Abstract

The utility model relates to a barrel type slag cooler for boilers, which comprises a support, an water inlet pipe, a water outlet pipe, a plurality of cool-dregs tubes, a driving device and a drum; the drum comprises a cooling chamber, a slag sharing chamber and a slag tapping chamber; the drum is driven by the driving device. The cool-dregs tubes are evenly distributed in the cooling chamber; each cool-dregs tube is fixed separately to facilitate the replacement of single cool-dregs tube. Part of the cool-dregs tubes in the slag sharing chamber are cut to form a plurality of flute profile ports to facilitate the entering of hot slag. A cooling pipe is arranged in the cool-dregs tube, the cooling area is increased, and the cooling effect is improved. A slag inlet pipe enters deeply into the slag sharing chamber by a athodyd combustion chamber; the top end of the slag inlet pipe is a slag inlet, the bottom of the slag inlet pipe is not fixed and is corresponding to the flute profile end of the cool-dregs tube; a plurality of slag outlets with the number corresponding to the number of the cool-dregs tubes are arranged on the wall of the drum of the slag tapping chamber. When the water is cooled, the athodyd combustion chamber, the slag sharing chamber, the cooling chamber and the slag tapping chamber form an air cooling channel to perform air cooling. The utility model has the advantages of simple structure, easy assembly, large cooling area, good cooling effect, convenient maintenance and long service life of the equipment.

Description

Barrel slag cooler

(1) technical field

The utility model relates to the equipment that a kind of high-temperature ash that boiler is discharged is cooled off, a kind of specifically barrel slag cooler.

(2) background technology

There is following problem in existing barrel slag cooler: (1) slag feeding chamber maintains static, the hot stack of temperature up to 900 ℃ is in slag feeding chamber, form heat and concentrate, slag feeding chamber damages easily, and easily stops up, film-cooled heat little (2) is although polygonal scum pipe welds together, increased film-cooled heat, but weld seam is many, fragile, can't singlely change after scum pipe is bad, entire equipment is just scrapped; (3) structural design is unreasonable, and in use, to damage phenomenon more because of mechanical fatigue.

(3) summary of the invention

At the deficiencies in the prior art, the utility model provides that a kind of good cooling results, slag input are difficult for stopping up, barrel slag cooler easy for installation, easy to maintenance.

The technical solution of the utility model realizes in the following manner: barrel slag cooler, comprise support, water inlet pipe, outlet pipe, cold slag tube, drive unit, cylinder, and cylinder comprises cooling chamber, equal grit chamber, slag removing chamber, cylinder is driven by drive unit.

Cold slag tube is evenly distributed in the cooling chamber, and all the part of pruning of the cold slag tube in the grit chamber forms flute profile, helps being entered in the cold slag tube by the warm sludge that slag feed pipe enters; Cooling tube is arranged in the cold slag tube, and the cooling tube two ends reach outside the cold slag tube, communicate with cooling water cavity, and cooling tube directly contacts with warm sludge in cold slag tube, play cold slag and lead slag; Return pipe in the cooling water cavity communicates with outlet pipe.

Slag feed pipe is deep in the equal grit chamber by wind sucting chamber, and the slag feed pipe top is a slag inlet, and the bottom is unfixing, and the bottom is corresponding with the flute profile mouth end face of cold slag tube; Have on slag removing chamber's cylinder wall and the corresponding slag notch of cold slag tube number.

Among the figure: 1 is that support, 2 is that slag feed pipe, 3 is that slag inlet, 4 is that cold slag tube, 5 is that slag notch, 6 is that cooling chamber, 7 is that drive unit, 8 is that water inlet pipe, 9 outlet pipes, 10 are that return pipe, 11 is that front apron, 12 is that front tube sheet, 13 is that back tube sheet, 14 is that inlet scoop, 15 is that cooling tube, 16 is that cooling water cavity, 17 is that slag removing chamber, 18 is that equal grit chamber, 19 is that wind sucting chamber, 20 is that cylinder, 21 is that flute profile mouth, 22 is a swivel joint.

(5) embodiment

This barrel slag cooler comprises support 1, water inlet pipe 8, outlet pipe 9, cold slag tube 4, drive unit 7, cylinder 20, and cylinder 20 comprises cooling chamber 6, equal grit chamber 18, slag removing chamber 17; Cylinder 20 tilts to be installed on the support 1, is driven by drive unit 7.

Cold slag tube 4 is evenly distributed in the cooling chamber 6, and every cold slag tube 4 is fixing separately, for must be convenient to single replacing when a certain cold slag damages.All the part of pruning of the cold slag tube in the grit chamber forms flute profile mouth 21, and the warm sludge of being convenient to be entered by slag feed pipe 2 directly enters in the cold slag tube 4; Cooling tube 15 in the cold slag tube 4 directly contacts with warm sludge, plays cold slag and leads slag.

Slag feed pipe 2 bottoms are unfixing, overcome the harm of expanding with heat and contract with cold equipment being caused; The slag feed pipe bottom is deep into equal grit chamber 18, and corresponding with the flute profile mouth 23 of cold slag tube 4, along with the rotation of cylinder 20, lime-ash enters in the different cold slag tube 4 successively, has solved warm sludge in front end accumulation, blocking problem.

Every cold slag tube 4 is fixed on front apron 11, front tube sheet 12, the back tube sheet 13 simultaneously, and front apron 11, front tube sheet 12 constitutes equal grit chamber 18, and the cold slag tubes 4 in the slag removing chamber 17 are fixed on the back tube sheet 13, and corresponding with it slag notch 5 is arranged, make slag tap smooth and easy.

Cooling tube 15 two ends reach outside the cold slag tube 4 by bend pipe, communicate with cooling water cavity.Return pipe in the cooling water cavity communicates with outlet pipe, and water inlet pipe 8 and outlet pipe 9 are installed on the same swivel joint 22, have reduced the setting height(from bottom) of equipment, have saved the space.

Below in conjunction with accompanying drawing, the course of work of barrel slag cooler of the present utility model is elaborated:

Warm sludge from slag inlet 3 through slag feed pipe 2, enter the flute profile mouth 21 of cold slag tube 4 in the equal grit chamber 18, rotation along with cylinder 20, warm sludge enters different cold slag tube 4 successively, and the slag on cold slag tube 4 tops falls under the effect of gravity, because cylinder 20 tilts to install, and revolution continuously under the effect of drive unit 7, slag can slide a segment distance in cold slag tube 4, along with the continuous revolution of cylinder 20, until being slipped to lower end slag notch 5.

In the process of landing, cooling water is got back to outlet pipe 9 from return pipe 10 in water inlet pipe 8 enters cooling water cavity 16 and cooling tube 15 cooling chamber 6.Warm sludge in the cold slag tube 4 directly contacts with cooling tube 15, and cold slag tube 4 cold water abundant and in the cooling water cavity 16 in cooling chamber 6 contacts, and through supercooling, the warm sludge that enters becomes cold slag, comes out from slag notch 5.

Wind sucting chamber 19 is fixed on the support 1, communicate with equal grit chamber 18, the warm sludge that equal grit chamber 18 will not enter cold slag tube 4 blocks, and makes it enter each cold slag tube 4 uniformly, simultaneously, all the top of grit chamber 18 is vacant, be easy to ventilate, wind enters from slag removing chamber 17, enters wind sucting chamber 19 through cooling chamber 6, equal grit chamber 18, come out by inlet scoop 14, slag is carried out air cooling.
