Abstract

Disclosed is a horizontal air warming furnace utilizing wastes as fuel. A hearth (1) is arranged in a hermetical air warming chamber (2), an air outlet (5) is arranged on an upper portion of the air warming chamber (2), an air inlet (8) is arranged on a lower portion of the air warming chamber (2), an air blower (9) is arranged on the air inlet (8), a fire bar (7) is arranged on a lower portion of the hearth (1), and a chimney (10) is arranged on an upper portion of the hearth (1). The horizontal air warming furnace utilizing the wastes as the fuel is characterized in that the air warming furnace is arranged horizontally, which means the vertical height of the hearth (1) is smaller than the forth-back width of the same, shapes of front views of the hearth (1) and the air warming chamber (2) are circular or rectangular, and a surface shape of the hearth (1) is a continuous 'S' or an arc. When the surface of the hearth (1) is in the shape of the arc, a plurality of heating fins (11) are arranged on the outer surface of the hearth (1), and an insulating layer (3) or the insulating layer (3) and a light reflection film (4) are arranged outside the air warming chamber (2).

Description

Utilize the horizontal hot-blast stove of discarded object for fuel

Affiliated technical field

The utility model relates to a kind of heating equipment, particularly a kind of horizontal hot-blast stove that utilizes discarded object for fuel.

Background technology

In the vast rural area of China, a large amount of agricultural crop straws, waste mulching film and leaf are taken as waste incineration or landfill, cause great environmental pollution and energy waste at present; And the heliogreenhouse of northern China generally has only the insulation measure in the winter time because the coal fuel cost is very high, does not heat measure; Vegetables in day-light greenhouse output is had a strong impact on; Make the dish valency higher, drive price rise simultaneously, farmers' income reduces.So, heat the bottleneck problem that becomes restriction heliogreenhouse economic benefit the winter of heliogreenhouse, if can utilize the rural area widely discarded object heat to heliogreenhouse for fuel, can reduce environmental pollution on the one hand; Can make full use of inexhaustible regenerative resource on the other hand, still, traditional hot-blast stove generally is to be main with high burning-point fuel such as coals; Because the gas permeability of coal is better, burning-point is higher, so; The grate area of this hot-blast stove is generally less, and burner hearth is darker, so; This hot-blast stove is generally vertical setting, that is: the vertical height of burner hearth is greater than its front and back width, still; This hot-blast stove can not be fuel with the discarded object of gas permeability extreme difference, and for this reason, the utility model provides a kind of horizontal hot-blast stove that utilizes discarded object for fuel; It can make full use of agricultural crop straw, waste mulching film and leaf etc. is fuel, has both reduced the pollution of environment, has sufficiently and reasonably utilized the energy again.

Summary of the invention

In order to achieve the above object, the utility model provides a kind of horizontal hot-blast stove that utilizes discarded object for fuel.

The technical scheme that the utility model solves its technical problem is:

A kind of horizontal hot-blast stove that utilizes discarded object for fuel at the indoor burner hearth that is provided with of airtight warm braw, sets out the air port on top, warm braw chamber; The bottom is provided with air inlet; Air blast is set on the air inlet, in lower furnace portion fire bars is set, top is provided with chimney, it is characterized in that: the burner hearth of hot-blast stove and warm braw chamber are the cylindrical or rectangle of lateral recumbent posture; Fire door vertically is provided with, that is: the burner hearth vertical height is less than width before and after the burner hearth; The surface configuration of burner hearth is continuous serpentine or arc, during for arc, at the burner hearth outer surface heat exchange fin is set; At the outdoor heat-insulation layer that is provided with of warm braw, perhaps at outdoor heat-insulation layer and the reflective membrane of being provided with of warm braw.

When hot-blast stove was lighted, the warm braw chamber was heated, and air blast is blown into cold air from air inlet, and after air was heated, hot-air circulated under the effect of deflector and blows out from air outlet, sent into the heliogreenhouse that needs heating.The horizontal setting of hot-blast stove is for the grate area maximization, increases oxygen-supplying amount; Promote burning, the surface configuration of burner hearth is arranged to continuous serpentine or arc, during for arc; Establishing the hot fin of some displacements at the burner hearth outer surface, is in order to increase the surface area of heat exchange, to increase the heat exchange effect; At the outdoor heat-insulation layer that is provided with of warm braw, be in order to reduce the heat radiation of warm braw chamber, to reduce thermal losses perhaps at outdoor heat-insulation layer and the reflective membrane of being provided with of warm braw.
