Abstract

The utility model provides a four-protection coal fire heating furnace, which relates to personal life safety and health, as well as energy saving and discharge reduction. The utility model is technically characterized in that: an exhaust hole is arranged on the ash chamber in the furnace, an air inlet is arranged outside the furnace, a first opening fire zone is positioned above the furnace chamber, which is composed of a water seal tough above the furnace top and a flame holding drum; the flame holding drum is fastened in the water seal trough to seal the whole furnace body and prevent CO poisoning and pollution of indoor climate. A second open fire zone is arranged below the furnace chamber and is composed of external and internal walls of the furnace chamber. The chimney is moved downward and positioned at the bottom of the furnace chamber, to prevent high temperature flue gas from being directly pumped by the chimney. By arranging the first and second open fire zones and moving the chimney downward, the first heating (super hot) of the flame holding drum, the second heating (scalding) of the furnace chamber and the third heating (touchable) of the chimney can be realized. The area of smoke prevention and dust control can amount up to 7170cm<2>, which is tripled above and below the 1700cm<2> of the existing coal furnace. The utility model is also superior to the existing coal furnace in improving thermal efficiency of the furnace and eliminating smoke and dust.

Description

Four anti-coal fire warming stoves

Affiliated technical control territory:

The utility model relates to people's life security and health, relates to four anti-coal fire warming stoves of energy-saving and emission-reduction.

Background technology:

By furnace chamber, burner hearth, stone or metal plate for standing a stove on as a precaution against fire, furnace bottom, fire grate, formed for pan burner mouth, chimney, but there is certain shortcoming in present coal fire stove:

1, exhaust performance is bad.From the fire door air inlet, entering chimney by burner hearth is single channel, when banking up a fire, the burner hearth air is obstructed, a large amount of carbon monoxide of generation, because of there is the fire lid top,, cumulative from the downward adverse current of fire grate in grey chamber to grey chamber, top stuffiness and can only be from grey chamber air-leak section to external diffusion, stitch to external diffusion, thereby cause anthracemia from roof ring, lid simultaneously.

2, the burner hearth crater has only 100mm from the high 50mm in stone or metal plate for standing a stove on as a precaution against fire top from chimney, and naked light district area only has 1700cm ²Up and down, and chimney is in stone or metal plate for standing a stove on as a precaution against fire, and high-temperature flue gas goes out burner hearth inertia force and adds draft and taken away by chimney rapidly, not only lose to waste energy, and the severe contamination atmosphere.

3, existing coal fire stove deashing, when rousing fire,, pollute indoor environment from fire door and top circle, the lid outside flying dust of seam and diffusion pernicious gas and burning peculiar smell.

Summary of the invention:

For overcoming the life security that there is the harm people in existing coal fire stove, severe contamination is indoor, the outdoor environment problem.The novel coal fire warming stove that the utility model provides a kind of can not only be prevented anthracemia, prevent loss and waste energy, prevent the severe contamination atmosphere, prevent to pollute indoor environment.

The technical scheme in the invention for solving the technical problem is: four anti-coal fire warming stoves are made up of furnace chamber, fire door, furnace bottom, fire grate, burner hearth, stone or metal plate for standing a stove on as a precaution against fire, chimney.In top, grey chamber a steam vent is set, the naked light district is provided with an air admission hole outside body of heater, with the wide 60mm of 2mm iron plate, a high 270mm steam vent, a high 370mm air admission hole, respectively make with the furnace chamber arc, each outwards pounds out the limit of 15mm both sides, steam vent is sitting on the burner hearth base and the furnace chamber welding, air admission hole is sitting on the furnace bottom, and by burner hearth base and furnace chamber welding, two all suitable for reading flat with furnace chamber, the steam vent position hits exactly at fire door, and the air admission hole position is chimney left side (furnace bottom and burner hearth base are accomplished fluently eye in advance).Stove top is provided with the first naked light district, is made up of fire-suppressing tube and water sealed tank, and heating surface area reaches 2735cm ²Fire-suppressing tube is used 1.5mm iron plate, diameter 280mm, and high 200mm binds with 2mm iron plate; The furnace chamber outer wall is provided with water sealed tank, 1.5mm iron plate is used at the end, interior diameter 265mm, overall diameter 350 annular iron rings, pack into and return the welding of 35mm place under the cavity top, groove nation is welded in (35mm in the tank, 35mm is for stone or metal plate for standing a stove on as a precaution against fire on the tank) with the high 70mm of 1.5mm iron plate diameter 350mm at the end, uses the 15mm iron pipe at the bottom of the tank, long 100mm, bottom land top 30mm is than the low 5mm of furnace chamber, and 70mm is welded on the bottom land under the groove, the excessive or water expansion spilling water in furnace chamber of Fang Jiashui.Fire-suppressing tube is buckled in the water sealed tank, has sealed whole body of heater; Fire door is provided with dustproof ash bucket, on existing ash bucket basis, widens the limit (following 10mm) of 20mm around the back nation, the middle eye that bores 7mm, and ash bucket injects fire door and blocks four limits when rousing fire, prevents that the dust houseful from flying; Burner hearth separates with furnace chamber, and the second naked light district is set, form by hearth outer wall, furnace chamber inwall and burner hearth base, and wide on every side 25mm, high 270mm, heating surface area reaches 2664cm ²(containing fin), hearth outer wall 1772cm ², the smoke abatement and dust control area reaches 7170cm ²Burner hearth is (desirable the putting when clearing up the second naked light district heating surface and chimney) of living, and uses 2mm iron plate, the high 270mm of diameter 209mm, and cylinder iron fire grate is filled in welding from end mouth, rock wool heat-preservation around the tile, cylinder iron fire door is put in the tube and is fixed with refractory cement.Burner hearth and furnace chamber are flat, burner hearth bottom is provided with the burner hearth base, and base is made interior diameter 150mm overall diameter 259mm annular iron ring with 3mm iron plate, the iron ring of a high 10mm diameter 210mm of weldering at the end, burner hearth is sitting in stable base in the circle, and base is welded on the furnace chamber inwall then; 12 fins (steam vent, air admission hole are for two) are arranged therebetween, use 2mm iron plate, the long 150mm of wide 24mm welds downwards from cavity top, and burner hearth and fin are gapped, divide fixedly upper furnace of triangle with 3 iron plate bars; Chimney moves down, and with wryneck of 3mm iron plate weldering, is welded on the furnace chamber outer wall, and is flat at the bottom of position and the burner hearth.

Effect of the present utility model is:

Realize the gas benign cycle in the body of heater, furnace roof has sealed whole body of heater with fire-suppressing tube and tank, has prevented anthracemia and has purified the air of a room indoor.The steam that the while water sealed tank comes up outside fire-suppressing tube plays the humidifier effect, enters the favourable smoke abatement and dust control of steam in the fire-suppressing tube.Utility model increases by the first naked light district, the second naked light district, and chimney is arranged on the bottom, has realized fire-suppressing tube first heat (special heat) furnace chamber outer wall second heat (scalding one's hand) chimney the 3rd heat (hand can be touched).The smoke abatement and dust control area reaches 7170cm ²Than existing coal stove 1700cm ²Increase more than three times, solved inertia force simultaneously and added draft, fast high-temperature flue gas is entered atmosphere, contaminated environment.
