Description
Technical field
The utility model relates to a kind of silver-colored formaldehyde safety devices.
Background technique
It is that methanol and oxygen carry out reaction generation formaldehyde, water and hydrogen, charging and matches in the production process of formaldehyde process by silver
The excessive of methanol is kept to participate in reaction than in.Therefore, it is necessary to ensure that the oxygen content ratio of system is low when oxidation reaction carries out
Below the explosive range of methanol and oxygen mixed gas；When oxygen content superelevation, high temperature or rupture pressure disc will occur for oxidator
The accident of explosion, at this time methanol gas will leak or air in a large amount of oxygen enter in oxidator, cause more serious two
Secondary disaster.
Moreover, being related to raw material, dynamic equipment, electrical, instrument failure in the continuous process of Formaldehyde Production, occurring
It is unbalance that proportion scale occurs in oxidation of formaldehyde device, causes oxidator abnormal high temperature occur, more seriously leads to the explosion of explosion rupture disk, at this moment
Time can threaten the safety in entire chemical industry region and the life safety of Field Force.
Summary of the invention
The purpose of this utility model is to overcome above deficiencies, provide a kind of silver-colored method that structure is simple, safe and reliable
Formaldehyde safety device.
The purpose of this utility model is achieved through the following technical solutions: a kind of silver formaldehyde safety device, including
Oxidator, oxidator are equipped with temperature sensor and rupture disk, and rupture disk is connected with detonating signal sensor, temperature sensor and
Detonating signal sensor is controlled by control system, and protective device further includes nitrogen buffer tank, and nitrogen buffer tank is connected with long-range control
Switch valve processed, remote control switch valve are also controlled by control system.
Further improvement of the utility model is: control system is SIS interlock system.
Compared with the prior art, the utility model has the following advantages: high temperature or rupture pressure disc explosion occur in oxidator
When, nitrogen is timely supplemented into oxidator top, moment starvation, so that reaction moment stops, flammable explosive gas
Moment is diluted, and achievees the purpose that security protection.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model；
Figure label: 1- oxidator；2- temperature sensor；3- rupture disk；4- detonating signal sensor；5- control
System；6- nitrogen buffer tank；7- remote control switch valve.
Specific embodiment:
It, below will be to the utility model to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Technical solution in embodiment is clearly and completely described, it is clear that described embodiment is that the utility model a part is real
Example is applied, instead of all the embodiments.The elements and features described in a kind of embodiment of the utility model can be with one
Elements and features shown in a or more other embodiment combine.It should be noted that for purposes of clarity, in explanation
The expression and description of component unrelated with the utility model, known to persons of ordinary skill in the art and processing is omitted.It is based on
The embodiments of the present invention, those of ordinary skill in the art institute obtained under the premise of not making the creative labor
There are other embodiments, fall within the protection scope of the utility model.
A kind of a kind of embodiment of silver-colored formaldehyde safety device of the utility model as shown in figure 1, including oxidation
Device 1, oxidator 1 are equipped with temperature sensor 2 and rupture disk 3, and rupture disk 3 is connected with detonating signal sensor 4, temperature sensor
2 and detonating signal sensor 4 controlled by control system 5, protective device further includes nitrogen buffer tank 6, and nitrogen buffer tank 6 is connected with
Remote control switch valve 7, remote control switch valve 7 are also controlled by control system 5, and control system 5 is SIS interlock system.
The function of nitrogen buffer tank is to ensure that in the short time that nitrogen enters in reactor the effect for forming effective oxygen isolation；
The function of remote control switch valve is filled with by the nitrogen of control system control in emergency circumstances；Detonating signal sensor and temperature
Degree sensor function is that high temperature or the pressure sharply raised state of emergency occur for monitoring reactor.
The effect of the utility model is when high temperature occurs for device or explosion rupture disk bursts, and temperature sensor or explosion rupture disk pass
Sensor issues a signal to SIS interlock system, and SIS interlock system indicates that remote control switch valve opens valve, and nitrogen is from surge tank
It is injected into oxidator rapidly, covers the bed of entire oxidator, reach the function of moment fire extinguishing, it is different to greatly reduce reaction
Bring risk when often.
When the detonating signal sensor of temperature sensor in oxidator and explosion rupture disk sends out an emergency signal, control system is vertical
Pneumatic on-off valve is opened, nitrogen was covered entire catalysts high temperature bed, effective starvation in the short time.Silver-colored method
, can be effectively by dangerous item station in inside reactor when generating high temperature or explosion rupture disk explosion in oxidation of formaldehyde device, it will not be to whole
A process units or personnel bring secondary hazards, are the effective control measure of one kind of oxidation technology harm.
Detection, instruction, the movement of Formaldehyde Production overall process involved in the utility model are entirely to automatically control, and scene is not
Personnel are needed, the risk of personal injury when reducing emergency measure processing, emergency processing is timely, and treatment effect is preferable, prevents disaster
Extension.
Finally, it should be noted that although the utility model and its advantage have been described in detail above it should be appreciated that
Various change can be carried out without departing from the spirit and scope of the utility model being defined by the claims appended hereto
Become, substitute and converts.Moreover, the scope of the utility model is not limited only to process, equipment described in specification, means, method
With the specific embodiment of step.One of ordinary skilled in the art is from the disclosure of the utility model it will be readily understood that root
It can be used according to the utility model and execute the function of communicating substantially to corresponding embodiment described herein or obtain basic with it
The result communicated, existing and to be developed in the future process, equipment, means, method or step.Therefore, appended right
It is required that be intended to includes such process, equipment, means, method or step in the range of them.
