Abstract
The utility model relates to a back-burning energy-saving atmospheric boiler, comprising a top water tank, an upper water tank, a middle water tank, a lower water tank, a water jacket of a boiler body, a boiler chamber, a secondary burning chamber, a triple burning chamber, a dust removing chamber, a hot water pipe and a flue, wherein, the top water tank, the upper water tank, the middle water tank, the lower water tank and the hot water pipe are communicated with the water jacket of the boiler body, and the boiler chamber, the secondary burning chamber, the triple burning chamber and the dust removing chamber are communicated with each other through the flue. The utility model has the advantages of good smoke eliminating and dust removing effect and high thermal efficiency, and the relevant indexes of fume discharge can reach the requirements of environmental protection.
Description
The utility model relates to a kind of normal-pressure boiler.
Present normal-pressure hot-water boiler generally is equipped with secondary combustion chamber, and flue gas is arranged to atmosphere from flue after second-time burning, but the relevant index of fume emission is difficult to reach environmental protection requirement, and the thermal efficiency of burning remains further to be improved.
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art part exactly, and the downward-burning type power-saving normal-pressure boiler that a kind of smoke medicining dust-removing effect is better, the thermal efficiency is higher is provided.
The utility model includes top water tank, upper water box, middle water tank, lower header, furnace water jacket, burner hearth, secondary combustion chamber, three combustion chambers, dirt pocket, hot-water line and flues.Lower header is between secondary combustion chamber and burner hearth, and middle water tank is between three combustion chambers and secondary combustion chamber, and upper water box is between dirt pocket and three combustion chambers, and the top water tank is positioned at the dirt pocket top.Be connected by furnace water jacket between top water tank, upper water box, middle water tank and the lower header, be connected by flue between dirt pocket, three combustion chambers, secondary combustion chamber, the burner hearth, be provided with hot-water line in the dirt pocket, hot-water line is connected with furnace water jacket, hot-water line is equidirectional to be arranged side by side, multi-layer intercrossed arrangement, flue gas when flowing through hot-water line, heat hot water pipe on the one hand, big soot particle in the flue gas falls and deposits through the obstruction of hot-water line on the other hand, thereby reaches the effect of dedusting.Flue includes inner chimney, side flue, central gas duct and other flue.Be provided with inner chimney in the water tank of top, dirt pocket is connected by the outer chimney of inner chimney and body of heater.Be provided with other flue between burner hearth and the secondary combustion chamber, other flue is located at around the burner hearth and the secondary combustion chamber periphery, arranges in the form of a ring.Be provided with central gas duct between three combustion chambers and the secondary combustion chamber, central gas duct is positioned at middle position.Be provided with the side flue between three combustion chambers and the dirt pocket, the side flue is positioned at a side of dirt pocket, and the inner chimney inlet is positioned at the dirt pocket opposite side relative with the side flue, the time of being detained in dirt pocket with the increase flue gas.
The utility model has been set up the combustion chamber three times, and flue gas returns burning utilization once more after flue arrives secondary combustion chamber and three combustion chambers, make burning more abundant, and flue gas is through the dedusting of dirt pocket hot-water line, and effect is better.
The utility model smoke medicining dust-removing effect is good, thermal efficiency height, and the relevant index of fume emission can reach environmental requirement, is applicable to each enterprises and institutions and the residential block of city, suburbs and tourist attractions.
Below in conjunction with description of drawings two embodiment of the present utility model.
Fig. 1 is the structural representation of the utility model list burner hearth type.
Fig. 2 is the structural representation of the utility model twin furnace type.
The boiler of water capacity below one ton generally can be considered miniature boiler, and its structure can adopt single burner hearth type structure shown in Figure 1.And bigger boiler or common boiler more than one ton can adopt twin furnace type structure shown in Figure 2.
Flue gas from burner hearth 13 through other flue 11 to secondary combustion chamber 10, again through 8 to three combustion chambers 7 of central gas duct, be provided with cleaning door in dirt pocket 3 bottoms, on secondary combustion chamber 10 and three combustion chambers 7, be equipped with adjustable secondary air register, to regulate the combustion position of flue gas.Top water tank 2, upper water box 6, middle water tank 9, lower header 12 and hot-water line 4 all are communicated with furnace water jacket 15.Fire grate 14 is positioned at bottom of furnace body.
To single burner hearth type structure, the body of heater shape is with circular or square for well.To twin furnace type structure, the body of heater shape is with ellipse or rectangle the best.
