Abstract

The utility model provides a tobacco curing hot-blast stove which comprises a stove body, hearths arranged in the stove body, flues communicated with the upper parts of the hearths, a grate, a feeding port and a tuyere arranged on the lower part of the hearth; the utility model is characterized in that at least two hearths arranged in the stove body through a separator part and the flues of the hearths are communicated with each other. According to the number of curing barns and the requirement of each curing barn, corresponding hearth capacity is selected so that the capacity of each hearth is utilized sufficiently to supply enough hot blast to each curing barn; the coal in hearths are in complete combustion state all the time; meanwhile, carbon particles, tar in fume and volatile matters are combusted again through the secondary air supply above the hearths; thereby, the combustion efficiency of fuel is greatly improved; the fuel consumption and the emission of smoke dust are reduced; the tobacco curing hot-blast stove can purify fume, protect environment and realize centralized curing and have no site occupation.

Description

Hot blast stove for flue-cured tobacco

Technical field

The utility model relates to a kind of hot-blast stove, and especially a kind of hot-blast stove that provides flue-cured tobacco to use hot blast to Tobacco leaf roasting room belongs to tobacco processing equipment design and manufacturing technology field.

Background technology

Traditional hot blast that hot blast stove for flue-cured tobacco produced only offers a corresponding bakery mostly and carries out tobacco flue-curing, the deficiency that this man-to-man heat-supplying mode brought is: one, cover tobacco flue-curing house because of the tobacco grower builds by every family basically, therefore take very rich and honour land resource; Two, single heat production, the mode of single heat supply will be wasted the limited energy such as fire coal or combustion gas; Three, by the tobacco workmanship requirement: in the flue-cured tobacco process, different baking stage requires to use the hot blast of different temperatures, and satisfying the tobacco workmanship requirement, and the fixedly burner hearth of single heat supply can't provide needed high temperature or low temperature hot blast in good time; Four, the regular meeting that is provided with of single burner hearth is incubated because of blowing out in the tobacco flue-curing process; perhaps kindling is heated; and cause coal-fired imperfect combustion; this imperfect combustion not only can cause coal-fired waste; the fine breeze and the powdered carbon of failing simultaneously to participate in burning can be drained with flue gas; both can in flue, form the dust stratification layer and reduced the heat exchange efficiency of radiator, again can be with the discharging of flue gas contaminated environment.Therefore, be necessary fully existing baking cigarette hot-blast stove is improved.

Summary of the invention

In order to solve the problems referred to above that existing hot-blast stove exists, the utility model provides a kind of energy-conservation, consumption reduction, thermal efficiency height, and can realize concentrating baking, the not hot blast stove for flue-cured tobacco of land occupation resource.

The utility model is finished by following technical proposal: a kind of hot blast stove for flue-cured tobacco, comprise body of heater, be located at the burner hearth in the body of heater, the flue that is communicated with upper furnace, be provided with fire grate, charge door and the blast orifice of lower furnace portion, it is characterized in that by separator two burner hearths being set at least in the body of heater, and the flue of each burner hearth is communicated with.So that light wherein one or more burner hearths as required, provide the hot blast of the required different temperatures of barn.

At least two burner hearths in the described body of heater are made as isometric burner hearth, perhaps are made as the burner hearth that large and small volume does not wait, so that select not isometric burner hearth ignition as required, so that the hot blast of the required different temperatures of barn to be provided.

Described each lower furnace portion is equipped with fire grate, be positioned at and be provided with corresponding coal filling hole and ash disposal mouth and blast orifice on the body of heater of fire grate upper and lower respectively, so that when selecting corresponding burner hearth work as required, coal, ash disposal and air blast easily, the normal combustion of assurance burner hearth.

Described each upper furnace is equipped with the secondary air mouth, and the secondary wind inleting tube that extends in burner hearth is housed on the air port, to provide combustion air to upper furnace, the particulate coal in the flue gas is fully burnt.

The utility model compared with prior art has following advantage and effect: adopt such scheme, adopt such scheme, an available hot blast stove for flue-cured tobacco provides required hot blast to many barns simultaneously, and according to barn quantity and each barn demand, select corresponding combustion space, the size that makes full use of combustion space provides sufficient hot blast to each barn, and make the fire coal in the burner hearth be in the completing combustion state all the time, improved fuel economy greatly, reduce fuel consumption, reduced the discharge capacity of flue dust; Secondary air by the burner hearth top burns carbon granules, the tar in the flue gas, fugitive constituent in the fire coal once more simultaneously; improved the fuel burn-off rate once more; further reduce the rafting amount of flue dust and imperfect combustion gas; purify flue gas; the protection environment is saved fire coal, has improved the thermal efficiency of hot-blast stove; realize concentrating baking, not land occupation.
