Abstract
The utility model discloses a pressure-guide sedimentation device which includes a tank body. The tank body is provided with a top cover and a bottom cover which are sealed. One side of the upper part of the tank body is provided with a drainage pipe communicated with the bottom of a fractionating column; the opposite side of the upper part of the tank body is provided with a blowpipe; an intake valve is arranged on the blowpipe; one side of the lower part of the tank body is provided with a discharge pipe; a discharge valve is arranged on the discharge pipe; and the top cover of the tank body is provided with a pressure-guide pipe used for mounting a detecting and measuring instrument. As the detecting and measuring instrument is arranged on the top of the tank body, while the drainage tube is arranged on the upper part of the tank body, the drainage pipe and the area, on which the pressure-guide pipe is located and used for mounting the detecting and measuring instrument, are hard to be blocked. The pressure-guide sedimentation device has simple structure and long service life.
Description
Technical field
The utility model relates to a kind of impulse sedimentation device that is used for the fractionating column bottoms level monitoring of catalytic cracking unit.
Background technology
At present, liquid level generally uses float-ball type liquid level gauge and two flange form liquid level gauge to realize the monitoring of biliquid position at the bottom of the fractionation Tata of catalytic cracking unit, and the influence of float-ball type liquid level gauge because of falling ball, card ball and being stirred factor such as steam impulsion, its measured value is general not as the control input quantity of liquid level, but utilizes the input quantity of two flange liquid level gauge measured values as control loop.But, because of fractionator bottom temperature higher, even if the two flange liquid level gauges of high temperature also need be installed sealing chamber, contain catalyst because of oil at the bottom of the fractionating column again, sealing chamber will stop up in use for some time, when serious root valve all close not dead, to such an extent as to can't handle and normal the use.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of instrumentation that makes things convenient for and detects, and signal piping is difficult for stopping up, the impulse sedimentation device of the fractionating column bottoms level monitoring that is used for catalytic cracking unit of long service life.
For solving the problems of the technologies described above, the utility model comprises tank body, and its design feature is top cover and the bottom that described tank body has sealing, is provided with the drainage tube that is communicated with the fractionating column bottom in tank body top one side, relative opposite side is provided with gas blow pipe, and gas blow pipe is provided with intake valve; One side is provided with blow-off pipe in the tank body bottom, and blow-off pipe is provided with blowoff valve, and the tank body top cover is provided with the pressure guiding pipe that is used for the installation and measuring instrument.
Described drainage tube and gas blow pipe are on same axial line, and the internal diameter of drainage tube is greater than the internal diameter of gas blow pipe.
Described blow-off pipe is on the vertical plane of drainage tube and gas blow pipe place fore-and-aft plane.
Be provided with decontamination orifice on the tank body bottom, the end of decontamination orifice is provided with openable closing means.
After adopting said structure, after catalyst at the bottom of the fractionating column in the oil enters into tank body with oil along drainage tube, under the gravity effect, sink to the middle and lower part of tank body gradually, because instrumentation is arranged on the top of tank body, and drainage tube is in tank body top, so drainage tube and the pressure guiding pipe region that is used for the installation and measuring instrument be difficult for to be stopped up.If when the dirt that is formed by catalyst in the tank body reaches a certain amount of, can open intake valve and blowoff valve, utilize steam blowback number minute can clear up, can open the closing means of the end of decontamination orifice in case of necessity and thoroughly clear up.It is simple in structure, long service life.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
