Abstract
The invention provides a micro-positive pressure explosion-proof offshore container which comprises a container body, a closed external door, an explosion-proof blower, an air inlet and an air outlet, wherein the air inlet is formed at the corner on one side of the box wall of the container body, the air outlet is formed at the corner of the box wall on one side of the diagonal line of the air inlet, the explosion-proof blower is mounted at the air inlet, and the closed external door is arranged on the box wall on one side of the air inlet. The explosion-proof blower mounted at the air inlet can input clean air into a main room constantly, and the clean air is input from the air inlet and output from the air outlet. The blast gate at the air inlet and the blast gate at the air outlet are manually adjusted, and air mass flow variation caused by air mass flow adjustment can be monitored through an air mass flow detector, so as to keep the pressure of protective gas inside the container to be +70Pa and enable the non-explosion-proof general electrical equipment inside the container to be used normally.
Description
Technical field
The present invention relates to a kind of offshore container using on oil exploitation platform, relate in particular to a kind of explosion-proof offshore container of pressure-fired using in hydrogen class explosive gas atmosphere.
Background technology
Offshore container has been widely used in the goods and materials storage of off-shore oil rig operation, the fields such as transportation, and offshore container carries out interior transformation and installs institution additional also can becoming offshore platform personnel's rest room, office, lodging room, operation function cabin etc.But the offshore oil operation electric installation using in may there is explosive gas atmosphere must meet requirement of explosion proof, and the cost of explosion-proof electrification device is very high, general common electric utility cannot reach requirement of explosion proof simultaneously, such as display, printer, Deng, existing offshore container does not possess corresponding explosion-proof performance yet.
Summary of the invention
For the defect existing in prior art and deficiency, the object of this invention is to provide the explosion-proof offshore container of a kind of pressure-fired, under the prerequisite of having controlled well cost, greatly strengthened the explosion-proof performance of offshore container.
For achieving the above object, the present invention adopts following technical scheme:
The explosion-proof offshore container of a kind of pressure-fired, comprise container body, airtight external door, explosion-proof fan, air intake, air outlet, described container body tank wall one side corner has air intake, the tank wall corner of air intake diagonal one side has air outlet, described explosion-proof fan is arranged on air intake place, on air intake one side box wall, offers airtight external door.
Further, container body is divided into main room and Liang Ge region, gas lock district.
Further, gas lock district is arranged between airtight external door and main room, on the opposite side gas lock district bulkhead of described airtight external door, offers inside door.
Further, air intake place is provided with gas concentration probe and air mass flow probe.
Further, air intake and air outlet place are equipped with air lock and fire resisting damper.
Further, the explosion-proof fan at air intake place adopts 112G explosion-proof centrifugal breeze fan.
Advantage of the present invention and beneficial effect are:
1. the explosion-proof offshore container of pressure-fired of the present invention has the usage space that light is put in oil platform and hydrogen class explosive gas atmosphere, can guarantee production and operating personnel's safety.
2. user can configure according to the demand of self own equipment in case, and the explosion-proof performance of equipment is no longer included to requirement, and general equipment can be used in this case, has reduced cost.
3. case inner region can freely be divided, and forms rest room, Office Area and the operation area etc. of several functions.

The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 4, on offshore container 1 right side casing, offer airtight external door 2 and air intake 14, air intake 14 places are provided with air lock 7, the air mass flow that air lock 7 can regulate air intake with holding chamber internal pressure for for example+70Pa.At air intake, 14 places are also provided with explosion-proof fan 6, and this blower fan can adopt for example 112G explosion-proof centrifugal breeze fan.Air intake 14 places, air channel are provided with fire resisting damper 9 to meet fire protection requirement.The air outlet place of explosion-proof fan 6 is provided with for detection of the gas concentration probe 8 of fiery gas bulk concentration and for monitoring the air mass flow probe 10 of the air mass flow that enters offshore container 1.
The interior zone of offshore container 1 is divided into main room 5 and gas lock district 3, between main room 5 and gas lock district 3, has inside door 4 to separate, and by airtight external door 2, can have outside to enter gas lock district 3.Gas lock district 3 transition region for entering main room 5, airtight external door 2 and inside door 4 be arranged so that opening sealing external door 2 enters gas lock district 3 time protection pressure in main room 5 can not be reduced to zero.
On air intake 14 oppose side walls of offshore container 1, offer air outlet 11, be provided with air lock 13 for adjusting air quantity in air outlet 11, place, the air channel of air outlet 11 is provided with fire resisting damper 12 equally to meet fire protection requirement.
The explosion-proof offshore container of this pressure-fired in use can by explosion-proof fan 6 continual by air intake 14 and air lock 7 to the interior input pure air in main room 5, take and keep protective gas pressure in container as+70Pa.Pure air is inputted by air intake 14, from air outlet 11 outputs.Gas concentration probe 8 can detect the fiery gas bulk concentration in main room; and the take this as a foundation next air lock 7 of artificial manual adjustments air intake 14 and the air lock 13 of air outlet 11; regulate the air mass flow that air mass flow causes to change and can monitor by air mass flow probe 10, so that it meets the positive pressure protection requirement that General Electric's equipment is used.
When operating personnel enters offshore container 1, first by sealing external door 2, enter gas lock district 3, close sealing and open again inside door 4 after external door 2, to guarantee to make the air pressure in main room 5 be reduced to zero, guarantee the use safety of the explosion-proof offshore container of this pressure-fired.
The foregoing is only preferred embodiment of the present invention, be not used for limiting practical range of the present invention; If do not depart from the spirit and scope of the present invention, the present invention is modified or is equal to replacement, all should be encompassed in the middle of the protection domain of the claims in the present invention.
