Description
technical field:
The utility model belongs to smelting equipment field, is specifically related to a kind ofly in STEELMAKING PRODUCTION, press oxygen safe storage transporting system.
background technique:
Before oxygen channel and oxygen spherical tank are installed, overhaul or are come into operation after Long-time Shut-down again, should by the moisture, iron filings, foreign material etc. that remain in pipeline with purging clean, till without iron rust, dust and other foreign material without oil drying air or nitrogen.The gas velocity purged should be not less than 20m/s, and is not less than the design current velocity of oxygen channel, and forbids to use oxygen blow pipeline.
Current all oxygen pipe networks, oxygen spherical tank purge and replace the nitrogen used is all low-pressure nitrogen, and pressure is 0.7 ~ 0.8MPa, and the pressure rating of medium pressure nitrogen, middle pressure oxygen is 2.0MPa.When the oxygen channel that comes into operation, oxygen spherical tank, according to working specification regulation, oxygen ductwork pressure must be reduced to 1.0MPa, and the draught head of guarantee oxygen main valve both sides is less than 0.3MPa; And oxygen pressure is too low will cause tremendous influence to STEELMAKING PRODUCTION, cause some production line even may stop, stop production.
From oxygen compressor emptying, ductwork pressure reduces, come into operation pipeline or spherical tank, until oxygen pipe network pressure recover, this process at least needs 3 hours.Each reduction oxygen ductwork pressure, oxygen compressor all needs to diffuse in a large number, also causes the waste that product is huge.
model utility content:
The purpose of this utility model is to solve the problem, thus presses oxygen safe storage transporting system in the one proposed.
The technical solution adopted in the utility model is: press oxygen safe storage transporting system in one, comprise 400m
3low-pressure nitrogen spherical tank, low pressure nitrogen press, low-pressure nitrogen pipe network, 400m
3middle pressure oxygen spherical tank, middle pressure oxygen compressor and middle pressure oxygen pipe network, low-pressure nitrogen pipe network is provided with blow down valve DN150, nitrogen valve and nitrogen atmospheric valve DN50, middle pressure oxygen hose is provided with oxygen main valve on the net, it is characterized in that: described low-pressure nitrogen pipe network is set up new medium pressure nitrogen gas pipe network and connect the medium pressure nitrogen balloon tank and medium pressure nitrogen press newly established; Described low-pressure nitrogen pipe network, medium pressure nitrogen gas pipe network are all connected with user side with middle pressure oxygen pipe network.
Further, described medium pressure nitrogen gas pipe network is provided with medium pressure nitrogen gas blow down valve DN100A, medium pressure nitrogen gas blow down valve DN100B and nitrogen atmospheric valve DN80.
Further, described medium pressure nitrogen gas pipe network is provided with pressure meter.
Further, described medium pressure nitrogen balloon tankage size is 400m
3.
The beneficial effect that the utility model produces is:
1
,the utility model structure is simple, easily manufactured, can be prefabricated in advance, field joint.
2, after the utility model adopts, oxygen channel, the oxygen spherical tank process of coming into operation need not reduce oxygen ductwork pressure, eliminate the impact on producing.
3, after the utility model adopts, avoid oxygen channel, the oxygen spherical tank process oxygen compressor that comes into operation must diffuse the waste caused.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, in one, press oxygen safe storage transporting system, comprise the 400m on original low-pressure nitrogen pipe network 5
3low-pressure nitrogen spherical tank 1 and low pressure nitrogen press 2, the 400m on middle pressure oxygen pipe network 6
3middle pressure oxygen spherical tank 3 and middle pressure oxygen compressor 4, low-pressure nitrogen pipe network 5 is provided with blow down valve DN150, nitrogen valve 8 and nitrogen atmospheric valve DN50, and middle pressure oxygen pipe network 6 is provided with oxygen main valve 7, and low-pressure nitrogen pipe network 5 is connected to 400m
3between middle pressure oxygen spherical tank 3 and oxygen main valve 7.
The nitrogen used in original oxygen pipe network, oxygen spherical tank purging and displacement is all low-pressure nitrogen, and pressure is 0.7 ~ 0.8MPa, and the pressure rating of medium pressure nitrogen, middle pressure oxygen is 2.0MPa.When the oxygen channel that comes into operation, oxygen spherical tank, according to working specification regulation, oxygen ductwork pressure must be reduced to 1.0MPa, and the draught head of guarantee oxygen main valve both sides is less than 0.3MPa; And oxygen pressure is too low will cause tremendous influence to STEELMAKING PRODUCTION, cause some production line even may stop, stop production.
Therefore on existing pipe network, newly established a medium pressure nitrogen gas pipe network 11 is connected on low-pressure nitrogen pipe network 5, and medium pressure nitrogen gas pipe network 11 is provided with 400m
3medium pressure nitrogen balloon tank 9 and medium pressure nitrogen press 10, be also provided with medium pressure nitrogen gas blow down valve DN100A, medium pressure nitrogen gas blow down valve DN100B and nitrogen atmospheric valve DN80.All be connected with user side 12 with middle pressure oxygen pipe network 6 at low-pressure nitrogen pipe network 5, medium pressure nitrogen gas pipe network 11.Wherein when purging pipe network, using the medium pressure nitrogen gas of 2.0MPa as source of the gas, making oxygen channel, oxygen spherical tank need not reduce oxygen ductwork pressure in the process of coming into operation, eliminating the impact on producing.Also be provided with pressure meter in the joint of the medium pressure nitrogen gas pipe network 11 newly established and low-pressure nitrogen pipe network 5, the nitrogen pressure in medium pressure nitrogen gas pipe network 11 can be monitored at any time.
After new medium pressure nitrogen gas pipe network 11 comes into operation, effectively avoid oxygen channel and oxygen spherical tank must diffuse the waste caused at the process oxygen compressor of coming into operation, and the utility model structure being simple, easily manufactured, eliminating the impact on producing.
Shown in the above and figure is only preferred implementation of the present utility model.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
