Abstract

The utility model discloses an energy-saving and environmental-protection boiler. The utility model mainly comprises a heat exchange chamber, a burning chamber, an ash slag chamber, etc. The interior of the heat exchange chamber is respectively provided with an outer water chamber, an outer fire chamber, a middle water chamber, a middle fire chamber, an inner water chamber and an inner fire chamber from inner to outer. The outer water chamber, the middle water chamber and the inner water chamber are respectively communicated through an upper water tank. The upper water tank is provided with a water outlet. The lower parts of the outer water chamber, the middle water chamber and the inner water chamber respectively heat the water of each water layer corresponding to the outer fire chamber, the middle fire chamber and the inner fire chamber through fire smoke which is come out of a communication burning chamber through connection water pipes. As the structure is used, the structure is simple, the open fire and the high-temperature fume are fully utilized, and the heating surface is enlarged. A return-stroke device is used, the time of the high-temperature fume remained in the furnace body is lengthened, the heat efficiency is high, the powder dust is conveniently cleaned and the pollution is not provided.

Description

A kind of energy-saving, environmental protection boiler

Technical field

The utility model belongs to heating equipment, particularly relates to a kind of power economized boiler that burns coal.

Background technology

At present, coal-burning boiler is still the main heating equipment of all trades and professions, along with the growing tension of the energy, and increasing the weight of year by year of environmental pollution, also more and more stricter to the requirement of coal-burning boiler, promptly require high energy-conservation, high efficiency, pollution-free.Yet existing boiler mostly in various degree exist that thermal energy conversion efficiency is low, waste of fuel is many, the environmental pollution important disadvantages.Chinese patent " a kind of three novel backhaul thickness pipe vertical boilers " though improved the thermal efficiency, has reduced environmental pollution, but still has complex structure, the still inadequate problem of burning.

Summary of the invention

The purpose of this utility model is exactly to have at existing coal-burning boiler that burning is insufficient, the thermal efficiency is low, heavy-polluted problem, and a kind of heating surface of design is big, and heated time is long, and fuel can fully burn, thermal efficiency height, free of contamination energy-saving, environmental protection boiler.

The purpose of this utility model is to realize like this, it mainly comprises heat-exchanging chamber 1, combustion chamber 2, parts such as cinder chamber 3, the top of combustion chamber 2 is heat-exchanging chambers 1, the bottom is a cinder chamber 3, the inside of heat-exchanging chamber 1 is provided with outer hydroecium 4 from outside to inside successively, outer fiery chamber 5, middle level hydroecium 6, fire chamber 7, middle level, internal layer hydroecium 8, internal layer fire chamber 9, outer, the middle level, internal layer hydroecium 4,6,8 communicate by upper water box 10 respectively, upper water box 10 is provided with delivery port 11, outward, in, the bottom of internal layer hydroecium is to communicate by connecting water pipe 16, water inlet 12 is established with outer hydroecium 4 and is linked to each other, outer, the middle level, internal layer fire chamber 5,7,9 communicate by the fireworks channel 13 that is arranged on each layer respectively, the pyrotechnics that comes out in combustion chamber 1 passes through skin successively, the middle level, internal layer fire chamber 5,7, after 9 pairs of corresponding each water layer water heating, arrive lime-ash sedimentation basin 14, a large amount of solid soots are discharged by smokestack 15 at last through post precipitation.

Because adopt said structure, the utility model is simple in structure, has made full use of naked light and high-temperature flue gas, has increased heating surface, adopt return facilities, guarantee that high-temperature flue gas is trapped in the time lengthening in the body of heater, thermal efficiency height, the dust cleaning is convenient, pollution-free.
