Description
Technical field
The present invention relates to the inner member for fractionating column of petrochemical industry, furtherly, relate to a kind of on-line cleaning device and method of tank type liquid distributor.
Background technology
The isolation technics that tower packing technology is petroleum refining, the industry such as petrochemical industry, Coal Chemical Industry, food and pharmacy extensively adopts.Tank type liquid distributor has the features such as liquid distribution is even, operating flexibility large, anti-clogging anti-coking performance is strong, and be widely used in filler fractionating column, the development of its technology also promotes the progress and development of tower packing technology.
In the last few years, in the practical application in industry process of filler fractionating column, often occur that the mechanical admixture in distribution medium, ash content, greasy filth, corrosion thing etc. are deposited in the secondary distributing slot of tank type liquid distributor, particularly lighter material, the secondary distributing slot of tank type liquid distributor can be full of time serious, cause liquid distribution deleterious, to such an extent as to device cannot normal production operation.Such as, wuhan petrochemical industry is after process units runs one-period, and maintenance finds that the liquid distribution trough secondary distributing slot of decompression distillation top of tower I, II section filler is almost deposited thing and fills up; Plant of Tianjin Petrochemical Company also finds identical phenomenon when turnaround of unit.
At present, when this problem can only pass through device shut-down (breakdown) mainteance, artificial treatment is adopted.This not only have impact on the normal production of device, adds difficulty also to the shut-down (breakdown) mainteance of device.
Summary of the invention
For solving the problems referred to above that prior art exists, the invention provides a kind of on-line cleaning device and method of tank type liquid distributor, can realize not needing device to stop, realize the Hand scarf of liquid distribution trough at short notice; Effective, be conducive to giving full play to device potential, the stable long-term operation of assurance device, improve the economic benefit of manufacturing enterprise.
The on-line cleaning device of a kind of tank type liquid distributor of one of the present invention, is arranged on tank type liquid distributor, and described device comprises: rinse house steward 3 and rinse arm 4; When installing this device, this area common method can be adopted, as described in rinse one end of house steward 3 and connect with the ozzle 2 be arranged on tower wall, the other end is fixedly connected with Ta Bi, specifically can be fixed on the bearing inside tower wall; The secondary distributing slot 6 of tank type liquid distributor hangs to be fixed on and rinses on house steward 3;
Described flushing house steward 3 is as the hanging beam of secondary distributing slot 6; Described flushing house steward 3 one or both sides can be provided with suspended structure, for connecting and fixing described secondary distributing slot 6; Described suspended structure can be the conventional structure in this area, as hanger 5.
Described flushing arm 4 one end is communicated with flushing house steward 3, and the other end can extend into bottom secondary distributing slot 6.
One end mouth of pipe that described cleaning arm 4 extend into bottom secondary distributing slot 6 can be closed, and is provided with flushing hole 8 on the tube wall near the mouth of pipe.
In concrete enforcement, can be preferred:
When arranging the position rinsing arm 4, for the secondary distributing slot 6 rinsing house steward 3 process, described flushing arm 4 can be vertically connected on and rinse below house steward 3, rinses arm 4 end and stretches into bottom secondary distributing slot 6; And in tower marginal portion, for rinse house steward 3 without secondary distributing slot 6, can will rinse arm 4 from flushing house steward 3 side draw, according to space structure situation turn, end stretches into bottom secondary distributing slot 6.Cleaning fluid is sprayed in the horizontal direction by flushing hole 8 and rinses bottom second-level groove.
The quantity of described flushing hole 8 can be preferably two, along secondary distributing slot 6 groove to the both sides being symmetricly set in cleaning arm 4.Flushing liquor is sprayed in the horizontal direction from flushing hole 8, rinses bottom second-level groove.
Described flushing hole 8 is preferably circular or square opening;
The equivalent diameter of described flushing hole 8 is Ф 6-Ф 10;
Described flushing house steward 3 according to the structural design situation of tower diameter size and secondary distributing slot, can be arranged more than one or two, while its main target is the cleaning requirement of meeting tier 2 distributing slot 6, also will meet the hanging requirement to secondary distributing slot 6.Flushing liquor is introduced in tower, symmetry or unsymmetric form can be adopted to be connected with flushing house steward 3 according to tower diameter size, tower interior spatial structure situation.More than two or two situations of rinsing house steward 3, each to rinse between house steward 3 can at Ta Nei or tower be outer is connected by pipeline.The caliber of described flushing house steward 3 determines according to flushing liquor consumption and secondary distributing slot lifting requirements, generally can select DN50 ~ DN150; The caliber of described flushing arm 4 generally can be DN10 ~ DN20.
A kind of tank type liquid distributor cleaning method of the present invention two utilizes the described device of one of the present invention to clean liquid distribution trough; Described method comprises described flushing liquor and enters flushing house steward 3 through ozzle 2, then enters flushing arm 4 by flushing house steward 3, finally by ejection in flushing arm 4, carries out the flushing to secondary distributing slot 6.
Cleaning fluid is sprayed by circular or microscler flushing hole 8 in the horizontal direction and rinses bottom second-level groove, and the deposits such as the greasy filth broken up, dirt flow out or distributing slot top spilling from distributor aperture with liquid, reach sedimental object in on-line cleaning distributing slot.
Described flushing liquor is preferably not less than 1 meter per second from the flow velocity rinsing ejection arm 4, being rinsed well by the deposit in distributing slot within a short period of time.
The flushing oil that described flushing liquor can adopt this area conventional, specifically can adopt the oil that withdrawing oil liquid distribution trough distributes more, enter under stress in tower and complete flushing task, control to complete flushing with less washing time, in order to avoid bring larger fluctuation to production operation.Withdrawing oil can be preferably.
Feature of the present invention:
1, described secondary distributing slot 6 hangs to be fixed on and rinses on house steward 3, and described flushing house steward 3, in order to replace the hanging beam of groove type distributor, not increasing the inner space of tower, also reducing the equipment investment brought because arranging online cleaning structure.
2, for the secondary distributing slot 6 rinsing house steward 3 process, arrange bottom described flushing house steward 3 and rinse arm 4 and go deep into bottom secondary distributing slot 6; And in tower marginal portion, rinse house steward 3 without secondary distributing slot 6, can will rinse arm 4 from flushing house steward 3 side draw, according to space structure situation turn, end stretches into bottom secondary distributing slot 6.
3, flushing arm 4 gos deep into the end in secondary distributing slot 6, and in bottom along groove to horizontal direction perforate, cleaning fluid is sprayed in the horizontal direction by flushing hole 8 and rinses bottom second-level groove, improves flush efficiency.
Tank type liquid distributor cleaning device structure of the present invention is simple, and economical, does not increase the inner space of tower.Tank type liquid distributor cleaning device of the present invention and method effectively can remove the deposit that tank type liquid distributor in use produces, improve the liquid distribution effect of tank type liquid distributor, the operation of stabilizer, in the production operation cycle of extension fixture, has good application prospect.
