Abstract
The utility model relates to the technical field of boilers, particularly a novel anti-abrasion fin type coal economizer. A middle fin is welded above the middle part of the front two rows of windward pipes; a fin is respectively welded on the left and right sides of the middle fin; an included angle of 32-38 degrees is formed by the two side fins and the middle fin; and the two side fins and the middle fin integrally form a Y shape. The coal economizer has simple structure, and solves the problem of abrasion in the coal economizer by changing the structure form of the coal economizer. On the premise of not raising the manufacturing cost, the utility model prolongs the service life of the coal economizer more than twice, and thus, has great economic benefit.
Description
Affiliated technical field
The utility model relates to the boiler technology field, is specifically related to a kind of novel abrasionproof finned-tube economizer.
Background technology
Economizer is the vitals in the boiler product, generally be arranged in the afterbody of boiler, in medium and small boiler, especially the wearing and tearing of the economizer in the Small and Medium Circulating Fluidized Bed Boiler are very severe, service life is shorter, that have even can only use some months, have a strong impact on the normal operation of boiler, bring about great losses for power plant and boiler user, this is the more scabrous difficult problem of field of boilers, in order to solve wearing and tearing, common way is to use than good material to install abrasion-proof cover plate additional in the windward side of economizer tube, after operation a period of time, and blowing out, change abrasion-proof cover plate again, install abrasion-proof cover plate additional and have certain shortcoming, abrasion-proof cover plate material requirements height, price is higher, just need blowing out to change cover plate after the boiler operatiopn short time, the influence operation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the novel abrasionproof finned-tube economizer that a kind of version is simple, can well solve wear problem is provided.
The technical solution of the utility model is:
A kind of novel abrasionproof finned-tube economizer, the facing the wind body middle upper part of facial canal of the front row of economizer is welded with fin in the middle of a slice, middle fin each side be welded with a slice fin, between both sides fin and middle fin structure in an angle, the both sides fin of welding and middle fin integral body are the goat's horn fork-shaped.
The angular range that constitutes between described both sides fin and middle fin is 32 °-38 °.
The beneficial effects of the utility model:
The utility model is simple in structure, by having changed the version of economizer, has well solved the wear problem of economizer, and the utility model is under the prerequisite that does not improve manufacturing cost, and the service life of having improved economizer, economic benefit was very huge more than 2 times.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of novel abrasionproof finned-tube economizer, preceding two rows of this economizer body 1 middle upper part of facial canal down with the wind are welded with the middle fin 2 of a slice, middle fin 2 with flue gas 3 minutes to both sides, weld two fins 4 again in 35 ° of places apart from the both sides of middle fin 2, integral solder becomes the goat's horn fork-shaped, behind the flue gas 3 middle fins 2 of process and 4 shuntings of both sides fin that get off from above, flow to the side, rather than directly tangential 1, two group of tube panel of erosive wear pipe is arranged in juxtaposition, and the flue gas that flows to the side meets between tube panel and tube panel, offset portion of energy each other, flow through from pipe row middle 5 then, will reduce the wearing and tearing of economizer, the economizer of same material greatly like this, after adopting this structure, the life-span all improves more than 2 times.
Claims (2)
