Abstract
A method for simultaneously testing gas tightness of a gas purification tower and gas pipelines is characterized by the following steps a, finishing installing of the gas purification tower and a connected gas pipeline system according to a conventional installation method and enabling the gas purification tower and the connected gas pipelines to be communicated; b, providing a peripheral air compressor to supply air to the gas purification tower and the connected gas pipeline system; c, enabling pressure inside the gas purification tower and the connected gas pipeline system to be maintained in 0.045 MPa and stabilizing for 2 hours; spraying soap water on bonding surfaces of welding seams and flanges inside the gas purification tower and the connected gas pipeline system and finally judging the gas tightness test to be qualified if no obvious bubbles exist. The method for simultaneously testing gas tightness of the gas purification tower and the gas pipelines has the advantages of being simple in test measures, short in practical and testing time, rapid in efficiency and low in cost.
Description
Technical field
The present invention relates to a kind of airtightness testing method, specifically, is that a kind of gas purification tower and gas piping carry out airtightness testing method simultaneously.
Background technology
At present domestic built or building in gas purification engineering, the air-tight test of gas purification tower and gas piping is generally to test separately respectively, conventional way is by all gas purification towers and the blind plate shutoff of gas piping interface, blow in apparatus system by peripheral hardware air compressor machine, with system within a certain period of time pressure drop can be controlled at certain limit and judge that whether air-tight test qualified.But because gas purification tower is larger, coupled gas piping is generally also larger, after gas purification tower tower body air-tight test completes, gas piping is installed, and the gas piping air-tight test of will carrying out being connected with tower, must be between gas piping and gas purification tower flange-interface blank off, after to be tested completing, blind plate is removed, in the process of removing, just there will be the packing less problem of interface possibility, the gas piping flange-interface appearance leakage that can cause tower and be connected.
Therefore the method that known gas purification tower and gas piping carry out separately respectively air-tight test exists above-mentioned all inconvenience and problem.
Summary of the invention
Object of the present invention, is that the gas purification tower and the gas piping that propose the interior all weld seams of a kind of stifled exhausted apparatus system and flange connections leakage carry out airtightness testing method simultaneously.
For achieving the above object, technical solution of the present invention is:
A kind of gas purification tower and gas piping carry out airtightness testing method simultaneously, it is characterized in that comprising the following steps:
A, according to conventional installation method, gas purification tower is all installed with the gas piping system that is connected, gas purification tower and the gas piping that is connected are communicated with;
B, provide peripheral hardware air compressor machine to gas purification tower and the gas piping system air-supply of being connected;
C, make gas purification tower maintain 0.045MPa pressure with in the gas piping system that is connected, voltage stabilizing two hours;
D, to gas purification tower and all weld seams in the gas piping system that is connected and flange faying face spraying suds, finally not have obvious bubble to judge that air-tight test is qualified.
Gas purification tower of the present invention and gas piping carry out airtightness testing method simultaneously and can also be further achieved by the following technical measures.
Aforesaid method, wherein said gas purification tower is installed blind plate and gate valve with the gas piping system inlet and outlet that is connected.
Aforesaid method, wherein said gas purification top of tower and bottom be setting pressure table respectively.
Adopt after technique scheme, gas purification tower of the present invention and gas piping carry out airtightness testing method simultaneously and have the following advantages:
1, test measure is simple, practical;
2, test period is short, effect is fast, cost is low;
3, field conduct effect is fine, is convenient to promote in gas purification engineering construction field.
Accompanying drawing explanation
Fig. 1 is the device air-tight test schematic diagram of the embodiment of the present invention.
In figure: 1 gas purification tower, 2 first tensimeters, 3 second tensimeters, 4 gate valves, 5 blind plates.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof, the present invention is illustrated further.
Now refer to Fig. 1, the device air-tight test schematic diagram that Fig. 1 is the embodiment of the present invention.
Gas purification tower of the present invention and gas piping carry out airtightness testing method simultaneously, it is characterized in that comprising the following steps:
A, according to conventional installation method, gas purification tower is all installed with the gas piping system that is connected, gas purification tower and the gas piping that is connected are communicated with; Described gas purification tower is installed blind plate and gate valve with the gas piping system inlet and outlet that is connected, and described gas purification top of tower and bottom be setting pressure table respectively.
B, provide peripheral hardware air compressor machine to gas purification tower and the gas piping system air-supply of being connected;
C, make gas purification tower maintain 0.045MPa pressure with in the gas piping system that is connected, voltage stabilizing two hours;
D, to gas purification tower and all weld seams in the gas piping system that is connected and flange faying face spraying suds, finally not have obvious bubble to judge that air-tight test is qualified.
It is to blow in system by the air compressor machine of peripheral hardware that gas purification tower of the present invention and gas piping carry out airtightness testing method simultaneously, make to maintain in system certain pressure, then whether all weld seams of check system and flange connections leak, thereby reach the object of air-tight test.It is simple, practical that gas purification tower of the present invention and gas piping carry out airtightness testing method test measure simultaneously, and test period is short, effect is fast, cost is low.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
