Description
Technical field
The utility model belongs to greenhouse, cattle breeding field to be provided air heating or provides the low profile thermal wind furnace of heated-air drying agricultural product, particularly small-sized induced air type indirect hot-blast stove.
Background technology
At present, the small-sized indirect hot-blast stove that heliogreenhouse is used to heat mostly is welded with the thick steel plate in the 2mm left and right sides.This hot-blast stove is through the steel plate heat-transfer surface and heat exchange with high-temperature flue gas and air.Heat-transfer surface (steel plate) side is the high-temperature flue gas that smells up to more than 1,000 degree, and opposite side is heated air.The flow velocity of air side, flow direction affects the temperature of heat-transfer surface, the small-sized indirect thermal wind furnace made from the sheet metal welding in China, the heat exchange of strengthening air side all is to blow mode, this mode can cause the local cooling of heat-transfer surface bad, area of dissipation is little, fast-selling boss is low, part still temperature is very high, under high temperature corrosion and high-temperature oxidation environment, the high temperature heat-transfer surface can peel off from level to level, and local temperature is still very high, until burning, make the small-sized indirect hot-blast stove shortening in service life of sheet metal weldering, this is to weld small-sized indirect hot blast stove design with the thick sheet metal of 1.5～3mm at present, difficult problem during production.
The utility model content
The purpose of this utility model is to provide a kind of small-sized induced air type indirect hot-blast stove, and it is rational in infrastructure, and heat exchange area is big, thermal efficiency height, fuel savings, and long service life.
The purpose of this utility model is achieved in that a kind of small-sized induced air type indirect hot-blast stove, comprise the combustion chamber that has fire grate, the hot-blast stove housing that is provided with on the top of combustion chamber body of heater, on the hot-blast outlet pipe that its top is provided with air-introduced machine is installed, in the hot-blast stove housing, setting gradually heating clamber from inside to outside, hot blast chamber and flue box, the top seal of heating clamber wherein, its underpart and combustion chamber are connected as a single entity, the top of flue box and bottom lock, the flue of uniform setting is communicated with flue box on the sidewall on heating clamber top, be communicated with chimney on the hot-blast stove housing at the smokejack that is provided with on the sidewall of flue box bottom, air inlet in the uniform setting of hot-blast stove lower housing portion is communicated with the bottom of hot blast chamber, and the top of hot blast chamber is communicated with the hot-blast outlet pipe of hot-blast stove case top.
During the utility model work, coal is in the combustion chamber internal combustion, the high-temperature flue gas that produces enters from the bottom of heating clamber, rises to heating clamber top flue of uniform setting from its sidewall and turns back and enter flue box downwards, and the smokejack that is provided with from the flue box lower sides enters chimney and discharges; Air enters the bottom of hot blast chamber from air inlet, rise along the hot blast locular wall, because the inwall of hot blast chamber is heated the high-temperature flue gas heating of chamber, the fume afterheat heating that the hot blast chamber outer wall is turned back and moved downwards by flue box, the outer wall and the flue box inwall that enter indoor air of hot blast and heated heating clamber carry out heat exchange fully, heat exchange area is big, thermal efficiency height.Heated air is sucked by air-introduced machine and is transported to the work-yard by hot air duct.Since cold air from the bottom enter, fully carry out heat exchange when upwards moving, make cold air heat absorption take away the heat of heating clamber outer wall and flue box inwall, the temperature of high temperature heat-transfer surface is reduced.Through actual measurement, when the air outlet hot blast temperature reached 70 ℃ of design loads, the temperature of heating clamber outer wall had prevented to constitute the steel plate of locular wall by high temperature corrosion about 200 ℃ effectively.The utility model is rational in infrastructure, and heat exchange area is big, thermal efficiency height, fuel savings, and long service life.
