Abstract

The utility model discloses a soot-free household energy-saving boiler that pertains to heat supply furnace. CN 2702233Y discloses a household energy-saving boiler that adopts three layer fire guide plate to make the smoke flow repeatedly up and down and to exchange heat energy for better heat efficiency. However, the utilization rate of the heat energy is insufficient and the smoke pollution problem is not completely solved; the utility model consists of a furnace, a hearth, a water jacket, a smoke channel and a cone shape fire guide plate, a round fire guide plate and a reverse fire guide plate that are communicated with the water jacket and have a flame channel to the hearth. The middle part of the reverse fire guide plate is communicated with the smoke channel and the reverse fire guide pipe is arranged along the circumference of the reverse fire guide plate. The smoke channel is connected into the smoke and dust separation room that contains water by smoke pipes, the smoke is led to the lower part of the boiler by the blower through a twice smoke pipe. The utility model has the advantages of simple structure, large heating area, fully utilization of the heat energy, high efficiency and soot free.

Description

No flue dust domestic energy-saving boiler

Technical field

The utility model belongs to the heat supply stove, relates to a kind of family expenses vertical fire coal boiler.

Background technology

At present, the most of regional employed vertical fire coal boiler of China generally comprises the heat carrier-fire tube that is provided with in body of heater, burner hearth, water jacket, flue and the burner hearth.As CN2409448Y disclosed " vertical atmospheric energy-saving boiler ", CN2562071Y disclosed " novel vertical smoke-less power-saving boiler ", all belong to the vertical boiler of fire-tube type heat carrier.This class fire-tube type heat carrier boiler, its weak point are that the without hindrance shelves of combustion flame ground straight line rises, and not only can not fully absorb the heat of flue gas, and the flue dust that is discharged in the atmosphere are bigger.This class boiler must be set up and disperse fire tube or transverse-inserting water pipe in order to improve the thermal efficiency.

CN2702233Y discloses, and a kind of " domestic energy-saving boiler " comprises body of heater, burner hearth, water jacket, flue and being positioned at above the combustion chamber, and leave passage of flame between the burner hearth, and the conical fire guiding disk that is connected with water jacket, circular fire guiding disk, reverse fire guiding disk, oppositely the fire guiding disk middle part is communicated with flue, top is provided with reverse fuse primer along circumference, though this boiler has been taked three layers of fire guiding disk from structure, flue gas flows up and down repeatedly, make thermal power transfer abundant, obtained the thermal efficiency preferably, but heat energy utilization is desirable not enough, and the smoke contamination problem does not also thoroughly solve.

Summary of the invention

The purpose of this utility model refers to remedying above-mentioned the deficiencies in the prior art, and a kind of no flue dust domestic energy-saving boiler is provided, reasonable in design not only, and heating surface area is big, and heat energy utilization is abundant, and is energy-efficient, and do not have the flue dust discharging, is comparatively ideal domestic energy-saving boiler.

Technical problem to be solved in the utility model is realized by following technical scheme:

A kind of no flue dust domestic energy-saving boiler, comprise body of heater, burner hearth, water jacket, flue and be positioned at above the combustion chamber, and leave passage of flame between the burner hearth, and the conical fire guiding disk that is communicated with water jacket, circular fire guiding disk, reverse fire guiding disk, oppositely the fire guiding disk middle part is communicated with flue, and top is provided with reverse fuse primer along circumference.Described flue inserts by smoke pipe and is equipped with in the flue dust separation chamber of water, and flue gas is introduced the boiler bottom through the secondary smoke pipe again by blower fan.

Described flue dust separation chamber is provided with separate cavities at it more than the water surface, smoke pipe enters in the water by separate cavities, is provided with outlet flue on the smoke pipe in separate cavities, and separate cavities is communicated with the secondary smoke pipe.

Top, described flue dust separation chamber is provided with the filler, blast pipe, and the bottom is provided with sewage draining exit, and the middle part is provided with overflow pipe.

In the described flue dust separation chamber, be provided with dedusting plate more than the water surface, between smoke pipe and blast pipe, be provided with the dividing plate that inserts in the water at it.

The blast pipe of described blower fan is communicated with the secondary smoke pipe.

The utility model compared with prior art has the following advantages and remarkable result:

1, owing to three layers of fire guiding disk that are provided with different structure in burner hearth, the motion of flue gas in burner hearth is multiple curve rises, thereby the heat that can make full use of in the flue gas on the one hand heats quickening intensification, the thermal efficiency of raising boiler to the water in the fire guiding disk; Flue gas can make dust come off when running into fire guiding disk on the other hand, reduces smoke contamination.

2, owing to the part flue dust of going out from boiler flue, under the effect of air-introduced machine, enter the flue dust separation chamber through the peripheral hardware smoke pipe, dirt water mixes, or up and down by dividing plate, dust is fallen into the water, and with after air mixes, the fire bars below of introducing again in the stove burns away surplus cigarette through the secondary smoke pipe, therefore, the gas that the utility model not only discharges does not have flue dust, environmentally-friendly sanitary, and heat energy is fully utilized, and is energy-efficient.
