Abstract
The utility model discloses a manhole of a lining plug for a settling vessel and a regenerator in a catalytic cracker; a reactor, a converter, etc. in a sulfur recovery device and a desulfurizing installation for an oil plant and a petrochemical plant. The manhole of the lining plug comprises a manhole flange cover, a lining plug, a manhole connecting pipe and a manhole flange, wherein, the manhole flange cover and the lining plug are of split structure, and the lining plug adopts a hollow structure. The utility model has the characteristics that the back part of the hollow lining plug adopts a straight cylinder structure of a round annular plate and lacing wires, the front part of the hollow lining plug adopts a conical cylinder structure, and the front part and the back part are fixedly connected into a whole. The utility model has the advantages that: the weight of the lining plug is reduced, thereby saving materials; a required rotating space for opening the manhole flange cover is reduced, thereby facilitating the opening of the manhole flange cover and the extraction of the lining plug; the conical structure of the front end of the utility model not only has functions of positioning and sealing the lining plug, but also can be used for a situation that internal medium is easily coked, thereby solving the problem that the lining plug can not be extracted because of coking, and facilitating maintenance and inspection of equipment.
Description
Technical field
The utility model belongs to a kind of petrochemical equipment accessory, on more specifically say so a kind of settling vessel that is used for refinery and petroleum chemical plant catalytic cracking unit, revivifier, riser tube, inclined tube, the flue and sulfur recovery facility, the reactor of desulfurizer, the lining Serb hole on the convertor.
Background technology
In oil and chemical plant installations, enter in tower or the container for ease of the people and to install, overhaul, to check, often have manhole on the housing.In refinery catalytic cracking unit, major equipments such as reacting-settler, riser tube, inclined tube, flue are because service temperature height (more than 500 ℃), and have catalyzer to wash away, and insulating and wearing-resistant lining is all arranged in its housing.And in sulfur recovery facility, desulfurizer, because high temperature and acid attack environment all have the heat-insulating acid-resisting lining in its housing.Correspondingly, its manhole is taken over and manhole plate, also lining should be set, and often adopts the structure of filling in the manhole plate belt material.At present, generally adopt manhole plate and straight barrel type lining plug to make the manhole of an integral body.This manhole plate exist weight big, open difficulty problems such as (after need all extracting long lining plug out, manhole plate just can Unscrews).Especially equipment such as the reacting-settler of catalytic cracking unit and riser tube also are difficult to open owing to coking causes manhole plate between lining plug and the manhole cylindrical shell owing to depressed Jiao of interior oil.The manhole that generally uses has increased difficulty, has strengthened workload, has brought very big inconvenience for the maintenance of appliance arrangement, inspection owing to there are the problems referred to above at present.
By retrieval, with the immediate prior art of the utility model be that the name that the applicant authorized on August 3rd, 2005 is called the Chinese utility model patent ZL200420084505.2 in " a kind of insulation Serb hole ", this patent has bigger improvement to the problems referred to above that exist, but still has the shortcoming that people's stopple weight is bigger than normal, open underaction.And the utility model patent application is just to the further improvement of the above-mentioned shortcoming of this patent, and shape all has substantial different with it with structure.
Summary of the invention
The purpose of this utility model is by adopting a kind of novel lining Serb pore structure, alleviate the weight in lining Serb hole greatly, and reduce and open the required revolution space of manhole plate, and solved well to the corrosive medium seal isolation with because the problem that coking causes the lining plug to be difficult to extract out, lining Serb port lid is opened easily, thus give equipment maintenance, check bring convenient greatly.
For achieving the above object, the technical solution adopted in the utility model is: this lining Serb hole, comprise manhole blind flange, lining plug, manhole adapter and manhole flange, its manhole blind flange and lining plug are for dividing body structure, the lining plug adopts hollow structure, its characteristics are that the rear portion of hollow liner plug adopts circular ring flat-plate, lacing wire straight barrel type structure, the anterior awl cylindrical structure that adopts, and front and rear portions is fixedly connected to be integral.
The circular ring flat-plate in the rear portion of described hollow liner plug, lacing wire straight barrel type structure are made up of the circular ring flat-plate of hollow liner plug rearward end, several strip lacing wire and gusset, circular ring flat-plate is linked to be integral body to several strip lacing wires, adds that the gusset three is fixedly connected into an inflexible straight barrel type structure.The front portion awl cylindrical structure of described hollow liner plug is made up of awl tube and lining.The front end of hollow liner plug is provided with acidproof or heat insulation lining, fills the fine pad of making pottery between the ring flat-plate of rearward end and the manhole plate, has been compressed the sealing heat-blocking action by manhole plate.For with the corresponding and coupling of awl tube of the front portion of described hollow liner plug awl cylindrical structure, the manhole of equipment or pipeline is taken over the end and is connected an external conical-tube that is complementary with lining plug inner conical-tube, has the fine pad sealing of making pottery heat insulation between lining plug inner conical-tube and the external conical-tube.
The utility model divides the lining Serb hole of body structure, because circular ring flat-plate, strip lacing wire straight barrel type structure are adopted in the rear portion of hollow liner plug, and the anterior awl cylindrical structure that adopts, its advantage one is the weight saving of lining plug and saves material; The 2nd, passage strengthens, and has reduced and has opened the required revolution space of manhole blind flange, has made things convenient for that the manhole blind flange is opened separately, the independent extraction of lining plug; The 3rd, front end tapered structure wherein both can play location and sealing function to the lining plug, can be used for again the easy coking of interior media occasion, avoided since coking cause the lining plug can't extract problem out, reduce the workload and the work difficulty of overhaul of the equipments, be very easy to the maintenance and the inspection of equipment.
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
