Abstract
The invention discloses a reactor safety control device which comprises a rupture disc device, a valve, a temperature sensor and pipes. The rupture disc device comprises a rupture disc installed in a clamping holder, a pressure releasing hole is formed in one side of the clamping holder, one end of the valve is connected with a reactor through one pipe, the other end of the valve is connected with one end of the rupture disc device, the other end of the rupture disc device is led to a discharging groove, and the temperature sensor is inserted on the pipe between the valve and the discharging groove and transmits signals to a central control room through a wire. According to the reactor safety control device, the valve can be closed after the rupture disc is ruptured, the reactor is still in the controllable state, and the safety of the production process and devices is guaranteed; the temperature sensor is additionally installed, anomalies can be timely found and processed, and losses can be reduced.
Description
Technical field
The invention belongs to reactor technology field, be specifically related to a kind of reactor safety control.
Background technique
At chemical industry, oil refining, metallurgy, light industry, reactor is a conventional equipment, for realization response process, if misoperation will have influence on safety, personal injury, manufacturing efficiency and quality etc. directly or indirectly.Gently cause rejection and waste, heavy lead to destructive disaster accident, to the safety measure of reactor, be generally to adopt rupture disk release, rupture disk is the safe pressure relief device for guaranteeing that the safe operation of pressurized container arranges, explosion under the temperature and pressure of regulation, release pressure, protection container can superpressure not cause the accident, similar with the principle of household pressure-cooker, after rupture disk breaks, change and need a period of time, reactor in the lower operation of negative pressure (vacuum), change rupture disk during this period of time in material in reactor can enter letdown tank along pipeline, cause very large loss, and after rupture disk breaks, uncontrollable inside reactor temperature, cause reactor temperature out of control, affect production process safety and device security, also sometimes cannot immediately judge whether rupture disk breaks.
Summary of the invention
For addressing the above problem, the invention discloses a kind of reactor safety control, the reactor in the lower operation of negative pressure (vacuum), can break post-reactor still in controllable state at rupture disk, reduces the loss.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of reactor safety control, it is characterized in that: comprise blasting piece device, valve, temperature transducer, pipeline, described blasting piece device comprises the rupture disk being arranged in clamp holder, clamp holder one side is provided with pressure relief vent, described valve is by pipeline one end coupled reaction device, the other end connects blasting piece device one end, the other end of blasting piece device leads to letdown tank, on the pipeline between valve and letdown tank, be inserted with temperature transducer, described temperature transducer produces signal to central control chamber by wire.
As a modification of the present invention, described valve housing adopts carbon steel, and internals are stainless steel.
As a modification of the present invention, described rupture disk is counter-arch shaped.
As a modification of the present invention, described valve is ball valve.
As a modification of the present invention, described temperature transducer is PT100 thermocouple.
As a modification of the present invention, the bursting pressure of described rupture disk is 0.37Mpa.
As a modification of the present invention, described clamp holder is stainless steel, and rupture disk surface is provided with ETFE film.
As a modification of the present invention, described rupture disk is metallic rupture disk.
The invention has the beneficial effects as follows:
A kind of reactor safety control of the present invention, can be after rupture disk breaks throttle down, reactor, still in controllable state, guarantees production process safety and device security; Reload temperature sensor, can note abnormalities in time and process, and reduces the loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Reference numerals list:
1, valve, 2, clamp holder, 3, rupture disk, 4, pressure relief vent, 5, pipeline, 6, temperature transducer, 7, central control chamber, 8, reactor, 9, letdown tank.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand following embodiment and only for the present invention is described, is not used in and limits the scope of the invention.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometrical center.
As shown in the figure, a kind of reactor safety control of the present invention, comprise blasting piece device, valve 1, temperature transducer 6, pipeline 5, described valve is ball valve, described temperature transducer is PT100 thermocouple, described blasting piece device comprises the rupture disk 3 being arranged in clamp holder 2, clamp holder 2 one sides are provided with pressure relief vent 4, described rupture disk is counter-arch shaped, than traditional domed rupture disk, it is good that it has anti-fatigue performance, during explosion, do not produce fragment and operation pressure and can reach more than 90% advantage of its minimum burst pressure, described rupture disk is metallic rupture disk, the bursting pressure of rupture disk is 0.37Mpa, described valve 1 is by pipeline 5 one end coupled reaction devices 8, the other end connects blasting piece device one end, the other end of blasting piece device leads to letdown tank 9, on the pipeline 5 between valve 1 and letdown tank 9, be inserted with temperature transducer 6, described temperature transducer 6 produces signal to central control chamber 7 by wire.
The present invention increased valve before rupture disk, while working at ordinary times in normally open, once pressure is excessive, rupture disk breaks after pressure release, can throttle down, vacuumize, make reactor still keep closed system, in controllable state, guarantee production process safety and device security; Reload temperature sensor, once rupture disk breaks, temperature transducer can detect temperature in pipeline sharply changes, central control chamber is reported to the police, and makes operator know that immediately rupture disk breaks, and can note abnormalities in time and process, avoid too much material to be discharged into letdown tank, reduce the loss.
Because reactor is generally used for chemical industry, oil refining, metallurgy, light industry, corrosivity is stronger, and valve 1 housing therefore of the present invention adopts carbon steel, internals are stainless steel, described clamp holder 2 is stainless steel, and rupture disk 3 surfaces are provided with ETFE film, and work can normally move.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned mode of execution, also comprises the technological scheme being comprised of above technical characteristics combination in any.
