Background technology
In refinery catalytic cracking unit's energy-recuperation system, third level cyclone separator (being called for short three revolves) is one of its key equipment.Present three revolve structural shape mainly contains two kinds: multitube vertical three revolves, and multitube horizontal three revolves.In recent years, the catalytic cracking unit technical development of China was very fast, and device constantly maximizes, and the intermingled dregs ratio of raw material constantly increases, and burnt temperature and was also improving, and it is very unstable that the operation of device becomes, and three of many oil plants screw out and showed variety of issue.At present China's multitube three is revolved the subject matter that occurs in the running has: 1. three to revolve whole efficiency low, and the part single tube is not worked, back-mixing; 2. single tube and three revolves the dust-exhausting port fouling; 3. the single tube crushing catalyst increases three back-out mouthful fine powders; 4. single tube serious wear; 5. expansion joint distortion, cracking; 6. three of high throughput revolve manufacturing processing and maintenance replacing difficulty.
By retrieval, relevant with the utility model prior art is CN2526075Y, CN2568308Y, GB2330786A and CN1168301A.Wherein preceding two patents are employing and do not revolve the multitube third level cyclone separator of branch single tube as resolution element with wear resistance lining, easily cause service life short after the wearing and tearing, simultaneously owing to adopt the single tube combination, processing capacity is big, investment is high, yielding, and the wearing and tearing behind efficiency can reduce, in structure with the two all has in essence difference with the utility model in shape; GB2330786A has described a kind of gradation device of cyclone type, and CN1168301A has described the gas-solid quick disconnector of a kind of riser fluidized reaction system spiral-flow type, and the two all has in essence different with the utility model on principle, structure and purpose.
Summary of the invention
The purpose of this utility model just is the problems referred to above of revolving at multitube three, by improving structural design, develop a kind of novel third level cyclone separator, make this novel three to revolve and to solve multitube three and revolve catalyst back-mixing and pulverizing problem, improve the combined efficiency in the industry use, satisfy the cigarette machine and revolve the requirement of separative efficiency three, and want stable operation, life-span long, make and maintenance is changed conveniently, and revolve than traditional multitube three and to reduce investment outlay.
In order to achieve the above object, the technical solution adopted in the utility model is: this third level cyclone separator, comprise housing, exhanst gas outlet, smoke inlet, central tube, many single branch and the parting boads of revolving, its characteristics are to be equipped with many single branches that revolve in housing; Many the single branches that revolve are installed in the housing by the syndeton support suspention with parting boad and central tube; Enclosure interior is separated into inlet plenum, collection chamber and three relatively independent spaces of dust storage chamber.
Housing in this third level cyclone separator is made up of cover head, cylindrical shell and bottom cone, and cylindrical shell is provided with handling hole; Central tube and each single uniform linking to each other of inlet of revolving branch, the distance that subentry has 200mm～2000mm is revolved with single in central tube bottom; Its parting boad is made up of one section flat partition board and one section awl dividing plate; Wherein every single branch that revolves all has the high-strength abrasion-proof lining; Every single branch and parting boad employing plug-in type angle welding syndeton of revolving adopts rectangle butt weld syndeton with central tube.
Revolve with multitube three and to compare, this revolving as the shell dress formula three of the integrated suspension structural shape of resolution element with single cyclone separator has the following advantages: 1, air inlet distributes rationally evenly, the combined efficiency height, pressure drop is low, can in long-term the use, keep high-performance, effectively guarantee the operational stability and the long period safe operation of device; 2, avoided three to revolve wearing and tearing and the pulverizing of single tube, reduced the fouling of cigarette machine blade, can improve the serious problem of present domestic cigarette machine blade fouling greatly catalyst in the flue gas, significant to guaranteeing the operation of cigarette captain phase stability and safety; 3, all be with the high-strength abrasion-proof lining owing to revolve branchs, and three structures of revolving entire arrangement and integrated suspension structural shape make the thermal expansion of crucial internals and stressedly more become reasonable, thereby prolonged for three service lifes of revolving as every of separation assembly; 4, because structure advantages of simple has more reduced manufacturing and difficulty of construction, shortened construction period, and be convenient to from now on maintenance, transformation and replacing; 5, under same treating capacity, can save equipment investment, maintenance in the use and renewal cost also can reduce greatly.
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Description of drawings
