Description

Energy-conservation ground of fluorine kitchen range efficiently falls

Technical field

The utility model relates to a kind of ground kitchen range, relates in particular to a kind of family or public place of can be applicable to and efficiently falls energy-conservation ground of fluorine kitchen range, genus F24B1/18 class for the reduced harmful gas emission of the heating or the usefulness of cooking a meal and energy resource consumption.

Background technology

Before the utility model patent application case, it is fairly simple to be used for heating of family and public place or used its structure of underground heat cooking stove or the shape of kitchen: promptly directly dig a hole and put into finished product combustion chamber and ventilation duct and Feng Gai underground, the pernicious gas that coal-fired (as honeycomb briquette) produces in combustion process can not drain chamber outside, and directly circle round indoor.The underground heat cooking stove of this structure and shape especially can bring very big harm to human body for the fluorine-containing fire coal of burning, and the gas of band fluorine can cause osteoporosis fracture and very difficult healing easily after being inhaled into human body.The fire coal that a lot of small coal mines in China south are exploited all contains this harmful substance of fluorine in various degree, has both jeopardized health, also can pollute to environment.

Summary of the invention

Task to be solved in the utility model provides a kind of not only energy-conservation but also the harmful substance in the fluorine-containing fire coal efficiently can be fallen energy-conservation ground of fluorine kitchen range through what repeated combustion can reduce content.

For realizing above-mentioned task, the technical solution adopted in the utility model is: dig a size earlier in the flooring as required again near the melt pit of wall, this melt pit can be circular or the cubic bodily form or cuboid, at this point Keng a side is put a blast pipe in advance, with common brick or other construction material construction wall, in body of wall, stay an exhaust passage on one side by indoor wall, place combustion chamber at the body of wall central part, combustion chamber is placed on the fire bars, put cover in the outer of combustion chamber, heat-insulation layer (as pearl sand) is arranged in middle cover and combustion chamber space, between middle cover and (common brick) body of wall, put into one simultaneously and overlap greatly, form the flue gap between middle cover and the big cover.Cyclone plate is placed on the combustion chamber, at air bells cap of making of metal material (as steel plate) of the central upper portion position of (common brick) body of wall device, cover plate is arranged on air bells cap.Be with the wind lid on the blast pipe of the part that elevates above the soil.Be connected with ash bucket near on the blast pipe of combustion chamber lower end, the air that comes from blast pipe can enter combustion chamber from the top of ash bucket, and the exhaust passage is outside the loose joint communication chamber.

That adopts that as above technical scheme provides efficiently falls energy-conservation ground of fluorine kitchen range compared with prior art, and the beneficial effect of acquisition is:

1. owing on the combustion chamber cyclone plate is arranged, the gas (as fluorine) that has that the fire coal that burns from combustion chamber produces can flow and can carry out repeated combustion to pernicious gas last time at cyclone plate, reduce the discharge of harmful gases amount, pernicious gas can be discharged indoor from the exhaust passage, does not pollute indoor;

2. improve in the combustion chamber coal-fired combustion rate 20～30%, reduced in the slag can coal-fired quantity, remarkable energy saving effect is arranged.

3. can enlarge the scope of application of fuel, be particularly suitable for the family and the public place of agricultural and remote mountain areas;

4. can be made into integral product, installation, easy to carry;

5. can reach more than 10 years service life.

Description of drawings

Accompanying drawing is a structure cross-sectional schematic of efficiently falling energy-conservation ground of fluorine kitchen range described in the utility model, also is specification digest accompanying drawing of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

As shown in drawings, 1 is ash bucket, and 2 is blast pipe, and 3 are the wind lid, and 4 be cover plate, and 4 ' be that air bells cap, 5 is combustion chamber, 5 ' be middle cover, 5 " be to overlap greatly, 6 is heat-insulation layer, and 8 is the exhaust passage, and 9 is body of wall, and 10 is loose joint, and 11 is to cheat body, and 12 is cyclone plate.In body of wall 9 or hole body 11 in the blast pipe 2 installation melt pits of metal material or nonmetallic materials (as steel pipe or pipe of cement) making, wind lid 3 is arranged on one the blast pipe 2 of basseting, connect ash bucket 1 on the other end of blast pipe 2, the upper surface of ash bucket 1 can lead directly to combustion chamber 5.Described body of wall 9 can be built by laying bricks or stones with common brick or other construction material, and hole body 11 can be selected the concrete mortar cast for use.Be placed with combustion chamber 5 in the centre of body of wall 9, described combustion chamber 5 is to make of refractory material can buy product through the market that calcining forms, the interior end at combustion chamber 5 is fixed with fire bars, place in the combustion chamber 5 and remain to be burnt or spent fire coal (as honeycomb briquette), overlap 5 among the outer Zhou Fangyou of combustion chamber 5 ', combustion chamber 5 and middle cover 5 ' between heat-insulation layer 6 is arranged, heat-insulation layer 6 can adopt materials such as pearl sand, middle cover 5 ' and body of wall 9 between big cover 5 is arranged "; middle cover 5 ' and big cover 5 " between form flue gap 7, described in cover 5 ' with overlap 5 greatly and " all can make of refractory material.Be manufactured with exhaust passage 8 at the body of wall 9 near indoor wall with body 11 places, hole, exhaust passage 8 can be pre-buried with steel pipe or plastic tube.Exhaust passage 8 is logical outdoor through loose joint 10, and 7 can discharge coal combustion exhaust outdoor with exhaust passage 8 through the flue gap.Cyclone plate 12 be placed in combustion chamber 5 or middle cover 5 ' on.Have in middle part, body of wall 9 upper end air bells cap 4 ', air bells cap 4 ' the lower port external diameter be a bit larger tham the external diameter of combustion chamber 5.Cover plate 4 available metal materials are made, it be placed on air bells cap 4 ' upper port, cover plate 4 and air bells cap 4 ' upper port shape identical (as polygons such as circle, squares).

During use, energy-conservation ground of fluorine kitchen range efficiently falls according to making shown in the accompanying drawing, open wind lid 3, make outside air enter blast pipe 2 and enter combustion chamber 5 again through ash flue bucket 1, to burn or fire coal (as honeycomb briquette) to be burnt is put into combustion chamber 5 successively, the coal-fired gas (as fluorine-containing pernicious gas) that is produced in burning flows from bottom to top and is introduced in the cyclone plate 12 in the combustion chamber 5, owing in the cyclone plate 12 the polylith whirlwind sheet is housed evenly, the pernicious gas that is produced mobile mixing with the flare that produces from combustion chamber 5 in cyclone plate 12 carried out repeated combustion to fluorine-containing pernicious gas, improves coal-fired efficiency of combustion.The coal-fired hot gas that in combustion process, produces import into air bells cap 4 ' and cover plate 4 on, not only heated body of wall 9 but also roasting hot cover plate 4, import indoor lifting indoor temperature into by cover plate 4 and body of wall 9, reach the purpose of heating.The coal-fired few part heat that in combustion process, produces and without the waste gas that burn through flue gap 7 and exhaust passage 8 discharge, can not endanger the indoor human body generation.After long-term the use, the coal-fired waste residue that produces can be fallen in the ash bucket 1 automatically in the combustion chamber 5, pulls out to be reentered into after ash bucket 1 is handled waste residue.Open cover plate 4, the fire coal that has burnt in the combustion chamber 5 can be taken out and be reentered into unburned fire coal.Burning degree coal-fired in the combustion chamber 5 can be by regulating from wind lid 3 air capacities that enter blast pipe 2.
