Description
Technical field
The invention belongs to the technical fields of petrochemical industry instrument measurement, and in particular to a kind of block-resistant type catalysis flue gas turbine inlet pressure
Power stably measured device.
Background technology
The smoke machine of catalytic cracking unit is energy-saving equipment important in petrochemical industry, and the medium in inlet duct is from catalysis
Regenerator comes out the flue gas Jing Guo three supination, and not only temperature is high（About 660 DEG C）, and catalyst fines and flue dust are carried,
Contain CO simultaneously2、N2、SOX、NOXAnd water vapour.Existing pressure measurement method is that one pressure of setting is short at close walling of flue
It manages and is connected inside flue, external root gate valve is connected by pipeline with pressure transmitter.But dust-laden high-temperature flue gas exists
Stagnant area is generated when flowing through one end that pressure pipe stretches into flue, catalyst dust and water meeting deposition are in pressure pipe, through excessively high
Temperature sintering, measuring pressure passage are gradually reduced, and pressure measurement is inaccurate, with the extension of time, it is final completely plugged, lead to pressure measurement
Failure can only wait for shut-down removal procedure even if taking hydraulic pump to be difficult to dredge suppressing the method for dredging, and it is long to influence catalysis smoke machine
The measurement of pressure when periodic duty.
Invention content
Based on the above the deficiencies in the prior art, technical problem to be solved by the present invention lies in provide a kind of block-resistant type catalysis
Flue gas turbine inlet pressure stability measuring device, to solve asking for pressure measurement pipeline easily blocking and pressure measurement inaccuracy in the prior art
Topic.
In order to solve the above-mentioned technical problem, the utility model provides a kind of block-resistant type catalysis flue gas turbine inlet pressure stability measurement
Device comprising pass through the purification wind vacuum tank of pipeline connection, blowback gate valve, permanent flow valve, spinner flowmeter, exhaust-valve, introducing
Shut-off valve, pressure transmitter, flue root valve, pressure short tube, high-temperature flue.The outlet end pipeline of the spinner flowmeter is divided to two
Road, the first via pass sequentially through pipeline and are connected to the flue root valve, pressure short tube, high-temperature flue, the second road and the introducing
Shut-off valve, pressure transmitter pass sequentially through pipeline connection.
Based on the above technical solution, the present invention can also be improved as follows.
It is described introduce shut-off valve arrival end be connected with the arrival end of the exhaust-valve, the outlet end of the exhaust-valve and
Air is connected, and to check whether pipeline is unobstructed and empties impurity, prevents impurity retaining pressure transmitter.
Further, the purification wind vacuum tank provides pressure 0.5-0.6kg/cm2（Gauge pressure）Purification wind as back-blowing,
Not aqueous and corrosive impurity.
Further, the pressure short tube stretches out 10-20mm to high-temperature flue inner wall, prevents pressure short tube blocked inlet.
Compared with prior art, the invention has the advantages that former pressure measuring unit is introduced 0.5-0.6kg/cm by it2（Table
Pressure）Purification wind carry out blowback, the flow of back-blowing is controlled by permanent flow valve and spinner flowmeter, air quantity is more than critical pressure,
Pressure pipeline is kept to remain unobstructed.By spinner can intuitive judgment pressure pipeline it is whether unobstructed and whether flow steady
It is fixed, high-temperature dust-containing flue gas felt jam pressure pipeline can be eliminated, ensures that the precision of pressure measurement is not influenced by blowback.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and being implemented in accordance with the contents of the specification, and in order to allow the above and other purpose, feature of the utility model
