Detailed description of the invention
With reference to the accompanying drawings the specific embodiment of the present invention is described.
Embodiment one
With reference to Fig. 1, Fig. 2, for the low-noise energy-saving combustion chamber of compression combustion furnace, comprise combustion chamber main body 1, the hollow region of combustion chamber main body 1 is combustion zone 10; Combustion zone 10 is made up of the combustion cell 11 of arranging successively from bottom to top, ring-shaped depression 12 and reducing district 13; Ring-shaped depression 12 is arranged around combustion chamber main body 1 madial wall.Fuel burns in combustion cell 11 and produces flame, and flame is sprayed by the fire end that goes out at the top of combustion chamber main body 1 successively by combustion cell 11 behind ring-shaped depression 12, reducing district 13.The concave surface of ring-shaped depression 12 is a cambered surface, and the top of ring-shaped depression 12 was connected along 131 cambered surface transition along 121 with the end in above-mentioned reducing district 13, and the end of ring-shaped depression 12 is connected along 111 cambered surface transition along 122 with the top of above-mentioned combustion cell 11.The vibrational power flow of ring-shaped depression 12 of the present invention can play good rectified action to flame flow, and then effectively reduces the noise of combustion furnace running, flame flow can either be concentrated and go out, and noise is again to control, and remains on about 50 decibels; In addition, the setting of this ring-shaped depression 12, increase the stroke that fuel is upwards climbed to along combustion chamber main body 1 inwall, and the expansion of ring-shaped depression 12 the latter half can reduce current rate, reduce the thrust of fuel oil, and then part fuel oil is strapped in this ring-shaped depression 12, thus effectively reduce the number of dropouts of fuel oil with air-flow, improve the utilization rate of fuel oil, reduce the use cost of combustion furnace.
Continue with reference to Fig. 1, Fig. 2, above-mentioned reducing district 13 is for upper and lower end is large and structure that middle part is little, reducing district 13 sidewall is provided with a line second air admission hole 132, this row is made up of the second air admission hole 132 that 12 are evenly arranged, and this second air admission holes 132 all are from bottom to top and tilt to extend to the right and arrange.And above-mentioned combustion cell 11 is up-narrow and down-wide structure, be provided with the installing hole 110 for fitting into oil nozzle bottom combustion cell 11, combustion cell 11 sidewall is circumferentially provided with the first air admission hole 112 of evenly arrangement.Above-mentioned combustion cell 11 is provided with two row first air admission holes 112, and this first air admission holes 112 all are from bottom to top and tilt to extend to the left and arrange, the number of lastrow first air admission hole 112 is 12, and the number of next line first air admission hole 112 is 24.By the first air admission hole 112 and the second air admission hole 132 opposition towards setting, the air entered by the second air admission hole 132 is made to produce a corrective action to the flame flow rotated, the flame flow in combustion zone 10 is made not rotate motion, This reduces both noise, also the track area that flame contacts with sidewall of combustion chamber is effectively reduced, reduce the waste of flame heat energy, ensure the flame temperature going out combustion chamber, improve the utilization rate of the energy.In addition, combustion cell 11 inwall is provided with the annular oil partition tank 113 of circumference distribution, this annular oil partition tank 113 bottom land is located in the inner of this first air admission hole 112 of lastrow, the setting of this annular oil partition tank 113 can stop fuel oil upwards to be creeped further, and the fuel oil blowout flowing to annular oil partition tank 113 can be burnt by the first air admission hole 112 of annular oil partition tank 113 bottom land to combustion cell 11, thus improve the utilization rate of fuel oil further.
Continuing with reference to Fig. 2, is the structure of downward-sloping extension to pool wall direction by middle part at the bottom of above-mentioned combustion cell 11 pond.Such vibrational power flow, when combustion furnace is stopped using, the surplus oil put aside in combustion cell 11 can rest on base angle, pond and fall, and this can reduce the volatilization face area of surplus oil, and the air-flow of flowing also not easily falls through base angle, pond, thus makes surplus oil not volatile.
Embodiment two
Present embodiment and embodiment one difference are the frame mode of ring-shaped depression 12.With reference to Fig. 3, the ring-shaped depression 12 of present embodiment is made up of upper loop concave 123 and lower loop concave 124, and upper loop concave 123 and lower loop concave 124 are cambered surface structure, and the diameter of upper loop concave 123 is greater than the diameter of lower loop concave 124; The top of upper loop concave 123 was connected along 131 cambered surface transition along 121 with the end in above-mentioned reducing district 13, and the end of lower loop concave 124 is connected along 111 cambered surface transition along 122 with the top of above-mentioned combustion cell 11.
Above are only the specific embodiment of the present invention, but design concept of the present invention is not limited thereto, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should belong to the behavior of invading scope.
