Abstract
The utility model discloses an environment protection energy-saving coal combusting hot-air stove which comprises an air blower, a lower stove body, a main heat exchanger, a subsidiary heat exchanger and a chimney, wherein a ring-shaped air chamber is arranged at the circumference of a combustion chamber above a stove grate of the lower stove body; the ring-shaped air chamber is communicated with the air blower; a secondary air inlet ring is arranged between the combustion chamber and the ring-shaped air chamber; a plurality of air inlet small holes are arranged on the secondary ring; the rest of the ring-shaped air chamber is sealed. The utility model has the characteristics of low smoke discharging concentration, sufficient fuel combustion, good surplus heat utilization, etc., and is a novel environment protection energy-saving coal combusting hot-air stove.
Description
The utility model relates to a kind of coal-fired hot-blast stove, and is especially relevant with the environmental protection and energy saving coal-fired hot-blast stove.
Coal-fired hot-blast stove is the heat that utilizes coal combustion to produce, add hot-air by heat exchanger, thereby for drying equipment provides a kind of equipment of hot blast, a large amount of at present coal-fired hot-blast stoves that use generally adopt the primary combustion technology, and smoke density is higher, cause environmental pollution, the thermal efficiency is also relatively low, the anti-burning technology of the employing that also has, but because complex structure, cost is higher, is difficult to promote in popular drying equipment.
The purpose of this utility model is to provide a kind of smoke density lower, compliance with environmental protection requirements, the environmental protection and energy saving coal-fired hot-blast stove that the thermal efficiency is higher relatively.
For achieving the above object, technical solution of the present utility model is: the environmental protection and energy saving coal-fired hot-blast stove, comprise hair-dryer, lower furnace body, main heat exchanger, auxiliary heat exchanger and chimney, be provided with annular wind chamber around the combustion chamber above the grate of lower furnace body, annular wind chamber is communicated with hair-dryer, is provided with the secondary air ring between combustion chamber and the annular wind chamber, be provided with some air intake apertures on the secondary air ring, all the other all seal annular wind chamber.
Described environmental protection and energy saving coal-fired hot-blast stove is provided with the cold wind thermal insulation layer at the outer wall of main heat exchanger, is provided with the lower end air admission hole in cold wind thermal insulation layer bottom, and the auxiliary heat exchanger position is provided with spiral flow deflector on chimney.
Described environmental protection and energy saving coal-fired hot-blast stove, the air intake aperture on the secondary air ring is evenly distributed, and the air intake aperture becomes same acute angle setting with the secondary air plane of a loop.
The utility model has been owing to adopted technique scheme, thereby has following beneficial effect: (one) is that smoke density obviously reduces, and environment protecting is obvious; (2) be that fuel combustion is comparatively abundant, waste heat is fully used, and energy-saving effect is obvious.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the overall structure schematic diagram of the utility model environmental protection and energy saving coal-fired hot-blast stove.
Fig. 2 is the structural representation and the partial enlarged drawing of the utility model environmental protection and energy saving coal-fired hot-blast stove lower furnace body.
As shown in Figure 1, the utility model environmental protection and energy saving coal-fired hot-blast stove comprises hair-dryer 1, lower furnace body 2, main heat exchanger 3, auxiliary heat exchanger 4 and chimney 5, be provided with annular wind chamber 6 around the combustion chamber 15 above the grate of lower furnace body, annular wind chamber 6 is communicated with hair-dryer 1, be provided with secondary air ring 7 between combustion chamber 15 and the annular wind chamber 6, as shown in Figure 2, on secondary air ring 7, be provided with some air intake apertures 8 that are evenly distributed, and air intake aperture 8 becomes same acute angle setting with the secondary air plane of a loop, and all the other all seal annular wind chamber 6, is provided with cold wind dottle pin layer 9 at the outer wall of main heat exchanger 3, be provided with lower end air admission hole 14 in cold wind thermal insulation layer 9 bottoms, auxiliary heat exchanger 4 positions are provided with spiral flow deflector 10 on chimney 5.Its course of work is: combustion chamber 15 internal combustion of the coal seam after on fire above lower furnace body 2 grates 11, and to 2 minutes two tunnel forced air supplies of lower furnace body, the one tunnel passes grate 11 and coal seam through grey storehouse 12, to satisfy the required air capacity of coal combustion by hair-dryer 1; Another road enters annular wind chamber 6 back air intake apertures 8 from wind top of chamber inboard and upwards sprays to the burner hearth center, under the condition of burner hearth high temperature, imperfect combustion gas produces second-time burning after obtaining oxygen replenishment, form a conical fire curtain, fire box temperature is further improved, the burning of fuel is more abundant, thereby reaches the purpose that reduces smoke density.High-temp waste gas after the burning drains into outside the stove through main heat exchanger 3 and chimney 5.Cold air then from the top of the auxiliary heat exchanger 4 that is located at chimney 5 outer walls in the shape of a spiral shape import, behind the waste heat that absorbs chimney 5, enter main parallel operation 3 again, the temperature of air is further improved, and the air-introduced machine 16 of the equipment that is dried then is negative pressure from the air outlet of main heat exchanger 3 and draws.Be located at the cold wind thermal insulation layer 9 of main heat exchanger 3 outer walls, because the bottom of thermal insulation layer outer wall has several lower end air admission holes 14, the top of thermal insulation layer links to each other with the inner chamber of main heat exchanger 3, thereby under the effect of main heat exchanger inner chamber negative pressure, cold air enters main heat exchanger 3 again after lower end, the bottom air admission hole 14 of thermal insulation layer 9 outer walls enters into top, thereby makes the temperature of cold wind thermal insulation layer 9 outer walls remain on suitable scope.
