Technical problem, reduces pressure detecting failure, there is provided a kind of efficient automatic blowing system, can reduce the system failure, it is ensured that pressure
Power detection data accurately, and then improves one-time dedusting effect.
For achieving the above object, the utility model is employed the following technical solutions, High water cut, ash-laden gas pressure detecting dress
Put, it is characterised in that：Pressure on the text of converter one, two literary pipelines takes and install at source point tiltedly wealthy mouth source-taking apparatus, and tiltedly wealthy mouth takes source
Device left end arranges tiltedly wealthy mouth, and tiltedly wealthy mouth is oblique upper left opening, and tiltedly wealthy mouth end insertion flue gas main pipeline about 15cm is in
With flue gas supervisor by being welded to connect；Tiltedly wealthy mouth source-taking apparatus right-hand member is connected by purging ball valve with scavenging pipeline, scavenging pipeline
Upper installation purge solenoid valve, purge solenoid valve Jing scavenging pipelines connection Nitrogen source gases；Tiltedly in the middle part of wealthy mouth source-taking apparatus straight up
Welding takes source capsule road, takes source capsule road and passes sequentially through again and takes source ball valve, the source magnetic valve of taking and be finally coupled to pressure transmitter.
Further, the angle of inclination of the oblique wealthy mouth of described oblique wealthy mouth source-taking apparatus left end is 45 °.
Further, described oblique wealthy mouth source-taking apparatus are to arrange obliquely, horizontal by 20 ° of angles.
The beneficial effects of the utility model are：A text, the two literary inlet and outlet pressure degrees of accuracy are improved, is not only effectively improved
The dust removing effects of primary dedusting system, realize clean manufacturing, and significantly reduce one-time dedusting blower fan and coal gas indirectly
The fault rate of analysis system, improves RECOVERY OF CONVERTER GAS efficiency, is to realize that " negative energy " steel-making contributes；Tiltedly wealthy mouth takes source dress
Putting can effectively prevent from being responsible for arm sewage stream in pressure tappings formation " moisture film ", it is ensured that pressure tappings are normally clear and coherent；Using purge solenoid valve
Carry out nitrogen timing purging control, it is ensured that tiltedly sludge cannot deposit at wealthy mouth, it is ensured that pressure tappings will not silting；Using taking source electromagnetism
Valve is damaged because air pressure is excessive when preventing from purging system road to pressure transmitter, it is ensured that pressure transmitter is normally pacified
Full work.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1. pressure transmitter, 2. takes source magnetic valve, 3. takes source ball valve, 4. purge solenoid valve, 5. purging ball valve, 6.

Specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, referring to Fig. 1, High water cut, ash-laden gas
Pressure-detecting device, it is characterised in that：The pressure that the bottom of aditus laryngis piston 7 in Venturi tube is located on converter gas Venturi tube 6 takes source
Tiltedly wealthy mouth source-taking apparatus 8 are installed, tiltedly the wealthy left end of mouth source-taking apparatus 8 arranges tiltedly wealthy mouth 9 at point, tiltedly wealthy mouth 9 is oblique upper left
Opening, the oblique end of wealthy mouth 9 insertion flue gas main pipeline about 15cm is in flue gas supervisor by being welded to connect；Oblique wealthy mouth source-taking apparatus 8
It is put into right-hand member to be connected with scavenging pipeline by purging ball valve 5, purge solenoid valve 4 is installed on scavenging pipeline, the Jing of purge solenoid valve 4 blows
Sweep pipeline connection Nitrogen source gases；Tiltedly the middle part of wealthy mouth source-taking apparatus 8 is welded take source capsule road straight up, is taken source capsule road and is passed sequentially through again
Source ball valve 3 is taken, source magnetic valve 2 is taken and is finally coupled to pressure transmitter 1.The oblique inclination angle of the oblique wealthy mouth 9 of the wealthy left end of mouth source-taking apparatus 8
B is 45 °.Described oblique wealthy mouth source-taking apparatus, to arrange obliquely, are 20 ° with the angle a of horizontal plane.
This practical High water cut dust-laden automatic blowing system purge process step is as follows：In normal operation purging ball valve 5 with take
Source ball valve 3 is in full-gear, when pressure is normally detected, takes source magnetic valve 2 and opens, and purge solenoid valve 4 is closed；Pipeline is purged
During state, take source magnetic valve 2 and close, purge solenoid valve 4 is opened.
The literary inlet and outlet pressure degree of accuracy of a text two is improved, the dust removing effects of primary dedusting system are not only effectively raised,
Realize clean manufacturing, and significantly reduce the fault rate of one-time dedusting blower fan and gas analysis system indirectly, improve and turn
Producer gas organic efficiency, is to realize that " negative energy " steel-making contributes.
Tiltedly wealthy mouth source-taking apparatus 8 can effectively prevent from being responsible for arm sewage stream in pressure tappings formation " moisture film ", it is ensured that pressure tappings are just
Normal open is suitable；Nitrogen timing purging control is carried out using purge solenoid valve, it is ensured that tiltedly sludge cannot deposit at wealthy mouth, it is ensured that pressure tappings
Will not silting；Wound is caused to pressure transmitter because air pressure is excessive when preventing from purging system road using the source magnetic valve of taking
Evil, it is ensured that pressure transmitter normal safe works.
Timesharing purging in the utility model programming has cleverly used the time difference to detect converter venturi pressure
Pipeline is effectively purged.
1st, pressure detecting flow process
The minimum place of technique upper tube wall flowing water is chosen before pressure takes source carries out perforate, installs tiltedly wealthy mouth oblique angle and takes source for 45 °
Device 8, oblique wealthy mouth is long-armed up during installation, and with oblique upper 20 ° of angles insertion installation is carried out, and further reduces tube wall water in main pipeline
Flow the impact to taking source mouth.
Pressure detecting state：Take source magnetic valve 2 to open, purge solenoid valve 4 is closed；
Official road purges state：Take source magnetic valve 2 to close, purge solenoid valve 4 is opened.
2nd, PLC control program
From PLC obtain it is electric, PLC control enter take source state, take source magnetic valve 2 and open, purge solenoid valve 4 is closed；Take
Magnetic valve 2 cumulative activation in source is closed after 100 minutes, while purge solenoid valve 4 is opened；Now PLC controls enter purging state, blow
Sweep after magnetic valve 4 works 20 seconds and close, while take source magnetic valve 2 open, into normally taking source state, such circular flow.
The utility model increased the operation of different pressures test point purging interval operation in 30 seconds, solve to have carried out a block converter
If the text of a text two imports and exports totally 4 pressure detecting points while purging is likely to result in other pneumatic equipments on identical Nitrogen source gases pipeline
The problem of normal operation is affected because of pressure step-down.
