Abstract

The utility model discloses an energy-saving environmental-friendly boiler, which belongs to the technical field of boiler design and manufacture. The upper part in a boiler body is provided with a heat pipe group; a hot air cabin is provided with a front smoke air guide sleeve; the other side of the heat pipe group is provided with a rear smoke air guide sleeve; the middle of a hearth is provided with an upper grate pipe and a lower grate pipe; and a superconductivity warm-air pipe is provided with a secondary oxygen supply pipe and a third oxygen supply pipe. The working principle of the energy-saving environmentally-friendly boiler is that smoke generated by burning passes through a fuel layer under the action of an induced draft fan to downwards flow to enter a secondary combustion chamber and a third combustion chamber; under the condition that high-temperature combustion-supporting oxygen is provided by the oxygen supply pipes, combustible matters in the smoke can be fully burnt; then, the smoke enters the hot air cabin and the heat pipe group via a heating chamber; and the smoke flows in the roundabout state under the action of the front smoke air guide sleeve and the rear smoke air guide sleeve. According to the energy-saving environmental-friendly boiler disclosed by the utility model, the emission amount of harmful gas is reduced due to thorough combustion. Because the front smoke air guide sleeve and the rear smoke air guide sleeve are arranged, the smoke flows in the roundabout state in the heat pipe group, the smoke residence time in the boiler body is prolonged, the heat in the smoke is fully utilized, and the fuel energy consumption is lowered.

Description

Energy-saving, environmental protection boiler

Technical field

This uses design and the manufacturing technology field of novel genus boiler.

Background technology

Now being used for industrial production and domestic heating boiler, is to be made of water jacket, burner hearth, smoke discharging pipe.The heat that burning produces heats the water in the water jacket for it.The flue gas that burning produces directly is discharged in the atmosphere.The shortcoming of this boiler is that Fuel Consumption is large, the thermal efficiency is low, and a large amount of combustibles namely are not discharged before burned, and not only contaminated environment has seriously been wasted again a large amount of energy.

Summary of the invention

For above-mentioned situation, the purpose of this utility model provides a kind of thermal efficiency height, quick heating and pollutant discharge amount circlet guarantor type boiler, solves the problem that existing equipment exists.

The utility model for the technical scheme that solution the said equipment existing problems adopt is: the top in body of heater is with heat pipe heat.Be burner hearth in the bottom of heat pipe heat.Side in heat pipe heat has a hot blast storehouse.On the hot blast storehouse with front fume flow guiding cover, on the opposite side of heat pipe heat with rear fume flow guiding cover.On front hot blast kuppe with the petticoat pipe cleaning door.One front fire door is arranged in the bottom of petticoat pipe cleaning door.In the both sides of front fire door with the heat superconducting airduct, on front fire door with the hot blast injection hole.At the pars intermedia of burner hearth with the upper fire-grating pipe, in the bottom of upper fire-grating pipe with the lower fire grating pipe.It is secondary combustion chamber between upper and lower furnace grate tube.Be three combustion chambers in the following space of lower fire grating pipe.In the bottom of front fire door shoot door on is arranged.In the bottom of upper shoot door shoot door is once arranged.Sidepiece at body of heater has an air-introduced machine, and air-introduced machine connects a smoke exhaust pipe.At the smoke exhaust pipe root with discharge closure.On smoke exhaust pipe with volume control damper.On the heat superconducting airduct with secondary oxygen supplying tube and three oxygen supplying tubes.Two oxygen supplying tubes go deep into respectively secondary combustion chamber and three combustion chambers.There is a rear fire door body of heater back of fire door before corresponding.On a side of combustion chamber, with heating clamber, a combustion chamber partition wall is arranged between heating clamber and combustion chamber.At the top of body of heater one outlet pipe is arranged.In the bottom of body of heater one water inlet is arranged.The utility model can be used for industry and civil heating, is mainly used in sea-farming, is seawater intensification firing equipment.Its operation principle is: take air-introduced machine as power, with air intake heat superconducting airduct, hot blast enters burner hearth by injection hole and fire door behind the burner hearth high-temperature heating, provides high temperature oxygen combustion-supporting material burning.Under the air-introduced machine effect, the flue gas that burning produces passes fuel bed and flows downward and enter secondary combustion chamber, the high temperature oxygen that secondary combustion chamber fuel provides at the secondary oxygen supplying tube combustion-supporting lower, and fuel bed acutely burns, and temperature can reach more than 1200 ℃.At this moment, the combustible species in the fuel is separated in fuel, simultaneously burnedly falls.Then flue gas is inhaled into the combustion chamber three times under the air-introduced machine suction function, provide in the combustion-supporting high temperature oxygen situation at three oxygen supplying tubes, fuel combustion is more violent, so that the most combustible species in fuel and the flue gas such as sulfur dioxide, carbon dioxide, carbon monoxide and hydrocarbon etc. can both fully be burnt.Then flue gas is heated the water in the water pipe by air-introduced machine suction heating clamber.Then flue gas enters the hot blast storehouse, enters heat pipe heat from the hot blast storehouse again, and the water in the water jacket is heated.Flue gas in heat pipe heat is circuitous state and flows under the effect of front fume flow guiding cover and rear fume flow guiding cover at this moment, enters air-introduced machine through discharge closure again and discharges.The utility model so that the combustible in fuel and the flue gas is fully burned, has improved the thermal efficiency because with secondary oxygen supplying tube and three oxygen supplying tubes greatly in three combustion chambers, reduced harmful gas emission.Because with front fume flow guiding cover and rear fume flow guiding cover, so that flue gas is circuitous flow regime in heat pipe heat, prolonged the time of staying of flue gas in body of heater again, the heat in the flue gas is fully used.Reduced the consumption of fuel.The utility model is simple in structure, and is reasonable in design.Our experiments show that effect is very good.
