Abstract
The utility model discloses a thermal-working public housing, including a framework. The framework is sealed and provided with a fire-retardant material coverage. An explosion-proof lighting system is positioned in the thermal-working housing which is ventilated by a pressure system. The pressure system is composed of a mandatory air supply fan, an intake duct, an exhaust duct, an air pressure stable unit. Fresh air is blown into a suction mouth of the inlet duct through the rear of the public housing, whereas waste gas is sent out from the exhaust duct to safe area. The utility model can realize thermal works as welding, incising and polishing etc, under the condition of not shutting down production of circumstances, thereby avoiding huge losses caused by shutdown of production, meanwhile ensuring security of equipment and personnel. The utility model is widely used in oil fields and offshore oil rigs, mines and other industries.
Description
Technical field
Thermal technology's operation room of thermal technology's operations such as the utility model relates to and a kind ofly is used for welding in the explosion-proof area, cuts, polishing.
Background technology
Petrochemical enterprise often need carry out maintenance activity to its device and structure, many times all will relate to thermal technology's operation.
Because thermal technology's excessive risk exists constantly, from security standpoint, when in explosion-proof area, weld, cut, during thermal technology's operation such as polishing, the stopping production of device around often requiring, to guarantee being perfectly safe of thermal technology's operation, this is for a manufacturing enterprise, and especially in today of the high enterprise of oil price, the loss of stopping production obviously is quite huge.Therefore press for provide a kind of and can under not shut-down situation, in explosion-proof area, weld, cut, thermal technology's operation room of thermal technology's operation such as polishing.
The utility model content
Problem to be solved in the utility model provides a kind of when guaranteeing thermal technology's job safety, need not close down thermal technology's operation room that peripheral device is produced.
For achieving the above object, the technical scheme that the utility model adopted is: thermal technology's operation room comprises framework, sealing is coated with fire proofing on the described framework, described thermal technology's operation is provided with the explosion-proof light system within doors, thermal technology's operation room is ventilated by pressure system, described pressure system comprises forced air supply fan, air inlet airduct, exhaust airduct, stable gas pressure unit, by the forced air supply fan at air inlet airduct suction inlet place blast ozone flow through operation behind the house by, waste gas drains into the safety zone from the exhaust airduct.
For to thermal technology's operation within doors/room outside air pressure carry out that differential pressure monitors and control.And the fuel gas at continuous monitoring air inlet port place, operation fuel gas, toxic gas, oxygen content within doors, thermal technology's operation room also comprises automatic control system, described automatic control system comprises oxygen monitoring loop, fuel gas monitoring circuit, control panel unit, alarm signal processing unit, closes down signal processing unit, differential pressure monitoring loop, when in case wherein any index surpasses alarm set value, at once start audible and visible alarm, relevant abnormal conditions are checked in prompting operation staff within doors.If alarm can not get effective control, situation continues variation, when any one index wherein reaches might threaten safe preset value the time, automatic control system can be closed down thermal technology's operation line related (electric welding machine at once, blast fan etc.) and control power supply itself, to guarantee the safety of operation field.
The beneficial effects of the utility model are: the utility model can be implemented under the situation of not closing down peripheral device production, in explosion-proof area, weld, cut, thermal technology's operation such as polishing, avoided the massive losses that manufacturing enterprise caused because of stopping production, guarantee equipment and personal security simultaneously, can be widely used in industries such as oil field, offshore drilling platforms, mine.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model contour structures schematic diagram;
Fig. 2 is an automatic control system circuit block diagram of the present utility model.
The specific embodiment
As shown in Figure 1,1 inside, thermal technology's operation room that is made of fire-retardant parcel cloth parcel framework is provided with explosion-proof light system (because common apparatus, not shown), thermal technology's operation room 1 is ventilated by pressure system, pressure system comprises forced air supply fan and stable gas pressure unit 2, air inlet airduct 3, exhaust airduct 4, blast ozone by the forced air supply fan at air inlet airduct suction inlet place and flow through operation behind the house, waste gas drains into the safety zone from exhaust airduct 4, also is provided with automatic control system 5 on thermal technology's operation room 1.
Fig. 2 is the circuit block diagram of automatic control system 5, comprise the oxygen monitoring loop, the fuel gas monitoring circuit, the control panel unit, the alarm signal processing unit, close down signal processing unit, the differential pressure monitoring loop, as shown in the figure, in the airduct entrance and operation be provided with the combustable gas concentration sensor within doors, be provided with oxygen concentration sensor and differential pressure switch within doors in operation, by the fuel gas display unit, the oxygen display unit, the differential pressure display processing unit transfers signals to the control panel unit and shows current state, when in case wherein any index surpasses alarm set value, at once start audible and visible alarm by the alarm signal processing unit, remind operation within doors the staff check that relevant abnormal conditions handle, if alarm can not get effective control, situation continues variation, when any one index wherein reaches might threaten safe preset value the time, automatic control system can be closed down thermal technology's operation line related (electric welding machine at once by closing down signal processing unit, blast fan etc.) and control power supply itself, to guarantee the safety of operation field, because circuit all adopts universal circuit, no longer provides physical circuit figure at this.
