Abstract
The utility model relates to a screw type warm wind furnace, which comprises a furnace seat and a furnace body which is arranged on the furnace seat and is composed of thermal insulation cotton, an outer chamber and an inner chamber. A wind inlet, an exhaust duct and a discharge flue are arranged on the furnace body. The technical characteristic of the utility model is that a spiral fire channel and a spiral wind channel are arranged between the outer chamber and the inner chamber; each layer of the spiral fire channel is arranged below each layer of the spiral wind channel, the upper end and the lower end of the spiral fire channel are respectively communicated with the discharge flue and a furnace cavity, and the upper end and the lower end of the spiral wind channel are respectively communicated with the exhaust duct and the wind inlet; a fire-separating baffle, the bottom opening of which is large, and the upper opening of which is small is arranged on the lower part in the furnace cavity. The smoke fire which is produced when fuel is burned enters the furnace cavity through the bottom of the fire-separating baffle to pass through the spiral fire channel after the smoke fire returns to the lower part to be discharged from the discharge flue; in the process, the cold wind which is transported from the wind inlet and flows through the spiral wind channel is heated to form the warm wind to be transported outside from the exhaust duct. The utility model has the characteristic that the fuel can be fully burned to cause heat efficiency to be improved to cause energy to be saved, and the utility model is favorable for environmental protection.
Description
Technical field:
The utility model relates to a kind of boiler, a kind of specifically spiral hot-blast stove.
Background technology:
At present, generally the boiler of Shi Yonging mostly adopts inner hanging chamber, fiery crack pipe etc., the heat that coal combustion produces all in burner hearth, edge part conducts heat, and makes the heat major part be discharged into atmosphere with flue dust from smoke exhaust pipe, not only waste energy, nor be beneficial to environmental protection.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind ofly can reach smoke abatement and dust control, help the higher spiral hot-blast stove of the energy savings and the thermal efficiency again.
The purpose of this utility model is to realize like this, it comprises the stove seat and places the body of heater that is made of heat-preservation cotton, outer courage, inner bag on the stove seat, this body of heater is provided with air inlet, exhausting duct and smokejack, it is characterized in that: be provided with spirality quirk and spirality air channel outside between courage and the inner bag, each layer of spirality quirk is all below each layer of spirality air channel, the spirality quirk is connected with smokejack and burner hearth respectively at two ends up and down, and the spirality air channel is connected with exhausting duct and air inlet respectively at two ends up and down; In burner hearth the bottom be provided with end mouth big, on the young fiery baffle plate of branch.The pyrotechnics that fuel produces when burning enters burner hearth by the bottom of minute fiery baffle plate, returns down the back by the spirality quirk, is discharged by smokejack; Cold wind (or cold water) heating that to be sent into and be flowed through the spirality air channel by air inlet in this process, the warm braw after the heating is transferred out by exhausting duct.
The utility model has the advantages that fuel combustion time lengthening, furnace heating surface is long-pending to be strengthened, and can make full combustion of fuel, improve the thermal efficiency greatly, makes it energy savings, helps environmental protection.
Below in conjunction with accompanying drawing the utility model is explained.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment:
By accompanying drawing as can be known, the utility model mainly comprise stove seat 11, air inlet 10, divide fiery baffle plate 6, smokejack 1, exhausting duct 2 and the body of heater that constitutes by heat-preservation cotton 3, outer courage 13, inner bag 12, spirality quirk 4, spirality air channel 14 and coal feeding hole 9, fire bars 8, ash hole 7.The body of heater that is made of heat-preservation cotton 3, outer courage 13, inner bag 12, spirality quirk 4, spirality air channel 14 places on the stove seat 11.Air inlet 10, exhausting duct 2 and smokejack 1 are located on the body of heater.Spirality quirk 4 and spirality air channel 14 are located between outer courage 13 and the inner bag 12, each layer of spirality quirk 4 is all below 14 each layer of spirality air channel, the spirality quirk is connected with smokejack 1 and burner hearth 5 respectively at two ends about in the of 4, and the spirality air channel is connected with exhausting duct 2 and air inlet 10 respectively at two ends about in the of 14; End mouth is big, upward the young fiery baffle plate 6 of branch is located at bottoms in the burner hearth 5.
