Abstract
The utility model discloses a smoke elimination energy saving device of a boiler. The smoke elimination energy saving device comprises a draught fan, and a combustion chamber is disposed on the lower portion in a shell of the smoke elimination energy saving device. Two ends of a flue gas pipe are respectively communicated with flue gas exhaust pipes of the combustion chamber and the boiler. An air inlet pipe is disposed on the upper portion of the combustion chamber. A fire grate is disposed on the lower end of the combustion chamber. A feeding mouth is disposed on the wall of the combustion chamber above the fire grate. An air inlet and an air outlet of the draught fan are respectively communicated with the air inlet pipe and an ash bin below the fire grate. A water tank is arranged on the upper portion in the shell of the smoke elimination energy saving device. A fire tube is disposed in the water tank. A lower end mouth of the fire tube is communicated with the combustion chamber. An upper end mouth of the fire tube is communicated with a flue gas tank above the water tank. The flue gas tank is provided with a flue gas pipe communicated with the air inlet pipe. An inlet of the flue gas pipe communicated with a flue gas exhaust mouth of the boiler is tangent to the inner wall of the combustion chamber. The smoke elimination energy saving device is applied to energy conservation and dust extraction of the boiler.
Description
Technical field:
The utility model relates to the fume removing and energy saving device of a kind of burning and dedusting technology, particularly a kind of boiler.
Background technology:
Environmental protection now requires increasingly high to the fume emission of boiler; But still there be the influence of fume emission to environment in present boiler, and simultaneously, the temperature of the flue gas that boiler gave off is higher; And contain unburnt material such as CO etc. in the flue gas more or less, wasted the energy.
Summary of the invention:
The utility model purpose provides and does not a kind ofly waste energy and do not pollute or the fume removing and energy saving device of a kind of boiler that contaminated environment is extremely slight.
Realize that the utility model purpose technical scheme is; Comprise air-introduced machine, it is characterized in that: the bottom in the fume removing and energy saving device housing is provided with the combustion chamber, and the two ends of fume pipe are communicated with the smoke evacuation tracheae of said combustion chamber and boiler respectively; The top of said combustion chamber is provided with blast pipe; Lower end, said combustion chamber is provided with fire grate, and this fire grate below is provided with grey storehouse, and the lower port in this grey storehouse is provided with the openable ash door of putting; On the chamber wall above the said fire grate, have dog-house, the air inlet of air-introduced machine and air outlet are communicated with the grey storehouse of said blast pipe and fire grate below respectively; Top in the fume removing and energy saving device enclosure interior is water tank, is provided with fire tube in the water tank, and the lower port of this fire tube is communicated with said combustion chamber, and the port of this fire tube is communicated with the flue gas case of said water tank top, and this flue gas case is provided with the fume pipe that is connected with blast pipe; The upper end of said water tank is provided with the hot-water outlet pipe who is communicated with boiler, and the lower end of said water tank is provided with water inlet pipe.The inlet of the said fume pipe that is connected with the boiler exhaust gas gas port and the inwall of combustion chamber are tangent.The utility model and prior art relatively have following 2 significant advantages:
1, unburned material can be complete through burn in the flue gas of boiler discharge, and the heat energy of the high-temperature flue gas that boiler is discharged obtains recycling;
2, the flue gas that produces of boiler separates dedusting and not to environmental emission or extremely slight fume emission is arranged in the device of the utility model, and is very friendly to environment.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Embodiment in conjunction with following describes in detail the utility model; Housing 1 bottom of the fume removing and energy saving device of the utility model is combustion chamber 3; The other end that advances fume pipe 2 that is connected with the boiler exhaust gas gas port is communicated with above-mentioned combustion chamber, is provided with blast pipe 9 on the top of this combustion chamber, is provided with fire grate 12 in this bottom, combustion chamber; On the burning chamber shell above this fire grate, have dog-house 11; Below the fire grate of above-mentioned combustion chamber, be provided with grey storehouse 13, the lower port in this grey storehouse is provided with the ash door 14 of putting to be opened/closed, and the air inlet of air-introduced machine 10 and air outlet are communicated with the fire grate of above-mentioned blast pipe and combustion chamber and the grey storehouse of putting between the ash door respectively.Above the port of above-mentioned combustion chamber, establish water tank 4, be evenly equipped with fire tube 6 in this water tank, the lower port of each fire tube is relative with above-mentioned combustion chamber, and the port of each fire tube is communicated with flue gas case 7, and the upper end cover of this water tank is provided with hot-water outlet pipe 8.
The operation principle of the utility model is; The smoke abatement and dust control energy saver of the utility model is the corollary equipment of boiler, is used for energy-conservation and smoke abatement and dust control, at first should in fume removing and energy saving device, knock down fuel through charging aperture; It is burnt in the combustion chamber; Start air-introduced machine simultaneously, the high-temperature flue gas that this moment, boiler produced is introduced in the combustion chamber, in the high-temperature flue gas by the most CO gas of burning and fine breeze carry out second-time burning laggard go in the water tank fire tube with water tank in water carry out heat exchange; The hot water that is produced is introduced into and produces steam or hot water in the boiler, and the flue gas rising gets into smoke box and is extracted into grey storehouse through fume pipe 5 by air-introduced machine.The high-temperature flue gas that is come out by the combustion chamber is in water tank after the heat exchange; Temperature descends and forms negative pressuren zone; The rotation in the annular chamber between device case and the combustion chamber shell of the particle of the after-flame in the flue gas separates and falls into grey storehouse, flue gas strile-back burn indoor, when piling up more for a long time; The discharge of ash door is put in unlatching, and the needed oxygen of combustion chambers burn is provided by air-introduced machine.Thereby the utility model improved the energy-saving effect of boiler, can practice thrift the cleaner of boiler simultaneously, and is more friendly to environment.
