Abstract

The utility model discloses a smoke preventing dust control heat pipe type energy saving boiler which is characterized in that a set of heat pipe type secondary boiler 6 is arranged in the main boiler of a water tube boiler. The upper part of the inner wall is provided with at least three interlayer backfolding baffle plates 12. The heating area is increased and the purpose of conservation of energy is obtained. The lower part of the boiler body is provided with a basin shape fire grate 11 which can make the fuel be burnt normally without any air blast or draught fan. The upper part of the smoke channel exit 13 is provided with a pyramidal flow guiding body 19 and a dust removal cover 21, which can make the boiler reduce the discharge of the smoke and prevent the atmosphere from being polluted by the smoke.

Description

Smoke abatement and dust control heat pipe-type power economized boiler

Affiliated technical field: the utility model relates to a kind of boiler, particularly has the tubular boiler of smoke abatement and dust control function.

Background technology: China is coal-fired big country, and the civil heating boiler is all based on coal, and the most flue dust of coal-burning boiler is big; environmental pollution is serious, how to improve boiler hot and imitates energy savings, reduces soot emissions; the protection atmosphere is few contaminated, is a big problem that is worth people to inquire into.

Summary of the invention: the purpose of this utility model just provides a kind of heat and imitates height, the heat pipe-type power economized boiler with smoke abatement and dust control function.

For achieving the above object, the technical solution of the utility model is: install a cover heat pipe formula stove in water-tube boiler parent stove additional; The parent stove is upright sandwich-type, many of its inwalls are vertically arranged the water pipe that is interconnected, sub-stove also is the many heat pipes that vertically are arranged in centre in the parent stove, every heat pipe periphery is all overlapped with water pipe and is communicated with female stove, the stove upper inside wall has at least three interlayer baffle plates, labyrinth type is arranged, strengthen heating surface area, stop the flue dust ascension, reduce smoke contamination, for the fire grate that strengthens the ventilation combustion chamber is a peviform, and around basin, be provided with vertical bar shape slotted hole, the upper of furnace body smoke outlet one cone is arranged and the dust hood that disappears in order to eliminate the pollution of flue dust to atmosphere.

Employing the utility model has the advantages that: 1. give full play to the strong point that the heat pipe conduction is fast, the heat effect is high, reach energy-conservation purpose, 2. peviform furnace grate ventilation amount is big, exempt air blast, air-introduced machine noise, make the environment peace and quiet, the dust hood that 3. disappears reduces smoke discharge amount, reaches the environmental protection purpose.

Description of drawings: the utility model is further described below in conjunction with drawings and Examples.

Fig. 1 is the outward appearance front view of the utility model smoke abatement and dust control heat pipe-type power economized boiler,

Fig. 2 is the A-A face cutaway view of Fig. 1, and Fig. 3 is the B-B face cutaway view of Fig. 1,

Fig. 4 is the cutaway view of the utility model peviform fire grate.

The specific embodiment:

Fig. 1 boiler shown in Figure 3 is by furnace body outer wall 1, inwall 2, the upright clevis layer water pipe parent stove that water pipe 3 constitutes reaches by heat pipe 4, sub-stove 6 common combinations that jacket pipe 5 is constituted form, inwall upper end 7, inwall lower end 8 is communicated with the two ends of water pipe 3, heat pipe 4 in the sub-stove is fixing by jacket pipe 5, jacket pipe upper end 9, lower end 10 respectively with inwall upper end 7, lower end 8 is communicated with, the tub wall of peviform fire grate 11 shown in Figure 4 has vertical bar shape air vent 18, improve wind supply quantity, favourable fuel is under condition of natural ventilation, do not establish air blast, air-introduced machine can reach normal combustion, does not have mechanical noise to make the environment peace and quiet.

The taper baffle 19 at flue outlet 13 places, when making flue gas rise to arc along outer rim 20 along it, granular flue dust falls in the dust hood 21 lower stationary districts 22 that disappear, thereby the flue dust of being discharged by chimney is minimized, and reaches the purpose of smoke abatement and dust control.

The utility model is work like this: fuel is added to peviform fire grate 11 internal combustion by fire door 17, heat rises to the plate 12 of turning back along inwall 2, water pipe 3, heat pipe 4, owing to be that labyrinth shape is staggered, the heat of several times turning back is further fully absorbed the back to flue outlet 13, discharges out of the furnace after cone disappears dirt again; Water temperature is sent into heating system by delivery port 14 after raising in the stove, gets back to heating again in the stove by water return outlet 15 after the heat release.Two cleanouts 16 are arranged at fire door 17 tops, are used to clear up cigarette stain in the stove.
