Description
Technical field
This utility model relates to a kind of leakage testing device, specifically a kind of RONA online leakage testing device of MMT tubular heat exchanger。
Background technology
MMT full name is methyl cyclopentyl-dialkyl-tricarbon manganium, it it is the unleaded gas antidetonator of a kind of excellent performance, its preparation technology is: methyl cycle pentadiene dimer Pintsch process is generated methyl cyclopentadiene, ring sodium still adds oxolane and metallic sodium, methyl cyclopentadiene is dripped in still, after metallic sodium reacts completely, ring sodium hydraulic pressure is entered ring manganese still, add anhydrous Manganese chloride, heat and be obtained by reacting ring manganese liquid, being entered by ring manganese hydraulic pressure heats up and be filled with high pressure carbon monoxide in carbonylation still carries out carbonylation, reacted material enters in distillating still, oxolane in step by step arithmetic material and methyl cyclopentyl-dialkyl-tricarbon manganium (MMT), solid waste is discharged and is focused on, oxolane recycles, MMT purifies further and obtains qualified products。The material that above-mentioned distillation process steams is condensed by tubular heat exchanger, distillates and makes shell side leave with rage, and recirculated water walks tube side, in process of production, owing to heat exchanger tube sheet is washed away by moisture, cavitates and the corrosion of microchemistry medium, often there is seepage in panel weld place, causes that mixing occur in water and material。If water enters oxolane, bring danger can to the reaction of ring sodium。Therefore, need regularly tubular heat exchanger to be carried out leak test。The heat exchanger leak testing process adopted now is tube head of dismantling, cleans tube sheet, is filled with 0.6MPa nitrogen to shell side, and the most backward tube sheet spray suds carry out leak test。There is program complexity, lose time in this leak testing process, and can not the accurate shortcoming such as judgement to pipeline section seepage。
Utility model content
The purpose of this utility model is in that to provide a kind of RONA online leakage testing device of MMT tubular heat exchanger, with the problem solving to propose in above-mentioned background technology。
For achieving the above object, this utility model provides following technical scheme:
A kind of RONA online leakage testing device of MMT tubular heat exchanger, including tubular heat exchanger, shell side imported valve, shell-side outlet valve, tube side imported valve, tube side outlet valve, nitrogen valve, nitrogen pressure table, shell side emptying valve and tube side discharge opeing bottom valve, described shell-side outlet valve, tube side imported valve, tube side discharge opeing bottom valve, shell side imported valve, tube side outlet valve is all connected with tubular heat exchanger with shell side emptying valve, tube side discharge opeing bottom valve and tube side imported valve are in parallel, nitrogen valve, nitrogen pressure table and tube side outlet valve are in parallel, shell side emptying valve is connected with shell side imported valve。
As further program of the utility model: nitrogen valve includes the first nitrogen valve and the second nitrogen valve。
As further program of the utility model: nitrogen pressure epi-position is between the first nitrogen valve and the second nitrogen valve。
Compared with prior art, the beneficial effects of the utility model are: this apparatus structure is simple, reasonable in design, failure rate is low, safety in utilization and good operation stability；Detachability is good, it is simple to installs and changes, simple to operation, can find out whether reading declines intuitively by nitrogen pressure table, thus judging tubular heat exchanger whether seepage accurately, result of use is good；This device saves the time, and work efficiency is high, thus improve economic benefit。
Accompanying drawing explanation
Fig. 1 is the structural representation of the RONA online leakage testing device of MMT tubular heat exchanger。
Wherein: 1-tubular heat exchanger, 2-shell side imported valve, 3-shell-side outlet valve, 4-tube side imported valve, 5-tube side outlet valve, 6-tube side discharge opeing bottom valve, 7-the first nitrogen valve, 8-the second nitrogen valve, 9-nitrogen pressure table, 10-shell side emptying valve。
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail。
Refer to Fig. 1, a kind of RONA online leakage testing device of MMT tubular heat exchanger, including tubular heat exchanger 1, shell side imported valve 2, shell-side outlet valve 3, tube side imported valve 4, tube side outlet valve 5, nitrogen valve, nitrogen pressure table 9, shell side emptying valve 10 and tube side discharge opeing bottom valve 6, described shell-side outlet valve 3, tube side imported valve 4, tube side discharge opeing bottom valve 6, shell side imported valve 2, tube side outlet valve 5 is all connected with tubular heat exchanger 1 with shell side emptying valve 10, tube side discharge opeing bottom valve 6 and tube side imported valve 4 are in parallel, nitrogen valve, nitrogen pressure table 9 and tube side outlet valve 5 are in parallel, shell side emptying valve 10 is connected with shell side imported valve 2。Nitrogen valve includes the first nitrogen valve 7 and the second nitrogen valve 8。Nitrogen pressure table 9 is between the first nitrogen valve 7 and the second nitrogen valve 8。
Operation principle of the present utility model is: when tubular heat exchanger 1 is carried out online leak test, close shell side imported valve 2, shell-side outlet valve 3, tube side imported valve 4 and tube side outlet valve 5, open tube side discharge opeing bottom valve 6, discharge the liquid of tube head and tube side, open shell side emptying valve 10 and make shell side and atmosphere, open the first nitrogen valve 7 and the second nitrogen valve 8, after being filled with 0.6MPa nitrogen to tube head and tube side, close the second nitrogen valve 8, wait for a period of time, observe whether nitrogen pressure table 8 reading declines, as declined, then show that seepage occurs in tubular heat exchanger 1。This apparatus structure is simple, reasonable in design, failure rate is low, safety in utilization and good operation stability；Detachability is good, it is simple to installs and changes, simple to operation, can find out whether reading declines intuitively by nitrogen pressure table 9, thus judging tubular heat exchanger 1 whether seepage accurately, result of use is good；This device saves the time, and work efficiency is high, thus improve economic benefit。
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, it is also possible to make a variety of changes under the premise without departing from this patent objective。
