Abstract
The utility model discloses an energy-saving dust collector, which comprises a casing with an interlayer. A smoke inlet and an ash cleaning outlet are arranged at the top of the casing, a hot air outlet is arranged on one side of the upper portion of the casing, an ash discharge outlet is arranged at the bottom of the casing, a smoke outlet is arranged on one side of the bottom of the casing, a heat exchange pipe is arranged in the casing, two ends of the heat exchange pipe are communicated to the interlayer of the casing, an upper air partition layer and a lower air partition layer are arranged in the interlayer of the casing in a staggered manner so as to divide the interlayer into three air travels, and a cool air inlet is arranged on one side of the lower portion of the casing and disposed below the lower air partition layer. Compared with the prior art, the energy-saving dust collector has both functions of dust removal and heat exchange, and solves the technical problem of failure in combination of afterheat recovery and dust removal in the prior art. Cool air can be supplied for boilers after being subjected to heat exchange, and accordingly the dust collector is energy-saving and environment-friendly.
Description
Technical field the utility model belongs to the cleaner technical field, relates to a kind of energy-saving dust remover.
Background technology is present; Air preheater is widely used in the flue gas afterbody of industrial products such as various stoves, kiln; The purpose that reaches waste heat recovery plays the effect of energy savings again; Owing to contain amounts of dust in the flue gas, necessary again supporting installation deduster behind the flue gas afterbody installation air preheater of a lot of industrial products is to reach the purpose that reduces dust in flue gas content protection environment.A lot of occasions require can recovery waste heat again can dedusting, if a kind of equipment can have this two kinds of functions simultaneously, make so, transport, installation, management costs will reduce greatly and operating efficiency also can improve.
The purpose of summary of the invention the utility model is to solve the technical problem that prior art exists waste heat recovery and dedusting not to take into account simultaneously; A kind of energy-saving dust remover that can carry out waste heat recovery again can dedusting is provided, thereby increases work efficiency, reduce manufacturing, transportation, installation, management cost.
The utility model energy-saving dust remover, it comprises sandwich shell, and the top of housing is provided with into mouth and cleaning door, and top one side of housing is provided with hot air outlet, and the bottom of housing is provided with ash port, and a side of housing bottom is provided with outlet flue; Be provided with heat exchanger tube in the said housing, the two ends of heat exchanger tube are communicated with the interlayer of housing, and interlocking in the interlayer of said housing is provided with upper and lower two-layer air baffle, and said upper and lower two-layer air baffle is divided into three air strokes with interlayer; One side of lower housing portion is provided with inlet of cold air, and said inlet of cold air is positioned at the below of lower floor's air baffle.
The utility model compared with prior art has two kinds of effects of dust-collecting and heat exchanging, has solved the technical problem that prior art exists waste heat recovery and dedusting not to take into account simultaneously.Cold wind is through heat exchange, can supply with boiler and use, not only energy-conservation but also environmental protection.
Appended drawings is the utility model structural representation.
Among the figure 1, hot air outlet 2, advance mouth 3, cleaning door 4, sandwich shell 5, air baffle 6, inlet of cold air 7, heat exchanger tube 8, outlet flue 9, ash port.
The specific embodiment is with reference to accompanying drawing; It comprises sandwich shell 4 the utility model, and the top of housing 4 is provided with into mouth 2 and cleaning door 3, and top one side of housing 4 is provided with hot air outlet 1; The bottom of housing 4 is provided with ash port 9, and a side of housing bottom is provided with outlet flue 8; Be provided with heat exchanger tube 7 in the housing 4, the two ends of heat exchanger tube 7 are communicated with the interlayer of housing 4, and interlocking in the interlayer of housing 4 is provided with upper and lower two-layer air baffle 5, and upper and lower two-layer air baffle 5 is divided into three air strokes with interlayer; One side of housing 4 bottoms is provided with inlet of cold air 6, and inlet of cold air 6 is positioned at the below of lower floor's air baffle 5.
The utility model is owing to arranged a considerable amount of heat exchanger tubes 7, and comparing with traditional air heat exchanger has increased heating surface area, has improved the heat exchange effect.Air baffle 5 is cut apart housing 4, makes air be divided into three strokes, has prolonged heat-exchange time; Improved the heat exchange effect; Ash port 9 is done tapered and outlet flue 8 is used, and makes the flue gas helical flow, because the flue dust in the action of centrifugal force flue gas obtains separating, further having purified flue gas once more.
The operation principle of the utility model: extraneous cold air gets into heat exchanger tubes 7 from inlet of cold air 6, heat exchanger tube 7 in pipe outside high-temperature flue gas carry out heat convection, the absorption great amount of heat.Because air baffle 5 is divided into three spaces to housing 4 inside, cold air has prolonged the heat-exchange time of cold air and high-temperature flue gas through three strokes, has improved the heat exchange effect.Air behind the absorption heat is exported from hot air outlet 1, and boiler of feeding uses.
High-temperature flue gas at first gets into housing 4 inside from advancing mouth 2 from extraneous flue, the flue cross-sectional area in the external world is far smaller than the cross-sectional area of housing 4 inside, makes the cigarette prompt drop low; The flue dust that particle is bigger drops to ash port 9 under the effect of gravity, and high-temperature flue gas receives stopping of heat exchanger tube 7, and part kinetic energy is transformed into heat energy; Velocity of flue gas further reduces; Most of flue dust gravitate is deposited to ash port 9, and this moment high-temperature flue gas with the cold air convection heat exchange of heat exchanger tube 7 inside, most of heat is taken away by air and is recycled; Reduce energy waste, reduced flue-gas temperature; Advance people's ash port 9 first halves through heat exchanger tube 7 back flue gases, ash port 9 is tapered, makes the flue gas helical flow, and under the effect of centrifugal force and gravity, the flue dust in the flue gas obtains separating, and flue gas further is purified, and clean flue gas is discharged from outlet flue 8.
This novel energy-conserving deduster; When absorbing heat, remove flue dust, conserve energy and protection environment are different from traditional a kind of equipment and can only play a kind of effect; Improved operating efficiency; Alleviated labour intensity, reduced manufacturing, transportation, installation, management costs, for society has practiced thrift a large amount of resources.
