Abstract

The utility model discloses a multi-flue boiler with ash removing ring. a smoke box water jacket 7 is disposed on one side of a boiler body water jacket; a smoke returning channel 10 is in communication with a hearth; a smoke evacuation chamber 11 is disposed under the bottom board of the smoke box water jacket 7; a chimney 12 is disposed on the top wall of the side of the smoke evacuation chamber11; a plurality of flue pipes 13 are disposed in the smoke box water jacket 7; an ash removing ring 14 is disposed in each flue pipe 13; the top end of the pull bar 15 of the ash removing ring 14 isdisposed on the frame 16 on the end face water jacket 9; a support bar 17 is disposed under the frame 16 with two ends connected with tooth gage 18; the tooth gage 18 is inserted into the gage slot 19, while is engaged with a gear 20 on the upper end; and a rocking handle 21 is disposed on the gear 20. The water in the smoke box water jacket absorbs the waste heat of the smoke in the flue pipe, and energy is saved. The ash removing ring disposed in the flue pipe can be utilized to scrape dust, not only is beneficial to smoke evacuation, but also prevents the dust from separating heat. A long flue is composed by the smoke returning channel, the flue pipe, the smoke evacuation chamber and the chimney; the dust in smoke drops in the flue, thereby the flue dust emission is very little, and theair pollution is reduced.

Description

The thickness road boiler of band deashing ring

Technical field

The utility model relates to a kind of boiler.

Background technology

Mostly the cigarette of existing boiler is directly to discharge body of heater by chimney, and the waste heat of not only failing to make full use of in the cigarette improves the thermal efficiency, causes the waste of the energy, and contains a large amount of coal dusts in the cigarette that is directly emitted, cause air pollution.The boiler design that has also attempts to improve boiler by the way that prolongs flue, but because it has considered prolongation flue this point, and has ignored the dedusting of flue deashing, and the result makes the dust that deposits in the flue have a strong impact on the raising of the thermal efficiency.

Summary of the invention

The purpose of this utility model is to provide a kind of thickness road boiler of band deashing ring of energy-conserving and environment-protective.

Technical solution adopted in the utility model is, the thickness road boiler of this band deashing ring, comprise water inlet pipe, outlet pipe, fire door, the ashes door, stove rod plate, one side of furnace water jacket is established a smoke box water jacket, it joins with furnace water jacket and communicates, constitute smoke returning flue between its top board and the end face water jacket, smoke returning flue communicates with burner hearth, connect in the floor below of smoke box water jacket and to establish the smoke evacuation chamber, establish chimney on the side roof of smoke evacuation chamber, a plurality of flue tubes are set in the smoke box water jacket, establish the deashing ring in it, the top of the pull bar of deashing ring is connected with on the framework on the end face water jacket, framework is divided into support bar, and the support bar two ends connect tooth gauge, and tooth gauge inserts in the rule groove, at upper end and gear mesh, establish rocking handle on the gear.

Owing to taked technique scheme, so being water in the smoke box water jacket, the utility model one can fully absorb by the waste heat of cigarette in a plurality of flue tubes of its encirclement, reduce the temperature of cigarette, the raising thermal efficiency reaches energy-conservation purpose.The 2nd, all be provided with the deashing ring in each flue tube, utilize this device, all can strike off the dust that sinks on the flue tube inwall easily at any time, both be beneficial to smoke evacuation, prevented the dust thermal resistance again, influenced flue tube waste heat in the cigarette is conducted to water on every side, provide further guarantee for improving the thermal efficiency.The 3rd, smoke returning flue, flue tube, smoke evacuation chamber, chimney have constituted a long flue, cigarette discharge process will be wherein dust sink in above-mentioned flue, it is few to be disposed to airborne fume amount, has reduced air pollution.
