Abstract
The utility model discloses a vertical coal burning hot-blast stove, being composed of a hearth, five layers of sleeves, a hot-blast chamber and a long fume tube. The utility model is characterized in that four annular jackets are formed by the five layers of sleeves, and the high-temperature fume and air are separated and flow in the four jackets. The thermal efficiency can reach to 75 percent, the heating load is more than one million kilocalories per hour, and the total weight is 6.3 tons when the heating load is one million kilocalories per hour. The utility model has the advantages of adequate heat exchange, high thermal efficiency, considerable heating load, simple structure, small volume, light weight and easy manufacture.
Description
The utility model relates to a kind of heating and drying plant of hot-air central heating.It is a kind of vertical coal-fired hot-blast stove.
Existing vertical fire coal hot-blast stove heating load is all smaller, generally all 400,000 kilocalories/time below, otherwise volume is just very huge, gives and makes; Transportation, installation bring very big difficulty.
The purpose of this utility model provides that a kind of heating load is big, and simple in structure, volume is little, makes to be easy to the vertical fire coal hot-blast stove again.
For achieving the above object, this vertical fire coal hot-blast stove structurally is provided with five layers of sleeve, from outside to inside, be respectively ground floor sleeve, second layer sleeve, the 3rd layer of sleeve, the 4th layer of sleeve, layer 5 sleeve, the chuck of having formed four garden annulars by these five layers of sleeves, high-temperature flue gas and air flow respectively in these four chucks at interval, can make high-temperature flue gas and air carry out sufficient heat exchange.In the layer 5 sleeve, also be provided with the tubulation bundle, make high-temperature flue gas and air carry out a heat exchange again.Therefore the utility model heat transfer area is big, and heat exchange is abundant, and thermal efficiency height can reach 75%, and heating load is big, up to 1,000,000 kilocalories/time more than, and structure is simple, volume is little, and is in light weight, 1,000,000 kilocalories/time, gross weight has only 6.3 tons; It is easy again to make.
The utility model is taked following structure: as accompanying drawing 1, accompanying drawing 2, shown in the accompanying drawing 3, it comprises the burner hearth (1) that second layer sleeve (5) and burner hearth top cover (6) are formed, cold wind import (3), coal-feeding door (24), the ground floor air jacket (20) that ground floor sleeve (4) and second layer sleeve (5) are formed, the second layer air jacket (18) that the 3rd layer of sleeve (7) and the 4th layer of sleeve (8) are formed, air channel (21), hot blast chamber (16), hot-blast outlet (12), the ground floor high-temperature flue gas chuck (19) that second layer sleeve (5) and the 3rd layer of sleeve (7) are formed, the second layer high-temperature flue gas chuck (17) that the 4th layer of sleeve (8) and layer 5 sleeve (9) are formed, short smoke pipe (11), long smoke pipe (10), smoke-box (13), exhaust opening (14).Ground floor air jacket (20) and second layer air jacket (18) and hot blast chamber (16) are communicated with them by air channel (21).Ground floor high-temperature flue gas chuck (19) and second layer high-temperature flue gas chuck (17) are communicated with them by short smoke pipe (11).The later high-temperature flue gas of coal combustion in the burner hearth, enter in the ground floor high-temperature flue gas chuck (19) by several arcuate sockets (23) on the burner hearth top cover, with ground floor air jacket (20) in air and second layer air jacket (18) in air carry out heat exchange, enter in the second layer high-temperature flue gas chuck (17) by several short smoke pipes (11) again, with second layer air jacket (18) in air and hot blast chamber (16) in air carry out heat exchange, again carry out heat exchange with the outer air of pipe again in long smoke pipe (10), fume collecting chamber (13) is passed through in the back, exhaust opening (14), deduster, air-introduced machine and chimney enter atmosphere.Cold air by air blast is through air inlet (3), enter in the ground floor air jacket (20), absorb the heat that interior radiant heat of burner hearth and the interior flue gas of ground floor high-temperature flue gas chuck (19) are passed to, making it temperature raises, enter then in the second layer air jacket (18), absorb the heat that the interior flue gas of high-temperature flue gas chuck (19) and (17) is passed to, temperature further improves, carry out heat exchange by the interior flue gas of hot blast chamber (16) and tubulation (10) again, after reaching needed temperature, just discharge, be sent to the user by hot-blast outlet (12).
Embodiment of the present utility model is provided by accompanying drawing.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is the cutaway view of A-A among Fig. 1.
Fig. 3 is the schematic diagram of burner hearth top cover.
Wherein 1 is burner hearth, and 2 is fire clay, and 3 is the cold wind import, 4 is the ground floor sleeve, and 5 is second layer sleeve, and 6 is the burner hearth top cover, 7 is the 3rd layer of sleeve, and 8 is the 4th layer of sleeve, and 9 is the layer 5 sleeve, 10 are long smoke pipe, and 11 are short smoke pipe, and 12 is hot-blast outlet, 13 is fume collecting chamber, and 14 is exhaust opening, and 15 is tube sheet, 16 is the hot blast chamber, and 17 is second layer high-temperature flue gas chuck, and 18 is second layer air jacket, 19 is ground floor high-temperature flue gas chuck, 20 is the ground floor air jacket, and 21 is the air channel, and 22 is ash removing opening, 23 is the arcuate socket discharge flue, 24 is coal-feeding door, and 25 is boiler foundation, and 26 is fire grate.The operation principle of present embodiment and top narration are identical.
