should subject to the definition of the claims.
