Abstract

The present invention discloses an environment protection type energy saving and normal pressure water boiler which mainly relates to a heat exchanging device. The present invention mainly comprises a bottom part and an upper part, wherein the bottom part is provided with a water inlet pipe (1), a water discharging valve (4) and a corrosion prevention water discharging hole (11), the upper part is provided with a water outlet pipe (2) and an exhaust safety valve (3). The present invention is characterized in that the boiler is a secondary combustion smoke abatement device (12) and a third combustion smoke abatement device (13), a connecting pipe (5) for two boilers is arranged on the outer part of a smoke exhaust heating body, and a combustion chamber and a smoke exhaust heating body which is connected with the combustion chamber are cuboids, wherein the smoke exhaust heating body has a three-return structure. The present invention has the advantages of secondary heating, heat efficiency enhancement and no smoke and dust exhaust, and can improve many times combustion smoke abatement of a combustion condition. Atmospheric pollution is black smoke firstly, and the black smoke is precious fuels so as to improve combustion conditions, enhance heat inefficiency, abate smoke and dust, and protect an atmospheric environment.

Description

Environment-friendly type energy-saving normal pressure water boiler

Technical field

Environment-friendly type energy-saving normal pressure water boiler belongs to heat-exchange device.

Background technology

At the northern China cold district, the warming phase is long, adopts the unification heat supply heating except that office building, Civil apartment in cities and towns, and the town and country one-storey house adopts the disposable heat boiler that is subjected to of the disposable burning of conventional cold wind mostly.Use this heating system, the subject matter of existence be the thermal efficiency low, waste energy, atmosphere pollution and surrounding enviroment.

Summary of the invention

This bright purpose is: provide a kind of second-time burning, secondary to be heated and eliminate smoke for three times, promptly save the energy, improve the thermal efficiency, do not have environmental pollution, this energy-conservation boiler has solved the drawback of prior art.

Project organization of the present invention is reasonable, by improving combustion conditions, improves the thermal efficiency, and does not have the pollution to atmospheric environment of black smoke, dust.

The specific embodiment

Below in conjunction with accompanying drawing environment-friendly type energy-saving normal pressure water boiler is described further:

This boiler is that secondary oxygenation burning smoke device 12 is set in the combustion chamber, and fire and water layer are separated, and improves ignition temperature, after the smoke eliminator preheating, fresh air becomes hot blast by the air vent on the smoke eliminator and enters the combustion chamber, produces second-time burning, is exactly the secondary oxygenation, three oxygenation burning smoke devices 13, also be the principle of second-time burning, just three oxygenations produce burning again with the black smoke that does not once have burning, can produce blue fire, best results with forced ventilation.

This stove is three to return heated body, with heat absorption, there is not heat-energy losses, and the temperature difference exchange of being heated by secondary removes dust with dust separation by secondary ash door 20, and the condensed water that the temperature difference that can utilize secondary to be heated produces extracts coal tar, coal tar reclaims by secondary ash door 20, because coal tar is fine chemical material, be again senior auximone, this boiler has played the effect of resource reutilization again.

Second-time burning smoke elimination of the present invention three burning smokes, secondaries are subjected to a fiery twin furnace of thermal recovery, do not lose heat energy, and back stove pushes away forehearth, improves the thermal efficiency, does not have the pollution of black smoke dust to atmosphere.
