Technical field
The invention belongs to flammable gas pipeline safety displacement fields, and in particular to carry out nitrogen when to a kind of pipeline maintenance and set
The small-scale liquid nitrogen gasification installation changed.
Background technique
Inflammable gas pipeline need to carry out nitrogen displacement to medium in pipe, it is great to avoid fire explosion etc. in maintenance
Accident.There are mainly two types of for the currently available typical nitrogen device for replacing operation on site:
First is that being carried out using bottled nitrogen for nitrogen, such as application No. is 201720963144.6 Chinese patents to provide one kind
The equipment for carrying out nitrogen displacement inside pipeline using bottled nitrogen, has conveniently moving, and feature easy to operate is, it can be achieved that continuous
It steadily supplies, but is only applicable to the lesser operating condition of gas consumption, while the higher pressure store of nitrogen cylinder, also it is transported and is made
With proposing higher requirement.
Second is that being carried out using liquid nitrogen gasification for nitrogen, such as application No. is 201710637459.6 Chinese patents to provide one kind
Blowing pipeline liquid nitrogen gasification device has compact-sized, multiple functional feature, can meet in non-transformer, purges
The big dosage requirement of nitrogen.But the auxiliary device in the device is more, keeps its bulky, is unfavorable for the fortune in remote districts
It is defeated.
Summary of the invention
Object of the present invention is to: be to provide it is a kind of compact and flexible, it is easy to operate, be suitable for the displacement of field short distance pipeline and make
The liquid nitrogen gasification device of industry.
The technical solution adopted by the present invention is as follows:
A kind of pipeline displacement small-scale liquid nitrogen gasification installation, including frame, from pressurization liquid nitrogen container, air-heating type gasifier, remittance
Stream row and cryogenic hose, it is characterised in that: the frame is divided into upper layer and lower layer, described to be located at frame bottom from pressurization liquid nitrogen container,
The air-heating type gasifier is located at frame top layer, the busbar connector and cryogenic hose for connecting two from pressurization liquid nitrogen container and sky
Heating type gasifier.
Further, saddle is welded in the supporting beam of the frame bottom, it is described to be placed side by side on saddle from pressurization liquid nitrogen container
On seat, fixed by banding.
Further, the busbar connector passes through cryogenic hose and connects two from pressurization liquid nitrogen container, and connects branch road and be also equipped with
Cryogenic globe valve, user, which can according to need, to be used alternatingly or feed flow simultaneously；The busbar connector is drawn from union tee, with
The air inlet pipe of air-heating type gasifier is connected.
Further, the air-heating type gasifier uses 4 × 4 square layout, is fixed on frame by bolt support
Top；Nitrogen stream meter is installed, outlet end is standard flange interface on the exhaust pipe of the air-heating type gasifier；The nitrogen
Flowmeter uses lithium battery power supply, facilitates field work environment.
The beneficial effects of the present invention are: the present apparatus is integrated by liquid nitrogen container and air-heating type gasifier using frame, empty
Between it is rationally distributed, compact；Liquid nitrogen is supplied using from supercharging mode, simplifies device；Using busbar connector and two liquid nitrogen containers are connect, are protected
The stabilization sustainable supply of liquid nitrogen is demonstrate,proved；All valves, interface are respectively positioned on device one end, convenient for operation；The device is compact and flexible, behaviour
Facilitate, meets vehicle-mounted transport requirement, the displacement operation suitable for field short distance pipeline.
