Abstract
A heating hot-blast stove is used for heating places of homes, small breeding spaces, temporary small plants and the like, and overcomes the shortcomings of low air temperature and slow indoor temperature rising of an existing hot-blast stove with the functions. The heating hot-blast stove comprises a vertical stove casing, a fire grate, an ash chamber, a combustion chamber smoke exhaust port, a radiating body and a circulation air channel, wherein the radiating body and the circulation air channel are arranged in the stove casing. The heating hot-blast stove is characterized in that the radiating body comprises a combustion chamber provided with a lateral wall and an upper bottom and arranged in the stove casing, a plurality of vertical heat exchange smoke pipes communicated with the combustion chamber and smoke buffer tanks arranged at the upper ends of the heat exchange smoke pipes. The heating hot-blast stove has the advantages that the heat exchange area of smoke and circulation air is large, heat exchange is full, hot blast flow is large, the temperature is high, the temperature in the heating space rises quickly, the heat space is enlarged, and heat value utilization rate of fuel is improved.
Description
Technical field
The invention belongs to the heating field, be specifically related to family or the small-scale production field is used for heating.
Background technology
Shanty town in the rural area that does not have public heating equipment, small town and city is all adopted or be aided with the combustion furnace heating of making fuel with coal stove or faggot cold season.Traditional approach with the combustion furnace heating is only to utilize body of heater and the long heat that is arranged in indoor flue (being commonly called as the stove tube) radiation, and efficiency of utilization is low, and the heating space is heated up slow.Along with development of technology and people live, the lifting of production demand level.Most other or small-scale animal and plant that use the combustion furnaces heating are cultured water or the air that factory building that greenhouse and short-term use progressively used process and combustion furnace to carry out heat exchange and are come the temperature-rising heating space.The air with circulation heating space wherein is simple in structure because of it, few with material with the heating hot-air stove that combustion furnace carries out heat exchange, cost is low, the space quick heating of warming oneself, and advantage, the large percentage that is used such as can arbitrarily be moved in the body of heater position.Mostly the structure of existing heating hot-air stove is to add furnace body, in body of heater flame above upper and lower dislocation be oppositely arranged the flat cylindricality circulating air Heat Room that the horizontal cross-section is semicircle or large semicircle.The stove outer air blasts from the cool air intlet of low level air Heat Room, gets into high-order air Heat Room the communicating pipe between the upper and lower Heat Room, and the hot air outlet from high-order Heat Room flows out again.Heat exchange area is little in the stove of this kind heating hot-air stove, and heat exchanger time is short, has more heat to be taken out of outside the stove by flue gas, and the wind-warm syndrome of the hot blast of discharge is low, and indoor intensification is slow.
Summary of the invention
The purpose of this invention is to provide a kind of heating hot-air stove, be used for the temperature-rising heating in places such as family, small-sized breed space, interim little factory building, it is low to overcome the wind-warm syndrome that the hot-blast stove of existing this type of purposes exists, the deficiency that indoor intensification is slow.
Hot-blast stove of the present invention comprises the fire grate that install the bottom in vertical furnace shell, the furnace shell, the grey chamber of fire grate below and the fuel combustion chamber of fire grate top, radiator in the body of heater exhaust opening of furnace upper end, furnace shell and the circular air channel between radiator and the furnace shell; The improvement of being done is: the radiator in the furnace shell has combustion chamber that is surrounded by sidewall and upper base and the several setting heat exchange smoke pipes that are communicated with combustion chamber and exhaust opening, and sidewall of combustion chamber and furnace shell leave and establish annular wind isolation board between spacing, side wall lower ends and the furnace shell.
Be the speed of dashing on the reduction flue gas is in the heat exchange smoke pipe; Lengthening flue gas holdup time in body of heater; Increase the surface area of radiator, the flue gas baffle-box that the upper end of heat exchange smoke pipe is established by sidewall, upper base, gone to the bottom and surround in furnace shell, flue gas baffle-box sidewall and furnace shell leave spacing; Going to the bottom is communicated with the heat exchange smoke pipe, and upper base is established the smoke exhaust pipe that stretches out furnace shell.
For make the wind that blasts from furnace shell one side in the furnace shell lower end can be all and be distributed in around combustion chamber and the heat exchange smoke pipe; Annular homogenating plate is arranged between sidewall of combustion chamber above the air inlet and furnace shell; Be distributed with air-permeating hole on the homogenating plate, the air-permeating hole away from air inlet strengthens successively gradually.
Air heat process of the present invention is: the flame in the combustion chamber burns the sidewall of combustion chamber and the end; Hot cigarette is time heating tube wall through the heat exchange smoke pipe; Cool air from the import of furnace shell bottom get into furnace shell, space between the space between combustion chamber and furnace shell, heat exchange smoke pipe and furnace shell and mutual space, flue gas baffle-box and furnace shell is mobile; Draw the heat of radiator in flowing, the exit on furnace shell becomes hot blast, sprays into space to be heated.The flue gas of discharging from heat exchange smoke pipe upper end, through the baffle-box buffering, the exhaust opening on baffle-box enters the pipeline that is connected with chimney.
Good effect of the present invention is: flue gas and the circulating air heat exchange area is big, heat exchange is abundant, and hot air flow is big, temperature is high, and heating quick heating heat supply space, space increases, and has improved the utilization rate of heat value of fuel.
Description of drawings
Fig. 1 looks cutaway view for master of the present invention.
Fig. 2 is a vertical view cutaway drawing of the present invention.
The specific embodiment
Consult Fig. 1, Fig. 2, the fire grate 2 that install the bottom in comprising vertical furnace shell 1, furnace shell, the grey chamber 3 below the fire grate, the hot-blast stove of the exhaust opening 4 of furnace upper end.In furnace shell, establish with furnace shell and leave spacing, have the steel plate structure combustion chamber 5 of sidewall and upper base, the annular wind isolation board 6 of welding between the lower end of combustion chamber 5 sidewalls and the furnace shell, heat exchange smoke pipe 7 is erect in three of combustion chamber upper base welding; The flue gas baffle-box 8 that the upper end of heat exchange smoke pipe 7 is established by sidewall, gone to the bottom in furnace shell 1, upper base surrounds leaves spacing between the sidewall of flue gas baffle-box 8 and the furnace shell 1, and flue gas baffle-box 8 is gone to the bottom and is connected with heat exchange smoke pipe 7, and upper base connects exhaust opening 4.On furnace shell, establish air inlet 9 near the lower end, combustion chamber, annular homogenating plate 10 is arranged between sidewall of combustion chamber above the air inlet 9 and furnace shell, be distributed with air-permeating hole 11 on the homogenating plate, air-permeating hole begins to become gradually big from air inlet.The furnace shell top sets out air port 12, form by 9 mouthfuls of air inlets through the combustion chamber 5 with 1 space of furnace shell 1, smoke exhaust pipe 7 and furnace shell 1, flue gas baffle-box 8 and furnace shell at last to the circulating air of air outlet 12 heat recipient passage that circulates.
