Abstract
The invention discloses a dust removal chamber for an economizer. A dust remover comprises an ash bucket, a door plate, a dust discharging door and a partition plate, wherein the ash bucket is welded on the lower side of an economizer body; the door plate is fixed with the dust discharging door through a bolt and a nut; the partition plate is fixed in the middle of the ash bucket through a partition plate limiting block on the inner side of the ash bucket, so that the ash bucket is partitioned into a left space and a right space; the partition plate is lower than the ash bucket; and reinforcement ribs are welded on the partition plate. According to the mode, the partition plate is arranged in the middle of the conventional dust removal chamber, so that gas flow at a tail gas outlet of a boiler gets into or gets out of two ends of the economizer; and heat can be transmitted to a water pipe as much as possible, hot water produced by the heat is used fully, and effects of saving fuels and energy are achieved; a dust removal chamber and the dust discharging door are arranged on the lower part of the economizer, so that dust in the tail gas can be cleared away timely, and the economizer of the boiler can be kept smooth; and therefore, the service lives of the economizer and the dust removal chamber are prolonged.
Description
Technical field
The present invention relates to the dirt pocket field, particularly relate to a kind of dirt pocket that is used for economizer.
Background technology
Economizer and dirt pocket are two kinds of indispensable equipment of Industrial Boiler, and the former establishes for energy-conservation, and the latter is the needs of environmental protection.
Conventional boiler is made up of body of heater and the drum that is arranged on the body of heater top, and this boiler is to make the fuel combustion in the burner hearth through burner, comes burner hearth is heated; Can produce a large amount of tail gas during burning; Because the difference of combustion medium, exhaust temperature is generally at 200～300 ℃, in order to cut the waste; Adopt the method that economizer is installed to absorb the heat in the tail gas, reach the purpose of energy savings.The traditional economizer of middle-size and small-size Industrial Boiler is the cast iron fin type, for folding the assembling of formula.This economizer is prone to fouling, and the efficient of stifled ash back economizer subtracts greatly, and resistance heightens, even it is often also of no avail that soot blower is set, not only influences heat exchange, also disturbs the air draft of boiler, reduces the operating efficiency of boiler.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of dirt pocket that is used for economizer, can in time clear up the dust in the economizer, makes full use of the heat in the tail gas, has the effect of fuel savings, energy savings, has prolonged economizer service life.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of dirt pocket that is used for economizer is provided, and said deduster comprises: ash bucket, door-plate and dust discharge door, said ash bucket are welded on economizer body downside; Said door-plate is fixed through bolts and nuts and dust discharge door; Said deduster also comprises a dividing plate, said dividing plate in the middle of the inboard dividing plate limited block of ash bucket is fixed on ash bucket, two spaces about ash bucket is divided into; The height of said dividing plate is lower than the height of ash bucket, is welded with reinforcement on the said dividing plate.
In preferred embodiment of the present invention, each all is provided with screw hole to said door-plate in the upper and lower part, and the inboard is lined with one deck encapsulant, and the outside is welded with the round steel door handle.
In preferred embodiment of the present invention, said dividing plate left and right side is respectively equipped with groove.
In preferred embodiment of the present invention, said dust discharge door can be located at a side or the both sides of ash bucket and respectively establish one.
The invention has the beneficial effects as follows: a kind of middle dividing plate that is provided with of dirt pocket that is used for economizer of the present invention; Make the air-flow of boiler exhaust gas outlet directly pass in and out from the economizer two ends; Make heat pass to water pipe as much as possible; Make full use of the hot water of its generation, have the effect of fuel savings, energy savings; The bottom is provided with dirt pocket and dust discharge door, can in time clear up the dust in the tail gas, keeps the unimpeded of boiler economizer, has prolonged the service life of economizer and dirt pocket.
Description of drawings
Fig. 1 is the perspective view that the present invention is used for dirt pocket one preferred embodiment of economizer;
The mark of each parts is following in the accompanying drawing: 1, economizer, 2, dirt pocket, 21, ash bucket, 22, dividing plate, 23, door-plate, 24, the dust discharge door, 221, reinforcement, 231, bolt, 232, nut.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1; The dirt pocket 2 that the present invention is used for economizer comprises: ash bucket 21, dividing plate 22, door-plate 23 and dust discharge door 24, ash bucket 21 are welded on economizer 1 body downside, and door-plate 23 is fixing with dust discharge door 24 through bolt 231 and nut 232; Door-plate 23 all is provided with screw hole in the upper and lower part; The inboard is lined with one deck encapsulant, makes to be connected closely between door-plate and the dust discharge door, and the outside is welded with the round steel door handle.
Be different from prior art; Dirt pocket 2 centres that the present invention is used for economizer are provided with a dividing plate 22, can effectively control flue gas stream and from economizer 1, pass through, and have well guaranteed to carry out between flue gas and the cold water sufficient heat exchange; And dirt pocket 2 is in time cleared up the dust in the tail gas; Keep the unimpeded of boiler economizer 1, prolonged 1 service life of economizer, have the effect of fuel savings, energy savings.
The present invention is used for the dirt pocket operation principle of economizer: the water inlet of economizer 1 receives and injects the cold water of coming in, and simultaneously, a termination of economizer 1 is received the dust-laden high-temperature flue gas in the boiler; The dust-laden high-temperature flue gas gets in the economizer 1 and fully contacts with economizer 1 interior water pipe; Make flue gas and cold water carry out sufficient heat exchange, when flue gas in the economizer 1 when temperature dropped to a certain extent, deduster 2 receives the dust of adhering on economizer 1 inwalls and the water pipe; Dust is discharged through dust discharge door 24; Simultaneously, the delivery port of economizer 1 is discharged hot water, when dust too much accumulates in the economizer 1; Can inject a large amount of Compressed Gas for 24 mouthfuls from the dust discharge door, remove the dust in the economizer 1.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
