Description
Technical field
This utility model relates to the technical field of liquid level measurement of chemical production equipment, relates in particular to a kind of gas analysis
Supplementary structure measured by instrument.
Background technology
Along with factory automation degree is more and more higher, the procedure parameter of system is particularly important, then just require package unit
Links is all possessed real-time power of test.Wherein gas analysis instrument belongs to one of common meter type, it is possible to the most anti-
Reflect the change that the gas medium in pipeline occurs in process of production, and certain gas content can be accurately provided.
In most of process of factory production, the temperature of gas in pipelines is the highest, and sampling pipe is soaked by existing technology
In recirculated water, recirculated water is flowing, has taken away gas in pipelines major part heat.The method is relatively conventional, it is possible to possess
The function of cooling, but the method needs to avoid gas in pipelines can not contact with recirculated water, improves and seals grade, it is impossible to has leakage
Point, otherwise gas will contact water, particularly special gas, and vigorous reaction, such as titanium tetrachloride gases, chlorine can occur after contact
Deng, if gas flows into analysis meter after Fan Ying, damage will be directly contributed.But prove under actual condition, after long-term use,
Aging along with gas attack and pipeline, accomplishes that it is relatively difficult for sealing impermeable completely.If this problem cannot solve, that
Gas analysis instrument exists for potential safety hazard, therefore need to find out suitable way as early as possible, to improve security of system.
Utility model content
The purpose of this utility model is the defect for above-mentioned prior art, it is provided that auxiliary knot measured by a kind of gas analyser
Structure, prevents gas from leaking, and improves security of system.
To achieve these goals, the technical solution of the utility model is:
Supplementary structure measured by a kind of gas analyser, including gas pipeline and the gas analysis being arranged on gas pipeline
Instrument, increases between described gas pipeline and gas analyser and arranges sampling pipe, and described sampling pipe is double-skin duct, including one
The exocoel as cooling duct that the individual inner chamber as sampling passage and ring are located at outside inner chamber, described gas splitter passes through conduct
The inner chamber of sampling passage is connected with gas pipeline, and described exocoel one end is provided with nitrogen cooling tube, and the other end is provided with nitrogen
Effuser, described nitrogen cooling tube accesses nitrogen pot.
As the improvement to technique scheme, described nitrogen cooling tube is arranged on the upper end of exocoel, and described nitrogen flows out
Pipe is arranged on the lower end of exocoel.
As the improvement to technique scheme, the pressure in described nitrogen cooling tube is more than the pressure sampling air-flow in inner chamber
Power.
Compared with prior art, the beneficial effects of the utility model are:
Supplementary structure measured by gas analyser of the present utility model, before analysis meter, increases a set of nitrogen cooling dress
Put.So, the flow direction of nitrogen is contrary with the gas flow direction of sampling passage, takes away amount of heat.Nitrogen pressure requirement
Higher than sample gas pressure, and big flow persistently provides.Even if the method ensure that interior conduit has faint leakage, nitrogen also can prevent
Sample gas overflows, and does not haves production accident；More additionally, if there being leakage phenomenon, nitrogen can enter sample gas by leakage point, and
Judged whether to reveal by the sudden change of analysis meter numerical value.
Present design increases nitrogen cooling device, can not only reduce the temperature of sample gas in pipeline and rotten to instrument
Erosion, even and if under leak case, nitrogen can prevent sample gas from overflowing, harm will not be produced, and analysis meter numerical value can be passed through
Change judge whether reveal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is further described.
As it is shown in figure 1, supplementary structure measured by gas analyser of the present utility model, including gas pipeline 1 be arranged on gas
Gas analyser 2 on body pipeline 1, between described gas pipeline 1 and gas analyser 2 increase sampling pipe 3 is set, described in take
Sample pipeline 3 is double-skin duct, including one as the sampling inner chamber 4 of passage and ring be located at outside inner chamber 4 as cooling duct
Exocoel 5, described gas splitter 2 is connected with gas pipeline 1 by the inner chamber 4 as sampling pipe, and described exocoel 5 one end sets
Being equipped with nitrogen cooling tube 6, the other end is provided with nitrogen effuser 7, and described nitrogen cooling tube 6 accesses nitrogen pot.
Described nitrogen cooling tube 6 is arranged on the upper end of exocoel 5, and described nitrogen effuser 7 is arranged on the lower end of exocoel 5.
Pressure in described nitrogen cooling tube 6 is more than the pressure sampling air-flow in inner chamber 4.
Compared with prior art, the beneficial effects of the utility model are:
Supplementary structure measured by gas analyser of the present utility model, before analysis meter, increases a set of nitrogen cooling dress
Put.So, the flow direction of nitrogen is contrary with the gas flow direction of sampling passage, takes away amount of heat.Nitrogen pressure requirement
Higher than sample gas pressure, and big flow persistently provides.Even if the method ensure that interior conduit has faint leakage, nitrogen also can prevent
Sample gas overflows, and does not haves production accident；More additionally, if there being leakage phenomenon, nitrogen can enter sample gas by leakage point, and
Judged whether to reveal by the sudden change of analysis meter numerical value.
Present design increases nitrogen cooling device, can not only reduce the temperature of sample gas in pipeline and rotten to instrument
Erosion, even and if under leak case, nitrogen can prevent sample gas from overflowing, harm will not be produced, and analysis meter numerical value can be passed through
Change judge whether reveal.
The above is only a kind of embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement, these improve also should
It is considered as protection domain of the present utility model.
