Abstract
The invention relates to a gas conveying pipeline for the methyl aldehyde production process. The gas conveying pipeline comprises a plurality of conveying pipes which are connected in a sealed mode through flange plates and bolts. Each conveying pipe comprises an inner pipe body and an outer pipe body, wherein an annular cavity is formed between the outer pipe body and the inner pipe body. A gas pressure detection sensor is arranged in each cavity and connected with a controller through a data line. The controller is connected with an alarming device. The conveying pipes are connected in the sealed mode through the flange plates and the bolts, each conveying pipe comprises the inner pipe body and the outer pipe body, annular cavities are formed between the outer pipe bodies and the inner pipe bodies, each cavity is internally provided with the corresponding gas pressure detection sensor, the gas pressure detection sensors are connected with the controller through the data lines, and the controller is connected with the alarming device; gas leakage can be effectively avoided, and when gas leaks, the gas pressure detection sensors are used for detection, and alarming is carried out.
Description
Technical field
The invention belongs to Formaldehyde Production technical field, be specifically related to the gas of a kind of formaldehyde production
Body conveyance conduit.
Background technology
Formaldehyde is a kind of important basic organic chemical industry raw material, is widely used in chemical industry.
In this year, the annual formaldehyde yield of China is more than ten million ton.In the prior art, the most frequently used side
Method uses silver method methanol oxidation will to be utilized to be produced as formaldehyde.Can use during in Formaldehyde Production
Very gas transmission pipeline, in gas course of conveying, if pipeline once ruptures, not only can
Make the gas moment carried reveal, but also influence whether that produce is smoothed out, carry out
Affect the quality of product, and owing to pipeline is longer, more complicated, which detects by manual type
Pipeline generation leakage there be difficulties involved when, therefore, it is necessary to a kind of safe transport pipeline of exploitation.
Summary of the invention
It is an object of the invention to solve above-mentioned technical problem and provide a kind of formaldehyde production to use
Gas transmission pipeline.
For achieving the above object, the present invention is by the following technical solutions:
The gas transmission pipeline of a kind of formaldehyde production, manages including many conveyings, described many
Conveying pipe is connected by ring flange and bolt seal, and every conveying pipe includes inner tube and outer tube,
There is between described outer tube and said inner tube toroidal cavity, in described cavity, be provided with a gas pressure inspection
Surveying sensor, described gas pressure detection sensor connects controller, described control by data wire
Device connects an alarm.
Described controller and described alarm are provided with on the outer wall of described conveying pipe.
Described data wire is drawn in described ring flange.
The present invention is connected by ring flange and bolt seal by many conveying pipes, every conveying pipe
Including inner tube and outer tube, there is toroidal cavity, in described cavity between described outer tube and said inner tube
Being provided with a gas pressure detection sensor, described gas pressure detection sensor is by data wire even
Connecing controller, described controller connects an alarm, not only can effectively prevent gas leakage,
And can be detected by gas pressure detection sensor when gas leakage, and by report
Alert device is reported to the police, it is achieved thereby that the safety of gas conveying.
Accompanying drawing explanation
Fig. 1 show the gas conveying of a kind of formaldehyde production that the embodiment of the present invention provides
The structural representation of pipeline.
Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features and the advantage of the present invention are further described, but
The invention is not limited in listed embodiment.
Referring to Fig. 1, the gas transmission pipeline of a kind of formaldehyde production, including many conveyings
Pipe 1,2,3, described many conveying pipes are tightly connected by ring flange 4 and bolt 5, every
Conveying pipe includes inner tube 6 and outer tube 7, has toroidal cavity 8 between described outer tube and said inner tube,
A gas pressure detection sensor 9, described gas pressure detection sensor it is provided with in described cavity
Connecting controller 11 by data wire 10, described controller connects an alarm 12.
It should be noted that by the setting of inner and outer pipe, in gas course of conveying by inner tube
When occurring to reveal, produce and serve protective action, gas will not be made directly to reveal in air, will not
Have influence on the carrying out of production, also will not contaminated air, it addition, by be provided with gas pressure detection pass
Sensor, in toroidal cavity, can find to reveal the pipeline of gas by detection, in order to corresponding immediately
Production process when completing, immediately take measures, close source of the gas, change and reveal pipeline, it is ensured that be raw
That produces is smoothed out.
Preferably, described controller and described alarm are provided with on the outer wall of described conveying pipe.
Preferably, described data wire is drawn in described ring flange, and described data wire leads to through hole
Cross epoxide-resin glue to seal, prevent the gas after revealing from running out of, affect Detection results.
The present invention is connected by ring flange and bolt seal by many conveying pipes, every conveying pipe
Including inner tube and outer tube, there is toroidal cavity, in described cavity between described outer tube and said inner tube
Being provided with a gas pressure detection sensor, described gas pressure detection sensor is by data wire even
Connecing controller, described controller connects an alarm, not only can effectively prevent gas leakage,
And can be detected by gas pressure detection sensor when gas leakage, and by report
Alert device is reported to the police, it is achieved thereby that the safety of gas conveying.
The above is only the preferred embodiment of the present invention, it is noted that for the art
Those of ordinary skill for, under the premise without departing from the principles of the invention, it is also possible to make some
Improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
