CN2591509Y - Labyrinth type dust-removal fireproof civil energy-saving boiler - Google Patents

Abstract

The utility model discloses a labyrinth type dust-removal fireproof civil energy-saving boiler, which is a sandwich type hot water boiler used an outer wall 1 and an inner wall 2 as a body. The utility model is characterized in that a plurality of labyrinth type baffle plates which are arranged in a staggered form are arranged in a flue. Thus the flue stroke of flue gases is lengthened and the heating area is increased. In order to more effectively utilize heat energy, at least a non-ferrous metal spiral pipe 11 is spirally arranged along the inner wall 2 from bottom to top. The top end of the boiler is provided with a fireproof cover 5 and a fireproof net 8. Coal burning dust can not outwards leak. Therefore, the utility model has dust-removal and fireproof functions. A grate 15 which can be swung can make boiler dust automatically fall into a dust storage chamber 25 for reducing dust pollution for environment under the condition of closing a dust door. The utility model is a civil boiler with environmental protection and energy saving.

Description

The labyrinth type dirt fire prevention domestic energy-saving boiler that disappears

The utility model relates to a kind of civil boiler, particularly a kind of have eliminate flue dust and prevent the power economized boiler that Mars splashes.

Live in woods pastoral area, town and country, still do not have the single seat building of collective's heating and the one-storey house of single household, progressively by heating installation replaced by stove, the wall with flues heating mode of houseful flying dust winter, and the civil boiler that arises at the historic moment spreads all over the various places, town and country.Because the still unformed standard of country, the boiler that various places produce is very different, and some is not energy-conservation, and Dark smoke billows, and heat is imitated low, wastes energy, and very serious to air pollution, strong convective weather Mars splashes, and brings hidden danger for the fire safety in agricultural pastoral area.Use which type of civilian heating boiler is the important thing that relevant department should get involved for a long time actually, also is one of important topic that is worth research.

The purpose of this utility model, just provide a kind of have eliminate the smoke safely fire-proof function, can make full use of heat energy, interior dress helix tube, the labyrinth type dirt fire prevention domestic energy-saving boiler that disappears.

For achieving the above object, the technical solution of the utility model is: boiler inner wall is adorned a plurality of staggered labyrinths plate washer in order to prolong flue length, at least one nonferrous metal tube of helical arrangement increases heating surface area from the bottom to top, there is the dust hood that disappears on the flue top, there is the palisade flame screen at the flue outlet place, and for utilizing heat energy more fully, a concave bottom water tank is arranged at the dust hood top that disappears, for hot water for washing, the fire grate in the stove under the grate is the automatic ash-removing stove row of swaying type.

Employing the utility model has the advantages that:

1. by installing a plurality of flue plate washers and helix tube additional, increase heating surface area, dwindle body of heater, reduce and manufacture material and daily required fuel, reach energy-conservation purpose.

2. because the dust hood of disappearing flame screen is arranged, eliminate coal-fired pollution and disaster hidden-trouble, belong to environmentally friendly machine air.

3. the swaying type fire grate is arranged, close ash door ashes and fall automatically to spattering the favorable environment health outward.

4. China is to be the big country of main fuel with the coal, and eliminating the coal smoke contamination is the major issue that part is benefited the nation and the people, and the utility model adapts to wide, and market potential is big, and promotional value is arranged.

Below in conjunction with drawings and Examples, be described in further detail.

Fig. 1, boiler shown in Fig. 2 is the sandwich-type hot-water boiler, constitute body of heater by outer wall 1 and inwall 2, inwall 2 has a plurality of sandwich-type plate washers 3, be staggered with labyrinth type, fixedly be communicated with inwall 2 welding respectively, its effect not only can make flue stroke lengthening but also the body of heater heating surface area is strengthened, for further increasing heating surface area, has a non-ferrous metal helix tube 11 in the flue at least, fixedly be communicated with boiler inner wall 2 welding by helix tube starting point 12, the fixing connection of outlet 13 welding along inwall 2 helical arrangement to heat supply from bottom to top, flue 4 peripheries suitable for reading are that dust hood 5 its loam cakes that disappear are concave bottom water tanks 9, the water tank outer lower portion has a discharging valve 10, dust hood 5 sidewall exhanst gas outlets 7 places that disappear establish a flame screen 8, between boiler bottom and the Dust Storage Room 25 just like Fig. 5,6,7, fire grate shown in 8, this fire grate are by fire grate axle 17, with the swaying type fire grate 15 of fire-grating frame 18 and frame hole 19 compositions.

During the stove fuel combustion, flue gas rises to flue 4 places suitable for reading along inwall 2 through multiple tracks labyrinth type interlayer baffle plate 13, chance disappears at the round end of concave bottom water tank 9 on dust hood 5 tops, because of flue outlet 7 is lower than the round end, flue gas must be as Fig. 1. and the periphery that changes at the dust hood 5 that disappears down shown in the middle arrow produces vortex, form a quiescent centre, dust in flue gas is fallen in the accumulation area 6, play the dirt effect that disappears, it is big that the strong convective weather chimney is taken out strength, discharges chimney for preventing flue dust for fire, specially establishes a flame screen 8 at flue outlet 7 places, in order to block unlikely the leaking of flue dust of generation fire once more, play anti-fire action.

Between boiler casing 1 and the inwall 2 is thermophore---water 27, heating system is supplied with by heat supply outlet 13 in the heating back, get back to boiler by return pipe 14 after the heat release, when fuel combustion is emitted heat when becoming ashes, must remove, otherwise influence the burning of fuel, because the calorific value of every generation 1000 kilocalories needs to enter 105 cubic metres air through fire grate, artificial deashing is being opened the ash door and is being caused dust to flash, contaminated environment, fire grate are closed ash door 26 16 outside body of heater during deashing, shake fire grate 16, ashes fall into Dust Storage Room 25 interior dusts automatically and can not leak.

A plurality of labyrinths plate washer is arranged in the boiler flue, can accumulate a large amount of dust and cigarette stain, for ease of removing the maintenance that reaches baffle plate, an ad hoc cleaning maintenance interlayer door 20 shown in Fig. 3,4 flexibly connects with furnace body outer wall 1, and the outer wall of door has last interface 23 to be communicated with heat supply outlet 13 through flexible pipe 24, lower interface 21 is communicated with furnace body outer wall lower interface 28 through flexible pipe 22, this cleaning access door 20 has been arranged, the heat utilization efficiency of boiler is further improved, and cleaning property and maintenanceability.
