Description

The special-purpose inert gas generator of packaged type

Technical field

The utility model belongs to the petroleum industry apparatus field, specially refers to a kind of portable inert gas generator that cleans large oil tank that is exclusively used in.

Background technology

Along with the needs of oil industry development, the supporting all kinds of petroleum storage tanks of building also at emerge in multitude constantly, at present, the countries in the world oil play is attached great importance to the cleaning of storage tank.Because the storage tank bottom is through a large amount of settling of long-term oil storage meeting deposition, as pitch, cured, silt etc., wherein 98% is available composition, the standing storage meeting causes unfavorable phenomenons such as the corrosion of storage tank and the wasting of resources, here need storage tank is carried out regular maintenance, before carrying out maintenance and inspection, just must be to cleaning completely in the jar, the cleaning of oil tank, be again the work that safety coefficient is less, reason is the jar end in the storage tank, tank skin all has a large amount of oil, in the cleaning process, can produce a large amount of oil gas, be easy to generation of static electricity spark, unsafe factors such as explosion caused accident, the generation that wants to stop this type of accident because of producing in the cleaning, will reduce the oxygen content in the oil tank, generally should be controlled to be below 8%, way in the past all is toward a jar interior nitrogen injection, but is to use nitrogen that many unfavorable factors are arranged: 1, the cost height; 2, in nitrogen supply (NS) inconvenience from far-off regions; 3, the usage quantity of nitrogen is big, and utilization ratio is low; When 4, container sealing was not tight, nitrogen volatilized easily in jar; 5, the temperature in nitrogen can make jar reduces, and is unfavorable etc. to the cleaning of oil tank.Because above many unfavorable factors, the design people's collection practical work experience for many years, research and design, pilot development goes out the inert gas generator of this portable special use that can effectively utilize, in the cleaning of oil tank, when the needs rare gas element can pass through this device delivery pipeline, " manhole " or shell manhole place through tank deck are injected in the oil tank continuously, reduce a jar interior oxygen composition, reach safety standards, simultaneously, this device is when producing rare gas element, produce high-temperature vapour high-temperature vapour is injected into water tank, water is heated, be used further to clean, help oil tank is thoroughly cleaned.

Summary of the invention

The utility model technical issues that need to address are, in prior art, clean the canned liquid nitrogen of the inner employing of large-scale oil storage tank, the cost height, transport inconvenience, many weak points such as effective rate of utilization difference, in order to overcome these deficiencies, and design the special-purpose inert gas generator of a kind of packaged type, its cost is only for cleaning 1/30 of the required nitrogen cost of same volume oil tank, and it is convenient and safe, the purpose of this utility model, rely on and realize with following technical proposals, the special-purpose inert gas generator of a kind of packaged type, comprise the pipeline of a conveying rare gas element that links to each other with device and reach port, it is characterized in that, this device totally is to be fixedly mounted in the removable storehouse, and the source that produces gas in the device is to rely on industrial boiler, with the fuel system of boiler auxiliary work---tanks, suction pump; Soft water system---automatic water softener, salt cellar, water softening tank; The boiler sidepiece is provided with coupled blower fan, and boiler export is through cooling system---cooling water tank, driving pump, chilling spray; Link to each other with the pipeline of carrying rare gas element, again through one can gas-water separation container, and be connected in the storage tank by gaseous constituent and concentration detector.Described mobile storehouse, its four scroll wheel of packing on can the base plate with whole bin also can vehicle-mounted whole bin, leaves for the location of storage tank.The pipeline of described conveying rare gas element injects in the jar from oil tank top " manhole " or shell manhole.

The beneficial effects of the utility model are, what send out in the device is the special-purpose rare gas element of the extremely low high temperature of oxygen level, simultaneously, be attended by the conveying of high hot water and steam, utmost point advantageous conditions is provided cleaning the storage, and rare gas element can use at any time at any time and produce, and price is significantly cheap, single unit system can conveniently move, the efficient height of cleaning.

Description of drawings

Fig. 1 is an oil tank synoptic diagram to be cleaned

Fig. 2 is the relation of the link position between the each several part auxiliary facility in this device

Specific implementation method

With reference to Fig. 1, a large amount of sedimental synoptic diagram to be cleaned of expression large-scale oil storage tank accumulation.With reference to Fig. 2, annexation figure in the indication device between each auxiliary facility, the industrial boiler that wherein produces rare gas element is 1, its the place ahead is provided with steering hand wheel and control instruments, cooling apparatus 2 is equipped with on the boiler next door, having that fuel tank 3 is connected with cooling system stands in its other salt cellar 4, it is connecting water softening tank 5, the other blower fan 6 that is provided with of another of boiler, one of boiler brings out mouth and is connected with cooling system, cooling water tank 7, measuring instrument 8 is equipped with at boiler export pipeline place, Shu Chu rare gas element passes the water pot 10 of a filtration usefulness by pipeline 9 thus, directly leads to storage tank 11 to be cleaned again, and the deposition object height is about 1.8 meters.Whole mobile storehouse is 12.
