Abstract
The utility model discloses a central cylinder of an air-cooled whirlwind separator, the wall of the central cylinder is alternately spliced by a plurality of laminated hollow air in-out casting, the top of the laminated hollow air-in casting is connected with an air-in pipe through an annular air-in connecting box, the top of the laminated hollow air-out casting is connected with an air-out pipe through an annular air-out connecting box, the bottom of the laminated hollow air in-out casting is connected together through a middle annular connecting box. The central cylinder of the air-cooled whirlwind separator in the utility mode can lower the operating temperature of the whirlwind separator central cylinder, increase the application rigidity, decrease the thermal deformation and facilitate the overhaul; during the replacement of the damaged parts, the replacing of the whole central cylinder is not needed, while only the partial replacing is needed to complete the overhaul by untiing the casting of the damaged parts and removing the pothook. The hot air from the air-out connecting box can be used for spreading or conveying coal wind to coal pipe. Due to the splicing structure for decentralizing the stress, the thermal deformation is further reduced.
Description
Technical field
The utility model relates to a kind of separator central tube, specifically a kind of ventilation type cyclone separator central tube of being convenient to safeguard.
Background technology
At present, to cyclone separator central tube service life of existing CFBB usually in 2～3 years, its reason be because: 1, central tube environment of living in is at 900～1000 ℃; 2, granule density height, the flow velocity carried secretly in the flue gas are fast, serious wear; The corrosive gas that 3, sulfur-bearing is arranged in the flue gas; 4, finally cause central tube generation permanent deformation under the long-term operation mechanism.Central tube after the distortion not only influences the separative efficiency of cyclone separator, but also influences boiler load, increases the wear extent of back-end ductwork and the burden of deduster simultaneously.Generally, central tube damages the back boiler and can not move, the effort of taking a lot of work especially in the replacing process, and the time between overhauls(TBO) is long, investment is big, and construction belongs to high-risk operations.
The utility model content
Technical problem to be solved in the utility model provides a kind of ventilation type cyclone separator central tube of being convenient to safeguard at the existing in prior technology defective, this central tube can keep relative low temperature in hot environment, so that improve self hardness and reduce thermal deformation, also easy access and replacing of this central tube in addition.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of ventilation type cyclone separator central tube, its wall of central tube is formed by number of plate-shaped hollow turnover gas foundry goods alternative splicing, and the upper port of described sheet hollow air inlet foundry goods connects air inlet pipe by annular air inlet header; The give vent to anger upper port of foundry goods of described sheet hollow connects escape pipe by the annular header of giving vent to anger; Described sheet hollow turnover gas foundry goods lower end links together by the intermediate annular header.
Described sheet hollow turnover gas foundry goods all hangs on the fixture of central tube by hook.
Its outside wall surface mid portion of described central tube is set up annular opotism.
Backplate is set up in the outside of described central tube bottom intermediate annular header again, uses casting material to fill in the space between backplate and intermediate annular header.
Adopt the local welding mode between the described sheet hollow turnover gas foundry goods, adopt the connected mode of full weld between each annular header and the sheet hollow turnover gas foundry goods.
A kind of ventilation type cyclone separator central tube of the present utility model compared with prior art has following beneficial effect:
A kind of ventilation type cyclone separator central tube of the present utility model reduces cyclone separator central tube serviceability temperature, improves practical hardness, reduces thermal deformation;
Convenient maintenance, when changing damaged position, needn't the integral replacing central tube, only need the foundry goods at damaged position is untied, and remove hook and carry out local replacing and can finish maintenance;
The hot-air that comes from outlet header can be used as uses such as coal-feeding tube coal spread wind or defeated coal wind;
Owing to be that splicing construction can dispersive stress, reduce thermal deformation once more.

The specific embodiment
Extremely shown in Figure 7 according to Fig. 1, a kind of ventilation type cyclone separator central tube, its wall of central tube is formed by number of plate-shaped hollow turnover gas foundry goods 11 and 12 alternative splicings, cold air connects with annular air inlet header 4 by air inlet pipe 3, air flows to intermediate annular header 9 from top to bottom by sheet hollow air inlet foundry goods 11, flow into the annular header 2 of giving vent to anger from bottom to top through converging again by the sheet hollow foundry goods 12 of giving vent to anger, after escape pipe 1 flow out, wherein sheet hollow turnover gas foundry goods 11 and 12 adopts local welding 13 structures, and each annular header and sheet hollow turnover gas foundry goods 11 or 12 adopt the connected mode of full weld.
Reduced the central tube wall temperature through the heat exchange of this cold air, improved material and use hardness, reduced thermal deformation simultaneously, elongation center's tube service life.
Secondly, be convenient maintenance, all adopt hook 5 formula structures at above-mentioned number of plate-shaped hollow turnover gas foundry goods 11 or 12, each foundry goods hangs on the fixture 6 of central tube by linking up with 5, because sheet hollow turnover gas foundry goods 11 and 12 is alternative splicings, so the air reverses in the adjacent foundry goods, final integral is spliced into circle.
At last, be circular configuration for guaranteeing integral body, set up the feature of annular opotism 7 at mid portion again with the unitary circular of maintenance central tube; Set up again in backplate 8, the space between backplate 8 and intermediate annular header 9 in central tube bottom, smoke inlet place-be and to use casting material 10 to fill,, prolong its service life with protection intermediate annular header 9; For reducing wear each hollow sheet foundry goods is made flakey, and direction conforms to the flow of flue gas direction.
